    To investigate the career plans of prospective dental students and how they foresee their work life balance. Applicants to Dundee and Manchester dental schools completed anonymous questionnaires when they attended for interview. The useable response rate was 94% (n=436). The majority of the respondents (91.3%) intended working full time when they enter the workforce, with no significant variation detected between males and females. The cohort anticipated their mean salary to be just over 28,000 UK pounds, five years into their career, although the males felt they would be earning 5,000 UK pounds more than the females. Individuals of Pakistani and Indian origin thought they would earn most, and Asians least. Sixty-five per cent would enter general dental practice and, of these, only 2.8% expected to work exclusively within the NHS. Fifteen per cent intended to go into the hospital dental service, with orthodontics the most popular choice of subspecialty (43.7%), followed by oral surgery (31.1%). Significant variation was seen between ethnic groups, with the hospital and community dental services being more popular with those who identified themselves as of non-white ethnic origin, although the majority would still plan on entering general dental practice. Almost half (44.5%) would take time out of their career to concentrate on childcare when children were of pre-school age, with a further 11% taking longer. Ninety per cent of females and 70% of males anticipated taking time out, of a varying duration. Half of the respondents indicated that they felt a child would affect their career to a moderate extent. The dental profession will be severely affected if both males and females take time out of their careers in the future. As well as a work force shortage, the problems of accessibility to NHS dental services will be exacerbated if fewer dentists choose to provide NHS care.

  2. Dental school finances: current status.

    Total expenditures and revenues of 58 US dental school were derived from reports of the ADA Division of Educational Measurements. These financial data were studied by type of dental school (public, state-related private, and private) and by expenditure/revenue categories. Dental schools showed little diversity in expenditures: most were directed toward instruction; few were directed toward research or continuing education. Several distinctive patterns among the three types of dental schools in revenues were observed. Two configurations emerged: public and state-related private dental schools receive more than 75% of their revenues from government and tuition, and private dental schools, more than 50%.

    2005-01-01

    The definition of continuing dental education is presented, along with its benefits to the profession. The preeminence of dental schools in providing lifelong learning opportunities and freedom from commercial involvement that existed even twenty years ago has changed. Less than a quarter of CE takes place in school, and the focus there is increasingly on material with deep scientific background and hands-on learning. The newest innovations and those with the greatest commercial potential are taught elsewhere. Proposed changes in the ADA CERP standards would take on a "purist" approach that could place dental schools at a severe disadvantage while allowing "for profit" institutes to flourish and thus further undermine the role dental schools can play in providing quality professional development experiences.

    Masella, Richard S

    2005-04-01

    A career in dental academics offers ample rewards and challenges. To promote successful careers in dental education, prospective and new dental faculty should possess a realistic view of the dental school work environment, akin to the informed consent so valuable to patients and doctors. Self-assessment of personal strengths and weaknesses provides helpful information in matching faculty applicants with appropriate dental schools. Essential prehiring information also includes a written job description detailing duties and responsibilities, professional development opportunities, and job performance evaluation protocol. Prehiring awareness of what constitutes excellence in job performance will aid new faculty in allotting time to productive venues. New faculty should not rely solely on professional expertise to advance careers. Research and regular peer-reviewed publications are necessary elements in academic career success, along with the ability to secure governmental, private foundation, and corporate grant support. Tactful self-promotion and self-definition to the dental school community are faculty responsibilities, along with substantial peer collaboration. The recruitment period is a singular opportunity to secure job benefits and privileges. It is also the time to gain knowledge of institutional culture and assess administrative and faculty willingness to collaborate on teaching, research, professional development, and attainment of change. Powerful people within dental schools and parent institutions may influence faculty careers and should be identified and carefully treated. The time may come to leave one's position for employment at a different dental school or to step down from full-time academics. Nonetheless, the world of dental and health professional education in 2005 is rapidly expanding and offers unlimited opportunities to dedicated, talented, and informed educators.

    The curriculum for graduating dental and dental hygiene students must prepare them to contribute to the improvement or maintenance of health for individual patient's and the public's health. The objective is to describe the background for and the process used to develop a core Dental Public Health Curriculum for such students. The process used was to solicit and review existing dental public health curriculum in dental and dental hygiene schools; review curriculum for other health professionals; identify the themes needed to frame the curriculum; select usable materials and identify gaps in existing curricular materials; and develop appropriate curriculum materials that would embody the competencies developed for undergraduate dental and dental hygiene education. Twenty-three topics were identified as embodying the eight competencies. Based on these topics, six courses, Principles of Dental Public Health, Evidence-Based Dentistry, Ethics and Dental Public Health, Dental Public Health Policy and Advocacy, Oral Health Promotion and Disease Prevention, and Oral Health Literacy and Dental Public Health, were prepared. Each course includes syllabus, PowerPoint presentations, student assignments and activities, instructor guide, and classroom discussion points. Depending on the hours available in the existing curriculum at the dental or hygiene school, lecture presentations and take home assignments/discussions may be used independently or in combination with presentations from other courses. In addition, individual discussions and activities may be used to integrate dental public health materials into other courses. A flexible curriculum is available at the AAPHD website to enable the incorporation of DPH topics into the curriculum. © 2015 American Association of Public Health Dentistry.

    Library and academic websites are among the most reliable Internet resources available today. Schools of all types use the Internet as a means of sharing information; and libraries provide broader access to their collections via the Web. For researchers seeking specific, authoritative resources on dental history, library and dental school websites are most helpful in identifying print and online resources, in describing manuscript collections, and in presenting a history of the host institution. A library site often can provide sufficient information online to eliminate the need for an in-person visit to the library. On the other hand, a library site may tantalize the historian with enough information on unique collections that a trip can be justified.

    2015-06-01

    The application of surface topography measurement and characterization within dental materials science is highly active and rapidly developing, in line with many modern industries. Surface measurement and structuring is used extensively within oral and dental science to optimize the optical, tribological and biological performance of natural and biomimetic dental materials. Although there has historically been little standardization in the use and reporting of surface metrology instrumentation and software, the dental industry is beginning to adopt modern areal measurement and characterization techniques, especially as the dental industry is increasingly adopting digital impressioning techniques in order to leverage CAD/CAM technologies for the design and construction of dental restorations. As dental treatment becomes increasingly digitized and reliant on advanced technologies such as dental implants, wider adoption of standardized surface topography and characterization techniques will become evermore essential. The dental research community welcomes the advances that are being made in surface topography measurement science towards realizing this ultimate goal.

    2018-03-01

    The aim of this study was to evaluate the use of the dental school admissions interview score as a noncognitive indicator of performance in predoctoral dental education, with specific attention to whether a correlation existed between the admissions interview scores and performance on the objective structured clinical examination (OSCE). The study population consisted of all 175 students in the Harvard School of Dental Medicine (HSDM) DMD Classes of 2012 through 2016. Data on students' gender and age on entering dental school were self-reported using their applications for admission to the HSDM DMD program. Data on students' OSCE scores for three examination sessions were collected from the Office of Dental Education. The results showed that the students' interview scores did not significantly correlate with OSCE performance on any of the three exams. Performance on the first and second OSCEs did, however, correlate with performance on the third OSCE (pinterview score. These results suggest that although the admissions interview scores can serve as an important resource in student selection, with the lack of association between interview and OSCE scores, it is possible that the communication skills required for the interview do not directly overlap with those required for OSCE success.

    2018-05-01

    Practice management has become an increasingly important aspect of dental education over the years in order to better prepare students for the reality of practice. The aim of this study was to quantify and describe practice management courses taught at the ten Canadian dental schools in order to identify common approaches, compare hours, determine types of instructors, and assess the relationship between courses' learning objectives and the Association of Canadian Faculties of Dentistry (ACFD) competencies and Bloom's cognitive levels. The academic deans at these ten schools were surveyed in 2016; all ten schools responded for a 100% response rate. The authors also gathered syllabi and descriptions of the courses and analyzed them for themes. The results showed a total of 22 practice management courses in the ten Canadian dental schools. The courses provided 27 to 109 hours of teaching and were mostly taught in the third and fourth years and by dentists on three main topics: ethics, human resource management, and running a private practice. The courses were correlated to the ACFD competencies related to ethics, professionalism, application of basic principles of business practices, and effective interpersonal communication. Most of the courses' learning objectives addressed comprehension and knowledge in Bloom's cognitive levels of learning. These results can help to guide discussions on how practice management courses can be developed, improved, and refined to meet the challenges of preparing students for dental practice.

    2018-03-01

    An Integrated National Board Dental Examination (INBDE) combining basic, behavioral, and clinical sciences will be implemented in 2020 to replace the current two-part National Board Dental Examination required for all candidates who seek to practice dentistry in the U.S. The aims of this study were to determine how U.S. dental schools are preparing for implementation of the INBDE and to assess their top administrators' attitudes about the new exam. A total of 150 deans, academic deans, and other administrators at all 64 U.S. dental schools with graduating classes in 2016 were emailed a 19-question electronic survey. The survey questions addressed the respondents' level of support, perceived benefits and challenges, and planned preparation strategies for the INBDE. The individual response rate was 59%, representing 57 of the 64 schools. Approximately 60% of the respondents either agreed or strongly agreed that they support the integrated exam, while roughly 25% either somewhat or strongly disagreed. While most respondents (72%) reported that their institutions would be prepared for the INBDE, 74% reported that the merged exam created additional strain for their institutions. Respondents reported viewing content integration and clinical applicability as benefits of the INBDE, while required curriculum changes and student preparedness and stress were seen as challenges. Most of the respondents reported their schools were currently employing strategies to prepare for the INBDE including meetings with faculty and students and changes to curricula and course content. The beginning of the fourth year and the end of the third year were the most frequently reported times when schools planned to require students to take the INBDE, although almost half of the respondents did not yet know what it would be required at their school. Several schools were reconsidering using the boards as a passing requirement. This study found that support for the INBDE was not universal, but

    This article summarizes the current status of the operation and management of dental school clinics as schools strive to provide excellent patient-centered care in an environment that is educationally sound, efficient, and financially strong. Clinical education is a large component of dental education and an area in which many dental schools have an opportunity to enhance revenue. Clinical efficiencies and alternative models of clinical education are evolving in U.S. dental schools, and this article describes some of those evolutionary changes. This article was written as part of the project "Advancing Dental Education in the 21 st Century."

    As the number of dental hygiene programs across the country continues to increase, educational opportunities for prospective students have flourished, resulting in increased competition among dental hygiene programs for qualified applicants. The purpose of this study was to provide a current description of dental hygiene students and applicants, assess the reasons for choosing the career, and evaluate the perceptions of both applicants and enrolled students with regard to specific aspects of the profession. A questionnaire was mailed to 142 prospective dental hygiene students who met the minimal requirements for admission to either of the two dental hygiene programs in Arkansas. The prospective students had been invited for an admissions interview. The questionnaire also was administered during class to 80 students currently enrolled in one of the two programs. An overall response rate of 71% (n = 157) was achieved. The average respondent was 22 years old, female, and Caucasian with a grade point average of 3.5 and a composite ACT score of 23. Dental hygiene was also the first career choice and most respondents had prior dental assisting experience. Dental hygienists and dentists were reported as providing the most career guidance, while high school and college guidance counselors were least influential. Respondents chose the profession in order to work with and help people, have flexible work schedules, and receive good salaries. Respondents typically viewed dental hygiene as offering a bright future in terms of job security, good salaries, flexible work schedules, diverse career opportunities, and personal responsibility. No significant difference in overall perceptions of the profession was found between applicants and those enrolled in dental hygiene programs, although the strength of individual perceptions of the profession differed between applicant and first-year students compared to second-year students. Dental hygiene programs can use the findings of this

    2010-08-14

    Advances of composite systems and their application have revolutionised the management of posterior teeth affected by caries, facilitating a minimally invasive approach. Previous surveys have indicated that the teaching of posterior composites within dental schools was developing, albeit not keeping pace with clinical evidence and the development of increasingly predictable techniques and materials. Concurrently, surveys of dental practice indicate that dental amalgam still predominates as the \\'material of choice\\' for the restoration of posterior teeth within UK general dental practice. In light of such considerations, the aim of this study was to investigate current teaching of posterior composites in Irish and UK dental schools.

    2006-09-01

    During the last decade, cultural competency has received a great deal of attention in health care and the literature of many fields, including education, social services, law, and health care. The dental education literature provides little information regarding status, strategies, or guiding principles of cultural competency education in U.S. dental schools. This study was an attempt to describe the status of cultural competency education in U.S. dental schools. A web-based thirty-question survey regarding cultural competency education coursework, teaching, course materials, and content was sent in 2005 to the assistant/associate deans for academic affairs at fifty-six U.S. dental schools, followed up by subsequent email messages. Thirty-four (61 percent) dental school officials responded to the survey. The majority of respondents (twenty-eight; 82 percent) did not have a specific stand-alone cultural competency course, but indicated it was integrated into the curriculum. Recognition of local and national community diversity needs prompted course creation in most schools. Respondents at almost two-thirds of schools indicated that their impression of students' acceptance was positive. Teachers of cultural competency were primarily white female dentists. Few schools required faculty to have similar cultural competency or diversity training. Thirty-three of the thirty-four U.S. dental schools responding to this survey offer some form of coursework in cultural competency with little standardization and a variety of methods and strategies to teach dental students.

    Full Text Available The term "work-related musculoskeletal disorders (WMSDs," refers to musculoskeletal disorders to which the work environment contributes significantly, or to musculoskeletal disorders that are made worse or longer lasting by work conditions or workplace risk factors. In recent years, there has been an increase in reporting WMSDs for dental persons. Risk factors of WMSDs with specific reference to dentistry include - stress, poor flexibility, improper positioning, infrequent breaks, repetitive movements, weak postural muscles, prolonged awkward postures and improper adjustment of equipment. Ergonomics is the science of designing jobs, equipment and workplaces to fit workers. Proper ergonomic design is necessary to prevent repetitive strain injuries, which can develop over time and can lead to long-term disability. In this article, 20 strategies to prevent WMSDs in the dental operatory are discussed.

    2015-06-01

    This report presents findings from a survey of U.S. dental school deans designed to capture their perceptions regarding the rising cost of dental education and its impact on borrowing by dental students to finance their education. The survey included questions about factors influencing the cost of dental education, concerns about dental student borrowing, and financial awareness resources for students. The survey was distributed to the deans of all 63 U.S. dental schools in January 2013; 42 deans responded, for a 67% response rate. The results indicate that, according to the responding deans, new clinical technologies, technology costs, and central university taxes are the main factors that contribute to the increasing cost of dental education. Coupled with reduced state appropriations at public dental schools and declines in private giving at all dental schools, dental school deans face a perplexing set of financial management challenges. Tuition and fees are a primary source of revenue for all dental schools; however, many deans do not have total control over the cost of attending their schools since tuition and fees are often tied to mandates and policies from the parent university and the state legislature. The findings of this study indicate that U.S. dental school deans are aware of and concerned about the impact of increases in tuition and fees on dental student debt and that they are using a variety of strategies to address the growth in dental student borrowing.

    2017-05-01

    This report examines the results of the American Dental Education Association (ADEA) Survey of Dental School Seniors graduating in 2016. Data were collected from 4,558 respondents at all 59 U.S. dental schools with graduating classes that year. This annual survey asks graduating students about a variety of topics in order to understand their motivation for attending dental school, educational experiences while in school, debt incurred, and plans following graduation. Motivations for choosing to attend dental school typically involved family or friends who were dentists or students' personal experiences. The timing of the decision to enter dentistry has been getting earlier over time. Similar to previous years, the average graduating student had above $200,000 in student debt. However, for the first time in two decades, inflation-adjusted debt decreased slightly. The reduction in debt was due to students from private schools reducing their average debt by $23,401. Immediately after graduation, most seniors planned to enter private practice (50.5%) or advanced dental education (33.8%). Approximately half of the respondents planned to work in underserved areas at some point in their careers. These findings underscore the continued value of the senior survey to offer a unique view of the diverse characteristics and career paths of the future dental workforce.

    Wanchek, Tanya N; Rephann, Terance J

    2013-01-01

    Southwest Virginia is a rural, low-income region with a relatively small dentist workforce and poor oral health outcomes. The opening of a dental school in the region has been proposed by policy-makers as one approach to improving the size of the dentist workforce and oral health outcomes. A policy simulation was conducted to assess how a hypothetical dental school in rural Southwest Virginia would affect the availability of dentists and utilization levels of dental services. The simulation focuses on two channels through which the dental school would most likely affect the region. First, the number of graduates who are expected to remain in the region was varied, based on the extensiveness of the education pipeline used to attract local students. Second, the number of patients treated in the dental school clinic under different dental school clinical models, including the traditional model, a patient-centered clinic model and a community-based clinic model, was varied in the simulation to obtain a range of additional dentists and utilization rates under differing dental school models. Under a set of plausible assumptions, the low yield scenario (ie private school with a traditional clinic) would result in three additional dentists residing in the region and a total of 8090 additional underserved patients receiving care. Under the high yield scenario (ie dental pipeline program with community based clinics) nine new dentists would reside in the region and as many as 18 054 underserved patients would receive care. Even with the high yield scenario and the strong assumption that these patients would not otherwise access care, the utilization rate increases to 68.9% from its current 60.1%. While the new dental school in Southwest Virginia would increase the dentist workforce and utilization rates, the high cost combined with the continued low rate of dental utilization suggests that there may be more effective alternatives to improving oral health in rural areas

    2015-03-01

    This study examined water fluoride levels at schools across Western Australia. The aim was to identify schools where levels of water fluoride appeared to be below dental health thresholds (0.5-1.0 mg/L) as recommended by the National Health and Medical Research Council (NHMRC). The objective is to provide health organizations with the knowledge for a more targeted approach to schools with greater risk of decay. Population data, school location, enrolment data and water quality data were integrated into geographic databases for analysis using Quantum GIS, Lisboa 1.8. The results indicated that 46% of school attendees in the northern half of Western Australia were at schools where there was the potential that the water was not dentally optimally fluoridated while in the southern half of Western Australia this was about 10%. Of these attendees (north and south), 45% were at primary school. Similarly, there was an association between socio-economic decile and proportion of school attendees in non-dentally optimally fluoridated schools. Lower deciles (i.e. poorer attendees) had a greater risk of being in schools outside dentally optimally fluoridated areas. This study clearly highlights areas where more prevention (and probably) treatment needs are present and provides a framework for targeted service planning. © 2015 Australian Dental Association.

  12. Gender differences in first-year dental students' motivation to attend dental school.

    2002-08-01

    Women's role in the field of dentistry has historically been limited to the dental auxiliary fields, rather than that of D.D.S. or D.M.D. Today, women are nearly 38 percent of U.S. dental school students and 14 percent of active practitioners. The slow(er) influx of women into dentistry has been little studied by dental educators. During the 2000-01 academic year, we conducted a survey of first-year dental students at a sample of publicly funded U.S. dental schools. The purpose of the survey was to assess gender differences in motives for pursuing a dental career. The data show that male dental students rate self-employment and business-related motives as more important, while female dental students rate people-oriented motives more highly. Factor analysis revealed four distinct clusters of motives for pursuing a dental career: a financial motive, a business-oriented motive, a people-oriented or caring motive, and a flexibility motive. Women scored significantly higher than men on the caring factor, whereas the reverse was true on the business factor. Male and female students rated financial and flexibility motives equally. The implications of the results for attracting students to the profession of dentistry are discussed.

    Full Text Available Choosing dental color for missing teeth or tooth reconstruction is an important step and it usually raises difficulties for dentists due to a significant amount of subjective factors that can influence the color selection. Dental reconstruction presumes the combination between dentistry and chromatics, thus implying important challenges. Purpose: The aim of this study was to develop and implement a software application for detecting dental color to come to the aid of dentists and largely to remove the inherent subjectiveness of the human vision. Basic Methods: The implemented application was named Color Detection and the application’s source code is written using the C++ language. During application development, for creating the GUI (graphical user interface the wxWidgets 2.8 library it was used. Results: The application displays the average color of the selected area of interest, the reference color from the key collection existent in the program and also the degree of similarity between the original (the selected area of interest and the nearest reference key. This degree of similarity is expressed as a percentage. Conclusions: The Color Detection Program, by eliminating the subjectivity inherent to human sight, can help the dentist to select an appropriate dental color with precision.

    It is well known that there is a large disparity between the proportions of African Americans, Hispanics, and American Indians in the general U.S. population and in the nation's dental profession. While these underrepresented minorities (URMs) together make up almost 30 percent of the population, they comprise only about 6 percent of U.S. dentists. For years, the American Dental Education Association has been diligently working with U.S. dental schools to reduce this disparity by increasing the diversity of their student bodies. However, with approximately 13 percent of first-year dental students coming from URM groups, the proportion of URM students entering dental school continues to remain significantly below that of the general population. Diversifying the dental profession is important for improving access to care for underrepresented groups, and student diversity provides better educational experiences for all students. Texas A&M Health Science Center Baylor College of Dentistry's strategy for increasing the number of URM dentists was to create a series of initiatives that together form a successful comprehensive program addressing students' awareness of and attraction to a dental career, academic enrichment, admissions, and graduation. The cumulative impact of this program is that the college enrolled greater numbers and proportions of URM students than any other non-minority U.S. dental school from 2006 to 2009. This article describes the program that led to these successes.

    Electronic health records (EHRs) are a major development in the practice of dentistry, and dental schools and dental curricula have benefitted from this technology. Patient data entry, storage, retrieval, transmission, and archiving have been streamlined, and the potential for teledentistry and improvement in epidemiological research is beginning to be realized. However, maintaining patient health information in an electronic form has also changed the environment in dental education, setting up potential ethical dilemmas for students and faculty members. The purpose of this article is to explore some of the ethical issues related to EHRs, the advantages and concerns related to the use of computers in the dental operatory, the impact of the EHR on the doctor-patient relationship, the introduction of web-based EHRs, the link between technology and ethics, and potential solutions for the management of ethical concerns related to EHRs in dental schools.

    Recently, there has been increased attention to including cultural diversity in the education of health professionals, including concern for lesbian, gay, bisexual, and transgender (LGBT) inclusion and visibility. Studies regarding cultural exposure and acceptance of LGBT populations have been concentrated in medicine, with findings showing that medical providers often graduate having missed the preparation required to care for LGBT persons. A visible, comprehensive, culturally competent environment in dental schools would help ensure that all oral health professionals and students are aware of services available to address the particular needs of LGBT students. The aims of this survey-based study conducted in 2015-16 were to determine dental students' perceptions regarding LGBT students' needs and to assess dental students' knowledge of resources for LGBT persons at three U.S. dental schools, one each in the Midwest, West, and South. Of the 849 students invited to participate, 364 completed the survey (338 dental, 26 dental hygiene), for an overall response rate of 43%. The response rate at individual schools ranged from 30% to 55%. The results showed perceptions of insufficient LGBT information, resources, and support at these institutions, especially at the Western school. There were significant differences among the three schools, with students at the Western school more than the other two schools perceiving that their institution was less aware of whether it met the academic, social support, and spiritual needs of LGBT students. There were no significant differences between LGBT and non-LGBT students' perceptions. The authors urge dental school administrators to explore the degree to which their programs teach respectful and caring behavior towards LGBT students and, by extension, LGBT patient populations.

    The study aimed to assess the awareness of the Consumer Protection Act among dental health professionals in dental schools of Ghaziabad, India. A cross-sectional questionnaire survey was carried out on dental health professionals in dental schools of Ghaziabad, India. A total of 348 dental health professionals (170 males and 178 females) were surveyed, out of which 116 were MDS faculty, 45 were BDS faculty and 187 were pursuing post graduation. The questionnaire comprised of 24 questions about the awareness of consumer protection act. Statistical analysis was done using Chi-square test, student's t test and ANOVA. A total of 84.8% (n=295) reported to be aware of consumer protection act. Amongst them, MDS faculty showed more awareness as compared to BDS faculty and those pursuing post-graduation. Considering the present scenario, MDS faculty dental professionals have more awareness of consumer protection act compared to other dental professionals. So, we must upgrade our knowledge on consumer protection act at all levels of our profession and change our attitude by inculcating a practice to spread the message of consumer protection act for delivering quality dental care.

    Background Much concern appears to exist as to the scope and content of contemporary dental school programmes, with the oft-cited criticism being made that dental graduates are 'no longer as good as they used to be'.Aim The aim of this project was to survey the views of dentists - both new graduates and more established practitioners - on aspects of their own dental school training they felt had been deficient as well as commenting on what aspects of dental school education they would like to see improved/enhanced in current times.Methods An invitation to complete an Internet-based questionnaire was emailed to the Fellows and Members of the Faculty of General Dental Practice (UK). Topics in the questionnaire included the respondent's own dental education history, how well they felt their dental school training had covered certain clinical and non-clinical topics; and their opinions on areas they felt should be included in contemporary dental school programmes.Results Six hundred and forty-nine responses were received from 3,348 emailed invitations (response rate = 19.4%). Sixty-one percent (395) of respondents were qualified for 10 years or more. Among clinical skills and techniques, a majority of respondents reported they felt they had not had sufficient teaching/training in dental school in surgical endodontics (76%), conscious sedation (72%), root surface debridement (71%), fixed orthodontic appliances (68%), porcelain veneers (63%), implants (56%) and posterior composites (53%). If designing a new dental school programme, the most common topics respondents would seek to include/increase were business and practice management (21%), communication skills (including patient management and leadership skills) (10%), and increased clinical time and experience (8%).Conclusions The findings of this project are of interest and relevance to those working with student dentists and young dental practitioners. A greater emphasis is needed on the teaching of certain non

    The University of Washington School of Dentistry may be the first dental school in the nation to apply lean process management principles as a primary tool to re-engineer its operations and curriculum to produce the dentist of the future. The efficiencies realized through re-engineering will better enable the school to remain competitive and viable as a national leader of dental education. Several task forces conducted rigorous value stream analyses in a highly collaborative environment led by the dean of the school. The four areas undergoing evaluation and re-engineering were organizational infrastructure, organizational processes, curriculum, and clinic operations. The new educational model was derived by thoroughly analyzing the current state of dental education in order to design and achieve the closest possible ideal state. As well, the school's goal was to create a lean, sustainable operational model. This model aims to ensure continued excellence in restorative dental instruction and to serve as a blueprint for other public dental schools seeking financial stability in this era of shrinking state support and rising costs.

    To determine the degree of psychological distress, the experience of emotional exhaustion, and the extent of stress associated with course work in dental students and to compare these measurements among seven European dental schools. Multi-centred survey. Dental Schools at Amsterdam, Belfast, Cork, Greifswald, Helsinki, Liverpool and Manchester. 333 undergraduate first-year dental students. General Health Questionnaire (GHQ12), Maslach Burnout Inventory (MBI), Dental Environment Stress Questionnaire (DES), demographic variables. Questionnaire administered to all students attending first year course. Completed questionnaires sent to central office for processing. Seventy-nine percent of the sampled students responded. Over a third of the students (36%) reported significant psychological distress (morbidity) at the recommended cut-off point (>3 on GHQ). These scores were similar to those reported for medical undergraduates. Twenty-two percent recorded comparatively high scores on emotional exhaustion. A wide variation in these 2 measurements was found across schools (p'sStress levels indicated by the DES were less variable (p>0.5). Some evidence showed that contact with patients and the level of support afforded by living at home may be protective. Higher than expected levels of emotional exhaustion were found in a large sample of first-year undergraduate dental students in Europe.

    The objectives of the study reported in this article were to assess dental student leaders' perceptions of educational efforts concerning lesbian, gay, bisexual, and transgender (LGBT) topics and the cultural climate concerning LGBT issues in dental schools in the United States and Canada. In addition, the perceptions of student leaders who self-identified as belonging to the LGBT community and of students with a heterosexual orientation were compared. Data were collected from 113 dental student leaders from twenty-seven dental schools in the United States and three in Canada. Fifty student leaders were females, and sixty-two were males. Only 13.3 percent of the respondents agreed that their dental education prepared them well to treat patients from LGBT backgrounds. The more the student leaders believed that their university has an honest interest in diversity, the better they felt prepared by their dental school program to treat patients from LGBT backgrounds (r=.327; pschools' administrations create a positive environment for students with LGBT orientations, the more they agreed that persons can feel comfortable regardless of their sexual orientation (r=.585; pschool administrators play an important role in ensuring that future care providers are well prepared to treat patients from LGBT backgrounds and that staff, faculty, students, and patients from these backgrounds are not discriminated against.

    Marked social inequalities in oral health are observed right from early childhood. A mandatory complete health check-up, including dental screening, is organized at school for 6-year-old children. School healthcare professionals are not well trained in dental health. The aim of this study was to assess the relevance of an illustrated guide as a simple and rapid dental screening training tool in order to ensure effective, standardized and reproducible screening. A cross-sectional study was conducted in the context of the dental examination performed as part of the health check-up. Two examiners (Doctor E1 and Nurse E2) were trained in dental screening by means of the illustrated guide. This reference guide, comprising pictures and legends, presents the main oral pathology observed in children. 109 consent forms for oral screening were delivered, and 102 children agreed to participate (93.57%). The sensitivity of detection of tooth decay by examiners E1 and E2 was 81.48% with a specificity of 96%. No correlation was observed between the child's age (+/- 6 years) and correct detection rates. The illustrated guide is an appropriate and rapid tool for dental screening that can improve the quality of dental check-up and increase the number of children detected.

    A Commission on Dental Accreditation (CODA) standard now requires that dental schools commit to establishing a "humanistic culture and learning environment" for all members of the academic environment. The aim of this study was to identify students' perceptions of factors that affect the dental school environment and to test differences in their experiences in terms of gender and year. This picture of the existing environment was meant to serve as a first step toward creating and supporting a more humanistic academic environment. A mixed-methods approach was used for data collection during the 2009-10 and 2010-11 academic years at one U.S. dental school. Four focus groups were first conducted to explore challenges and conflicts faced by students during their dental education. A written survey informed by the focus group results was then used to obtain quantitative data. The survey response rate was 47 percent (N=188). Faculty inconsistency, cheating, and belittlement/disrespect were experienced by many of the responding dental students during their education, similar to what has been documented in medicine. These students also reported experiencing both constructive communication (90 percent) and destructive communication (up to 32 percent). The female students reported more gender discrimination and sexual harassment than their male peers, and the clinical students reported more experience with belittlement and destructive communication than the preclinical students. The results suggest that greater effort should be directed toward creating a more humanistic environment in dental schools. Based on the issues identified, steps academic institutions can take to improve these environments and student skills are outlined.

    The aim of this study was to re-examine the teaching of geriatric dentistry in the USA dental schools, to identify curriculum content and compare the findings to previous reports. All dental schools in the United States were contacted via email with a questionnaire to assess the teaching of geriatric dentistry. Non-responding schools were sent a minimum of three reminder emails to complete the survey. A statistical analysis was performed. Descriptive statistics were conducted to profile the variables of interest. Bivariate analysis was performed to explore if any of the variables were related using Fisher's exact test, non-parametric Wilcoxon rank-sum test and the Kruskal-Wallis test. Fifty-six of the 67 dental schools completed the questionnaire. Geriatric dentistry was taught in all dental schools; for 92.8%, the course was compulsory. We found that 62.5% were teaching it as an independent course, 25% as an organised series of lectures and 8.9% as occasional lectures in parts of other courses. Clinically, 84.2% have some form of compulsory education in geriatric dentistry. Public schools were marginally associated with an increased interest in expanding the geriatric dentistry curriculum (P = .078). No differences were found between these variables and school location. Geriatric dentistry is now required in 92.8% of dental schools. The teaching of traditional topics has not changed much; however, the number of gerontological topics has increased. Clinical teaching needs to be expanded, as in only 57.1% of schools was it a requirement. The ageing imperative will require research to determine the impact of teaching on services to the geriatric community. © 2017 John Wiley & Sons A/S and The Gerodontology Association.

    Full Text Available BACKGROUND Dental caries is a universal health problem with involving the people globally of all regions and society. The agonising fact is that despite several efforts towards total eradication, dental caries is still prevalent. As the prevalence of dental caries is very high among school children and there is a paucity of such data in Coimbatore and the literature review does not reveal many such studies from this area, the study was conducted in the school going children in Sulur. MATERIALS AND METHODS All the students were screened visually using torch with the help of mouth mirror and probe and the observation recorded. A health screening camp was conducted for the students in private school, Sulur, February 20-25, 2017, by a team of doctors from PSG UHTC. A total of 1945 students were screened. The students health details have been entered in their health card and those requiring further evaluation have been counseled and the nursing staff at school has been requested to facilitate and guide for followup. All the students were screened visually using torch with the help of mouth mirror and probe and the observation recorded. All the students who were present in school during 20th to 25th were screened and considered as the inclusion criteria. The exclusion criteria were the absentees during this period. The students were made to sit in an ordinary chair in broad daylight facing away from the sunlight and examined in their school. Data were compiled in an excel worksheet and the percentage calculated. RESULTS A total of 1945 students were screened, of which, 541 students were found to have dental problems that is about 28% of the total screening done. The percentage of dental caries were found to be higher compared to other dental diseases like deep caries, malalignment, malocclusion and calculus. The percentage of dental caries was found to be higher in the females about 78% than the male for whom it was about 72%. The percentage of deep

Bivariate statistical analyses were performed. RESULTS: Fifteen percent of the students reported being sexually harassed by a patient, by a relative of a patient or by a professor. Male students had 3 times higher probability of being sexually harassed than female student [OR=2.910 (1.113-7.611]. Additionally, 25.4% of the students reported witnessing sexual harassment at the school environment. The majority of students did not feel professionally prepared to respond to unwanted sexual behaviors. CONCLUSION: These findings demonstrate that sexual harassment can occur in a dental school setting. There is a need for ongoing sexual harassment education programs for students and university staff. Increased knowledge of sexual harassment during graduation can better prepare dental professionals to respond to sexual harassment during their practice.

    In recent decades many guidelines has been conducted by radiation protection organizations about radiation protection in dentistry. This study aimed to evaluate the observance of these guidelines in educational clinics of all dental schools in Iran. Material and Methods: In this cross-sectional study a self-administered questionnaire, based on National Radiation Protection Board and European Commission guidelines, was conducted. The radiology departments of all dental school (18 schools) were surveyed in this study. The questionnaire was consisted of 3 sections including intraoral radiography, extra oral radiography and implementation of quality control programs. Results: In the case of the existence of radiation protection facilities (such as lead apron, thyroid shield and lead impacted walls) the use of high speed films and existence of automatic processor in dental schools, there was a proper condition. The main problem was related to lack of regular quality control and quality assurance programs. Digital radiography systems were employed in none of the schools and it was occasionally used for research purposes at some of them. Conclusions: This study has emphasized on the need for further consideration of radiation protection principles in dental schools, especially on the field of quality control and quality assurance programs.

  13. Porous Titanium for Dental Implant Applications

    2015-10-01

    Full Text Available Recently, an increasing amount of research has focused on the biological and mechanical behavior of highly porous structures of metallic biomaterials, as implant materials for dental implants. Particularly, pure titanium and its alloys are typically used due to their outstanding mechanical and biological properties. However, these materials have high stiffness (Young’s modulus in comparison to that of the host bone, which necessitates careful implant design to ensure appropriate distribution of stresses to the adjoining bone, to avoid stress-shielding or overloading, both of which lead to bone resorption. Additionally, many coating and roughening techniques are used to improve cell and bone-bonding to the implant surface. To date, several studies have revealed that porous geometry may be a promising alternative to bulk structures for dental implant applications. This review aims to summarize the evidence in the literature for the importance of porosity in the integration of dental implants with bone tissue and the different fabrication methods currently being investigated. In particular, additive manufacturing shows promise as a technique to control pore size and shape for optimum biological properties.

    An increasing number of graduates of foreign dental schools who enroll in advanced standing programs to qualify for licensure calls for dental schools to be prepared to handle not only the curricular demands but also the growing cultural diversity among its student population. The "reeducation" of this student group not only meets the need of foreign dentists for an American degree but may also provide health professionals to service various ethnic populations whose language and culture they are able to understand and identify with. A survey of students and graduates of a two-year Program for Advanced Standing Students (PASS) for graduates of foreign dental schools representing 34 countries aimed to arrive at an understanding of this student group through characterization of the foreign dentists and identification of their attitudes and feelings toward various aspects of the program, the school and faculty and their experience of stress. This report includes description of the distinctive features of the program which cater to specific needs and concerns of this non-traditional group of dental students. PASS students are accepted on the basis of their grades in dental school in home country, scores in the National Dental Board Examination Part I, Test of English as Foreign Language (TOEFL), and ratings in personal interviews. They complete an intensive summer program consisting of didactic and laboratory courses which prepares them for integration with four-year students for the last two years of didactic and clinical curriculum. Cultural diversity seminars, a special English class, PASS class meetings and seminars are unique additions to their program and aim to assist them adjust to the educational, social and cultural systems in an American school.

    Education for oral-dental health in children is that component of general health education aimed at creating cultural health models, cultivating in the young generation a healthy hygienic behaviour and outlying the opinions about the ways dental disorders can be prevented and treated. The most important goal of health education is to contribute to the preservation/improvement of children's oral health status. This study has two main goals: to assess the exact health education knowledge of the questioned parents and to evaluate their involvement in the oral health education and promotion. This study included 95 parents, aged between 25 and 49 years, with children in primary schools. For data collection a questionnaire was used. The questions were grouped on common features: food habits and healthy diet, causes of oral disease, prevention of oral disease, dental visit habits, oral hygiene habits. The study revealed that parents have a moderate knowledge about dental health education and dental caries prevention, no significant sex differences being found, and poor knowledge about periodontal diseases prevention. As to food hygiene, parents proved a sound knowledge about healthy and unhealthy diet. Our conclusions at the end of this study is that the family with children in primary schools do not get involved in oral/dental health education.

    Cheating incidents in 2006-07 led U.S. dental schools to heighten their efforts to enhance the environment of academic integrity in their institutions. The aims of this study were to document the measures being used by U.S. dental schools to discourage student cheating, determine the current incidence of reported cheating, and make recommendations for enhancing a culture of integrity in dental education. In late 2014-early 2015, an online survey was distributed to academic deans of all 61 accredited U.S. dental schools that had four classes of dental students enrolled; 50 (82%) responded. Among measures used, 98% of respondents reported having policy statements regarding student academic integrity, 92% had an Honor Code, 96% provided student orientation to integrity policies, and most used proctoring of final exams (91%) and tests (93%). Regarding disciplinary processes, 27% reported their faculty members only rarely reported suspected cheating (though required in 76% of the schools), and 40% disseminated anonymous results of disciplinary hearings. A smaller number of schools (n=36) responded to the question about student cheating than to other questions; those results suggested that reported cheating had increased almost threefold since 1998. The authors recommend that schools add cheating case scenarios to professional ethics curricula; disseminate outcomes of cheating enforcement actions; have students sign a statement attesting to compliance with academic integrity policies at every testing activity; add curricular content on correct writing techniques to avoid plagiarism; require faculty to distribute retired test items; acquire examination-authoring software programs to enable faculty to generate new multiple-choice items and different versions of the same multiple-choice tests; avoid take-home exams when assessing independent student knowledge; and utilize student assessment methods directly relevant to clinical practice.

    The aims of this study were to analyze the administrative trends in U.S. dental schools at the beginning and end of a thirteen-year period and to identify the predictive factors for those changes. Administrative trends were measured by the difference in the number of major administrative positions for 1997 and 2010 reported in American Dental Education Association (ADEA) and American Dental Association (ADA) publications. Secondary measures (program length, student enrollment, and tuition) were also gathered. The mean numbers of administrative positions per school significantly increased over the study period, while the mean number of clinical science departments per school significantly decreased. The change in the number of directors was positively correlated with the change in student enrollment, but inversely correlated with the change in number of vice/associate/assistant deans. The change in the number of clinical science departments was positively correlated with changes in student enrollment and out-of-state tuition, but inversely correlated with the change in in-state tuition. The number of all departments per U.S. dental school significantly decreased in this period. The schools that had consolidation of clinical science departments were less likely to have increases in student enrollment and out-of-state tuition, but more likely to have increases in in-state tuition.

    Full Text Available Background: The school dental screening program has been in existence from the beginning of 20 th century. Its value in encouraging attendance among school children is not fully established. Aim: The aim was to determine the effectiveness of school dental screening on stimulating dental attendance rates among school children in Vikarabad town. Objectives: (a To compare the dental attendance rates between 6-9 and 10-13 years old age groups, among male and female school children in Vikarabad town. (b To identify the type of dental treatment received by the school children. Materials and Methods: A randomized controlled trial was conducted among school children aged 6-13 years old from 16 schools that were randomly selected and divided into two groups. Eight schools had a dental screening program (study group = 300 children and had blanket referral cards and 8 schools that did not have the intervention (control group = 300. The dental attendance rates were determined after 3 months of follow-up period by evaluating the blanket referral cards for the study group and by an oral questionnaire for the control group. Results: The dental attendance rate was 27% for the study group and 18% for the control group which is statistically significant. The attendance rate was higher among 10-13 years of children both in test group and control groups. Among the children who visited the dentist, 53% in the control group and 69% from the test group got simple amalgam and glass ionomer cement restorations. Conclusion: The dental attendance rates were improved following school dental screening.

    Academic dentistry, as a career track, is not attracting sufficient numbers of new recruits to maintain a corps of skilled dental educators. The Faculty Development Program (FDP) at the University of Texas Health Science Center at San Antonio Dental School received federal funds to institute a 7-component program to enhance faculty recruitment and retention and provide training in skills associated with success in academics including:(1) a Teaching Excellence and Academic Skills (TExAS)Fellowship, (2) training in research methodology,evidence-based practice research, and information management, (3) an annual dental hygiene faculty development workshop for dental hygiene faculty, (4) a Teaching Honors Program and Academic Dental Careers Fellowship to cultivate students' interest in educational careers, (5) an Interprofessional Primary Care Rotation,(6) advanced education support toward a master's degree in public health, and (7) a key focus of the entire FDP, an annual Career Transition Workshop to facilitate movement from the practice arena to the educational arm of the profession.The Career Transition Workshop is a cap stone for the FDP; its goal is to build a bridge from practice to academic environment. It will provide guidance for private practice, public health, and military dentists and hygienists considering a career transition into academic dentistry. Topics will be addressed including: academic culture, preparation for the academic environment,academic responsibilities, terms of employment,compensation and benefits, career planning, and job search / interviewing. Instructors for the workshop will include dental school faculty who have transitioned from the practice, military, and public health sectors into dental education.Objectives of the Overall Faculty Development Program:• Provide training in teaching and research skills,career planning, and leadership in order to address faculty shortages in dental schools and under representation of minority

    Changes in dental education towards integration of sciences and convergence of curricula have affected instruction in physics. Earlier studies of undergraduate curricula make possible comparisons in physics instruction. For this study, the websites of 245 European dental schools were explored, and information about the curriculum was found on 213 sites. Physics instruction in the form of a separate course was found in 63 percent of these schools, with eighty-two hours and 5.9 European Credit Transfer and Accumulation System (ECTS) credits on average. Physics integrated with other subjects or into modules was found in 19 percent of these schools. Half of these schools had on average sixty-one hours and 6.9 ECTS credits devoted to physics. Eighteen percent of the schools had no noticeable obligatory physics instruction, but in half of them physics was found to be required or accepted on admission, included in other subjects, or appeared as an elective course. In 122 dental schools, the extent of physics instruction was found to be between forty and 120 contact hours. Physics instruction has been reduced by up to 14 percent in the last fourteen years in the group of eleven countries that were members of the European Union (EU) in 1997, but by approximately 30 percent in last five years in the group of ten Accession Countries to the EU.

    The aims of this study were to assess curricular coverage of lesbian, gay, bisexual, and transgender (LGBT) content in U.S. and Canadian dental schools and U.S. dental hygiene programs, including hours of LGBT content, pedagogy used, and assessment methods, and to determine whether respondents perceived their institution's coverage as adequate. Data were collected from academic deans at 32 U.S. and two Canadian dental schools and from program directors at 71 U.S. dental hygiene programs (response rates 49%, 20%, 23%, respectively). The results showed that 29% of responding dental schools and 48% of responding dental hygiene programs did not cover LGBT content. Among the respondents, dental schools dedicated on average 3.68 hours and dental hygiene programs 1.25 hours in required settings to LGBT content. Lectures (dental schools 68%, dental hygiene programs 45%) and small group instruction (43%, 25%) were reported as the most common methodology used in teaching this content. Most of the responding dental schools and dental hygiene programs covered HIV (85%, 53%), oral disease risk (63%, 54%), and barriers to accessing health care for LGBT people (58%, 38%). Up to a third reported no need for coverage of topics such as sexual orientation (21%, 32%), coming out (29%, 37%), transitioning (29%, 38%), and sex reassignment surgery (32%, 35%). Assessment was through written examinations (41%, 30%) and faculty-observed patient interactions (21%, 23%); some respondents (20%, 33%) reported no assessment of learning outcomes. The most frequently endorsed strategies for increasing LGBT content were receiving curricular material focusing on LGBT-related health issues and health disparities and having trained faculty to teach LGBT content.

    This study investigated dental students' attitudes towards communication skills instruction and clinical application and explored the impact of a one-semester course and year in school on students' attitudes, measured by the Communication Skills Attitude Scale. Demographic characteristics and self-assessment of communication skills were also analyzed. The study employed a pretest-posttest survey design combined with cross-sectional data. Participants were first- and fourth-year students at a U.S. dental school. Out of a possible 120 students, 106 (fifty-seven D1 and forty-nine D4) participated in the pretest, an 88 percent response rate; out of a possible 121 students, 115 (fifty-seven D1 and fifty-eight D4) participated in the posttest, a 95 percent response rate. In the results, D4 students consistently demonstrated less positive attitudes towards communication skills instruction and more negative attitudes regarding the importance of interpersonal skills in clinical encounters than did their D1 counterparts. A single communications course had no discernible effect on attitudes or self-assessments for either cohort. Females reported more positive attitudes towards clinical application of interpersonal skills than did males. Gender significantly interacted with two demographic variables: primary language and parent as health care professional. Female children of health care professionals reported poorer attitudes towards clinical communication skills training and application than did their male counterparts. Generally, parental occupation in health care moderated the decrease in positive attitudes over time towards clinical usefulness of communication skills. The D4 students rated their communication skills higher than did the D1 students. Students who demonstrated more positive attitudes towards communication skills training and application were more likely to say their own skills needed improvement.

    Decades of research have shown that organizational climate has the potential to form the basis of workplace operations and impact an organization's performance. Culture is related to climate but is not the same. "Culture" is the broader term, defining how things are done in an organization, while "climate" is a component of culture that describes how people perceive their environment. Climate can be changed but requires substantial effort over time by management and the workforce. Interest has recently grown in culture and climate in dental education due to the humanistic culture accreditation standard. The aim of this study was to use corporate climate principles to examine how organizational culture and, subsequently, workplace operations can be improved through specific strategic efforts in a U.S. dental school. The school's parent institution initiated a climate survey that the dental school used with qualitative culture data to drive strategic planning and change in the school. Administration of the same survey to faculty and staff members three times over a six-year period showed significant changes to the school's climate occurred as a new strategic plan was implemented that focused on reforming areas of weakness. Concentrated efforts in key areas in the strategic plan resulted in measurable improvements in climate perception. The study discovered that culture was an area previously overlooked but explicitly linked to the success of the organization.

    Many graduating dentists leave dental school feeling that they are not prepared to start and run a dental practice. The aim of this pilot study was to explore the knowledge and perceptions dental graduates have in the area of practice management. A twenty-item survey was mailed in the fall of 2008 to nearly half of the University of Michigan dental school alumni who had graduated between the years of 1997 and 2007. Respondents were asked about their demographics, practice characteristics, and perceptions of knowledge/experience regarding practice management skills at the present time as well as at graduation. Data were analyzed using descriptive and inferential statistics. The majority of respondents were general practitioners (84 percent) aged thirty to thirty-nine practicing between six and ten years with practice incomes reported to be greater than $300,000 per year (79 percent). Most dentists reported being either an owner or co-owner of the practice (57 percent), and 33 percent reported being an associate in the practice. Upon graduation, 7 percent of the respondents felt that they had a strong knowledge of accounting or human resource issues; this perception increased to 47 percent at the present time. Similarly, less than 6 percent of respondents felt they understood issues pertaining to dental insurance upon graduation; this perception increased to 68 percent after having spent time in the workforce. In contrast to the large increase in knowledge/experience in business aspects of dentistry that had accrued since graduation, most alumni reported only a 7 percent increase in their knowledge of the legal aspects of dental practice. Results from this study indicate that interventions are needed to increase graduating dentists' knowledge of practice management and close the gap between their knowledge and its application in real life. The majority of alumni believed there is a need to improve the curriculum focused on these aspects of dental practice.

    The purpose of the present study is to investigate the prevalence of dental anomalies according to gender among children. This cross-sectional study was conducted a group of 600 children, of them 293 (48.8%) were males and 275 (45.8%) females which were taken with proper sampling technique. Type III clinical examination was done to know the prevalence of dental anomalies. The Statistical software namely SPSS version 16.0 was used for data analysis. Chi-square test was used at p value of 0.05 or less. Impactions (39.2%) were the most common anomaly in this study and most of the impacted teeth were related to maxilla. A significant difference was seen in case of hypodontia, microdontia and talons cusp according to gender in which first two anomalies were more among females and last one among males. Children with one dental anomaly were 25.8%, and 13.4% were having more than one. The percentage of dental anomalies were high specially impaction and rotated teeth. So these anomalies should be treated earlier to avoid further complications. How to cite this article: Kathariya MD, Nikam AP, Chopra K, Patil NN, Raheja H, Kathariya R.

    As part of the Basic Science Survey Series (BSSS) for Dentistry, members of the American Dental Education Association (ADEA) Physiology, Pharmacology, and Therapeutics Section surveyed course directors of basic pharmacology courses in North American dental schools. The survey was designed to assess, among other things, faculty affiliation and experience of course directors, teaching methods, general course content and emphasis, extent of interdisciplinary (shared) instruction, and impact of recent curricular changes. Responses were received from forty-nine of sixty-seven (73.1 percent) U.S. and Canadian dental schools. The findings suggest the following: 1) substantial variation exists in instructional hours, faculty affiliation, placement within curriculum, class size, and interdisciplinary nature of pharmacology courses; 2) pharmacology course content emphasis is similar among schools; 3) the number of contact hours in pharmacology has remained stable over the past three decades; 4) recent curricular changes were often directed towards enhancing the integrative and clinically relevant aspects of pharmacology instruction; and 5) a trend toward innovative content delivery, such as use of computer-assisted instruction applications, is evident. Data, derived from this study, may be useful to pharmacology course directors, curriculum committees, and other dental educators with an interest in integrative and interprofessional education.

    Links between the demanding nature of studies in the health sciences, students' personality traits and psychological distress have been well-established. While considerable amount of work has been done in medicine, evidence from the dental education arena is sparse and data from Latin America are lacking. The authors conducted a large-scale investigation of psychological distress among dental students in Colombia and sought to determine its curriculum and student-level correlates. The Spanish version of the Derogatis' Symptoms Checklist Revised (SCL-90-R) was administered to all students officially registered and attending classes or clinics in 17 dental schools in 4 geographic districts of Colombia between January and April 2012. Additional information was collected on participants' socio-demographic information and first career choice, as well as school's characteristics such as class size. The Global Severity Index (GSI) score, a measure of overall psychological distress, served as the primary analytical endpoint. Analyses relied on multilevel mixed-effects linear and log-binomial regression, accounting for study design and sample characteristics. A total of 5700 dental students completed the survey, a response rate of 67%. Pronounced gradients were noted in the association between socio-economic status and psychological distress, with students in higher strata reporting fewer problems. After adjustment for all important covariates, there was an evident pattern of increasing psychological distress corresponding to the transition from the didactic, to the preclinical and clinical phases of training, with few differences between male and female students. Independent of other factors, reliance on own funds for education and having dentistry as the first career choice were associated with lower psychological distress. Levels of psychological distress correlated with students' socio-economic and study-level characteristics. Above and beyond the influence of person

    Comprehensive assessment of students' academic performance plays an important role in educational planning. The aim of this study was to investigate variables that influence student's performance in a retrospective sample including all undergraduate students who entered in a Brazilian dental school, in a 20-year period between 1984 and 2003 (n=1182). Demographic and educational variables were used to predict performance in the overall curriculum and course groups. Cluster analysis (K-means algorithm) categorized students into groups of higher, moderate or lower performance. Clusters of overall performance showed external validity, demonstrated by Chi-square test and ANOVA. Lower performance groups had the smallest number of students in overall performance and course groups clusters, ranging from 11.8% (clinical courses) to 19.2% (basic courses). Students' performance was more satisfactory in dental and clinical courses, rather than basic and non-clinical courses (pstudent's performance was predicted by lower time elapsed between completion of high school and dental school admission, female gender, better rank in admission test, class attendance rate and student workload hours in teaching, research and extension (R(2)=0.491). Findings give evidence about predictors of undergraduate students' performance and reinforce the need for curricular reformulation focused on with improvement of integration among courses.

    As the U.S. population continues to become more diverse, there has been a movement toward the recruitment of more diverse students into the dental profession. The purpose of this study was to assess the current and historical trends in diversity among dental school applicants and enrollees at a new dental institution, the University of Nevada, Las Vegas, School of Dental Medicine (UNLV-SDM). Applicant and enrollment data for the first four cohorts, sorted by gender and ethnicity, were retrieved and summarized by the Office of Admissions and Student Affairs at UNLV-SDM. The principal findings of this analysis revealed enrollment of females at UNLV-SDM was relatively consistent during this time interval, although significantly lower than the U.S. average of all dental schools. The enrollment of minorities at UNLV-SDM, however, was consistent and comparable to the U.S. average, although these percentages were disproportionately smaller than the percentage of minorities in the general population. Based upon these findings, a new model for outreach and recruitment of females and minorities was recently created, based in part upon evidence of successful strategies by dental educators at other institutions, in order to increase the enrollment of female and underrepresented minority students.

    Libraries have an exceptional place in the history, culture, education and scientific life of a nation. They collect all aspects of our linguistics and literacy, all out theoretical assumptions as well as all the results of experience and practice. The importance of a library is not mirrored only in the national and historical role and heritage, but in a more permanent, informational role, since a modern library must, above all, be an effective information system. Since a library of a university operates as a part of its matrix, it is easily shadowed by other forms of educational and scientific infrastructure. 50(th) anniversary of the Central Dental Library of the School of Dental Medicine University of Zagreb is an excellent opportunity to make a call to the institution and public to its unique and irreplaceable role.

    The Internet represents the central communication medium in higher education. University applicants, students, teachers and scientists use the Internet when seeking information on medicine. The homepages of dental schools are not just sources of information, but also a means of presenting the school. No comparative studies have been undertaken concerning the content and extent of their Internet sites so far. Based on the literature and assessments of medical school websites, 136 criteria were defined within the setting of a Delphi procedure and drawn upon for a standardised evaluation of the websites of all 30 German dental schools. Structure and extent of the content of the websites were evaluated. Possible influencing factors, such as financial resources and number of applicants, were investigated. The results yielded by the homepages varied considerably. The best Internet site received 84% of the possible points, the poorest 38%. On average, 62% of the criteria were fulfilled. Influencing factors, such as the amount of funding by the particular state government, could not be detected. Two-thirds of the dental schools addressed students, three-fourth teachers and scientists as target groups. More than 50% did not address applicants. Specific requirements regarding barrier-free accessibility of information were hardly met. Individual faculties already have homepages of a high quality; for others, there is a need for improvement. General recommendations for university websites should be discussed at the European level to ensure a uniform standard of quality. The criteria presented here offer faculties the possibility to reflect upon their own Internet sites. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    healthy dietary habits are considered to improve oral health and tooth quality. Caries treatment comprises tooth restoration with dental composites and sealants, almost all (> 90%) of which contain bisphenol A (BPA). Study hypotheses were: a) breakfast and oral hygiene habits are important factors in dental caries development; and b) dental caries treatment with epoxy-resins entails a risk of oral exposure to monomers migrating from the polymeric material. We evaluated caries in the teeth of a Spanish school population and determined the percentage treated with dental composites. to relate consumption of breakfast components and oral hygiene habits to dental caries and determine the presence of sealants/composites as potential sources of BPA exposure. subjects: 582 schoolchildren from Granada city (Southern Spain) aged 7 yrs; mean (SD) of 7.55 (0.64) yrs. caries was detected in 21.7% of their teeth. Mean breakfast quality index (BQI) score, based on nutritional questionnaires, was 5.18 (1.29). Breakfast with foods rich in simple sugars representing > 5% of total daily energy was consumed by 24% of the population and was significantly associated with caries frequency in binary logistic regression analysis. Biscuit consumption was reported by 35.8% and significantly associated with caries frequency. Breakfast intake of bakery products/ cereals and of dairy products showed a significant inverse association with caries frequency. No significant relationship was observed between caries and BQI score or oral hygiene factors. further research is required to elucidate the role of diet in caries and the associated risk of exposure to estrogenic xenobiotics such as BPA.

    The purpose of this investigation was to examine the drivers of patient retention at dental school clinics from a services marketing perspective. An analysis of patient characteristics at Virginia Commonwealth University School of Dentistry, screened between August 2010 and July 2011 (N=3604), was performed using descriptive statistics, cross-tabulations, and a binary logistic regression. The main findings were that 42 percent of patients in the study were retained and that no response to communication efforts (36 percent) and financial problems (28 percent) constituted the most common reasons for non-retention. Older age, having insurance, and living within a sixty-mile radius were significant drivers of retention (pskills to better service them, and consequently increasing retention. This will lead to providing a continuum of care and student education and to ensuring the sustainability and quality of the school's educational programs.

    Full Text Available Polyetheretherketone (PEEK is a semi-crystalline linear polycyclic thermoplastic that has been proposed as a substitute for metals in biomaterials. PEEK can also be applied to dental implant materials as a superstructure, implant abutment, or implant body. This article summarizes the current research on PEEK applications in dental implants, especially for the improvement of PEEK surface and body modifications. Although various benchmark reports on the reinforcement and surface modifications of PEEK are available, few clinical trials using PEEK for dental implant bodies have been published. Controlled clinical trials, especially for the use of PEEK in implant abutment and implant bodies, are necessary.

    The Association for Dental Education in Europe (ADEE) makes recommendations regarding the skills graduates of European dental schools need to achieve and advises dental schools regarding necessary changes to be made to the curriculum. In 2010 to 2011, a survey was conducted in German-language dental schools to validate the curricula and goals of preclinical prosthodontic programs with regard to laboratory work. The survey was mailed to the course instructors of the preclinical programs at 37 dental schools. Of these, 35 schools returned the completed survey, resulting in a response rate of 95%. Bent wire, wax-up exercises, metal-ceramic single crowns, fixed dental prostheses, cast metal single crowns, temporary removable dental prostheses, and full dentures were part of the dental laboratory work at most schools; however, most instructors considered laboratory work as less important, and there were few similarities among the programs in this area. According to the instructors responsible for preclinical education, honing of fine motor skills, realistic self-assessment, and the ability to work independently were the main goals of the programs. The results of this survey show that with regard to laboratory work, there were more differences than similarities among preclinical prosthodontic programs at German-language dental schools, contrary to the recommendations of the ADEE. These findings should be taken into account when program reforms are planned. © 2013 by the American College of Prosthodontists.

    Full Text Available Abstract Background Dental caries, dental pain and reported oral problems influence people's oral quality of life and thus their perceived need for dental care. So far there is scant information as to the psychosocial impacts of dental diseases and the perceived treatment need in child populations of sub-Saharan Africa. Objectives Focusing on primary school students in Kilwa, Tanzania, a district deprived of dental services and with low fluoride concentration in drinking water, this study aimed to assess the prevalence of dental pain and oral impacts on daily performances (OIDP, and to describe the distribution of OIDP by socio-demographics, dental caries, dental pain and reported oral problems. The relationship of perceived need estimates with OIDP was also investigated. Methods A cross-sectional study was conducted in 2008. A total of 1745 students (mean age 13.8 yr, sd = 1.67 completed an extensive personal interview and under-went clinical examination. The impacts on daily performances were assessed using a Kiswahili version of the Child-OIDP instrument and caries experience was recorded using WHO (1997 criteria. Results A total of 36.2% (41.3% urban and 31.4% rural, p Conclusion Substantial proportions of students suffered from untreated dental caries, oral impacts on daily performances and perceived need for dental care. Dental pain and reported oral problems varied systematically with OIDP across the eight impacts considered. Eating and tooth cleaning problems discriminated between subjects who perceived need for dental treatment and those who did not.

    The current position of practical preclinical and clinical training in dento-maxillo-facial radiography for dental students and oral hygiene students in South Africa is reviewed. Special attention is given to factors in methodology which have an influence on radiation protection. Results indicate that there is a fairly high degree of standardization in dento-maxillo-facial radiography instruction in South Africa. The preference for the lead-lined or shielded open-ended cones is in keeping with the tenets of radiation protection. The use of pointed cones for intraoral radiography is not a good choice, as this causes scatter radiation. The wide use of the Rinn XCP(R) filmholding device in South African dental schools for the parallelling technique lessens the chance of cone cutting, and hence reduces the likelihood of needing to reexpose the patient due to that technical error. Additionally, the parallelling technique allows a more accurate assessment of alveolar bone loss from periodontal disease, and allows a better judgement of the relationship between the roots of maxillary teeth and the floor of the maxillary sinus, than does the bisecting angle technique. During the past decade, fiarly consistent parameters have been developed in dento-maxillo-facial radiography concerning preclinical and clinical training of dental and oral hygiene students [af

    The authors conducted a systematic review to determine: a) What dental schools and dental hygiene programs are doing to promote knowledge and skills related to addressing childhood obesity and to reduce consumption of sugar-sweetened beverages (SSBs) and b) What else these schools and programs could do to better equip future oral health professionals to address childhood obesity and reduce consumption of SSBs. The authors searched PubMed, Scopus, Education Full Text (EBSCOHost), and ERIC (EBSCOHost) to identify peer-reviewed publications reporting on obesity or dietetic-related curricula in dental and dental hygiene education within the last 20 years. Three studies met inclusion and exclusion criteria. Outcomes of the identified studies were abstracted and summarized independently by two investigators. The first study describes a 2009 survey of pediatric dentistry residents. Approximately, half had received formal training yet they lacked essential knowledge or skills for managing children who were obese. The second study describes nutrition-related coursework offered in the second year of a predoctoral dental school curriculum in Saudi Arabia, and the third study reports on the development of an "oral health rotation" dietetic internship in a pediatric dentistry clinic, in the context of interprofessional education (IPE). Evidence of dental schools' and dental hygiene programs' efforts to address obesity and SSB consumption in children in their curricula is scant, while Commission on Dental Accreditation standards make sporadic mentions of diet and nutrition. Opportunities exist to leverage existing resources and innovative, experiential approaches, including IPE, to formally, and effectively address this important issue in predoctoral oral health education. © 2017 American Association of Public Health Dentistry.

    The dearth of dental faculty members is a widely known problem that is exacerbated in countries that are attempting to begin dental education programs. This collaboration between Kwame Nkrumah University of Science and Technology and the University of Michigan investigated if dental students who have just started their clinical dental education can learn the knowledge and skills required for identifying and restoring cavitated caries lesions through compact course delivery. There were three instructional blocks: 1) didactic seminar; 2) seminar, simulated hands-on skills instruction, and clinical observation/assisting with treatment of schoolchildren; and 3) seminar, simulated skills training, and application to schoolchildren. Each dental student completed a questionnaire measuring knowledge and perceptions of knowledge, experience, and confidence at five points in time. The dental students' knowledge increased significantly as well as their perceived knowledge, experience, and confidence (p<0.0001). In general, the students showed proficiency in delivering simple treatments. The project showed that an integrated compact course delivery model may assist emerging dental schools to cope with the challenging shortage of resident faculty members.

    In this study, 491 dental students at one dental school in the United States and one in Bulgaria were surveyed to assess their perceptions about the mission of dental schools to advance global dentistry and philanthropy. The study included questions about prior involvement in charitable dental missions. Many respondents felt that their dental school does not advance global dentistry nor adequately teaches students the virtues of philanthropy and volunteerism. The majority agreed, however, that dental schools have a moral obligation to raise the level of oral health care worldwide and help underserved communities access basic dental care. They reported that an opportunity to spend a semester at a foreign dental school would enhance their dental education in ways that are not presently fulfilled; help them better understand cultural diversity; and teach them about philanthropy and volunteerism. In their opinion, international exchange programs that provide clinical rotations and field experiences in economically challenged and underserved areas of the world would a) foster the global advancement of dentistry; b) promote an appreciation for cultural diversity and socioeconomic disparity in the communities that graduates will be serving; and c) teach students the virtues of philanthropy and volunteerism. This study may contribute to understanding factors affecting student involvement in programs to advance global dentistry.

    The purpose of this study was to identify the status of pre-doctoral geriatric dentistry education among all Chilean dental schools. Chile is one of the most rapidly ageing countries in Latin America. Consequently, specific knowledge and training on the needs of elderly populations need to be emphasised in dental schools. The current extent and methods of teaching geriatric dentistry among the dental schools in Chile are unknown. A web-based questionnaire was developed and sent to all 19 Chilean dental schools to identify which schools had a formal programme on geriatric dentistry and ask about their format, content and type of training of the faculty who taught in the programmes. Data were analysed, and a comparison was made among the schools. Sixteen (84%) of the participant schools reported teaching at least some aspects of geriatric dentistry, using various methodologies, but only 7 (37%) had specific courses. Of those schools reporting a didactic content on geriatric dentistry, 71% included clinical training, either in the school's dental clinics or in an extramural service. Contents mostly included demographics of ageing, theories of ageing and medical conditions. More than half of the faculty (57%) stated that they had formal training in geriatric dentistry, 43% were trained in prosthodontics, public health or other areas. Although most dental schools taught geriatric dentistry, only some had a specific course. Most schools with formal courses followed the international curriculum guidelines for geriatric dentistry. © 2014 John Wiley & Sons A/S and The Gerodontology Association.

    Dental schools need to produce graduates who are adequately prepared to respond to the complex needs and challenges of the increasingly diverse and interconnected world in which they will practice dentistry. To enhance discussions about the coverage of global oral health competencies in dental education, the aims of this study were to assess how global health education is currently incorporated into predoctoral dental training in the U.S. and which global oral health competencies are being covered. Surveys were emailed to all 64 accredited U.S. dental schools during the 2015-16 academic year. Respondents from 52 schools completed the survey (response rate 81%). The results showed that social determinants of oral diseases and conditions, how to identify barriers to use of oral health services, and how to work with patients who have limited dental health literacy were covered in the greatest number of responding schools' curricula. Key areas of global health curricula that were covered rarely included global dental infrastructure, data collection design, and horizontal and vertical programming approaches to health improvement. Despite current dialogue on the addition of global oral health competencies to dental curricula, only 41% of the responding schools were currently planning to expand their global oral health education. Based on these results, the authors conclude that it may be most feasible for dental schools to add recommended global oral health competencies to their curricula by incorporating didactic content into already established courses.

    Advances in digital impression technology and manufacturing processes have led to a dramatic paradigm shift in dentistry and to the widespread use of computer-aided design/computer-aided manufacturing (CAD/CAM) in the fabrication of indirect dental restorations. Research and development in materials suitable for CAD/CAM applications are currently the most active field in dental materials. Two classes of materials are used in the production of CAD/CAM restorations: glass-ceramics/ceramics and resin composites. While glass-ceramics/ceramics have overall superior mechanical and esthetic properties, resin-composite materials may offer significant advantages related to their machinability and intra-oral reparability. This review summarizes recent developments in resin-composite materials for CAD/CAM applications, focusing on both commercial and experimental materials. © International & American Associations for Dental Research.

    Children in a German region took part in regular toothbrushing with fluoride gel during their time in primary school after having received a preventive program in kindergarten. The study aimed at determining the dental health of the students as a function of prevention in kindergarten and at school while taking into account their socioeconomic status and other confounders. The subjects were in six groups: groups 1 and 2, intensive prevention in kindergarten with and without fluoride gel at school; groups 3 and 4, basic prevention in kindergarten with and without fluoride gel at school; groups 5 and 6, no organized prevention in kindergarten with and without fluoride gel at school. Two dental examinations were performed for assessing caries experience and calculating caries increment from second grade (7-year-olds) to fourth grade (9-year-olds). A standardized questionnaire was used to record independent variables. To compare caries scores and preventive measures of various subgroups, non-parametric tests and a binary logistic regression analysis were performed. A significant difference was found in the mean decayed, missing, and filled tooth/teeth (DMFT) depending on socioeconomic status (no prevention in kindergarten, fluoride gel at school in children with low SES: DMFT = 0.47 vs. DMFT = 0.18 in children with high SES; p = 0.023). Class-specific differences were no longer visible among children who had taken part in an intensive preventive program combining daily supervised toothbrushing in kindergarten and application of fluoride gel in school. Early prevention, focusing on professionally supported training of toothbrushing in kindergarten and at school, has a positive effect on dental health and is able to reduce class-specific differences in caries distribution. Early training of toothbrushing and fissure sealing of first permanent molars are the most important factors for the dental health of primary school children.

    Meeting the oral health care needs of the growing population of people with special health care needs (SHCN) starts with dental students' acquisition of sound knowledge and development of clinical competence at the predoctoral level. The aim of this study was to review the level of undergraduate education in Special Needs Dentistry (SND) in Malaysian and Australian dental schools. The deans of all six Malaysian public dental schools and eight of nine Australian dental schools participated in a postal survey on current undergraduate didactic and clinical training in SND at their institutions. The results showed the number of dental schools in Malaysia with teaching in SND as a specific discipline was relatively low compared to that of Australia. However, a high percentage of Malaysian and Australian dental schools reported incorporating teaching of SND into pediatric dentistry (83.3 percent vs. 75 percent), oral medicine/oral pathology (66.7 percent vs. 75 percent), and oral surgery (66.7 percent vs. 25 percent). Most respondents said their school delivered SND clinical training in dental school clinics, hospital-based settings, and residential aged care facilities. Respondents in both countries viewed lack of faculty expertise as the greatest barrier to providing SND education. The study provides valuable information that can direct SND curriculum development in the two countries.

    Since social media sites began to appear in the 1990s, their popularity has increased dramatically, especially among younger individuals. With this widespread use of social media, institutions of higher education are finding the need to implement social media policies. The purpose of this study was to gather information from accredited U.S. dental schools on their social media policies. A survey sent to academic deans asked questions related to social media policies and violations of policies. The survey yielded a 35.9 percent (n=23) response rate. Social media policies at the university level were reported by 47.8 percent (n=11) of respondents, and 34.8 percent (n=8) had social media policies specifically in the dental school. Schools that had an institutional social media policy were more likely to have a social media policy in the dental school (p=0.01), and dental schools were more likely to have a policy if the academic dean had been in the position less than five years (p=0.01). All twenty-three responding dental schools have official social media pages. Dental educators and administrators may want to look for opportunities to raise awareness of social media professionalism in their dental schools.

    2015-08-01

    A lack of curriculum time devoted to teaching dental students about the needs of lesbian, gay, bisexual, and transgendered (LGBT) health care patient needs and biases against LGBT students and faculty have been reported. Understanding dental school administrators' attitudes about LGBT students' needs might provide further insight into these long-standing issues. The aims of this study were to develop a survey to assess dental administrators' attitudes regarding the support services they believe LGBT-identified students need, to identify dental schools' current diversity inclusion policies, and to determine what types of support dental schools currently provide to LGBT students. A survey developed with the aid of a focus group, cognitive interviewing, and pilot testing was sent to 136 assistant and associate deans and deans of the 65 U.S. and Canadian dental schools. A total of 54 responses from 43 (66%) schools were received from 13 deans, 29 associate deans, and 11 assistant deans (one participant did not report a position), for a 40% response rate. The findings suggest there is a considerable lack of knowledge or acknowledgment of LGBT dental students' needs. Future studies are needed to show the importance of creating awareness about meeting the needs of all dental student groups, perhaps through awareness campaigns initiated by LGBT students.

    The aim of this cross-sectional study was to assess awareness and attitudes related to tooth erosion among dental students, patients, and faculty members in a Brazilian dental school. Data were collected by means of a self-applied questionnaire that was distributed among 298 participants. The response rate was 89.6 percent. Chi-square and Fisher's exact tests were used for statistical analysis (perosion (72.9 percent), with lower percentages among the patients (perosion (p=0.004). Almost 30 percent of the students did not know if they had had a patient with erosion, and 73.1 percent reported they were not advised by their clinical supervisor to examine their patients for tooth erosion (p=0.138). Concerning the faculty, 23.6 percent of them along with 61.5 percent of the students did not feel prepared to diagnose the condition (perosion (89.6 percent). Knowledge about tooth erosion was not as widely evident as it should be in this sample, suggesting the need for better understanding and communication in this important area of oral health care.

    Full Text Available Background and Aims: Dental erosion refers to the loss of tooth structure by being scratched chemically without bacterial involvement which needs to care about due to its prevalence and treatment problems. This study was designed with the aim of evaluation of the frequency of dental erosion and its causing factors in patients referring to yazd dental school in 2012-2013. Materials and Methods: In this cross-sectional study, 400 patients referring to yazd dental school were randomly selected. All of their teeth were evaluated in three surfaces (buccal, lingual and occlusal. The BEWE score was used for classification the extent of damages. Also, patients were given a questionnaire that included patient demographic information and questions to investigate the causes of dental erosion. Data were analyzed using SPSS version 17 and Mann-Whiney, Fisher exact, and Chi-square tests. Results: In this study, 138 men and 261 women were participated with the mean age of 33.26±10.83. 84 persons (21.1% had erosion. There was a direct and significant relationship between the dental erosion and patient's age (P >0.001. Also, there was a direct relationship between the dental erosion and reflux and consumption of lemon and pickle, beverages, soft beer and juice (P>0.001. Conclusion: Consumption of lemon and pickle, beverages, soft beer and juice increases the risk of erosion. Considering the prevalence of dental erosion in about 21% of patients, it is necessary to pay more attention to the knowledge of the causes of erosion and reduction strategies of it.

    The number of U.S. and Canadian dental schools offering programs for dentists with degrees from other countries leading to the D.D.S. or D.M.D. degree has increased recently. This fact, along with the diversity of educational systems represented by candidates for these programs, increases the importance of identifying valid admissions predictors of success in international dental student programs. Data from 148 students accepted into the international dental studies program at the University of the Pacific from 1994 through 2004 were analyzed. Dependent variables were comprehensive cumulative GPA at the end of both the first and second years of the two-year program. The Test of English as a Foreign Language (TOEFL) and both Parts I and II of the National Board Dental Examination (NBDE) were significant positive predictors of success. Performance on laboratory tests of clinical skill in operative dentistry and in fixed prosthodontics and ratings from interviewers were not predictive of overall success in the program. Although this study confirms the predictive value of written tests such as the TOEFL and NBDE, it also contributes to the literature documenting inconsistent results regarding other types of predictors. It may be the case that characteristics of individual programs or features of the applicant pools for each may require use of admissions predictors that are unique to schools.

    An study of the damage induced in dental materials and model multilayer systems by masticatory contact stresses, simulated by hertz ian indentation test, have been performed. In particular, the nature of induced damage has been identified, and quantified from stress-strain curves and critical loads for yielding or crack initiation. For multilayer systems, test have been numerically simulated using finite element techniques (FEM). FEM simulations complement indentation test, allowing to justify the observed fracture modes from calculated stress fields. Practical implications can be derived from our results, relevant to the design of multilayer structures tolerant to contact damage. (Author) 34 refs

    Dental caries is one of the most common diseases affecting children in Saudi Arabia despite the availability of free dental services. School-based dental screening could be a potential intervention that impacts uptake of dental services, and subsequently, dental caries' levels. The purpose of this study is to evaluate the effectiveness of two alternative approaches for school-based dental screening in promoting dental attendance and reducing untreated dental caries among primary schoolchildren. This is a cluster randomised controlled trial comparing referral of screened-positive children to a specific treatment facility (King Saud University Dental College) against conventional referral (information letter advising parents to take their child to a dentist). A thousand and ten children in 16 schools in Riyadh, Saudi Arabia, will be recruited for the trial. Schools (clusters) will be randomly selected and allocated to either group. Clinical assessment for dental caries will be conducted at baseline and after 12 months by dentists using the World Health Organisation (WHO) criteria. Data on sociodemographic, behavioural factors and children's dental visits will be collected through structured questionnaires at baseline and follow-up. The primary outcome is the change in number of teeth with untreated dental caries 12 months after referral. Secondary outcomes are the changes in the proportions of children having untreated caries and of those who visited the dentist over the trial period. This project should provide high level of evidence on the clinical benefits of school dental screening. The findings should potentially inform policies related to the continuation/implementation of school-based dental screening in Saudi Arabia. ClinicalTrials.gov , ID: NCT03345680 .

    This review of U.S. dental schools' clinical curricula suggests that the basic structure of clinical education has not changed significantly in the past 60 years, although important developments include the introduction of competency-based education and community-based clinical education. Most dental schools still have a two-year preclinical curriculum and a two-year clinical curriculum, and most schools still operate a large clinical facility where students receive the bulk of their clinical education and assessment for graduation. In those clinics, dental students are the main providers of patient treatment, with faculty serving in supervisory roles. In addition, a major portion of the entire dental curriculum continues to be dedicated to student education on the restoration of a single tooth or replacement of teeth. This article was written as part of the project "Advancing Dental Education in the 21 st Century."

    School-based dental programs target high-risk communities and reduce barriers to obtaining dental services by delivering care to students in their schools. We describe the evaluation of a school-based dental program operating in Chelsea, a city north of Boston, with a low-income and largely minority population, by comparing participants' oral health to a Massachusetts oral health assessment. Standardized dental screenings were conducted for students in kindergarten, third, and sixth grades. Outcomes were compared in bivariate analysis, stratified by grade and income levels. A greater percentage of Chelsea students had untreated decay and severe treatment need than students statewide. Yet, fewer Chelsea third graders had severe treatment need, and more had dental sealants. There was no significant difference in the percentage of Chelsea students having severe treatment need or dental sealants by income level. Students participating in our program do not have lower decay levels than students statewide. However, they do have lower levels of severe treatment need, likely due to treatment referrals. Our results confirm that school-based prevention programs can lead to increased prevalence of dental sealants among high-risk populations. Results provide support for the establishment of full-service school-based programs in similar communities. © 2017, American School Health Association.

    Healthy teeth and oral tissues and the need for oral health care are important for any section of society. Dental caries is an infectious microbial disease of multifactorial origin in which diet, host, and microbial flora interacts over a period of time in such a way so as to encourage demineralization of the tooth enamel with resultant caries formation. Dental caries, the product of man's progress towards civilization, has a very high morbidity potential and thus, is coming into focus of the mankind. To assess the prevalence of dental caries among 12-15 year old government and private school children of Bharatpur city. This was a cross-sectional study carried out on total 1400 school children, of which 700 school children were from government schools and 700 were from private schools. Simple random sampling methodology was used to select the sample. The subjects were examined for dental caries according to WHO 1997 assessment form. Significant Caries Index was also used to assess the prevalence of dental caries. The prevalence of dental caries was found higher among government school children, that is, 53%, when compared to private school children, that is, 47% and this difference was found to be statistically significant. The mean decayed, missing, and filled teeth were found to be higher in government school children (7.61 ± 2.86) as compared to private school children (4.76 ± 2.42). Dental caries was found to be the major public health problems among both the government and private school children of Bharatpur city, which need immediate attention. Regular dental checkups and practice of routine oral hygiene procedures will enable them to lead a healthier life.

    Stem cells are pluripotent cells, having a property of differentiating into various types of cells of human body. Several studies have developed mesenchymal stem cells (MSCs) from various human tissues, peripheral blood and body fluids. These cells are then characterized by cellular and molecular markers to understand their specific phenotypes. Dental pulp stem cells (DPSCs) are having a MSCs phenotype and they are differentiated into neuron, cardiomyocytes, chondrocytes, osteoblasts, liver cells and β cells of islet of pancreas. Thus, DPSCs have shown great potentiality to use in regenerative medicine for treatment of various human diseases including dental related problems. These cells can also be developed into induced pluripotent stem cells by incorporation of pluripotency markers and use for regenerative therapies of various diseases. The DPSCs are derived from various dental tissues such as human exfoliated deciduous teeth, apical papilla, periodontal ligament and dental follicle tissue. This review will overview the information about isolation, cellular and molecular characterization and differentiation of DPSCs into various types of human cells and thus these cells have important applications in regenerative therapies for various diseases. This review will be most useful for postgraduate dental students as well as scientists working in the field of oral pathology and oral medicine. PMID:26131314

    To discuss the development and current status of application of nonlinear finite element method (FEM) in dentistry. The literature was searched for original research articles with keywords such as nonlinear, finite element analysis, and tooth/dental/implant. References were selected manually or searched from the PUBMED and MEDLINE databases through November 2007. The nonlinear problems analyzed in FEM studies were reviewed and categorized into: (A) nonlinear simulations of the periodontal ligament (PDL), (B) plastic and viscoelastic behaviors of dental materials, (C) contact phenomena in tooth-to-tooth contact, (D) contact phenomena within prosthodontic structures, and (E) interfacial mechanics between the tooth and the restoration. The FEM in dentistry recently focused on simulation of realistic intra-oral conditions such as the nonlinear stress-strain relationship in the periodontal tissues and the contact phenomena in teeth, which could hardly be solved by the linear static model. The definition of contact area critically affects the reliability of the contact analyses, especially for implant-abutment complexes. To predict the failure risk of a bonded tooth-restoration interface, it is essential to assess the normal and shear stresses relative to the interface. The inclusion of viscoelasticity and plastic deformation to the program to account for the time-dependent, thermal sensitive, and largely deformable nature of dental materials would enhance its application. Further improvement of the nonlinear FEM solutions should be encouraged to widen the range of applications in dental and oral health science.

    Tooth hypersensitivity is a growing problem affecting both the young and ageing population worldwide. Since an effective and permanent solution is not yet available, we propose a new methodology for the restoration of dental enamel using femtosecond lasers and novel calcium phosphate biomaterials. During this procedure the irradiated mineral transforms into a densified layer of acid resistant iron doped β-pyrophosphate, bonded with the surface of eroded enamel. Our aim therefore is to evaluate this densified mineral as a potential replacement material for dental hard tissue. To this end, we have tested the hardness of β-pyrophosphate pellets (sintered at 1000 °C) and its mineral precursor (brushite), the wear rate during simulated tooth-brushing trials and the cytocompatibility of these minerals in powder form. It was found that the hardness of the β-pyrophosphate pellets is comparable with that of dental enamel and significantly higher than dentine while, the brushing trials prove that the wear rate of β-pyrophosphate is much slower than that of natural enamel. Finally, cytotoxicity and genotoxicity tests suggest that iron doped β-pyrophosphate is cytocompatible and therefore could be used in dental applications. Taken together and with the previously reported results on laser irradiation of these materials we conclude that iron doped β-pyrophosphate may be a promising material for restoring acid eroded and worn enamel. - Highlights: • A novel procedure for the restoration of dental enamel is introduced. • Fe-doped ß-pyrophosphate is evaluated as potential biomaterial for enamel restoration. • Fe-doped ß-pyrophosphate found to have the same hardness as natural enamel and dramatically lower wear rate. • Cytotoxicity and genotoxicity tests suggest that Fe-doped ß-pyrophosphate is safe for dental applications.

    This cross-sectional study evaluated the prevalence of dental fear and associated factors in schoolchildren aged 8 to 12 years old, in Pelotas, southern Brazil. Schoolchildren enrolled in 20 public and private schools were selected using a multi-stage sample design. Sociodemographic characteristics, children's dental visit and oral hygiene habits were assessed by questionnaires. The Dental Anxiety Question was used to measure dental fear prevalence. Children's clinical examination evaluated presence of dental caries (DMFT/dmft index) and gingival bleeding. Data were analyzed using Poisson regression with robust variance (prevalence ratio; 95% confidence interval). One thousand two hundred and two children were included. Dental fear prevalence was 24.6%. After the adjustment, girls [PR=1.71 (CI 95%: 1.31-2.22)], children from poorer families [PR=1.96 (CI 95%: 1.36-2.83)], those who had decayed teeth (D/d index>0)[PR=1.32 (CI 95%: 1.01-1.72), and who had never been at the dentist [PR=1.85 (CI 95%: 1.42-2.41) remained significantly associated with dental fear. The prevalence of dental fear indicates that it is a common problem among schoolchildren. Early dental care and dental caries prevention are important factors to prevent dental fear.

    In today's dental education environment, a humanistic culture is an expectation for all U.S. dental schools, codified in 2013 by its inclusion in the Commission on Dental Accreditation's standards for accreditation. The University of the Pacific Arthur A. Dugoni School of Dentistry has made an active commitment to humanism since the mid-1970s. The aim of this study was to determine how well the school's students and faculty and staff members perceived the school was living up to its formal aspirational values and who was benefitting from the humanistic culture. Using an electronic survey, data were collected from a total of 195 students, faculty members, and staff members in 2014. Respondents were 15% of the 492 full- and part-time faculty members; 9% of the total student population of 540; and 29% of 255 staff members. In the responses, humanism was described as manifest by attributes such as caring, understanding, respect, and compassion. Although the findings confirmed the value of a humanistic culture, some portions of the school's formal definition and goals, such as good work ethic, professional responsibility, high ethical standards, increasing independence, and attainment of competence, appeared less frequently in responses. Authentic assessment of institutional culture proved challenging. Focus groups offered additional ways to assess how effectively the school lives its core value of humanism. There was recognition that more varied, robust methods were needed to assess institutional alignment with stated goals for a humanistic learning environment.

    This paper presents a new approach to sharpen blurred edge features in scanned tooth preparation surfaces generated by structured-light scanners. It aims to efficiently enhance the edge features so that the embedded feature lines can be easily identified in dental CAD systems, and to avoid unnatural oversharpening geometry. We first separate the feature regions using graph-cut segmentation, which does not require a user-defined threshold. Then, we filter the face normal vectors to propagate the geometry from the smooth region to the feature region. In order to control the degree of the sharpness, we propose a feature distance measure which is based on normal tensor voting. Finally, the vertex positions are updated according to the modified face normal vectors. We have applied the approach to scanned tooth preparation models. The results show that the blurred edge features are enhanced without unnatural oversharpening geometry.

    The expected length of service and reasons for fixed dental prostheses (FDPs) replacement are a frequent inquiry by patients while the answers were mainly based on studies reports that was conducted outside the middle east region. This clinical and radiographic survey was constructed to assess and survey clinically and radiographically the reasons of replacement of metal-ceramic fixed dental prostheses, amongst patients reporting at dental school in Taibah University. Between January and May 2016, 151 patients were recruited for this study. Interview (include questions pertained to the length of service of the prosthesis, the nature of complaint as told by patient in her own words), clinical examination, intra-oral photographs, and periapical radiographs, were done by the researchers. The parameters assessed were secondary caries, open margins, loss of retention, failure of endodontic treatment of the abutment and periodontal diseases. A total number of 249 failed fixed dental prostheses were evaluated. Of which 180 (39.7%) were single crowns, 159 (35.0%) were retainers and 117 (25.8%) were pontics in 69 fixed partial denture. The most common reason for replacement of fixed restorations was periodontal diseases affecting 92.8% of all types' restorations, followed by defective margin in 90.4% of examined restoration, poor aesthetic in 88% of restorations, while periapical involvement was found in 85.5% of fixed dental prosthesis. The survival rates of fixed prostheses were not predictable, and no association was found between number of years in service and the number of restorations. The most common reasons for replacing single unit fixed dental prostheses are periodontal diseases and periapical involvement, while defective margins and poor aesthetic mainly associated with multi-unit fixed dental prostheses. Key words: Failure, Fixed dental prosthesis, Survival, Replacement.

    The term "lean production," also known as "Lean," describes a process of operations management pioneered at the Toyota Motor Company that contributed significantly to the success of the company. Although developed by Toyota, the Lean process has been implemented at many other organizations, including those in health care, and should be considered by dental schools in evaluating their clinical operations. Lean combines engineering principles with operations management and improvement tools to optimize business and operating processes. One of the core concepts is relentless elimination of waste (non-value-added components of a process). Another key concept is utilization of individuals closest to the actual work to analyze and improve the process. When the medical center of the University of Kentucky adopted the Lean process for improving clinical operations, members of the College of Dentistry trained in the process applied the techniques to improve inefficient operations at the Walk-In Dental Clinic. The purpose of this project was to reduce patients' average in-the-door-to-out-the-door time from over four hours to three hours within 90 days. Achievement of this goal was realized by streamlining patient flow and strategically relocating key phases of the process. This initiative resulted in patient benefits such as shortening average in-the-door-to-out-the-door time by over an hour, improving satisfaction by 21%, and reducing negative comments by 24%, as well as providing opportunity to implement the electronic health record, improving teamwork, and enhancing educational experiences for students. These benefits were achieved while maintaining high-quality patient care with zero adverse outcomes during and two years following the process improvement project.

    To assess California dental hygiene educators' perceptions of an application of the American Dental Hygienists' Association's (ADHA) advanced dental hygiene practitioner model (ADHP) in medical settings where the advanced dental hygiene practitioner collaborates in medical settings with other health professionals to meet clients' oral health needs. In 2014, 30 directors of California dental hygiene programs were contacted to participate in and distribute an online survey to their faculty. In order to capture non-respondents, 2 follow-up e-mails were sent. Descriptive analysis and cross-tabulations were analyzed using the online survey software program, Qualtrics™. The educator response rate was 18% (70/387). Nearly 90% of respondents supported the proposed application of the ADHA ADHP model and believed it would increase access to care and reduce oral health disparities. They also agreed with most of the proposed services, target populations and workplace settings. Slightly over half believed a master's degree was the appropriate educational level needed. Among California dental hygiene educators responding to this survey, there was strong support for the proposed application of the ADHA model in medical settings. More research is needed among a larger sample of dental hygiene educators and clinicians, as well as among other health professionals such as physicians, nurses and dentists.

    The purpose of this project is to assess how information technology (IT) is being implemented and managed in U.S. dental schools. Recent advances in IT have restructured many of the administrative, curricular, and clinical functions in dental schools. Purchasing hardware and software and hiring personnel to maintain IT present significant financial and administrative commitments for these schools. A nine-question survey was sent to all U.S. dental schools via email with a follow-up postal mailing. Forty-six surveys were returned (83.6 percent response rate). The analysis indicates that dental schools are managing IT in vastly different ways. For example, 71 percent of the schools report a centralized structure, and 61 percent have a line item in the budget to manage IT. On average there are 4.4 full-time equivalents hired to manage IT, with the majority of these people being trained in IT (eight schools reported dually trained IT/dental personnel). The majority of schools report using software to manage their admissions process (70 percent), curriculum analysis (72 percent), and delivery of curriculum content (72 percent), as well as to manage their student clinics (91 percent, business aspect; 87 percent, patients; 65 percent, grading on clinic floor; 76 percent, managing clinical evaluations) and faculty practices (85 percent, business aspect; 65 percent, patients). The use of multimedia (50 percent) and simulation (52 percent) in the preclinical area is mixed. The purchase of laptops (24 percent) and PCs (11 percent) is required in almost a third of all schools participating in this survey. Dental schools in the United States are managing IT in a variety of different ways, using various internally and commercially available tools. The cost to institutions can be large and is usually handled in centralized structures in the school with fixed budgets. The results of this survey can be used to assist schools in the planning and implementation of IT at their

    The aim of this study was to document cariology education across Canadian dental schools. Ten faculty members who supervise cariology education at each of the ten Canadian dental schools were invited to participate in the study in 2016. An adapted version of the European Organization for Caries Research-Association for Dental Education in Europe cariology curriculum group questionnaire was used. Representatives of all ten dental schools completed the questionnaire, for a 100% response rate. In four schools, cariology and restorative dentistry were taught by the same department. Five schools had didactic/laboratory courses focusing primarily on cariology as well as a specific written curriculum. Six schools provided cariology-related hands-on workshops/laboratories before students started working with patients. In teaching cariology, seven institutions included dental hard tissues defects. The following caries detection methods were addressed didactically in cariology education: visual (10/10 total schools), tactile (9/10), International Caries Detection and Assessment System criteria (6/10), caries activity assessment (9/10), radiographic (10/10), and other detection tools (8/10). Seven schools charted activity of carious lesions in clinic. Only one school used the concept of caries risk assessment regularly in clinic. Clinical cariology teaching was carried out mostly by private dentists hired as clinical instructors (7/10) and faculty members involved in didactic cariology education (9/10). Calibration of faculty members for caries detection criteria was reported by only one school. The main concern reported by all institutions was the difficulty of implementing didactic instruction on cariology into clinical training. This study found that contemporary cariology concepts are in the process of being implemented in didactic education across Canadian dental schools, but all schools lacked appropriate integration of cariology education into clinical training.

    With dentistry rapidly evolving as new technologies are developed, this study aimed to identify the penetration of emerging dental technologies into the curricula of U.S. dental schools and to explore whether certain school characteristics affected adoption of these technologies. A 19-question survey was sent to the academic deans of all 62 U.S. dental schools. In addition to questions about characteristics of the school, the survey asked respondents to indicate where in their curricula the technology was incorporated: preclinical didactic, preclinical laboratory, clinical didactic, and/or clinical patient experience. Of 62 eligible schools, 33 useable responses were received, for a 52% response rate. The results showed that the greatest overall penetration of dental technologies was in preclinical didactic courses and the lowest was in the preclinical laboratory. Specific technologies implemented in the largest percentage of responding schools were digital radiography and rotary endodontics. The technologies with the lowest penetration were CAD/CAM denture fabrication and hard tissue lasers. These results suggest that the incorporation of technology into dental schools is following that of private practice as the most widely adopted technologies were those with the greatest acceptance and use in private practice. Among the respondents, factors such as class size and age of the school had greater impact on incorporation of technology than funding source and geographic location.

    Geriatric dentistry and its instruction are critical in a rapidly aging population. Japan is the world’s fastest-aging society, and thus geriatric dentistry education in Japan can serve as a global model for other countries that will soon encounter the issues that Japan has already confronted. This study aimed to evaluate geriatric dental education with respect to the overall dental education system, undergraduate geriatric dentistry curricula, mandatory internships, and graduate geriatric education of a selected dental school in Japan. Bibliographic data and local information were collected. Descriptive and statistical analyses (Fisher and Chi-square test) were conducted. Japanese dental schools teach geriatric dentistry in 10 geriatric dentistry departments as well as in prosthodontic departments. There was no significant differences found between the number of public and private dental schools with geriatric dentistry departments (p = 0.615). At Showa University School of Dentistry, there are more didactic hours than practical training hours; however, there is no significant didactic/practical hour distribution difference between the overall dental curriculum and fourth-year dental students’ geriatric dental education curriculum (p=0.077). Graduate geriatric education is unique because it is a four-year Ph.D. course of study; there is neither a Master’s degree program nor a certificate program in Geriatric Dentistry. Overall, both undergraduate and graduate geriatric dentistry curricula are multidisciplinary. This study contributes to a better understanding of geriatric dental education in Japan; the implications of this study include developing a clinical/didactic curriculum, designing new national/international dental public health policies, and calibrating the competency of dentists in geriatric dentistry.

    This article applies two well-known management and leadership models-Theory X and Theory Y, and Situational Leadership-to dental education. Theory X and Theory Y explain how assumptions may shape the behaviors of dental educators and lead to the development of "cop" and "coach" teaching styles. The Situational Leadership Model helps the educator to identify the teaching behaviors that are appropriate in a given situation to assist students as they move from beginner to advanced status. Together, these models provide a conceptual reference to assist in the understanding of the behaviors of both students and faculty and remind us to apply discretion in the education of our students. The implications of these models for assessing and enhancing the educational environment in dental school are discussed.

    Admissions committees in dental schools are charged with the responsibility of selecting candidates who will succeed in school and become successful members of the profession. Identifying students who will have academic difficulty is challenging. The aim of this study was to determine the predictive value of pre-admission variables for the first-year performance of six classes at one U.S. dental school. The authors hypothesized that the variables undergraduate grade point average (GPA), undergraduate science GPA (biology, chemistry, and physics), and Dental Admission Test (DAT) scores would predict the level of performance achieved in the first year of dental school, measured by year-end GPA. Data were collected in 2015 from school records for all 297 students in the six cohorts who completed the first year (Classes of 2007 through 2013). In the results, statistically significant correlations existed between all pre-admission variables and first-year GPA, but the associations were only weak to moderate. Lower performing students at the end of the first year (lowest 10% of GPA) had, on average, lower pre-admission variables than the other students, but the differences were small (≤10.8% in all categories). When all the pre-admission variables were considered together in a multiple regression analysis, a significant association was found between pre-admission variables and first-year GPA, but the association was weak (adjusted R 2 =0.238). This weak association suggests that these students' first-year dental school GPAs were mostly determined by factors other than the pre-admission variables studied and has resulted in the school's placing greater emphasis on other factors for admission decisions.

    The issues of cheating and plagiarism in educational settings have received a large amount of attention in recent years. The purpose of this study was to assess the degree to which academic integrity issues currently exist in the dental schools throughout the United States and Canada. An online survey was developed to gather data pertaining to this topic from two key groups in dental education: faculty and students. Responses were obtained from 1,153 students and 423 faculty members. The results of the survey clearly reveal that cheating is a significant problem in dental schools and that significant differences exist between students' and faculty members' perceptions of academic integrity. The challenge for dental schools is to identify effective strategies to prevent cheating opportunities and to implement and enforce effective means of dealing with specific examples of cheating.

    The shape memory alloys are quite fascinating materials characterized by a shape memory effect and super elasticity which ordinary metals do not have. This unique behaviour was first found in a Au-47.5 at % Cd alloy in 1951, and was published in 1963 by the discovery of Ti-Ni alloy. Shape memory alloys now being practically used as new functional alloys for various dental and medical applications.

    Conclusion: The microhardness of the bracket-like blocks made by our new material is superior to the commercially available brackets, even after thermocycling. Our results indicate that the evaluated liquid crystalline epoxy nanocomposite materials are of an appropriate quality for application in dental core and post systems and in various restorations. By applying technology to refine manufacturing processes, these new materials could also be used to fabricate esthetic brackets for orthodontic treatment.

    Prior research has suggested that dental students experience high rates of stress, anxiety, and mood concerns, which have been linked to poor academic performance, health concerns, and substance abuse. The aim of this study was to evaluate the impact of an embedded counseling office at the University of Iowa College of Dentistry & Dental Clinics in its first three academic semesters. Data were gathered from students attending appointments, and two inventories were used to monitor students' counseling progress and gather psychological outcomes data: the Counseling Center Assessment of Psychological Symptoms-34 (CCAPS-34) and the Outcome Rating Scale (ORS). In the three semesters, 55 students attended 251 counseling appointments, with an average of 4.5 appointments per student. Their presenting psychological concerns included academic concerns, time management, test anxiety, study skills, low self-esteem, self-care, interpersonal conflicts, anxiety, depression, stress management, sexual concerns, substance abuse, eating/body image concerns, work-life balance, and financial issues. The CCAPS-34 data showed that, at initial clinical assessment, students experienced moderate levels of depression, generalized anxiety, social anxiety, academic distress, and overall psychological distress; 45 (82%) showed clinically significant symptoms on at least one CCAPS-34 subscale. The ORS data further showed that the students entered counseling experiencing high levels of psychological distress. A positive relationship was found between number of counseling appointments and increased overall functioning. These results suggest that an embedded counseling office can help dental schools meet the needs of their students.

    To evaluate the prevalence and aetiology of dental erosion in Greek minority school children living in Istanbul (Turkey). The present study was initiated in four Greek minority elementary schools in Istanbul where a total of 83 children (46 girls, 37 boys) between ages 7-14 years old were examined. Children were categorised into 7-11 and 12-14 ages groups. Data were obtained by clinical examination, questionnaire and standard data records. All tooth surfaces were examined, dental erosion was recorded per tooth and classified according to the index of Lussi et al. [1996] In the 7-11 yrs old group, 47.4% (n:18) of the children exhibited dental erosion while in 12-14 yrs old group, 52.6% (n:20) of the children exhibited dental erosion. There were no statitistical differences between age, gender groups and findings of dental erosion (p>0.05). However prevalence of dental erosion in 12-14 yrs old was twice that of the 7-11 years old children. In general, an unusual drinking pattern of slow swallowing of beverages significantly affected the prevalence of dental erosion (p=0.03). Multiple regression analysis revealed no relationship between dental erosion and related erosive sources such as medical conditions, brushing habits, swimming, and the consumption of acidic fruit juices and beverages (p>0.05). However it should be noted that the sample size in the current study was small.

The cross-sectional retrospective study comprises professors, students and technical-administration personnel who worked in the laboratory from 2001 to 2008 (n = 566. An electronic questionnaire, prepared by software developed for this purpose, was sent to subjects between May and August 2008 for data collection. Ninety-one (34.2% out of 266 participants reported some type of exposure to BM. There was no difference between the occurrence of accidents according to the subjects’ category (p = 0.496 and sex (p = 0.261. Most of the subjects reported cutaneous exposure (76.9% comprising saliva (68.1% and blood (48.3%. The fingers were the body members most affected. Accidents occurred mostly during clinical (34.1% and surgical (30.8% procedures. Although the use of protection equipments was high (82.9%, only 26.4% of subjects reported the accident and only 28.6% sought immediate help. Most of the injured subjects failed to report the accidents and did not comply with the guidelines. Others trivialized basic behavior such as the interruption of the procedure to seek medical assistance.

    The light intensity of a light-curing unit is a crucial factor that affects the clinical longevity of resin composites. This study aimed to investigate the efficiency of light-curing units in use at a local governmental dental school for curing conventional and bulk-fill resin materials. A total of 166 light-curing units at three locations were examined, and the brand, type, clinic location, diameter of curing tip, tip cleanliness (using a visual score), and the output (in mW/cm 2 using a digital radiometer) were recorded. Only 23.5% of the units examined had clean tips, with the graduate student clinical area containing the highest percentage of clean tips. Further, tips with poor cleanliness score values were associated with significantly lower output intensities. A small percentage (9.4%) of units was capable of producing intensities higher than 1,200 mW/cm 2 and lower than 600 mW/cm 2 (7.6%). The majority of the low intensity units were located in the undergraduate student area, which also contained the highest number of units with intensities between 900 and 1,200 mW/cm 2 . The output of all the units in service was satisfactory for curing conventional resin composites, and most units were capable of curing bulk-fill resin materials.

    2017-08-01

    The purpose of this study was to examine data published over the past two decades to identify trends in the basic sciences curriculum in dental education, provide an analysis of those trends, and compare them with trends in the basic sciences curriculum in medical education. Data published from the American Dental Association (ADA) Surveys of Dental Education, American Dental Education Association (ADEA) Surveys of Dental School Seniors, and two additional surveys were examined. In large part, survey data collected focused on the structure, content, and instructional strategies used in dental education: what was taught and how. Great variability was noted in the total clock hours of instruction and the clock hours of basic sciences instruction reported by dental schools. Moreover, the participation of medical schools in the basic sciences education of dental students appears to have decreased dramatically over the past decade. Although modest progress has been made in implementing some of the curriculum changes recommended in the 1995 Institute of Medicine report such as integrated basic and clinical sciences curricula, adoption of active learning methods, and closer engagement with medical and other health professions education programs, educational effectiveness studies needed to generate data to support evidence-based approaches to curriculum reform are lacking. Overall, trends in the basic sciences curriculum in medical education were similar to those for dental education. Potential drivers of curriculum change were identified, as was recent work in other fields that should encourage reconsideration of dentistry's approach to basic sciences education. This article was written as part of the project "Advancing Dental Education in the 21st Century."

    Full Text Available Objectives: Evaluate the way the topics for the study of pain mechanisms in general, and Orofacial Pain (OFP and temporomandibular disorders (TMDs more specifically, are addressed in undergraduate courses curricula, and also to verify the existence of specialist OFP/TMD teachers in Brazilian dental schools. Methods: Between July 2010 and January 2011, course Coordinators/Directors of all dental schools duly registered at the Ministry of Education were invited to answer a questionnaire on topics related to OFP/TMD teaching in their institutions. Results: Fifty-three dental schools representatives answered the questionnaire. The study of pain mechanisms was found to cover an average of less than 10% of the courses' total time. Pharmacology, Endodontics and Physiology were identified as the departments usually responsible for addressing pain mechanisms in dental courses. Psychosocial aspects were found to occupy a very small proportion in the syllabi, while most of the content referred to biological or somatic aspects. OFP/TMD is addressed by a specific department in only 28.4% of the participating dental schools, while in most cases (46.3%, OFP/TMD is under the responsibility of the Prosthodontics department. Only 38.5% of respondents indicated that they had a specialist OFP/TMD teacher in their Schools. Conclusion: Among the Brazilian dental schools participating in the study, the teaching of OFP/TMD was found to be insufficient, segmented or with an extremely restricted focus. This initial assessment indicates that Curricular Guidelines for the study of OFP/TMD at undergraduate dental schools should be developed and implemented to facilitate their appropriate inclusion into the curricula and in specific pedagogical projects.

    Full Text Available Abstract Background Follow-up studies of former students are an efficient way to organize the entire process of professional training and curriculum evaluation. The aim of this study was to identify professional profile subgroups based on job-related variables in a sample of former students of a Brazilian public dental school. Methods A web-based password-protected questionnaire was sent to 633 registered dentists who graduated from the Federal University of Goias between 1988 and 2007. Job-related information was retrieved from 14 closed questions, on subjects such as gender, occupational routine, training, profits, income status, and self-perception of professional career, generating an automatic database for analysis. The two-step cluster method was used for dividing dentists into groups on the basis of minimal within-group and maximal between-group variation, using job-related variables to represent attributes upon which the clustering was based. Results There were 322 respondents (50.9%, predominantly female (64.9% and the mean age was 34 years (SD = 6.0. The automatic selection of an optimal number of clusters included 289 cases (89.8% in 3 natural clusters. Clusters 1, 2 and 3 included 52.2%, 30.8% and 17.0% of the sample respectively. Interpretation of within-group rank of variable importance for cluster segmentation resulted in the following characterization of clusters: Cluster 1 - specialist dentists with higher profits and positive views of the profession; Cluster 2 - general dental practitioners in small cities; Cluster 3 - underpaid and less motivated dentists with negative views of the profession. Male dentists were predominant in cluster 1 and females in cluster 3. One-way Anova showed that age and time since graduation were significantly lower in Cluster 2 (P Conclusions Cluster analysis was a valuable method for identifying natural grouping with relatively homogeneous cases, providing potentially meaningful information for

    The paper presents the assessment of tooth decay prevalence in clinically homogenous groups of children receiving long-term preventive program (PP) in school dental facilities. Five-years PP were introduced in clinical practice in 2 Moscow schools. Preventive treatment was performed by dental hygienist. The results show that systematic preventive treatment in school dental offices starting from elementary school allows reducing dental caries incidence 46-53% and stabilize the incidence of caries complications. It should be mentioned though that analysis of individualized outcomes proves heterogeneity of study results despite of equal conditions of PP. Potentially significant hence is early diagnostics and treatment of initial caries forms as demineralization foci, especially in children with intensive tooth decay. Optimization of pediatric dentist and dental hygienist activity in school dental facilities is the main factor of caries prevention efficiency.

    Laminate veneers are a conservative treatment of unaesthetic anterior teeth. The continued development of dental ceramics offers clinicians many options for creating highly aesthetic and functional porcelain veneers. This evolution of materials, ceramics, and adhesive systems permits improvement of the aesthetic of the smile and the self-esteem of the patient. Clinicians should understand the latest ceramic materials in order to be able to recommend them and their applications and techniques, and to ensure the success of the clinical case. The current literature was reviewed to search for the most important parameters determining the long-term success, correct application, and clinical limitations of porcelain veneers.

    Obesity and dental caries are increasing epidemics, especially among children and adolescents. This epidemiological observational cross-sectional study was conducted to assess the possible association between body mass index (BMI) and dental caries among 111,792 school children and adolescents in Jiangsu Province. We found that 13.14% participants of the study sample were overweight, and 7.37% were obese. The prevalence of dental caries was 12.95% in overweight and 7.89% in obese students. There were significant differences in caries prevalence by sex, region, age group, and BMI. Overweight and obesity statuses were associated with dental caries among the study population. BMI and dental caries present a continuous health problem. Thus, we recommend that oral health promotion be used for caries prevention and control.

    The ICRP, in its publication 73 entitled Radiological Protection and Safety in Medicine states (paragraph 128) that one important need is to provide adequate resources for the education and training in radiological protection for future professional and technical staff in medical practice. The training programme should include initial training for all incoming staff and regular updating retraining. The European Directive 97/743/EURATOM on Medical Exposure (MED) lays down requirements for education and training. The document RP 116 published by the European commission give guidelines on Education and Training in Radiation Protection and in its paragraph 51 establish that Members States shall encourage the introduction of a course on radiation protection in the basic curriculum of medical and dental schools according to the EC Medical Exposure Directive (MED). In the Spanish legislation RD 815/2001 referred to the medical exposures, it is encourage the need for the introduction of Radiological Protection courses in Medicine and Dental schools with the objective of patient protection. In this study it has been analysed the actual situation of the education and training in Radiation Protection in Dental Schools in Spain. In addition it is described the experience of the University of Sevilla. The results of the study shows that only 4 from 9 dental schools have disciplines of Radiation Protection in its curriculum. In one of them the course is mandatory and has a content of 2 credits (20 hours). In the rest of dental schools the discipline has an optional character with an average of 4 credits. The discipline of Radiation Protection of the curriculum of Dental School at Sevilla university has 4 credits and it is configured as a course with the necessary requirements from the Spanish Nuclear Safety Council to obtain the Radiological Accreditation of Responsible of Dental Radiodiagnostic Installations. This diploma is given once the students have finished the Bachelor

    OBJECTIVES. To investigate the level of knowledge about emergency management of dental trauma among Hong Kong primary and secondary school teachers. DESIGN. Questionnaire survey. SETTING. A teachers' union that unites 90% of teachers in Hong Kong. PARTICIPANTS. Randomly selected primary and secondary school teachers. RESULTS. Only 32.8% of respondents correctly stated that a person sustaining dental trauma should go to dentists directly. In all, 73.1% of teachers correctly stated that a dental trauma patient should go for treatment immediately. Only 32.5% knew that a fractured tooth should be put in liquid. Even fewer (23.2%) realised that the displaced tooth should be repositioned back to the original position. Relatively more respondents (74.7%) understood that an avulsed baby tooth should not be put back. Disappointingly, only 16.3% of teachers knew that an avulsed permanent tooth should be replanted. Furthermore, only 29.6% of teachers thought that they were able to distinguish between deciduous teeth and permanent teeth, whilst 20.4% correctly identified at least one of the appropriate mediums: milk, physiological saline or saliva, for storing an avulsed tooth. Teachers who previously received first-aid training with dental content or acquired dental injury information from other sources, scored significantly higher than teachers without such training or acquired information. CONCLUSION. The knowledge on emergency management of dental trauma among primary and secondary school teachers in Hong Kong is insufficient, particularly on the handling of permanent tooth avulsion and the appropriate storage medium for avulsed teeth. Receipt of first-aid training with dental contents and acquisition of dental injury information from other sources were positively correlated with knowledge in managing dental trauma.

    The aim of this pilot study was to assess adult patients' ability to read and understand two communication tools at the University of California, Los Angeles, School of Dentistry: the dental school clinic website and a patient education brochure pertaining to sedation in children that was written by dental school personnel. A convenience sample of 100 adults seeking treatment at the school's general dental clinic during 2012-13 completed a health literacy screening instrument. They were then asked to read clinic educational and informational materials and complete a survey. Analyses were conducted to determine the association between the subjects' oral health literacy and sociodemographics and their ability to locate and interpret information in written oral health information materials. SMOG and Flesch-Kincade formulas were used to assess the readability level of the electronic and written communication tools. The results demonstrated an association between these adults' oral health literacy and their dental knowledge and ability to navigate health information website resources and understand health education materials. Health literacy was not associated with age or gender, but was associated with education and race/ethnicity. The SMOG Readability Index determined that the website and the sedation form were written at a ninth grade reading level. These results suggest that dental schools and other health care organizations should incorporate a health-literate approach for their digital and written materials to enhance patients' ability to navigate and understand health information, regardless of their health literacy.

    The aim of this study was to determine the number and size of postdoctoral teaching programs in geriatric dentistry in U.S. dental schools and other health professions educational institutions and those programs with Health Resources and Services Administration (HRSA) funding. In 2015, all 67 U.S. dental schools were contacted via email with a questionnaire to ask if they had a postdoctoral program in geriatric dentistry; if they did, they were asked to report the length and size of the program. Directors of all 16 HRSA-funded geriatric fellowships were also invited to participate in the survey. Fifty-six of the 67 (83.6%) dental schools and 15 of the 16 (93.8%) HRSA-funded programs completed the questionnaire. Postdoctoral geriatric dentistry programs were reported in 12 dental schools and six medical institutions, although only six programs were currently accepting fellows. The length of the programs was 12-36 months. The maximum number of residents in any program was ten. The oldest program was in Minnesota; it began in 1981. The newest program was beginning in 2017 at Boston University as a revised version of its previous HRSA-funded program. The loss of HRSA funding has had a major negative impact on the number of training programs. Future research is needed to determine how the loss of HRSA-funded programs has affected the availability of educators in geriatric dentistry for dental schools and the services provided to the geriatric community.

    The objectives of this study were to evaluate the number and range of clinical procedures completed by undergraduate dental students in pediatric dentistry in Cork University Dental School and Hospital, Ireland, and to compare the number of procedures undertaken with the subsequent examination scores. The work comprised a retrospective audit of clinical logbooks for all of the undergraduate dental students in one cohort through their fourth and fifth clinical years between 2004 and 2006. Thirty-four quantitative logbooks were audited. Students had seen a total of 1,031 patients, and each student had completed a full course of dental treatment for an average of twenty-two children. Students completed means of 30.2 restorative procedures for children, fourteen in deciduous dentition (range six to twenty-eight), and seventeen in permanent dentition (range seven to twenty-eight). Continuity of education and care (measured through children having their treatment fully completed by the same student) was 72 percent. A moderate positive correlation between levels of clinical experience and exam score was identified. All students gained experience in management of child patients with students providing care for an average of thirty children and a minimum of nineteen.

    Health care studies are usually considered to be complex, demanding and time consuming. The right motivation toward choosing a career in the health field is of utmost importance for the successful completion of studies. The aim of this study was to gain insight into the factors motivating students at the School of Dental Medicine University of Zagreb, Croatia and, also, to examine their career perceptions. Based on specific questions from available literature, a questionnaire was designed and a total of 270 questionnaires were distributed to the first year students during 2013, 2014 and 2015. A total of 206 students responded, for a response rate of 76.3%. 26.9% of students enrolled in dental studies because it was their first career choice; 16.4% of them believed that it is easy to find a regular job in dentistry. 9.9% of students thought that salaries are high in the field of dental medicine. 45.4% of the first year students were interested in a career in private practice after graduation. These results provide interesting clues to motivation and give additional insights into the expectations of students regarding their studies and profession. The obtained data can be used for the further improvements in the quality of dental study curricula and teaching process.

    Community-based dental education (CBDE) enhances students' clinical expertise, improves their cultural competence, increases access to care, and fosters community engagement. As emphasis on CBDE has increased over the last decades, the aim of this survey study was to determine how CBDE is currently being implemented in U.S. dental schools. The study used a 20-item, author-designed survey emailed in April to August 2015 to 60 of the 65 U.S. dental schools, excluding those that had been recently established. Of the 60 schools, representatives of 33 responded, resulting in a 55% response rate: 70% public and 30% private. These respondents reported that the extramural sites being used the most were community clinics (90.9%), Federally Qualified Health Clinics (66.7%), public health clinics (54.5%), and Indian Health Service clinics (42.4%). The majority of responding schools (63.6%) had ten or more sites available for rotations, and the rotation lengths were 1-2 weeks (29%), 2-4 weeks (25%), 4-6 weeks (29%), 6-8 weeks (3.2%), and 8-10 weeks (12.9%). Most of the respondents (78.8%) reported that their students were unable to be assessed for clinical competencies at external clinical sites, but roughly half allowed students to receive clinical credit. After students completed their rotations, the majority of the respondents (81.8%) reported that students were required to produce a reflection, and 87.9% reported that students completed a post-rotation survey. Considering the benefits of CBDE for students' education and for improving access to oral health care, it is encouraging that over 45% of the responding schools required their students to spend four weeks or longer on external rotations.

    The physical understanding of the optical properties of dental biomaterials is mandatory for their final success in restorative applications.Light propagation in biological media is characterized by the absorption coefficient, the scattering coefficient, the scattering phase function,the refractive index, and the surface conditions (roughness). We have employed the inverse adding-doubling (IAD) method to combine transmittance and reflectance measurements performed using an integrating-sphere setup with the results of the previous scattering-anisotropygoniometric measurements. This has led to the determination of the absorption and the scattering coefficients. The aim was to optically characterize two different dental-resin composites (nanocomposite and hybrid) and one type of zirconia ceramic, and comparatively study them. The experimental procedure was conducted under repeatability conditions of measurement in order to determine the uncertainty associated to the optical properties of the biomaterials. Spectral variations of the refraction index and the scattering anisotropy factor were also considered. The whole experimental procedure fulfilled all the necessary requirements to provide optical-property values with lower associated uncertainties. The effective transport coefficient presented a similar spectral behavior for the two composites but completely different for the zirconia ceramic. The results demonstrated that the scattering anisotropy exerted a clearly distinct impact on the optical properties of the zirconia ceramic compared with those of the dental-resin composites.

    Oral piercing can lead to complications and dentists are in a unique position to detect such complications. The purpose of this study was: (i) to assess the immediate and the long-term effects, on dental students, of a training programme about oral piercing knowledge; and (ii) to assess the immediate effect, on adolescents, of a single educational intervention session about oral piercing. A training programme for dental students (n = 66) was carried out in three phases. The last phase consisted of preparing and giving talks about oral piercing at schools, which was delivered by a random selection of dental students involved in the training programme. Dental students answered a questionnaire about oral piercing knowledge, before, immediately after (only the dental students included in the last phase) and 12 months after the training programme. Adolescents (n = 347) answered a survey about oral piercing knowledge before and after the talks. There were statistically significant differences in all comparison groups, except for the results in the 'before intervention' and in the '12 months after intervention' groups among dental students who had not prepared and given the talks to adolescents. Knowledge about oral piercing significantly improved among adolescents when comparing results before (mean questionnaire score = 3.0) and after (mean questionnaire score = 6.2) the talks. Oral piercing educational intervention had a favourable impact on adolescents and dental students, particularly among those who were more involved in the learning process. © 2017 FDI World Dental Federation.

    Transcription or recording of lectures has been in use for many years, and with the availability of high-fidelity recording, the practice is now ubiquitous in higher education. Since technology has permeated education and today's tech-savvy students have expectations for on-demand learning, dental schools are motivated to record lectures, albeit with positive and negative implications. This Point/Counterpoint article addresses the question of whether lecture recording should be mandatory in U.S. dental schools. Viewpoint 1 supports the statement that lecture recording should be mandatory. Proponents of this viewpoint argue that the benefits-notably, student satisfaction and potential for improvement in student performance-outweigh concerns. Viewpoint 2 takes the opposite position, arguing that lecture recording decreases students' classroom attendance and adversely affects the morale of educators. Additional arguments against mandatory lecture recordings involve the expense of incorporating technology that requires ongoing support.

    To investigate dental erosion among 12-14 year old Sudanese school children and evaluate the associated risk factors. Cross sectional survey in secondary schools in Khartoum city, Sudan. A sample of 157 school children was obtained from both private and public schools. Erosion on the labial and palatal surfaces of maxillary incisors was measured by criterion based on the Smith and Knight Tooth Wear Index. Dietary intake and other related factors were assessed using a questionnaire. The overall erosion prevalence in this group was 66.9%, of which 45.2% was mild and 21.7% was moderate erosion. A strong association was found between erosion and private schooling (higher socioeconomic groups), carbonated drinks, herbal hibiscus drink and traditional acidic food consumption. There was a high prevalence of dental erosion among Sudanese school children which was mild to moderate in severity and was strongly associated with acidic dietary intake

    In the last 30 years, Chile has undergone noteworthy economic development and an exponential growth in the access of its population to higher education. The aim of this paper was to review the changes in academic, economic and workforce issues that occurred as a consequence of the growth in supply of undergraduate dental vacancies between 1997 and 2011. Data collected from the Consejo de Educación Superior - CES, Comisión Nacional de Acreditación - CNA, and Instituto Nacional de Estadísticas de Chile - INE included these variables: number of dental schools, school type (private or traditional, see explanation below), city where the school is located, entry vacancies, total student enrollment, admission scores, percentile rank of dentistry as a university career, tuition fees, accreditation status, and number of inhabitants. There was an exponential increase in dental schools in Chile (5 to 34) that occurred in association with the rise in tuition fees (US$ 3900 to US$ 9800), a deterioration in the academic level of dental students (650 to 550 points in admission scores) and a predicted 77.5% oversupply of dentists by 2025, according to WHO criteria. The exponential increase in dental schools in Chile brought about negative consequences, such as increasing career costs, deterioration in the academic level of dental students, and an oversupply of dentists, associated with lower incomes and possibly leading to unemployment. Additional research should be conducted to determine whether an increase in the number of dentists can improve the population's access to dental care and reduce the oral disease burden.

    Zirconia (ZrO 2 ) based dental ceramics have been considered to be advantageous materials with adequate mechanical properties for the manufacturing of medical devices. Due to its very high compression strength of 2000 MPa, ZrO 2 can resist differing mechanical environments. During the crack propagation on the application of stress on the surface of ZrO 2 , a crystalline modification diminishes the propagation of cracks. In addition, zirconia's biocompatibility has been studied in vivo, leading to the observation of no adverse response upon the insertion of ZrO 2 samples into the bone or muscle. In vitro experimentation has exhibited the absence of mutations and good viability of cells cultured on this material leading to the use of ZrO 2 in the manufacturing of hip head prostheses. The mechanical properties of zirconia fixed partial dentures (FPDs) have proven to be superior to other ceramic/composite restorations and hence leading to their significant applications in implant supported rehabilitations. Recent developments were focused on the synthesis of zirconia based dental materials. More recently, zirconia has been introduced in prosthetic dentistry for the fabrication of crowns and fixed partial dentures in combination with computer aided design/computer aided manufacturing (CAD/CAM) techniques. This systematic review covers the results of past as well as recent scientific studies on the properties of zirconia based ceramics such as their specific compositions, microstructures, mechanical strength, biocompatibility and other applications in dentistry.

    2017-08-01

    The aim of this study was to assess the current teaching of geriatric dentistry in U.S. dental schools and compare the findings to previous reports. Academic deans at all 67 U.S. dental schools were contacted in November 2015 via email, asking them to complete a questionnaire about the teaching of geriatric dentistry or gerodontology at their institution. Questionnaires were received from 56 of the 67 schools (84% response rate). The results showed that geriatric dentistry was taught in all responding schools; for 92.8% of the respondents, the instruction was compulsory. Among the responding schools, 62.5% were teaching it as an independent course, 25% as an organized series of lectures, and 8.9% as occasional lectures in parts of other courses. In addition, 57.1% had some form of compulsory clinical education in geriatric dentistry. Public schools, as opposed to private schools, were marginally associated with an increased interest in expanding geriatric dentistry teaching (p=0.078). No differences were found between any teaching variables and school location. This study found that the form of education in geriatric dentistry in U.S. dental schools differed in many ways, but the teaching of geriatric dentistry had increased among all respondents and had been increasing for over 30 years. Future research is needed to determine the impact of this teaching on services to the geriatric community.

    Immediate management of traumatized teeth is often critical to the prognosis of the teeth. Most of the traumatic dental injuries occur at home, followed by school. There is a high probability that first aid would be given by lay people such as parents, teachers, or coaches. Knowledge of those people regarding emergency management of dental trauma is crucial for better prognosis. To investigate: (i) the knowledge of elementary school teachers regarding traumatic dental injuries to permanent teeth and emergency treatment, (ii) their source of information, and (iii) the demand for more education in dental trauma. A three-part questionnaire comprised of questions regarding demographic data, attitude, and knowledge about dental injuries was distributed to teachers in 12 elementary schools in the Tel-Aviv area, Israel. The average knowledge score was 4.59 (in a scale of 0-10). Three individual predictors significantly improved the respondents' knowledge: being in the 35-49-year age group (P-value = 0.042), those who had children themselves (P-value = 0.002) and those who had previous experience with trauma (P-value = 0.049). There was no correlation between the demand for further education in dental trauma and knowledge score. The knowledge regarding management of traumatic dental injuries in a group of teachers in the Tel-Aviv area is inadequate. Educational programs as well as addition to the curriculum are necessary to improve their emergency management of traumatic dental injuries and provide better protection to the students. © 2011 John Wiley & Sons A/S.

    This study assesses the dental erosion status of 12-year-old Indonesian children and studies the determinants of dental erosion of these children. The survey was performed in 2016 with ethics approval. A multistage cluster proportional to size random sampling method was adopted to select 12-year-old children in 24 primary schools in Jakarta. The parents were asked to complete a self-administered questionnaire concerning their children’s diet and oral health habits. The children were examined by a single calibrated examiner. Detection of dental erosion followed basic erosive wear examination (BEWE) criteria. A total of 487 children participated in the survey. Most children (88%) had at least some signs of erosion (BEWE > 0), with dentin being involved in 50% of the cases (BEWE = 2). Dental erosion was significantly related to gender, the frequencies of citric tea consumption, parent’s dental knowledge, father’s education, and dental caries (OR = 3.148). The 12-year-old Indonesian school children who lived in Jakarta had signs of erosion, although severe erosion was not found. Screening programs should be provided to identify risk groups so early preventive measures can be taken.

    This study explored stress predictors and the role of instructional methods and institutional differences in perceived stress levels amongst students at two Asian dental schools. An anonymous questionnaire was distributed to undergraduate dental students at Tokyo Medical and Dental University (TMDU), Japan and the University of Medicine and Pharmacy (UMP), Hochiminh City, Vietnam in 2016. Data concerning the students' demographic information and grades, and responses to the Perceived Stress Scale (PSS) and Dental Environment Stress questionnaire (DES) were collected. The questionnaires were prepared in English and translated into Japanese and Vietnamese following a forward-backward translation process. Altogether 684 students answered the questionnaire with a response rate of 97% for TMDU and 89% for UMP. The mean DES score of UMP students was significantly higher than TMDU (P stress scores in several areas than UMP preclinical students. Having dentistry as their first choice of educational programme was a significant stress predictor for Japanese students whilst the clinical practicum was a significant stress predictor for Vietnamese students. Previous academic performance was not a significant stress predictor for students at either dental school. Dental students of an integrated, active-learning curriculum reported lower stress levels than students of a traditional, discipline-based curriculum. © 2018 John Wiley & Sons A/S.

    Regular dental attendance is significant in maintaining and improving children's oral health and well-being. This study aims to determine the factors that predict and influence dental visits in primary school children residing in the rural community of Lithgow, New South Wales (NSW), Australia. All six primary schools of Lithgow were approached to participate in a cross-sectional survey prior to implementing water fluoridation in 2014. Children aged 6-13 years (n = 667) were clinically examined for their oral health status and parents were requested to complete a questionnaire on fluoride history, diet, last dental visit, and socio-demographic characteristics. Multiple logistic regression analyses were employed to examine the independent predictors of a 6-monthly and a yearly dental visit. Overall, 53% of children visited a dentist within six months and 77% within twelve months. In multiple logistic regression analyses, age of the child and private health insurance coverage were significantly associated with both 6-monthly and twelve-month dental visits. In addition, each serve of chocolate consumption was significantly associated with a 27% higher odds (OR = 1.27, 95% CI: 1.05-1.54) of a 6-monthly dental visit. It is imperative that the socio-demographic and dietary factors that influence child oral health must be effectively addressed when developing the oral health promotion policies to ensure better oral health outcomes.

    Novel liquid crystalline epoxy nanocomposites, which exhibit reduced polymerization shrinkage and effectively bond to tooth structures, can be applied in esthetic dentistry, including core and post systems, direct and indirect restorations, and dental brackets. The purposes of this study were to investigate the properties of liquid crystalline epoxy nanocomposites including biocompatibility, microhardness, and frictional forces of bracket-like blocks with different filler contents for further clinical applications. In this study, we evaluated liquid crystalline epoxy nanocomposite materials that exhibited various filler contents, by assessing their cell activity performance using a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay and their microhardness with or without thermocycling. We also evaluated the frictional force between bracket-like duplicates and commercially available esthetic bracket systems using Instron 5566. The liquid crystalline epoxy nanocomposite materials showed good biocompatibility. The materials having high filler content demonstrated greater microhardness compared with commercially available bracket materials, before and after the thermocycling treatment. Thus, manufacturing processes are important to reduce frictional force experienced by orthodontic brackets. The microhardness of the bracket-like blocks made by our new material is superior to the commercially available brackets, even after thermocycling. Our results indicate that the evaluated liquid crystalline epoxy nanocomposite materials are of an appropriate quality for application in dental core and post systems and in various restorations. By applying technology to refine manufacturing processes, these new materials could also be used to fabricate esthetic brackets for orthodontic treatment. Copyright © 2014.

    To determine the prevalence of dental caries among disabled individuals attending special schools in Vhembe districts. A cross-sectional descriptive study was conducted from January to June 2012 among disabled individuals receiving special care in four specialised schools of Vhembe District. The research protocol had been approved by the Ethics Committee of the University of Limpopo, Polokwane Campus. Informed consent was obtained from the parents of the participants and from the respective school principals. Oral health examinations took place at the school under natural light, with participants seated on an ordinary chair/wheelchair. Dental caries examinations were carried out, using a mirror and wooden spatula in accordance with World Health Organisation (WHO) criteria and methods. Decayed, missing and filled primary and permanent teeth (dmft, DMFT) were recorded. All disabled individuals who were available during a screening period, were included. Those who were not available, as well as those whose health conditions could be compromised by dental examinations, were excluded. The number of decayed teeth ranged from 0-7 in children below 6 years, 0-12 in children below 11 years; and 0-17 among young adults. The mean decay scores and the numbers of missing teeth increased with age. Only 3 (0.04%) individuals had dental fillings. The mean dmft score of children under 6 years was 5.51 (+/- 2.1), ranging from zero to 8. The mean DMFT's of the 11-18 and 19 years and older groups were 7.38 (+/- 3.22) and 10.24 (+/- 2.97) respectively. Disabled individuals exhibited higher caries prevalence and unmet dental needs than the same age general population in Limpopo. Preventive measures and dental treatment should be considered urgent requirements at special needs schools in the Vhembe District.

    This study was aimed to compare skin entrance dose of digital radiography with that of film radiography and to show the dose reduction achievement with digital systems at 11 dental schools in Korea. Forty six intraoral radiographic systems in 11 dental schools were included in this study. Digital sensors were used in 33 systems and film was used in 13 systems. Researchers and the volunteer visited 11 dental schools in Korea. Researchers asked the radiologic technician at each school to set the exposure parameters and aiming the x-ray tube for the peri apical view of the mandibular molar of the volunteer. The skin entrance doses were measured at the same exposure parameters and distance by the technician for each system with a dosimeter (Multi-O-Meter; Unifors instruments, Billdal, Sweden). The median dose was 491.2 {mu}Gy for digital radiography and 1,205.0 {mu}Gy for film radiography. The skin entrance dose in digital radiography was significantly lower than that of film radiography (p<0.05). Fifty-nine percent skin entrance dose reduction with digital peri apical radiography was achieved over the film radiography in Korean dental schools.

    Over the past 20 years the incorporation of implant dentistry into academia has been documented in some detail for North American dental schools but has not been pursued on an international level. In June of 1993, we surveyed 51 dental schools outside of the United States affiliated with the University of Pennsylvania School of Dental Medicine's Office of International Relations concerning their teaching involvement with implant dentistry. Results from the 44 (86 percent) responding schools suggest that implant dentistry is being incorporated into predoctoral curriculums. Industrialized countries were more inclined to provide implant education. Insufficient time and the thought that the predoctoral level was not the place for implant dentistry were cited as some of the reasons for not incorporating implant dentistry into the curriculum. Oral surgery, prosthodontics, and periodontics departments developed and administered the implant curriculum. Formats varied among schools with respect to allotted time, curricular placement, laboratory experience, and clinical participation. Didactic material most frequently presented included a historical overview, diagnosis and treatment planning, classification of dental implants, and surgical and prosthetic concepts. Clinical involvement varied from actual implant placement to observation of prosthodontic procedures. Results were categorized based on the TOEFL (Test of English as a Foreign Language) classification of countries in six regions.

    To assess, by means of self-administered structured questionnaire, the level of knowledge of primary schools teachers in Ajman with regards to the immediate emergency management of dental trauma. The questionnaire was sent to teachers in randomly selected primary schools in Ajman. A total of 161 teachers responded (response rate 84.4%). The questionnaire surveyed teachers' background, knowledge and management of tooth fracture, avulsion, and also investigated teachers' attitudes and self-assessed knowledge. Ninety-one percent of the teachers were females, 51.6% in their thirties and 61.5% had university qualification. Fifty teachers had received formal first aid training, and only thirteen of them recalled that they had received training on the management of dental trauma. Concerning the management of tooth fracture, 138 respondents (85.8%) gave the appropriate management for fractured tooth. One hundred twenty-one (75%) of the respondents indicated that is very urgent to seek professional assistance if a permanent tooth is avulsed, but they had little knowledge on the correct media for transporting the avulsed tooth. Most teaches were unsatisfied with their level of knowledge for dental trauma and the majority were interested in having further education on the topic. The findings revealed that the level of knowledge of management of dental trauma (especially tooth avulsion) among school teachers in Ajman is inadequate, and education campaigns are necessary to improve their emergency management of dental injuries.

    Dental erosion currently stands as a great challenge for the clinician, regarding the diagnosis, identification of the etiological factors, prevention and execution of an adequate treatment. To evaluate the prevalence, severity, and associated factors on dental erosion in 11-16-years old. A cross sectional study was conducted among 2000 school children who were randomly selected. A questionnaire was given to the children that included personal demographic details and habit of consuming acidic foods and drinks. An index specific for dental erosion given by O Sullivan was used to assess every affected tooth. The values were subjected to chi-square test and multivariate logistic regression analysis. The prevalence of dental erosion was found to be 1.4%. Females (1.6%) were slightly more affected than males (1.3%). Public school children (2.1%) were found to be affected a little more than private children (0.7%). Chi square test showed significant association between type of school and erosion prevalence (p = 0.015). Most commonly affected teeth were lateral incisor (59.72%). The prevalence of dental erosion was found to be low when compared to various studies done all over the world.

    The aim of this study was to assess the level of tobacco dependence education offered by Italian dental hygiene programs. A fifty-question survey was mailed to the thirty-one active public and private dental hygiene programs in Italy during the 2008-09 academic year. The survey assessed faculty confidence in teaching tobacco treatment, which courses contained tobacco dependence content, the number of minutes spent on specific content areas, and the level of clinical competence that dental hygiene graduates should be able to demonstrate. Surveys were returned by sixteen programs for a response rate of 52 percent. Respondents indicated tobacco dependence education was included in clinic or clinic seminar (56 percent), periodontics (44 percent), oral pathology (31 percent), and prevention (19 percent). All programs reported including the effects of tobacco on general and oral diseases in courses. However, more in-depth topics received less curriculum time; these included tobacco treatment strategies (63 percent) and discussion of cessation medications (31 percent). Interestingly, 62 percent of the respondents indicated they expected dental hygiene graduates to demonstrate a tobacco treatment competency level of a moderate intervention or higher (counseling, discussion of medications, follow-up) rather than a brief intervention in which patients are advised to quit then referred to a quitline. The results of this study indicated that Italian dental hygiene students are not currently receiving adequate instruction in tobacco treatment techniques nor are they being adequately assessed. This unique overview of Italian dental hygiene tobacco dependence education provides a basis for further discussion towards a national competency-based curriculum.

    The current study investigated the attitudes and knowledge regarding diet and oral hygiene of parents with kindergarten children. The parents' statements were evaluated in terms of their socioeconomic background and were compared with the annual clinical examination of the children. The objective of the study was to assess the effectiveness of the school dental-health program and adapt it to today's societal needs. Of those who participated in the interview, 61% were Swiss, 16% were from former Yugoslavia or Turkey, and 12% each from the EU or other countries. Of the children examined, 39% already had caries, and 18% of those showed more than two lesions. The parents' knowledge correlated with the severity of the child's caries as well as with the parents' income, country of origin, and education. There was a correlation between the child's dental decay and lower income, as well as lower education and non-Swiss nationality of the parents. Parents with higher income and better education more often participated in the preschool's preventive program. Parents from former Yugoslavia or Turkey participated less frequently than parents from other countries. The study demonstrated that parents who especially needed instruction and prophylaxis are contacted too late or not at all through the dental-health program at kindergarten and that new approaches to prevention should be implemented to more effectively reach the parents.

    The burden of untreated tooth decay remains high and oral healthcare utilisation is low for the majority of children in South Africa. There is need for alternative methods of improving access to low cost oral healthcare. The mobile dental unit of the University of the Witwatersrand (Wits) has been operational for over 25 years, providing alternative oral healthcare to children and adults who otherwise would not have access. The aim of this study was to conduct a cost-analysis of a school based oral healthcare program in the Wits mobile dental unit. The objectives were to estimate the general costs of the school based program, costs of oral healthcare per patient and the economic implications of providing services at scale. In 2012, the Wits mobile dental unit embarked on a 5 month project to provide oral healthcare in four schools located around Johannesburg. Cost and service use data were retrospectively collected from the program records for the cost analysis, which was undertaken from a provider perspective. The costs considered included both financial and economic costs. Capital costs were annualised and discounted at 6 %. One way sensitivity tests were conducted for uncertain parameters. The total economic costs were R813.701 (US$76,048). The cost of screening and treatment per patient were R331 (US$31) and R743 (US$69) respectively. Furthermore, fissure sealants cost the least out of the treatments provided. The sensitivity analysis indicated that the Wits mobile dental unit was cost efficient at 25 % allocation of staff time and that a Dental Therapy led service could save costs by 9.1 %. Expanding the services to a wider population of children and utilising Dental Therapists as key personnel could improve the efficiency of mobile dental healthcare provision.

    The General Dental Council expects professionalism to be embedded and assessed through-out the undergraduate dental programme. Curricula need therefore to accommodate these recommendations. A stroll poll of UK dental schools provided a basis for understanding the current methods of teaching and assessing professionalism. All respondent schools recognised the importance of professionalism and reported that this was taught and assessed within their curriculum. For most the methods involved were largely traditional, relying on lectures and seminars taught throughout the course. The most common form of assessment was by grading and providing formative feedback after a clinical encounter. Whilst clinical skills and knowledge can perhaps be readily taught and assessed using traditional methods, those involved in education are challenged to identify and implement effective methods of not only teaching, but also assessing professionalism. A variety of standalone methods need to be developed that assess professionalism and this will, in turn, allow the effectiveness of teaching methods to be assessed.

    Undergraduate degree projects have currently been introduced into courses in the four Swedish dental schools. The rationale for research projects is that they enable students to develop research expertise skills and to show their ability to apply and develop knowledge relevant to professional practice. This paper reports a qualitative analysis of the curriculum documents and handbooks including the criteria used to assess the students' research reports. The aim was to investigate commonalities and differences in the design of degree projects between the four Swedish dental schools and to explore any inconsistencies within the documents. The documentary analysis was based on the constant comparison method. Four overarching themes emerged from the analysis: (i) developing scientific expertise, (ii) developing professional expertise, (iii) following rules and (iv) fostering creativity. The documents from the four dental schools revealed similar views on the purposes of the projects and provided similar assessment criteria. The students were requested to formulate an odontological problem, apply a relevant scientific method, analyse texts and empirical data, express critical reflections and write a short thesis. The students were free to choose topics. There were differences between the dental schools on the emphasis placed on practical uses of the projects and theoretical background of the projects. Two of the schools insisted on rigid rules of completing and writing the project yet paradoxically emphasised creativity. There were wide variations in the required length of the project report. The report may prove useful to dental schools in other countries who are about to design undergraduate research projects. © 2013 John Wiley & Sons A/S. Published by Blackwell Publishing Ltd.

    The electrochemical detection (ECD) is highly sensitive and can distinguish selectively electrochemically active materials. A sensitive and selective ECD is widely used for high-performance liquid chromatography (HPLC) of phenolic compounds, such as catecholamines, indoleamines and phenolic steroids in biological materials. In the present study, the HPLC/ECD system was applied for the simultaneous determination of various dental drugs, such as phenol, guaiacol, m-cresol, o-chlorophenol, p-chlorophenol, m-chlorophenol, eugenol, pyrogallol and resorcin. As a compromise between sensitivity and stability, the applied voltage was set at 1.2 V vs the reference electrode. These drugs were rapidly and selectively separated on a reversed-phase column using 10 mM acetate buffer (pH 4.0)-methanol (7:3, v/v) as a mobile phase. The detection limits of these drugs were determined to be 0.25 pmol per injection. These results imply that the HPLC/ECD method should be capable of determining these dental drugs with high sensitivity. The ECD was also applied to determine the enzyme activity. A highly sensitive and specific assay for alkaline and acid phosphatases and N-acetyl-beta-glucosaminidase in biological materials, such as plasma, saliva and bone, has been established. Phenol, formed enzymatically from the substrate, was determined by HPLC/ECD. The retention time of phenol was 7 min and no other peaks were observed. The method is rapid and sensitive with a detection limit for phenol of as little as 0.5 pmol. Thus, as little as 0.5 microliters of rat plasma or 10 microliters of human saliva is all that is required for both alkaline and acid phosphatase assays. The assay is accurate and reproducible. Using this assay, alkaline and acid phosphatase activities in human saliva and in rat saliva elicited by pilocarpine and isoproterenol were determined. It will be possible to apply this new assay method to extremely small biological samples. Thus, the application of the HPLC

    Alumina ceramics have been used in dental prosthesis because it is inert, presents higher corrosion and shear resistance when compared to metals, excellent aesthetic, and mechanical resistance. In this work it was produced an infrastructure material for applications in dental crowns, obtained by glass infiltration in alumina preform. Various oxides, among that, rare-earth oxide produced by Xenotime, were melted at 1450 deg C and heat treatment at 700 deg C to obtain the glass (REglass). The alumina was pre-sintered at 1100 deg C cut and machined to predetermine format (unidirectional indirect infiltration) and finally conducted to infiltration test. The alumina was characterized by porosity (Hg-porosity and density) and microstructure (SEM). The glass wettability in alumina was determined as function of temperature, and the contact angle presented a low value (θ<90 deg), showing that glass can be infiltrated spontaneously in alumina. The infiltration test was conducted at glass melting temperature, during 30, 60, 180, 360 minutes. After infiltration, the samples were cut in longitudinal section, ground and polished, and analyzed by XRD (crystalline phases), SEM (microstructure) and EDS (composition).The REglass presents higher infiltration height when compared to current processes (direct infiltration), and homogeneous microstructure, showing that it is a promising method used by prosthetics and dentists.

    Ferromagnetic alloys have been investigated as potential candidates for dental prosthesis applications in replacement for magnetic attachments made of noble and expensive alloys. Three stainless steels were investigated: 17-4 PH produced by powder injection (PIM), PM2000 obtained by mechanical alloying and oxide dispersion strengthened, and nickel free stainless steel 1802. In the in vitro cytotoxicity analysis, none of the three steels tested showed cytotoxic effects. The corrosion resistance of stainless steels was evaluated by electrochemical impedance spectroscopy (EIS) and anodic potentiodynamic polarization, in sodium phosphate buffer solutions (PBS) at 25 degree C. The AISI 316L stainless steel was also tested under the same conditions for comparison reasons. All the stainless steel samples were passive in the electrolyte used and presented susceptibility to pitting. The steel that showed the highest pitting resistance was the PM2000, whereas the 1802 had the lowest resistance to pitting among the tested ones. The Mott-Schottky diagrams suggested that the passive film over the surface of PM2000 steel is at least one decade less doped compared to 316L stainless steel, so less defective in its structure. The results pointed out to the PM2000 as a potential candidate for substitution of high cost magnetic alloys used in dental prosthesis. (author)

    It is important for dental schools to select students who will complete their degree and progress on to become the dentists of the future. The process should be transparent, fair and ethical and utilise selection tools that select appropriate students. The interview is an integral part of UK dental schools student selection procedures. This study was undertaken in order to determine whether different interview methods (Cardiff with a multiple mini interview and Newcastle with a more traditional interview process) along with other components used in selection predicted academic performance in students. The admissions selection data for two dental schools (Cardiff and Newcastle) were collected and analysed alongside student performance in academic examinations in Year 1 of the respective schools. Correlation statistics were used to determine whether selection tools had any relevance to academic performance once students were admitted to their respective Universities. Data was available for a total of 177 students (77 Cardiff and 100 Newcastle). Examination performance did not correlate with admission interview scores at either school; however UKCAT score was linked to poor academic performance. Although interview methodology does not appear to correlate with academic performance it remains an integral and very necessary part of the admissions process. Ultimately schools need to be comfortable with their admissions procedures in attracting and selecting the calibre of students they desire. © 2016 John Wiley & Sons A/S.

    The aim of this study was to assess the current status of mineral trioxide aggregate (MTA) as an educational material in dental schools in Turkey. A survey was sent to senior members of the endodontic departments of seventeen dental schools; fourteen responded. All respondents reported that they used MTA in their clinical practice, with apexification, perforations, retrograde fillings, and root resorptions being the most frequently occurring treatment procedures. All reported that information was given to students regarding MTA mainly as part of the curriculum. The third and fourth years were the periods when MTA was introduced to students in most of the schools. Twelve schools reported that students had the opportunity to observe procedures in which MTA was used, but students had the chance to use the material in a very minor proportion of the schools, mainly under the supervision of clinical instructors. Ten schools agreed that MTA should be included in the regular endodontic curriculum. Financial constraints seemed to be the predominant reason for those who answered this question negatively, followed by difficult handling properties and low radiopacity of the material. Within the limitations of this study, it can be concluded that ways should be sought to prevent financial difficulties from depriving dental students of the opportunity to receive information about contemporary methodologies such as MTA utilization.

    The aim of this study was to evaluate the socio-economic status of French undergraduate dental students. A 46-item questionnaire was completed by the dental students of six universities between 1992 and 1995. Subjects related to family background, housing, schooling, income, expenditure and participation in student life were investigated. A total of 1192 out of 1207 questionnaires were returned. Both genders had equal access to dental training. The average overall cost of the four last years of the dental course was 30,302 French francs and varied greatly between faculties, as did the number of hours spent at the faculty for lectures, tutorials and practicals, and clinical work. Overall, the majority of students came from a well off social background, and had a relatively high quality of life while a small minority received no support from their families. Thirty-four per cent of students had never worked. One third of students smoked and one third regularly consumed medication of some sort. A third did not participate in any sport. Only 25% students bought dental text books and 42% of the students reported using the library regularly. This study offers an accurate description of the socio-economic status of French dental students that could be used as a reference for comparable studies in other European countries.

    2013-06-01

    Pain constitutes a major reason patients pursue dental treatment. This article presents a novel curriculum to provide dental students comprehensive training in the management of pain. The curriculum's four-tier scaffold combines traditional and problem-based learning to improve students' diagnostic, pharmacotherapeutic, and assessment skills to optimize decision making when treating pain. Tier 1 provides underpinning knowledge of pain mechanisms with traditional and contextualized instruction by integrating clinical correlations and studying worked cases that stimulate clinical thinking. Tier 2 develops critical decision making skills through self-directed learning and actively solving problem-based cases. Tier 3 exposes students to management approaches taken in allied health fields and cultivates interdisciplinary communication skills. Tier 4 provides a "knowledge and experience synthesis" by rotating students through community pain clinics to practice their assessment skills. This combined teaching approach aims to increase critical thinking and problem-solving skills to assist dental graduates in better management of pain throughout their careers. Dental curricula that have moved to comprehensive care/private practice models are well-suited for this educational approach. The goal of this article is to encourage dental schools to integrate pain management into their curricula, to develop pain management curriculum resources for dental students, and to provide leadership for change in pain management education.

    To explore the possible association between weight class and prevalence of caries among children born 2005-2007, living in Nuuk, Greenland, at time of school entry. A cross-sectional register study based on data from electronic medical records(EMR) and oral health data from public health and dental care facilities. Data from routine examinations of children at time of primary school entry, including height and weight, were obtained from the EMRs. Dental charts recording oral health and caries were collected from public dental healthcare service. The prevalence of caries was calculated as the proportion of included children with dft score (decayed and/or filled non-permanent teeth) ≥1. 55%(373/681) had relevant data recorded in EMRs and dental charts, and could be included in the study. The prevalence of dental caries was 57.1%(213/373). The prevalence of caries increased with higher weight class,but no statistically significant trend was observed(p=0.063). Increasing prevalence of caries with increasing weight class was observed in this study. A linear trend could not be confirmed statistically. The high prevalence of caries and overweight indicate the need for continued focus on preventative initiatives and monitoring. A combined strategy targeting both caries and overweight may be considered.

Aself-developed questionnaire was used to assess the dietary habits of children. Acidic diet was considered a diet that has an acidic pH. The amount of consumption of acidic drinks and food per week was categorized into low consumption (1 - 7 times / week) and medium consumption (8 - 21 times / week). Chi-square test was applied to see any statistical difference between diet and tooth erosion at 95% CI. The results showed a high frequency of (46%) dental erosion in children, which was significantly higher (p dental erosion in children. Acidic diets need to be controlled in frequency to prevent dental erosion.

    Full Text Available Background: Anxiety toward dental treatment can cause people to delay or avoid seeking oral health care despite being in need of treatment. Therefore, recognizing such anxious patients and their appropriate management plays important aspects in clinical practice. Aim: The aim of this study was to investigate the level of dental anxiety (DA, factors affecting it, and anxiety toward dental extraction among adults seeking dental care to a dental school in Central India. Materials and Methods: The study sample consisted of 1360 consecutive patients aged 18–70 years. Participants completed a questionnaire while in the waiting room, which included the Modified Dental Anxiety Scale (MDAS to assess the level of DA. An additional item was included which asked participants to rate the anxiety felt on having a tooth extracted. Results: Among the study group, 65.1% were men and 34.9% were women. Based on the MDAS score, 41.8% of the participants were identified to be less anxious, 53.2% were moderately or extremely anxious, and 5% were suffering from dental phobia. Female participants and younger patients were more anxious (P = 0.0008. Patients who were anxious had postponed their dental visit (P = 0.0008. Participants who had negative dental experience were more anxious (P = 0.03. Nearly, 83% reported anxiety toward extraction procedure. A significant association was observed between anxiety toward dental extraction and the patients' gender (P = 0.03, age (P = 0.0007, education level (P = 0.03, employment status (P = 0.0006, income (P = 0.0007, self-perceived oral health status (P = 0.03, and their history of visit to dentist (P = 0.02. Conclusion: Majority of patients in this population revealed high levels of DA. Factors such as age, gender, education level, occupation, financial stability, and previous bad dental experience influence DA to various levels. Extraction followed by injection of local anesthetics and drilling of tooth provoked more anxiety.

    AIM: This paper reviews the demographic, academic and professional profile of Irish dental school faculty members. Faculty duties are explored. METHODS AND MATERIALS: Custom-designed questionnaires were distributed to faculty members for self-completion, adopting a \\'mixed-method\\' approach with quantitative and qualitative components. Response rate was 64.60%. RESULTS: Demographic profile reveals a male-dominated regime (64%). Males also occupy a disproportionate number of senior academic positions. The age profile mirrors international trends with 75% of staff over 40 and c.33% over 50, including 78% of professorial staff (p < 0.001). Dental school faculties are comprised of highly educated professionals with the following qualifications: 89% BDS, 43% FDS, 39% Masters, 16% Doctorates. Most (77%) have 10+ years of clinical experience, while 47% have over 20 years\\' experience. Clinical experience varied by age, rank (p < 0.001) and gender (p < 0.05). A review of contractual agreements and duties confirms the major role of part-time clinical staff in dental education, comprising the largest single group (48%) delivering the bulk of the clinical teaching. However, 54% of part-time clinical staff have less than five years teaching experience. This study also explores staff views of various faculty roles. CONCLUSIONS: This report provides a benchmark profile of Irish dental school faculty members. It reflects on the heavily skewed age groups of our current dental educators and the impending retirement of many senior academics. Educational organisations need to explore ways to make a career in dental education financially and sociologically attractive and provide adequate support for existing faculty to ensure their development during these challenging times.

    As part of the Basic Science Survey Series for Dentistry, members of the American Dental Education Association (ADEA) Physiology, Pharmacology, and Therapeutics Section surveyed directors of physiology courses in North American dental schools. The survey was designed to assess, among other things, faculty affiliation and experience of course directors, teaching methods, general course content and emphasis, extent of interdisciplinary (shared) instruction, and impact of recent curricular changes. Responses were received from forty-four of sixty-seven (65.7 percent) U.S. and Canadian dental schools. The findings suggest the following: substantial variation exists in instructional hours, faculty affiliation, class size, and interdisciplinary nature of physiology courses; physiology course content emphasis is similar between schools; student contact hours in physiology, which have remained relatively stable in the past fifteen years, are starting to be reduced; recent curricular changes have often been directed towards enhancing the integrative and clinically relevant aspects of physiology instruction; and a trend toward innovative content delivery, such as use of computer-assisted instruction, is evident. Data from this study may be useful to physiology course directors, curriculum committees, and other dental educators with an interest in integrative and interprofessional education.

    The objective of this study was to investigate if electronic patient records have utility in dental school strategic planning. Electronic health records (EHRs) have been used by all predoctoral students and faculty members at Nova Southeastern University's College of Dental Medicine (NSU-CDM) since 2006. The study analyzed patient demographic and caries risk assessment data from October 2006 to May 2011 extracted from the axiUm EHR database. The purpose was to determine if there was a relationship between high oral health care needs and patient demographics, including gender, age, and median income of the zip code where they reside in order to support dental school strategic planning including the locations of future satellite clinics. The results showed that about 51 percent of patients serviced by the Broward County-based NSU-CDM oral health care facilities have high oral health care needs and that about 60 percent of this population resides in zip codes where the average income is below the median income for the county ($41,691). The results suggest that EHR data can be used adjunctively by dental schools when proposing potential sites for satellite clinics and planning for future oral health care programming.

    Full Text Available Introduction: The purpose of this study was to assess the level of primary Knowledge among school staffs in Iran with regards to the immediate management of dental trauma. Methods: The data, from 160 participants, were collected using questionnaire, which surveyed staff’s background, attitude and knowledge of dental trauma management. Results: The total number of school staff who responded to all of the questions in the questionnaire was 138; the response rate was 86%. 91.3% of the participants had more than 10 years of teaching experience. Only 24 cases (17.4% have participated in training courses in regards to the dental trauma. 46.4% of the participants estimated their level of knowledge regarding the dental trauma as moderate and 42.8% as low and 7.2% without knowledge, however, 56.5% of them were highly interested in attending the training courses. Overall, the teachers’ knowledge on emergency management of the dental trauma cases presented in this study was deficient, especially in avulsed tooth management. Chi-square test showed that there was no statistically significant difference in the responses to the knowledge part of the questionnaire on age, gender, teaching experience and responsibility in school. Conclusion: The present report indicated the lack of knowledge among school staff on dental injuries managements. Organizing educational courses to improve the knowledge and awareness of school staff, as the first encounters of dental trauma in schools, seems necessary.

    The study assessed whether a healthy food policy implemented in one school, Yendarra Primary, situated in a socio-economically deprived area of South Auckland, had improved student oral health by comparing dental caries levels with students of similar schools in the same region with no such policy. Records of caries of the primary and adult teeth were obtained between 2007 and 2014 for children attending Yendarra, and were compared to those of eight other public schools in the area, with a similar demographic profile. Children were selected between the ages of 8 and 11 years. Linear regression models were used to estimate the strength of association between attending Yendarra school and dental caries. During the study period, 3813 records were obtained of children who attended dental examinations and the schools of interest. In a linear model, mean number of carious primary and adult teeth were 0.37 lower (95% confidence interval: 0.09-0.65) in Yendarra school children, compared to those in other schools, after adjustment for confounders. Pacific students had higher numbers of carious teeth (adjusted β coefficient: 0.25; 95% confidence interval: 0.03-0.46) than Māori. This nutrition policy, implemented in a school in the poorest region of South Auckland, which restricted sugary food and drink availability, was associated with a marked positive effect on the oral health of students, compared to students in surrounding schools. We recommend that such policies are a useful means of improving child oral health. © 2017 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

    How can library staff develop and promote a document delivery service and then expand the service to a wide audience? The setting is the library at the Indiana University School of Dentistry (IUSD), Indianapolis. A faculty survey and a citation analysis were conducted to determine potential use of the service. Volume of interlibrary loan transactions and staff and equipment capacity were also studied. IUSD Library staff created a desktop delivery service (DDSXpress) for faculty and then expanded the service to practicing dental professionals and graduate students. The number of faculty using DDSXpress remains consistent. The number of practicing dental professionals using the service is low. Graduate students have been quick to adopt the service. Through careful analysis of capacity and need for the service, staff successfully expanded document delivery service without incurring additional costs. Use of DDSXpress is continually monitored, and opportunities to market the service to practicing dental professionals are being investigated.

    Rates of tobacco use are increasing in the regions of Latin America and the Caribbean (LAC). Unfortunately, tobacco cessation education is not a standard component of the dental curriculum in LAC dental schools. The objective of this study was to identify the perceptions of LAC dental faculty members regarding the tobacco use prevention and cessation (TUPAC) competencies that should be addressed in the dental curricula. Dental deans and faculty completed a web-based questionnaire in Spanish, Portuguese, French, or English. The questionnaire contained 32 competencies grouped into the five A's (Ask, Advise, Assess, Assist, and Arrange) of tobacco cessation and six supplementary questions for identifying barriers to providing TUPAC education to dental students. Respondents indicated the degree to which they believed each competency should be incorporated into the dental curricula using a five-point Likert scale ("1" = strongly disagree to "5" = strongly agree). Responses were obtained from 390 faculty members (66 % South America, 18 % Mexico/Central America, 16 % the Caribbean). Of the respondents, 2, 12, and 83 % reported that smoking was allowed in clinical environments, other indoor environments, and outdoor environments of their dental schools, respectively. Mean importance ratings for each of the competencies were as follows: Ask (4.71), Advise (4.54), Assess (4.41), Assist (4.07), and Arrange (4.01). Overall, LAC dental educators agree that TUPAC training should be incorporated into the dental curricula. Assist and Arrange competencies were rated lower, relative to other competencies. Tobacco use among dental educators and high rates of on-campus smoking could potentially pose barriers to promoting cessation interventions in the LAC dental schools.

    To investigate the current state of genetics education at the Fourth Military Medical University (FMMU) and compare it with other dental schools of China. Detailed information about the history and current education status of Oral Genetics in the FMMU were collected and questionnaires were completed to acquire the feedback of twenty-seven students on the course. In the other thirty-five dental schools including the capitals of twenty-five provinces and four municipalities in China, information about the oral genetic course were collected by a telephone survey. The contents of survey included whether or not the Oral Genetic course is offered and some basic information about the curriculum (such as the content, hours, teachers' background and teaching methods). Among a total of thirty-six dental schools investigated, six of them (16.7%) offered the Oral Genetic course or related lectures/seminars. The length and contents of the curriculum vary among these schools. The FMMU offered the oral genetic curriculum both to undergraduates and graduated students. Their teachers had a broad range of backgrounds, such as dentistry, biology, genetics, and biochemistry. The students considered the Oral Genetics course to be helpful for their future professional careers. Genetic education in dentistry in China is still at a preliminary stage. More effort must be paid to spread the knowledge of Oral Genetics in China. In addition, domestic and international communications and networks for Oral Genetics should be set up in the near future.

    Harvard School of Dental Medicine, University of Maryland School of Dentistry, and the University of Rwanda (UR) are collaborating to create Rwanda's first School of Dentistry as part of the Human Resources for Health (HRH) Rwanda initiative that aims to strengthen the health care system of Rwanda. The HRH oral health team developed three management tools to measure progress in systems-strengthening efforts: 1) the road map is an operations plan for the entire dental school and facilitates delivery of the curriculum and management of human and material resources; 2) each HRH U.S. faculty member develops a work plan with targeted deliverables for his or her rotation, which is facilitated with biweekly flash reports that measure progress and keep the faculty member focused on his or her specific deliverables; and 3) the redesigned HRH twinning model, changed from twinning of an HRH faculty member with a single Rwandan faculty member to twinning with multiple Rwandan faculty members based on shared academic interests and goals, has improved efficiency, heightened engagement of the UR dental faculty, and increased the impact of HRH U.S. faculty members. These new tools enable the team to measure its progress toward the collaborative's goals and understand the successes and challenges in moving toward the planned targets. The tools have been valuable instruments in fostering discussion around priorities and deployment of resources as well as in developing strong relationships, enabling two-way exchange of knowledge, and promoting sustainability.

    The application of diamond coatings on cemented tungsten carbide (WC-Co) tools has been the subject of much attention in recent years in order to improve cutting performance and tool life in orthodontic applications. WC-Co tools containing 6% Co metal and 94% WC substrate with an average grain size of 1 - 3 microm were used in this study. In order to improve the adhesion between diamond and WC substrates it is necessary to etch cobalt from the surface and prepare it for subsequent diamond growth. Alternatively, a titanium nitride (TiN) interlayer can be used prior to diamond deposition. Hot filament chemical vapour deposition (HFCVD) with a modified vertical filament arrangement has been employed for the deposition of diamond films to TiN and etched WC substrates. Diamond film quality and purity has been characterized using scanning electron microscopy (SEM) and micro Raman spectroscopy. The performances of diamond-coated WC-Co tools, uncoated WC-Co tools, and diamond embedded (sintered) tools have been compared by drilling a series of holes into various materials such as human tooth, borosilicate glass, and acrylic tooth materials. Flank wear has been used to assess the wear rates of the tools when machining biomedical materials such as those described above. It is shown that using an interlayer such as TiN prior to diamond deposition provides the best surface preparation for producing dental tools.

    Dental caries is the most common chronic disease of childhood that interferes with normal nutrition intake, speech, and daily routine activities. Dental caries is a lifetime disease, and the highest priority risk group is school children. To assess the prevalence of dental caries and treatment needs among school going children of Chandigarh. A cross-sectional study was done among school going children of Chandigarh in the age group of 3-17 years. The subjects were selected from four randomly selected schools. All the children from the selected schools were examined. A total of 4493 subjects formed the sample size. Dentition status was assessed using dft index by Gruebbel for primary dentition and DMFT index by Klein, Palmer, Knutson for permanent dentition, respectively. Chi-square test was used to find an association between the study variables. Independent t-test and one-way ANOVA were used to compare the mean difference. Among the 4493 study subjects, caries prevalence was found to be 47.3%. Mean dft and DMFT score of the population was 1.06 ± 1.995 and 0.41 ± 1.022, respectively. When analyzing the treatment needs among various age groups 42.6% of the study subjects required oral prophylaxis and 45% required restorative procedures. Based on the findings, it can be concluded that high prevalence of caries was found in primary dentition than permanent dentition and most of the decayed teeth were untreated. This study emphasize the need for treating dental caries at its earliest possible stage and parents should be made aware of caries preventive measures for their children.

    Full Text Available Dentists are at risk of infectious diseases and dental offices can serve as a source of infection transmission if the infection control guidelines are not properly implemented. Adherence to infection control principles can help prevent disease transmission. This study sought to assess the level of knowledge and performance of dental students with regard to infection control principles in dental clinics of School of Dentistry, Mazandaran University of Medical Sciences. This study was conducted on 87 dental students. Data were collected using a 9-question questionnaire and a 16-item checklist. The data were analyzed using SPSS version 21 and descriptive statistics by calculation of mean and standard deviation (SD, t-test, Chi square test, Kruskal Wallis test and the Spearman’s correlation coefficient. Level of significance was set at P=0.05.Of subjects, 100% were wearing sterile gloves and changed them for each patient, collected and disposed wastes after examination or treatment of each patient, capped the needle after anesthetic injection and changed the dental suction tip; 94% were wearing a mask and changed it for each patient; 89% were wearing clean white coats. The level of knowledge of students was found to be moderate. Also, the performance of students with regard to infection control principles was found to be very good probably due to the rules and regulations set by the dental school departments.

    In this review, we summarize the current literature regarding the isolation and characterization of dental tissue-derived stem cells and address the potential of these cell types for use in regenerative cell transplantation therapy. Looking forward, platforms for the delivery of stem cells via scaffolds and the use of growth factors and cytokines for enhancing dental stem cell self-renewal and differentiation are discussed. We aim to understand the developmental origins of dental tissues in an effort to elucidate the molecular pathways governing the genesis of somatic dental stem cells. The advantages and disadvantages of several dental stem cells are discussed, including the developmental stage and specific locations from which these cells can be purified. In particular, stem cells from human exfoliated deciduous teeth may act as a very practical and easily accessibly reservoir for autologous stem cells and hold the most value in stem cell therapy. Dental pulp stem cells and periodontal ligament stem cells should also be considered for their triple lineage differentiation ability and relative ease of isolation. Further, we address the potentials and limitations of induced pluripotent stem cells as a cell source in dental regenerative. From an economical and a practical standpoint, dental stem cell therapy would be most easily applied in the prevention of periodontal ligament detachment and bone atrophy, as well as in the regeneration of dentin-pulp complex. In contrast, cell-based tooth replacement due to decay or other oral pathology seems, at the current time, an untenable approach.

    2015-06-01

    A 6-month pilot study was conducted to test the assumption that an interactive, contextualized tooth brushing education program would impact the oral hygiene of low income students. The intervention consisted of an educational program focused on tooth brushing that included interactive sessions with dental professionals and teachers. School 1 students received instruction, toothbrushes, and encouragement to brush their teeth daily after lunch. School 2 students received instruction only. School 3 students only received toothbrushes to remove plaque. Children in all 3 schools were examined by trained dental hygiene students who used plaque disclosing liquid to score the amount of plaque. A predictive correlational design was used to determine the extent that different intervention types and/or demographic/hygiene practices predicted differences in post intervention plaque level, once baseline plaque level was taken into account. A total of 254 first and second grade students in 3 public elementary schools in Miami participated in the study. Overall, mean plaque scores were significantly lower at the 6 month follow-up. Between-group comparisons of the mean follow-up scores, adjusted for the effect of the baseline scores, revealed greater but non-significant plaque reduction at School 1 compared to the other schools, and the presence of significant age and ethnic effects. The most intensive intervention instruction accompanied by repeated practice may lead to improved oral hygiene when compared to instruction alone, when oral hygiene practices and demographic characteristics are taken into account. Design changes intended to increase statistical power may help to explicate these effects. Copyright © 2015 The American Dental Hygienists’ Association.

    2014-07-01

    Setting up good infection control practices in educational institutions is crucial in shaping future health professionals. The implementation of standard precautions (SPs) in Iranian dental schools has not been explored qualitatively to identify barriers to good practice. Twelve focus group discussions and 8 semistructured interviews were conducted with students, residents, and staff members (n = 83) of the Shiraz University of Medical Sciences Dental School. The interview guide addressed performance, subjective norms, and behavioral control domains of SP-related behaviors. Thematic analysis was performed manually to identify barriers to SP practices. Proximal factors of poor SP adherence were a lack of knowledge and technical difficulties. These factors were compounded by intermediate factors in the work environment: lack of facilities, heavy workload, patient expectations, interprofessional conflicts, and lack of good role models. Two underlying distal factors were financial issues and unsupportive organizational culture. The social constructionism theory was useful in analyzing the situation and suggesting an educational approach as part of the solution. Complex and intertwined barriers of SP adherence were found in this dental school. A social construction approach may assist in addressing these problems by shifting the culture through education to construct a contextual new knowledge. Further research in medical sociology of SP practices would be useful. Copyright © 2014 Association for Professionals in Infection Control and Epidemiology, Inc. Published by Mosby, Inc.

    Dental panoramic tomography is the most frequent examination among 7-12-year olds, according to the Radiation Safety and Nuclear Authority of Finland. At those ages, dental panoramic tomographs (DPTs) are mostly obtained for orthodontic reasons. Children's dose reduction by trimming the field size to the area of interest is important because of their high radiosensitivity. Yet, the majority of DPTs in this age group are still taken by using an adult programme and never by using a segmented programme. The purpose of the present study was to raise the awareness of dental staff with respect to children's radiation safety, to increase the application of segmented and child DPT programmes by further educating the whole dental team and to evaluate the outcome of the educational intervention. A five-step intervention programme, focusing on DPT field limitation possibilities, was carried out in community-based dental care as a part of mandatory continuing education in radiation protection. Application of segmented and child DPT programmes was thereafter prospectively followed up during a 1-year period and compared with our similar data from 2010 using a logistic regression analysis. Application of the child programme increased by 9% and the segmented programme by 2%, reaching statistical significance (odds ratios 1.68; 95% confidence interval 1.23-2.30; p-value radiation safety of children during dental panoramic tomography. Segmented and child DPT programmes can be applied successfully in dental practice for children.

    Full Text Available Aim: The aim of this study is to determine the prevalence of dental caries in primary teeth among 4-6 years old school going children in the Namakkal District. Materials and Methods: The study covered a total of 850 school going children in a total of 26 schools in the Namakkal district of Tamil Nadu. The age group selected for this study ranged from 4 to 6 years of age. Each child was examined in their respective schools by one of the four calibrated examiners and decay, missing and filled teeth (dmft index was recorded along with demographic details. This study was done in September-October 2013 in a span of 1 month duration. Results: Of 850 children examined, 560 (65.88% children had dental caries. Mean dmft score was 2.86. Prevalence of dental caries was higher in boys (69.6% than in girls (61.5%. The untreated decay teeth accounted for 92.4%. Conclusion: The prevalence of dental caries among 4-6 years old children is high in the Namakkal district. The need for the creation of dental awareness among children and their primary caregivers is crucial and the need for developing immediate oral health promotion strategies including an increase in school dental health programs is recommended.

    Harvard School of Dental Medicine (HSDM) uses a hybrid problem-based approach to teaching in the predoctoral program. The objective structured clinical examination (OSCE) is a formative examination designed to assess the performance of students in the problem-based learning (PBL) curriculum. At HSDM three comprehensive examinations with OSCE components are administered during the third and fourth years of clinical training. The National Board Dental Examination (NBDE) Part II is taken in the final year of the predoctoral program. This study examines the association between the NBDE Part II and the comprehensive exams held at HSDM. Predoctoral students from the HSDM classes of 2005 and 2006 were included in this study. The outcome variable of interest was the scores obtained by students in the NBDE Part II, and the main independent variable of interest was the performance of students in the comprehensive exams (honors, pass, make-up exam to pass). The Mann-Whitney U-test was used to examine the association between the grades obtained in the each of the three comprehensive exams and the NBDE Part II scores. Multivariable linear regression analysis was also used to examine the association between the NBDE Part II scores and the comprehensive exam grades. The effect of potential confounding factors including age, sex, and race/ethnicity was adjusted. The results suggest that students who performed well in the comprehensive exams performed better on the NBDE Part II, even after adjusting for confounding factors. Future studies will examine the long-term impact of PBL on postdoctoral plans and career choices.

    Although the importance of empathy, rapport, and anxiety/pain awareness in dentist-patient relations has been well documented, these factors continue to be an issue with patients in many dental school clinics. The aim of this study was to develop an in-depth understanding of how patients at an urban, university-affiliated medical center and its dental school's clinic experienced oral health care and to generate ideas for improving the dental school's clinical curriculum and management of the clinic. Although patient satisfaction surveys are common, in-depth patient narratives are an underutilized resource for improving dental education. In-depth qualitative interviews were conducted with 20 uninsured or underinsured dental patients at these sites, and the results were analyzed using content analysis. Major phenomena that participants discussed were the importance of empathy and good rapport with their oral health providers and provider awareness of dental pain and anxiety. Many patients also discussed feeling dehumanized during dental visits. Based on their positive and negative experiences, the participants made suggestions for how oral health professionals can successfully engage patients in treatment.

    The aim of the two-year controlled trial was to evaluate the effectiveness of the 'Boosting Better Breaks' (BBB) break-time policy to reduce obvious decay experience and sugar snacking in a cohort of nine-year-old children attending intervention and control primary schools. A matched controlled prospective trial design. Children in Year 5 were invited with their parents/guardians to take part. The children were assessed at baseline and at 24-month follow-up. One hundred and eighty-nine children attended intervention schools and 175 attended control schools which were matched for socio-economic status (SES), school location and co-education status. The outcome variables were obvious decay experience and evidence of sugar snacks found in the children's rubbish bags. All children were asked to complete a questionnaire and keep evidence of the snacks they consumed starting from school-time break to when they retired for bed in a numbered and coded 'rubbish bag' on a specific collection day at baseline and 24-month follow-up. All children had a dental examination at baseline and 24-month follow-up. Sixty percent of children at baseline and all of the children at follow-up had at least one sugar snack in their rubbish bag. The most popular snacks at follow-up were sweets, chocolate, crisps and carbonated drinks. In the school environment children attending BBB policy schools had significantly lower mean scores for sugar snacks scores at baseline but equivalent mean sugar snacks scores at follow-up compared with children attending control schools. In the outside school environment there was no effect of school intervention on sugar snack scores. Decay into dentine at follow-up was predicted by school intervention status and evidence of sugar snacks consumption outside school and at home. The BBB break-time policy did not achieve its health promotion goals of promoting child dental health or encouraging children to adopt healthier dietary habits in school or in the wider

    Mandibular two-implant overdentures are considered the minimum standard of care for edentulous patients and provide an excellent performance, as well as satisfaction to the patients. Dental schools are required to promote the teaching of current treatment options in order to enable students to master state-of-the-art procedures. The purpose of this study was to examine how the theoretical and practical aspects of mandibular two-implant overdentures are taught in dental schools in North America. Data were collected via an online questionnaire that included questions regarding the theoretical and clinical courses, surgical procedure and imaging method. Of 75 schools, 36 responded to the survey. Almost all the schools teach the subject theoretically, but it is not mandatory for students to perform in most of the schools. Only a minority (23%) of the mandibular dentures made by students are implant-supported. Almost all of the schools (94%) use two implants to support overdentures, and Locator abutment is used almost exclusively. The prevalent imaging for the surgical procedure is CT scans, although 30% of the schools use panoramic radiograph. None of the schools loads the implants immediately after surgery. Some clear trends are apparent in the current survey: the use of two implants, no use of bar connectors and delayed loading of the implants. It is likely that graduates will not have sufficient clinical skills and will need continuing education to be familiar with the required procedures, both surgical and prosthetic. © 2016 John Wiley & Sons A/S.

    Dental hygiene activities were developed as part of a randomized clinical trial designed to assess the safety of low-level mercury exposure from dental amalgam restorations. Along with dental-hygiene clinical work, a community programme was implemented after investigators noticed the poor oral hygiene habits of participants, and the need for urgent action to minimize oral health problems in the study population. Clinical and community activity goal was to promote oral health and prevent new disease. Community activities involved participants and their fellow students and were aimed at providing education on oral health in a school environment. Dental hygienists developed clinical work with prophylaxis, sealants application and topical fluoride and implemented the community programme with in-class sessions on oral health themes. Twice a month fluoride mouthrinses and bi-annual tooth brushing instructional activity took place. Participation at dental-hygiene activities, sealed teeth with no need of restoration and dental-plaque-index were measures used to evaluate success of the programme for the participants. Improvement in dental hygiene is shown by the decrease in dental plaque index scores (P dental hygiene activities. Teachers became aware of the problem and included oral-health in school curricula. Dental hygiene activities have shown to be helpful to promote dental hygiene, promote oral health and to provide school-age children with education on habits that will be important for their future good health.

    The aim of this research was to identify short-term career aspirations and goals of final-year dental students at a London dental school and the perceived factors that influenced these aspirations. Two methods were used to collect data on final-year students' short-term career plans and influences. Qualitative data were collected through focus groups and analysed using 'framework methodology'. These findings informed a questionnaire survey of all students at the end of their final undergraduate year. Data were entered into and analysed using a statistical software package. Thirty-five students participated in focus groups, with recruitment continuing until data were saturated. Ninety per cent (n=126) of the total population (140) responded to the questionnaire survey; the majority were Asian (70%), female (58%), and aged 23 years (59%). Short-term professional expectations focused around 'achieving professional status within a social context', 'gaining professional experience', 'developing independence' and 'achieving financial stability'. 'Achieving financial stability' was ranked as the most important influence in decision-making about their career in the short term (77%), followed by 'balance of work and other aspects of life' (75%) and 'good lifestyle' (75%). Four out of ten intended to work towards membership of a Royal College and/or becoming a specialist. Proximity to family (81%) and friends (79%) was an important or very important influence on location in the short term. Asian students were significantly more likely to rate 'proximity to family' (p=0.042), working in an 'urban area' (p=0.001) and 'opportunities for private care' (p=0.043) of greater importance than their White counterparts. Short-term aspirations involve 'achieving professional status within a social context', and personal, social, professional and financial goals. Location of future practice was significantly associated with ethnicity.

    Traumatic dental injuries (TDIs) are widespread in the population and are a serious dental public health problem among children. Dental trauma may cause both functional and esthetic problems, with possible impacts on the patient's quality of life. To investigate teacher's knowledge and attitudes of Mathura city about emergency management of TDIs in children. A total of 352 teachers from total 23 schools of Mathura city were included in the study. Data were collected through a survey, which included a self-administered questionnaire. The questionnaire consisted of three major parts containing multiple-choice questions. Among the teachers 51.1% were males and 48.9% were females. Majority of the respondents, that is, 33.5% were between 31 and 40 years of age. Most respondents (34%) had more than 10 years of teaching experience. Majority of the teachers (39.2%) had educational qualification other than B.Ed. and M.Ed. degrees. Physical education teachers comprised the largest group of school teachers. Regarding knowledge and attitude, the teachers with 10-20 years of teaching experience, physical education teachers, and the teachers other than B.Ed. and M.Ed. qualifications had given more correct answers to the questions when compared with other groups. For the teachers having a low level of knowledge, there is a need for greater awareness to improve teachers' knowledge and attitudes related to the emergency management of TDIs in children by organizing educative and motivational programs.

    As part of the Basic Science Survey Series (BSSS) for Dentistry, members of the American Dental Education Association (ADEA) Anatomical Sciences Section surveyed faculty members teaching embryology and histology courses at North American dental schools. The survey was designed to assess, among other things, curriculum content, utilization of laboratories, use of computer-assisted instruction (CAI), and recent curricular changes. Responses were received from fifty-nine (88.1 percent) of the sixty-seven U.S. and Canadian dental schools. Findings suggest the following: 1) a trend toward combining courses is evident, though the integration was predominantly discipline-based; 2) embryology is rarely taught as a stand-alone course, as content is often covered in gross anatomy, oral histology, and/or in an integrated curriculum; 3) the number of contact hours in histology is decreasing; 4) a trend toward reduction in formal laboratory sessions, particularly in embryology, is ongoing; and 5) use of CAI tools, including virtual microscopy, in both embryology and histology has increased. Additionally, embryology and histology content topic emphasis is identified within this study. Data, derived from this study, may be useful to new instructors, curriculum and test construction committees, and colleagues in the anatomical sciences, especially when determining a foundational knowledge base.

    The aim of this study was to characterize the current status of predoctoral pediatric dentistry patient pools in U.S. dental schools and compare their status to that in 2001. A 2014 survey of school clinic-based and community-based dental patient pools was developed, piloted, and sent to pediatric predoctoral program directors in 57 U.S. dental schools via SurveyMonkey. Two follow-up contacts were made to increase the response rate. A total of 49 surveys were returned for a response rate of 86%. The responding program directors reported that their programs' patient pools had declined in number and had changed in character with more diversity and fewer procedures. They attributed the changes to competition, cost, and location of the dental school. The respondents reported that community-based dental education clinical sites continued to provide additional service experiences for dental students, with contributions varying by the nature of the site. A large number of the respondents felt that their graduates lacked some basic pediatric dentistry clinical skills and were not ready for independent practice with children. The results of this study suggest that the predoctoral pediatric dentistry patient pool has changed and general dentists may be graduating with inadequate experiences to practice dentistry for children.

    Trauma to primary and permanent teeth and their supporting structures is one of the most common dental problems seen in children. The prognosis of traumatized teeth depends on timely attention with prompt and appropriate treatment, which often relies on knowledge of the teachers who may be present at the place of accidents. Thus, the aim of this study was to evaluate via a questionnaire the knowledge level of primary school teachers in South Jaipur regarding dental trauma. Questionnaire survey. A self-designed questionnaire was administered to 300 primary school teachers from 20 randomly selected private and semi-aided schools of South Jaipur. A total of 278 teachers responded to the survey. The collected data were subjected to statistical analysis. It was found that most of the respondents had accepted poor knowledge regarding dental trauma, with a mean knowledge of 10.56 ± 2.58. This study highlighted inadequate knowledge regarding emergency management of traumatic dental injuries, and teachers felt the need for training in the management of dental trauma as part of their training program.

    Anecdotal evidence from clinical data in Johannesburg suggests that there is a high burden of dental caries among children with special health care needs (CSHCN) in Johannesburg. To determine the prevalence of dental caries and Unmet Treatment Needs in children with cerebral palsy, hearing, learning and mental disabilities attending special needs schools in Johannesburg and to compare these with data from the National Children's Oral Health Survey (NCOHS) METHODS: This cross-sectional analytical study comprised of 882 children attending five special needs schools in Johannesburg. Stratified randomised sampling of the participating schools was done and the schools were stratified by disability. Caries status was recorded via the dmft/DMFT index using WHO criteria and guidelines. The mean age of the participants was 10.5 years; with a caries prevalence of 27.55% and 33.56% in the primary and permanent dentition respectively. The highest unmet treatment need of 100% was found in the permanent dentition of the hearing impaired group followed by 90.77% in the primary dentition of the cerebral palsy group. In general no significant difference was found when the dmft/DMFT for CSHCN and NCOHS were compared except in the hearing impaired age groups four to five and six (both primary dentition) where significantly higher dmft scores (3.58 vs. 2.4; 3.85 vs. 2.9; p special health care needs had lower caries prevalence compared with the general population and higher unmet treatment needs regardless of the type of disability.

    ABSTRACT Dental arches areas with teeth presenting dentoalveolar ankylosis and replacement root resorption can be considered as presenting normal bone, in full physiological remodeling process; and osseointegrated implants can be successfully placed. Bone remodeling will promote osseointegration, regardless of presenting ankylosis and/or replacement root resorption. After 1 to 10 years, all dental tissues will have been replaced by bone. The site, angulation and ideal positioning in the space to place the implant should be dictated exclusively by the clinical convenience, associated with previous planning. One of the advantages of decoronation followed by dental implants placement in ankylosed teeth with replacement resorption is the maintenance of bone volume in the region, both vertical and horizontal. If possible, the buccal part of the root, even if thin, should be preserved in the preparation of the cavity for the implant, as this will maintain gingival tissues looking fully normal for long periods. In the selection of cases for decoronation, the absence of microbial contamination in the region - represented by chronic periapical lesions, presence of fistula, old unconsolidated root fractures and active advanced periodontal disease - is important. Such situations are contraindications to decoronation. However, the occurrence of dentoalveolar ankylosis and replacement resorption without contamination should neither change the planning for implant installation, nor the criteria for choosing the type and brand of dental implant to be used. Failure to decoronate and use dental implants has never been reported. PMID:29791693

    More than 200 different diseases may be transmitted from exposure to blood in the dental setting. The aim of this study is to identify possible faults in the crosscontamination chain control in a dental school clinic searching for traces of blood in the clinical contact surfaces (CCS) through forensic luminol blood test. Traces of invisible blood where randomly searched in CCS of one dental school clinic. Forty eight surfaces areas in the CCS were tested and the presence of invisible and remnant blood was identified in 28 (58.3%) items. We suggest that the luminol method is suitable for identifying contamination with invisible blood traces and this method may be a useful tool to prevent cross-contamination in the dental care setting.

    Case-based learning (CBL) is suggested as a key educational method of knowledge acquisition to improve dental education. The purpose of this study was to assess graduates from a patient-oriented, case-based learning (CBL)-based curriculum as regards to key competencies required at their professional activity. 407 graduates from a patient-oriented, case-based learning (CBL) dental curriculum who graduated between 1990 and 2006 were eligible for this study. 404 graduates were contacted between 2007 and 2008 to self-assess nine competencies as required at their day-to-day work and as taught in dental school on a 6-point Likert scale. Baseline demographics and clinical characteristics were presented as mean ± standard deviation (SD) for continuous variables. To determine whether dental education sufficiently covers the job requirements of physicians, we calculated the mean difference ∆ between the ratings of competencies as required in day-to-day work and as taught in medical school by subtracting those from each other (negative mean difference ∆ indicates deficit; positive mean difference ∆ indicates surplus). Spearman's rank correlation coefficient was calculated to reveal statistical significance (statistical significance plearning/working" (∆+0.08), whereas "Problem-solving skills" (∆-0.07), "Psycho-social competence" (∆-0.66) and "Business competence" (∆-2.86) needed improvement in the CBL-based curriculum. CBL demonstrated benefits with regard to competencies which were highly required in the job of dentists. Psycho-social and business competence deserve closer attention in future curricular development.

    Fluorescent emission of human teeth and dental calculus is important for the esthetic rehabilitation of teeth, diagnosis of dental caries, and detection of dental calculus. The purposes of this review were to summarize the fluorescence and phosphorescence of human teeth by ambient ultraviolet (UV) light, to investigate the clinically relevant fluorescence measurement methods in dentistry, and to review the fluorescence of teeth and dental calculus by specific wavelength light. Dentine was three times more phosphorescent than enamel. When exposed to light sources containing UV components, the fluorescence of human teeth gives them the quality of vitality, and fluorescent emission with a peak of 440 nm is observed. Esthetic restorative materials should have fluorescence properties similar to those of natural teeth. Based on the fluorescence of teeth and restorative materials as determined with a spectrophotometer, a fluorescence parameter was defined. As to the fluorescence spectra by a specific wavelength, varied wavelengths were investigated for clinical applications, and several methods for the diagnosis of dental caries and the detection of dental calculus were developed. Since fluorescent properties of dental hard tissues have been used and would be expanded in diverse fields of clinical practice, these properties should be investigated further, embracing newly developed optical techniques.

    Full Text Available Aim of the study: The paper addresses the use of dental age assessment methods based on radiographs in medico-legal practice. Different cases of practical application of the methods are presented including identification of human remains, dental age assessment in a living person and one archaeological case. Material and methods : The study material consisted of cases involving dental age assessment performed in the Department of Forensic Medicine, Poznan University of Medical Sciences in Poznan. Depending on the preliminary assessment of age, the Liversidge or the Kvaal et al. methods were applied. Dental age was estimated on the basis of available pantomograms. In the case of the living person, it was a radiograph supplied for expert evaluation. In the other cases, dental computed tomography was performed. Results : Dental age was successfully estimated in all of the cases. Various methods based on the analysis of X-ray images were applied. Dental age was shown to be correlated with skeletal age. Conclusions : The methods based on radiographs were demonstrated to be useful, and the results they yield are fully correlated with results of anthropological analyses.

    Each year the Association of American Veterinary Medical Colleges (AAVMC) conducts a survey after the close of the Veterinary Medical College Application Service (VMCAS) application. The survey provides a glimpse into applicant behavior surrounding the veterinary school application process. Additional survey questions probe into applicant financial behaviors, use of financial products and services, and pet ownership. This article examines the 2013 survey data from applicants who successfully completed the application, with a focus on applicant financial literacy and behaviors. Data from the study revealed a disconnect between applicants' perception of their ability to deal with day-to-day finances and their actual financial behaviors, particularly for first-generation college student applicants and applicants who are racially/ethnically underrepresented in veterinary medicine (URVM). Many applicants were not able to accurately report the average veterinary school graduate's student debt level, which suggests the potential need for better education about the costs associated with attending veterinary school.

The update information regarding dental health of school children of Sargodha district is required to plan community caries prevention programs and for better understanding of existing situation, and may improve longevity, treatment, and care. This cross sectional study was conducted in four randomly selected schools of Sargodha district, stratified by gender selected. Two well-trained dentists examined the oral cavities of children for dental caries, gingivitis, and calculus deposits. The sample consisted of children aged between 3-12 years. The overall prevalence rate of gingivitis, calculus, and dental caries was found as 14.5%, 14.3%, and 45.9% respectively. A significant association was found between DMFT score (p calculus (p calculus (p dental caries than children residing in rural areas. Incidence of gingivitis (p calculus, and dental caries in primary (p dental caries in primary teeth was found higher (p < 0.01) in children who brushed occasionally. Study also showed that none of the children ever visited dentist for treatment. The results emphasize the need for initiation of awareness programs to achieve 0 DMFT/df scores.

    In this chapter we describe the institutional and policy-level strategies that dental schools in the Pipeline, Profession, and Practice: Community-Based Dental Education program used to modify their admissions practices to increase the diversity of their student bodies. Schools developed and used clear statements recognizing the value of diversity. They incorporated recent U.S. Supreme Court rulings regarding educational diversity into their revised admissions practices; these rulings cited diversity as both a "compelling interest" and its use in only "narrowly tailored" circumstances. We make a case for admissions decisions based on a comprehensive evaluation that balances the quantitative and qualitative qualities of a candidate. It refutes the practice of overreliance on standardized tests by detailing the whole-file review process to measure merit and professional promise. Also described is a range of noncognitive variables (e.g., leadership, ability to sustain academic achievement with competing priorities, volunteerism, communication, social background, and disadvantaged status) that schools can take into consideration in admissions decisions. Admissions committees can tie this comprehensive review of candidates into the case for promoting cross-cultural understanding and enhanced competence to provide care to patients from diverse backgrounds. In addition, the chapter reviews the challenges schools face in developing admissions policies and procedures that reflect the university's mission for diversity. It addresses the importance of a diverse composition of the admissions committee. It also describes how tailored workshops and technical assistance for admissions committees can help schools improve their student diversity and how admissions committees can engage in a process of periodic review of their diversity objectives in relationship to the school's mission.

    There are currently inadequate data regarding the prevalence of dental caries and its associated variables, among Palestinian children. To determine the current prevalence of dental caries and related variables, among Palestinian children in East Jerusalem. A stratified sample of 286 East Jerusalem Palestinian children was selected, employing randomly chosen sixth grade clusters from three pre-selected socio-economic school groups. Dental caries was recorded according to WHO recommendations. Salivary flow, pH, buffer capacity and microbial parameters, were recorded according to previously employed methodologies. The mean level of caries experience, by DMFT, was 1.98 ± 2.05. This level was higher than those found among Israeli children, but lower than several other Middle Eastern countries. In uni-variate analysis, significant associations were revealed between caries and school categories, which indicated lower, middle and higher socio-economic position(SEP), mothers' employment, home densities, dental visits, tooth brushing, Streptococci mutans (SM), Lactobacilli (LB), and saliva pH. According to a linear logistic regression model, children learning in lower SEP schools, with higher SM levels and more acidic saliva, had a higher chance of experiencing dental caries. These findings should be considered in the planning of services and dental health care programs for Palestinian children.

    Comprehensive data on the characteristics and opinions of graduating dental students in Canada are lacking. Specifically, only minimal information is available on graduates' immediate career plans and factors that may influence their decisions regarding these plans. Our aim was to gather such data to allow better understanding of this issue and improve the design of future studies on this topic. The Career Development Committee at the school of dentistry, University of Alberta, designed a short survey to be administered to graduating students over 5 years to gain insight into their immediate career plans and opinions on career services at the school. Preliminary results from 2012-2014 are reported here. With a response rate of close to 90% (n = 99/111), the data reveal considerable differences in immediate career plans between the surveyed students and those in other schools in Canada and the United States. Of the students, 89% were planning to work in a general dental practice and only 9% were planning to enroll in advanced education, including general practice residency training. More research is needed to better understand the factors affecting career path decisions of students.

    Following a preliminary study indicating that at least 10 percent of single-unit crown temporary restorations failed in patients who received treatment by predoctoral students, a comprehensive examination of provisional crown failure was initiated to identify strategies to reduce the failure rate. For all provisionalized, natural tooth, single-unit crown preparations in University of North Carolina School of Dentistry predoctoral clinics for one year (N=1008), we noted tooth type, type of crown, student level, faculty coverage experience, treatment clinic, temporary material and luting agent, and retreatment (failure) of the provisional restoration. For failures, we also noted the stage of crown preparation at failure and the time since initial placement of the temporary. We analyzed these data using simple cross-tabs and logistic regression on need for retreatment (alpha =0.05). The failure rate was 18.75 percent (N=189). The median time to failure was twelve days; the 25(th) and 75(th) percentiles were six and twenty-six days. Significant risk factors, in order of odds ratio estimates, were molar tooth, second- or third-year student, and inexperienced faculty. Most provisional failures occurred during the final preparation phase of treatment. Provisional restoration failure is more frequent than was initially suspected from preliminary studies. Strategies for institutional intervention to reduce provisional restoration failure include greater attention to evaluating provisional crowns placed by inexperienced students (sophomores and juniors) and placing more emphasis on the retentiveness of provisional restorations reused following the final impression. Review of provisional evaluation procedures is also indicated for faculty who do not routinely supervise these procedures.

    Student-generated videos provide an authentic learning experience for students, enhance motivation and engagement, improve communication skills, and improve collaborative learning skills. This article describes the development and implementation of a student-generated video activity as part of a knowledge, observation, simulation, and experience (KOSE) program at the School of Dentistry, International Medical University, Kuala Lumpur, Malaysia. It also reports the students' perceptions of an activity that introduced first-year dental students (n=44) to clinical scenarios involving patients and dental team aiming to improve professional behavior and communication skills. The learning activity was divided into three phases: preparatory phase, video production phase, and video-watching. Students were organized into five groups and were instructed to generate videos addressing given clinical scenarios. Following the activity, students' perceptions were assessed with a questionnaire. The results showed that 86 percent and 88 percent, respectively, of the students agreed that preparation of the activity enhanced their understanding of the role of dentists in provision of health care and the role of enhanced teamwork. In addition, 86 percent and 75 percent, respectively, agreed that the activity improved their communication and project management skills. Overall, the dental students perceived that the student-generated video activity was a positive experience and enabled them to play the major role in driving their learning process.

    The aim of this study was to determine the validity of peer evaluation for team-based learning (TBL) classes in dental education in comparison with the term-end examination records and TBL class scores. Examination and TBL class records of 256 third- and fourth-year dental students in six fixed prosthodontics courses from 2013 to 2015 in one dental school in Japan were investigated. Results of the term-end examination during those courses, individual readiness assurance test (IRAT), group readiness assurance test (GRAT), group assignment projects (GAP), and peer evaluation of group members in TBL classes were collected. Significant positive correlations were found between all combinations of peer evaluation, IRAT, and term-end examination. Individual scores also showed a positive correlation with group score (total of GRAT and GAP). From the investigation of the correlations in the six courses, significant positive correlations between peer evaluation and individual score were found in four of the six courses. In this study, peer evaluation seemed to be a valid index for learning performance in TBL classes. To verify the effectiveness of peer evaluation, all students have to realize the significance of scoring the team member's performance. Clear criteria and detailed instruction for appropriate evaluation are also required.

    Students' views of their educational experience can be an important source of information for curriculum assessment. Although quantitative methods, particularly surveys, are frequently used to gather such data, fewer studies have employed qualitative methods to examine students' dental education experiences. The purpose of this study is to explore characteristics of effective learning experiences in dental school using a qualitative method. All third-year (seventy) and fourth-year (seventy) dental students enrolled in one midwestern dental school were invited to participate. Fifty-three dental students (thirty-five male and eighteen female; thirty-two third-year and twenty-one fourth-year) were interviewed using a critical incident interview technique. Each student was asked to describe a specific, particularly effective learning incident that he or she had experienced in dental school and a specific, particularly ineffective learning incident, for comparison. Each interview was audiotaped. Students were assured that only the interviewer and one additional researcher would have access to the tapes. Data analysis resulted in identification of key themes in the data describing characteristics of effective learning experiences. The following characteristics of effective learning experiences were identified: 1) instructor characteristics (personal qualities, "checking-in" with students, and an interactive style); 2) characteristics of the learning process (focus on the "big picture," modeling and demonstrations, opportunities to apply new knowledge, high-quality feedback, focus, specificity and relevance, and peer interactions); and 3) learning environment (culture of the learning environment, technology). Common themes emerged across a wide variety of learning incidents. Although additional research is needed, the characteristics of effective learning experiences identified in this study may have implications for individual course design and for the dental school

  16. A new method to extract dental pulp DNA: application to universal detection of bacteria.

    Directory of Open Access Journals (Sweden)

    Lam Tran-Hung

    Full Text Available BACKGROUND: Dental pulp is used for PCR-based detection of DNA derived from host and bacteremic microorganims. Current protocols require odontology expertise for proper recovery of the dental pulp. Dental pulp specimen exposed to laboratory environment yields contaminants detected using universal 16S rDNA-based detection of bacteria. METHODOLOGY/PRINCIPAL FINDINGS: We developed a new protocol by encasing decontaminated tooth into sterile resin, extracting DNA into the dental pulp chamber itself and decontaminating PCR reagents by filtration and double restriction enzyme digestion. Application to 16S rDNA-based detection of bacteria in 144 teeth collected in 86 healthy people yielded a unique sequence in only 14 teeth (9.7% from 12 individuals (14%. Each individual yielded a unique 16S rDNA sequence in 1-2 teeth per individual. Negative controls remained negative. Bacterial identifications were all confirmed by amplification and sequencing of specific rpoB sequence. CONCLUSIONS/SIGNIFICANCE: The new protocol prevented laboratory contamination of the dental pulp. It allowed the detection of bacteria responsible for dental pulp colonization from blood and periodontal tissue. Only 10% such samples contained 16S rDNA. It provides a new tool for the retrospective diagnostic of bacteremia by allowing the universal detection of bacterial DNA in animal and human, contemporary or ancient tooth. It could be further applied to identification of host DNA in forensic medicine and anthropology.

    Full Text Available Dental Caries affects approximately 90% of the world’s population. At present, the clinical treatment for dental caries is root canal therapy. This treatment results in loss of tooth sensitivity and vitality. Tissue engineering can potentially solve this problem by enabling regeneration of a functional pulp tissue. Dental pulp stem cells (DPSCs have been shown to be an excellent source for pulp regeneration. However, limited availability of these cells hinders its potential for clinical translation. We have investigated the possibility of using somatic mesenchymal stem cells from other sources for dental pulp tissue regeneration using a biomimetic dental pulp extracellular matrix (ECM incorporated scaffold. Human periodontal ligament stem cells (PDLSCs and human bone marrow stromal cells (HMSCs were investigated for their ability to differentiate towards an odontogenic lineage. In vitro real-time PCR results coupled with histological and immunohistochemical examination of the explanted tissues confirmed the ability of PDLSCs and HMSCs to form a vascularized pulp-like tissue. These findings indicate that the dental pulp stem derived ECM scaffold stimulated odontogenic differentiation of PDLSCs and HMSCs without the need for exogenous addition of growth and differentiation factors. This study represents a translational perspective toward possible therapeutic application of using a combination of somatic stem cells and extracellular matrix for pulp regeneration.

    2017-07-01

    Full Text Available Metal additive manufacturing (AM, especially selective laser melting (SLM, has been receiving particular attention because metallic functional structures with complicated configurations can be effectively fabricated using the technique. However, there still exist some future challenges for the fabrication of high-quality SLM products for dental applications. First, the surface quality of SLM products should be further improved by standardizing the laser process parameters or by appropriately post-treating the surface. Second, it should be guaranteed that dental SLM restorations have good dimensional accuracy and, in particular, a good marginal fit. Third, a definitive standard regarding building and scanning strategies, which affect the anisotropy, should be established to optimize the mechanical properties and fatigue resistance of SLM dental structures. Fourth, the SLM substructure’s bonding and support to veneering ceramic should be further studied to facilitate the use of esthetic dental restorations. Finally, the biocompatibility of SLM dental alloys should be carefully examined and improved to minimize the potential release of toxic metal ions from the alloys. Future research of SLM should focus on solving the above challenges, as well as on fabricating dental structures with “controlled” porosity.

    To evaluate the number of patients with dental implants who present to a dental school clinic for screening and to report the prevalence of peri-implant bone level change detected on digital panoramic radiographs of those subjects. Patient screening files for 9,422 patients over a 2-year period were examined to see how many patients presented with dental implants. Those patients with at least one implant were further evaluated by measuring the bone level on the mesial and distal sides of the implant using the screening radiograph. A total of 187 patients (2%) had at least one implant. In regard to implants, 423 were examined and 146 (33%) had no detectable bone loss defined as bone level below the top of the implant. When thresholds of bone loss were evaluated, 109 implants (25%) had ≥ 2 mm of bone loss on either the mesial or distal sides or both. The median bone loss was 1.74 mm for the 277 implants with detectable bone loss and 2.97 mm for the 109 implants that had ≥ 2 mm bone loss. Interestingly, patients who were ≥ 70 years of age had significantly (P = .03) more bone loss in the mandible compared with the maxilla, while patients who were 60 to 69 years of age had significantly greater loss in the maxilla. These data reveal that for patients presenting to the dental school for a screening over a 2-year period, 1.98% had one or more dental implants. Furthermore, those patients with implants had a minimum amount of bone loss as measured from the top of the implant.

    Objective: To determine the frequency of dental erosion in 12-14 years school children and its association with dietary habits. Study Design: Observational cross-sectional analytical study. Place and Duration of Study: Fatima Jinnah Dental College, Karachi, from January to June 2010. Methodology: School children aged between 12 - 14 years were included in this study. Dental erosion was detected by visual examination. Aself-developed questionnaire was used to assess the dietary habits of children. Acidic diet was considered a diet that has an acidic pH. The amount of consumption of acidic drinks and food per week was categorized into low consumption (1 - 7 times / week) and medium consumption (8 - 21 times / week). Chi-square test was applied to see any statistical difference between diet and tooth erosion at 95 percent CI. Results: The Results showed a high frequency of (46 percent) dental erosion in children, which was significantly higher (p < 0.001) in children with more acidic diet. Conclusion: This study highlights the impact of dietary habits on the prevalence of dental erosion in children. Acidic diets need to be controlled in frequency to prevent dental erosion. (author)

  2. The possible ocular hazards of LED dental illumination applications.

    2013-01-01

    The use of high-intensity illumination via Light-Emitting Diode (LED) headlamps is gaining in popularity with dentists and student dentists. Practitioners are using LED headlamps together with magnifying loupes, overhead LED illumination and fiber-optic dental handpieces for long periods of time. Although most manufacturers of these LED illuminators advertise that their devices emit "white" light, these still consist of two spectral bands--the blue spectral band, with its peak at 445 nm, and the green with its peak at 555 nm. While manufacturers suggest that their devices emit "white" light, spectral components of LED lights from different companies are significantly different. Dental headlamp manufacturers strive to create a white LED, and they advertise that this type of light emitted from their product offers bright white-light illumination. However, the manufacturing of a white LED light is done through selection of a white LED-type based on the peak blue strength in combination with the green peak strength and thus creating a beam-forming optic, which determines the beam quality. Some LED illuminators have a strong blue-light component versus the green-light component. Blue-light is highly energized and is close in the color spectrum to ultraviolet-light. The hazards of retinal damage with the use of high-intensity blue-lights has been well-documented. There is limited research regarding the possible ocular hazards of usage of high-intensity illuminating LED devices. Furthermore, the authors have found little research, standards, or guidelines examining the possible safety issues regarding the unique dental practice setting consisting of the combined use of LED illumination systems. Another unexamined component is the effect of high-intensity light reflective glare and magnification back to the practitioner's eyes due to the use of water during dental procedures. Based on the result of Dr. Janet Harrison's observations of beginning dental students in a

    Adair, P M; Burnside, G; Pine, C M

    2013-01-01

    To improve oral health in children, the key behaviours (tooth brushing and sugar control) responsible for development of dental caries need to be better understood, as well as how to promote these behaviours effectively so they become habitual; and, the specific, optimal techniques to use in interventions. The aim of this paper is to describe and analyse the behaviour change techniques that have been used in primary school-based interventions to prevent dental caries (utilizing a Cochrane systematic review that we have undertaken) and to identify opportunities for improving future interventions by incorporating a comprehensive range of behaviour change techniques. Papers of five interventions were reviewed and data were independently extracted. Results indicate that behaviour change techniques were limited to information-behaviour links, information on consequences, instruction and demonstration of behaviours. None of the interventions were based on behaviour change theory. We conclude that behaviour change techniques used in school interventions to reduce dental caries were limited and focused around providing information about how behaviour impacts on health and the consequences of not developing the correct health behaviours as well as providing oral hygiene instruction. Establishing which techniques are effective is difficult due to poor reporting of interventions in studies. Future design of oral health promotion interventions using behaviour change theory for development and evaluation (and reporting results in academic journals) could strengthen the potential for efficacy and provide a framework to use a much wider range of behaviour change techniques. Future studies should include development and publication of intervention manuals which is becoming standard practice in other health promoting programmes. © 2013 S. Karger AG, Basel.

    Full Text Available Introduction: The present study was aimed at evaluating common positioning errors on panoramic radiographs taken in the Radiology Department of Mashhad Dental School. Materials and methods: The study sample included 1,990 digital panoramic radiographs taken in the Radiology Department of Mashhad Dental School by a Planmeca Promax (Planmeca Oy, Helsinki, Finland, during a 2-year period (2010–2012. All radiographs, according to dentition and sex, were evaluated for positioning errors. Results: There were 1,927 (96.8% panoramic radiographs with one or more errors. While the number of errors in each image varied between one and five, most images had one error (48.4%. The most common error was that the tongue was not in contact with the hard palate (94.8%. "Open lips" was an error not seen in any patients. Conclusions:positioning errors are common in panoramic radiographies. The most common error observed in this study was a failure to place the tongue on the palate. This error and the other errors reported in this study can be reduced by training the technicians and spending little more time for patient positioning and more effective communication with the patients.

    2013-01-01

    Leadership is vital in all professions and organizations. Our purpose was to determine where in dental schools leadership is taught, and to what degree it is emphasized so that we could establish a base line from which to generate recommendations for best practices. Therefore we surveyed all US Deans of Academic Affairs in Dental Schools to determine where in the curriculum leadership is taught and emphasized. Our results showed that leadership training is delivered in many different parts of the curriculum, and at various levels. Generally, respondents indicated that leadership education is delivered either in the setting of practice management, community outreach or in public health settings. In some cases, specific training programs are dedicated specifically to leadership development. Thus several models for leadership development were identified showing design and flexibility to address regional and national needs. In the future it would be of value to assess the effectiveness of the different models and whether single or multiple pathways for leadership training are most beneficial. PMID:22659699

  7. Perspectives on the dental school learning environment: putting theory X and theory Y into action in dental education.

    Science.gov (United States)

    Connor, Joseph P; Troendle, Karen

    2008-12-01

    Theory X and Theory Y are terms coined by Douglas McGregor to express the belief that managers' behaviors are shaped by their assumptions about the motivation of their subordinates. The theories were applied to dental education in a Perspectives article published in the August 2007 issue of the Journal of Dental Education. This article explains how those seemingly contradictory theories can be reconciled using the concept of the "emotional bank account" introduced by Stephen Covey in The 7 Habits of Highly Effective People. Understanding the underlying concept of an emotional bank account helps dental educators to bridge the generation gap between instructors, born during the baby boom period of 1946-63, and dental students, born after 1980, who are referred to as "Generation Y" or "millennials."

    2013-10-01

    The International Dental Federation and World Health Organization have promoted the use of Atraumatic Restorative Treatment (ART) in modern clinical settings worldwide. In the United States, the practice of ART is not believed to be widely used, which may be a result of little attention given to ART training in predoctoral pediatric dentistry curricula in U.S. dental schools. This study investigated the extent of clinical and didactic instruction on ART provided in U.S. dental schools by surveying the predoctoral pediatric dentistry programs in 2010. Of the fifty-seven directors asked to complete the survey, forty-four responded for a response rate of 77 percent. Of these forty-four programs, 66 percent reported providing clinical training on ART, though only 14 percent provide this training often or very often. The types of ART training provided often or very often included interim treatment (18 percent) and single-surface cavities (14 percent) in primary teeth. However, ART was said to be rarely taught as a definitive treatment in permanent teeth (2 percent). Attitude was a major predictor, for clinical training provided and using professional guidelines in treatment decisions were associated with a positive attitude towards ART. These predoctoral pediatric dentistry programs used ART mainly in primary, anterior, and single-surface cavities and as interim treatment. As ART increases access of children to dental care, the incorporation of the ART approach into the curricula of U.S. dental schools should be facilitated by professional organizations.

    Full Text Available Context: Dental trauma has become an important attribute of dental public health. The primary requisite before actively dealing with such problems is to describe the extent, distribution, and associated variables with the specific condition. Aims: The aim of the present study was to assess the prevalence and distribution of traumatic dental injuries (TDI to anterior teeth among 3 to 13 years old Chidambaram school children. Settings and Design : A cross-sectional study was conducted. Data was collected through a survey form and clinical examination. Materials and Methods: A total of 3200 school children in the age group of 3-13 years were selected from 10 schools of Chidambaram, Tamilnadu. Information concerning sex, age, cause of trauma, number of injured teeth, type of the teeth, lip competence, terminal plane relationship and the molar relationship were recorded. Statistical Analysis Used: The statistical software EPIINFO (Version 6.0 was used for statistical analysis. In the present study, P≤0.05 was considered as the level of significance. Results: The trauma prevalence in the present study was 10.13%. Children with class I type 2 and mesial step molar relationship exhibited more number of dental injuries. Enamel fracture was the most common injury recorded. Only 3.37% of the children had undergone treatment. Conclusion: The high level of dental trauma and low percentage of children with trauma seeking treatment stresses the need for increased awareness in Chidambaram population.

    Digital tomosynthesis (DTS) is a limited-angle tomographic technique that provides some of the tomographic benefits of computed tomography (CT) but at reduced dose and cost. Thus, the potential for application of DTS to dental X-ray imaging seems promising. As a continuation of our dental radiography R and D, we developed an effective DTS reconstruction algorithm and implemented it in conjunction with a commercial dental CT system for potential use in dental implant placement. The reconstruction algorithm employed a backprojection filtering (BPF) method based upon optimal deblurring filters to suppress effectively both the blur artifacts originating from the out-focus planes and the high-frequency noise. To verify the usefulness of the reconstruction algorithm, we performed systematic simulation works and evaluated the image characteristics. We also performed experimental works in which DTS images of enhanced anatomical resolution were successfully obtained by using the algorithm and were promising to our ongoing applications to dental X-ray imaging. In this paper, our approach to the development of the DTS reconstruction algorithm and the results are described in detail.

    Background: Fluoride is a double edged sword. The assessment of dental caries and fluorosis in endemic fluoride areas will facilitate in assessing the relation between fluoride concentrations in water with dental caries, dental fluorosis simultaneously. Aim: The objective of the following study is to assess the dental caries and dental fluorosis prevalence among 12 and 15-year-old school children in Nalgonda district, Andhra Pradesh, India. Subjects and Methods: This was a cross-sectional study. Two stage cluster sampling technique was employed to select 20 schools from Nalgonda district. The oral examination of available 12 and 15-year-old children fulfilling the inclusion and exclusion criteria was carried out to assess dental caries and fluorosis. The examination was conducted by a single trained and calibrated examiner using the mouth mirror and community periodontal index probe under natural daylight. These areas were divided into four categories, low, medium, high and very high fluoride areas based on the fluoride concentration at the time of statistical analysis. The data was analyzed using Statistical Package for the Social Sciences version 16 (IBM, Chicago, USA). Results: The caries prevalence was less among 12-year-old children (39.9% [369/924]) compared with 15-years-old children (46.7% [444/951]). The prevalence was more among females (50.4% [492/977]) than males (35.8% [321/898]). The prevalence was more in low fluoride area (60.5% [300/496]) followed by very high fluoride area (54.8% [201/367]), high fluoride area (32.4% [293/904]) and medium fluoride area (17.6% [19/108]) in the descending order. The fluorosis prevalence increased with increasing fluoride concentration with no difference in gender and age distribution. Conclusion: Low fluoride areas require fluoridation or alternate sources of fluoride, whereas high fluoride areas require defluoridation. Defluoridation of water is an immediate requirement in areas with fluoride concentration of 4

    Chepang communities are one of the most deprived ethnic communities in Nepal. According to the National Pathfinder Survey, dental caries is a highly prevalent childhood disease in Nepal. There is no data concerning the prevalence of caries along with knowledge, attitude and oral hygiene practices among Chepang schoolchildren. The objectives of this study were to 1) record the prevalence of dental caries 2) report experience of dental pain 3) evaluate knowledge, attitude and preventive practices on oral health of primary Chepang schoolchildren. A cross sectional epidemiological study was conducted in 5 government Primary schools of remote Chandibhanjyang Village Development Committee (VDC) in Chitwan district. Ethical approval was taken from the Institutional Review Board within the Research Department of the Institute of Medicine (IOM) Tribhuvan University. Consent was obtained from parents for conducting clinical examination and administrating questionnaire. Permission was taken from the school principal in all schools. Data was collected using a pretested questionnaire on 131 schoolchildren aged 8-16-year- olds attending Grade 3-5. Clinical examination was conducted on 361 school children aged 5-16 -year-olds attending grade 1-5. Criteria set by the World Health Organization (1997) was used for caries diagnosis. The questionnaires, originally constructed in English and translated into Nepali were administered to the schoolchildren by the researchers. SPSS 11software was used for data analysis. Caries prevalence for 5-6 -year-old was above the goals recommended by WHO and Federation of Dentistry international (FDI) of less than 50% caries free children. Caries prevalence in 5-6-year-olds was 52% and 12-13-year-olds was 41%. The mean dmft/DMFT score of 5-6 -year-olds and 12 -13-year -olds was 1.59, 0.31 and 0.52, 0.84 respectively. The DMFT scores increased with age and the d/D component constituted almost the entire dmft/DMFT index. About 31% of 8-16-year

    The purpose of this study was to analyze traumatic dental injuries in children visiting the dental hospital emergency department in Samsun of Turkey, in the period from 2007 to 2011. Data of age, gender, causes of dental trauma, injured teeth, type of dental injuries, the application period, the dental treatments, and traumatic dental injuries according to the seasons were obtained from the records at dental hospital. Of all 320 patients with traumatic dental injury, 205 were boys and 115 were girls with a boys/girls ratio 1.78:1. Traumatic dental injury was observed more frequently in the 7-12 age groups: 52.5% in girls and 67.8% in boys. Falls are the major cause of traumatic dental injury in the age group 6-12 (51.4%). Sport activities are a common cause of traumatic dental injury in the 7-12 age group (34.2%). Patients visited a dentist within approximately 2 h (57.1%). The upper anterior teeth were subjected to trauma more frequently than the lower anterior teeth. The maxillary central incisors were the most commonly affected teeth, and the mandibular canins were the least affected teeth. In primary teeth, avulsion was the most common type of dental injury (23%); on the other hand, enamel fractures were the most common type of dental injury (30.6%) observed in permanent teeth. In the primary dentition, the most commonly performed treatments were dental examination and prescribing (70%). The most common treatment choices in permanent teeth were restoration and dental examination (49.7 and 15.8%, respectively). The results of the study show that the emergency intervention to traumatized teeth is important for good prognosis of teeth and oral tissues. Therefore, the parents should be informed about dental trauma in schools, and dental hospital physicians should be subjected to postgraduate training.

    There are numerous functions for laser in modern implant dentistry including surface treatment, surface coating, and implant manufacturing. As laser application may potentially improve osseointegration of dental implants, we systematically reviewed the literature for in vitro biological responses to laser-modified or processed titanium dental implants. The literature was searched in PubMed, ISI Web, and Scopus, using keywords "titanium dental implants," "laser," "biocompatibility," and their synonyms. After screening the 136 references obtained, 28 articles met the inclusion criteria. We found that Nd:YAG laser was the most commonly used lasers in the treatment or processing of titanium dental implants. Most of the experiments used cell attachment and cell proliferation to investigate bioresponses of the implants. The most commonly used cells in these assays were osteoblast-like cells. Only one study was conducted in stem cells. These in vitro studies reported higher biocompatibility in laser-modified titanium implants. It seems that laser radiation plays a vital role in cell response to dental implants; however, it is necessary to accomplish more studies using different laser types and parameters on various cells to offer a more conclusive result.

    In recent years, nanomaterials have been used in the medical-dental field as new alternative antimicrobial agents. Bismuth subsalicylate (BSS) has been used as an antimicrobial agent, but the effect of BSS in the form of nanoparticles (BSS-nano) as a potential antimicrobial agent has not been tested, in specific against bacteria responsible for periodontal disease. The aim of this study was to evaluate the antibacterial effect of BSS-nano against oral anaerobic bacteria and to assess the safety of BSS-nano by evaluating their cytotoxicity in human gingival fibroblast (HGF-1) cells. BSS-nano were synthesized by laser ablation and were previously physico-chemically characterized using in vitro assays. The antibacterial activity was measured using the tetrazolium-based XTT assay, and cytotoxicity was determined using lactate dehydrogenase (LDH) and MTS assays in HGF-1 cells. Transmission electron microscopy of HGF-1 exposed to BSS-nano was also performed. BSS-nano was shown to have a primary size of 4-22 nm and a polygonal shape. Among the tested bacterial strains, those with a greater sensitivity to BSS-nano (highest concentration of 21.7 μg ml-1) were A. actinomycetemcomitans, C. gingivalis, and P. gingivalis. BSS-nano at a concentration of 60 μg ml-1 showed low cytotoxicity (6%) in HFG-1 cells and was mainly localized intracellularly in acidic vesicles. Our results indicate that the concentration of BSS-nano used as an effective antibacterial agent does not induce cytotoxicity in mammalian cells; thus, BSS-nano can be applied as an antibacterial agent in dental materials or antiseptic solutions.

    Background: According to a pathfinder survey conducted by World Health Organization, dental caries is the single most common chronic childhood disease in Pakistan. The update information regarding dental health of school children of Sargodha district is required to plan community caries prevention programs and for better understanding of existing situation, and may improve longevity, treatment, and care. Methods: This cross sectional study was conducted in four randomly selected schools of Sargodha district, stratified by gender selected. Two well-trained dentists examined the oral cavities of children for dental caries, gingivitis, and calculus deposits. The sample consisted of children aged between 3-12 years. Results: The overall prevalence rate of gingivitis, calculus, and dental caries was found as 14.5 percentage, 14.3 percentage, and 45.9 percentage respectively. A significant association was found between DMFT score (p<0.001), gingivitis (p<0.01), and calculus (p<0.05) with the increase in age of children. More children living in urban area were detected with gingivitis (p<0.01), calculus (p<0.01), and dental caries than children residing in rural areas. Incidence of gingivitis (p<0.05), calculus, and dental caries in primary (p<0.001) and permanent teeth were found higher in those children who were not brushing their teeth. Experience of dental caries in primary teeth was found higher (p<0.01) in children who brushed occasionally. Study also showed that none of the children ever visited dentist for treatment. Conclusions: The results emphasize the need for initiation of awareness programs to achieve 0 DMFT/df scores. (author)

    Full Text Available Objectives. The objective of the present study was to assess shisha smoking among dental school students in Sharjah, United Arab Emirates (UAE. In addition, the role of suggested barriers and enabling factors in shisha smoking was also evaluated. Methods. A cross-sectional questionnaire-based survey was conducted at the College of Dental Medicine, University of Sharjah, between February and May 2016. The questions were adapted from previously published water pipe smoking studies. The collected data were analyzed to identify the relationship between shisha smoking and sociodemographic characteristics. Relevant questions were further categorized as enabling factors and barriers for shisha smoking. Results. Three enabling questionnaire items related to social environment were significantly associated with an increased risk of being a current smoker. The most powerful is peer pressure (“friends smoke shisha”, which increased the odds ratio of shisha smoking 11.3 times, followed by smoker sibling with increase in odd ratio by 4.52 times, then the belief of social acceptance with increase in odd ratio by 4.31 times. Conclusion. Shisha smoking is a serious problem among university students. Any intervention program in the university curricula should consider teaching students that shisha is no less risky than cigarettes and is addictive.

    This study was conducted with the purpose of assessing students' perceived learning experience at the time of graduation from a dental school in India. The domains appraised were undergraduate curriculum, student motivation and support services, institutional infrastructure, administrative services, components of teaching-learning programs, confidence level in carrying out specific clinical procedures, career choice, and postgraduate specialty preference after graduation. The authors surveyed forty-five dental interns at the end of their undergraduate course, a 100 percent response rate from the class. The results showed that over 95 percent of the graduates were satisfied with the curriculum and 60 to 95 percent reported that the various components of the teaching-learning process were adequate. Only 42 percent of the students were confident about setting up a practice; 65 percent wished to take a course on general dentistry; and 86 percent wanted to pursue postgraduate study. The principal conclusions were that although the program was satisfactory to the majority of participants, some areas of concern were identified that need improvement.

    The purpose of this observational study was to examine the association between body mass index and dental caries in Hispanic children. The research evaluated the influences of obesity, diet, parent education level, family acculturation, tooth brushing habits and gender as predictors of childhood caries. One examiner visually screened 177 third grade students from 3 elementary schools located in southern California's Coachella Valley. The children were screened for number of decayed, missing and filled teeth (DMFT). Height, weight, age and gender determined their body mass index. Primary caregivers completed a 30-point questionnaire for each participant. Multivariate analyses accessed the association between childhood dental caries and weight status and the influences of the measured variables. Results indicate that those in the obese category had a statistically significant lower rate of DMFT than did children in the healthy weight category. Overweight children showed a higher DMFT than healthy weight children but the results were not statistically significant. Covariates that significantly influenced this association were diet and socioeconomic status. Results from this study provide oral health professionals with baseline data and literature to support development of preventive programs for this population that concurrently address both obesity and oral health issues in scope and design.

    Integrated learning modules were introduced and baseline information was collected, in order to identify the expectations regarding e-learning. Furthermore, first formative evaluation of fourth-year dental students was conducted and the experience gained with summative online assessment was reported. Questionnaires designed by Infratest dimap (Berlin, Germany) were distributed to undergraduate students (n = 72) of the School of Dentistry. The fourth-year dental students went through a preliminary evaluation process. An online test was evaluated and compared with a traditional examination. Sixty-three questionnaires were returned. Sixty-five per cent of the students were already familiar with e-learning. All but one student owned at least one personal computer or laptop. Ninety-one per cent of the students expected positive effects from the integration of online modules. Enhanced flexibility regarding time and location as well as comfortable access to learning materials were mentioned most frequently. Ninety per cent of the students expected to achieve better results by finding it easier to understand learning materials produced with multimedia tools. Sixty per cent of the students feared technical complications when using an online platform. The online test was successfully performed. A formative evaluation process demonstrated agreement between expectations and first experiences with e-learning. Most students expect the quality of their studies to improve by implementation of e-learning. Students appreciating regularly updated learning materials particularly emphasise the importance of its visualisation. Online tests might be an option for student's self-performance rating.

    Dental caries among Iranian elementary school children aged 6-12 years continue to rise. To estimate treatment needs and guide health initiatives, current epidemiologic data are required. Such data are currently unavailable for dental health. The purpose of this study was to assess caries experience, dental plaque, and associated factors in elementary school-aged children from Iran. In this cross-sectional study, 988 elementary school children aged 7-12 years were selected by multistage cluster sampling. Dental caries was studied using the WHO criteria, dental plaque was examined according to O'Leary index. Data on parental education and occupation, living district, dental pain within the past year, and tooth brushing habits under parental supervision were collected through interviews based on questionnaire. The data were analyzed with descriptive statistics and logistic and linear regression. The mean (SD) age of the elementary school children was 9.64 (1.73) years. The highest dmft was seen in elementary school children aged 7-8 years 6.53 (4.37) and the highest DMFT and dental plaque was in 12 year olds recorded as 1.17 (1.77) and 51.97 (25.86), respectively. The proportion of decayed teeth in 7 years old elementary school based on dmft index was 80.36%, moreover, the proportion in 12 years old elementary school was 40.17% based on the DMFT index. Age, gender, and dental pain within the past year were significantly associated with DMFT and dmft. The odds of developing dental caries (DMFT) was 1.70 times higher in girls than in boys (p elementary school children in Hamadan were high and they were influenced by their sociodemographic factors. The associations found can be used as a helpful guide for planning accurate preventive programs for elementary school children in this region.

    Health services should be targeted toward those most in need of health care. Poor oral health disproportionately affects Māori, Pacific Island, and socioeconomically deprived New Zealanders of all ages, and oral health care services should be prioritised to such groups. In New Zealand, free oral health care is available for all children up to the age of 17. On the other hand, adult dental services are provided on a user-pays basis, except for a limited range of basic services for some adults, access to which varies regionally. This study investigated the extent of dental treatment inequalities among patients at New Zealand's only School of Dentistry. Data were audited for all treatments provided at the University of Otago Faculty of Dentistry from 2006 to 2011 for patients born prior to 1990. Ethnic and socioeconomic inequalities in the provision of dental extractions, endodontic treatment, crowns, and preventive care were investigated. Differences were expressed as the odds of having received one or more treatments of that type during the six-year period 2006 to 2011. Data were analysed for 23,799 individuals, of whom 11,945 (50.2%) were female, 1,285 (5.4%) were Māori and 479 (2.0%) were Pacific, 4,040 (17.0%) were of low socioeconomic status (SES), and 2,681 (11.3%) were beneficiaries or unemployed. After controlling for SES, age, and sex, Māori had 1.8 times greater odds of having had a tooth extracted than NZ European patients, while Pacific Islanders had 2.1 times the odds. Furthermore, after controlling for ethnicity, age, and sex, low-SES patients had 2.4 times greater odds of having had a tooth extracted than high-SES patients, and beneficiaries had 2.9 times the odds. Conversely, these groups were less likely to have had a tooth treated with a crown or endodontics or receive preventive care. Existing policies call for the reduction of inequalities. There is a need for a strategy to monitor changes in treatment inequality over time which includes

    The purpose of this survey was to identify the number and characteristics of caries risk assessment/treatment (CRA/ Tx) programs in U.S. dental schools in 2009 and compare the results to those of the 1998 survey. A survey of U.S. dental schools was conducted in 2009 using the same eleven-question survey instrument as in 1998. Results were analyzed using stratified random sampling and chi-square tests for six of the questions. Additionally, data from the other questions were directly compared. Two questions showed a statistically significant difference: an increase in programs supervised by one school department and the number of schools using CRA as a graduation requirement. Positive changes are occurring in the development of CRA/Tx programs in U.S. dental schools. A wide variety of approaches to teaching this subject, including use of terminology and treatment philosophies, is evident. The evolution of this subject has been slow and varied over the past eleven years. Changing from a mainly surgical approach model to a medical model is occurring, but a more integrated method is needed to clarify terminology, diagnosis, treatment, and communications with researchers, clinicians, teachers, patients, and third-party payers.

    Faculty members are expected to write high-quality multiple-choice questions (MCQs) in order to accurately assess dental students' achievement. However, most dental school faculty members are not trained to write MCQs. Extensive faculty development programs have been used to help educators write better test items. The aim of this pilot study was to determine if a short workshop would result in improved MCQ item-writing by dental school faculty at one U.S. dental school. A total of 24 dental school faculty members who had previously written MCQs were randomized into a no-intervention group and an intervention group in 2015. Six previously written MCQs were randomly selected from each of the faculty members and given an item quality score. The intervention group participated in a training session of one-hour duration that focused on reviewing standard item-writing guidelines to improve in-house MCQs. The no-intervention group did not receive any training but did receive encouragement and an explanation of why good MCQ writing was important. The faculty members were then asked to revise their previously written questions, and these were given an item quality score. The item quality scores for each faculty member were averaged, and the difference from pre-training to post-training scores was evaluated. The results showed a significant difference between pre-training and post-training MCQ difference scores for the intervention group (p=0.04). This pilot study provides evidence that the training session of short duration was effective in improving the quality of in-house MCQs.

    The fifty-five-item Diligence Inventory for Higher Education (DI-HE) was applied to a new subject group--190 dental students. After item and factor analysis, a fifty-item (four subscale) inventory best reflected this group. The DI-HE's split half reliability was 0.81 (p < 0.001), the reliability coefficient for the pre- and post-test was 0.68 (p < 0.01), and the correlation coefficient alpha was 0.90. The DI-HE scores were high, with no statistical differences among the four classes. Overall, significant relationships were found between grade point averages (GPAs) and DI-HE total and subscale scores, with r values as high as 0.44. While female students' DI-HE scores were significantly higher (p = 0.023) than male students' scores, no correlations between DI-HE scores and GPAs for females were found. The results suggest that DI-HE may be useful for assessment purposes in professional education.

    The interaction of lasers with the hard structures of the teeth, has found the excess of heat as a problem for its utilization. This study analyzes, in vitro, the interaction of the ultrashort pulse laser of Ti:safire (830 nm) with the bovine dental enamel. The system consisted in one main oscillator integrated with an amplifier (CPA). The pulses extracted before the temporal compression inside the amplifier had 30 ps, 1000 Hz and ∼1 mJ. The pulses extracted after the compression had 60 fs, 1000 Hz and ∼0,7 mJ. The M 2 was 1,3, the focal lens 2,5 cm, the focal distance 29,7 and a computerized translation stage x,y,z. We evaluated the amount of tissue removed per pulse,the resulting cavities and the surrounding tissues not irradiated, under OM and SEM. The fluency was the major factor for differentiating the two regimens studied, therefore, the intensity was not so important as we expected in this process. We found: one ablation region in 'cat tongue', one ablation length, one fluency ∼0,7 J/cm 2 for 30 ps and ∼0,5 J/cm 2 for 60 fs (50% of high speed burr), smooth edge for 30 ps and high precision of the sharp edge cut of submicrometric order for 60 fs.

    The elemental composition of healthy and diseased teeth from 25 South Australian children have been determined using thick target PIXE analysis. Different dental hard tissues, namely enamel, dentine, cementum and the amelodentinal junction, were analysed independently. A number of elements, Na, Mg, Al, P, S, Cl, Ca, V, Cr, Mn, Fe, Ni, Cu, Zn, Sr and Pb have been detected, and their concentrations measured. The concentrations of some of the elements were found to very considerable between: (a) healthy and diseases teeth, (b) teeth of the same type, and (c) different parts of the same tooth. Attemps have been made to correlate the concentrations of the various elements with the health of the teeth. In a pilot study, PIXE has also been applied for Pb analysis in the teeth of a few mentally retarded children. The teeth of all the children, with the exception of one who was suffering from Downe's syndrome, were found to contain appreciable amounts of lead. It is suggested that PIXE would provide a more convenient and accurate form of analysis than destructive chemical methods, for correlation Pb in children's teeth with their mental abilities. (orig.)

    Objective: To determine the prevalence of dental caries and its relationship with dental fluorosis, oral health behaviour and dietary behaviour among 12-year school children in moderate-fluoride drinking water community in Quetta, Pakistan. Study Design: Cross-sectional study. Place and Duration of Study: Government and private schools of Quetta, from November 2012 to February 2013. Methodology: A total of 349 children aged 12-year from 14 randomly selected schools were included. The data collection was done on questionnaire designed for children. Dental caries status was examined by using WHO criteria. Result: Dental caries was found in 81 children (23.2 percent) with mean DMFT 0.61. Boys had 1.6 times more chance to have dental caries than girls. Dental fluorosis was found in 63.6 percent of children with majority of moderate degree (50.5 percent). Dental fluorosis status was found significantly associated with dental caries status in children. The children who had mild, moderate and severe fluorosis, had 4 times more chances to develop caries than those who did not have fluorosis. There was no significant association between children's caries status and use of paste, brushing habit, miswak, and visit to the dentist. The use of pastries and juices had a direct relation with the children's dental caries status. Conclusion: Dental caries in children of Quetta is not so much frequent as compared to the fluoride deficient countries. However, the high prevalence of moderate dental fluorosis and consumption of pastries and juices resulted in dental caries. (author)

    Custom ceramic structures possess significant potentials in many applications such as dentistry and aerospace where extreme environments are present. Specifically, highly customized geometries with adequate performance are needed for various dental prostheses applications. This paper demonstrates the development of process and post-process parameters for a dental porcelain ceramic material using binder jetting additive manufacturing (AM). Various process parameters such as binder amount, drying power level, drying time and powder spread speed were studied experimentally for their effect on geometrical and mechanical characteristics of green parts. In addition, the effects of sintering and printing parameters on the qualities of the densified ceramic structures were also investigated experimentally. The results provide insights into the process-property relationships for the binder jetting AM process, and some of the challenges of the process that need to be further characterized for the successful adoption of the binder jetting technology in high quality ceramic fabrications are discussed.

    Full Text Available Background: Fluorosis is one of the common but major emerging areas of research in the tropics. It is considered endemic in 17 states of India. However, the Cuddalore district of Tamil Nadu is categorised as a fluorosis non-endemic area. But clinical cases of dental fluorosis were reported in the field practice area of Department of Community Medicine, Rajah Muthiah Medical College, Annamalai University, Chidambaram. Since dental fluorosis has been described as a biomarker of exposure to fluoride, we assessed the prevalence and severity of dental fluorosis among primary school children in the service area. Materials and Methods: Children studying in six primary schools of six villages in the field practice area of Rural Health Centre of Faculty of Medicine, Annamalai University, Chidambaram, were surveyed. Every child was clinically examined at the school by calibrated examiners with Dean′s fluorosis index recommended by WHO (1997. Chi-square test, Chi-square trend test and Spearman′s rank correlation coefficient test were used for statistical analysis. Results: Five hundred and twenty-five 5- to 12-year-old school children (255 boys and 270 girls were surveyed. The overall dental fluorosis prevalence was found to be 31.4% in our study sample. Dental fluorosis increased with age P < 0.001, whereas gender difference was not statistically significant. Aesthetically objectionable dental fluorosis was found in 2.1% of the sample. Villages Senjicherry, Keezhaperambai and Kanagarapattu revealed a community fluorosis index (CFI score of 0.43, 0.54 and 0.54 with 5.6%, 4.8% and 1.4% of objectionable dental fluorosis, respectively. Correlation between water fluoride content and CFI values in four villages was noted to be positively significant. Conclusion: Three out of six villages studied were in ′borderline′ public health significance (CFI score 0.4-0.6. A well-designed epidemiological investigation can be undertaken to evaluate the risk factors

    Nanomaterials are defined as materials with one or more external dimensions with a size of 1-100 nm. Such materials possess typical nanostructure-dependent properties (eg, chemical, biological, optical, mechanical, and magnetic), which may differ greatly from the properties of their bulk counterparts. In recent years, nanomaterials have been widely used in the production of dental materials, particularly in light polymerization composite resins and bonding systems, coating materials for dental implants, bioceramics, endodontic sealers, and mouthwashes. However, the dental applications of nanomaterials yield not only a significant improvement in clinical treatments but also growing concerns regarding their biosecurity. The brain is well protected by the blood-brain barrier (BBB), which separates the blood from the cerebral parenchyma. However, in recent years, many studies have found that nanoparticles (NPs), including nanocarriers, can transport through the BBB and locate in the central nervous system (CNS). Because the CNS may be a potential target organ of the nanomaterials, it is essential to determine the neurotoxic effects of NPs. In this review, possible dental nanomaterials and their pathways into the CNS are discussed, as well as related neurotoxicity effects underlying the in vitro and in vivo studies. Finally, we analyze the limitations of the current testing methods on the toxicological effects of nanomaterials. This review contributes to a better understanding of the nano-related risks to the CNS as well as the further development of safety assessment systems.

    To compare the academic performance of graduate-entry and direct school leavers in an undergraduate dental programme. This study examined the results of students in applied dental knowledge (ADK) progress tests conducted during two academic years. A mixed model analysis of variance (ANOVA) was conducted to compare the performance of graduate-entry and direct school leavers. ADK was treated as a repeated measures variable, and the outcome variable of interest was percentage score on the ADK. The results show statistically significant main effects for ADK [F (1,113) = 61.58, P < 0.001, η 2 p = 0.35], Cohort [F (1,113) = 88.57, P < 0.001, η 2 p = 0.44] and Entry [F (1,113) = 11.31, P = 0.001, η 2 p = 0.09]. That is, students do better on each subsequent test (main effect of ADK), students in later years of the programme perform better than those in earlier years (main effect of cohort), and graduate-entry students outperform direct school leavers. This is the first study to explore the differences in the academic performance of graduate-entry and direct school leavers in an undergraduate dental programme. The results show that the academic performance of graduate students was better than the direct school leavers in years 2 and 3. Further research is required to compare the performance of students longitudinally across the entire duration of undergraduate dental programmes and evaluate whether this difference persists throughout. © 2016 John Wiley & Sons A/S.

    2014-11-01

    One of the ways dental education is changing the way it is preparing the next generation of learners is through efficient utilization of interactive social media. Social media, which facilitates interaction and sharing of new ideas, is being utilized to educate students, residents, and faculty. Unfortunately, as with most improvements in technology, there are growing pains. Faculty, student, and patient interaction on social media platforms, such as Facebook and Twitter, can lead to inappropriate or embarrassing situations. Striking the appropriate balance between free speech rights of students and faculty and the need for colleges and universities to have efficient operations is often left to the judicial system. The concepts of free speech and contract law and how each is applied in educational settings should be understood by students, faculty, and administrators. This article provides a review of legal cases that led to current social media policies, as well as present-day cases that exemplify the application of these principles, to help dental educators gain a greater understanding of the boundaries of protected speech. It also provides a set of sample guidelines for communicating through these media.

    The purpose of this study was to increase our understanding of the impact of Health Information Technology Systems (HITS) on dental school users when the systems are integrated into chair-side patient care. We used qualitative research methods, including interviews, focus groups, and observations, to capture the experiences of HITS users at a single institution. Users included administrators, clinical faculty members, predoctoral students, support staff, and residents. The data were analyzed using a grounded theory approach, and nine themes emerged: 1) HITS benefits were disproportionate among users; 2) communicating about the HITS was challenging; 3) users experienced a range of strong emotions; 4) the instructor persona diminished; 5) there were shifts in the school's power structure; 6) allocation of end-users' time shifted; 7) the training and support needs of end-users were significant; 8) perceived lack of HITS usability made documentation cumbersome for clinicians; and 9) clinicians' workflow was disrupted. HITS integration into patient care impacts the work of all system users, especially end-users. The themes highlight areas of potential concern for implementers and users in integrating a HITS into patient care.

    Many students have paid employment while studying. In the Netherlands, the Individual Health Care Professions Act (IHCP Act) allows dental hygiene students to work under certain conditions in a dental practice. The aim of the study was to determine how many dental hygiene students have part-time job employment in dental practice and which professional tasks they carry out. We also asked the dental hygiene students their opinion of the IHCP Act. All the enrolled dental hygiene students (n = 341) at a School of Health in the Netherlands received a questionnaire by email. The response was 52% (176 students). Of the responding students, 75% had paid employment in addition to their study. A proportion of the students (35%) worked in a dental practice. The median number of hours worked per week was eight. Study year, age and prior education were positively related to working part-time in dental practice. Activities frequently performed were giving oral hygiene instruction, fluoride applications, scaling and root planning, providing chair side assistance and giving local anaesthesia. Although the self-reported knowledge about the IHCP Act was high, almost half of the students expressed the need for more detailed legal information. Many dental hygiene students work in a dental practice, taking over a number of tasks usually performed by the dentist. More information in the dental hygiene curriculum about the requirements of the IHCP Act seems desirable.

    Full Text Available Purpose: The purpose of this study was to investigate medical school applicants’ involvements in extracurricular activities including medical volunteering/community services, nonmedical community services, club activities, leadership role, and research. Methods: Extracurricular characteristics were compared for 448 applicants (223 males and 225 females who applied to Kangwon Medical School in 2013 to 2014. Frequency analysis, chi-square test, and simple correlation were conducted with the collected data. Results: The 448 applicants participated in medical volunteer/community services (15.3%, nonmedical community services (39.8%, club activities (22.9%, club officials (10%, and research (13.4%. On average, applicants from foreign universities participated in 0.9 medical volunteer/community service, 0.8 nonmedical community service, 1.7 club activities, and 0.6 research work. On the other hand, applicants from domestic universities reported 0.2 medical volunteer/community service, 1.0 nonmedical community service, 0.7 club activity, and 0.3 research. Conclusion: Involvement in extracurricular activities was extensive for medical school applicants. Participation in extracurricular activities differed between applicants from foreign and domestic universities. Females consistently reported greater participation in extracurricular activities than males. The data can be helpful for admission committees to recruit well-rounded applicants and compare between applicants with similar academic backgrounds.

    Integration is a key concern in discipline-based undergraduate dental curricula. Therefore, this study compared feedback on integration from students who participated in different instructional designs in a Comprehensive Patient Care course. The study was conducted at the University of Pretoria (2009-2011). Third-year cohorts (Cohorts A, B and C) participated in pre-clinical case-based learning, whilst fourth-year cohorts (Cohorts D and E) received didactic teaching in Comprehensive Patient Care. Cohorts A, D and E practised clinical Comprehensive Patient Care in a discipline-based clinic. Cohort B conducted their Comprehensive Patient Care patient examinations in a dedicated facility supervised by dedicated faculty responsible to teach integration. Students had to indicate on visual analogue scales whether the way they were taught at the school helped them to integrate knowledge from the same (horizontal integration) and preceding (vertical integration) year of study. The end-points of the scales were defined as 'definitely' and 'not at all'. Analysis of variance (ANOVA) was employed to measure the differences between cohorts according to the year of study. Third-year case-based learning cohorts rated the horizontal integration close to 80/100 and vertical integration ranging from 64 to 71/100. In year four, Cohort B rated vertical and horizontal integration 9-15% higher (ANOVA, P horizontal integration 11-18% higher (ANOVA, P integration in the discipline-based undergraduate dental curriculum. © 2016 John Wiley & Sons A/S.

    To investigate if patients with periodontitis attending the Dental School in Huddinge, Sweden presented with more signs of systemic diseases, such as cardiovascular disease, diabetes mellitus and respiratory diseases, compared to healthy and gingivitis patients. In this retrospective study, dental charts were examined where the periodontal diagnoses of patients were known. A total of 325 patients with severe periodontitis and 149 patients without periodontitis, born 1928 to 1968, were identified. Diagnosis regarding the systemic diseases was self-reported. Odds ratios for cardiovascular diseases, diabetes mellitus and respiratory diseases were calculated with a logistic regression model that was adjusted for age, gender and smoking. It was observed that more cases of periodontitis were found in older individuals than the controls (61.7 vs 56.2 years; P < 0.001). A total of 44.3% of patients with severe periodontitis also suffered from cardiovascular diseases, 19.1% respiratory diseases and 21.2% from diabetes mellitus. Among the controls, 30.9% had cardiovascular disease, 23.5% suffered from respiratory diseases and 6.7% had diabetes mellitus. Across both groups, hypertension was the most frequent diagnosis. There was a significant association between periodontitis and cardiovascular disease (odds ratio [OR] = 1.79, confidence interval [CI] 1.12-2.86), but not between respiratory diseases and periodontitis (OR= 0.88, CI 0.53-1.47). The risk of diabetes mellitus was greater among those patients with periodontitis (OR= 2.95, CI 1.45- 6.01). This study found that patients with periodontitis presented with more systemic diseases, such as cardiovascular disease and diabetes mellitus than control patients. However, no association was found between periodontitis and respiratory diseases. At the present time, the reasons for the associations or lack of association are unknown.

    Social media sites have become an established means of communication due to the exponential growth in number of users across the world and the encouragement of interaction between users through site features. The purpose of this study was to determine the extent to which Loma Linda University School of Dentistry students use social media accounts, the types of accounts they prefer, their interest in incorporating social media into courses and their perceptions of the usefulness of social media in private practice. In addition, we wanted to determine the degree of student interest in the integration of these social tools into their instruction. One thousand one hundred and sixty-two students from Loma Linda University School of Dentistry were invited by e-mail to complete a confidential 18 item multiple choice survey through Surveymonkey.com. The overall response rate was 30% (n = 351) from the pooled response periods; the first in 2011 and the second in 2013. Similar to other studies, Facebook was used by 91% of the School of Dentistry students, and less than half used Google+, Twitter and LinkedIn. Of the respondents, 68% of students reported communicating on social media daily and 80% saw value for practising dentists to operate accounts. Time and privacy concerns were the largest barriers to usage at 16% and 12% respectively. One third of respondents were in favour of the incorporation of social media in their courses.

    To help eliminate reported racial/ethnic and socioeconomic inequities in oral health care, listening to the perspectives of racial/ethnic minority older adults on their experiences with dental school clinics is needed. The aim of this study was to examine the experiences of African American, Puerto Rican, and Dominican older adults who attend senior centers in upper Manhattan, New York City, regarding the care received at dental school clinics. Focus groups were conducted from 2013 to 2015 with 194 racial/ethnic minority men and women aged 50 years and older living in upper Manhattan. All of the 24 focus group sessions were digitally audiorecorded and transcribed for analysis. Groups conducted in Spanish were transcribed first in Spanish and then translated into English. Analysis of the transcripts was conducted using thematic content analysis. Seven subthemes were manifest in the data related to these adults' positive experiences with dental school clinics: excellent outcomes and dentists, painless and safe treatment, affordable care, honest and reputable, benefits of student training, accepting and helpful, and recommended by family and friends. Negative experiences centered around four subthemes: multiple visits required for treatment, loss of interpersonal communication due to use of technology, inconvenient location, and perceived stigma with Medicaid. This study provided novel evidence of the largely positive experiences with dental schools of racial/ethnic minority senior center attendees. Interventions targeted at the organization and provider level, including organizational motivation, resources, staff attributes, climate, and teamwork plus payment programs and services, insurance and affordability, and provider- and system-level supports, may improve health care processes and patient experiences of care.

    It is unknown what disadvantages are faced by patients deciding for a prosthodontic treatment by inexperienced students. Commonly, the related extra effort and time are compensated by cost reduction of treatment fees. Thereby, the dental schools subsidize treatments to teach clinical prosthodontics. The aim of this study was to clarify the benefits to patients as well as the efforts of the dental school. Data collected from three courses in a dental school in Germany were patient gender, age, occupation, zip code, number of visits, scope of treatment including costs, financial discount, and remaining copayment. Travel costs were calculated based on zip code. Balance of travel costs and treatment discount was defined as financial benefit. The results showed that 185 patients (95 male) aged 32 to 82 years (median=58) were treated with fixed restorations (FR, n=110), telescopic dentures (TD, n=87), complete dentures (CD, n=17), or other (RD, n=3). The mean number of visits was 11 for FR, 12 for TD, and 9 for CD. Single distance to the clinic ranged from 0.6 to 65 miles (median=12). Total costs of prosthodontics were reduced by 19% on average. The mean financial benefit was 429 USD (median=298, min=-482, max=4025). The financial benefits were found to differ widely, including additional expenditures of patients. Participation, travel burden, and copayment did not depend on age, gender, or occupation. The financial benefit was relativized because students needed at least twice the sessions of a dentist. As a result, the financial efforts of dental schools are significant and compromise a cost-covering education.

    Full Text Available Objectives. To evaluate the influence of different whitening protocols on the efficacy of 35% hydrogen peroxide (HP tooth whitening and gel pH and concentration. Material and Methods. Eighty-four enamel/dentin discs from bovine incisors were used. The baseline color was measured with a spectrophotometer. Two sessions of in-office whitening with 35% HP were performed under different protocols: G1: 3 applications of HP (10 min each per session; G2: 1 application of 30 min per session; G3: 1 application of 40 min per session, with no gel replenishment within session for groups 2 and 3. HP titration and pH evaluation at baseline, after 10, 30, and 40 min were also performed. The final color was measured 24 h after the 1st and 2nd whitening sessions. Data were submitted to Repeated Measures ANOVA and Tukey’s test. Results. For color evaluation, no differences were observed among groups after two sessions. HP titration showed no drop on concentration after 10, 30, or 40 min. The pH was 5.54 at baseline and 5.41 after 40 min. Conclusion. Replenishment or extended application time of in-office whitening gel does not affect gel pH and concentration, a fact that supports the similar effectiveness of whitening observed among the tested protocols.

    Although dental education has traditionally been organized into basic sciences education (first and second years) and clinical education (third and fourth years), there has been growing interest in ways to better integrate the two to more effectively educate students and prepare them for practice. Since 2012, The University of Texas School of Dentistry at Houston (UTSD) has made it a priority to improve integration of basic and clinical sciences, with a focus to this point on integrating the basic sciences. The aim of this study was to determine the perspectives of basic and clinical science faculty members regarding basic and clinical sciences integration and the degree of integration currently occurring. In October 2016, all 227 faculty members (15 basic scientists and 212 clinicians) were invited to participate in an online survey. Of the 212 clinicians, 84 completed the clinician educator survey (response rate 40%). All 15 basic scientists completed the basic science educator survey (response rate 100%). The majority of basic and clinical respondents affirmed the value of integration (93.3%, 97.6%, respectively) and reported regular integration in their teaching (80%, 86.9%). There were no significant differences between basic scientists and clinicians on perceived importance (p=0.457) and comfort with integration (p=0.240), but the basic scientists were more likely to integrate (p=0.039) and collaborate (p=0.021) than the clinicians. There were no significant differences between generalist and specialist clinicians on importance (p=0.474) and degree (p=0.972) of integration in teaching and intent to collaborate (p=0.864), but the specialists reported feeling more comfortable presenting basic science information (p=0.033). Protected faculty time for collaborative efforts and a repository of integrated basic science and clinical examples for use in teaching and faculty development were recommended to improve integration. Although questions might be raised about

    This paper provides information about Peru's dental history and dental school system, including the curriculum and dental licensure. With the increase in the number of dental schools in Peru, the number of dentists is also increasing. Until 1965, Peru had only three dental schools; currently, there are 14. Four of these dental schools are public, and ten are private. A five- or six-year dental program leads to the B.D.S. degree. After successful completion of a thesis defense or competency examination, the D.D.S. degree is awarded. The D.D.S. is mandatory for practicing dentistry in Peru. Currently, there are approximately 14,000 active dentists, with a dentist-patient ratio of approximately 1:2,000.

    Every dental provider needs to be educated about medical emergencies to provide safe dental care. Simulation training is available with simulators such as advanced life support manikins and robot patients. However, the purchase and development costs of these simulators are high. We have developed a simulation training course on medical emergencies using an inexpensive software application. The purpose of this study was to evaluate the educational effectiveness of this course. Fifty-one dental providers participated in this study from December 2014 to March 2015. Medical simulation software was used to simulate a patient's vital signs. We evaluated participants' ability to diagnose and treat vasovagal syncope or anaphylaxis with an evaluation sheet and conducted a questionnaire before and after the scenario-based simulation training. The median evaluation sheet score for vasovagal syncope increased significantly from 7/9 before to 9/9 after simulation training. The median score for anaphylaxis also increased significantly from 8/12 to 12/12 (P simulation training. This simulation course improved participants' ability to diagnose and treat medical emergencies and improved their confidence. This course can be offered inexpensively using a software application. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Traumatic dental injuries to anterior teeth are a significant public health problem, not only because their prevalence is relatively high, but also because they have considerable impact on children's daily lives. Traumatic dental injuries (TDIs) cause physical and psychological discomfort, pain and other negative impacts, such as tendency to avoid laughing or smiling, which can affect social relationships. This study aimed to assess the prevalence of traumatic dental injuries to anterior teeth among 12-year-old school children in Kashmir, India. A cross-sectional study was conducted in private and government schools of India among 1600 schoolchildren aged 12 years. In addition to recording of the type of trauma (using Ellis and Davey classification of fractures, 1970), over jet, Angle's molar relation and lip competence were also recorded. The socioeconomic status and academic performance of the study subjects were registered. The data obtained were compiled systematically and then statistically analyzed. The statistical significance for the association between the traumatic injury and the variables was analyzed using the chi-square test. Logistic regression was used to identify potential risk predictors of TDIs. The overall prevalence of TDI to anterior teeth was found to be 9.3%. The TDI to anterior teeth in male was more than female, but the difference was statistically nonsignificant (P Academic performance was found to be significantly associated to TDI to anterior teeth, when analyzed in a multiple regression model. It was concluded that the prevalence of traumatic dental injuries was 9.3%. Traumatic dental injuries among children exhibit complex interaction between the victims' oral conditions and their behavior. Therefore, prevention should consider a number of characteristics such as oral predisposing factors, environmental determinants and human behavior. It is recommended that specific and proper public places for leisure and sports activities, with

    Ceramics are widely used materials for prosthesis, especially in dental fields. Despite multiple biomedical applications, little is known about ceramic surface modifications and the resulting cell behavior at its contact. The aim of this study is to evaluate the biological response of polished versus glazed surface treatments on lithium disilicate dental ceramic. We studied a lithium disilicate ceramic (IPS e.max(®) Press, Ivoclar Vivadent) with 3 different surface treatments: raw surface treatment, hand polished surface treatment, and glazed surface treatment (control samples are Thermanox(®), Nunc). In order to evaluate the possible modulation of cell response at the surface of ceramic, we compared polished versus glazed ceramics using an organotypic culture model of chicken epithelium. Our results show that the surface roughness is not modified as demonstrated by equivalent Ra measurements. On the contrary, the contact angle θ in water is very different between polished (84°) and glazed (33°) samples. The culture of epithelial tissues allowed a very precise assessment of histocompatibility of these interfaces and showed that polished samples increased cell adhesion and proliferation as compared to glazed samples. Lithium disilicate polished ceramic provided better adhesion and proliferation than lithium disilicate glazed ceramic. Taken together, our results demonstrate for the first time, how it is possible to use simple surface modifications to finely modulate the adhesion of tissues. Our results will help dental surgeons to choose the most appropriate surface treatment for a specific clinical application, in particular for the ceramic implant collar.

    Dental pulp stem cells (DPSCs) are a promising source of cells for numerous and varied regenerative medicine applications. Their natural function in the production of odontoblasts to create reparative dentin support applications in dentistry in the regeneration of tooth structures. However, they are also being investigated for the repair of tissues outside of the tooth. The ease of isolation of DPSCs from discarded or removed teeth offers a promising source of autologous cells, and their similarities with bone marrow stromal cells (BMSCs) suggest applications in musculoskeletal regenerative medicine. DPSCs are derived from the neural crest and, therefore, have a different developmental origin to BMSCs. These differences from BMSCs in origin and phenotype are being exploited in neurological and other applications. This review briefly highlights the source and functions of DPSCs and then focuses on in vivo applications across the breadth of regenerative medicine. © 2014 The Authors.

    Many obstacles need to be overcome if digital and electronic technologies are to be fully integrated in the operation of dental clinics in some countries. These obstacles may be physical, technical, or psychosocial barriers in the form of perceptions and attitudes related to software incompatibilities, patient privacy, and interference with the patient-practitioner relationship. The objectives of the study are to assess the perceptions of Indian dental students of one school toward the usefulness of digital technologies in improving dental practice; their willingness to use digital and electronic technologies; the perceived obstacles to the use of digital and electronic technologies in dental care setups; and their attitudes toward Internet privacy issues. The study population consisted of 186 final year undergraduate dental students from the A. B. Shetty Memorial institute of Dental Sciences, Rajiv Gandhi University of Health Sciences, Mangalore, India. Survey data were analyzed descriptively . Most students indicated that information technology enhances patient satisfaction, the quality of dental record, diagnosis, treatment planning, and doctor-doctor communication. Cost of equipment and need for technical training were regarded as major obstacles by substantial proportions of respondents. Most dental students at our school feel that the information technology will support their decision making in diagnoses and devising effective treatment plans, which in turn increase patient satisfaction and quality of care. Students also perceived that lack of technical knowledge and the high cost of implementation are major barriers to developing information technology in India.

    To discuss the development, pilot testing, and analysis of a 34-item semantic differential instrument for measuring medical school applicants' emotional intelligence (the EI instrument). The authors analyzed data from the admission interviews of 147 1997 applicants to a six-year BS/MD program that is composed of three consortium universities. They compared the applicants' scores on traditional admission criteria (e.g., GPA and traditional interview assessments) with their scores on the EI instrument (which comprised five dimensions of emotional intelligence), breaking the data out by consortium university (each of which has its own educational ethos) and gender. They assessed the EI instrument's reliability and validity for assessing noncognitive personal and interpersonal qualities of medical school applicants. The five dimensions of emotional intelligence (maturity, compassion, morality, sociability, and calm disposition) indicated fair to excellent internal consistency: reliability coefficients were .66 to .95. Emotional intelligence as measured by the instrument was related to both being female and matriculating at the consortium university that has an educational ethos that values the social sciences and humanities. Based on this pilot study, the 34-item EI instrument demonstrates the ability to measure attributes that indicate desirable personal and interpersonal skills in medical school applicants.

Materials and Methods: Participants were grouped according to their disability such as: Mild, moderate, severe mental retardation, hearing and speech defect and others (39 (including Down′s syndrome [20], autism [9], hyperactive [4], microcephaly [2], border line cases [4]. Examination was carried out at their schools, with participants seated in ordinary chairs and examined under natural light with mouth mirror and probe. Subjects were of different age groups ranging from 1 to 55 years. Statistical Analysis Used: Analysis of variance with post-hoc Games-Howell test was used for statistical analysis. Results: Mean dmft; DMFT scores were as follows: 2-6 years: 1.58 ± 1.9; 2.18 ± 2.94, 7-12 years: 1.1 ± 2.4; 1.9 ± 2.13, 13-30 years: 2.38 ± 2.5, 30+ years: 2.13 ± 3.2. Overall only 23% of subjects were caries free. "dmft" was statistically higher among moderate mentally retarded group while DMFT was statistically higher in mild and moderate mentally retarded groups. Conclusions: These findings emphasize the need of educating parents and caregivers of disabled individuals in preventive dental procedures, especially those of the mild and moderate mentally challenged group.

  8. Advances in Porous Biomaterials for Dental and Orthopaedic Applications

    2010-04-01

    Full Text Available The connective hard tissues bone and teeth are highly porous on a micrometer scale, but show high values of compression strength at a relatively low weight. The fabrication of porous materials has been actively researched and different processes have been developed that vary in preparation complexity and also in the type of porous material that they produce. Methodologies are available for determination of pore properties. The purpose of the paper is to give an overview of these methods, the role of porosity in natural porous materials and the effect of pore properties on the living tissues. The minimum pore size required to allow the ingrowth of mineralized tissue seems to be in the order of 50 µm: larger pore sizes seem to improve speed and depth of penetration of mineralized tissues into the biomaterial, but on the other hand impair the mechanical properties. The optimal pore size is therefore dependent on the application and the used material.

    Tooth decay is one of the greatest unmet treatment needs among children. Pain and suffering associated with untreated dental disease can lead to problems with eating, speaking, and learning. School-based dental sealant programs (SBSP) deliver a highly effective intervention to prevent tooth decay in children who might not receive regular dental care. SBSPs benefits exceed their costs when they target children at high risk for tooth decay. CDC used data from the National Health and Nutrition Examination Survey (NHANES) 2011-2014 to estimate current prevalences of sealant use and untreated tooth decay among low-income (≤185% of federal poverty level) and higher-income children aged 6-11 years and compared these estimates with 1999-2004 NHANES data. The mean number of decayed and filled first molars (DFFM) was estimated for children with and without sealants. Averted tooth decay resulting from increasing sealant use prevalence was also estimated. All reported differences are significant at pdental sealant use has increased; however, most children have not received sealants. Increasing sealant use prevalence could substantially reduce untreated decay, associated problems, and dental treatment costs.

    Dental caries is one of the most prevalent chronic diseases affecting children in Sub-Saharan Africa. Previous studies show a higher prevalence of dental caries in children from low socio-economic status backgrounds. The purpose of this study was to determine the prevalence of dental caries among 12 year old children in urban and rural areas of Zimbabwe and establish preliminary baseline data. A descriptive cross-sectional study was conducted among 12 year old children at primary schools in Harare and Bikita district. A Pre-tested questionnaire was administered to elicit information from the participants on tooth cleaning, dietary habits and dental experience. Dental caries status was assessed using the DMFT index following World Health Organization (WHO) guidelines. Our results showed a high prevalence of dental caries in both urban (59.5%) and rural (40.8%) children. The mean DMFT in urban and rural areas was 1.29 and 0.66, respectively. Furthermore, our data showed a general lack of knowledge on oral health issues by the participants. There is high prevalence of dental caries among 12 years old school children in both urban and rural areas of Zimbabwe. This calls for early preventive strategies and treatment services. We recommend incorporation of oral health education in the elementary school curricula.

  11. On the local applications of antibiotics and antibiotic-based agents in endodontics and dental traumatology.

    Antibiotics are a valuable adjunctive to the armamentarium available to health professionals for the management of bacterial infections. During endodontic treatment and when managing trauma to the teeth, antibiotics may be applied systemically (orally and/or parenterally) or locally (i.e. intra-dentally via irrigants and medicaments). Due to the potential risk of adverse effects following systemic application, and the ineffectiveness of systemic antibiotics in necrotic pulpless teeth and the periradicular tissues, the local application of antibiotics may be a more effective mode for delivery in endodontics. The aim of this article was to review the history, rationale and applications of antibiotic-containing irrigants and medicaments in endodontics and dental traumatology. The search was performed from 1981 to 2008 and was limited to English-language papers. The keywords searched on Medline were 'Antibiotics AND endodontics', 'Antibiotics AND root canal irrigation', 'Antibiotics AND intra-canal medicament', 'Antibiotics AND Dental trauma' and 'Antibiotics AND root resorption'. The reference section of each article was manually searched to find other suitable sources of information. It seems that local routes of antibiotic administration are a more effective mode than systemic applications. Various antibiotics have been tested in numerous studies and each has some advantages. Tetracyclines are a group of bacteriostatic antibiotics with antibacterial substantivity for up to 12 weeks. They are typically used in conjunction with corticosteroids and these combinations have anti-inflammatory, anti-bacterial and anti-resorptive properties, all of which help to reduce the periapical inflammatory reaction including clastic-cell mediated resorption. Tetracyclines have also been used as part of irrigating solutions but the substantivity is only for 4 weeks. Clindamycin and a combination of three antibiotics (metronidazole, ciprofloxacin and minocycline) have also been

    Objective: To evaluate the clinical application of helical CT 3D reconstruction technique in the dental orthopaedics. Methods: The helical CT was performed with 3.0 mm slice thickness and 1.0 pitch in 41 patients with dental orthopaedics. The 3D reconstructions, including maximum intensity projection (MIP), surface shaded display (SSD), and multiplanar reconstructions (MPR), were made for all the cases. Results: Thirty-seven of the 41 patients showed malalignment, tilt, rotation, overlap of the teeth and the different space between the longitudinal axes of the teeth. Twenty-five cases of them have shown 36 buried teeth in all. The axial images covered all the information. SSD demonstrated the external contours and entire morphologies of the teeth and the mandible with the relationship of the teeth alignment and the mandible. MIP clearly manifested the full view and the longitudinal alignment of the teeth. Among the 36 buried teeth, there were 29 palatally and 7 labially presented teeth, and they were morphologically delineated on MIP through various angles. Conclusion: The helical CT 3D reconstruction is a new technique to display the stereoscopic configuration of teeth. The combination of axial images and MIP, SSD, and MPR provides valuable anatomic and diagnostic information helpful for the surgeons to structure and determine the treatment protocol for the dental orthopaedics.

    To study the value and satisfaction of three-dimensional printing implant template and conventional implant template in multi-tooth dental implantation. Thirty cases (83 teeth) with missing teeth needing to be implanted were randomly divided into conventional implant template group (CIT group, 15 cases, 42 teeth) and 3D printing implant template group (TDPIT group, 15 cases, 41 teeth). Patients in CIT group were operated by using conventional implant template, while patients in TDPIT group were operated by using three-dimensional printing implant template. The differences of implant neck and tip deviation, implant angle deviation and angle satisfaction between the two groups were compared. The difference of probing depth and bone resorption of implant were compared 1 year after operation between the two groups. The difference of success rate and satisfaction of dental implantation were compared 1 year after operation between the two groups. SPSS19.0 software package was used for statistical analysis. The deviation direction of the neck and the tip in disto-mesial, bucco-palatal, vertical direction and angle of implants in disto-mesial and bucco-palatal direction in TDPIT group were significantly lower than in CIT group (P0.05). The difference of the cumulative success rate in dental implantation at 3 months and 6 months between the two groups were not significant (P>0.05), but the cumulative success rate of TDPIT group was significantly higher than CIT group at 9 months and 1 year (90.48% vs 100%,P=0.043). The patients' satisfaction rate of dental implantation in TDPIT group was significantly higher than in CIT group (86.67% vs 53.33%, P=0.046). Using three-dimensional printing implant template can obtain better accuracy of implant, higher implant success rate and better patients' satisfaction than using conventional implant template. It is suitable for clinical application.

    Full Text Available Background: A high prevalence of caries at ages ≥ 12 in Yogyakarta province (DMFT = 6.5, raises the question of the effectiveness of the school-based dental program (SBDP which, as a national oral health program in schools, is organized by community health centers (CHCs. Purpose: The aim of this study is to explore the possible constraints on work processes which might affect the performance of SBDPs in controlling caries. Methods: In-depth interviews was conducted in twelve CHCs, covering all five districts both in urban and rural areas. Subjects were 41 dentists and dental nurses working in these CHCs. The interviews were structured according to the following themes: resources and logistics; program planning; target achievement; monitoring and evaluation; and suggestions for possible improvements. The data were analyzed using content analysis. Results: The main constraints identified were limited resources and inflexible regulations for resource allocation in the CHC, and inadequate program planning and program evaluation. Inadequate participation of parents was also identified. Another constraint is thatpolicy at the district level orientates oral health towards curative intervention rather than prevention. Suggestions from interviewees include encouraging a policy for oral health, task delegation, a funding program using school health insurance, and a reorientation towards prevention. Conclusion: The weakness of management processes and the unsupported policy of the SBDP at the local level result in a lack of effectiveness.

    Full Text Available This study was conducted on 160 children, in the Bagalkot district of Karnataka state between August and October 2010, with the aim of finding out if there is a relation between dental fluorosis status and Intelligence Quotient (IQ. Children were categorized as, those suffering from dental fluorosis and those not suffering from dental fluorosis and for all children in both categories, Intelligence testing was done using the Raven′s Coloured Progressive Matrices. The following observations were made from the data gathered: The mean IQ score of children without dental fluorosis was significantly higher than those children who had dental fluorosis. The mean IQ scores did not vary with the severity of dental fluorosis as classified by Dean′s fluorosis index. Also it was noticed that the percentage of children with dental fluorosis was more in Extremely Low and Low IQ categories whereas the percentage of children without dental fluorosis was more in Average and High Average IQ categories. Previous studies had indicated toward decreased Intelligence in children exposed to high levels of fluoride and our study also confirmed such an effect.

    e-Assessment provides solutions to some problems encountered in dental students' evaluation. The aim of this study was to evaluate the experience of a limited-resources dental school with e-assessment provided through an open-source learning management system (LMS). Data about users' access and types of e-assessment activities at the Faculty of Dentistry, Alexandria University, Egypt, were obtained from the web-based LMS Moodle. A questionnaire developed to assess students' perceptions of the e-assessment was also sent to students registered in two courses (undergraduate and postgraduate) with the same instructor. The results showed that most e-courses at the school had one form of e-assessment (82%) and, of these, 16.7% had summative assessment activities. There were significant differences among departments in the number of e-courses with e-assessment. One-quarter of e-courses with e-assessment used Moodle quizzes. Of 285 students registered in the two courses that included the questionnaire, 170 responded (response rate=59.6%). The responding students positively perceived the impact of e-assessment on learning and its reliability and security, whereas technical issues and related stresses were negatively perceived. This study suggests that e-assessment can be used at minimal cost in dental schools with limited resources and large class sizes with the least demands on faculty members and teaching staff time. For these schools, an open-source LMS such as Moodle provides formative e-assessment not available otherwise and accommodates various question formats and varying levels of instructors' technical skills. These students seemed to have a positive impression of the e-assessment although technical problems and related stresses are issues that need to be addressed.

    Wilder-Smith, Petra; Otis, Linda; Zhang, Jun; Chen, Zhongping

    This chapter describes the applications of OCT for imaging in vivo dental and oral tissue. The oral cavity is a diverse environment that includes oral mucosa, gingival tissues, teeth and their supporting structures. Because OCT can image both hard and soft tissues of the oral cavity at high resolution, it offers the unique capacity to identity dental disease before destructive changes have progressed. OCT images depict clinically important anatomical features such as the location of soft tissue attachments, morphological changes in gingival tissue, tooth decay, enamel thickness and decay, as well as the structural integrity of dental restorations. OCT imaging allows for earlier intervention than is possible with current diagnostic modalities.

    BACKGROUND - Globally, human resources for health are being optimized to address the increasing health burden and concomitant increased demands on health professionals. These demands are even more exacting in Sub-SaharanAfrica considering the shortage of health care workers, especially physicians. The noteworthy efforts at deploying task-shifting to address this situation not-withstanding, the situation also signals the need to re-define the objectives of medical instruction to ensure effective and contemporary medical practice in a mostly physician-led health workforce across the sub-continent. In this regard, medical and dental graduates must be educated to perform certain minimum essential professional duties competently. Essential Professional Duties are locally relevant professional activities of international standard that represent identifiable outcomes against which the effectiveness of physicians in a specific community can be measured to ensure social accountability. PROCEDURE AND PRODUCT - The Association of Medical Schools of Africa has developed the 'Essential Professional Duties for sub-Saharan medical and dental graduates' to ensure these physicians provide safe and effective contemporary medical/dental practice on the sub-continent. The duties have been grouped into those required for basic patient care, basic administrative skills, basic emergency care, communication, inter-professional relationships, self-directed learning and social responsibilities. Their relevance and suitability have been evaluated prior to their adoption by the Association. CONCLUSION; These Essential Physician Duties have been developed to serve as targets for health professionals training instruments and thus give direction to health system strategies. It is hoped that they will be adopted by medical and dental schools across sub-,. Saharan Africa.

    The purpose of this study was to survey members of The American College of Prosthodontists (ACP) to evaluate current materials and methods for final impressions for complete denture prosthodontics in the United States. In addition, those methods were compared with methods and materials taught in U.S. dental schools via a second survey sent to the chairpersons of prosthodontic/restorative departments. An anonymous questionnaire was mailed to all 1762 active ACP members in the United States in 2003. A slightly modified questionnaire was also distributed to chairpersons of prosthodontic/restorative departments in the 54 U.S. dental schools. Data analysis was performed via frequency distribution and chi-square statistics. Nine hundred and forty-five questionnaires were returned by members of the ACP (54% return rate) and 42 questionnaires were returned by the U.S. dental schools (78% return rate). The majority of the reporting prosthodontists (88%) and dental schools (98%) use a border-molded custom tray for final impressions for complete denture prosthodontics. The most popular material for border molding was plastic modeling compound (67% of reporting ACP members, and 95% of the responding dental schools). Variability of the materials used for final impressions was observed, with the most popular materials being polyvinylsiloxane for the ACP members (36%) and polysulfide for the dental schools (64%). Statistically significant differences were found in the materials used for border molding by prosthodontists based on the time elapsed since completion of prosthodontic training. No differences were found in the materials used for impression of edentulous arches based on years of experience. Geographic location did not influence the materials and methods used by prosthodontists for complete denture final impressions. There was variability of the materials and techniques used for final impressions by ACP members and dental schools; however, overall there was an agreement

    Although direct drinking water (DDW) systems that utilize a reverse-osmosis technique are thought to be harmful to children's development by reducing their daily mineral intake, few population data are available regarding this topic. We conducted an eco-epidemiological study to investigate the influence of low-mineral DDW on the development of schoolchildren. We collected developmental parameters of 13,723 girls and 16,161 boys before and after the introduction of DDW systems in 25 schools and measured the mineral levels in the DDW of each school. The DDW in 22 schools had lower-than-recommended levels of magnesium and calcium (magnesium, 10 mg/L and calcium, 20 mg/L, WHO). We found that children exposed to low-mineral DDW exhibited reduced height and diminished height increases as well as higher prevalences and incidences of hypoevolutism and dental caries (p water.

    Full Text Available BACKGROUND AND AIM:Estimation of need and demand for orthodontic treatment is important for both healthprofessionals and health policymakers. Need assessment is traditionally done using experts’ opinions;however, patient-centered evaluation can provide a bigger picture ofpatient’s esthetic and psychological needs. The willingness to pay(WTP technique is a potentially valid tool for assessing the patient views on their needs and for market research inhealthcare.The aim of this study was to evaluate the need anddemand for orthodontic treatment with a patient-centeredapproach using economic analysis.METHODS:A cross-sectional study was designed. Two hundred people attending Shiraz Dental School Clinic wereinterviewed. Their views on the importance and costs of orthodontic treatments and the maximum amountthat theywould pay for such treatments were obtained along with their demographic and socioeconomic factors. Their WTP wasused to elicit values for orthodontic treatment using contingent valuation method (CVM and econometric techniques.RESULTS:The response rate was 95%. Although 53.5% of respondents felt they needed orthodontic treatment, only33.7% had expressed their need, and just 17.5% hadactually gone for such treatment. The main reason for not takingthe treatment was its cost (56.5%. More than 60% of respondents viewed orthodontics as only a luxurytreatment and70% considered beauty and elegant smile as the most, or one of the most, benefit(s of orthodontic treatments. WTPresults showed that orthodontic services have highdemand elasticity. Assuming fixed monthly income of8 millionRials, 61% of subjects were ready to pay 20 millionRials for a course of orthodontic treatment.CONCLUSIONS:The result showed that esthetics and high cost of treatment were respectively the most intriguing andthemain inhibiting factors for getting orthodontic treatment. Economic evaluation showed a high elastic estimation fororthodontic treatment.

    This study aimed to develop a copper-aluminium-nickel alloy which has properties comparable to that of dental alloys used for dental post and core applications with the reasonable cost. Sixteen groups of experimental copper alloys with variants of 3, 6, 9, 12 wt% Al and 0, 2, 4, 6 wt% Ni were prepared and casted. Their properties were tested and evaluated. The data of thermal, physical, and mechanical properties were analyzed using the two-way ANOVA and Tukey's test (α=0.05). The alloy toxicity was evaluated according to the ISO standard. The solidus and liquidus points of experimental alloys ranged from 1023℃ to 1113℃ and increased as the nickel content increased. The highest ultimate tensile strength (595.9 ± 14.2 MPa) was shown in the Cu-12Al-4Ni alloy. The tensile strength was increased as the both elements increased. Alloys with 3-6 wt% Al exhibited a small amount of 0.2% proof strength. Accordingly, the Cu-9Al-2Ni and Cu-9Al-4Ni alloys not only demonstrated an appropriate modulus of elasticity (113.9 ± 8.0 and 122.8 ± 11.3 GPa, respectively), but also had a value of 0.2% proof strength (190.8 ± 4.8 and 198.2 ± 3.4 MPa, respectively), which complied with the ISO standard requirement (>180 MPa). Alloys with the highest contents of nickel (6 wt% Ni) revealed a widespread decolourisation zone (5.0-5.9 mm), which correspondingly produced the largest cell response, equating positive control. The copper alloys fused with 9 wt% Al and 2-4 wt% Ni can be considered for a potential use as dental post and core applications.

    Good mechanical properties, biocompatibility and corrosion resistance make titanium an excellent material for biomedical applications. However, when better mechanical properties than those offered by commercially pure titanium (CPTi) are needed, Ti-6Al-4V is sometimes a good alternative. Some new titanium alloys, developed as industrial structural materials, aim at an intermediate range of strength between that of CP Ti and Ti-6Al-4V. Two of these alloys are Super-TIX800TM (Ti-1% Fe-0.35% O-0.01% N) and Super-TIX800NTM (Ti-1% Fe-0.3% O-0.04% N) (both produced by Nippon Steel Corp., Japan). Besides being stronger than CP Ti, the cost of manufacturing these alloys is reportedly lower than for Ti-6Al-4V since they do not contain any expensive elements. In addition, they are not composed of elements such as aluminum or vanadium, which have caused biocompatibility concerns in medical and dental appliances. To evaluate these alloys as candidates for dental use, it is helpful to compare them to CP Ti (ASTM Grade 2) and Ti-6Al-4V (ASTM Grade 5), which have already been employed in dentistry. We evaluated the tensile properties, mold filling capacity, corrosion characteristics and grindability of these industrial alloys prepared by investment casting. Compared to the strengths of cast CPTi, the yield strength and tensile strength of these cast alloys were more than 20% and approximately 30% higher, respectively. On the other hand, both of these properties were 30% lower than for Ti-6Al-4V. Better grindability and wear resistance were additional benefits of these new alloys for dental applications

    To synthesize and characterize machinable, bioactive glass-ceramics (GCs) suitable for dental implant applications. A glass in the SiO2-Al2O3-CaO-CaF2-K2O-B2O3-La2O3 system was synthesized by wet chemical methods, followed by calcination, melting and quenching. Crystallization kinetics were determined by differential thermal analysis (DTA). GC discs were produced by cold pressing of the glass powder and sintered using schedules determined by DTA. The crystalline phases and microstructure of GC samples were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM), respectively. Dynamic Young's modulus (E), true hardness (Ho), fracture toughness (KIC) and brittleness index (BI) were evaluated. Bioactivity was studied by examining the formation of hydroxyapatite (HA) on the GC surfaces after soaking in simulated body fluid (SBF). Attachment and proliferation of MC3T3-E1 osteoblastic cells were assessed in vitro. Miserite [KCa5(Si2O7)(Si6O15)(OH)F] was the main crystalline phase of the GC with additional secondary phases. Microstructural studies revealed interlocking lath-like crystalline morphology. E, Ho, and KIC values for the GCs were 96±3 GPa, 5.27±0.26 GPa and 4.77±0.27 MPa m(0.5), respectively. The BI was found to be 1.11±0.05 μm(-0.5), indicating outstanding machinability. An HA surface layer was formed on the GC surfaces when soaked in SBF, indicating potential bioactivity. MC3T3-E1 cells exhibited attachment, spreading and proliferation on GC surfaces, demonstrating excellent biocompatibility. We present a novel approach for the synthesis of miserite GC with the physical and biological properties required for non-metallic dental implant applications.

    To assess the knowledge and perceptions of Malaysian government dentists regarding the shortened dental arch (SDA) concept and its application in clinical practice. The SDA concept refers to a specific type of dentition with intact anterior teeth and a reduction in posterior occlusal pairs. Dentists' knowledge and perceptions of the SDA concept can influence its application in clinical practice. A self-administered questionnaire on the SDA concept was distributed to 326 government dentists in the states of Selangor and Kuala Lumpur, Malaysia. The data were analysed using SPSS version 22 software. The response rate was 84.0%. The majority of respondents had good knowledge on five of six knowledge items and good attitudes towards 10 of 17 perception items. However, only one-fifth (20.4%) reported having applied the SDA concept in the clinic. A larger number of participants who graduated locally than who graduated abroad perceived that patients 5 years of work experience perceived that the SDA concept enables simpler treatment planning (P concept, it is not widely applied in the clinic. Concerted efforts in SDA training of dentists are needed to help to shorten denture waiting lists and reduce costs. © 2017 FDI World Dental Federation.

    Full Text Available Introduction and objective: Tooth caries is the most prevalent infectious disease in children. The purpose of this study was to assess carries experience indexes and related factors among 7-12 year-old school children in Yasuj, Iran, in 2014. Materials and methods: In the present Cross-sectional and analytical study, using a two-stage random sampling, 460 students from primary schools of Yasuj city and surrounding villages were selected. The children were clinically examined at their school by a professional calibrated dentistry team. Their demographic and socioeconomic status, mouth health behaviors and teeth carries status and consumed nutritional materials were gathered by a questioner and a dental chart. The data were analyzed using inferential statistical methods. The SPSS software version 22 was used to extract the outputs and &alpha=0.05 was considered as the significant level. Results: The dental caries prevalence of deciduous, permanent and total of  two type of dents were  75.2, 41.1 and  89.8 percent, respectively and the dmft, DMFT and dmft+DMFT indexes were 3.57, 0.87, and 4.44, respectively.. The caries prevalence of permanent teeth and DMFT in girls were significantly higher than boys (p=0.046, but the caries prevalence in total of dents in boys was significantly higher than girls ( p=0.32. Furthermore, the dental caries prevalence in permanent teeth and DMFT in children resident in rural areas were significantly higher than those in urban areas (p0.1.  Conclusions: Prevalence and severity score of dental caries among 7 - 12 year-old Yasuj students were higher than the WHO standards. The tooth caries experiences were more prevalent in boys and in children resident in rural areas, increased with age and decreased with BMI and less prevalent in children with higher family socioeconomic status.

    Full Text Available An observational study was conducted to determine dietary fluoride intake, diet, and prevalence of dental and skeletal fluorosis of school age children in three fluorosis endemic districts of the Ethiopian Rift Valley having similar concentrations of fluoride (F in drinking water (~5 mg F/L. The duplicate plate method was used to collect foods consumed by children over 24 h from 20 households in each community (n = 60 and the foods, along with water and beverages, were analyzed for fluoride (F content. Prevalence of dental and skeletal fluorosis was determined using presence of clinical symptoms in children (n = 220. Daily dietary fluoride intake was at or above tolerable upper intake level (UL of 10 mg F/day and the dietary sources (water, prepared food and beverages all contributed to the daily fluoride burden. Urinary fluoride in children from Fentale and Adamitulu was almost twice (>5 mg/L the concentration found in urine from children from Alaba, where rain water harvesting was most common. Severe and moderate dental fluorosis was found in Alaba and Adamitulu, the highest severity and prevalence being in the latter district where staple foods were lowest in calcium. Children in all three areas showed evidence of both skeletal and non-skeletal fluorosis. Our data support the hypothesis that intake of calcium rich foods in addition to using rain water for household consumption and preparation of food, may help in reducing risk of fluorosis in Ethiopia, but prospective studies are needed.

    The purpose of this study was to determine the prevalence of tooth decay and its correlation with dental care habits in northwestern Ivory Coast. Study was carried out in primary schools in the city of Odienne in January 1999. The study cohort comprised 500 students of both genders ranging in age from 4 to 15 years. The prevalence of tooth decay was 77.2% and the mean CAO index was 2.43. Dental care involved use of a chewing stick in 49% and a tooth brush in 50.8%. Only 5.6% of children cleaned their teeth three-times a day on a regular basis. Statistical analysis of study data demonstrated a correlation between the frequency of tooth cleaning and incidence of tooth decay. The incidence of tooth decay was 60.7% in students that cleaned their teeth three times a day versus 78.2% in students who cleaned their teeth less regularly. An educational campaign has been undertaken to inform students of the importance of oral hygiene in maintaining healthy teeth. A dental examination program would be useful to provide routine check-ups. A group study will be needed to monitor oral hygiene in students and evaluate the impact of these measures on tooth decay.

    Dental caries is highly prevalent and a significant public health problem among children throughout the world. Epidemiological data regarding prevalence of dental caries amongst Pakistani pre-school children is very limited. The objective of this study is to determine the frequency of dental caries among pre-school children of Saddar Town, Karachi, Pakistan and the factors related to caries. A cross-sectional study of 1000 preschool children was conducted in Saddar town, Karachi. Two-stage cluster sampling was used to select the sample. At first stage, eight clusters were selected randomly from total 11 clusters. In second stage, from the eight selected clusters, preschools were identified and children between 3- to 6-years age group were assessed for dental caries. Caries prevalence was 51% with a mean dmft score being 2.08 (±2.97) of which decayed teeth constituted 1.95. The mean dmft of males was 2.3 (±3.08) and of females was 1.90 (±2.90). The mean dmft of 3, 4, 5 and 6-year olds was 1.65, 2.11, 2.16 and 3.11 respectively. A significant association was found between dental caries and following variables: age group of 4-years (p-value dental plaque (p-value dental caries coupled with a high prevalence of unmet dental treatment needs. Association between caries experience and age of child, consumption of non-sweetened milk, dental plaque and poor oral hygiene had been established.

    Adolescents and emerging adults can provide dentists with many challenges. Little information is available on their perceptions of dental costs once they turn 18 and dentistry is no longer State-funded. The aim of this study was to explore the use of dental care by Southland students in years 12 and 13, their perceptions of the cost of four common dental procedures, self-related oral health and dental self-care habits, time off school related to dental problems, and knowledge and views regarding fluoride. After ethical approval, a 26-question survey was conducted of all Southland students in years 12 and 13. Data were statistically analysed in SPSS version 20 with the alpha value set at 0.05. The participation rate was 49.6%. Regular attendance for examinations was reported by 77.5% with non-attendance mainly related to attitudes around lack of importance or necessity. Reported dental attendance varied according to gender, ethnicity and decile rating of school attended. Although some were accurate in their estimations of dental costs, the standard deviation for all procedures was large. The majority thought that costs put people off going to the dentist. While 74.8% brushed their teeth at least twice daily, only 26.6% flossed regularly. Knowledge regarding fluoride was lacking. It may be advantageous to include education regarding costs of dental care with patients of this age. This may motivate them to improve their self-care and ensure that their oral health is of a high standard before their dental needs are no longer State-funded.

    To identify computer facilities available in 3 dental schools where 3 different approaches to the use of technology-based learning material have been adopted and assess dental students' perception of their own computer skills and their attitudes towards information technology. Multicentre cross sectional by questionnaire. All 181 dental students in their final year of study (1997-8). The overall participation rate was 80%. There were no differences between schools in the students' self assessment of their IT skills but only 1/3 regarded themselves as competent in basic skills and nearly 50% of students in all 3 schools felt that insufficient IT training had been provided to enable them to follow their course without difficulty. There were significant differences between schools in most of the other areas examined which reflect the different ways in which IT can be used to support the dental course. 1. Students value IT as an educational tool. 2. Their awareness of the relevance of a knowledge of information technology for their future careers remains generally low. 3. There is a need to provide effective instruction in IT skills for those dental students who do not acquire these during secondary education.

    The purpose of this study was to investigate the effects on the enamel properties and effectiveness of bleaching using 35% hydrogen peroxide (HP) when applying toothpastes with different active agents prior to dental bleaching. Seventy enamel blocks (4 × 4 × 2 mm) were submitted to in vitro treatment protocols in a tooth-brushing machine (n=10): with distilled water and exposure to placebo gel (negative control [NC]) or HP bleaching (positive control [PC]); and brushing with differing toothpastes prior to HP bleaching, including potassium nitrate toothpaste (PN) containing NaF, conventional sodium monofluorophosphate toothpaste (FT), arginine-based toothpastes (PA and SAN), or a toothpaste containing bioactive glass (NM). Color changes were determined using the CIE L*a*b* system (ΔE, ΔL, Δa, and Δb), and a roughness (Ra) analysis was performed before and after treatments. Surface microhardness (SMH) and cross-sectional microhardness (CSMH) were analyzed after treatment. Data were analyzed with repeated measures ANOVA for Ra, one-way ANOVA (SMH, ΔE, ΔL, Δa, and Δb), split-plot ANOVA (CSMH), and Tukey post hoc test (α PA = SAN > all other groups) or decreased HP effects (CSMH). Ra increased in all bleached groups, with the exception of NM, which did not differ from the NC. The variation in the color variables (ΔL, Δa, and Δb) explained 21% of the variation in the physical surface variables (Ra and SMH). The application of toothpaste prior to dental bleaching did not interfere with the effectiveness of treatment. The bioactive glass based toothpaste protected the enamel against the deleterious effects of dental bleaching.

    Objective Cone beam computed tomography (CBCT) is an important image technique for oral surgery (dentoalveolar surgery and dental implantology) and maxillofacial applications. This technique requires compact sized scanners with a relatively low radiation dosage, which makes them suitable for imaging of the craniofacial region. This article aims to present the concept and the preliminary findings obtained with the prototype of a new CBCT scanner with dedicated 3D software, specifically designed for dental imaging. Methods The prototype implements an X-ray tube with a nominal focal spot of 0.5 mm operating at 70-100 kVp and 1-4 mA. The detector is a 6 in. image intensifier coupled with a digital CCD camera. Dosimetry was performed on a RANDO anthropomorphic phantom using Beryllium Oxide thermo-luminescent dosimeters positioned in the phantom in the following site: eyes, thyroid, skin (lips, cheeks, back of the neck), brain, mandible, maxilla and parotid glands. Doses were measured using four configurations, changing the field-of-view (4'' and 6'') and acquisition time (10 and 20 s) of the CBCT. Acquisitions were performed with different parameters regarding the x-ray tube, pixel size and acquisition geometries to evaluate image quality in relation to modulation transfer function (MTF), noise and geometric accuracy. Results The prototype was able to acquire a complete maxillofacial scan in 10-15 s. The CT reconstruction algorithm delivered images that were judged to have high quality, allowing for precise volume rendering. The radiation dose was determined to be 1-1.5 times that of the dose applied during conventional dental panoramic studies. Conclusion Preliminary studies using the CBCT prototype indicate that this device provides images with acceptable diagnostic content at a relatively low radiation dosage, if compared to systems currently available on the market.

    This study aimed to evaluate and correlate the efficacy and cytotoxicity of a 35 % hydrogen peroxide (HP) bleaching gel after different application times on dental enamel. Enamel/dentin disks in artificial pulp chambers were placed in wells containing culture medium. The following groups were formed: G1, control (no bleaching); G2 and G3, three or one 15-min bleaching applications, respectively; and G4 and G5, three or one 5-min bleaching applications, respectively. Extracts (culture medium with bleaching gel components) were applied for 60 min on cultured odontoblast-like MDPC-23 cells. Cell metabolism (methyl tetrazolium assay) (Kruskal-Wallis/Mann-Whitney; α = 5 %) and cell morphology (scanning electron microscopy) were analyzed immediately after the bleaching procedures and the trans-enamel and trans-dentinal HP diffusion quantified (one-way analysis of variance/Tukey's test; α = 5 %). The alkaline phosphatase (ALP) activity was evaluated 24 h after the contact time of the extracts with the cells (Kruskal-Wallis/Mann-Whitney; α = 5 %). Tooth color was analyzed before and 24 h after bleaching using a spectrophotometer according to the Commission Internationale de l'Eclairage L*a*b* system (Kruskal-Wallis/Mann-Whitney; α = 0.05). Significant difference (p 0.05). The lowest amount of HP diffusion was observed in G5 (p 0.05). HP diffusion through dental tissues and its cytotoxic effects were proportional to the contact time of the bleaching gel with enamel. However, shorter bleaching times reduced bleaching efficacy. Shortening the in-office tooth bleaching time could be an alternative to minimize the cytotoxic effects of this clinical procedure to pulp tissue. However, the reduced time of bleaching agent application on enamel may not provide adequate esthetic outcome.

    The main properties (mechanical, thermal and chemical) and clinical application for dental restoration are demonstrated for three types of glass-ceramics and sintered polycrystalline ceramic produced by Ivoclar Vivadent AG. Two types of glass-ceramics are derived from the leucite-type and the lithium disilicate-type. The third type of dental materials represents a ZrO2 ceramic. CAD/CAM technology is a procedure to manufacture dental ceramic restoration. Leucite-type glass-ceramics demonstrate high translucency, preferable optical/mechanical properties and an application as dental inlays, onlays and crowns. Based on an improvement of the mechanical parameters, specially the strength and toughness, the lithium disilicate glass-ceramics are used as crowns; applying a procedure to machine an intermediate product and producing the final glass-ceramic by an additional heat treatment. Small dental bridges of lithium disilicate glass-ceramic were fabricated using a molding technology. ZrO2 ceramics show high toughness and strength and were veneered with fluoroapatite glass-ceramic. Machining is possible with a porous intermediate product.

    Interest is increasing in the development of new methodologies for accidental dose assessment, exploiting the luminescence and dosimetric properties of objects and materials which can be usually found directly on exposed subjects and/or in the contaminated area. In this work, several types of ceramics employed for dental prosthetics restoration, including both innovative materials used as sub-frames for the construction of the inner part of dental crowns (core), and conventional porcelains used for the fabrication of the external layer (veneer), were investigated with regard to their thermally and optically stimulated luminescence (TSL and OSL respectively) properties, in view of their potential application in accidental dosimetry. The sensitivity to ionizing radiation proved to strongly depend on the type and brand of ceramic, with minimum detectable dose ranging from few mGy up to several tens of mGy. A linear dose-response was observed for most of the samples. However, the luminescence signals were characterised by a significant fading, which has to be taken into account for a reliable accidental dose assessment after a radiation exposure event.

    Full Text Available The potential application of stem cell biology in human dentistry is a new and emerging field of research. The objective of the current review was to study the efficiency of mesenchymal stem cells (MSCs in sinus lift augmentation (SLA. A literature review was performed in PubMed Central using MeSH keywords such as sinus lift, MSCs, dental implants, and augmentation. The searches involved full-text papers written in English, published in the past 10 years (2007–2017. The review included in vitro and in vivo studies on the use of MSCs in SLA. Electronic searching provided 45 titles, and among them, 8 papers were chosen as suitable based on the inclusion requirements of this review. The reviewed studies have revealed the potential of MSCs in SLA. According to these papers, stem cell therapy combined with different biomaterials may considerably improve bone regeneration in previous steps of dental implantation and may veritably lead to efficient clinical usages in the recent future. However, the identification of an ideal source of stem cells as well as long-term studies is vital to assess the success rate of this technology. Further clinical trials are also needed to approve the potential of MSCs in SLA.

    To determine the dental caries experience and treatment needs among 5-year-olds in Albania. This cross sectional study was conducted in 2015 by using a cluster sampling technique. The dmft was used to assess dental caries experience and caries prevalence as percentages of children with dmf⟩0. Caries treatment needs were assessed with dt/dmft x 100, missing teeth with mt/dmft x 100 and ft /dmft x 100 as the Care Index. 2,039 five-year-olds, from 17 districts of Albania were selected . Children's residency was divided into 3 main regions (South, West, Central and North). WHO 2013 diagnostic criteria were used and dental caries was recorded at cavity level d3. The mean age was 5.4 (SD 0.5) years. The caries prevalence (dmf⟩0) was 84.1%. The prevalence of children without cavitated lesions (d=0) was 20.1%. The mean dmft index was 4.41 (SD 3.83). The caries treatment needs were 84% (SD 26%). The Albanian 5-year-olds assessed in this survey had a high dental caries experience and untreated cavities in the primary dentition. The national health authorities should introduce preventive programs and improved dental care access for this age group. Copyright© 2017 Dennis Barber Ltd

This article examines how the world of social media has changed dental education. Its goal is to outline the complex issues that social media use presents for academic dental institutions and to examine these issues from personal, professional, and legal perspectives. After providing an update on social media, the article considers the advantages and risks associated with the use of social media at the interpersonal, professional, and institutional levels. Policies and legal issues of which academic dental institutions need to be aware from a compliance perspective are examined, along with considerations and resources needed to develop effective social media policies. The challenge facing dental educators is how to capitalize on the benefits that social media offer, while minimizing risks and complying with the various forms of legal constraint.

    The aim of this study was to know the distribution of dental developmental alterations in the population requesting stomatological attention at the Admission and Diagnosis Clinic of our institution in Mexico City. We reviewed the archives and selected those files with developmental dental alterations. Analyzed data were diagnoses, age, gender, location and number of involved teeth. Of the 3.522 patients reviewed, 179 (5.1%) harbored 394 developmental dental alterations. Of them, 45.2% were males and 54.8% were females with a mean age of 16.7 years. The most common were supernumeraries, dental agenesia and dilaceration. Adults were 30.7% of the patients with dental developmental alterations. In them, the most common lesions were agenesia and supernumeraries. Mesiodens was the most frequently found supernumerary teeth (14.7%). Our finding that 30.7% of the affected patients were adults is an undescribed and unusually high proportion of patients that have implications on planning and prognosis of their stomatological treatment.

    This study was conducted to assess the level of participation of dental undergraduate students in extracurricular activities (ECAs) and the factors affecting this participation. The study included dental students enrolled in undergraduate programs at the Faculty of Dentistry, Alexandria University, Egypt, and the College of Dentistry, University of Dammam, Saudi Arabia. A questionnaire was developed to collect background information about students, their participation in ECAs, and time allocated for these activities. Students were asked about their perceptions of the relationship between ECAs and academic studies, and their reasons for participating in and satisfaction with ECAs. The study included 199 students from Alexandria and 146 students from Dammam, with response rates of 99.5% and 73%, respectively. The percentages of those reporting ECA participation were 27.1% and 43.8%, respectively, mostly in community service, sports, and social activities. About 60% of students did not think that ECAs affected their studies, although the perceived difficulty of balancing ECAs and academics was associated with lower odds of participation (odds ratio = 0.51). Most students participated in ECAs to socialize and make friends, and the majority was dissatisfied with school-organized ECAs (52% and 59%, respectively). Gender and/or perceived relation between ECAs and academic studies affected actual participation in ECAs in one school but not the other. ECA participation among these students was low. Gender and perception of ECAs in relation to academic studies affected ECA participation differently in the two schools. Better planning and management of ECAs that incorporate students' preferences and reasons for participation is needed. Gender issues and the relationship between ECAs and academic performance should be addressed in relation to school and social characteristics.

    Full Text Available Caries remains prevalent throughout modern society and is the main disease in the field of dentistry. Although studies of this disease have used diverse methodology, recently, X-ray microtomography has gained popularity as a non-destructive, 3-dimensional (3D analytical technique, and has several advantages over the conventional methods. According to X-ray source, it is classified as monochromatic or polychromatic with the latter being more widely used due to the high cost of the monochromatic source despite some advantages. The determination of mineral density profiles based on changes in X-ray attenuation is the principle of this method and calibration and image processing procedures are needed for the better image and reproducible measurements. Using this tool, 3D reconstruction is also possible and it enables to visualize the internal structures of dental caries. With the advances in the computer technology, more diverse applications are being studied, such automated caries assessment algorithms.

    Full Text Available There is an increased interest in the use of polyether ether ketone (PEEK for orthopedic and dental implant applications due to its elastic modulus close to that of bone, biocompatibility, and its radiolucent properties. However, PEEK is still categorized as bioinert due to its low integration with surrounding tissues. Many studies have reported on methods to increase the bioactivity of PEEK, but there is still one-preparation method for preparing bioactive PEEK implant where the produced implant with desirable mechanical and bioactivity properties is required. The aim of this review is to present the progress of the preparation methods for improvement of the bioactivity of PEEK and to discuss the strengths and weaknesses of the existing methods.

    School in Plaza de la Revolución municipality from January to December 2006, and to identify in the studied group the frequency of children according to the number of incipient lesion, as well as the frequency of incipient lesions per tooth localization in the arcade and per dental surface. METHODS: an observational descriptive cross-sectional study was undertaken. The universe consisted of all the children aged 6-11 that fulfilled the inclusion criteria for a total of 236, who were examined in the open-air and with natural light by using the soft visual-tactile method. The teeth were cleaned with cotton and were dried with air to detect the presence of incipient carious lesions, which were indicated in a dentigram model in the place corresponding to the surface affected. RESULTS: it was found that 22.5 % of the school children examined presented these lesions. Of them, 60.1 % were females, 19.5 % of the total of children presented a lesion and just 3 % had 2 incipient lesions of dental caries; 79.2 % of them were observed in the posterior tooth. The smooth surfaces were the most affected with 45.3 %. CONCLUSIONS: Approximately the fourth part of the studied children presented incipient carious lesions. Females were the most affected. Of all the children with incipient lesions, the highest figure corresponded to those having a lesion. The posterior teeth were the most affected by incipient lesions. The smooth surfaces showed more incipient lesions than the occlusal and proximal

    The goal of this article is to describe the broad curricular constructs surrounding teaching and learning about social media in dental education. This analysis takes into account timing, development, and assessment of the knowledge, skills, attitudes, and behaviors needed to effectively use social media tools as a contemporary dentist. Three developmental stages in a student's path to becoming a competent professional are described: from undergraduate to dental student, from the classroom and preclinical simulation laboratory to the clinical setting, and from dental student to licensed practitioner. Considerations for developing the dental curriculum and suggestions for effective instruction at each stage are offered. In all three stages in the future dentist's evolution, faculty members need to educate students about appropriate professional uses of social media. Faculty members should provide instruction on the beneficial aspects of this communication medium and help students recognize the potential pitfalls associated with its use. The authors provide guidelines for customizing instruction to complement each stage of development, recognizing that careful timing is not only important for optimal learning but can prevent inappropriate use of social media as students are introduced to novel situations.

    Social networking applications have become an established means of communication; applications that did not exist ten years ago are now used daily. Social media can be used for a myriad of reasons including instructional tools to supplement learning. This project was designed to assess the usage of social media applications by dental school faculty members and identify the types of accounts they prefer. Four hundred forty-three full-time dental and dental hygiene faculty members from five U.S. dental schools were invited to complete a twelve-item online survey regarding their social media usage. The response rate was 50 percent (n=221). Of the respondents, nearly half were dentists, and 62 percent were ≥51 years of age. Facebook was the most popular social network, reportedly used by 111 respondents. The most often reported frequency of use was weekly (20.4 percent, n=221); users indicated utilizing a network primarily for personal rather than professional purposes. However, 37 percent of the respondents reported not using any social media. The most frequently cited barriers to the use of social media were time (48 percent) and privacy concerns (48 percent). Although few would dispute the influence social media has on today's students, the suitability and appropriateness of social media technology and its integration into dental curricula require further evaluation.

    The zero-inflated negative binomial regression model (ZINB) is often employed in diverse fields such as dentistry, health care utilization, highway safety, and medicine to examine relationships between exposures of interest and overdispersed count outcomes exhibiting many zeros. The regression coefficients of ZINB have latent class interpretations for a susceptible subpopulation at risk for the disease/condition under study with counts generated from a negative binomial distribution and for a non-susceptible subpopulation that provides only zero counts. The ZINB parameters, however, are not well-suited for estimating overall exposure effects, specifically, in quantifying the effect of an explanatory variable in the overall mixture population. In this paper, a marginalized zero-inflated negative binomial regression (MZINB) model for independent responses is proposed to model the population marginal mean count directly, providing straightforward inference for overall exposure effects based on maximum likelihood estimation. Through simulation studies, the finite sample performance of MZINB is compared with marginalized zero-inflated Poisson, Poisson, and negative binomial regression. The MZINB model is applied in the evaluation of a school-based fluoride mouthrinse program on dental caries in 677 children. Copyright © 2015 John Wiley & Sons, Ltd.

    Periodontal disease prevalence in children is an indicator of future disease burden in the adult population. Knowledge about the prevalence and risk status of periodontal disease in children can prove instrumental in the initiation of appropriate preventive and therapeutic measures. This school-based cross-sectional survey estimated the prevalence and severity of periodontal disease among 15-17-year-old children in Kozhikode district and assessed the risk factors. Multistage stratified random sampling and randomized cluster sampling were used in the selection of schools and study participants, respectively, in three educational districts of Kozhikode. Periodontal disease was assessed among 2000 school children aged 15-17 years, by community periodontal index. A content validated questionnaire was used to evaluate the sociodemographic characteristics and other risk factors. The prevalence of periodontal disease was estimated as 75% (72% gingivitis and 3% mild periodontitis). The prevalence was higher in urban population ( P = 0.049) and males had significantly ( P = 0.001) higher prevalence. Lower socioeconomic strata experienced slightly more periodontal disease burden. Satisfactory oral hygiene practices (material and frequency) were observed, but oral hygiene techniques were erroneous. Unhealthy dental treatment-seeking practices and unfavorable attitude toward dental treatment (ATDT) significantly influenced periodontal health status. Overall awareness about dental treatment was poor in this study population. The prevalence of periodontal disease among 15-17-year-old school children in Kozhikode district is 75% and is influenced by sociodemographic characteristics. Other risk factors identified were unhealthy dental treatment-seeking practices and unfavorable ATDT. Implementation of well-formulated oral health education programs is thus mandatory.

    Through the 2009 HITECH (Health Information Technology for Economic and Clinical Health) Act, the U.S. government committed $27 billion to incentivize the adoption and "meaningful use" of certified electronic health records (EHRs) by providers, including dentists. Given their patient profiles, dental school clinics are in a position to benefit from this time-delimited commitment to support the adoption and use of certified EHR technology under the Medicaid-based incentive. The benefits are not merely financial: rather, the meaningful use objectives and clinical quality measures can drive quality improvement initiatives within dental practices and help develop a community of medical and dental professionals focused on quality. This article describes how dentists can qualify as eligible providers and the set of activities that must be undertaken and attested to in order to obtain this incentive. Two case studies describe the approaches that can be used to meet the Medicaid threshold necessary to be eligible for the incentive. Dentists can and have successfully applied for meaningful use incentive payments. Given the diverse set of patients who are treated at dental schools, these dental practices are among those most likely to benefit from the incentive programs.

    Dental fear and anxiety in children and adolescents is a common problem. Hypnosis has been shown to be useful in the treatment of these patients. This paper briefly reviews conventional management skills before considering the application of hypnosis. Following a definition of hypnosis, the concepts of relaxation, restricted awareness, blunting of critical faculties and the enhanced capacity to respond to suggestion are outlined. Consideration is given to the induction of hypnosis and its general application in an informal and formal manner. The application of more specific techniques, such as the use of hypnoanalgesia to reduce physical discomfort and the development of coping strategies to help children overcome their fears, are discussed. It has been widely shown that hypnosis is a useful adjunct in dentistry. However, it is unfortunate that hypnosis is not more widely used as it has the potential for making conventional dental management more acceptable and reducing the number of children requiring general anaesthesia.

Materials and Methods: The study population comprised 400 school-going children of age 11–14 years. The severity of malocclusion was determined by Treatment Priority Index. The sociodemographic factors were evaluated using a questionnaire that enquired about age, gender, parents' monthly income, and their educational status. Periodontal status was assessed using Community Periodontal Index of Treatment Need (CPITN index. To know about dental caries, decayed, missing, filled teeth (DMFT index was used in this study. Statistical Analysis Used: Spearman's rank correlation coefficients were used to find an association between variables. The effect of sociodemographic factors on treatment priority index (TPI scores was examined using Chi-square test. Student's t-test (to compare TPI scores of different genders and analysis of variance (to compare TPI scores among different age groups were used in this study. Results: Out of a total of 400 children included in the study, 19.5% students had normal occlusion whereas a majority of them (80.5% showed some sort of malocclusion. CPITN scores revealed that 3.1% pupils had no sign of the disease, 57.5% showed gingival bleeding after gentle probing, and 39.4% had supra or subgingival calculus. Conclusions: No statistically significant correlation was found between the orthodontic treatment need, periodontal status, and sociodemographic factors while a significant relation is observed of TPI with DMFT.

    Full Text Available Background: Dental modifications are one of the forms of initiation rite. Thus tradition can be found in all of Indonesian regions, even in South East Asia, in previous era. Modes and dentistry, as a culture product, including its modifications or decorations toward body and teeth have appeared in present day, such as tattoo and decorations on teeth which are taken particular model and superimpose or inculcate ornament of jewel, diamond, gold and others. The first research aim is to describe how functions of modifications on teeth represent cultural affinity and population of biologic affinity that accompany it from time to time; starting from prehistoric period to present day, especially in Indonesian region. The second aim is to submit applicable proposal that is useful for medical area, particularly in dentistry. Method: The research materials include teeth of the adult human skulls of Java, Balinese, and East Nusa Tenggara from some paleoanthropological–archaeological sites, as well as isolated permanent dental sample from modern Balinese population. The methods used are visual comparative descriptive method, and browsed through ethnographic and archaeological classic literatures. Result: Chronologically, dental modifications as reference to the pattern of migration and the domination of the culture in the past, and these facts indicate to the biological affinity and indicate to how the culture influences other culture. Conclusion: Some effects of the practices of dental modifications are the emergence of some diseases. Therefore, it is necessary for the agent of health and the traditional practitioner to be aware when they practice the dental modifications. Nevertheless, on the other side, based on explanations the research results, it is clear that dental modifications provide broader knowledge, because it has a very long journey of migration history, occupancy, and culture in this Indonesian Archipelago, which stretches from the period

    In the past two decades the utilization of dental and orthopaedic implants in reconstructive surgery has been spread widely. Most of these implants are inserted in the corrosive environment of the human body for long periods of time. The level of dissolution, release, and transport of metal ions as a result of corrosion of these materials are not fully known at present. We report the results of application of micro ion beam PIXE spectroscopy to detect release of titanium from titanium and titanium alloy implants inserted in the tibiae of rabbits for three months. It was found that titanium ions could be detected in the surrounding tissues, with high precision, as a gradient from the implant surface and in higher amounts in the bone tissue as compared with the soft tissues. It is concluded that application of micro ion beam PIXE spectroscopy for detection of metal ion release, and distribution of the released material around the implants with high special resolution and accuracy may be used to further investigate the mechanism of metal release, and the relation between surface micromorphology and corrosion resistance of the implant materials.

    Ravindran, Sriram; George, Anne

    2015-01-01

    Dental caries is one of the most widely prevalent infectious diseases in the world. It affects more than half of the world's population. The current treatment for necrotic dental pulp tissue arising from dental caries is root canal therapy. This treatment results in loss of tooth sensitivity and vitality making it prone for secondary infections. Over the past decade, several tissue-engineering approaches have attempted regeneration of the dental pulp tissue. Although several studies have highlighted the potential of dental stem cells, none have transitioned into a clinical setting owing to limited availability of dental stem cells and the need for growth factor delivery systems. Our strategy is to utilize the intact ECM of pulp cells to drive lineage specific differentiation of bone marrow derived mesenchymal stem cells. From a clinical perspective, pulp ECM scaffolds can be generated using cell lines and patient specific somatic stem cells can be used for regeneration. Our published results have shown the feasibility of using pulp ECM scaffolds for odontogenic differentiation of non-dental mesenchymal cells. This focused review discusses the issues surrounding dental pulp tissue regeneration and the potential of our strategy to overcome these issues. PMID:25954205

    2015-01-01

    In this study, the application of transparent physical vapor deposition (PVD) coatings on zirconia ceramics was examined as an approach to retard the low-temperature degradation of zirconia for dental applications. Transparent monolayers of titanium oxide (TixOy) and multilayers consisting of titanium oxide-alumina-titanium oxide (TixOy-AlxOy-TixOy) were deposited onto standardized discs of 3Y-TZP using magnetron sputtering. Using X-ray photospectroscopy and time-of-flight secondary-ion mass spectrometry, the compositions of the coatings were verified, and an approximate thickness of 50 nm for each type of coating was ascertained. After aging the coated and uncoated samples in water vapor at 134°C and 3 bar for 4, 8, 16, 32, 64 and 128 h, the monoclinic phase content was determined using X-ray diffraction, and its impact on mechanical properties was assessed in biaxial flexural strength tests. In addition, the depth of the transformation zone was measured from scanning electron microscopy images of the fracture surfaces of hydrothermally aged samples. The results revealed that the tetragonal-to-monoclinic phase transformation of the zirconia ceramic was retarded by the application of PVD coatings. During the first stages of aging, the coated samples exhibited a significantly lower monoclinic phase content than the uncoated samples and, after 128 h of aging, showed a transformation zone which was only ∼12-15 μm thick compared to ∼30 μm in the control group. Biaxial flexural strength decreased by ∼10% during aging and was not influenced by the application of a PVD coating. Copyright © 2014 Acta Materialia Inc. Published by Elsevier Ltd.

  14. Processing and properties of ceramic matrix-polymer composites for dental applications

    Science.gov (United States)

    Huang, Hsuan Yao

    The basic composite structure of natural hard tissue was used to guide the design and processing of dental restorative materials. The design incorporates the methodology of using inorganic minerals as the main structural phase reinforced with a more ductile but tougher organic phase. Ceramic-polymer composites were prepared by slip casting a porous ceramic structure, heating and chemical treating the porous preform, infiltrating with monomer and then curing. The three factors that determined the mechanical properties of alumina-polymer composites were the type of polymer used, the method of silane treatments, and the type of bond between particles in the porous preforms. Without the use of silane coupling agents, the composites were measured to have a lower strength. The composite with a more "flexible" porous alumina network had a greater ability to plastically dissipate the energy of propagating cracks. However, the aggressive nature of the alumina particles on opposing enamel requires that these alumina-polymer composites have a wear compatible coating for practical application. A route to dense bioactive apatite wollastonite glass ceramics (AWGC)-polymer composites was developed. The problems associated with glass dissolution into the aqueous medium for slip casting were overcome with the use of silane. The role of heating rate and development of ceramic compact microstructure on composite properties was explored. In general, if isothermal heating was not applied, decreasing heating rate increased glass crystallinity and particle-particle fusion, but decreased pore volume. Also composite strength and fracture toughness decreased while modulus and hardness increased with decreasing heating rate. If isothermal heating was applied, glass crystallinity, pore content, and composite mechanical properties showed relatively little change regardless of the initial heating rate. The potential of AWGC-polymer composites for dental and implant applications was explored

    Full Text Available Abstract Background This was a retrospective cohort study undertaken to assess the rate and pattern of dental caries development in 6-year-old school children followed-up for a period of 5 years, and to identify baseline risk factors that were associated with 5 years caries experience in Malaysian children. Methods This 5-years retrospective cohort study comprised primary school children initially aged 6 years in 2004. Caries experience of each child was recorded annually using World Health Organization criteria. The rates of dental caries were recorded in prevalence and incidence density of carious lesions from baseline to final examination. Risk assessment was done to assess relative risk for caries after 5 years in children with baseline caries status. Simple and multiple logistic regression analysis were performed to identify significant independent risk factors for caries. Results The sample consisted of 1830 school children. All components of DMFT showed significant differences between baseline and final examination. Filled teeth (FT component of the DMFT showed the greatest increases. Results revealed the initial baseline caries level in permanent dentition was a strong predictor for future caries after 5 years (RR=3.78, 95% CI=3.48-4.10, P0.001. Logistic regression analysis showed significant association between caries occurrence and residence (urban/rural (OR=1.80, Pp observed from baseline and after 5 years was 5.80 persons/100 person-year of observation. The rate of new caries-affected tooth (IDt in the period from baseline and after 5-years was 0.76 teeth/100 teeth-year of observation. Conclusion The majority of 12-year-old school children (70% were caries-free and most of the caries were concentrated in only a small proportion (30% of them. We found that the presence of caries in permanent teeth at the age of 6 years was a strong predictor of future caries development in this population. The strong evidence of early permanent teeth

    Full Text Available Titanium β-type alloys attract attention as biomaterials for dental applications. The aim of this work was the synthesis of nanostructured β type Ti23Mo-x wt % 45S5 Bioglass (x = 0, 3 and 10 composites by mechanical alloying and powder metallurgy methods and their characterization. The crystallization of the amorphous material upon annealing led to the formation of a nanostructured β type Ti23Mo alloy with a grain size of approximately 40 nm. With the increase of the 45S5 Bioglass contents in Ti23Mo, nanocomposite increase of the α-phase is noticeable. The electrochemical treatment in phosphoric acid electrolyte resulted in a porous surface, followed by bioactive ceramic Ca-P deposition. Corrosion resistance potentiodynamic testing in Ringer solution at 37 °C showed a positive effect of porosity and Ca-P deposition on nanostructured Ti23Mo 3 wt % 45S5 Bioglass nanocomposite. The contact angles of glycerol on the nanostructured Ti23Mo alloy were determined and show visible decrease for bulk Ti23Mo 3 wt % 45S5 Bioglass and etched Ti23Mo 3 wt % 45S5 Bioglass nanocomposites. In vitro tests culture of normal human osteoblast cells showed very good cell proliferation, colonization, and multilayering. The present study demonstrated that porous Ti23Mo 3 wt % 45S5 Bioglass nanocomposite is a promising biomaterial for bone tissue engineering.

    Full Text Available The physical and chemical characteristics of diamond-like carbon (DLC films make them suitable for implantable medical and odontological interests. Despite their good interactions with biological environment, incorporated nanoparticles can significantly enhance DLC properties. This manuscript studies the potential of titanium dioxide (TiO2 incorporated-DLC films in dental applications. In this scene, both osteoblasts attachment and spreading on the coatings and their corrosion characteristics in artificial saliva were investigated. The films were grown on 304 stainless steel substrates using plasma enhanced chemical vapor deposition. Raman scattering spectroscopy characterized the film structure. As the concentration of TiO2 increased, the films increased the osteoblast viability (MTT assay, becoming more thermodynamically favorable to cell spreading (WAd values became more negative. The increasing number of osteoblast nuclei indicates a higher adhesion between the cells and the films. The potentiodynamic polarization test in artificial saliva shows an increase in corrosion protection when TiO2 are present. These results show the potential use of TiO2-DLC films in implantable surfaces.

    The study aims to assess the reliability of video-graphic method as a tool to screen the dental caries among 12-year-old school children in a rural region of India. A total of 139 school children participated in the study. Visual tactile examinations were conducted using the Decayed, Missing, and Filled Teeth (DMFT) index. Simultaneously, standardized video recording of the oral cavity was performed. Sensitivity and specificity values were calculated for video-graphic assessment of dental caries. Bland-Altman plot was used to assess agreement between the two methods of caries assessment. Likelihood ratio (LR) and receiver-operating characteristic (ROC) curve were used to assess the predictive accuracy of the video-graphic method. Mean DMFT for the study population was 2.47 ± 2.01 and 2.46 ± 1.91 by visual tactile and video-graphic assessment (P = 0.76; > 0.05). Sensitivity and specificity values of 0.86 and 0.58 were established for video-graphic assessment. A fair degree of agreement was noted between the two methods with Intraclass correlation coefficient (ICC) value of 0.56. LR for video-graphic assessment was 2.05. Bland-Altman plot confirmed the level of agreement between the two assessment methods. The area under curve was 0.69 (CI 0.57, 0.80, P = 0.001). Teledentistry examination is comparable to clinical examination when screening for dental caries among school children. This study provides evidence that teledentistry may be used as an alternative screening tool for assessment of dental caries and is viable for remote consultation and treatment planning. Teledentistry offers to change the dynamics of dental care delivery and may effectively bridge the rural-urban oral health divide. © 2016 American Association of Public Health Dentistry.

    Full Text Available Aim and Objectives: To correlate dental caries experience with pH, buffering capacity and flow rate of saliva among 15-year-old-children Materials & Method : Fifteen year old school children from adopted schools of a dental college in Mangalore were considered as study subjects. The study was carried out using a standardized proforma that consisted of questionnaire for recording demographic data. The caries experience was assessed by DMFT Index. Salivary pH was measured by using a pH meter and salivary buffering capacity was measured by using titration method. Unstimulated whole saliva was collected from all subjects by direct expectoration to calculate the flow rate. Results: The mean DMFT of the study population was 2.85 ± 2.5. The mean salivary pH was found to be 6.88 ± 0.69.About 74.1% were having medium salivary buffering capacities. The mean unstimulated salivary flow rate and mean total antioxidant capacity of the study population was 0.41 ± 0.14 ml/min and 94.15 ± 60.72 g/dL respectively. Conclusions: A marked association between the pH, buffering capacity and unstimulated flow rate with dental caries experience suggest that assessment of these salivary parameters can be used as predictors for future dental caries susceptibility in an individual.

  1. Teeth and bones: applications of surface science to dental materials and related biomaterials

    2001-05-01

    Recent years have seen a considerable upsurge in publications concerning the surface structure and chemistry of materials with biological or biomedical applications. Within the body, gas-solid interactions become relatively less significant and solid-liquid or solid-solid interfaces dominate, providing new challenges for the surface scientist. The current paper aims to provide a timely review of the use of surface analysis and modification techniques within the biomaterials field. A broad overview of applications in a number of related areas is given with particular attention focusing on those materials commonly encountered in dentistry and oral or maxillofacial implantology. Several specific issues of current interest are discussed. The interaction between synthetic and natural solids, both in the oral environment and elsewhere in the body is important in terms of adhesion, related stresses and strains and ultimately the longevity of a dental restoration, biomedical implant, or indeed the surrounding tissue. Exposure to body fluids, of course, can also affect stability, leading to the degradation or corrosion of materials within the body. Whilst this could potentially be harmful, e.g., if cytotoxic elements are released, it may alternatively provide a route to the preferential release of beneficial substances. Furthermore, in some cases, the controlled disintegration of a biomaterial is desirable, allowing the removal of an implant, e.g., without the need for further surgery. The presence of cells in the immediate bioenvironment additionally complicates the situation. A considerable amount of current research activity is targeted at the development of coatings or surface treatments to encourage tissue growth. If this is to be achieved by stimulating enhanced cell productivity, determination of the relationship between cell function and surface composition is essential.

    Growing distribution and utilization of digital volume tomography (DVT) extend the spectrum of clinical dental imaging. Additional diagnostic value, however, comes along with an increasing amount of radiation. In contrast, magnetic resonance imaging is a radiation free imaging technique. Furthermore, it offers a high soft tissue contrast. Morphological and numerical dental anomalies, differentiation of periapical lesions and exclusion of complications of dental diseases are field of applications for dental MRI. In addition, detection of caries and periodontal lesions and injury of inferior alveolar nerve are promising application areas in the future.

    Student advocacy and involvement in the political process is built into the structure of the American Student Dental Association (ASDA), especially in its Legislative Grassroots Network and an internal communication network among students to ensure political awareness. Students are concerned with such issues as a universally accepted, non-patient-based licensure process, mid-level providers, loan availability and tax deductibility, financial support for schools, and service early in one's professional career (giving forward rather than giving back). Through collaboration with the American Dental Education Association and with many state associations, students participate in lobbying, awareness campaigns, and behind the scenes as legislative aids. Although students share the same love for the profession that animates established practitioners, they are perceived by legislators as being different. Students are involved in the legislative process because it represents their future.

    Tooth sensitivity commonly occurs during and immediately after dental bleaching. The authors conducted a trial to compare tooth sensitivity after in-office bleaching after the use of either a topical dipyrone or placebo gel. A split-mouth, triple-blind, randomized, multicenter clinical trial was conducted among 120 healthy adults having teeth that were shade A2 or darker. The facial tooth surfaces of the right or left sides of the maxillary arch of each patient were randomly assigned to receive either topical dipyrone or placebo gel before 2 in-office bleaching sessions (35% hydrogen peroxide) separated by 2 weeks. Visual analog and numerical rating scales were used to record tooth sensitivity during and up to 48 hours after bleaching. Tooth color change from baseline to 1 month after bleaching was measured with shade guide and spectrophotometer measures. The primary outcome variable was absolute risk of tooth sensitivity. An intention-to-treat analysis was used to analyze data from all patients who were randomly assigned to receive the dipyrone and placebo gels. No statically significant difference was found in the absolute risk of tooth sensitivity between the dipyrone and placebo gels (83% and 90%, respectively, P = .09; relative risk, 0.92; 95% confidence interval, 0.8 to 1.0). A whitening effect was observed in both groups with no statistically significant difference (P > .05) between them. No adverse effects were observed. Topical use of dipyrone gel before tooth bleaching, at the levels used in this study, did not reduce the risk or intensity of bleaching-induced tooth sensitivity. Topical application of dipyrone gel does not reduce bleaching-induced tooth sensitivity. Copyright © 2018 American Dental Association. Published by Elsevier Inc. All rights reserved.

    2016-12-01

    Prior to the introduction of the Southern District Health Board's reconfigured Community Oral Health Service in Otago, a project was undertaken with parents to investigate their knowledge, understanding and views of the historical School Dental Service and of the Community Oral Health Service that was being introduced. Focus groups were run during 2011 in ten selected schools (parents with children in years 1-8) across two areas in Otago to represent ur ban and rural settings and to represent parents who were already travelling to dental services. Parents valued the traditional School Dental Service in Otago highly, generally agreeing that the service based in schools was accessible and convenient for parents and children. Rural parents who had always taken their children to dental appointments viewed it as a normal process, accepting that there could not be a service located in every school. Parents were aware that facilities were out-of-date. They highlighted the challenges of locating therapists since they started moving from school to school in the later 1990s and felt it was difficult for children seeing different therapists at each recall. There were diverse views on the proposed new system. Some parents felt that school-aged children should go to dental clinics on their own or with peers, while other parents welcomed the opportunity to attend when their child was having health care. It appears that the Community Oral Health Services should have an ongoing process to seek the views of parents and children about the service.

  10. Application of the human needs conceptual model of dental hygiene to the role of the clinician : part II.

    Walsh, M M; Darby, M

    1993-01-01

    In summary, the theories of Maslow and of Yura and Walsh have been highlighted as background for understanding the human needs conceptual model of dental hygiene. In addition, 11 human needs have been identified and defined as being especially related to dental hygiene care, and a sample evaluation tool for their clinical assessment and a dental hygiene care plan have been presented. The four concepts of client, environment, health/oral health, and dental hygiene actions explained in terms of human need theory, and the 11 human needs related to dental hygiene care constitute the human needs conceptual model of dental hygiene. Within the framework of the human needs conceptual model of dental hygiene, the dental hygiene process is a systematic approach to dental hygiene care that involves assessment of the 11 human needs related to dental hygiene care; analysis of deficits in these needs; determination of the dental hygiene care plan based on identified deficits; implementation of dental hygiene interventions stated in the care plan; and evaluation of the effectiveness of dental hygiene interventions in achieving specific goals, including subsequent reassessment and revision of the dental hygiene care plan. This human needs conceptual model for dental hygiene provides a guide for comprehensive and humanistic client care. This model allows the dental hygienist to view each client (whether an individual or a group) holistically to prevent oral disease and to promote health and wellness. Dental hygiene theorists are encouraged to expand this model or to develop additional conceptual models based on dental hygiene's paradigm.

    UK dental schools are reliant on part-time teachers to deliver the clinical educational component of the course, the majority with a background in general dental practice. Opportunities for promotion are limited, as is the support for obtaining educational qualifications. The aim of this study was to ascertain the views of such teachers at a dental school. An anonymous online survey was used to obtain both qualitative and quantitative views. The response rate was 80%. The school has n = 50 part-time clinical teachers, who have been teaching for, on average ten years, and for three sessions per week. Eighteen percent of teachers are recognised specialists. Forty-six percent of respondents have a formal teaching qualification, mostly at certificate level, and 55% thought it necessary to acquire a formal teaching qualification. Eighty-eight percent were happy with their role as clinical teachers. This study demonstrates that despite the lack of support and prospect of career progression, the majority of part-time clinical teachers at this institution are satisfied with their role.

    Objectives To investigate the prevalence of obesity among elementary school children and to examine the association between obesity and caries activity in the mixed dentition stage. Methods This cross-sectional study was conducted in King Abdulaziz University, Jeddah, Kingdom of Saudi Arabia between September 2014 and June 2015 using a multi-stage stratified sample of 915 elementary school children (482 boys, 433 girls) in Jeddah, Saudi Arabia. Anthropometric measurements, consisting of height, weight, body mass index (BMI), and waist circumference (WC), were obtained. Children were classified as underweight/healthy, overweight, or obese and as non-obese or obese according to their BMI and WC, respectively. Each child’s caries experience was assessed using the decay score in the primary and permanent teeth. Results Based on BMI, 18% of children were obese, 18% were overweight, and 64% were underweight/normal. Based on WC, 16% of children were obese, and 84% were non-obese. Girls had a significantly higher prevalence of obesity based on WC measurements (p<0.001), but not BMI. Children enrolled in private schools had a significantly higher prevalence of obesity (p<0.05) than those in public schools. For primary and permanent teeth combined, children with higher BMI and WC had a lower prevalence of caries (p<0.05). Conclusion The prevalence of obesity was high among male and female elementary school children. Overall caries activity was inversely proportional to BMI and WC. PMID:27874156

    Full Text Available Orthodontic treatments often lead to biofilm buildup and white spot lesions due to enamel demineralization. The objectives of this study were to develop a novel bioactive orthodontic cement to prevent white spot lesions, and to determine the effects of cement compositions on biofilm growth and acid production. 2-methacryloyloxyethyl phosphorylcholine (MPC, nanoparticles of silver (NAg, and dimethylaminohexadecyl methacrylate (DMAHDM were incorporated into a resin-modified glass ionomer cement (RMGI. Enamel shear bond strength (SBS was determined. Protein adsorption was determined using a micro bicinchoninic acid method. A dental plaque microcosm biofilm model with human saliva as inoculum was used to investigate metabolic activity, colony-forming units (CFU and lactic acid production. Incorporating 3% of MPC, 1.5% of DMAHDM, and 0.1% of NAg into RMGI, and immersing in distilled water at 37 °C for 30 days, did not decrease the SBS, compared to control (p > 0.1. RMGI with 3% MPC + 1.5% DMAHDM + 0.1% NAg had protein amount that was 1/10 that of control. RMGI with triple agents (MPC + DMAHDM + NAg had much stronger antibacterial property than using a single agent or double agents (p < 0.05. Biofilm CFU on RMGI with triple agents was reduced by more than 3 orders of magnitude, compared to commercial control. Biofilm metabolic activity and acid production were also greatly reduced. In conclusion, adding MPC + DMAHDM + NAg in RMGI substantially inhibited biofilm viability and acid production, without compromising the orthodontic bracket bond strength to enamel. The novel bioactive cement is promising for orthodontic applications to hinder biofilms and plaque buildup and enamel demineralization.

    To synthesize a glass-ceramic (GC) that is suitable for non-metallic one-piece dental implant application. Three glasses in a SiO2-Al2O3-CaO-CaF2-K2O-B2O3-P2O5-CeO2-Y2O3 system were produced by wet chemistry. Differential thermal analysis (DTA) was carried out to determine the glass crystallization kinetic parameters and the heating schedules that were used for sintering of GCs. Crystalline phases and crystal morphologies were studied by X-ray diffraction (XRD) and scanning electron microscopy (SEM), respectively. Mechanical properties of the GCs were determined by ultrasonic and indentation tests and its machinability were evaluated. Chemical durability was carried out according to ISO 6872, whereas testing chemical degradation in tris buffered solution was executed according to ISO 10993-14. XRD of the GC specimens showed that wollastonite was the main crystalline with other secondary phases; GC2 had cristobalite as an additional phase. SEM of the GCs revealed dense acicular interlocking crystals. Young's modulus of elasticity (E), true hardness (Ho) and fracture toughness (KIC) of the GCs were 89-100GPa, 4.85-5.17GPa and 4.62-5.58MPam(0.5), respectively. All GCs were demonstrated excellent machinability. The GCs exhibited various chemical durability and degradation rates. KIC values of the GCs following chemical durability testing were not significantly different from those of the original materials (p>0.05). GC2 exhibited significantly higher KIC value compared with GC1 and GC3 (pmachinability and chemical durability. Copyright © 2014. Published by Elsevier Ltd.

    This study aimed at preparation and in vitro and in vivo evaluation of novel bioactive, biodegradable, and antibacterial nanocomposite coating for the improvement of stem cells attachment and antibacterial activity as a candidate for dental implant applications. Poly (lactide-co-glycolide)/bioactive glass/hydroxyapatite (PBGHA) nanocomposite coating was prepared via solvent casting process. The nanoparticle amounts of 10, 15, and 20 weight percent (wt%) were chosen in order to determine the optimum amount of nanoparticles suitable for preparing an uniform coating. Bioactivity and degradation of the coating with an optimum amount of nanoparticles were evaluated by immersing the prepared samples in simulated body fluid and phosphate buffer saline (PBS), respectively. The effect of nanocomposite coating on the attachment and viability of human adipose-derived stem cells (hASCs) was investigated. Kirschner wires (K-wires) of stainless steel were coated with the PBGHA nanocomposite coating, and mechanical stability of the coating was studied during intramedullary implantation into rabbit tibiae. The results showed that using 10 wt% nanoparticles (5 wt% HA and 5 wt% BG) in the nanocomposite could provide the desired uniform coating. The study of in vitro bioactivity showed rapid formation of bone-like apatite on the PBGHA coating. It was degraded considerably after about 60 days of immersion in PBS. The hASCs showed excellent attachment and viability on the coating. PBGHA coating remained stable on the K-wires with a minimum of 96% of the original coating mass. It was concluded that PBGHA nanocomposite coating provides an ideal surface for the stem cells attachment and viability. In addition, it could induce antibacterial activity, simultaneously.

    In 1921, New Zealand began training school dental nurses, subsequently deploying them throughout the country in school-based clinics providing basic dental care for children. The concept of training dental nurses, later to be designated dental therapists, was adopted by other countries as a means of improving access to care, particularly for children. This paper profiles six countries that utilise dental therapists, with a description of the training that therapists receive in these countries, and the context in which they practice. Based on available demographic information, it also updates the number of dental therapists practising globally, as well as the countries in which they practice. In several countries, dental therapy is now being integrated with dental hygiene in training and practice to create a new type of professional complementary to a dentist. Increasingly, dental therapists are permitted to treat adults as well as children. The paper also describes the status of a current initiative to introduce dental therapy to the United States. It concludes by suggesting that dental therapists can become valued members of the dental team throughout the world, helping to improve access to care and reducing existing disparities in oral health.

    Full Text Available Abstract Background Smoking is currently accepted as a well-established risk factor for many oral diseases such as oral cancer and periodontal disease. Provision of smoking cessation care to patients with oral problems is a responsibility of health care professionals, particularly dentists and dental hygienists. This study examined the smoking-related perceptions and practices of dental school hospital-based health professionals in Japan. Findings A cross-sectional study design was used. The sample was formed from dentists, dental hygienists, physicians and nurses of a dental school hospital in Tokyo, Japan (n = 93, 72%. Participants were asked to complete an 11-item questionnaire assessing demographic variables and smoking history, provision of smoking cessation advice or care, attitudes about smoking cessation, and perceived barrier(s to smoking cessation care. Eighteen percent of participants reported being current smokers and 15% reported being ex-smokers, with higher smoking rates reported by dentists compared with other health professionals (p = 0.0199. While recognizing the importance of asking patients about their smoking status, actual provision of smoking cessation advice or care by participants was relatively insufficient. Interventions such as 'assess willingness to make a quit attempt' and 'assist in quit attempt' were implemented for less than one-quarter of their patients who smoke. Non-smokers were more likely to acknowledge the need for increased provision in smoking cessation care by oral health professionals. 'Lack of knowledge and training' was identified as a central barrier to smoking cessation care, followed by 'few patients willing to quit'. Conclusions A need for further promotion of smoking cessation activities by the health professionals was identified. The findings also suggest that dentists and dental hygienists, while perceiving a role in smoking care, do require training in the provision of smoking cessation care

    The purpose of this study was to develop and evaluate an application (app) facilitating patient-professional communication among individuals with autism spectrum disorder (ASD) and compare it with the Picture Exchange Communication System (PECS). Forty nine- to 15-year-olds were randomly divided into two groups: G1 (app; N equals 20) and G2 (PECS; N equals 20). Initially, the visual contact timing of the groups was measured. Pictures of a room, ground, chair, dentist, mouth, low-speed handpiece, and air-water syringe were presented to both groups. Each picture was shown up to three times per appointment to evaluate whether or not the child accepted the procedure. After dental prophylaxis, caries experience was recorded. The prevalence of dental caries was 37.5 percent. Differences in the number of attempts required for each picture to acquire the skill proposed were found between the groups (Mann-Whitney, PPicture Exchange Communication System for dentist-patient communication, decreasing the number of appointments required for preventive dental care and clinical examinations.

    Every year millions of people seek dental treatment to either repair damaged, unaesthetic and dysfunctional teeth or replace missing natural teeth. Several dental materials have been developed to meet the stringent requirements in terms of mechanical properties, aesthetics and chemical durability in the oral environment. Glass-ceramics exhibit a suitable combination of these properties for dental restorations. This research is focused on the assessment of the thermomechanical behavior of bio-ceramics and particularly lithium aluminosilicate glass-ceramics (LAS glass-ceramics). Specifically, methodologies based on Infrared Thermography (IRT) have been applied in order the structure - property relationship to be evaluated. Non-crystallized, partially crystallized and fully crystallized glass-ceramic samples have been non-destructively assessed in order their thermo-mechanical behavior to be associated with their micro-structural features.

    2016-09-01

    To enhance the reader's critical thinking when reading the dental literature on the relationship of occlusion and myogenous orofacial pain (MOP). Representative journal articles and systematic reviews from the dental literature confirming and denying a relationship of occlusion to MOP were analyzed and reviewed. Studies using computerized occlusal analysis (COA) consistently find a relationship of the occlusion to MOP. Studies that do not confirm this relationship have problems with invalid primary source conclusions, unstated assumptions, bias, and errors in logic that disqualify their conclusion. This review explains four categories of problems with the dental literature that denies occlusion has a relationship with MOP. When the reader understands these examples of flaws in this literature, they can apply this critical thinking to future studies. Correct interpretation of the literature on occlusion and MOP requires a foundation of basic and clinical scientific knowledge as well as an understanding of the details of the primary source articles.

    A case study is used to illustrate how an evaluation strategy was used to assess classroom instructional practices following a multiyear institutional curriculum revision process. From January through April of 2003, twelve faculty in medicine and three faculty in dentistry who taught in the first- and second-year basic science courses within the dental curriculum participated in a qualitative study. The purpose was to use a formative evaluation process to assess the impact of the curriculum revision at the level of classroom instruction. The observations revealed that seventeen of the twenty classes observed were teacher-centered, passive, and lacked observable effort to help students understand the relationship of the lecture content to the oral health problems. Findings illustrate the importance of using formative evaluation as a mechanism to assess change efforts and how evidence-based study can be used to support initiatives directed toward assessing active student learning and problem solving. Raising faculty awareness about the importance of acquiring evidence-based educational skills, aligning instruction with course goals and objectives, formatively assessing teaching, and providing learning experiences that will actually be used in practice are essential to ensuring that active learning and critical thinking are demonstrated in the curriculum.

    This was to establish the level and reported value of paediatric IHS experience from the perspective of final year undergraduates and to evaluate whether those students with more experience expressed feeling better-prepared for future practice and more likely to undertake further postgraduate education in IHS. All final year students were invited to complete an anonymous questionnaire designed to elicit undergraduate perceptions of IHS using visual analogue scales and free-text questions. A response rate of 77 % was achieved. Results revealed that only 21 % of participants reported acting as operator sedationist in ten or more IHS cases. Thus, the majority of undergraduates' did not meet the recommended quantity of practical IHS experiences, as outlined by the British Dental Sedation Teachers Group. In general, students felt on the value of IHS in the management of anxious children and expressed a desire to undertake further postgraduate education in conscious sedation. However, those students with more experience of practical IHS expressed feeling better able to describe the IHS experience with patients and parents, and were more satisfied with the quality of teaching. Furthermore free-text comments revealed that, regardless of experience, students wished to gain more experience of the practical administration of IHS. There is a need to increase the provision of IHS training within an undergraduate curriculum, in addition to improving the accessibility of postgraduate sedation courses.

Anthropometric measurements, consisting of height, weight, body mass index (BMI), and waist circumference (WC), were obtained. Children were classified as underweight/healthy, overweight, or obese and as non-obese or obese according to their BMI and WC, respectively. Each child's caries experience was assessed using the decay score in the primary and permanent teeth. Results: Based on BMI, 18% of children were obese, 18% were overweight, and 64% were underweight/normal. Based on WC, 16% of children were obese, and 84% were non-obese. Girls had a significantly higher prevalence of obesity based on WC measurements (p less than 0.001), but not BMI. Children enrolled in private schools had a significantly higher prevalence of obesity (p less than 0.05) than those in public schools. For primary and permanent teeth combined, children with higher BMI and WC had a lower prevalence of caries (p less than 0.05). Conclusion: The prevalence of obesity was high among male and female elementary school children. Overall caries activity was inversely proportional to BMI and WC.

    The aim of this study was to understand how new mobile technologies, such as smartphones and laptops, are used by dental students. A questionnaire was distributed to undergraduate dental students from years 1 to 4, at the University of Birmingham Dental School. Questionnaires were completed between February and April 2013. Two hundred and seventy questionnaires were completed. Laptops 55% (145) and smartphones 34% (88) were the most popular choice of device for connecting to the net and searching information. Laptops were preferred in first and second year. Students in year 3 preferred mobile phones, and by year 4 the use of mobile phones and laptops was similar. The top two application ideas chosen by students as the most useful on their smart phones were a dictionary for dental education (56%) and multiple choice questions (50%). Students who chose smartphones as their first choice or second choice of device strongly agreed that having the Internet on their smartphones had a positive impact on their dental education (55%). With laptops (48%), students preferred to be at home when using them while for smartphones (31%) they used them anywhere with a connection. E-mail (47%) and social networks (44%) were the top two Internet communication tools used most on laptops. Instant messaging was popular on smartphones (17%). Depending on the year in the course, laptops and smartphones are the most popular choice of device and desktop computers are the least popular. Applications on smartphones are very popular and instant messaging is an upcoming form of communication for students.

    Background and aims Accurate differential diagnosis between radicular cysts and periapical granulomas cannot be made from radiographs alone. Histological prevalence studies, therefore, assume special importance and may aid the clinician in making judgments regarding therapy. The incidence of radicular cysts has ranged with wide discrepancies in data. The purpose of this study was to evaluate recorded pathologic reports of two common types of chronic periapical lesion in Shiraz Dental School. Materials and methods In this study, biopsy reports of 227 specimens of chronic periapical lesions were reviewed. The following information was extracted from each report: patient’s gender, age, tooth associated with the lesion and the pathological diagnosis. Probable significant differences in the occurrence of lesions between different ages and genders were analyzed using chi-square test. Results 15.9% of the lesions were granulomas, and 84.1% were cysts. A slight difference in the occurrence of the lesions was found between males and females with no statistical significance (P > 0.005). The highest incidence of both lesions was in the third decade of life. No significant differences were found in age distribution of the lesions. The most common location for two lesions was the maxillary anterior teeth. Conclusion Histological differentiation between cysts and granulomas is not always accurate and serial sectioning of excisional biopsies is more valuable than randomized sectioning of curetted biopsies.

    Epoxy (EP) resins have been employed in dentistry for years, but their intrinsic brittleness demands a reinforcement to make them an ideal dental material that combines strength, toughness, and aesthetics. In this study, an EP resin was reinforced with a low-molecular-weight polyimide (PI). The PI/EP composites were subjected to three-point bending tests and examined by the scanning electron microscopy. It was found that blending PI with EP in proper proportions strengthened EP without sacrificing its toughness. The PI/EP composite could be employed in dentistry as the matrix of fiber-reinforced dental root canal posts.

    We have developed a hand-held fiber optic based optical coherence tomography (OCT) system for scanning of the oral cavity. We have produced, using this scanning device, in vivo cross-sectional images of hard and soft dental tissues in human volunteers. Clinically relevant anatomical structures, including the gingival margin, periodontal sulcus, and dento- enamel junction, were visible in all the images. The cemento- enamel junction and the alveolar bone were identified in approximately two thirds of the images. These images represent, or our knowledge, the first in vivo OCT images of human dental tissue.

    There is a dearth of published literature that demonstrates the impact and effectiveness of school-based oral health education (OHE) program in Bangladesh and it is one of the most neglected activities in the field of public health. Keeping this in mind, the objectives of this study were to assess the effectiveness of OHE program in: 1) increasing oral health knowledge, attitude, and practices and 2) decreasing the prevalence of untreated dental caries among 6-8 grade school students in Bangladesh. This intervention study was conducted in Araihazar Thana, Narayanganj district, Bangladesh during April 2012 to March 2013. The total participants were 944 students from three local schools. At baseline, students were assessed for oral health knowledge, attitude and practices using a self-administered structured questionnaire and untreated dental caries was assessed using clinical examination. Follow up study was done after 6 months from baseline. McNemar's chi-square analysis was used to evaluate the impact of OHE program on four recurrent themes of oral health between the baseline and follow-up. Multiple logistic regression analyses were used to determine the impact of the intervention group on our outcome variables. Significant improvement was observed regarding school aged adolescents' self-reported higher knowledge, attitude and practices scores (p level of knowledge regarding oral health compared to baseline. Compared with baseline participants in the follow-up were 1.89 times (95 % CI = 1.44-2.87) more likely to have higher attitude towards oral health. In addition, OHE intervention was found to be significantly associated with higher level of practices toward oral health (AOR = 1.64; 95 % CI = 1.12, 3.38). This study indicated that OHE intervention was effective in increasing i) knowledge, ii) attitude, and iii) practices towards oral health; it also significantly reduced the prevalence of untreated dental caries among school aged adolescents from grade 6-8 in a

    Current preventive measures against infectious oral diseases are mainly focussed on plaque removal and promoting a healthy lifestyle. This in vitro study investigated a third preventive method: maintaining healthy dental plaque with the use of small molecules. As a model of dental plaque, in vitro biofilms were cultivated under conditions that induce pathogenic characteristics. The effect of erythritol and other small molecules on the pathogenic characteristics and bacterial composition of the biofilm was evaluated. The artificial sweetener erythritol and the molecule 3-Oxo-N-(2-oxycyclohexyl)dodecanamide (3-Oxo-N) had no clinically relevant effect on total biofilm formation. Erythritol did, however, lower the gingivitis related protease activity of the biofilm, while 3-Oxo-N blocked the caries related lactic acid accumulation. Furthermore, both substances ensured the biofilm maintained a young, non-pathogenic microbial composition. This shows it is possible to influence the dental plaque in a positive manner in vitro with the help of small molecules. Further research is necessary before this manipulation of dental plaque can be applied.

    Conclusions: The findings suggest that bond strength of resin to bleached dentin may be affected with the adhesive system. Reduced SBS to bleached dentin can be amended by the use of SA as an antioxidizing agent. However, the amount of reversed bond strength subsequent to applying antioxidant might be related to the kind of dental adhesive.

    Full Text Available Dental Mesenchymal Stem Cells (MSCs, including Dental Pulp Stem Cells (DPSCs, Stem Cells from Human Exfoliated Deciduous teeth (SHED, and Stem Cells From Apical Papilla (SCAP, have been extensively studied using highly sophisticated in vitro and in vivo systems, yielding substantially improved understanding of their intriguing biological properties. Their capacity to reconstitute various dental and nondental tissues and the inherent angiogenic, neurogenic, and immunomodulatory properties of their secretome have been a subject of meticulous and costly research by various groups over the past decade. Key milestone achievements have exemplified their clinical utility in Regenerative Dentistry, as surrogate therapeutic modules for conventional biomaterial-based approaches, offering regeneration of damaged oral tissues instead of simply “filling the gaps.” Thus, the essential next step to validate these immense advances is the implementation of well-designed clinical trials paving the way for exploiting these fascinating research achievements for patient well-being: the ultimate aim of this ground breaking technology. This review paper presents a concise overview of the major biological properties of the human dental MSCs, critical for the translational pathway “from bench to clinic.”

    Three-dimensional (3D)-woven noncrimp fiber-reinforced composite (FRC) was tested for mechanical properties in the two principal directions of the main XY plane and compared to different Computer-Aided-Design/Computer-Aided-Machining (CAD/CAM) Dental Materials. The Dental Materials included ceramic with Vitablock Mark II®, ProCAD®, InCeram® Spinel, InCeram® Alumina and InCeram® Zirconia in addition to a resin-based 3M Corp. Paradigm® particulate-filled composite. Alternate material controls included Coors 300 Alumina Ceramic and a tungsten carbide 22% cobalt cermet. The 3D-woven FRC was vacuum assisted resin transfer molding processed as a one-depth-thickness ~19-mm preform with a vinyl-ester resin and cut into blocks similar to the commercial CAD/CAM Dental Materials. Mechanical test samples prepared for a flexural three-point span length of 10.0 mm were sectioned for minimum-depth cuts to compare machinability and fracture resistance between groups. 3D-woven FRC improved mechanical properties with significant statistical differences over all CAD/CAM Dental Materials and Coors Alumina Ceramic for flexural strength (p<0.001), resilience (p<0.05), work of fracture (p<0.001), strain energy release (p<0.05), critical stress intensity factor (p<0.001) and strain (p<0.001).

    As a continuation of our digital radiographic sensor R and D, we have developed a prototyped digital panoramic X-ray imaging system for dental applications. The imaging system consists of a slit-collimated X-ray generator with a 0.4 mm focal spot size and a 3.5 mm Al filtration, a linear-array typed CMOS imager with a 48x48 μm 2 pixel size and a 128 (in the scan direction)x3072 (in the vertical direction) pixel format, a series of microstep motors for the precise motion control of the imaging system, and the designed sequences for the motion control and pixel readout required to make a specific plane of interest (POI) to be focused. With the several test phantoms we designed, we obtained useful digital panoramic X-ray images by moving the X-ray generator and the CMOS imager along a continuously sliding rotational center. In this study, we demonstrated that the prototype system can be applicable to any shaped POI or multi-POIs simultaneously to be focused, provided that adequate sequences for motion control and pixel readout are designed. We expect that the imaging system will be useful for our ongoing applications of dental panoramic radiography and nondestructive testing.

    Titanium (Ti) is commonly used in dental implant applications. Surface modification strategies are being followed in last years in order to build Ti oxide-based surfaces that can fulfill, simultaneously, the following requirements: induced cell attachment and adhesion, while providing a superior corrosion and tribocorrosion performance. In this work micro-arc oxidation (MAO) was used as a tool for the growth of a nanostructured bioactive titanium oxide layer aimed to enhance cell attachment and adhesion for dental implant applications. Characterization of the surfaces was performed, in terms of morphology, topography, chemical composition and crystalline structure. Primary human osteoblast adhesion on the developed surfaces was investigated in detail by electronic and atomic force microscopy as well as immunocytochemistry. Also an investigation on the early cytokine production was performed. Results show that a relatively thick hybrid and graded oxide layer was produced on the Ti surface, being constituted by a mixture of anatase, rutile and amorphous phases where calcium (Ca) and phosphorous (P) were incorporated. An outermost nanometric-thick amorphous oxide layer rich in Ca was present in the film. This amorphous layer, rich in Ca, improved fibroblast viability and metabolic activity as well as osteoblast adhesion. High-resolution techniques allowed to understand that osteoblasts adhered less in the crystalline-rich regions while they preferentially adhere and spread over in the Ca-rich amorphous oxide layer. Also, these surfaces induce higher amounts of IFN-γ cytokine secretion, which is known to regulate inflammatory responses, bone microarchitecture as well as cytoskeleton reorganization and cellular spreading. These surfaces are promising in the context of dental implants, since they might lead to faster osseointegration. Copyright © 2015 Elsevier B.V. All rights reserved.

    When the CERN Accelerator School (CAS) was set up over ten years ago it was expected that its job of training a new generation of accelerator scientists would slacken off after a few years as recruitment eased back. It has therefore been a puzzle to explain why, a decade later, there is still a steady flow of 200 or 300 participants a year coming to CAS Courses. The explanation seems to be that the ''graduates'' are from the many laboratories considerably smaller than CERN and from university physics departments and hospitals where accelerators are used. There are also factories and even production lines where small accelerators are produced

    The properties of dental mould polymeric materials are strongly influenced by the chemical structure of both the polymer and the catalyst used in the crosslink reaction between them. In order to characterize and suggest some modifications on the materials interfacial interactions, mixtures of Polymer-catalyst were prepared. The polymer and the catalyst chemical structures were obtained by 13 C, 1 H and 129 Si NMR analysis in solution state. From the solution NMR results it was obtained the structure of the polymer and the catalyst and also the kind of the crosslink reaction taken. The CPMAS 1 '3C NMR analysis in the solid state were used to identify chemical structure of the polymeric dental moulded sample. (author)

    The purposes of this study were to apply the latest developments in additive manufacturing (AM) construction and to evaluate the effectiveness of these computer-aided design and computer-aided manufacturing (CAD/CAM) techniques in the production of dental appliances. In addition, a new method of incorporating wire into a single build was developed. A scanner was used to capture 3-dimensional images of Class II Division 1 dental models that were translated onto a 2-dimensional computer screen. Andresen and sleep-apnea devices were designed in 3 dimensions by using FreeForm software (version 11; Geo Magics SensAble Group, Wilmington, Mass) and a phantom arm. The design was then exported and transferred to an AM machine for building. Copyright © 2012 American Association of Orthodontists. Published by Mosby, Inc. All rights reserved.

    Handling (stickiness, adaptability) of a dental composite does strongly influence quality and success of a dental restoration. The purpose was to develop an in vitro test, which allows for evaluating adaptability and stickiness. 15 dentists were asked for providing individual assessment (school scores 1-6) of five dental composites addressing adaptability and stickiness. Composites were applied with a dental plugger (d=1.8 mm) in a class I cavity (human tooth 17). The tooth was fixed on a force gauge for simultaneous determination of application forces with varying storage (6/25°C) and application temperatures (6/25°C). On basis of these data tensile tests were performed with a dental plugger (application force 1N/2N; v=35 mm/min) on PMMA- or human tooth plates. Composite was dosed onto the tip of the plugger and applied. Application and unplugging was performed once and unplugging forces (UF) and length of the adhesive flags (LAF) were determined at different storage (6/25°C) and application temperatures (25/37°C). Unplugging work (UW) was calculated from area of UF and LAF data. The individual assessment revealed significantly different temperature-dependent application forces between 0.58 N and 2.23 N. Adaptability was assessed between 2.1 and 2.8 school scores. Stickiness varied significantly between the materials (scores: 2-3.2). UW differed significantly between the materials with values between 3.20 N mm and 37.83 N mm. Between PMMA substrate or tooth slides and between 1N or 2N application force only small UW differences were found. The presented in vitro unplugging work allows for an in vitro estimation of the handling parameters adaptability and stickiness. Copyright © 2014 Academy of Dental Materials.

    The aim of this study is to look at the efficacy of radiosterilised demineralised freeze dried bovine bone xenograft as a dental haemostatic agent in tooth socket wound following tooth extraction. Six adult Merino sheep underwent extraction of two central incisor teeth under general anaesthesia. In one tooth extraction socket (socket side A) a standard gelatin dental haemostatic agent was inserted while a radiosterilised cancellous bovine bone cube was inserted into the second tooth extraction socket (socket side B). The time taken for the bleeding from the both socket to stop was noted and the sheep were kept asleep under general anesthesia till complete hemostasis was achieved. The feeding habits and wound healing were observed till the tenth postoperative day. Results showed that in socket A, complete hemostasis was achieved in a mean time of 135 seconds (range 110 seconds to 145 seconds) and in socket B, complete hemostasis was achieved in a mean time of 97 seconds (range 8 8 seconds to 112 seconds). Observation regarding feeding habits demonstrate that all the sheep showed preference to chew food on the side of socket 'side B' till the fifth postoperative day and by the seventh day, all sheep chew on both sides of the jaw. The standard gelatin dental hemostatic agent was found to be dislodged from all socket side B on the first postoperative day while the bovine bone cube remained in socked side A till the seventh postoperative day. In conclusion, radiosterilised cancellous bovine bone cube may be applied as an effective dental hemostatic agent following tooth extraction
