    This his article reports the findings of a study conducted to investigate the personality types of Chinese dental school applicants. The Chinese version of the Myers-Briggs Type Indicator (MBTI) (Form G) was used to assess the personality styles of 332 dental school applicants from the mainland of China. The results of the MBTI for Chinese dental school applicants were compared with a previous study of applicants from the U.K. A higher percentage of this group of Chinese applicants scored higher for Introversion (I) than Extroversion (E); both Chinese and English applicants preferred Judging (J) to Perceiving (P). The dominant personality types in Chinese applicants were ISTJ, ESTJ, and ISFP. The findings suggest that the personality types of Chinese dental students may be somewhat different from the personality profiles exhibited by dental students from other nations. The findings may be of value to individuals who desire to investigate personality type differences among dental students with different cultural backgrounds.

    Recent dental school surveys have indicated a slight decrease in the overall number of dental school applicants. As a result, competition for the most highly qualified students is increasing among dental schools. A number of factors may contribute to an applicant's decision on where to matriculate, such as tuition costs, cost of living in an area, location of the dental school, reputation, availability of financial aid, and the school's facilities. Identifying the reasons why students choose to attend a specific school may be an important first step in formulating a strategic plan for recruitment. As a result, a survey was sent to all students (250) interviewed at the University of Pittsburgh School of Dental Medicine for the 2000-01 admissions cycle. The results of this survey were compared to a similar survey sent following the 1994-95 admissions cycle. In addition, the results of the University of Pittsburgh surveys were compared to a similar survey conducted by a different northeastern dental school. The factors rated most important in 1994-95 were reputation, facilities, and location, in order. In 2000-01, location, curriculum, tuition, and reputation were rated the most important factors, in order. This information may assist admissions officers in formulating an effective recruitment strategy for the most highly qualified applicants.

    The purpose of this study was to examine what cognitive and non-cognitive factors were responsible for predicting the academic performance of dental students in a dental school in the Republic of Korea. This school is one of those in Korea that now require applicants to have a bachelor's degree. In terms of cognitive factors, students' undergraduate grade point average (GPA) and Dental Education Eligibility Test (DEET) scores were used, while surveys were conducted to evaluate four non-cognitive measures: locus of control, self-esteem, self-directed learning, and interpersonal skills. A total of 353 students matriculating at Seoul National University School of Dentistry in 2005, 2006, 2007, and 2008 consented to the collection of records and completed the surveys. The main finding was that applicants who scored higher on internal locus of control and self-efficacy were more likely to be academically successful dental students. Self-directed learning was significantly associated with students ranked in the top 50 percent in cumulative GPA. However, students' interpersonal skills were negatively related to their academic performance. In particular, students' lack of achievement could be predicted by monitoring their first-year GPA. Therefore, the identification of those factors to predict dental school performance has implications for the dental curriculum and effective pedagogy in dental education.

    The increasing complexity of many restorative procedures often involves articulation of study and working casts to ensure accurate fabrication of restorations. Correct selection and use of articulators can be crucial to successful restoration. The aim of this paper is to determine which articulators are recommended for various restorative procedures in UK dental schools, for use by undergraduate students. A questionnaire-based study of all UK dental schools was carried out, with a 100% response rate. Recommended articulator application for specified procedures was established from the literature and questionnaire results were compared with this. The results indicated that dental schools in the UK generally teach appropriate articulator use for most procedures. However, there are some limited areas of what may be argued to be inappropriate recommendation in some establishments.

    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.

    Our objective was to evaluate whether there is an association with the different levels of dental fluorosis and the presence of dental trauma amongst school children. A transversal study was conducted amongst school children from the age of 12. Dental examinations were conducted by 24 well trained and fully qualified dental surgeons. Data was collected from 36 randomly selected public schools amongst 89 schools in a municipality. The criteria used to diagnose dental fluorosis was based on the Dean's fluorosis Index and for diagnosing dental trauma we looked for clinical signs of crown fractures and dental avulsions. Multiple descriptive analysis, which was bivariate, was carried out. Amongst the 2,755 school children that took part in the study 1,089 (39.6%) were diagnosed with dental fluorosis and 106 (3.8%) had one tooth or more with dental trauma. We noted a high prevalence of dental fluorosis, independent of the level of severity, amongst individuals with one tooth or more who had dental trauma. This association was even more evident where there were severely high levels of fluorosis. We also noted that the presence of fluorosis was greater amongst those that actively paid more attention to discoloration on their teeth and who received treatment from a dental professional at their schools. Nevertheless dental fluorosis was associated with the presence of dental trauma, independent of its severity.

  11. Emerging Dental Applications of Raman Spectroscopy

    Science.gov (United States)

    Choo-Smith, Lin-P'ing; Hewko, Mark; Sowa, Michael G.

    Until recently, the application of Raman spectroscopy to investigate dental tissues has primarily focused on using microspectroscopy to characterize dentin and enamel structures as well as to understand the adhesive interface of various resin and bonding agents used in restorative procedures. With the advent of improved laser, imaging/mapping and fibre optic technologies, the applications have expanded to investigate various biomedical problems ranging from oral cancer, bacterial identification and early dental caries detection. The overall aim of these applications is to develop Raman spectroscopy into a tool for use in the dental clinic. This chapter presents the recent dental applications of Raman spectroscopy as well as discusses the potential, strengths and limitations of the technology in comparison with alternative techniques. In addition, a discussion and rationale about combining Raman spectroscopy with other optical techniques will be included.

    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.

  15. Holography And Holometry Applications In Dental Research

    Willenborg, George C.

    1987-06-01

    The earliest reference to holographic applications appeared in the dental literature in 1972 when Wictorin, Bjelkhagen and Abramson described a method to study elastic deformation of defective gold solder joints in simulated fixed bridges. Their paper, published in the Swedish dental literature, offered a concise presentation of the interferometry technique which led to the development of other research applications of holographic interferometry(holometry) in dentistry. In this presentation, the development and application of the interferometry technique in the dental field will be discussed. Various interesting and potentially useful applications of holography have appeared in the dental literature over the past decade. Some of these, which will be discussed, include the use of holograms as a storage medium for dental study models, multiplexing of computer(CT) scan sections to form white light viewable holograms and the potential application of holographic training aids in the teaching of the basic courses of dental anatomy and restorative dentistry. In addition, some unique related applications will be mentioned including a laser reflection method for accurate non-contact measurement of tooth mobility/movement and a technique for contour mapping of occlusal surfaces to measure wear of restorative materials.

    2009-05-01

    There is a wealth of evidence to indicate that if dental caries can be recognized at an early stage, it is possible to halt its progression or even reverse it. This has led to an increased interest in the development of diagnostic techniques capable of visualizing caries at an early stage in addition to providing clinicians with an aid to diagnosis. Several techniques are available for research and clinical applications for detecting early demineralization. This manuscript has reviewed some of the techniques currently available to determine their advantages, whether they have any limitations and their applicability to dental research and clinical dentistry. Not one method is the perfect choice in all situations, but what is clear is that the development and application of biophysical technologies have allowed major advances to be made in dental research as well as in clinical dentistry. With continued developments these technologies will play an important role in the future management of dental disease.

    2012-02-01

    To investigate aspects of the teaching of restoration repair as a minimally invasive alternative to the replacement of defective direct composite restorations in teaching programmes in undergraduate curricula in dental schools in the United Kingdom and Ireland. An online questionnaire which sought information in relation to the current teaching of composite restoration repair was developed and distributed to the 17 established UK and Irish dental schools with undergraduate teaching programmes in Spring 2010. Completed responses were received from all 17 schools (response rate= 100%). Fifteen schools reported that they included teaching of repair techniques for defective direct composite restorations in their programme. Of the two remaining schools, one indicated that it would introduce teaching of repair techniques during the next five years. The most common indication for a composite repair was that of 'tooth substance preservation' (15 schools). The defects in restorations considered appropriate for repair rather than replacement by the largest number of schools included partial loss of restoration (13 schools) and marginal defects (12 schools). The most commonly taught surface treatment when performing a repair was mechanical roughening of the existing composite with removal of the surface layer (14 schools). Thirteen schools taught etching and the application of an adhesive bonding agent to the prepared surfaces, while the most commonly taught material for completing the repair was a hybrid composite resin (12 schools). Popular finishing implements included diamond finishing instruments (13 schools) and finishing discs (11 schools). Not withstanding reluctance amongst general dental practitioners, the teaching of repair of a defective composite restoration, rather than total restoration replacement, is firmly established within UK and Irish dental school programmes. Repair techniques have clear advantages for patients, not least including a minimally invasive

    To evaluate the state and level of pre-clinical endodontic education in German dental schools and to evaluate differences with regard to intensity and extent of teaching, time devoted to teaching pre-clinical endodontics, personnel resources in teaching and technical equipment. Twenty-eight questionnaires were e-mailed to those in charge of pre-clinical endodontic education in German dental schools. The extent of education, the student-teacher ratio, the teaching content as well as the application of teaching materials and technologies were asked. If, after 4 weeks, no response had been received, the questionnaire was sent out by e-mail again. In the absence of a reply, a phone call was made to the corresponding university to conduct the survey by phone. With feedback from 27 of 28 dental schools, the response rate was 96%. Pre-clinical endodontic education at German universities varied considerably. Theory classes ranged from 5 to 30 h (13.3 h mean), practical classes from 12.5 to 60 h (45.4 h mean). The student to staff ratio varied between 9 : 1 and 30 : 1 (16 : 1 mean). Forty-eight per cent of the universities had a specialist in endodontics or a teacher with a special interest. A dental microscope was available for pre-clinical teaching purposes in 38% of the universities. The majority (63%) of universities taught root canal preparation with rotary nickel titanium instruments. Pre-clinical endodontic education varied considerably between German universities because of differences in programme design, staff and course content.

    Increasing the quality of the services provided in a Dental School can raise the satisfaction level of patients and consequently increase the level of their oral health. This study was conducted to evaluate the quality of dental care and services provided to patients referred to a Dental School in Kerman, Iran. In this qualitative study, face-to-face, in-depth interviews were conducted with 41 participants [25 patients (P), 5 nurses (N), 6 dental academic staff (AS), and 5 dental students (S)]. Then, the interviews were transcribed and analyzed, using content analysis of data. Data analysis in qualitative research involves breaking down the data and searching for codes and categories that are then reassembled to form themes. Both positive and negative themes emerged. Positive themes included: good infection control, service accessibility, patient appointments and visits were not assigned on merit, precise examinations, and comprehensive treatment plans. Negative themes included: long wait time, lack of options to pass waiting time, such as newspapers and television, an insufficient number of nurses, and not enough professors for supervision. In addition, the results of this study show that the patients and dental staff have high expectations in relation to dental services, and that implementation of these expectations would increase the overall satisfaction with and the quality of the level of services. Finally, some recommendations for improving services in the Kerman Dental School were given to the managing team of the Dental School.

    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 Introduction: The concepts about dental caries and periodontal diseases are learned at dental schools may directly influence the conduct of the future dentists regarding the control and treatment of these diseases. Aim: To assess the variation in the understanding of the concepts of dental caries and periodontal diseases among first to final year undergraduate dental students. Materials and Methods: A cross-sectional, questionnaire-based study was conducted among 400 students pursuing their graduation in a private dental college situated in Sri Ganganagar city, Rajasthan, India. Descriptive analysis was done, and Chi-square test with a significance level of 5% was done to compare the frequency based data. Results: For concepts related to dental caries, the 1st year students' response showed shift toward biological concept, which was also present for the 2nd year but the 3rd year onwards the majority of students cited the comprehensive multi-factorial concept (P = 0.0002. Final year students were more knowledgeable than the 1st, 2nd, and 3rd year students regarding gingival bleeding, swelling, redness, and bad breath being the most important signs of periodontal disease (P = 0.004. Conclusion: Significant variation in the school of thoughts and limited knowledge regarding the concepts of common dental diseases among dental undergraduate students is seen. There might be a need to reform the initial concept building methods utilized in dental institutions to improve the basic knowledge of undergraduate students of the common dental diseases.

    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.

    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.

    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.

Standard tests of bivariate association and multivariate regression models appropriate for continuous and discrete dependent variables were used to examine the relationship between multiple indicators of admission criteria and dental school performance for six recent classes at the University of Florida College of Dentistry (UFCD). The admission criteria included the undergraduate science grade point average (GPA), undergraduate non-science GPA, Dental Admissions Test (DAT) academic score, Perceptual Motor Aptitude Test (PMAT) score, and admission interview score. Measures of dental school performance were the National Dental Board Examination Part I and Part II (NB-I, NB-II) scores, yearly and final dental school GPA, and academic progress through the UFCD program. In general, most admission criteria were good bivariate indicators of dental school performance. Multivariate analyses indicated that students with higher undergraduate science GPAs and DAT academic scores were more likely to achieve higher NB-I and NB-II scores. The undergraduate science GPA and admission interview score were the most consistent determinants of dental school GPA. Students with lower undergraduate science GPAs, DAT academic scores, and PMAT scores were more likely to remediate, to repeat an academic year, or to be dismissed. Although bivariate differences were observed in several admission criteria of students who remediated one or more courses, repeated an academic year, or were dismissed only the undergraduate science GPA and the PMAT score were indicators of programmatic progress in the multivariate analysis.

    Preprofessional students' grade point averages (GPAs) and aptitude test scores have been moderately successful in predicting student performance in dental school. The authors attempted to improve the predictability of the school's admission process by combining several preprofessional academic averages and selected nongraded personal attributes into a single Admission Index (AI) score. A Pearson r of 0.67 was found for the relationship between the AI and first-year dental school GPA for University of Louisville dental students accepted into the class of 1984. The correlation coefficient generated from the AI and first-year dental school GPA was markedly superior to those generated by any single predictor. The authors propose that the AI is of value not only for its use in the admission process, but also in the development of an interceptive student monitoring program for the less-qualified student.

    Accreditation of US dental schools requires a formal system of quality assessment of clinical adverse events (AE). There is no universal system to collect, record, interpret, or release findings or trends pertaining to AEs. The objective of this study was to compare similarities and differences among the AE reporting forms used at US dental schools. Sixteen (24%) dental schools responded to a query to provide copies of their AE forms. The forms were analyzed to identify unique AE items. A total of 69 unique AE items were identified, grouped, and ranked according to frequency. Methods of AE data collection were also noted. The forms were different in organization, form, and content. The 69 AE items represented a wide variety of information, with no standardization of the type of information, how it was collected, or by whom. We identified 9 most requested AE items and 4 least requested AE items. The schools differed in how the information was obtained: 2 schools used a menu, 8 schools used free response, and 6 schools used a hybrid of both methods. We found that dental school clinic AE reporting forms are not standardized in structure, organization, or content. We conclude that a hybrid form containing both guided responses and free responses would ensure that proper information is being reported to fully understand why/how an AE occurred. In addition, dental schools need to develop a standardized method of collecting and assessing AE data which will allow for quality improvement and increased patient safety.

    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.

    The United Kingdom's Clinical Aptitude Test (UKCAT) aims to assess candidates' "natural talent" for dentistry. The aim of this study was to determine the validity of the UKCAT for dental school applicant selection. The relationship of the UKCAT with demographic and academic variables was examined, assessing if the likelihood of being offered a place at a UK dental school was predicted by demographic factors and academic selection tools (predicted grades and existing school results). Finally, the validity of these selection tools in predicting first-year dental exam performance was assessed. Correlational and regression analyses showed that females and poorer students were more likely to have lower UKCAT scores. Gender and social class did not, however, predict first-year dental exam performance. UKCAT scores predicted the likelihood of the candidate being offered a place in the dental course; however, they did not predict exam performance during the first year of the course. Indeed, the only predictor of dental exam performance was existing school results. These findings argue against the use of the UKCAT as the sole determinant in dental applicant selection, instead highlighting the value of using existing school results.

    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 aim of the study was to assess the prevalence of dental fluorosis, dental caries, and associated risk factors in the school children of district Fatehgarh Sahib, Punjab, India, using a cross-sectional study design. Oral health status of children aged between 8 and 15 years was assessed using World Health Organization (WHO) 2013 criteria. Dental fluorosis was assessed using Dean's index, and dental caries were recorded using decayed, missing, filled/decayed, extracted, filled (DMF/def) indices. Four hundred school children were examined, of which 207 were in the 8-11-year-old group and 193 were in the 12-15-year-old group. The overall prevalence of dental fluorosis was 4.1%, which might be linked to a high concentration of fluoride in drinking water at certain locations of rural Punjab. The prevalence of dental caries was 36.5% with a mean DMF score of 0.3 and def score of 0.6. Risk factors for dental caries include oral hygiene behavior and sugar consumption patterns. The study highlights the need to increase awareness about the oral health and hygiene among the school children in India.

    This study compared the dental curricula at dental schools in China and Japan. A survey was conducted in representative dental schools in China and Japan. It was found that, in China and Japan where dental schools recruit students directly from high schools, more attention is paid to introduction of early professional education. Most dental schools in Japan arrange dental subjects for their students from the first through the fourth years, while in China, only a few dental schools take this path although many of them are currently making changes. It was also discovered that, in both countries, an increasing number of dental schools assign a specific dental subject to the same period with its relevant bioscience or biomedical counterparts, which makes it possible for them to enhance each other reciprocally in a positive way for students and consequently help dental students master the related topics.

    Full Text Available "nBackground and Aim: In recent decades many guidelines has been conducted by radiation protection organizations about radiation protection in dentistry. This study was designed to evaluate the observance of these guidelines in educational clinics of all dental schools in Iran."nMaterials and Methods: In this cross-sectional study a questionnaire based on National Radiation Protection guidelines was conducted. The questionnaire consisted of questions about radiation protection principles in dental radiography that is needed for patients and personnel protection and quality control of radiological instruments. The questionnaires were completed by the responsible person of each radiology department of dental schools (18 schools. After gathering the data, the results were compared with radiation protection standards."nResults: There was proper condition in the case of the existence of radiation protection facilities, such as lead apron, thyroid shield and lead impacted walls. However, personnel rarely use these facilities. Usage of high speed films and existence of automatic processor in dental schools was an appreciable point. The main problem was related to the lack of regular quality control programs."nConclusion: The observance of radiation protection regulations in radiology departments of dental schools was proper. But majority of departments had no regular quality control programs; and the use of digital systems in dental radiography was not common.

    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.

    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; pLGBT orientations, the more they agreed that persons can feel comfortable regardless of their sexual orientation (r=.585; pLGBT backgrounds and that staff, faculty, students, and patients from these backgrounds are not discriminated against.

    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. An online questionnaire which sought information in relation to the current teaching of posterior composites was developed and distributed to the 17 established Irish and UK dental schools with undergraduate teaching programmes in late 2009. Completed responses were received from all 17 schools (response rate = 100%). All 17 schools taught the placement of occlusal and two-surface occlusoproximal composites in premolar and permanent molar teeth. Two schools did not teach placement of three-surface occlusoproximal composites in either premolars or molars. In their preclinical courses, ten schools taught posterior composites before teaching dental amalgams. Fifty-five percent of posterior restorations placed by dental students were of composite (range = 10-90%) and 44% amalgam (range = 10-90%), indicating an increase of 180% in the numbers of posterior composites placed over the past five years. Diversity was noted in the teaching of clinical techniques and students at different schools are trained with different composites and bonding systems. Some cause for concern was noted in the teaching of certain techniques that were not in keeping with existing best evidence, such as the teaching of transparent matrix bands and light

    Chinese dental education is organized and controlled by the government at different levels, and the curriculum is based on the stomatology model. The unique feature of this system has been a heavy emphasis on the medical sciences and the integration of medicine with dentistry. However, the problems with this curriculum have been greater than its advantages since a dental student trained under this educational model was unlikely to be well prepared for patient care in a clinical setting and could struggle to apply modern techniques during his or her professional career. From 1995 to 2000, six well-known Chinese dental schools participated in a curriculum innovation project supported by the central government. This article describes the educational model developed during the project and presents several new educational concepts that have been put into practice in dental schools in China. Nevertheless, the new model is not without problems. If there are no additional innovations related to didactic teaching methods, clinical education, and interpersonal skills, the outcome of recent changes in the curriculum of Chinese dental schools will be unpredictable, and our dental education will not continue to advance.

    Full Text Available Dental caries is a major cause of tooth loss in children and young adults. Dental caries have been linked to the situation of underprivileged families, nutritional imbalance, and poor oral hygiene techniques, including lack of tooth brushing or flossing the teeth, and also have a genetic etiology. Dietary habits and dental hygiene practice can result in high caries in school children. This research aimed to reveal the correlation between dietary habits and dental hygiene practice with dental caries among school children in urban area of Semarang. The subjects of this research are the elementary student 7 – 9 years old enrolled in schools located in at urban area in Semarang in 2016 and the mother of a student who became the study sample. Data were statisically analyzed usingbivariate analysis and multivariate analysis. Based on the research result, it can be concluded that: there was no correlation between total carbohydrate intake, refined carbohydrate intake, fiber intake, dental hygiene practice with dental caries, bottle feeding and duration of bottle feeding were assosiated with dental cariest-score.

    Full Text Available OBJECTIVE: Sexual harassment is unlawful in all work and educational environments in most nations of the world. The goals of this study were to describe the sexual harassment prevalence and to evaluate the experiences and attitudes of undergraduate students in one dental school in Brazil. MATERIAL AND METHODS: An 18-item questionnaire was administered to 254 dental students with a completion rate of 82% (208. Students were requested to respond to questions about their background and academic level in dental school, their personal experiences with sexual harassment and their observation of someone else being sexually harassed. 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.

    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. Results of the survey show a majority of the PASS students feel that they are part of the school and that there is someone in the school whom they can approach for problems.

    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.

    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.

    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.

    During the inaugural year (2006-07) of the Academic Dental Careers Fellowship Program (ADCFP), 110 faculty members at ten different dental schools were interviewed by dental students who were participating as ADCFP fellows in this year-long program designed to introduce them to faculty roles and activities and help them gain an appreciation for the rewards and issues associated with academic life. The goals, format, and components of the ADCFP are described in a companion article in this issue of the Journal of Dental Education. One of the fellows' assignments during the ADCFP was to interview faculty at various academic ranks who had differing degrees of work emphasis in teaching, research, service/patient care, and administration. Sixty-nine (63 percent of the total) of these interviews were reviewed and analyzed by the authors, who were student fellows in the ADCFP during 2006-07. The purpose of these interviews was to provide the fellows with insight into the positive aspects and challenges in becoming and remaining a dental school faculty member. This aggregate perspective of the interviews conducted at ten dental schools highlights the motivations and challenges that confront a dentist during the process of choosing a career in academic dentistry and determining if dental education is a good fit for each individual who elects to pursue this pathway. Thematic analysis of the interviews revealed several factors consistently identified by faculty across the schools as being positive influences on the quality of the academic work environment and career satisfaction: mentorship and student interaction, opportunities for scholarship (research and discovery), job diversity, intellectual challenge, satisfaction with the nature of academic work, lifestyle/family compatibility, flexibility, lifelong learning, professional duty, and lab responsibility. A series of negative themes were also consistently identified: bureaucracy/administrative burdens and barriers, time

    This study sought to determine whether using the Myers-Briggs Type Indicator (MBTI) would detect differences in personality preferences in first-year dental students admitted to the same dental school through different admission methods. First-year dental students admitted in 2000 and 2001 were given the MBTI instrument during orientation prior to the start of classes. In fall 2000, the Class of 2004 had 140 students, with 116 in the traditional track and twenty-four in the parallel problem-based learning (PBL) track. In fall 2001, the Class of 2005 had 144 students, all enrolled in the PBL curriculum. All students admitted to the PBL track had experienced a process that included evaluation of their participation in a small group. Students in the traditional track had individual interviews with faculty members. Both student groups were required to meet the same baseline grade point average and Dental Admission Test standards. In 2000, the PBL students showed personality preferences that were distinctly different from the personality preferences of traditional track students in the categories of Extroversion (89 percent PBL, 44 percent traditional) and Thinking (72 percent PBL, 39 percent traditional). In 2001, the all-PBL class retained the trend towards Extroversion (69 percent). This study suggests that admission method may effectively change the personality preference distribution exhibited by the students who are admitted to dental school.

    Full Text Available Introduction and objective: This study aimed to assess the prevalence and severity of dental fluorosis in a group of school children in the city of Campo do Tenente (Parana, Brazil in order to compare the mean fluoride concentration in public water supply and discuss the effective values for fluoridation of water supply, as well as, the need of control of fluoride concentration within the water consumed by population. Material and methods: Firstly, 362 children enrolled in regular public schools, at elementary level, were examined by a single researcher, previously calibrated for Dean’s index application. From these, 90 children were affected by some degree of fluorosis, but only 40 returned the signed free and clarified consent form for participating in the research. Results: It was found that 42.5% of the children presented mild fluorosis and 32.5% moderate fluorosis. Moreover, it was observed that the average fluoride concentration in public water supply, in 2004, was 1.7 ppm of fluoride. Conclusion: These results demonstrate the need of a closer supervision of the city situation, by the inclusion of fluoridation external control and constant monitoring of the oral health status of the population.

    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

    2013-01-01

    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.

    The teaching of posterior composites has undergone considerable refinement and development in western countries in recent years. However, little information exists on this teaching in other parts of the world. The aim of this paper is to investigate the teaching of posterior composites to undergraduate dental students in Japan. In late 2007/early 2008, a questionnaire seeking information on the teaching of posterior composites was distributed by email to the person responsible for teaching operative dentistry in each of the 29 dental schools having undergraduate dental degree programmes in Japan. Twenty-three completed responses were returned (response rate = 79%). While all 23 schools taught the placement of composite in occlusal cavities in premolars and molars, 7 schools did not teach the placement of two-surface occlusoproximal composites in premolars (n = 1) and molars (n = 6) and 14 schools and 15 schools do not teach placement of three surface occlusoproximal composites in premolars and molars, respectively. While composite at the time of the survey accounted for 45% of posterior direct restorations placed by students, it is anticipated that this proportion will increase to 59% in 5 years time. Variations were noted between schools in the teaching of principles of cavity design, techniques for restoring proximal contours and light-curing technologies; however, more consistency was observed in techniques used for protecting operatively exposed dentine than that observed in western countries. Despite variations between dental schools being noted in the teaching of certain techniques for posterior composites, the overall extent and content of teaching of posterior composites in Japan could be described as comparable, if not exceeding, than that observed in western countries.

    The aims of this study were to determine the prevalence and nature of international volunteer programs for predoctoral students at U.S. dental schools and to document the change over five years. Web-based surveys were conducted in 2009 and 2016. An invitation to participate in the study, along with a hyperlink to the survey, was emailed to the deans of all U.S. dental schools in the two years. In 2009, 47 of 58 dental school deans responded to the survey, for a response rate of 81%. In 2016, 48 of 64 dental school deans responded, for a response rate of 75%. From 2009 to 2016, the number of schools reporting dental student international experiences increased from 25 to 31. In 2016, 65% of responding schools offered dental student international experiences, an 11.5% increase over the results of the 2009 survey. Concomitantly, the number of deans reporting their students' participation in international opportunities not officially sanctioned by the school decreased from 41 to 34. These findings showed an increase in the number of dental schools providing international experiences for their students and established baseline data to assess trends in the future.

    2016-12-01

    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.

    Evidence of violations of academic integrity can be identified at all levels of education. A survey on academic integrity was mailed in 1998 to the academic deans of all fifty-five U.S. dental schools, with a response rate of 84 percent. This survey showed that reported incidents of academic dishonesty occur in most dental schools, with the average school dealing with one or two cases a year. The most common incidents of dishonest behavior involved copying or aiding another student during a written examinations; the second most common involved writing an untrue patient record entry or signing a faculty member's name in a patient chart. Respondents indicated the major reason for failure to report academic dishonesty was fear of involvement because of time and procedural hassles and fear of repercussions from students and peers.

    2014-10-01

    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.

    This document was written by Task Force 3 of DentEd III, which is a European Union funded Thematic Network working under the auspices of the Association for Dental Education in Europe (ADEE). It provides a guide to assist in the harmonisation of Dental Education Quality Assurance (QA) systems across the European Higher Education Area (EHEA). There is reference to the work, thus far, of DentEd, DentEd Evolves, DentEd III and the ADEE as they strive to assist the convergence of standards in dental education; obviously QA and benchmarking has an important part to play in the European HE response to the Bologna Process. Definitions of Quality, Quality Assurance, Quality Management and Quality Improvement are given and put into the context of dental education. The possible process and framework for Quality Assurance are outlined and some basic guidelines/recommendations suggested. It is recognised that Quality Assurance in Dental Schools has to co-exist as part of established Quality Assurance systems within faculties and universities, and that Schools also may have to comply with existing local or national systems. Perhaps of greatest importance are the 14 'requirements' for the Quality Assurance of Dental Education in Europe. These, together with the document and its appendices, were unanimously supported by the ADEE at its General Assembly in 2006. As there must be more than one road to achieve a convergence or harmonisation standard, a number of appendices are made available on the ADEE website. These provide a series of 'toolkits' from which schools can 'pick and choose' to assist them in developing QA systems appropriate to their own environment. Validated contributions and examples continue to be most welcome from all members of the European dental community for inclusion at this website. It is realised that not all schools will be able to achieve all of these requirements immediately, by definition, successful harmonisation is a process that will take time. At

    The bonding restoration has become an important clinical technique for the development of dental bonding technology. Because of its easy operation and the maximum preservation of tooth tissues, bonding repair is widely used in dental restoration. The recent multi-mode universal adhesives have brought new progress in dental bonding restoration. In this article the universal adhesives were reviewed according to its definition, development, improvement, application features and possible problems.

    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.

    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.

    2014-11-01

    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 (pservice providers were a driver of retention. The resulting insights benefit dental schools in recruiting patients with the greatest likelihood of returning for care, providing dental students with skills 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.

    Since the year 2000, prospective dental students at Innsbruck Medical University, Innsbruck, Austria, have undergone both theoretical and practical preadmission exams, called the Dental Admission Test (DAT). The aim of this investigation was to assess the suitability and outcome of this selection practice. Five classes from 2001 to 2005 (N=97; forty-three female, fifty-four male) were retrospectively reviewed. DAT results were compared with student performance, gender, ability to graduate on time, and dropout rates. Furthermore, the influence of a previous medical degree was evaluated. The t-test was used to analyze correlations between the results of the DAT and the following: gender, students who graduated on time, and students who had previously completed a medical degree. Pearson's correlation coefficient (r) was applied to analyze correlations among test scores, age, and students' performance during the first clinical year. Students graduating on time were noted to have significantly better DAT results; students with a previous medical degree showed significantly better grades during their first clinical year. The difference between the performance of male and female applicants on the DAT was not significant. Correlation was found between DAT results and dental school performance (r=-0.462). We conclude that the DAT may reduce dropout rates by excluding applicants unlikely to be successful in practical courses and that DAT scores are a reliable tool to predict student performance during the first clinical year of dental school in Innsbruck.

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.

    Chitosan is a linear amino-polysaccharide and a natural polymer with a structure based on repetitive deacetylated and acetylated units randomly distributed. It is produced from chitin, one of the most common naturally occurring polysaccharides. Its numerous biomedical applications have been extensively described in the literature. It becomes more and more popular as a therapeutic agent and its use is constantly extended. Given its commonness, regenerative properties, easy chemical treatment, and biocompatibility, it might be used in the treatment of damaged oral cavity tissues. Due to its antimicrobial and regenerative-inducting properties as well as high biocompetency, chitosan is more and more frequently used in medicine and dentistry. It can be applied in all fields of dentistry including preventive dentistry, conservative dentistry, endodontics, surgery, periodontology, prosthodontics and orthodontics. Several data discussing the effectiveness of chitosan use on new bone formation are still inconclusive. The aim of the paper was to evaluate the applicability and biochemical impact of chitosan on oral health maintenance. Even though chitosan might find its adhibition in all dental specialities, it should still be considered as a potential allergen and thus further studies on this topic should be carried out.

    The present study aimed to examine the impact of "curricula for undergraduate education in oriental medicine (OM)/complementary and alternative medicine (CAM)" on student awareness of OM. A questionnaire survey was conducted involving the Nagasaki University School of Dentistry (NUSD), a university that implements education in OM as part of its undergraduate curriculum, and Tokyo Dental College (TDC), which does not teach OM. The third- and fifth-year students of both NUSD and TDC underwent the anonymous questionnaire survey, which included questions regarding their knowledge of OM and CAM, interests in these subjects, and their opinions on the necessity of teaching OM in the undergraduate dental education, and the results were collected for analysis. Whereas 33% of 5(th) year NUSD students had knowledge of OM/CAM was 33%, only 10% of 5(th) year TDC students reported knowledge on the subject. 69% of 5(th) year NUSD students interested in OM/CAM, while 5(th) year TDC students who interest them were only 45%. Although 77% of 5(th) year NUSD students were in favor of OM education implemented in the Faculty of Dentistry, the percentages of TDC students of that were smaller (46% in 3(rd) year and 48% in 5(th) year). Whereas 26% of 5(th) year TDC students did not recognize the necessity of oriental medicine education, only one 5(th) year NUSD student (2%) did not so. Introduction of education in OM in the undergraduate dental education program helps students to increase their interests in dental clinical applications.

    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 Myers-Briggs Type Indicator (MBTI) was administered to 256 dental students, representing four classes, at the University of Florida College of Dentistry. The results of this psychological instrument were then correlated with overall dental school performance based on results from the National Dental Board Examinations Part I and II (NB-I, NB-II), yearly class rank, and specific academic difficulties as measured by the Student Performance Evaluation Committee. Introverted students were found to display a significantly increased performance on NB-I (p = .038) and NB-II (p = .044). They were also found, however, to demonstrate a progressively lower class rank over the four-year period than extroverted students and were more likely to experience major academic difficulties as well. Judging and sensing individuals were found to earn a higher class rank over the four-year period than perceiving and intuitive students, respectively. Perceiving students were found to exhibit major difficulties or were placed on probation more often than judging individuals. These results may prove useful in counseling students to recognize potential problems before they commence their dental education or to anticipate and address specific weaknesses during the course of their education.

    The use of virtual patients in dental education is gaining acceptance as an adjunctive method to live patient interactions for training dental students. The objective of this study was to determine the extent to which virtual patients are being utilized in dental education by conducting a survey that was sent to sixty-seven dental schools in the United States and Canada. A total of thirty dental schools responded to the web-based survey. Sixty-three percent of the responding dental schools use virtual patients for preclinical or clinical exercises. Of this group, 31.3 percent have used virtual patients in their curricula for more than ten years, and approximately one-third of those who do use virtual patients expose their students to more than ten virtual patient experiences over the entirety of their programs. Of the schools that responded, 90.5 percent rated the use of virtual patients in dental education as important or very important. An additional question addressed the utilization of interactive elements for the virtual patient. Use of virtual patients can provide an excellent method for learning and honing patient interviewing skills, medical history taking, recordkeeping, and patient treatment planning. Through the use of virtual patient interactive audio/video elements, the student can experience interaction with his or her virtual patients during a more realistic simulation encounter.

  19. Potential of Electrospun Nanofibers for Biomedical and Dental Applications

    2016-01-01

    Full Text Available Electrospinning is a versatile technique that has gained popularity for various biomedical applications in recent years. Electrospinning is being used for fabricating nanofibers for various biomedical and dental applications such as tooth regeneration, wound healing and prevention of dental caries. Electrospun materials have the benefits of unique properties for instance, high surface area to volume ratio, enhanced cellular interactions, protein absorption to facilitate binding sites for cell receptors. Extensive research has been conducted to explore the potential of electrospun nanofibers for repair and regeneration of various dental and oral tissues including dental pulp, dentin, periodontal tissues, oral mucosa and skeletal tissues. However, there are a few limitations of electrospinning hindering the progress of these materials to practical or clinical applications. In terms of biomaterials aspects, the better understanding of controlled fabrication, properties and functioning of electrospun materials is required to overcome the limitations. More in vivo studies are definitely required to evaluate the biocompatibility of electrospun scaffolds. Furthermore, mechanical properties of such scaffolds should be enhanced so that they resist mechanical stresses during tissue regeneration applications. The objective of this article is to review the current progress of electrospun nanofibers for biomedical and dental applications. In addition, various aspects of electrospun materials in relation to potential dental applications have been discussed.

    As dental schools continue to seek the most effective ways to provide clinical education for students, it is important to track the effects innovations have on students' clinical experience to allow for quantitative comparisons of various curricula. The aim of this study was to compare the impact of three successive clinical curricula on students' experience at one U.S. dental school. The three were a discipline-based curriculum (DBC), a comprehensive care curriculum (CCC), and a procedural requirement curriculum plus externships (PRCE). Students' clinic experience data from 1992 to 2013 were analyzed for total experience and in five discipline areas. Clinic experience metrics analyzed were patient visits (PVs), relative value units (RVUs), and equivalent amounts (EQAs). A minimum experience threshold (MET) and a high experience threshold (HET) were set at one standard deviation above and below the mean for the DBC years. Students below the MET were designated as low achievers; students above the HET were designated as high achievers. The results showed significant differences among the three curricula in almost all areas of comparison: total PVs, total EQAs, total RVUs, RVUs by discipline, and number of high and low achievers in total clinical experience and by discipline. The comprehensive care approach to clinical education did not negatively impact students' clinical experience and in many cases enhanced it. The addition of externships also enhanced student total clinical experience although more study is needed to determine their effectiveness. The insights provided by this study suggest that the methodology used including the metrics of PVs, EQAs, and RVUs may be helpful for other dental schools in assessing students' clinical experience.

    Calibration in diagnosis and treatment planning is difficult to achieve due to variations that exist in clinical interpretation. To determine if dental faculty members are consistent in teaching how to diagnose and treat periodontal disease, variations among dental students can be evaluated. A previous study reported high variability in diagnoses and treatment plans of periodontal cases at Indiana University School of Dentistry. This study aimed to build on that one by extending the research to two additional schools: Marquette University School of Dentistry and West Virginia University School of Dentistry. Diagnosis and treatment planning by 40 third- and fourth-year dental students were assessed at each of the schools. Students were asked to select the diagnosis and treatment plans on a questionnaire pertaining to 11 cases. Their responses were compared using chi-square tests, and multirater kappa statistics were used to assess agreement between classes and between schools. Logistic regression models were used to evaluate the effects of school, class year, prior experience, and GPA/class rank on correct responses. One case had a statistically significant difference in responses between third- and fourth-year dental students. Kappas for school agreement and class agreement were low. The students from Indiana University had higher diagnosis and treatment agreements than the Marquette University students, and the Marquette students fared better than the West Virginia University students. This study can help restructure future periodontal courses for a better understanding of periodontal diagnosis and treatment planning.

The respondents rated their agreement with eight sentences about what hinder them from producing scientific dental articles based on a 5-grade Likert scale. The data were analyzed usingChi-square test.Results: Totally, 270 filled questionnaires from 14 dental schools were received. Of all respondents, 53% were male, the mean age were 29.6 ± 3.8. About half of the respondents reported at least one published article. Less than half of the respondents reported producing an article from undergraduate thesis; more women than men and more younger than older students (P<0.03. About two-third of the respondents rated absence of an English editing center, no financial incentives, no appropriate environment, and no competency for scientific writing as most prevalent barriers to the production of scientific dental articles.Conclusion: To expand the share of Iran in the production of scientific dental documents, the potential of postgraduate dental students must be regarded and suitable condition for scientific writing must be provided. Specifically, based on the findings of the present study, provision of an English editing facility, establishing financial incentives, and providing the students with appropriate environment and efficient scientific writing education are of utmost importance.

    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.

    2009-09-01

    California is home to one-third of the U.S. population with limited English proficiency (LEP). Studies indicate that treating LEP patients without professional interpreters can result in miscommunication, decreased patient satisfaction, and serious medical errors. To address this problem, federal laws require all health care institutions receiving federal monies to provide interpretation services to their LEP patients at no cost to the patient. In this study we surveyed 122 students and fifty-six faculty members from the five California dental schools with respect to number, communication strategies, impact on education and clinic finances, and student and faculty perceptions regarding serving LEP patients in their clinics. Over 50 percent of students surveyed spoke a foreign language either fluently or moderately fluently. Students reported that about 10 percent of their patients required interpreters, that untrained interpreters (e.g., family, friends, bilingual students) worked adequately, but that LEP patients were more difficult to treat. To comply with federal laws, dental schools are confronted with the challenge of covering the cost of providing language services to LEP patients.

    2017-02-01

    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.

    2012-05-01

    Forensic odontologists play an important role locally and nationally in assisting in the identification of the victims of mass fatality incidents, whether natural or human-made. With the recent passage of legislation by Congress identifying dentists as a first-responder resource, knowledge of their expanding role in disaster response is particularly important. The purpose of this article is to describe the forensic dental course being taught at Creighton University School of Dentistry in Omaha, Nebraska, as a model for providing a fundamental education in forensic dentistry and disaster preparedness at the predoctoral dental level. This model is designed to 1) provide students with a broad view of forensic odontology; 2) give them a functional knowledge of the tools and techniques of the modern forensic dentist; 3) provide basic knowledge of their potential role in disaster preparedness and response; and 4) encourage students to pursue further forensic education, become active in national forensic organizations, and get involved in disaster preparedness/response in their home communities following graduation. This article includes lecture topics, demonstrations, and hands-on exercises being used at Creighton to teach students the fundamentals of forensic odontology and disaster preparedness.

    Full Text Available Aims. To examine the dental treatment needs of inner-city Vancouver elementary school-aged children and relate them to sociodemographic characteristics. Methods. A census sampling comprising 562 children from six out of eight eligible schools was chosen (response rate was 65.4%. Dental treatment needs were assessed based on criteria from the World Health Organization. Results. Every third child examined needed at least one restorative treatment. A higher proportion of children born outside Canada were in need of more extensive dental treatments such as pulp care and extractions compared to the children born in Canada. There were no statistically significant differences in dental treatment needs between age, gender, or income groups or between children with or without dental insurance (Chi Squared P>0.05. The best significant predictors (Linear Multiple Regression, P>0.05 of higher dental treatment needs were being born outside Canada, gender, time of last dental visit, and family income. Having dental insurance did not associate with needing less treatment. Conclusion. A high level of unmet dental treatment needs (32% was found in inner-city Vancouver elementary school-aged children. Children born outside Canada, particularly the ones who recently arrived to Canada, needed more extensive dental treatments than children born in Canada.

    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.

    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.

    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.

    2011-12-01

    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.

    Full Text Available The teaching of posterior composites has undergone considerable assessment and refinement in well-developed countries in recent years. However, little information exists on this teaching in Arab countries. Aim of this study: The aim of this study was to investigate the teaching of direct posterior composite restorations to undergraduate dental students in Kingdom of Saudi Arabia (KSA. Method: An online survey was developed and distributed to 17 Saudi dental schools. The topic of the survey sought information related to current teaching of direct posterior composite restorations in undergraduate teaching programs. Results: Responses were received from 13 schools (response rate = approximately 76%. All respondent dental schools taught the same types of restorations, however there were some variations regarding contraindications of such restorations. In certain dental schools, outdated knowledge was taught related to cavity specifications such as beveling of occlusal margins, the use of clear plastic matrix band and light reflecting wedges. There was shortening of knowledge related to light curing technologies as well as different adhesive systems. Nano-filled dental composite was not taught in approximately half of the respondent schools. Also, the rush into teaching of bulk-fill placement technique was noted. Conclusions: Among Saudi dental schools, there may be some degree of variation in the teaching of posterior composite restorations. Although, some teaching shortcomings were noted, the overall extent and content taught to dental students in KSA may provide enough knowledge that may be essential for preclinical and clinical practice of the direct posterior composite restorations.

    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.

    Full Text Available The purpose of this study was to evaluate the general attitude of senior dental students towards rubber dam use, specifically focusing on endodontic practices prior to starting to serve community. Questionnaires were distributed to senior year students of a private school and a state school in Istanbul. Questions were asked about areas where the students used rubber dam, its advantages and difficulties, and whether they agreed or disagreed with some aspects of the rubber dam. The private school students rated isolation whereas those of the state school selected prevention of aspiration which the top advantage rubber dam provides. Students of the state school agreed with the opinion that isolation cannot be achieved without rubber dam and it extended the procedure with a significantly higher ratio compared to the private school. Within the limitations of the present study, it can be concluded that the perceptions of dental students on rubber dam needs to be improved and strategies should be developed so that this valuable adjunct will comprise one of the indispensable elements of dental care.

    2015-06-26

    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.

    Dental students train in an environment similar to dentists in private practice. The literature reveals that physical and psychosocial stressors in dental schools are associated with adverse health outcomes. While dental educators have provided resources to address psychosocial factors and ergonomics training at the didactic level, the reinforcement of biomechanics at the clinic level has been overlooked. In this article the authors introduce a descriptive analysis of an ergonomics awareness program that expands the ergonomic training by including an assessment of the physical work performed by dental students in the clinic environment.

  7. Controllable Edge Feature Sharpening for Dental Applications

    Directory of Open Access Journals (Sweden)

    Ran Fan

    2014-01-01

    Full Text Available 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 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.

    Lantz, M S; Chaves, J F

    1997-05-01

    Education for the first professional degree in dentistry is intended to produce graduates capable of offering a wide range of high quality dental services to the general public. More than that, it is expected that graduates will be firmly grounded in the scientific basis for their professional practices and be equipped to evaluate critically and integrate selectively new scientific findings that emerge during their professional lifetimes. In addition, they are expected to be able to work effectively with diverse patient populations and to conduct their practices with a high level of sensitivity to the ethical and psychosocial dimensions of patient care. Indiana University School of Dentistry has undergone a process of curriculum reform that has yielded a new first professional degree program. Its hallmarks are large, multidisciplinary courses (seven courses in the first two years) that are taught using a variety of strategies including problem-based learning in small groups as well as lectures. The biomedical sciences curriculum is concept-based. Students will demonstrate their understanding of science concepts and methods by applying them to the solution of research and health care problems. Biomedical sciences will be taught at a level that will provide a comprehensive understanding of the functioning of the human body in health and disease, allow students to assimilate the coming revolution in molecular medicine, and selectively use new diagnostics, preventives, and therapeutics that evolve as molecular biological technologies yield solutions to current medical and dental problems. Using the biomedical sciences curriculum as a vehicle, we will also achieve the goal of training dentists as critical thinkers, problem solvers, lifelong learners, and ethical practitioners, skillful in peer and self-evaluation, and cognizant of the psychosocial as well as biomedical perspective of health and disease.

    Full Text Available Objective: The objective was to find the prevalence of dental fluorosis among school children residing in Kanpur city, Uttar Pradesh India. Materials and Methods: A total of 1343 school children, residing in the city since childhood and consuming the groundwater, in the age group of 7-17 years was selected from various schools. Schools were selected from all four directions of the city. Children were categorized in five age groups and were examined for dental fluorosis. Dean′s criteria for assessment of dental fluorosis were used, and observations were recorded on a study specific performa. Results: Among the 1343 children examined, 243 (18% were found to be having dental fluorosis, among which number of males (131 was more than females (112. Among the different grades of fluorosis observed, mild dental fluorosis was observed in most of the cases (158. It was observed that the southern part of the city had a maximum number of cases of dental fluorosis. Conclusion: It was evident from the results that the city had a good number of cases of dental fluorosis and that the groundwater in certain areas had more than normal quantity of fluoride. Since this study was the first attempt in this area, more studies can be undertaken to substantiate our findings.

    Geriatric dentistry and its instruction are critical in a rapidly ageing population. Japan is the world's fastest-ageing 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 at evaluating 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. Bibliographical data and local information were collected. Descriptive and statistical analyses (Fisher and chi-squared test) were conducted. Japanese dental schools teach geriatric dentistry in 10 geriatric dentistry departments as well as in prosthodontic departments. There were 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 4-year PhD course of study; there is neither a master's degree programme nor a certificate programme 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. 2011 John Wiley & Sons A/S.

  13. Perspectives on the dental school learning environment: theory X, theory Y, and situational leadership applied to dental education.

    2007-08-01

    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.

    Problem-based learning (PBL) is a widely accepted educational method centered on the discussion and learning that emerge from a clinically based problem; however, little has been reported on the details of PBL case-writing in the dental education literature. This article outlines some principles of writing a PBL case as it is practiced at a Chinese dental school and presents, as an example, an actual case based on a clinical problem (ameloblastoma of the jaw) intended to provide a learning focus for predoctoral dental students. A good PBL case should allow for progressive, interdependent actions to be taken in the evaluation and overall management of the patient in context and should trigger inquiry and discussion among students in both the basic sciences (anatomy, physiology, biochemistry, pharmacology, pathophysiology, etc.) and related clinical sciences. The epidemiological, sociological, and ethical considerations related to each problem should also be emphasized as an essential component of effective health care provision.

    If a dental student diagnoses a patient in a dental school clinic as being at high risk of prediabetes or diabetes, the patient should be referred to his or her physician for further diagnostic evaluation, and the physician should send back the evaluation results so that the dental team can optimize treatment and health care choices if the diagnosis is confirmed. The primary aim of this study was to evaluate physicians' responses to written and oral requests for information regarding follow-up diabetes testing. A secondary aim was to evaluate patients' compliance with recommendations to seek medical care after being determined to be at high risk of prediabetes or diabetes in the dental clinic. Based on at least one positive risk factor for diabetes, 74 patients in one U.S. dental school's clinic were screened by third- and fourth-year dental students for prediabetes or diabetes and underwent point of care HbA1C (glycalated hemoglobin) blood tests between June 2014 and June 2015. Patients with an HbA1C value of 5.7% or above were referred to their physicians for follow-up testing. The physician was mailed the patient's HIPAA release and a request for updates to the student regarding the patient's diabetes status. If the physician did not provide the requested information, a dental student telephoned him or her to obtain the patient's diabetes status. Of the 74 patients, 34 (46%) tested positive with HbA1C tests and were referred to their physicians. Of those 34 referred patients, 20 (59%) saw their physicians for additional evaluations within six months of referral. None of the 20 physicians responded to the written requests for information on additional diabetes testing. After one or two telephone requests, all 20 physicians provided the test results. This study found that most of the patients (59%) followed their dental practitioner's advice to seek follow-up care with their physician, supporting the value of conducting these tests in a dental clinic. However, the

    The aim of this article is to investigate the contemporary teaching of the management of defective direct resin composite restorations in dental schools in Japan. A questionnaire relating to the teaching of the management of defective resin composite restorations was developed and e-mailed to 29 dental schools in Japan in 2010. Completed responses were received from 19 of the 29 invited schools (response rate = 66%). Eighteen schools (95%) report that they included the teaching of repair of direct defective resin composite restorations in their dental school programs. Thirteen schools reported that they included both clinical and didactic instruction on the repair of direct resin composite restorations. Fourteen schools did not teach any mechanical roughening of the exposed resin composite restoration surface before undertaking a repair. The most commonly reported treatment was acid etching with phosphoric acid (12 schools). The most commonly taught material for completing repairs was a flowable resin composite (16 schools). The teaching of repair of defective resin composite restorations is well established within many Japanese dental schools, to a greater extent than in some other regions of the world. The impact of this teaching on subsequent clinical practices in Japan should be investigated. Furthermore, it is concluded that there is a need for much stronger leadership in operative and conservative dentistry, ideally at the global level, to resolve differences in key aspects of operative procedures such as repairs.

    The purpose of this study was to gather and analyze information about the status of ethics teaching and learning in U.S. dental schools and to recommend a curriculum development and research agenda for professional ethics in dental education. A survey to collect this information was developed by the authors and administered by the American Society for Dental Ethics. The results suggest that dental schools have adopted many of the recommendations for curricular content and learning strategies proposed in the 1989 American Association of Dental Schools (now American Dental Education Association) Curriculum Guidelines on Ethics and Professionalism in Dentistry. The survey was sent to the individual who directs the ethics curriculum at the fifty-six U.S. dental schools that had a full complement of enrolled predoctoral classes as of January 2008. All fifty-six schools responded to the survey. The data suggest that, in general, little time is devoted to ethics instruction in the formal curriculum. The mean number of contact hours of ethics instruction is 26.5 hours, which represents about 0.5 percent of the mean clock hours of instruction for dental education programs reported in the most recent American Dental Association survey of dental education. While the amount of time devoted to ethics instruction appears not to have changed much over the past thirty years, what has changed are what qualifies as ethics instruction, the pedagogies used, and the development and availability of norm-referenced learning outcomes assessments, which are currently used by a number of schools. We found that dental schools address a substantial list of topics in their ethics instruction and that there is general agreement as to the appropriateness of the topics and the ethics competencies that need to be developed and assessed. This study also identified the respondents' perceptions of unmet needs in ethics education. Four general themes emerged: the need for ethics to be more fully

    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 study was designed to survey the curricular requirements, types of clinical experience, and materials/ techniques used in teaching programs for all-ceramic restorations in Scandinavian dental schools. All 13 dental schools responded. Ten offered some clinical experience to pre-doctoral students, but only one required one all-ceramic restoration. The departments of fixed prosthodontics had the main teaching responsibility. All-ceramic crowns were taught at 9, veneers at 7, and inlays/onlays at 10 dental schools. A wide range of different teaching concepts, materials, and views on indications and contraindications was reported. It appears as if all-ceramic restorations are regarded as experimental by the teaching institutions, although the dental industry and some practitioners strongly recommend these types of restorations.

    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.

    In recent years, the concept of a Health-Promoting School has received much interest. In Malaysia, dental nurses are ideally placed to play a lead role in promoting Oral Health within the school setting. This study aims to provide information on the knowledge, perception and perceived role of Oral Health Promotion in schools, among dental nurses. A postal questionnaire was used to measure dental nurses' knowledge, perception and perceived role of Oral Health Promotion. The majority (60%) of dental nurses had good knowledge of Oral Health Promotion. Generally, they perceived that they play an important role in promoting Oral Health in schools. However, a sizeable proportion (25%) did not think they had a role to play in working together with school authorities to provide children with healthy food choices in school canteens. The majority (60%) of dental nurses did not perceive Oral Health Promotion to be important as a whole. They had a good perception of the concepts: it supports behaviour change, it has appropriate goals, it integrates oral health and general health and relieves anxiety. However, they had a poorer perception of the concepts; diverse educational approaches, participation, focus on prevention, early intervention, "spread of effect" of dental health education and "make healthier choices the easier choices". Years of service was not significantly associated with knowledge and perception of Oral Health Promotion. Dental nurses should be reoriented towards a more holistic practice of Oral Health Promotion. Workshops that invite active participation from dental nurses should be conducted to equip them with the necessary knowledge and skills.

    Stem cells are pluripotent cells, having a property ofdifferentiating into various types of cells of humanbody. Several studies have developed mesenchymalstem cells (MSCs) from various human tissues,peripheral blood and body fluids. These cells are thencharacterized by cellular and molecular markers tounderstand their specific phenotypes. Dental pulpstem cells (DPSCs) are having a MSCs phenotype andthey are differentiated into neuron, cardiomyocytes,chondrocytes, osteoblasts, liver cells and β cells of isletof pancreas. Thus, DPSCs have shown great potentialityto use in regenerative medicine for treatment of varioushuman diseases including dental related problems.These cells can also be developed into induced pluripotentstem cells by incorporation of pluripotencymarkers and use for regenerative therapies of variousdiseases. The DPSCs are derived from various dentaltissues such as human exfoliated deciduous teeth,apical papilla, periodontal ligament and dental follicletissue. This review will overview the information aboutisolation, cellular and molecular characterization anddifferentiation of DPSCs into various types of humancells and thus these cells have important applications inregenerative therapies for various diseases. This reviewwill be most useful for postgraduate dental students aswell as scientists working in the field of oral pathologyand oral medicine.

    The aim of this study was to investigate the opinions of the faculty and students of the University of Athens Dental School in Greece regarding the appropriate penalty for specific academic offenses. In addition, faculty and student opinions were compared. A questionnaire was distributed to officially registered seniors and full-time faculty members, and 177 individuals responded anonymously and voluntarily. The respondents were asked to select one from a set of nine penalties for each of fifteen hypothetical academic offenses and three cases with extenuating circumstances. Non-parametric Mann-Whitney U tests and a Wilcoxon signed-rank test, depending on the nature of variables, were used to detect significant differences in penalty scores between faculty and students. A p-value of <0.05 was considered statistically significant. The penalty scores for the fifteen offenses ranged from a mean of 2.23±1.55 to 7.25±2.64. Faculty respondents gave more severe penalties than students did for all offenses, and the finding was statistically significant (p<0.05) for eleven of the fifteen offenses. Where extenuating circumstances were added, the penalty selection altered in two of the three cases. A significantly more lenient penalty was selected by both faculty and students in these two cases. The results of this study suggest that faculty members are harsher than students for the same offenses and that extenuating circumstances can sometimes significantly change recommended penalties.

    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.

    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.

    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.

    The aim of this study was to investigate the existence of correlations between dental admissions criteria, including a chalk carving exercise, and students' subsequent academic performance. The retrospective cohort study examined the records of dental students at Louisiana State University Health Science Center School of Dentistry for the years 1998 to 2008. Only those students who could be categorized into the following four groups were included: 1) those who graduated in the top 10% of their class, 2) those who graduated in the bottom 10% of their class, 3) those who repeated a year of dental school, and 4) those who were dismissed or resigned. The study sample consisted of 176 students: 62 in the first group, 62 in the second group, 25 in the third group, and 27 in the fourth group. Data collected were each student's undergraduate grade point average (GPA); chalk carving score; undergraduate biology, chemistry, physics (BCP) GPA; Dental Admission Test (DAT) Academic Average; Perceptual Ability Test (PAT) score of the DAT; total DAT score; grade in preclinical operative dentistry class; grade in morphology and occlusion class; and dental school GPA at graduation. The results showed that only the undergraduate GPA and BCP GPA were significantly higher for students in the top 10% of their class than for other groups. The only positive correlation involving the chalk carving scores was with the preclinical operative dentistry course grade. This study thus found limited correlations between this institution's admissions criteria and its students' success in dental school.

    The purpose of this article is to describe the process and procedures involved in the implementation of portfolio assessment at two dental schools. Portfolios can be defined as a purposeful collection of student work that involves reflection in which students identify gaps in their knowledge and abilities and develop strategies for correcting those gaps. Framed within the current context of dental education and the calls for change in the ways dental students are taught and assessed, these two dental schools embarked upon an assessment strategy aimed at engaging students in self-directed learning and self-assessment. Where one school chose the implementation of programmatic portfolios based on all program competencies, the other school implemented portfolio assessment around specific program competencies not typically captured easily with traditional assessment measures such as ethics and ethical decision making. In a competency-based dental curriculum in which competence has been defined as the ability to accurately self-assess, it makes sense that strategies aimed at developing the skill of self-assessment should be the goal of every dental education program.

    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

    This study investigates the profile of teaching primary tooth pulp therapy practiced by Brazilian dental schools. A multiple-choice questionnaire was sent by e-mail to 191 dental schools in Brazil, addressed to the pediatric dentistry Chairperson. The two-part survey consisting of multiple-choice questions regarding specific materials and techniques on pulp therapies, moreover, hypothetical clinical scenarios were presented so that the respondents could guide the treatment approach. The questionnaires were returned by 46.5% of the dental schools. Ninety-five percent of surveyed schools teach IPT for the treatment of deep carious lesions in dentin and indicate the calcium hydroxide as capping material (59.3%). The direct pulp capping is taught by 68.7% of schools and calcium hydroxide (97%) was the capping material most indicated. Pulpotomy is taught in 98.7% of schools and formocresol (1:5 dilution) was the medicament of choice (50%). All schools taught pulpectomy and Iodoform paste was the filling material preferred (55%). The results showed a lack of consensus in certain modalities and techniques for primary tooth pulp therapy taught by Brazilian dental schools.

    The objectives of this project were to create a program that would expose underrepresented minority (URM) and low income (LI) high school students to dental professions and provide an opportunity for dental and dental hygiene students from URM/LI groups to be engaged in teaching activities. Data were collected from participants during the school years 2009-10 (high school students: N=23, dental students: N=21, dental hygiene students: N=5) and 2010-11 (N=27, N=11, N=3, respectively). The students participated in fifteen Saturday sessions from October through March each year. The data showed that, from the beginning, mentees and mentors were very interested in participating in the program and getting to know each other. Lectures, general program activities, and patient-related events such as organizing a health fair and shadowing during two outreach clinics were evaluated positively by mentees and mentors. The end of program evaluations showed that the program and the mentee-mentor relationships were rated very positively and that the mentees had an increased interest in oral health-related careers. In conclusion, creating opportunities for URM/LI high school students to explore dental careers and for dental and dental hygiene students to engage in teaching resulted in positive experiences for both groups.

    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

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.

    The purpose of this study was to identify the performance differences between two groups of Austrian dental students (one with a prior medical degree and one without a medical degree) during their dental school training and final dental licensure examination. A specific aim was to determine if having a medical degree is a predictive factor for dental students' scores on the Austrian Dental Admission Test (Austrian DAT), performance in the dental clinic, and scores on final exam. The study consisted of a retrospective analysis of 122 students (thirty-nine with a medical degree and eighty-three without a medical degree) who were enrolled in the Dental Clinic at Innsbruck Medical University, Innsbruck, Austria, between 2001 and 2006. Three performance categories were considered: Austrian DAT results, clinical performance after the first clinical year in dental school, and performance on the final dental licensure examination. Information on students' age, gender, and previous medical degree was collected from official records. Analyses with student's t-test and Pearson's chi-square test revealed that the students with a medical degree had significantly higher Austrian DAT total test scores, grade point averages after the first clinical year, and scores on the final exam. Additionally, those students had significantly better performance on the final exam in prosthodontics and oral and maxillofacial surgery. The linear regression analysis showed that a medical degree had an independent effect on average scores on the final exam, age, and Austrian DAT test scores, while gender showed no statistically significant effect. Overall, the study found that dental students with a prior medical degree had significantly higher Austrian DAT total test scores and performed significantly better in the first clinical year and on the final exam than those without a prior medical degree.

    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.

    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 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.

    Implant placement is often necessitated for replacement of teeth with pathologically damaged alveolar bone due to periodontitis or traumatic injury. Surgical augmentation of resorbed bone has many limitations, including lower efficacy of vertical augmentation than horizontal augmentation, as well as morbidity associated with grafting procedure. Orthodontic therapy has been proposed as a useful method for augmenting the resorbed alveolar bone and reforming aesthetically appealing gingival margin, prior to implant placement. This narrative review summarizes the available evidence for the application of orthodontic strategies that can be used as adjunct in selected cases to augment bone volume for the future implant site and maintain space for the prosthetic parts of the implant. These are (1) orthodontic extrusion of compromised teeth to generate vertical bone volume and enhance gingival architecture, (2) tooth preservation and postponing orthodontic space opening to maintain bone volume in future implant site, (3) orthodontic implant site switching to eliminate the deficient bone volume or risky implant sites, and (4) the provision of a rigid fixed-bonded retainer to maintain the implant site. Although there are no randomized controlled clinical trials to evaluate the efficacy of orthodontic therapy for implant site development, clinical case reports and experience document the efficacy of orthodontic therapy for this application.

    Dental pain is considered an important public health problem because it affects the daily life of children. This study was designed to assess the prevalence, associated factors, and impact of dental pain among 8-12-year-old school children in Lagos, Nigeria. A cross-sectional survey to determine self-reported dental pain among 8-12-year-old school children using an interviewer-administered questionnaire was conducted. This was followed by a clinical examination to determine the child's oral hygiene status and dental caries status. Chi-square and Fisher's exact tests were used for comparing proportions. Binary logistic regression analysis was also conducted. Statistical significance was set at P dental pain 3 months and 4 weeks before the survey, respectively. Caries prevalence was 21.0%, whereas mean decayed, missing, and filled tooth index score was 0.4420 (±1.078). A report of pain up to 3 months before the survey was significantly associated with the child's age [odds ratio (OR) = 1.254; confidence interval (CI) = 1.037-1.516; P = 0.019], whereas the type of school attended (OR = 1.786; CI = 1.124-2.840; P = 0.014) and the presence of dental caries (OR = 1.738; CI = 1.023-2.953; P = 0.041) were significantly associated with reporting pain 4 weeks before the survey. The prevalence of self-reported dental pain was high among the children surveyed. Report of dental pain was associated with the presence of dental caries. The provision of school oral health services could be useful in reducing the level of untreated caries and possibly dental pain among school children.

    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.

    2017-03-01

    Second-year dental students are commonly instructed on the process of complete denture fabrication with a traditional didactic lecture and preclinical dental laboratory education model. The problem with this limited mode of instruction is that dental students often fail to understand the various chairside procedures required to fabricate a complete denture. The aim of this study was to investigate the use of standardized dental patients to enhance students' understanding of the procedures involved with each appointment in the complete denture process. The Midwestern University College of Dental Medicine-Arizona created an event using standardized patients in four simulated chairside dental appointments for complete denture instruction of second-year dental students. Each appointment simulated the various sequential chairside procedures required to fabricate complete dentures. Following the didactic and dental laboratory instruction and the standardized patient event, a survey was conducted requesting the students' response to six statements regarding their understanding of the denture fabrication process. Of the 110 students who participated in the instructional events, 107 responded to the survey (97% response rate). These students responded very favorably to the simulated appointments, with the majority agreeing or strongly agreeing that their best understanding of the complete denture process was obtained through the standardized patient experiences. The use of standardized patients in simulated denture fabrication appointments enhanced the educational experience of these students when added to the traditional didactic lecture and preclinical laboratory education format. The experience has since been incorporated into the school's second-year oral health science laboratory curriculum.

    Electrospinning has been employed extensively in tissue engineering to generate nanofibrous scaffolds from either natural or synthetic biodegradable polymers. Three-dimensional electrospun scaffolds can create a multi-scale environment capable of facilitating cell adhesion, proliferation, and differentiation. One such multi-scale scaffold incorporates nanofibrous features to mimic the extracellular matrix along with a porous network for the regeneration of a variety of tissues. This review will discuss nanofibrous scaffolds and their tissue-engineering applications in bone, cartilage, periodontium, tooth, and incorporated drug delivery systems. Combination with other technologies, electrospun scaffolds can contribute to the field of craniofacial regeneration and advance technology for tissue-engineered replacements in many physiological systems in near future.

    Tissue-engineering solutions often harness biomimetic materials to support cells for functional tissue regeneration. Three-dimensional scaffolds can create a multi-scale environment capable of facilitating cell adhesion, proliferation, and differentiation. One such multi-scale scaffold incorporates nanofibrous features to mimic the extracellular matrix along with a porous network for the regeneration of a variety of tissues. This review will discuss nanofibrous scaffold synthesis/fabrication, biological effects of nanofibers, their tissue- engineering applications in bone, cartilage, enamel, dentin, and periodontium, patient-specific scaffolds, and incorporated growth factor delivery systems. Nanofibrous scaffolds cannot only further the field of craniofacial regeneration but also advance technology for tissue-engineered replacements in many physiological systems.

    Full Text Available 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.

    Full Text Available Statement of problem: Dental caries are considered as one of the most common health problems and have been shown to be more prevalent in children.Purpose: The aim of this cross-sectional study was to determine the distribution of dental caries among 400 twelve-year-old schoolchildren, in the Al-Mukalla area in Yemen.Materials and Methods: Multistage stratified sampling was used to obtain a sample size of 400 children, consisting of 200 males and 200 females with mixed dentitions.All subjects were selected from two private schools and five public schools. Clinical examinations were performed under standardized conditions by a trained examiner.Results: Dental caries was found in 198 (49.5% of the 400 schoolchildren including 51.5% males and 48.5% females. The prevalence of caries was higher (p<0.05 in permanent teeth (76.6%, in urban areas and in the mandible (54%; compared to deciduous teeth, rural regions and the maxilla, respectively. Private schools (57%revealed a larger number of affected cases as compared to public schools. Dental caries were more prevalent in children living in areas that received their water supply from Al-Ghail, in comparison to those residing in regions supplied from Al-Taweela water source (p<0.05. Caries were the primary cause of missing teeth in 8% of the subjects.Conclusion: Considering that dental caries can be associated with children’s school grade, dental services should be directed toward preschool children with a preventive policy through dental health education.

    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.

    Full Text Available Background: Regular use of dental services has been associated with optimal oral health. Reports in some parts of Nigeria have shown the poor utilization of dental services, but there is a paucity of information relating to oral health care seeking behavior in the South-South region of Nigeria. Aim: To determine the pattern of utilization and identify barriers to utilization of dental services among children. Materials and Methods: This was a cross-sectional study done among children aged 12-15 years in secondary schools in Port Harcourt, Nigeria. Information was elicited by means of a self-administered structured questionnaire. These included sociodemographic characteristics, views on dental visits, reported visits during the previous year, pattern of dental visits, and the barriers to utilization. Demographic variables and associations were tested using Chi-squared tests with the level of statistical significance set at P < 0.05 at 95% confidence interval. Results: There were 200 school children; 98 (49% males and 102 (51% females with a mean age of 13.3 (΁1.1 years. Dental visits were deemed important by 187 (93.5% children, and 32.0% respondents suggested that visits should be when there are symptoms. Only 42 (21% pupils had been to the dentist in the last 12 months. The barriers to utilization of dental services majorly included no perceived needs (64.3%. Demographic variables had no significant association with reported visits and pattern of visits. Conclusion: Utilization of dental services among these school children was low and the major barrier was no perceived need. Oral health awareness needs to be improved on the importance of a regular checkup.

    Dental students have little input into the selection of course topics and subject matter included in their dental curricula. Curriculum requirements are framed by the Commission on Dental Accreditation, which has stipulated competencies and associated biomedical and clinical knowledge that must be addressed during dental school. Although these competency requirements restrict the variance of educational experiences, students are eager to share their views on the curriculum within the realm of their educational experience. The objective of this research project was to elicit the perspectives of dental students from a broad cross-section of U.S. and Canadian dental schools about their education. A total of 605 students (285 sophomores, 220 seniors, 100 residents) from twenty North American dental schools completed a SWOT (Strengths, Weaknesses, Opportunities, and Threats) analysis to communicate their perceptions of the curriculum. Students were also asked to provide their impressions of the overall quality of the educational program in an open-ended written format. The students' qualitative comments were then reviewed and categorized into key issues or themes. Resulting themes for each category of the Curriculum SWOT (C-SWOT) analysis were the following. Strengths: 1) clinical learning experience, and 2) opportunity to work with knowledgeable faculty. Weaknesses: 1) disorganized and inefficient clinical learning environment, 2) teaching and testing that focus on memorization, 3) poor quality instruction characterized by curricular disorganization, and 4) inconsistency among instructors during student evaluations. Opportunities: 1) develop strategies to provide students with more exposure to patients, especially early in the curriculum, and 2) opportunities to learn new technology/techniques. Threats: 1) cost of dental education, 2) students' concerns about faculty "brain drain," i.e., lack of sufficient numbers of dental faculty capable of providing high

    Maintenance of health and preservation of tooth structure through risk-based prevention and patient-centered, evidence-based disease management, reassessed at regular intervals over time, are the cornerstones of present-day caries management. Yet management of caries based on risk assessment that goes beyond restorative care has not had a strong place in curriculum development and competency assessment in U.S. dental schools. The aim of this study was to develop a competency-based core cariology curriculum framework for use in U.S. dental schools. The Section on Cariology of the American Dental Education Association (ADEA) organized a one-day consensus workshop, followed by a meeting program, to adapt the European Core Cariology Curriculum to the needs of U.S. dental education. Participants in the workshop were 73 faculty members from 35 U.S., three Canadian, and four international dental schools. Representatives from all 65 U.S. dental schools were then invited to review and provide feedback on a draft document. A recommended competency statement on caries management was also developed: "Upon graduation, a dentist must be competent in evidence-based detection, diagnosis, risk assessment, prevention, and nonsurgical and surgical management of dental caries, both at the individual and community levels, and be able to reassess the outcomes of interventions over time." This competency statement supports a curriculum framework built around five domains: 1) knowledge base; 2) risk assessment, diagnosis, and synthesis; 3) treatment decision making: preventive strategies and nonsurgical management; 4) treatment decision making: surgical therapy; and 5) evidence-based cariology in clinical and public health practice. Each domain includes objectives and learning outcomes.

    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 investigated the use of the FDI tooth notation system in UK dental schools. In addition, the notation system used by dentists referring patients to Manchester Dental Hospital was recorded. A questionnaire was sent to the Deans of all Dental Schools in the UK and letters of referral to Manchester Dental Hospitals Paediatric GA Service were monitored for 1 month. The results showed that only Manchester University Dental School used the FDI system but 6 other schools instructed students in its use. The Palmer system was used by all the other schools for recording clinical information. 136 referral letters were received, only one used the FDI notation, 15 used both FDI and Palmer and the remainder (120) requested extractions using the Palmer notation. The FDI notation system is not used in the majority of UK dental schools. Despite the fact the Dental School in Manchester has been teaching and using the FDI system for over 10 years, it has not been adopted by General Dental Practitioners referring patients into the hospital. The FDI should review the use of their system in other countries, to ascertain whether it has fulfilled its role as an international notation system.

    Previous studies have suggested that dental students may not receive sufficient clinical experience in core paediatric dentistry skills. This study aimed to compare dental undergraduates' self-reported experience and confidence in paediatric dentistry within three UK dental schools (Liverpool, Manchester and Sheffield). In April/May 2009, 147 final year dental students completed an anonymous questionnaire which captured their experience of seven core clinical skills in both hospital and outreach settings. A visual analogue scale was also employed to record perceived levels of confidence for six generic activities including: examination, diagnosis and treatment planning; patient selection for treatment under general anaesthesia; operative dentistry; preventive dentistry; management of dento-alveolar trauma, and provision of routine care for children on qualification. The key finding was that Liverpool, Manchester and Sheffield dental students received comparable clinical experiences in paediatric dentistry, which appeared to satisfy the requirements of the General Dental Council's The first five years. One hundred percent had carried out fissure sealants and restorations, and 87-98% had experience of extractions. Outreach placements were crucial in ensuring students had sufficient opportunity to undertake core skills, notably extractions and pulp therapies. All students reported a lack of confidence in dental trauma management which warrants greater emphasis in the undergraduate curriculum.

    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 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.

    The aim of this study was to evaluate and compare a group of Indian dental students' attitudes toward HIV-positive status, substance misuse, intellectual disability, acute mental illness, and lesbian, gay, bisexual, transgender (LGBT) orientation. Two hundred and twelve students at various stages in the dental curriculum anonymously completed the Medical Condition Regard Scale (MCRS) for these conditions. Friedman and Kruskal-Wallis tests were used, respectively, to analyze the intrastage and interstage differences in MCRS scores. The results revealed that the regard of dental students was considerably positive for all the conditions except LGBT, for which it was just borderline positive. Intellectual disability received the highest regard among all the conditions and LGBT the least. An intermediary and comparable regard was noted for acute mental illness and HIV-positive status followed by substance misuse. While the regard for LGBT remained consistent throughout the curriculum, those for other conditions showed a marginal decrease at the completion of the clinical training. Active curricular reforms are required to ensure a more inclusive and nondiscriminatory dental care environment for patients from such often-stigmatized populations, especially those with LGBT orientation and substance misuse.

    This study was conducted to determine the prevalence and severity of dental fluorosis among secondary school children in Ibadan, Nigeria. A multi-stage sampling technique was employed to select the participants who consisted of children aged 12-14 years taken from eleven randomly selected secondary schools in the five local government areas of Ibadan Metropolis. The children were examined by the Principal Investigator after submitting parental administered questionnaires. The diagnosis of dental fluorosis was based on the TF index. The mean age of the 1372 participants (825 males and 547 females) was 13.15 ± 0.80 years. Dental fluorosis was diagnosed in 157 (11.4%) children (98 males and 59 females). There was no statistically significant difference between age or gender and the occurrence of fluorosis. Most of the cases were very mild with greater than 90% of the affected teeth having a TF score of ≤3. The most severely affected were the maxillary molars. Severe disfiguring cases of dental fluorosis were not common among the secondary school children examined. The prevalence of dental fluorosis was found to be low, with majority of the cases being very mild.

    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 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.

    Objective Limited data exist on musculoskeletal problems within dental students: we aimed to determine the prevalence of these disorders.Design Single centre cross-sectional study.Setting A UK Dental School 2015.Methods Students completed a modified Nordic pain questionnaire.Main outcome measures Self-reported frequency and severity of pain, fitness and coping strategies.Results 63% of 390 respondents were female and 75% aged under 23. Seventy-nine percent experienced pain with 42% experiencing pain for 30 or more days in the past year. Lower back pain was most common (54%) and was most frequently the worst area of pain (48%). Thirty-six percent reported pain lasting at least four hours. The mean 'average pain intensity' VAS score was 3.81/10 (sd = 1.75) and mean 'worst pain intensity' was 5.56 (sd = 2.10). More females reported neck pain (58% versus 37%, P pain intensity' (mean 4.02, sd 1.82 versus 3.43 sd 1.55, P = 0.012. Daily stretching was used by 55.7% of respondents, and this positively correlated with 'average' and 'worst pain intensity' (P = 0.096 and P = 0.001) scores. Eighteen percent sought professional help to manage pain.Conclusion Musculoskeletal pain is a problem for dental students. Education in self-care may be helpful; however, assessments of possible interventions are needed.

    The routine evaluation of teaching effectiveness is important in improving faculty, departmental, and institutional efforts. There are three main categories of assessments: those performed by students, peers, and self. Although each category is independently valid, a collection of data from all three categories leads to a more comprehensive outcome and a creation of a triangulation model. The purpose of this study was to identify commonly used methods of assessing teaching effectiveness and to suggest the use of a triangulation model, which has been advocated in the literature on performance assessment as an optimal approach for evaluating teaching effectiveness. A twelve-question survey was sent to all U.S. dental schools to identify evaluation methods as well as to find evidence of triangulation. Thirty-nine out of fifty-seven schools responded. The majority of the schools used student evaluations (81 percent) and peer reviews (78 percent). A minority of schools reported using self-evaluations (31 percent). Less than one in five dental schools reported using all three strategies to achieve triangulation (19 percent). The three most commonly used evaluation methods ("performed routinely") were all in the student evaluation category. Less than half of the schools routinely evaluated clinical teaching effectiveness by any means (42 percent). In conclusion, dental schools should implement a triangulation process, in which evaluation data are obtained from students, peers, and self to provide a comprehensive and composite assessment of teaching effectiveness.

    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.

    Dental caries is the most common chronic infectious disease of childhood caused by the interaction of bacteria, mainly Streptococcus mutans and sugary foods on tooth enamel. This study aimed at determining the prevalence and associated factors of dental caries among primary school children at Bahir Dar city. A school based cross-sectional study was conducted at Bahir Dar city from October 2013 to January 2014. Systematic random sampling technique was used to select the children. Structured questionnaire was used to interview children and/or parents to collect socio demographic variables. Clinical dental information obtained by experienced dentist using dental caries criteria set by World Health Organization. Binary and multiple logistic regression analysis were computed to investigate factors associated with dental caries. Of the 147 children, 82 (55.4%) were girls. Majority of the children (67.6%) cleaned their teeth using traditional method (small stick of wood made of a special type of plant). The proportion of children having dental caries was 32 (21.8%). Primary tooth decay accounted for 24 (75%) of dental caries. The proportion of missed teeth was 7 (4.8%). The overall proportion of toothache and dental plaque among school children were 40 (27.2%) and 99 (67.3%), respectively. Grade level of 1-4 (AOR = 3.9, CI = 1.49 -10.4), poor habit of tooth cleaning (AOR = 2.6, CI = 1.08 - 6.2), dental plaque (AOR = 5.3, CI = 1.6 - 17.7) and toothache (AOR = 6.3, CI = 2.4 - 15.4) were significantly associated with dental caries. Dental caries is a common public health problem in school children associated with poor oral hygiene, dietary and dental visit habits. Therefore, prevention measures such as health education on oral hygiene, dietary habits and importance of dental visit are obligatory for children.

    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.

    This 3-year retrospective controlled clinical trial assessed the effect of a school-based oral health education program on caries incidence in children. A total of 240 students, aged 5 to 7 years, from two public schools in Monte Sião, Brazil, were included in this study. A school-based oral health education program was developed in one of the schools (experimental group), including 120 students, while the 120 students from the other school did not participate in the program (control group). All children were initially examined for dental caries (dmf-t), and after 3 years, 98 children from the experimental group and 96 from the control group were again examined and answered a questionnaire on oral health issues. The between-groups difference in caries incidence on permanent teeth was calculated using Poisson regression analyses. Logistic regression was used to observe the association between caries incidence and other variables. More students from the experimental group stated knowing what was dental caries and declared that they use dental floss daily, but no significant differences in caries incidence was observed between the experimental and control groups. The school-based oral health education program is not adequately efficient to decrease caries incidence after three years, but some issues about oral health knowledge could be slightly improved.

    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.

    By using a standard questionnaire, the level of dental brushing frequency was assessed among 201 adolescent female middle school students in Tehran. The initial assessment was repeated after 5 months, in order to observe the dynamics in dental health behavior level. Logistic Regression model was used to evaluate the correlation among individuals' dental health behavior in their social network. A significant correlation on dental brushing habits was detected among groups of friends. This correlation was further spread over the network within the 5 months period. Moreover, it was identified that the average brushing level was improved within the 5 months period. Given that there was a significant correlation between social network's nodes' in-degree value, and brushing level, it was suggested that the observed improvement was partially due to more popularity of individuals with better tooth brushing habit. Agent Based Modeling (ABM) was used to demonstrate the dynamics of dental brushing frequency within a sample of friendship network. Two models with static and dynamic assumptions for the network structure were proposed. The model with dynamic network structure successfully described the dynamics of dental health behavior. Based on this model, on average, every 43 weeks a student changes her brushing habit due to learning from her friends. Finally, three training scenarios were tested by these models in order to evaluate their effectiveness. When training more popular students, considerable improvement in total students' brushing frequency was demonstrated by simulation results.

    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.

    Full Text Available Context: Fluorosis is an endemic disease resulting due to excess ingestion of fluoride. Ground water has been a significant water source for domestic, irrigating, and industrial purposes in India. India is placed in a geographical fluoride belt. Kolar, a drought prone area with semiarid climate, is one among 16 fluorosis endemic districts of Karnataka. Aims: To study the prevalence of dental fluorosis among school children and to estimate the fluoride levels in drinking water sources. Settings and Design: A cross-sectional study was conducted among school-going children. Materials and Methods: School-going children from two randomly selected schools of two randomly selected Panchayat areas of Kyasamballi and Gollahalli were studied in August 2011. All the children in these schools were evaluated for dental fluorosis based on Dean′s index. Fluoride levels of drinking water sources in these communities were estimated by ion-electrode method. Statistical analysis: The data were analyzed with Epi-info 7 statistical software and expressed in proportions. Chi-square test was employed to test the significance. Results: A total of 380 children in the age group of 6-15 years were studied. The prevalence of dental fluorosis was 31.05%, predominant in females. The community fluorosis index was 0.718 indicating slight public health importances. The fluoride levels in drinking water sources exceeded 1.5 mg/L. Conclusion: Dental fluorosis is a public health problem in Kolar. High fluoride content in the sources of drinking water is the main reason for dental fluorosis, suggesting an urgent need for defluoridation of water sources with sustainable long-term measures in Kolar.

  16. The demographic and academic profile of Irish dental school faculty members.

    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.

  18. Application of fuzzy classification in modern primary dental care

    Directory of Open Access Journals (Sweden)

    Yauheni Veryha

    2005-03-01

    Full Text Available This paper describes a framework for implementing fuzzy classifications in primary dental care services. Dental practices aim to provide the highest quality services for their patients. To achieve this, it is important that dentists are able to obtain patients' opinions about their experiences in the dental practice and are able to accurately evaluate this. We propose the use of fuzzy classification to combine various assessment criteria into one general measure to assess patients' satisfaction with primary dental care services. The proposed framework can be used in conventional dental practice information systems and easily integrated with those already used. The benefits of using the proposed fuzzy classification approach include more flexible and accurate analysis of patients' feedback, combining verbal and numeric data. To confirm our theory, a prototype was developed based on the Microsoft TM SQL Server database management system for two criteria used in dental practices, namely making an appointment with a dentist and waiting time for dental care services.

    2013-01-01

    During the 1960s, the dental school at the University of Buffalo underwent a profound change, as a result of its merger with the State University of New York (SUNY), and, very importantly, because of the outstanding leadership provided by Dean James A. English. This article contrasts what the school was like in 1960 before Dean English's arrival, and what it had become in 1970 when his deanship ended. It also recounts the leadership qualities of Dean English and the measures he took to transform the dental school into a leading educational institution. During his tenure, the school experienced profound change, including integration of medicine with dentistry in the curriculum; "internationalization" of dental education and research; organization of the first Oral Biology Department and PhD graduate program in a dental school in the United States; insistence on "knowledge-driven" dental practice--a concept we now term "evidenced-based dentistry"; the establishment of novel approaches to dental education including the "diagonal" curriculum; incorporation of prevention in practice; elective courses for dental students; and comprehensive clinical care. All of these accomplishments were novel for the day and greatly influenced incorporation of similar innovations in many schools around the world.

  2. High elastic modulus nanopowder reinforced resin composites for dental applications

    Wang, Yijun

    2007-12-01

    Dental restorations account for more than $3 billion dollars a year on the market. Among them, all-ceramic dental crowns draw more and more attention and their popularity has risen because of their superior aesthetics and biocompatibility. However, their relatively high failure rate and labor-intensive fabrication procedure still limit their application. In this thesis, a new family of high elastic modulus nanopowder reinforced resin composites and their mechanical properties are studied. Materials with higher elastic modulus, such as alumina and diamond, are used to replace the routine filler material, silica, in dental resin composites to achieve the desired properties. This class of composites is developed to serve (1) as a high stiffness support to all-ceramic crowns and (2) as a means of joining independently fabricated crown core and veneer layers. Most of the work focuses on nano-sized Al2O3 (average particle size 47 nm) reinforcement in a polymeric matrix with 50:50 Bisphenol A glycidyl methacrylate (Bis-GMA): triethylene glycol dimethacrylate (TEGDMA) monomers. Surfactants, silanizing agents and primers are examined to obtain higher filler levels and enhance the bonding between filler and matrix. Silane agents work best. The elastic modulus of a 57.5 vol% alumina/resin composite is 31.5 GPa compared to current commercial resin composites with elastic modulus alumina, diamond/resin composites are studied. An elastic modulus of about 45 GPa is obtained for a 57 vol% diamond/resin composite. Our results indicate that with a generally monodispersed nano-sized high modulus filler, relatively high elastic modulus resin-based composite cements are possible. Time-dependent behavior of our resin composites is also investigated. This is valuable for understanding the behavior of our material and possible fatigue testing in the future. Our results indicate that with effective coupling agents and higher filler loading, viscous flow can be greatly decreased due to the

    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.

    2014-06-01

    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.

    Full Text Available Introduction: Healthy teeth are important for any section of society. Dental caries, the product of man's progress toward civilization, has a very high morbidity potential. Fluoride has been recognized as one of the most influential factor responsible for the observed decline of caries among children as well as adults of these countries. While fluoride is accepted as an effective method to prevent caries, the excessive consumption of fluoride can put teeth at risk of developing dental fluorosis. Aims and Objectives: To assess the prevalence of dental fluorosis among 12–15 years old government and private school children of Bharatpur city, Rajasthan. Methodology: A cross-sectional study was carried out on total 1400 school children, out 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 fluorosis according to WHO 1997 assessment form. Results: The prevalence of dental fluorosis was found higher among government school children, that is, 54.5% when compared to private school children, that is, 45.5% respectively, and this difference was found to be statistically significant (P ≤ 0.05. Conclusion: The study showed the increased prevalence of dental fluorosis among government school children as compared to private school children. Dental fluorosis was found to be the major public health problem among both government and private school children of Bharatpur city which needed immediate attention. Regular dental check-ups and routine oral hygiene practice will enable them to lead a healthier life.

    The term 'oral health care for older adults' has various interpretations, and its meaning is not clear among dental school academic staff. Additionally, there are no theoretical or practical stand-alone courses on oral health care for older adults in Japanese dental schools. To improve oral health care education, we investigated the opinions and attitudes toward oral health care education for older adults among academic staff in dental schools. Data were collected in seven dental schools from May to September 2013 via an online questionnaire survey. Five-hundred-fifty-eight academics (428 male, 130 female) participated (response rate 57%). The average number of years since they had completed a university degree was 20.2 (SD 10.2) years. The majority (Over 90%) of participants perceived that oral health care should be provided in nursing facilities, hospitals, and at home. Its treatments and instructions should include, not only methods of keeping good oral hygiene, but also improvement of oral function such as swallowing training and salivary glands massage. The majority (84.2%) suggested oral health care education should be combined as a one-credit, stand-alone course. Findings indicate that dental academics have an understanding the need for a course in oral health care for older adults. Participants supported the need for further development of education in oral health care for older adults' in Japan, as a separate course on its own right. However there were some different views about content by teaching field. The need for a national core program for teaching oral health care education was suggested.

    Approaches for managing carious tissues during cavity preparations vary considerably among clinicians, which may reflect inconsistencies in the teaching of this subject by dental schools. The aims of this study were to investigate practices related to the preclinical and clinical teaching of caries removal at U.S. dental schools and the relationship between that teaching and requirements for U.S. dental licensure examinations. The electronic survey included questions about terminology, methods, instruments and materials, treatment planning, criteria for clinical exams, faculty calibration sessions, and licensure exams. The faculty members at U.S. dental schools responsible for teaching cariology were invited to participate; 54 of the 65 schools had identified a contact person at the time of the survey in October 2015. Of those 54 invited to participate, 43 completed the survey (response rate of 79.6%). Most of the respondents indicated that depth of carious lesions was a clinical determinant of the amount of carious dentin being removed in cavity preparations. Caries removal was used as a criterion in restorative clinical examinations by 95% of responding schools. Marked differences were observed regarding the criteria used for assessment and removal of carious tissues, management of deep carious lesions, and definition of "caries remaining at cavity preparations," which is considered a critical error on licensure exams. Faculty calibration sessions on caries removal were reported to occur in 65% of these schools and at different time frames. Overall, the study found a wide range of teaching practices related to caries removal. Best evidence in caries management needs to be aligned with teaching and the criteria used to calibrate faculty members and examiners.

    The aim of this work was the comparison of calendar age with dental age in the aspect of basic nutritional ingredients intake with precise taking into consideration microelements, macroelements and vitamins. 79 schoolchildren from swimming classes of championship school in Cracow aged 10-13 were included in the examination. Among this group of pupils 24-hour recall and complex dental examination including the estimation of dental status, the hygienic status of oral cavity were conducted and the presence of dental and occlusion defects were estimated. 24-hour recall including 3 following days contained the number of products in every meal, the number of meals and the time of their consumption. The schoolchildren were divided into 3 groups on the ground of the difference between dental and calendar age. Dentition on time (no more than 5 months difference between dental and calendar age) was stated by 25 pupils--group I. Accelerated dentition of fixed teeth was observed by 36 pupils--group II and delayed dentition by 18 persons--group III. In all groups lower than safe calcium intake (80% of pupils from these groups) and iron intake (55%) was noticed. In the range of left micro- and macroelements the disturbances in nutritional status were mainly stated bypersons with delayed dentition. The shortages in Magnesium intake concerned 67% of school children and in Zinc intake--72%. In the group of schoolchildren with accelerated dentition these shortages were about 40%. In the range of vitamins intake low niacin intake (39% of schoolchildren) and riboflavin intake (25%) were stated. The differences among these groups were observed only in thiamine intake (33% from group II and 19% from group III). In the group III more often low energetic value of daily nutrient intake was stated.

    Objective The aim of the present study was to compare the costs of teledentistry and traditional dental screening approaches in Australian school children.Methods A cost-minimisation analysis was performed from the perspective of the oral health system, comparing the cost of dental screening in school children using a traditional visual examination approach with the cost of mid-level dental practitioners (MLDPs), such as dental therapists, screening the same cohort of children remotely using teledentistry. A model was developed to simulate the costs (over a 12-month period) of the two models of dental screening for all school children (2.7million children) aged 5-14 years across all Australian states and territories. The fixed costs and the variable costs, including staff salary, travel and accommodation costs, and cost of supply were calculated. All costs are given in Australian dollars.Results The total estimated cost of the teledentistry model was $50million. The fixed cost of teledentistry was $1million and that of staff salaries (tele-assistants, charters and their supervisors, as well as information technology support was estimated to be $49million. The estimated staff salary saved with the teledentistry model was $56million, and the estimated travel allowance and supply expenses avoided were $16million and $14million respectively; an annual reduction of $85million in total.Conclusions The present study shows that the teledentistry model of dental screening can minimise costs. The estimated savings were due primarily to the low salaries of dental therapists and the avoidance of travel and accommodation costs. Such savings could be redistributed to improve infrastructure and oral health services in rural or other underserved areas.What is known about the topic? Caries is a preventable disease, which, if it remains untreated, can cause significant morbidity requiring costly treatment. Regular dental screening and oral health education have the great potential

    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.

    The integration of basic and clinical sciences in dental curricula enhances the application of basic science principles to clinical decision making and improves students' critical thinking. The aim of this study was to define the characteristics of U.S. dental schools' curricula with regard to level of course integration and degree of incorporation of problem-based and case-based learning. A second aim was to propose a dental curriculum that supports effective integration of courses and addresses some of the concerns facing academic dentistry. A survey was sent to 58 academic deans in U.S. dental schools. The survey included questions about integrating courses in the schools' curricula and major changes in curricular structure or teaching pedagogy that respondents anticipated in the immediate future. A total of 31 schools responded to the survey, for a 53.4% response rate. The results showed that three-quarters of the responding schools still teach basic and clinical sciences separately, although 61.3% reported having an integrated curriculum. Among the responding schools, 16 had a PBL component integrated into their curricula (two had integrated PBL in all courses and 14 used a hybrid PBL approach). Two schools had CBL integrated in all courses, and ten had CBL integrated in >75% of courses. Only slightly more than half agreed that their curricula foster students' thinking "outside the box." Faculty shortages and lack of protected time and resources were the most frequent reasons given for a lack of integrated courses. The integrated model proposed in this article has the potential to provide a low stress environment for students and to address important issues like faculty shortages.

    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 pInterdisciplinary thinking" (∆+0.47), "Dental medical knowledge" (∆+0.43), "Practical dental skills" (∆+0.21), "Team work" (∆+0.16) and "Independent learning/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.

    Fluorides are used in dental care due to their beneficial effect in tooth enamel de-/remineralization cycles. To achieve a desired constant supply of soluble fluorides in the oral cavity, different approaches have been followed. Here we present results on the preparation of CaF2 particles and their characterization with respect to a potential application as enamel associated fluoride releasing reservoirs. CaF2 particles were synthesized by precipitation from soluble NaF and CaCl2 salt solutions of defined concentrations and their morphology analyzed by scanning electron microscopy. CaF2 particles with defined sizes and shapes could be synthesized by adjusting the concentrations of the precursor salt solutions. Such particles interacted with enamel surfaces when applied at fluoride concentrations correlating to typical dental care products. Fluoride release from the synthesized CaF2 particles was observed to be largely influenced by the concentration of phosphate in the solution. Physiological solutions with phosphate concentration similar to saliva (3.5 mM) reduced the fluoride release from pure CaF2 particles by a factor of 10-20 × as compared to phosphate free buffer solutions. Fluoride release was even lower in human saliva. The fluoride release could be increased by the addition of phosphate in substoichiometric amounts during CaF2 particle synthesis. The presented results demonstrate that the morphology and fluoride release characteristics of CaF2 particles can be tuned and provide evidence of the suitability of synthetic CaF2 particles as enamel associated fluoride reservoirs.

    Dental caries is the most common childhood disease and the most frequent non-communicable disease worldwide. In developing countries, a vast majority of the caries remains unrestored. However, the severity and consequences of untreated dental caries among Nigerian children is unknown. To determine the prevalence using the DMFT/dmft index and severity of oral conditions related to dental caries using the PUFA/pufa index in suburban Nigerian children. The study population consisted of 1,266 randomly selected school children in Ile-Ife, Nigeria. Dental caries status was assessed using the DMFT/dmft index, described by WHO for epidemiological studies. The PUFA/pufa index was used to assess the clinical consequences of untreated dental caries. The mean dmft was 0.58 for the 4-6 years age group while the mean pufa score was 0.16 for the same age group. The mean DMFT score (0.16) was highest for the 13-16 years age group, while the mean PUFA score was 0.05 for the same age group. The prevalence of dmft > 0 was highest in the 4-6 years age group (16.9 %) while the prevalence of DMFT > 0 was highest in the 13-16 years age group (7.2 %). The mean pufa > 0 was highest in the 4-6 years age group (9.2 %). The overall caries prevalence was highest in the 4-6 years age group (17.4 %). Thirty-three percent of decayed teeth in the permanent dentition and 28.2 % of the primary dentition had signs of odontogenic infections. Despite the increase in the consumption of westernised diets by Nigerian children coupled with limited access to dental care, the prevalence was low but the clinical consequences of untreated dental caries was still high.

    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.

    Research has proliferated in recent years regarding the relationship of oral disease to systemic conditions. Specifically, periodontal disease has been studied as a potential risk factor for multiple conditions such as cardiovascular disease (CVD) and adverse pregnancy outcomes, while other research focuses on exposures or behaviors associated with oral disease. However, few articles have been published reporting how this information is integrated into schools of dentistry, both in the classroom and clinical curriculum. For our study, a thirty-three-item survey and cover letter were electronically mailed to academic deans at sixty-five accredited dental schools in the United States and Canada in the fall of 2007. The response rate was 77 percent. According to the responses to this survey, the primary topics covered in the didactic curriculum regarding periodontal oral-systemic disease are aging, CVD, diabetes, and tobacco use. Eighty-eight percent of the respondents reported that their students are knowledgeable about the role of inflammation and its impact on oral-systemic conditions. Forty-eight percent of the respondents said they provide formal training for their students in how to discuss or communicate aspects of periodontal oral-systemic disease with patients. Only seven schools reported teaching didactic content to dental students intermixed with other health professions students, and only two schools reported conducting joint projects. Only 9 percent of the respondents said they think nurses and physicians are knowledgeable about oral-systemic disease. The findings indicate that dental schools are confident about the knowledge of their students regarding oral-systemic content. However, much work is needed to educate dental students to work in a collaborative fashion with other health care providers to co-manage patients at risk for oral-systemic conditions.

    This study ascertained demographic information and prevalence rates of medical problems among 571 new and consecutive dental patients attending the emergency clinic of the School of Dentistry, The University of the West Indies. Patients were interviewed by specially trained and calibrated dental students and interns. Various medical problems of patients were recorded in individual open-ended case sheets, maintaining their privacy and confidentiality. This information was then transcribed into a specially designed and pretested form. The data were entered into a Microsoft Excel spreadsheet and analyzed using the SPSS statistical package to obtain the prevalence rates of medical conditions, which were then cross-tabulated with gender, age, ethnicity, and other variables. Significance of differences, if any, was evaluated by chi-square test. In all, 303 medical conditions were encountered in 239 individuals, giving a prevalence rate of 42 percent. Hypertension (12.6 percent), diabetes (6.1 percent), asthma (5.8 percent), arthritis (4.7 percent), and various allergies (8.3 percent) constituted an important segment of the problems. Gender, ethnic, and age differences were also evident for some diseases. In this study-which was the first of this kind in the West Indies-vital information on medical problems among dental patients was obtained by interviews conducted by dental students and interns, forming an important part of their dental education.

    According to a recent American Dental Association survey, posterior composite resin restorations now outnumber amalgam restorations in the United States. Dental schools around the world vary considerably in the extent to which they teach the use of composite resins. We aimed to determine if there has been an increase in the placement of posterior composite restorations in an Israeli dental school and if faculty experience affects the type of posterior restoration placed. In this retrospective study, we recorded and analyzed all the restorations performed by undergraduate students in the last five academic years at the Hebrew University Hadassah School of Dental Medicine in Jerusalem. All clinical records of student treatments between 2004 and 2009 were screened, and direct restorations were registered. Out of 6,094 posterior restorations performed during the study period, 42.3 percent were made of composite resin, increasing from 36.8 percent in 2004-05 to 48.5 percent in 2008-09, an increase of 11.7 percent. When clinical instructors were asked to state their preference if they themselves were to undergo posterior restoration, similar results were obtained. Instructors with less than ten years' experience preferred posterior composite resin restorations in 54.8 percent of the hypothetical situations, compared with 37.2 percent preferred by instructors with ten years of experience or more. It appears that the use of composite resin was influenced mainly by the prevailing trend and was not based on scientific evidence. Dental faculties should define criteria, based on up-to-date clinical studies, for using new materials, taking into consideration differences among instructors regarding treatment concept.

    2010-02-01

    With conflicting results in the literature and various manufacturer recommendations, it is not known what cementation protocols are currently being used for implant restorations in US dental schools. The purpose of this survey was to determine what dental cementation protocols are taught and recommended by 62 US dental schools and postgraduate programs. From February to September 2008, 96 questionnaires consisting of 8 questions were sent to the chairperson or director of restorative departments, advanced prosthodontics programs, and implant programs. The questionnaire asked recipients which implant manufacturers provided the products used at their dental schools. Additionally, recipients were queried as to the choice of material and techniques for abutment and restoration preparations prior to definitive cementation. Data were analyzed with descriptive statistics. A total of 68 (71%) surveys were returned, and 52 (84%) of the 62 predoctoral and postgraduate programs were represented. After deleting duplicate responses, 31 surveys were returned from restorative department chairpersons, 29 from advanced prosthodontic program directors, and 2 from implant program directors. Frequency of responses to each question was tabulated, and results are presented in 3 sections. For all 3 types of programs, Nobel Biocare was reported to be the most widely used implant system, followed by Biomet 3i, Straumann, Astra Tech, and Zimmer Dental systems. The most commonly used technique prior to definitive cementation is to airborne-particle abrade the intaglio surface of the restoration. Resin-modified glass ionomer is the most frequently used luting agent for cementing implant restorations. The 5 most commonly used materials to fill screw access openings are cotton pellets, composite resin, rubber-based material, gutta-percha, and light-polymerized provisional composite resin. Most predoctoral and postgraduate programs teach students to fill the screw access opening completely to

    Full Text Available Statement of Problem: Dilaceration is defined as a sudden change in the axial inclination of root or between the crown and the root of a tooth. There is no previous study evaluating its prevalence in south of Iran.Purpose: This study evaluates the prevalence of root dilaceration on the basis of its location in dental arch in a sample of dental patients referring to Shiraz dental school, Iran. Materials and Method: This retrospective study was performed using full mouth periapical radiographs of 250 patients who were referred to Shiraz dental school. Buccal and lingual dilaceration was determined by its known” bull’s eye” appearance in the radiographs or if the deviation was in the mesial or distal directions; the angle of 90 degree or greater between the deviation and the axis of root was the inclusion criteria. Results: Root dilaceration was detected in 0.3% of teeth and 7.2% of patients. It was distributed equally between the maxilla and mandible. Mandibular second molar was the most frequent dilacerated tooth (1.6% followed by maxillary first molar (1.3% and mandibular first molar (0.6%. The alveolar nerve was the most common anatomic structure near dilacerated teeth.Conclusion: According to this study, root dilaceration is an uncommon developmental anomaly which occurs mostly in the posterior teeth.

    Tooth-whitening using carbamide peroxide delivered in a custom-fitted tray (nightguard bleaching) is a relatively new procedure, yet it is currently one of the most commonly used types of esthetic dental treatment in private practice. This study determined the extent that nightguard bleaching (NGB) has been included in dental school curricula. All sixty-five dental schools in North America were surveyed about curriculum content and treatment protocol for the use of nightguard and other bleaching procedures, generating an 82 percent response. The survey covered eighteen subject areas related to NGB ranging from clinical requirements and indications to products and recall intervals used. The most commonly taught tooth-whitening procedure was NGB, which was most often taught by operative and restorative faculty. Although no schools had clinical requirements for NGB, 92 percent taught it. The most common indications for NGB were esthetic shade change and pre-restorative lightening of teeth. Unrestored caries, defective restorations, and pre-existing sensitivity were common contraindications. Most schools do not use a specific NGB consent form, but most use written patient instructions. Most schools use at least two different NGB products, bleach for two to four weeks, and use reservoired and scalloped trays. An average of 25 percent of NGB patients were estimated to develop sensitivity, for which treatment recommendations include fluoride, desensitizing toothpaste, and reduced exposure time. Curriculum time and safety concerns were reasons for not teaching NGB (8 percent schools). Most schools indicated that the relative importance of NGB in the curriculum was increasing.

    This article reports the results of a 2003 survey of medical emergency education taught in U.S. dental schools and compares the results to findings from surveys conducted in 1983 and 1992. A questionnaire was sent to the deans of all U.S. dental schools, requesting completion of the survey by the faculty member responsible for medical emergency education. Forty-three of fifty-four U.S. dental schools responded, and the data were compared to similar surveys conducted in 1983 and 1992. Special attention was given to changes in technology (pulse oximetry and automated external defibrillators), teaching methods (audiovisual, role-playing, and simulation), and subject matter (CPR, venipuncture, and endotracheal intubation) that affect medical emergency education. The study found a large disparity in number of hours dedicated to medical emergency training among dental schools. Surprisingly, CPR certification/recertification for both students and faculty was not provided at three of the reporting U.S. dental schools. Most schools included venipuncture and endotracheal intubation in their curriculum. Routine monitoring of vital signs remained fairly consistent over the past twenty years with a slight dip in the 1992 survey. A standardization of medical emergency education needs to take place to ensure an appropriate level of training for all dental students.

    2009-08-01

    This study was aimed at determining dental fluorosis prevalence and severity amongst 6-13-year-old students residing in Medellin, Colombia. A descriptive study was carried out on 1,330 students attending 34 public schools in the city of Medellin. Two dentists trained in dental fluorosis diagnosis performed the examinations were after the teeth had been brushed. Teeth were dried with gauze, isolated with cotton pellets and visually examined in natural light. The Thylstrup and Fejerskov index (TFI) was used for rating fluorosis. Dental fluorosis prevalence was 81 % (TFI>1); 46.4 % was related to mild dental fluorosis (TFI1 and TFI2) and 8.8% to severe dental fluorosis (TFI >5). TFI > or = 1 was found in 21 % of the children being examined in at least 50 % of their teeth. Dental fluorosis prevalence level was found to be high in Medellín, Colombia; health authorities should thus focus their attention on preventing this problem.

    This study was conducted to investigate the career history and perceptions about dental hygiene education programs among the alumni (1952-1999 graduates) of the School of Dental Hygiene in Tokyo Medical and Dental University. A questionnaire containing demographic, practice characteristics and views on the programs was mailed to 997 alumni in 1999, and 576 alumni (57.8%) responded. Three hundred and forty-one respondents worked as dental hygienists. The majority who responded were in clinical practice. One hundred and thirty-one of the respondents worked in private clinics, 76 in public health centers, and 72 in clinics in companies. The rate of them who worked in public health centers was much higher than the national average cited in the Statistical Report on Public Health Administration and Services. Two hundred and ninety-one respondents reported inadequate programs. The rate of them who reported inadequate programs was significantly higher in alumni who were working than in alumni who were not. The items cited as insufficiently taught at the school were clinical practice, instrumentation, foreign language, psychology, counseling, and nursing related subjects. Thus, many alumni suggested the need for better programs and continuing education. From these results, it was suggested that dental hygienists need to change their education programs in order to meet the present and future needs of more diversified society. This view was particularly prevalent among alumni who were working. The result showed that dental hygiene educators and dental hygienists urgently need to reconsider the professionalism of their field.

    The purpose of this study was to determine the predictive validity of preadmission scores on the performance of 131 students from nine successive classes at the Harvard School of Dental Medicine. The predictors included high school rank, SAT Verbal and Quantitative, selectivity of undergraduate college, college GPA, and DAT Academic, and PAT averages. The performance scores included science GPA, clinical GPA, oral examination scores, and scores on Parts I and II of the dental National Board examinations. Correlation coefficients were calculated between each predictor and performance measure. Only one was significantly greater than zero: DAT Academic average was positively related to Part II Board scores (r = .29). The apparent lack of validity of the other predictors was attributed to their restricted range.

    Introducción: los hábitos alimentarios saludables influyen sobre la salud oral. El tratamiento de la caries comprende la restauración dental con selladores y composites dentales, la mayoría con bisfenol A (BPA). Hipótesis: a) el desayuno y hábitos de higiene oral son factores importantes en el desarrollo de caries; b) el tratamiento de la caries con epoxirresinas conlleva riesgo de exposición oral a monómeros plásticos. Objetivo: relacionar la ingesta del desayuno y los hábitos de higiene oral con la caries dental y determinar la presencia de selladores/composites como fuentes potenciales de exposición al BPA. Métodos: se analizaron 582 niños/as en edad escolar de Granada (sur de España) de 7 años de edad (7,55 [0,64] años). Se empleó un cuestionario de frecuencia de consumo de alimentos, 3 recordatorios de 24 h y variables de estilo de vida, incluyendo la higiene bucodental. La calidad del desayuno fue estimada con el Breakfast Quality Index (BQI). Resultados: se detectó un 21,7% de caries. El valor medio del BQI fue 5,18 (1,29). El 24% de la población realizó un desayuno con alimentos ricos en azúcares simples (> 5% de la energía total), asociado significativamente con la frecuencia de caries en el análisis de regresión logística. El 35,8% de los participantes tomaron galletas; asociado significativamente con la frecuencia de caries. La ingesta de productos de panadería, cereales y lácteos mostró una asociación inversamente significativa con la frecuencia de caries. Conclusión: se necesitan más investigaciones para aclarar el papel de la dieta en la caries y el riesgo de exposición a xenobióticos estrogénicos, como el BPA.

    Full Text Available Introduction: The published literature on the prevalence of dental caries and fluorosis in Nalgonda district, an endemic fluoride belt in India was scanty. Objective: To determine the prevalence of dental caries and dental fluorosis among 12 and 15 years old school children in relation to fluoride concentration in Nalgonda district. Materials and Methods: Stratified random sampling technique was employed to select 20 schools from Nalgonda district. These areas were divided into four categories, low, medium, high and very high fluoride areas based on the fluoride concentration. The oral examination for dental caries and fluorosis among children who fulfilled the inclusion and exclusion criteria were conducted by a single trained and calibrated examiner using mouth mirror and CPI (Community Periodontal Index probe under natural daylight. The data analysis was done using Statistical Package for Social Sciences SPSS version 16. Results: The prevalence of dental caries among 12 and 15 year old school children was 42.6% and 48.6% respectively. The prevalence was more among females (56.9% than males (34.2%. The prevalence was more in low fluoride area (67% followed by very high fluoride area (56.1%. The lowest prevalence was in medium fluoride area (20.5%. The prevalence of dental fluorosis increased with increasing fluoride concentration with no difference in the gender and age distribution. Conclusion: Defluoridation of water in areas where the concentration of fluoride is more than optimal is an immediate need as dental fluorosis is a major public health problem in these areas.

    This review finds that college GPA and DAT scores provide dental schools in the United States and Canada with defensible methods for selecting students. College GPA seems the best predictor of academic performance in dental school. The academic average (AA) of the DAT is a better predictor than is the perceptual ability test (PAT), but dental educators who believe that evidence of manual dexterity or perceptual ability must be a part of the admissions decision can find enough supporting evidence to justify doing so. When added to college GPA and the AA, information from the PAT may in fact enhance predictability. There is also evidence, however, that manual skills can be learned during routine dental curricular experiences. Overall, conventional admissions criteria at best account for about 40 percent of the variance in dental school performance, and most of this variance occurs during the early years of the curriculum. Studies are lacking for evaluating criteria that may predict success in admitting students for preferentially addressing current challenges, including achieving diversity of the workforce, ensuring access to care for all, interprofessional health care, ethics and professionalism, filling faculty positions, and conducting needed research. Schools should periodically validate all of their admissions criteria against expected performances and make corresponding adjustments.

    This study compared the preference for learning styles of dental students in a small class in physiology at a South African university with the preference for teaching styles of the lecturers. It also analyzed and evaluated the teaching methods and aids the lecturers used. The study was done in the last teaching block of the year after students have been exposed to all the lecturing styles in the same premedical subject. Two separate questionnaires were used in the study in order to evaluate teaching methods and teaching media used by the lecturers and to measure the teaching methods and teaching media that students preferred. Through a critical analysis of the data, it was found that the students preferred cooperative and active teaching/learning experiences more than the lecturers are using them. The study emphasizes the importance of students being actively involved in the teaching-learning process through cooperative methods. This may enhance their ability to utilize cognitive skills such as creative thinking, interpretation, critical thinking, and problem-solving.

    The purpose of the study was to identify dental fluorosis prevalence and to analyze its association with tap water fluoride concentration and beverage consumption in school children from the city of Oaxaca, who were receiving fluoridated salt. A cross-sectional study was performed on elementary public school children. Dean's Index was applied to assess dental fluorosis. The parents of the children who were studied completed a questionnaire about socio-demographic characteristics and type of beverages consumed by their children. A total of 917 school children participated in this study. Dental fluorosis prevalence was 80.8%. The most frequent fluorosis category was very mild (41.0%), and 16.4% of the children were in the mild category. The mean water fluoride concentration was 0.43 ppm (±0.12). No association was detected between tap water fluoride concentration and fluorosis severity. The multinomial regression model showed an association among the mild fluorosis category and age (OR = 1.25, [95% CI 1.04, 1.50]) and better socio-economic status (OR = 1.78, [95% CI 1.21, 2.60]), controlling for fluoride concentration in water. Moderate and severe fluorosis were associated with soft drink consumption (OR = 2.26, [95% IC 1.01, 5.09]), controlling for age, socio-economic status, and water fluoride concentration. The prevalence of fluorosis was high. Mild fluorosis was associated with higher socio-economic status, while higher fluorosis severity was associated with soft drink consumption.

    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.

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.

    Full Text Available Introduction. The recent literature data points out a rising application of digital radiography - radiovisiography (RVG - in dental clinical practice. Objective. The aim of this study was to apply and compare RVG with the conventional radiographic technique (CRDG in terms of accuracy in linear measurement in dentistry. Methods. Measurements were done on the mandibular dogs teeth considering incisors crown width and height of the surrounding alveolar bone using RVG and CRDG. The control technique (CONT involved values obtained by direct gauging in dogs mouth. Each measuring was done by two examiners. Results. Considering the incisors’ crown width, there were no significant statistical difference in measurement using CRDG, RVG and CONT technique (p>0.01. Concerning the alveolar height gauging there were no significant difference in recorded values between the two radiographic techniques (p>0.01. The high level of inter-examiner agreement was observed for scoring in all techniques (CRDG, RVG and CONT. Conclusion. Although RVG did not expose more accuracy comparing to CRDG, having opulent tool service the first technique contributed more comfortable work during measuring procedures in this study.

    Shaping a clinical curriculum that is appropriate for novice dentists, is based on high-quality evidence of efficacy, yet reflects current practices is challenging. CAD/CAM units have been available to dentists since the late '80s. Recent improvements in the software, hardware and the clinical performance of available all-ceramic blocks have keyed a surge in interest. Based on a careful review of the systems available and, equally importantly, a review of the research regarding the longevity of reinforced glass ceramics, IUSD decided to add training on the use of the E4D CAD/CAM system to the curriculum. Students now receive lectures, preclinical hands-on training and clinical experience in fabricating all-ceramic restorations. At present any student who is interested in providing an all-ceramic restoration for his/her patient can do so using our CAD/CAM system. In a little less than one year our undergraduate dental students have provided 125 all-ceramic crowns to their patients. Clinical faculty have been impressed with the marginal fit and esthetics of the crowns. Finally, with students designing, milling, sintering and staining the restorations the CAD/CAM systems has reduced lab costs significantly.

    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.

    To assess the Prevalence and self perception of dental fluorosis among 15 - year old school children. A cross sectional study was conducted on 840, 15 - year old school children from 12 schools of Prakasam district. After taking informed consent from their parents or legal representatives, an interview was conducted using a pretested questionnaire to collect the data regarding self perception of dental fluorosis, dental behaviour, and source of water and diet and socio demographic characters. Oral examination was done under natural light to score Deans fluorosis index. Statistical test used was chisquare test. Study revealed that 82.04% of the study population were having dental fluorosis. Out of which only 42.3% were aware of the existing situations. 47.90% of boys are aware of dental fluorosis where as 40.50% of girls are aware of dental fluorosis. Fluorosis score in relation to gender is not statistically significant (chisquare (8.796);p=0.117). Dental fluorosis is a public health problem in Kanigiri town. As there was no study conducted in Kanigiri town even though it is one of the severely affected area in our country. Active steps must be taken to De fluoridate the water before distribution to reduce the morbidity associated with dental fluorosis in this area.

    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.

    1999-01-01

    Dental caries is becoming increasingly common in developing countries but very few attempts have been made to assess its prevalence accurately. We therefore carried out an epidemiological survey in 1998 in the south of Benin, to estimate the prevalence of dental caries in 300 school children, both boys and girls, aged 12 to 14 years. Each child underwent a dental examination and interview and the data obtained were recorded in a personal clinical record. We determined DMF index for various subgroups of children. We then analyzed DMF index and its correlation with sex, age, socioeconomic level, the urban or rural origin of the child, diet and daily dental hygiene practices. We found that mean DMF index at age 12 years was 0.83 (38.7% had dental caries and 4.4% had fillings), and thus, 61. 3% of the children were free of dental caries. We also found that 80% of the children had an accumulation of tartar. More boys than girls had dental caries. Rural children were less likely to have dental caries than urban children. The prevalence of caries appears to be low despite poor dental hygiene and a lack of dental treatment. These results conflict with those of most other studies. However, they should be interpreted with caution because the population studied was very homogeneous (selection bias), the age of the children could be no more than approximate (some were probably younger than 12 and others older than 14, because the registry system is inaccurate), there had been health education classes in some schools before the survey and it was difficult to define socioeconomic level and a sugary diet. For example, the lower socioeconomic level (no TV, radio, electricity or tap water) was probably an accurate representation of children from the rural area, whereas urban children were proud of being well-equipped and may have had a tendency to exaggerate. The prevalence of dental caries in this population is currently as low as that for most pre-industrial African countries. To

    Successful integration of critical thinking and evidence-based dentistry (EBD) concepts throughout didactic and clinical dental curricula require faculty support. Critical thinking and EBD definitions and practice continue to evolve, and not all dental faculty members were exposed to such concepts during their education. The objective of this study was to understand faculty members' perspectives on both critical thinking and EBD. An online survey was designed to assess full- and part-time faculty members' understanding, practice and teaching of critical thinking and EBD, interest in and perceived significance of EBD, and perceived barriers to teaching critical thinking and EBD at one U.S. dental school. Forty-three faculty members completed the survey for a 41 percent response rate. Most respondents (46 percent) defined critical thinking as the use of evidence or the scientific method in decision making and EBD as clinical practice based on "science only" (39 percent) or "quality science only" (34 percent). Based on their individual definitions, over 75 percent of the respondents reported incorporating critical thinking into didactic and clinical teaching; 79 percent and 47 percent, respectively, reported incorporating EBD into their didactic and clinical teaching. While these faculty members confirmed the importance of teaching students EBD, they identified barriers to teaching as time, knowledge, and resources. These results, which reflect one school's efforts to understand faculty perceptions and practices of EBD, suggest that faculty training and resource support are necessary for successful curricular integration of critical thinking and EBD.

    The severity of dental mottling in 2,592 school-aged, lifetime residents of 16 Texas communities was investigated in 1980-81 to identify factors associated with mottling and to construct a prediction model for the prevalence of mottling. The communities were selected to obtain a wide range of levels of fluoride in the drinking water. The children within each of the communities were contacted through their schools and received a dental examination to assess the severity of mottling. Information on demographic, dental health practice, and other candidate predictor variables was obtained from a questionnaire completed by a parent. A number of water quality measurements were also recorded for each community. White and Spanish-surname children had about the same prevalence of mottling while Blacks had a higher prevalence, odds ratio (OR) = 2.3, 95% confidence interval = 1.4, 3.7. Children from homes which had air conditioning had a lower prevalence of mottling (OR = .6, (0.4, 0.8)). The use of fluoride toothpaste or drops and the number of fluoride treatments were almost identical among those who did and did not develop moderate mottling. In addition to fluoride, total dissolved solids and zinc were water quality variables associated with mottling. PMID:4061713

    Dental wastes are regulated under medical waste control regulations in most countries. Even though the quantity of hazardous wastes in dental solid wastes is a small proportion, there is still cross infection risk and potential danger for environment associated with mismanaged wastes. For this reason, knowledge of waste composition and development of proper management alternatives are necessary. In this study, the composition of solid wastes coming from eight clinics of the dental school of a University hospital in Turkey is examined. Although the waste has some variations between the two samplings, the general picture is such that the major components remain pretty much the same (in terms of %) for a fixed clinic. The composition of waste changes from one clinic to the other as expected. However, one can deduce from the data obtained that at about 35%, rubber gloves constitute close to the half of the total solid waste in almost all the clinics. Other major component is paper forming approximately 30% of the solid waste. In general, total waste coming from the clinics is related with the number of procedures conducted on patients at the clinics. Only a small fraction of the waste is hazardous indicating that at Hacettepe University School of Dentistry, hazardous waste collection rules are obeyed in most of the times.

    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.

    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.

    Full Text Available Objective: Excessive weight in children is a major public health concern. The intake of refined carbohydrates, especially sugars and the prevalence of dental caries are well documented in the literature. The purpose of this study was to investigate the relationship between dental caries and BMI in elementary school children.Materials and Methods: The sampling technique used in the present study was a cluster random sampling. A total of 1000 pupils (500 girls, 500 boys aged 6-11 years from 20 private and state elementary schools (10 boys, 10 girls. The weight status was measured in children by assessment of body mass index (BMI (=bodyweight/body height2 kg/m2 corresponding to gender and age-ranked percentages.To assess the caries frequency the decayed filled teeth (DFT index for permanent dentition and the dft index for primary dentition were used since they give good perception about the situation of tooth caries in young patients.Results: The highest mean total dft/DFT was seen in normal weight and lowest average in at risk of overweight children. There was not a statistically significant relationship found between high weight and caries frequency in the first (p=0.08 and permanent dentitions (p=0.06.Conclusion: The results of this preliminary study do not support an association between dental caries and obesity.

    Objective: Among dental diseases, dental caries is an important dental public health problem in India which is irreversible in nature, and is predominantly a disease of childhood. Till date no study has been carried out in Vadodara. As baseline data of caries is required to improve oral health of children, the present study was undertaken to determine the pattern of dental caries in school children of Vadodara city in the mixed dentition period considering age, sex and dietary patterns. Methods: An epidemiological cross sectional descriptive study was carried out among 1600 school children aged 6-12 years in Vadodara city. A closed ended questionnaire according to World Health Organisation 1997 methodology was used to collect the data. The children were examined for the presence of dental caries using decayed missing filled teeth/decayed missing filled surfaces and Decayed Missing Filled Teeth/Decayed Missing Filled Surfaces index. Related factors which predispose caries such as age, sex and dietary patterns were recorded. Results: The prevalence of dental caries was 69.12%. The mean dmft/dmfs and DMFT/DMFS were 3.00/4.79 and 0.45/0.56 respectively. The prevalence was higher in deciduous teeth than in permanent teeth. Positive association was found between dental caries and age, sex, frequency of sugar consumption in between meals. Conclusion: The study concludes that the prevalence and severity of dental caries in Vadodara city is high. So, in developing country like India, it is imperative to introduce primary prevention and increased restorative care for the purpose of both reducing the caries prevalence and maintaining those caries free children.

    Fluorosis can manifest as dental fluorosis (seen mostly in secondary dentition), skeletal fluorosis, and systemic fluorosis. Groundwater with high fluoride concentrations, diet rich in fish and tea, indoor air-pollution, and use of fluoride toothpastes may contribute considerably to total exposure. To assess the prevalence of dental fluorosis and associated factors particularly fluoridated toothpastes, among middle school children of a resettlement colony in Delhi. This survey was conducted among the middle school students (VI th -VIII th ) studying in three government schools of Sangam Vihar, South Delhi. Students were examined for dental fluorosis by experts. A pre-structured questionnaire was used to obtain data regarding age, source of drinking water, toothpaste used, etc. Height, weight, and hemoglobin were recorded. Two repeat visits were made. Out of 432 students enrolled in these schools, 413 students were examined. Descriptive and chi-square statistics were used. Dental fluorosis was prevalent in 121 (29.3%) study subjects. It was significantly more in children of age 13 years or above, in those who used fluoridated toothpaste for dental cleaning (P=0.033) and in anemic children (Pfluorosis is very common (in about one-fourth) among the middle school children, in this resettlement colony of Delhi, various control measures e.g. discouraging the fluoridated toothpastes, educating parents about fluorosis, de-fluoridation of water in the high risk areas, etc may help to tackle this situation.

    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. 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 children. More children living in urban area were detected with gingivitis (p dental caries than children residing in rural areas. Incidence of gingivitis (p dental caries in primary (p children who were not brushing their teeth. Experience of dental caries in primary teeth was found higher (p 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.

    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.

    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. Cross-sectional study. Government and private schools of Quetta, from November 2012 to February 2013. Atotal 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. Dental caries was found in 81 children (23.2%) with mean DMFT0.61. Boys had 1.6 times more chance to have dental caries than girls. Dental fluorosis was found in 63.6% of children with majority of moderate degree (50.5%). 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. 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.

    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.

    Quality assurance (QA) and risk management (RM) programs are intended to improve patient care, meet accreditation standards, and ensure compliance with liability insurance policies. The purpose of this project was to obtain and disseminate information on whether dental schools integrate QA and RM and what mechanisms have been most effective in measuring accomplishments in these programs. All sixty-five U.S. and Canadian dental schools were sent a twenty-nine-item survey, and forty-six (71 percent) schools responded. The main findings are as follows: 66 percent had a written QA program combined with a QA committee; 95 percent received administrative support; there was wide variation in the makeup of the QA committee; many institutions reported significant changes resulting from the QA program; and over half of the respondents merged QA and RM in some fashion. To develop or maintain an effective QA/RM program, the authors propose the following: obtain active support from the dean; develop goals and mission/vision statements; include trained personnel on the committee; establish wide levels of involvement in the QA program; develop QA measurements to ensure compliance with institutionally developed standards of patient care; and establish continuous cycles of improvement.

    North American dental schools were surveyed to determine the types of clinical experiences and the extent of material use that predoctoral students encounter with restorative procedures that employ all-ceramic materials. The results were based on an overall response rate of 80% from the 64 surveyed schools. The majority (96%) of the 51 schools responding to the survey did offer an opportunity to become experienced with all-ceramic restorations. The selection of bases and liners for all-ceramic restorations included dentin adhesive agents, glass ionomer materials, and calcium hydroxide products, by a ratio of 5:4:1, respectively. The most commonly used impression material types were addition silicone and polyether. One or both of these materials were used by every school. Dicor glass ceramic and alumina core ceramic were the most commonly used materials by the responding schools for veneers, onlays, and crowns. Dicor glass ceramic and CAD/CAM ceramic were most commonly used for inlays. Crowns were made of more different all-ceramic material types than the other restoration classes. Fabrication of all-ceramic restorations was primarily by commercial laboratories and school technicians. Students have hands-on experience in the fabrication of all-ceramic restorations in 6% of the responding schools. Luting agents for all-ceramic restorations include dual-cured resin, in 96% of the responding schools, light-cured resin, 43%, and glass ionomer cement, 33%. Zinc phosphate, chemical-cured composite, and polycarboxylate were used by less than one fourth of the respondents. Only resin-based composite materials were used to lute ceramic veneers. Rubber dam was applied primarily during luting procedures involving all-ceramic inlays and onlays. Crowns and veneers were isolated by this method in less than 30% of the responding schools. Finishing procedures with all-ceramic restorations were accomplished with three or more instruments by 89% of the schools.

The study subjects were students (42 UOD and 30 KSU, patients (32 UOD and 46 KSU, and faculty members (8 UOD and 7 KSU. Evaluations were collected using self-administered surveys. Results: The response rates were 72%, 78%, and 32% for students, patients, and faculty members, respectively. The students′ evaluations demonstrated that case acceptance by supervisors was one of the difficulties facing 57.14% of UOD students compared to 30% of KSU students. The majority of faculty members (39% were restorative specialists (25% UOD, 42.86% KSU. The overall evaluation of UOD faculty members was fair (50% or good to very good (50%. For KSU faculty members, the overall evaluation was good (50% or very good (50%. The mean age of the patients was 33.26 years. The level of education of the study subjects was either secondary school (43.6% or university level (35.9%. Most of the study subjects knew about the program from their friends (57.7%. Approximately 96.1% of the study subjects were satisfied with the overall treatment of students. Discussion: The fundamental aim of the students was to have their cases accepted as early as possible to complete requirements on time. Conclusion: Dental students displayed relatively high psychological stress in relation to case acceptance by their supervisors. Demonstrating good attitude and quality treatment can increase the flow of patients.

    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 practice consists of a series of laboring procedures which demands the use of several types of equipment and materials. Usually patient"s fears brings additional burden to the Dentists. The use of Lasers for treating and diagnosis in Dentistry is quite new comparing to other medical areas. Initially Laser technology was used as an alternative method for treating dental caries in order to substitute the use of the drill. Lately surgical Lasers have shown themselves very useful for treating several pathologies and began to be used as a powerful tool on the treatment of several conditions affecting the maxillofacial complex and later on, the era of the use of Laser therapy began. The advent of the diode Lasers made possible the introduction of small units at the dental office and Laser therapy was used to improve healing and later included also caries diagnosis. This paper discuss the use of Laser therapy on Restorative Dentistry, Periodondology, Oral and Maxillofacial Surgery, Oral implantology and other. Clinical and laboratorial experience has demonstrated that Laser therapy does improve the healing of both mineralized and soft tissues, reduces pain and inflammation, and also reduces both cost and length of the dental treatment.

  17. Dental school faculty and the academic environment from 1936 to 2011: familiar features in a new context.

    From its first issue in 1936 until today, no subject has been more central to the work published in the Journal of Dental Education (JDE) and to dental education itself than the dental school faculty. William Gies's vision in 1926 of the professionalization of dental educators was key to the professionalization of dental education. His focus on the need to develop these teachers as both instructors and researchers established the model by which a "dental educator" became a distinct professional, different from a dentist who happens to teach. This article for the seventy-fifth anniversary issue of the JDE thus starts from the obvious but not always acknowledged point that faculty members are central to the entire enterprise of dental education and relate to change over time as both cause and effect. Whether the profession today is evolving to incorporate new science and curricular models or becoming more interprofessional or meeting the needs of diverse patient populations or adopting new educational methodologies and technologies, developments in these areas will have a direct impact on the way individual faculty members do their jobs. To give a taste of the rich variety published over the past seventy-five years, the first section touches briefly on three significant types of research regarding faculty as exemplified by articles published in the JDE. These three are faculty development, educational methodologies, and faculty recruitment and retention. The second section addresses an increasingly important area of research: faculty members' perceptions of the academic work environment. After considering some trends that will affect this environment over the next decade, the article concludes with additional reasons the JDE is a valuable resource for faculty members in dental schools and allied and advanced dental education programs.

    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.

    There was only one dental school in Malaysia until 1997 but five new schools have been established since 1998. This review provides information about dental education in Malaysia including; the history of dental education, the current dental school system and curriculum, and dental licensure. There are four public and two private dental schools in Malaysia. High school graduates are required to take the nationwide matriculation entrance examination or the Higher School Certificate (HSC) to apply for a dental degree programme. A five-year dental programme leads to the BDS or the DDS degree. National or state examinations are not required to practise dentistry. Currently, there are approximately 2,500 dentists, with a ratio of 1 dentist for every 10,000 people.

  3. Extracellular matrix of dental pulp stem cells: Applications in pulp tissue engineering using somatic MSCs

    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.

    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 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.

    The noise levels made by different clinical handpieces and laboratory engines are considered to be the main descriptors of acoustical comfort in learning spaces in a dental medicine school. Sound levels were measured in five types of classrooms and teaching laboratories at the University of Porto Dental Medicine School. Handpiece noise measurements were made while instruments were running free and during operations with cutting tools (tooth, metal, and acrylic). Noise levels were determined using a precision sound level meter, which was positioned at ear level and also at one-meter distance from the operator. Some of the handpieces were brand new and the others had a few years of use. The sound levels encountered were between 60 and 99 dB(A) and were compared with the noise limits in A-weighted sound pressure level for mechanical equipments installed in educational buildings included in the Portuguese Noise Code and in other European countries codes. The daily personal noise exposure levels (LEP,d) of the students and professors were calculated to be between 85 and 90 dB(A) and were compared with the European legal limits. Some noise limits for this type of environment are proposed and suggestions for the improvement of the acoustical environment are given.

    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

    Full Text Available Introduction: Fluorosis can manifest as dental fluorosis (seen mostly in secondary dentition, skeletal fluorosis, and systemic fluorosis. Groundwater with high fluoride concentrations, diet rich in fish and tea, indoor air-pollution, and use of fluoride toothpastes may contribute considerably to total exposure. Objective: To assess the prevalence of dental fluorosis and associated factors particularly fluoridated toothpastes, among middle school children of a resettlement colony in Delhi. Materials and Methods: This survey was conducted among the middle school students (VI th -VIII th studying in three government schools of Sangam Vihar, South Delhi. Students were examined for dental fluorosis by experts. A pre-structured questionnaire was used to obtain data regarding age, source of drinking water, toothpaste used, etc. Height, weight, and hemoglobin were recorded. Two repeat visits were made. Out of 432 students enrolled in these schools, 413 students were examined. Statistics: Descriptive and chi-square statistics were used. Results: Dental fluorosis was prevalent in 121 (29.3% study subjects. It was significantly more in children of age 13 years or above, in those who used fluoridated toothpaste for dental cleaning (P=0.033 and in anemic children (P<0.001. However, there was no significant association of disease with gender (P=0.02, source of drinking water (P=0.417, and with BMI (P=0.826. Conclusion: As dental fluorosis is very common (in about one-fourth among the middle school children, in this resettlement colony of Delhi, various control measures e.g. discouraging the fluoridated toothpastes, educating parents about fluorosis, de-fluoridation of water in the high risk areas, etc may help to tackle this situation.

    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.

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

    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."

    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. 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. 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). 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. 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 parts per million and above as dental fluorosis is a public

    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

    It is demonstrated that carboxylic acid-functionalized titanium dioxide (TiO2) NPs produce significantly higher levels of reactive oxygen species (ROS) after visible light irradiation (400-800nm, 1600mW/cm(2)) in comparison to nonfunctionalized TiO2 NPs. The level of ROS produced under these irradiation conditions was not capable of generating oxidatively induced DNA damage in a cell-free system for TiO2 concentrations of 0.5mg/L or 5mg/L. In addition, specific incorporation of the acrylic acid-functionalized TiO2 NPs into dental composites allowed us to utilize the generated ROS to enhance photopolymerization (curing and degree of vinyl conversion (DC)) of resin adhesives and create mechanically superior and biocompatible materials for dental applications. Incorporation of the TiO2 NPs into selected dental composites increased the mean DC values by ≈7%. The modified TiO2 materials and dental composite materials were extensively characterized using thermogravimetric analysis, electron microscopy, Fourier transform infrared spectroscopy, and electron paramagnetic resonance. Notably, dental adhesives incorporated with acrylic acid-functionalized TiO2 NPs produced stronger bonds to human teeth following visible light curing in comparison to traditional dental adhesives not containing NPs with an increase in the shear bond strength of ≈29%. In addition, no leaching of the incorporated NPs was detectable from the dental adhesives after 2500 thermal cycles using inductively coupled plasma-optical emission spectroscopy, indicating that biocompatibility of the adhesives was not compromised after extensive aging. These findings suggest that NP-induced ROS may be useful to produce enhanced nanocomposite materials for selected applications in the medical device field. Titanium dioxide nanoparticles (TiO2 NPs) have unique photocatalytic, antibacterial and UV-absorbing properties that make them beneficial additives in adhesives and composites. However, there is concern that

    Objectives: Age estimation plays an important role in forensic medicine and orthodontics. Many methods of age estimation have been suggested. Demirjian method is the most frequently used one of these. In the literature, there is a little known about applicability of this method in Turkish children. The aim of the present study was to evaluate the reliability of Demirjian method of dental age estimaiton and for description of mandibular permanent tooth formation in Turkish children from the southwest Eastern Anatolia region.

    Materials and Methods: A retrospective study was performed on 1015 panoramic radiographs and 5-15 years of age South western of Eastern Anatolia Regionof Turkish children. The stages of dental maturity of the mandibular left seven permanent teeth for each subject using the eight radiographic dental maturity stages demonstrated by Demirjian’s method were evaluated. A pired t-test was used for statistical analysis.

    Results: The mean difference between the chronological and dental ages ranged 0,28 to 1,10 years in boys and from 0,18 to 0,68 years in girls. South western of Eastern Anatolia Region ofTurkish children were generally delayed in dental maturity compared with children in Demirjian sample. The differences between the chronological and dental ages were statistically significant in 6-6.9, 8-8.9, 9-9.9, 10-10.9, 11-11.9 years in boys and in 8-8.9, 9-9.9,11-11.9 years in girls.

    Conclusions: Turkish children from the southwest Eastern Anatolia region are significantly more delayed in dental maturity compared to Demirjian’s French-Canadian sample. The applicability of Demirjian data is not suitable for Southwestern of Eastern Anatolia Region of Turkish children.

    Full Text Available The additive technologies characterize with the building of one layer at a time from a powder or liquid that is bonded by means of melting, fusing or polymerization. They offer a number of advantages over traditional methods: production of complex personalized objects without the need of complex machinery; manufacturing of parts with dense as well as the porous structure and predetermined surface roughness; controllable, easy and relatively quick process. The methods, mostly used in prosthetic dentistry, include stereolithography, selective laser sintering, and selective laser melting. The aim of the present paper is to review the features of the Selective Laser Melting (SLM process and the possibilities of its application for production of fixed dental prostheses. The features of the SLM process, the microstructure and mechanical characteristics of dental alloys as well as the properties of fixed dental prostheses, fabricated via SLM, were discussed. It was revealed that the SLM Co-Cr dental alloys possess higher mechanical and tribo-corrosion properties, comparatively good fitting ability and higher adhesion strength of the porcelain comparing to the cast alloys. All this is a good precondition for successful application of the SLM process in the production of fixed dental prostheses, mainly of frameworks for metal-ceramic and constructions covered with polymer/composite, intended for areas with high loading.

    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.

Questionnaires regarding the undergraduate teaching related to head/brain injuries were sent to, and returned by, all 12 UK dental schools. The replies suggest that undergraduate teaching of this subject is patchy and inadequately prepares dentists to recognise and cope with patients who may have had head, and consequently brain, injuries. It is recommended that dental schools review their teaching of this subject and ensure that it is consistent with the current guidelines issued by the National Institute of Clinical Excellence (NICE) on the recognition of head injury and that the findings are brought to the attention of the General Dental Council in the context of the GDC's "The first five years" report.

    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. 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. 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 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. 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 associated with the condition in the study region.

    A survey was conducted of 100 dental schools worldwide to investigate the current teaching of posterior resin composite restorations. A 20 multi-part question questionnaire was emailed to the selected schools. Schools were selected by ability to understand and respond in English. The questionnaire consisted of four open-ended questions and 16 closed questions on topics such as material selection for restoring posterior teeth, preclinical teaching of resin composite for posterior teeth, restoration size, contraindications, matrix placement methods, lining use, adhesive selection and finishing. Forty-six schools responded. The outcomes showed all schools included the teaching of resin composite for posterior restorations but varied. The majority of schools (63%) no longer taught amalgam as the preferred posterior restorative material. Half of the schools surveyed set numerical clinical requirements for restoration placement. Australian schools had no requirements whilst 92% of Asian schools did. There was a consensus that larger restorations were less suitable for resin composite. Selection of adhesives depended on region. Generally, the schools surveyed showed minor variations philosophically in teaching of the use and placement of resin composite restorations. © 2011 FDI World Dental Federation.

    This study sought to provide an overview of current cariology education in Spanish-speaking Latin American dental schools. Data collection was via an eighteen-item survey with questions about curriculum, methods of diagnosis and treatment, and instructors' perceptions about cariology teaching. The response rate was 62.1 percent (n=54), and distribution of participating schools by country was as follows: Bolivia (four), Chile (four), Colombia (twenty-four), Costa Rica (one), Cuba (one), Dominican Republic (two), El Salvador (two), Mexico (six), Panama (two), Peru (four), Puerto Rico (one), Uruguay (two), and Venezuela (one). Forty percent of the responding schools considered cariology the key axis of a course, with a cariology department in 16.7 percent. All schools reported teaching cariology, but with varying hours and at varying times in the curriculum, and 77.8 percent reported having preclinical practices. The majority reported teaching most main teaching topics, except for behavioral sciences, microbiology, saliva and systemic diseases, caries-risk factors, root caries, erosion, and early caries management strategies. The most frequently taught caries detection methods were visual-tactile (96.3 percent), radiographic (92.6 percent), and the International Caries Detection and Assessment System (ICDAS) (61.1 percent). Respondents said their schools' clinics make an operative treatment decision when radiolucency is in the inner half of enamel (42.3 percent) for radiographic criteria and when the lesion is visually non-cavitated (5.8 percent). All respondents reported that their schools teach preventive strategies, but only 43.4 percent said they tie it to risk assessment and 40.7 percent said they implement nonsurgical management regularly.

    A new method of dental introscopy in-vitro is suggested by the authors. This method implies the usage of longitudinal tomography techniques and is characterized by non-invasive and non-harmful diagnostics features, as well as interactive regime of image reconstruction which lets an operator (doctor) to control the diagnostics process in real time. He-Ne laser emission is used for obtaining of the projections. By the means of longitudinal tomography, images of different sections of an object (tooth) can be reconstructed. An experiment was held by the authors in which 100 projections of a tooth (premolar) were obtained and images of 10 different sections were reconstructed. These images were later compared to real sections of the tooth. This experiment proved that optical longitudinal tomography can be successfully used for dental introscopy. Authors claim that optical tomographic methods can be used for diagnostics of other biological objects as well. Such objects are characterized by spatial geometrical anisotropy (tubular bones, phalanxes of fingers, penis, etc.). It is especially promising to use this method for children's dentistry. the authors discuss some features of the data acquisition system for optical longitudinal tomography. Reconstruction algorithms are described. The results of experimental reconstruction are presented and advantages of this diagnostics method are discussed.

    In clinical practice, self-efficacy refers to how certain a patient feels about his or her ability to take the necessary action to improve the indicators and maintenance of health. It is assumed that the prognosis for patient behaviour can be improved by assessing the proficiency of their self-efficacy through providing psychoeducational instructions adapted for individual patients, and promoting behavioural change for self-care. Therefore, accurate assessment of self-efficacy is an important key in daily clinical preventive care. The previous research showed that the self-efficacy scale scores predicted patient behaviour in periodontal patients and mother's behaviour in paediatric dental practice. Self-efficacy belief is constructed from four principal sources of information: enactive mastery experience, vicarious experience, verbal persuasion, and physiological and affective states. Thus, self-efficacy can be enhanced by the intervention exploiting these sources. The previous studies revealed that behavioural interventions to enhance self-efficacy improved oral-care behaviour of patients. Therefore, assessment and enhancement of oral-care specific self-efficacy is important to promote behaviour modification in clinical dental practice. However, more researches are needed to evaluate the suitability of the intervention method.

    This investigation studied the dental health status of a group of 184 Australian Aboriginal children with a mean age of 4.4 +/- 0.8 years, who were attending pre-schools in metropolitan Brisbane, a non-fluoridated state capital city. The DDE (Developmental Defects of Enamel) Index was used to chart enamel hypoplasia and enamel opacities. WHO criteria was used to diagnose dental caries. The results showed that 98% of children had at least one tooth showing developmental enamel defects. Each child had a mean of 3.8 +/- 1.7 teeth affected by enamel hypoplasia and another 1.1 +/- 0.8 teeth affected by enamel opacity. Seventy-eight percent of the children had dental caries. The mean number of decayed, missing, filled teeth (dmft) per child was 3.8 +/- 3.7. The decayed component constituted 3.5 (95%) of the mean dmft, indicating a high unmet restorative need in this group. The mean dmfs (decayed, missing, filled, surfaces) was 5.9 +/- 7.3. Maxillary anterior labial decay of at least one tooth affected 43 (23%) of the children. In this sub-group, the dmft and dmfs was 9.1 +/- 2.8 and 15.4 +/- 7.7 respectively. Oral debris was found in 98% of the children. It is hypothesized that the high levels of underlying developmental enamel defects, compounded by low fluoride exposure, poor oral hygiene and a diet high in refined sugars pose an important caries risk factor in this group of children.

    Full Text Available Introduction: Very few studies have documented the relative significant factors that assess the parents and their family status that can have some impact towards dental treatment needs. Aim: To assess the burden of dental caries among children aged 8-14 years in relation to parental influence and family characteristics from North Bengaluru. Materials and Methods: A cross-sectional epidemiological survey was carried out on 1216 school children aged 8 years to 14 years. Children were examined in schools and data comprised information about dental caries status. Structured questionnaires were given to parents to collect information regarding their socioenvironmental and family characteristics. Student′s t-test on metric parameters and Chi-square/Fisher for study parameters between two or more groups were used. Results: In families where the average monthly income <6000/-, decayed, missing, and filled teeth was proportionately lower in comparison to decayed, missing, and filled surfaces which were higher. Conclusions: The socioeconomic status, which is primarily influenced by parental factors and family structure, have a definite role in dental needs of children from underprivileged background. Dental health program should aim to reduce the gross inequalities in the oral health status of these children and their families.

    Dental fluorosis is a dental tissue disease, characterized by hypomineralization resulting from excess fluoride reaching the developing tooth. In Mexico in recent years, the prevalence of fluorosis has increased by the exposure to different fluoridated sources such as those found in soft drinks and beverages. Our objective was to determine the prevalence of dental fluorosis among school children living in Nezahualcoyotl, state of Mexico and identify associated risk factors. We conducted a cross-sectional study among 455 children aged 6-13 years who had been assessed by a previously standardized observer following WHO criteria. We administered The Community Fluorosis index (FCI) and a survey that analyzed the exposure to fluorides hidden in carbonated drinks, juices, bottled water, tea and the use of fluoride toothpastes. The prevalence of dental fluorosis was 73.4%. Very mild and mild fluorosis were the more common levels. The Community Fluorosis index (ICF) was 1.18 +/- 0.80. School children living at Nezahualcoyotl that answered they did drink hidden fluorides > 0.71 ppm thought bottled beverages were more of a risk to develop dental fluorosis (RM 1,554, 95% CI 1.016-2.378, pfluorosis results from fluoride intake by different sources, however our study, consumption of fluoride hidden in soft and bottled drinks showed a significant correlation with observed fluorosis.

    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.

    The luminous plasma generated during laser ablation of dental tissue and dental materials has been analyzed to determine qualitative and quantitative elemental composition. The use of pulsed lasers for controlled material ablation now is frequently suggested as an alternative to mechanical drilling for the removal of caries and in tooth modification. Spectral analysis of the ablated plasma can be exploited to monitor precisely the laser drilling process in vivo and in real time. Teeth samples and dental materials were ablated using pulses from a Nd:YAG laser. The line positions and intensities in the spectra, recorded in real time, were used to identify elements and to determine their relative concentrations. From the spectra of horizontally and vertically cut tooth slices, profiles of elemental distribution were determined; these were used in a range of monitoring applications. We showed that the transition from caries to healthy tooth material could be identified through the decrease in calcium (Ca) and phosphorus (P) concentrations, whereas nonmineralizing elements and organic materials increased in concentration. We also could relate the spatial distribution of elements to their migration or accumulation over time, for example, the migration of aluminium (Al) from dental restorative materials to the tooth matrix. The plasma existing during laser ablation (in vitro/in vivo) can be analyzed spectrally in real time. From the spectra, one can pinpoint high/low levels of element concentrations within the tooth matrix. Thus, this analysis could be used to monitor the ablation of material during laser dental treatment.

    Whereas replacement of failed restorations is the major treatment for adults in dental practice, repair is an important alternative with the potential to save tooth structure and increase the longevity of restorations at a lower cost. This in vitro study recorded the choices of treatment for the same set of teeth with defective Class II amalgam restorations by students and faculty at two dental schools (University of Manchester, UK and University of Florida, USA). Treatment options (monitor, refurbish, repair and replace) and reason(s) for the choice of treatment for 24 marked amalgam restorations were selected. Overall, participants more frequently chose replacement of restorations; whereas, repair was the least favored option. The reasons cited the most to replace restorations were secondary caries including unsightly appearance, partially lost restoration and tooth fracture; for repair, the major reasons included loss of part of the restoration and marginal ditching; and for refurbishment, the major reasons included poor anatomic form and marginal ditching. There was a significant difference between the students and faculties at the two sites in their choice of treatment (p<0.0001; Chi-square test). The treatment decision to "monitor" the restorations was more frequent for the Manchester site than the Florida site. Conversely, the combined treatment decisions to "refurbish, repair and replace" were more frequently chosen in Florida than in Manchester.

    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.

    Introduction: The use of lasers has become a practice in modern periodontology and it is a fact that the use of diodes in the dental office can bring a real benefit in periodontal surgery. Material and method: These case reports describe few of various soft tissue procedures that were performed with diode laser 940 nm (Epic 10, Biolase Inc., USA). Discussions: There are a few immediate benefits of the intervention: the "periodontal bandage" belongs to the patient, the procedure is painless, performed under a superficial anesthesia and the psychological impact on the patient, as well as the acceptance, are superior to conventional methods of dentistry. Conclusions: Diode lasers at the level of periodontium have become a significant part of the dentistry, reducing the patient's stress and giving satisfaction to practitioners as well.

    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.

Methodology: Four hundred and twelve secondary school adolescents were assessed using interviewer-administered questionnaire. Data on dental care knowledge and practice obtained through the questionnaire were analyzed using descriptive and inferential statistics with level of significance set at 5%. Result: Consumption of sticky, sugary and chocolaty food items was perceived by a majority (81.8% as unhealthy to dental health and 66.3% perceived consumption of fruits and vegetables as healthy to the teeth. Vertical brushing technique was mentioned by 69.7% of respondents as the best method of brushing the teeth, and 89.6% stated that teeth should be brushed twice daily. Majority 57.0% of respondents open caps of soft drink bottles with their teeth and 74.3% used toothpicks to remove food trapped in between teeth. Majority (82.8% perceived that dentist should be visited for check-up once in 6 months, however, only 31.6% of respondents had visited dentists before. There was a statistically significant relationship between tooth brushing technique and type of school attended by the respondents (P < 0.05. Conclusion: Majority of the respondents have good oral health knowledge but poor dental health practice.

    Aggressive periodontitis is a rare, severe and rapidly progressing periodontal disease. Early diagnosis is of utmost importance for establishing treatment in order to stop periodontal destruction and prevent tooth loss. The aim of this study is to describe the occurrence of aggressive periodontitis in patients at a Dental School in Brazil by means of a cross-sectional study. First, records from patients aged 15-36 years were consecutively scrutinized. Patients should not have systemic diseases. The search went up to 383 valid records. By means of periapical radiographs, the distance between the cement-enamel junction and the bone crest was measured. Records in which there was severe bone loss or periodontal destruction incompatible with the age of the patient were selected. Patients with bone loss > or = 3mm were called to answer a questionnaire and undergo periodontal examination, in order to confirm or dismiss the diagnosis of aggressive periodontitis. From a total 383 records, 55.1% (211) were female and 44.9% (172) were male. In 3.9% (15) of the records, presumed diagnosis was aggressive periodontitis, and 12 out of those 15 eligible patients (80%) came in for clinical examination and confirmation or dismissal of the diagnosis. Aggressive periodontitis was diagnosed in 7 patients, corresponding to 1.8% of the total. Of these, 4 (1% of the total) presented generalized aggressive periodontitis and 3 (0.8% of the total) presented localized aggressive periodontitis. In 5 patients (1.3%) chronic periodontitis was diagnosed. It may be concluded, within the limits of the study, that aggressive periodontitis at this Dental School is compatible with world prevalence values, suggesting the need for periodontal diagnosis as from adolescence, considering the possible damage caused by this disease.

    This project, utilizing a seldom-used approach to dental education, was designed to define the desired characteristics of a graduating dental student; convert those characteristics to educational outcomes; and use those outcomes to map a dental school's learning and assessment programs, based on outcomes rather than courses and disciplines. A detailed rubric of the outcomes expected of a graduating dental student from this school was developed, building on Commission on Dental Accreditation (CODA) standards and the school's competencies. The presence of each characteristic in the rubric was mapped within and across courses and disciplines. To assess implementation of the rubric, members of two faculty committees and all fourth-year students were asked to use it to rate 1) the importance of each characteristic, 2) the extent to which the school teaches and assesses each, and 3) the extent to which each counts toward overall assessment of competence. All thirty-three faculty members (100 percent) on the committees participated, as did forty-six of the fifty-five students (84 percent). The groups gave high scores to the importance of each characteristic, especially for knowledge and technical competence (then separate categories but merged in the final rubric) and for self-assessment, as well as the extent to which they are being taught and assessed. Respondents most commonly named critical thinking as the area that should be emphasized more. Mapping the curriculum and creating its related database allow the faculty and administration to more systematically coordinate learning and assessment than was possible with a course-based approach.

    Recently, dental stem and progenitor cells have been harvested from periodontal tissues such as dental pulp, periodontal ligament, follicle, and papilla. These cells have received extensive attention in the field of tissue engineering and regenerative medicine due to their accessibility and multilineage differentiation capacity. These dental stem and progenitor cells are known to be derived from ectomesenchymal origin formed during tooth development. A great deal of research has been accomplished for directing osteoblastic/cementoblastic differentiation and neural differentiation from dental stem cells. To differentiate dental stem cells for use in tissue engineering and regenerative medicine, there needs to be efficient in vitro differentiation toward the osteoblastic/cementoblastic and neural lineage with well-defined and proficient protocols. This would reduce the likelihood of spontaneous differentiation into divergent lineages and increase the available cell source. This review focuses on the multilineage differentiation capacity, especially into osteoblastic/cementoblastic lineage and neural lineages, of dental stem cells such as dental pulp stem cells (DPSC), dental follicle stem cells (DFSC), periodontal ligament stem cells (PDLSC), and dental papilla stem cells (DPPSC). It also covers various experimental strategies that could be used to direct lineage-specific differentiation, and their potential applications in tissue engineering and regenerative medicine.

State and private schools in the state of Paraiba, Brazil. 1665 obese and 1665 normal-weight adolescents. These were chosen by means of an anthropometric study using height/age and weight/height indices, adopting as baseline the National Center for Health Statistics indices. The diagnostic criteria for caries were those of the World Health Organization (1997). The average DMFT for obese adolescents from state schools was 4.27 and for those of normal weight it was 4.25 (p = 0.7802). In private schools, the corresponding figures were 1.90 and 1.91, respectively (p = 0.1151). In state schools, the caries prevalence amongst the obese group was 50.9% and amongst those of normal weight, 52.4% (p = 0.5393). In private schools, it was 9.0% amongst the obese group and 9.6% amongst those of normal weight (p 0.6790). There was no statistically significant association between dental caries and obesity. Caries levels were higher amongst adolescents attending state schools.

    Full Text Available Introduction. Radiovisiography (RVG as the latest imaging technique in dentistry with the minimal radiation exposure of the patient and numerous possibilities to process the images has many advantages over classic radiography. Case report. We presented an interesting clinical endodontic case of primary posted diagnosis of traumatic periodontitis of upper right canine upon orthodontics treatment. As the patient previously had been exposed to alleged high dose of radiation the patient agreed to minimal exposition using digital RVG. The options of the tool bar of RVG Trophy device enabled the solving of ethiologic factor of presented periodontitis. The enigma of the symptoms on the ’overfilled’ root canal was solved zooming and 3-D analysis avoiding periapical surgery owing to the patience of the patient and the dentist in a couple of days. Conclusion. By applying RVG technique the time for diagnostic procedure is much shorter in comparison with traditional dental radiography enabling archiving and follow-up the presented case in the course of time.

    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

    Dental caries affects quality of life and has a negative impact on daily performance. The study was conducted to assess the impact of oral health and its associated factors in schoolchildren in the age group 12-15 years in Indore, Madhya Pradesh. A cross-sectional survey was conducted in schoolchildren in the age group 12-15 years. Sociodemographic and oral health related behaviors of schoolchildren were collected using a self-administered questionnaire. Child oral impact on daily performance (OIDP) questionnaire was used to assess the oral impacts. Oral examination was performed to check the presence of caries using decayed, missing and filled teeth (DMFT) index. A total of 690 schoolchildren participated in the survey. The mean age of the children was 13.58 years. The overall prevalence of dental caries was found to be 47.2%. The prevalence of one or more impact in the study population was 36.5%. The most prevalent impact was difficulty in eating and cleaning of teeth and the least prevalent impact were emotion and studying. Results of logistic regression analysis showed that the type of school that a child goes to, socioeconomic status, material used, dental visit, and dental caries were significantly associated with the Child-OIDP affected score. Oral health had a significant effect on the quality of life of schoolchildren. The prevalence of dental caries was found to be high. Effective policies need to be drafted for oral health promotion in this age group.

    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.

    Full Text Available Introduction: Globally, non-communicable diseases are increasingly recognized as a major cause of morbidity and mortality. Among them, overweight and obesity are imperative. The problem of overweight and obesity is not confined to adults but also to children and adolescents. The present changing dietary pattern among children is contributing to childhood overweight and on other hand stands as a risk factor in the development of dental caries, hence the study aimed to investigate the relation between overweight and dental caries among school children. Materials and Methods: A cross-sectional study was conducted among 5-6-year and 12-year-old school children to evaluate the relation between body mass index (BMI and dental caries. Using stratified random sampling technique 1017 school children were selected. Subjects who have brought consent from their parents were included and subjects who were absent on the day of examination were excluded. A pre-structured questionnaire was prepared to collect data regarding demographic details, oral hygiene practices, dentition status and treatment needs, (BMI, 24-hour diet history, physical activity, and television watching. The data collected were subjected to statistical analysis (SPSS V 16.0 using Chi-square and multivariate logistic regression tests. Results: "Risk of overweight" 20% and an "overweight" of 40% were observed. With BMI, parental overweight (P = 0.001, socioeconomic status (SES (P = 0.001, physical activity (P = 0.001 and television watching (P = 0.001 were found to be statistically related. Body mass index and dental caries were not statistically related. Conclusion: These complex and multifactorial relations like overweight and dental caries may involve many unknown factors which warrant exploration on larger population.

    Fluoride intake at optimal level decreases the incidence of dental caries. However, excessive intake, especially during developmental stages can cause adverse effects such as dental and skeletal fluorosis. To assess the prevalence and severity of dental fluorosis in primary school children born and raised in three villages of Mysore District. The three selected villages have different water fluoride concentrations. Three villages namely, Nerale (water fluoride 2.0 ppm), Belavadi (1.2 ppm) and Naganahally (0.4 ppm) were selected for the study. Then, a total of 405 children, 10-12-year-old (204 [50.4%] males and 201 [49.60%] females) were selected from three schools of the villages. Dean's fluorosis index recommended by World Health Organization was used to evaluate fluorosis among the study population. The overall prevalence of dental fluorosis was found to be 41.73%. An increase in the community fluorosis index (CFI) was higher among those living in high water fluoride area. A significantly positive correlation was found between CFI and water fluoride concentration in drinking water.

    Objectives: Several medical and dental schools have described their experience in the transition from conventional to digital microscopy in the teaching of general pathology and histology disciplines; however, this transitional process has scarcely been reported in the teaching of oral pathology. Therefore, the objective of the current study is to report the transition from conventional glass slide to virtual microscopy in oral pathology teaching, a unique experience in Latin America. Study Design: An Aperio ScanScope® scanner was used to digitalize histological slides used in practical lectures of oral pathology. The challenges and benefits observed by the group of Professors from the Piracicaba Dental School (Brazil) are described and a questionnaire to evaluate the students’ compliance to this new methodology was applied. Results: An improvement in the classes was described by the Professors who mainly dealt with questions related to pathological changes instead of technical problems; also, a higher interaction with the students was described. The simplicity of the software used and the high quality of the virtual slides, requiring a smaller time to identify microscopic structures, were considered important for a better teaching process. Conclusions: Virtual microscopy used to teach oral pathology represents a useful educational methodology, with an excellent compliance of the dental students. Key words:Digital microscopy, virtual microscopy, dental education, virtual slides, oral pathology. PMID:25129250

    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.

    This study aimed to determine the prevalence of dental fluorosis and its relationship to socioeconomic status, knowledge, and awareness among 12-year-old school children in Quetta, Pakistan. A cross sectional study was conducted among 349 school children aged 12 years in Quetta, Pakistan. By interviewing children and questionnaire for parents, socioeconomic status, knowledge, and awareness of fluorosis were collected. Dental fluorosis was examined using Dean's Index and Community Fluorosis Index. Prevalence of dental fluorosis was high (63.6%) among children with a majority of moderate and mild degree at 32.1% and 27.5%, respectively. The community fluorosis index was 1.6. While most children and parents had low-to-moderate levels of fluorosis knowledge, the majority of them worried about dental fluorosis. Most parents (84.8%) were uncertain about the condition of fluorosis in their children, and 87.4% did not know about fluorosis before. Dental fluorosis was found significantly associated with gender, family income, and parents' awareness (p ≤ 0.05). Multivariate analysis indicated that gender, and parent's awareness significantly predicted children's dental fluorosis. Knowledge and basic information regarding dental fluorosis is lacking in the community. Efforts in dissemination and communication about dental fluorosis should be increased in order to raise awareness and prevent the dental fluorosis in Pakistan.

    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 assess the prevalence and severity of dental fluorosis and dental caries among 12 and 15 years old children in relation to fluoride concentration in drinking water . It was a cross-sectional study, done in Nalgonda district of Andhra Pradesh, India (endemic fluoride belt) . 5 of the 59 mandals in the district of Nalgonda were selected by simple random sampling. Then, 3 schools from each of these selected mandals were chosen at random. All the eligible 6 th and 9 th standard children were considered for final analysis. The demographic and other relevant information was collected by 3 trained and calibrated dentists, using a structured questionnaire. Dental caries were recorded using dentition status and treatment needs and fluorosis were recorded by Dean's fluorosis index. The statistical analysis was done using SPSS version 16. The prevalence of dental caries among children was 56.3% with the highest in below optimal fluoride area (71.3%) and lowest in optimal fluoride area (24.3%). The prevalence of dental fluorosis was 71.5%. The prevalence was 39.7% in below optimal fluoride area and 100% in high and very fluoride areas. The prevalence and severity of fluorosis increased with increasing fluoride concentration. The caries experience was more among boys than girls. There was a negative correlation between dental caries and fluoride concentration for the entire study population. However, in high fluoride areas, there was a positive correlation between fluoride concentration and dental caries. Water defluoridation on an urgent basis is a priority here than water fluoridation, because the prevalence and severity of dental flurorosis is very high.

    The prevalence of dental caries (tooth decay) among preschool children is increasing, driven partially by an earlier age of onset of carious lesions. The American Academy of Pediatrics recommends application of 5% sodium fluoride varnish at intervals increasing with caries risk status, as soon as teeth are present. However, the varnishes are marketed for treatment of tooth sensitivity and are regulated as medical devices rather than approved by the US Food and Drug Administration for preventi...

    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.

    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.

    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.

    The aim of this study was to evaluate the knowledge and behavior of dentists regarding toothbrush disinfection. This study included 147 dentists (88 women and 59 men) who were actively employed at a dental school in Ankara, Turkey. Participants were asked to fill out a standard questionnaire, which contained questions regarding their demographics, brushing habits, toothbrush storage and disinfection habits, toothpaste use, knowledge about toothbrush disinfection, and whether they advised their patients about toothbrush storage. Descriptive statistics were calculated, and statistical analyses were performed with t-tests, chi-squared tests, and Fisher exact tests, where appropriate. Among the 147 surveyed dentists, 62.6% and 85.7% reported that they did not have any knowledge about toothbrush disinfection and did not disinfect their toothbrushes, respectively. However, approximately two thirds of surveyed dentists thought that toothbrush disinfection should be performed by everyone, including healthy individuals. Significant associations were found between knowledge about toothbrush disinfection and the professional title of dentists, how they stored their toothbrushes, and whether their toothbrushes were in contact with each other during storage (p toothbrushes.

    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.

    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.

    It has been observed that the prevalence of dental caries among children has declined in the last decade in Germany. However, despite of these improvements there is still a proportion of children suffering from dental decay. The aims of this study were to evaluate if a social gradient in the prevalence of dental caries exists and, based on those findings, to develop a strategy to target those children with heightened risk to develop dental caries in order to assist oral health care professionals to refocus the current uniform school-based dental health programme to a caries preventive strategy based on a directed population approach. A representative, random sample of 12-year olds in Freiburg (Germany) was examined and dental caries was recorded using WHO criteria. Educational attainment of the child's parents was used as an indicator of socio-economic status and classified by use of the CASMIN Educational Classification. A total of 322 children participated. An examination of dental caries score revealed that its distribution was positively skewed. For this reason this study provides summary analyses based on medians and a non-parametric rank-sum test. The Kruskal-Wallis H-test showed a significant difference between median scores across the different educational levels (p-value = 0.015) which was due to lower dental caries levels in children with non-deprived social background. In order to reduce current social inequalities in child oral health the current uniform school-based dental health programme at secondary school level should be developed to a targeted school-based screening and prevention programme.

    This study presents data on the prevalence and severity of dental fluorosis in 11-15-years-old school children of Kanyakumari district, TamilNadu, India, and also the relationships between prevalence of dental fluorosis and selected risk factors. A total of 1800 children, from all the nine blocks of Kanyakumari district, studying in classes 6-10 were examined using type III examination. The assessment form designed specifically for this study was used while examining each student. Dental fluorosis was present in 15.8% (285 children) of the study population and the community fluorosis index was calculated to be 0.27. The prevalence of dental fluorosis varied from as low as 1.4% in some blocks to as high as 29.4% in some others. There was a significant difference in the level of dental fluorosis between rural and urban residents ( P prevalence of dental fluorosis was higher in children who consumed pipe water as compared to children who consumed ground water. 65% of the children with dental fluorosis had no caries, indicating the positive effects of fluoride. The prevalence of dental fluorosis can be attributed to the level of fluoride in the drinking water as it exhibited a step-wise increase when the water fluoride levels increased from 1.5-1.7 ppm. Measures for defluoridation of drinking water before distribution has to be taken in the high prevalence blocks to lower the burden of dental fluorosis in this community.

    Empathy has been identified as a crucial foundation in building an effective dentist-patient relationship. The aim of this study was to assess patients' perceptions of dental students' empathic care in the primary oral health care clinic at International Medical University in Kuala Lumpur, Malaysia in May-October 2014. The study also assessed the validity and reliability of the Consultation and Relational Empathy (CARE) Measure in this setting; the association between number of encounters and students' CARE Measure scores; and the association between students' empathy (measured by the Toronto Empathy Questionnaire) and CARE Measure scores. Participants were 283 patients (aged ≥18 years) who were asked to self-complete the ten-item CARE Measure immediately after their clinical encounter with students who provided care under supervision of the teaching staff. The results showed that the CARE Measure demonstrated good internal consistency (Cronbach's α=0.95). A single factor solution emerged, accounting for 69% of the variance. The mean CARE Measure score in the consultations was 43.55±6.14, and 26% of the students achieved the maximum possible score of 50. The mean number of encounters with each student was 2.33±2.78. An increase of one episode was associated with an insignificant average CARE score decrease of 0.05 (-0.28, 0.38), whereas students' empathy was associated with a small increase in average CARE Measure score of 0.63 (0.08, 1.18). These results provide evidence of the measure's ability to support feedback to dental students on their empathy when interacting with patients.

    Full Text Available Abstract Background Pit and fissure sealants (sealants are widely used as a non-operative preventive method in public dental health in Finland. Most children under 19 years of age attend the community-organized dental health services free of charge. The aims of this study were to find out to what extent sealants were applied, what the attitudes of dental professionals towards sealant application were, and whether any existing sealant policies could be detected among the health centres or among the respondents in general. The study evaluated changes that had taken place in the policies used during a ten year period (1991–2001. Methods A questionnaire was mailed to each chief dental officer (CDO of the 265 public dental health centres in Finland, and to a group of general dentists (GDP applying sealants in these health centres, giving a total of 434 questionnaires with 22 questions. The response rate was 80% (N = 342. Results A majority of the respondents reported to application of sealants on a systematic basis for children with increased caries risk. The criteria for applying sealants and the actual strategies seemed to vary locally between the dentists within the health centres and between the health centres nationwide. The majority of respondents believed sealants had short- and long-term effects. The overall use of sealants decreased towards the end of the ten year period. The health centres (N = 28 choosing criteria to seal over detected or suspected enamel caries lesion had a DMFT value of 1.0 (SD ± 0.49 at age 12 (year 2000 compared to a value of 1.2 (SD ± 0.47 for those health centres (N = 177 applying sealants by alternative criteria (t-test, p Conclusion There seems to be a need for defined guidelines for sealant application criteria and policy both locally and nationwide. Occlusal caries management may be improved by shifting the sealant policy from the traditional approach of prevention to interception, i.e. applying the sealants

    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.

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

    2009-07-01

    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

    Many health professions students who treat Spanish-speaking patients in the United States have little concept of their culture and health related traditions. The lack of understanding of these concepts may constitute major barriers to healthcare for these patients. International service-learning experiences allow students to work directly in communities from which patients immigrate and, as a result, students gain a better understanding of these barriers. This article describes the implementation of an international, multidisciplinary, service-learning program in a dental school in the United States. The Indiana University International Service-Learning program in Hidalgo, Mexico began in 1999 as an alternative spring break travel and clinical experience for medical students, focusing on the treatment of acute health problems. Travel-related preparatory sessions were offered, and no learning or service objectives had been developed. The program has evolved to include a multidisciplinary team of dental, medical, nursing, public health and social work students and faculty. The experience is now integrated into a curriculum based on the service-learning model that allows students to use their clinical skills in real-life situations and provides structured time for reflection. The program aims to enhance teaching and foster civic responsibility in explicit partnership with the community. Preparatory sessions have evolved into a multidisciplinary graduate level course with defined learning and service objectives. PROGRAM EVALUATION METHODS: In order to assess the program's operation as perceived by students and faculty and to evaluate student's perceptions of learning outcomes, evaluation tools were developed. These tools included student and faculty evaluation questionnaires, experiential learning journals, and a strengths, weaknesses, opportunities and threats analysis. Evaluation data show that after program participation, students perceived an increase in their

    Several medical and dental schools have described their experience in the transition from conventional to digital microscopy in the teaching of general pathology and histology disciplines; however, this transitional process has scarcely been reported in the teaching of oral pathology. Therefore, the objective of the current study is to report the transition from conventional glass slide to virtual microscopy in oral pathology teaching, a unique experience in Latin America. An Aperio ScanScope® scanner was used to digitalize histological slides used in practical lectures of oral pathology. The challenges and benefits observed by the group of Professors from the Piracicaba Dental School (Brazil) are described and a questionnaire to evaluate the students' compliance to this new methodology was applied. An improvement in the classes was described by the Professors who mainly dealt with questions related to pathological changes instead of technical problems; also, a higher interaction with the students was described. The simplicity of the software used and the high quality of the virtual slides, requiring a smaller time to identify microscopic structures, were considered important for a better teaching process. Virtual microscopy used to teach oral pathology represents a useful educational methodology, with an excellent compliance of the dental students.

    Full Text Available Introduction: Periodic evaluation of educational programs provides insight into the course and teaching effectiveness. Effective evaluation provides valuable information, which contributes to both student’s and course success. The purpose of this study was to evaluate the success of pediatric dentistry department at Mashhad dental school in clinical education from students’ perspectives.Materials & Methods: This cross-sectional study was conducted on 116 fifth and sixth grade undergraduate dental students in pediatric dentistry at Mashhad dental school. A questionnaire including 21 multiple choice questions about 7 parts of clinical skills in pediatric dentistry was given to each student. Data were analyzed by Mann-Whitney in SPSS software. Results: According to the study results, among 7 different clinical skills in pediatric dentistry including: examination, behavior management, prevention, injection, restoration, pulp treatment and space management, the highest success rate of pediatric dentistry department was in prevention and injection and the lowest success rate in space management and behavior control. Furthermore, from the students’ perspective, male students compared to female students mentioned a higher rate of success in choosing the type of restoration material for pediatric dentistry department (P=0. 041. Conclusion: This study showed that the students’ self-reported clinical skills in different parts of pediatric dentistry has been adequate. Students reported a lack of confidence in “behavior management” and “space management” which warrants greater emphasis in the undergraduate curriculum.

    The purpose of the present study was to review indexed literature and provide an update on the effectiveness of high-frequency radio waves (HRW) application in modern general dentistry procedures. Indexed databases were searched to identify articles that assessed the efficacy of radio waves in dental procedures. Radiosurgery is a refined form of electrosurgery that uses waves of electrons at a radiofrequency ranging between 2 and 4 MHz. Radio waves have also been reported to cause much less thermal damage to peripheral tissues compared with electrosurgery or carbon dioxide laser-assisted surgery. Formation of reparative dentin in direct pulp capping procedures is also significantly higher when HRW are used to achieve hemostasis in teeth with minimally exposed dental pulps compared with traditional techniques for achieving hemostasis. A few case reports have reported that radiosurgery is useful for procedures such as gingivectomy and gingivoplasty, stage-two surgery for implant exposure, operculectomy, oral biopsy, and frenectomy. Radiosurgery is a relatively modern therapeutic methodology for the treatment of trigeminal neuralgia; however, its long-term efficacy is unclear. Radio waves can also be used for periodontal procedures, such as gingivectomies, coronal flap advancement, harvesting palatal grafts for periodontal soft tissue grafting, and crown lengthening. Although there are a limited number of studies in indexed literature regarding the efficacy of radio waves in modern dentistry, the available evidence shows that use of radio waves is a modernization in clinical dentistry that might be a contemporary substitute for traditional clinical dental procedures.

In this work the characterization of a recently developed sol-gel-derived bioactive glass ceramic containing silver ions (Ag-BG) is presented. The microstructural characteristics, ion release profile, zeta potential value and changes in weight loss and pH value as a function of the immersion time of Ag-BG in Tris buffer are evaluated. Ag-BG is also incorporated into natural extracellular matrix (ECM) hydrogel to further enhance its regenerative properties. Then, the micro and macro architectures of these new composites (ECM/Ag-BG) are characterized. In addition, the antibacterial properties of these new composites are tested against Escherichia coli and Enterococcus faecalis, a bacterium commonly implicated in the pathogenesis of dental pulp infections. Cell-material interaction is also monitored in a primary culture of dental pulp cells. Our study highlights the benefits of the successful incorporation of Ag in the bioactive glass, resulting in a stable antibacterial material with long-lasting bactericidal activity. Furthermore, this work presents for the first time the fabrication of new Ag-doped composite materials, with inductive pulp-cell proliferation and antibacterial properties (ECM/Ag-BG). This advanced composite made of Ag-BG incorporated into natural ECM possesses improved properties that may facilitate potential applications in tooth regeneration approaches.

    Objective: Dental caries is frequently observed in children, particularly among those residing in developing countries. The most adapted strategies against this pathology remains prevention based on information, education, and communication (IEC), as well as on early diagnosis and treatment. We carried out a study that aimed to analyze the development of dental caries in a cohort of school children followed during their primary education. The objective was to assess the evolution of the dental status of a cohort of students during their elementary curriculum. Materials and Methods: A cohort of school children was followed during 6 years from the first grade to the sixth grade. Monitoring of these school children focused every year on IEC based on learning methods of brushing messages, dietary advice, systematic visits, fluoride use, and primary dental care. During the school year, the students were periodically subjected to education and communication briefings (IEC). Primary care consisted of extracting and descaling rhizalyzed teeth in the same period. The data from this review were collected using the World Health Organization questionnaire, and statistical analysis was performed with the software Epi-info version 6.04 d. Results: The mean age of the 171 school children was 6 years in the first grade and 11 years in the sixth grade. In the first grade, the decayed permanent teeth prevalence was 31.6% and the In permanent teeth: Decayed, missing or filled teeth (DMF/T) was 0.47. The decayed primary teeth prevalence was 75% and the in primary teeth: decayed or filled teeth (df/t) 2.23. In the sixth year, the prevalence of decayed permanent teeth was 51% and DMF/T 0.36 whereas the decayed primary teeth prevalence was 12% and the df/t was 0.19. The prevalence of decayed permanent teeth increased from 31.6 to 51% whereas the mean DMF/T was not statistically different between school children of the first and sixth grade class. Conclusion: The promotion of oral health

    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.

    The aim of this research is related with the diagnosis of caries by use of a laser. We study the fundamental characterization of the diagnosis method using both fluorescence and Raman scattering spectroscopy. We try to evaluate the possibility of the caries diagnosis using Raman spectroscopy and its clinical application. We focus on the PO34- ion that flows out with the dissolution of hydroxyapatite (HAp), and the fluorescence that increases in connection with caries. The Raman line of P-O vibration is overlapped on the continuous, background spectrum by fluorescence. Consequently, we try to find out the correlation between a healthy part and a carious part by analyzing both fluorescence and Raman spectra. It was found that Raman intensity of HAp at carious lesion was weaker than those of healthy parts and the florescence intensity at the same portions was stronger. We have obtained the feasibility to estimate the degree of caries and health condition by deriving the ratio between Raman and florescence intensity. And the trial measurements in vivo were carried out to verify the availability of the method by using a fiber probe type multi channel Raman spectrometer. The process of remineralization is under researching for the development of preventive medicine.

    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.

    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.

    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 p<0.05. From 1999-2004 to 2011-2014, among low- and higher-income children, sealant use prevalence increased by 16.2 and 8.8 percentage points to 38.7% and 47.8%, respectively. Among low-income children aged 7-11 years, the mean DFFM was almost three times higher among children without sealants (0.82) than among children with sealants. Approximately 6.5 million low-income children could potentially benefit from the delivery of sealants through SBSP. The prevalence of dental 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.

    Although the adhesion phenomenon is crucial in achieving and maintaining a composite building on dental structure, this phenomenon is not completely understood. On the other hand, adhesion is dependent on the interface quality (the interface between enamel and adhesive). In this study, the authors approached the subject of the influence of adhesive clinical application on the composite-enamel interface, which was less investigated by the scientists. On intact extracted human teeth were prepared enamel areas, and then filled with light-curing composite. The teeth were sectioned and prepared for microscopic investigation, at 10×, 100× and 200× magnifications.

    The identification of specific patterns of dental anomalies would allow testing the hypothesis that certain genetic and environmental factors contribute to distinct dental anomaly subphenotypes. A sexual dimorphism in tooth agenesis and its association with other dental anomalies has been suggested. The aim of this study was to investigate a large group of children to define dental anomaly subphenotypes that may aid future genetic studies. Orthopantamograms of 1198 subjects were examined and 1167 were used in this study. The frequency of tooth agenesis in the studied population was 4.8%. Male:female ratios varied from 2:1 in the agenesis of upper lateral incisors to 0.5:1 in premolar agenesis. The risk of infra-occlusion of primary molars and double formation of primary incisors was increased in individuals with tooth agenesis.

    The field of optical fiber sensing is highly diverse and this diversity is perceived as a great advantage over more conventional sensors in that an optical sensor can be tailored to measure any of a myriad of physical parameters. In this paper we present a niche application for optical fiber sensors in the domain of biophotonics, namely the monitoring of stress build-up during the curing process of dental resin cements. We discuss the origin of this stress build-up and the problems it can cause when treating patients. Optical fiber sensors aim at excelling in two kind of applications: firstly to perform quality control on batch produced dental cements and measure their total material shrinkage, secondly to monitor the hardening of the cement during in-vivo measurements resulting in the dynamic measurement of the shrinkage and to control the stress in a facing based restoration. We therefore investigated two types of optical fiber sensors as alternatives to conventional measurement techniques; namely polarimetric optical fiber sensors and fiber Bragg gratings written in polarization maintaining fibers. After discussing the results obtained with both optical fiber sensors, we will conclude with a critical assessment of the suitability of the two proposed sensing configurations for multi-parameter stress monitoring.

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.

    The purpose of this study was to repeat a 1997 survey of current pulp therapy practice. The directors of dental school predoctoral pediatric dentistry programs (N=56) and board certified pediatric dentists (N=1200) were surveyed in 2005. More dental schools (83%) taught indirect pulp therapy (IPT) compared to 1997. Significantly more used glass ionomer for IPT with most dental schools and diplomates not re-entering a tooth after IPT. Over 30% of schools and diplomates do direct pulp cops using glass ionomer. For pulpotomy, diluted formocresol usage decreased in dental schools (54%) while ferric sulfate significantly increased (24%) and full strength remained at 22%. Shorter placement of pulpotomy medication was noted and ZOE alone the preferred base. Pulpectomy was advocated by 85% of 2005 schools and diplomates with ZOE filler use decreasing while iodoform/calcium hydroxide filler use increasing. More pediatric dentists are using glass ionomer for IPT and direct pulp capping, and there was a trend away from the use of 1:5 diluted formocresol with more using ferric sulfate for pulpotomy. For pulpectomy, most use ZOE but iodoform pastes and calcium hydroxide have increased in usage since 1997 Disagreements continue concerning when to use certain pulp therapies and some directors and diplomates did not follow the AAPD guidelines.

    Objectives To assess the prevalence and incidence of dental caries in school-aged African-American children who received semi-annual fluoride varnish applications. Methods A cohort of six-year-old high caries-risk African-American children (n=98) was recruited in Uniontown, Alabama and followed for six years. Oral examinations were done annually by three trained/calibrated dentists. Tooth surfaces with cavitated caries, missing due to caries and with filled surfaces were recorded, using WHO criteria. Also, as part of the study, children received periodic oral health instruction, fluoride varnish applications and referral to dentists starting at baseline. Results The person-level prevalence of dmfs/DMFS was: 61.2 percent at mean age 5.9 (n=98, mean dmfs/DMFS=11.6); 63.8 percent at age 6.7 (n=80, mean dmfs/DMFS=13.2); 70.6 percent at age 7.8 (n=68, mean dmfs/DMFS=14.2); 65.7 percent at age 8.8 (n=68, mean dmfs/DMFS=11.8); 55.6 percent at age 9.7 (n=63, mean dmfs/DMFS=8.8); 40.3 percent at age 10.7 (n=62, mean dmfs/DMFS=3.4); and 37.1 percent at age 11.7 (n=62, mean dmfs/DMFS=2.3). The six-year person-level incidence of dmfs/DMFS was 32.3 percent (mean dmfs/DMFS=1.6) from age 5.9 to age 11.7 (n=62). Conclusion In spite of the oral health education and fluoride varnish applications, there was substantial new dental caries in this high-risk sample. Additional studies evaluating risk factors for caries development are ongoing. PMID:27306247

    The present study was conducted to assess the relationship between drinking water fluoride (F) levels, dental fluorosis and dental caries among 9-12 years old school children of Nelakondapally Mandal, Khammam district, Andhra Pradesh. A cross-sectional analytical study was conducted on 1500 school children aged 9-12 years, selected by stratified random sampling from different areas with different levels of naturally occurring F in drinking water. The children were assessed for dental fluorosis according to WHO basic survey guidelines. The overall oral health status of the child was assessed by decayed missing filled teeth (DMFT)/dmft index. Statistical analysis was done using mean, standard deviation, standard error, Z-test, ANOVA test, and Chi-square test. The results of the present study revealed that the prevalence of fluorosis was 74.9%. Number of children having dental fluorosis was highest in children who consume water from bore wells. Caries prevalence in the study population was about 56.5%. Caries prevalence and mean DMFT/dmft scores were least in children with optimal F areas and highest in children with below optimal F areas. There was moderate prevalence of fluorosis in Nelakondapally Mandal of Khammam district, and caries prevalence is high in areas below optimal F areas.

    Full Text Available Dentistry nowadays can count on a wide range of resources to treat patients. With the development of adhesive materials and several newly introduced restorative techniques, the dental structure can be subjected to different sorts of surface treatment. The use of aluminum oxide flow at high speed to remove dental structure was described by Black in 1945, however, the literature regarding the use of aluminum oxide jet is still scarce, as far as the alterations occurring in the dental structure are concerned. At the present, with the development of new abrasive air equipment, microabrasion has been added to several adhesive restorative techniques, in the preparation of the dental surface and of inner surfaces of indirect restorations, which will receive the application of adhesive materials. The aim of this study was to assess the alterations produced by abrasive air applied on the dental enamel by means of electronic microscopy, taking into consideration micromorphological surface alterations. The importance of this study is based on the fact that alternative surface treatments both chemical and mechanical could be introduced in surface priming, including dental enamel priming.

    Background 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. Objectives This study aimed to assess the prevalence of traumatic dental injuries to anterior teeth among 12-year-old school children in Kashmir, India. Patients and Methods 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. Results 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 sports were the most common causes of trauma in the present study. The highest potential risk factor for the occurrence of trauma was over jet. Academic performance was found to be significantly associated to TDI to anterior teeth, when analyzed in a multiple regression model. Conclusions 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

    Dental caries inequalities still severely burden individuals' and society's health, even in countries where fluoride toothpastes are widely used and the incidence of dental caries has been decreasing. School-based fluoride mouth-rinse (S-FMR) programs, a population strategy for dental caries prevention, might decrease dental caries inequalities. This study investigated the association between S-FMR and decreasing dental caries prevalence and caries-related inequalities in 12-year-olds by Japanese prefecture. We conducted an ecological study using multi-year prefecture-level aggregated data of children born between 1994 and 2000 in all 47 Japanese prefectures. Using two-level linear regression analyses (birth year nested within prefecture), the association between S-FMR utilization in each prefecture and 12-year-olds' decayed, missing, or filled permanent teeth (DMFT), which indicates dental caries experience in their permanent teeth, were examined. Variables that could explain DMFT inequalities between prefectures, such as dental caries experience at age 3 years, dentist density, and prefectural socioeconomic circumstances, were also considered. High S-FMR utilization was significantly associated with low DMFT at age 12 (coefficient -0.011; 95% confidence interval, -0.018 to -0.005). S-FMR utilization explained 25.2% of the DMFT variance between prefectures after considering other variables. Interaction between S-FMR and dental caries experience at age 3 years showed that S-FMR was significantly more effective in prefectures where the 3-year-olds had high levels of dental caries experience. S-FMR, administered to children of all socioeconomic statuses, was associated with lower DMFT. Utilization of S-FMR reduced dental caries inequalities via proportionate universalism.

    Full Text Available Abstract Background There is limited evidence of the influence of psychosocial factors and health beliefs on public dental patient's patterns of service use in Australia. The research aims were to examine associations between dental attitudes and beliefs of public dental service users and dental visiting intention and behaviour using the Theory of Planned Behaviour. Methods 517 randomly selected adult public dental patients completed a questionnaire assessing dental attitudes and beliefs which was matched with electronic records for past and future dental service use. A questionnaire measured intentions, attitudes, subjective norms and perceptions of behavioural control and self-efficacy in relation to visiting public dentists. A measure of dental attendance at public dental clinics was obtained retrospectively (over 3 1/2 years and prospectively (over a one year period following the return of the questionnaire by accessing electronic patient clinical records. Results Participants had positive attitudes, subjective norms and self-efficacy beliefs towards dental visiting but perceived a lack of control over visiting the dentist. Attitudes, subjective norms, self-efficacy and perceived control were significant predictors of intention (P Conclusion Public dental patients held favourable attitudes and beliefs but perceived a lack of control towards dental visiting. Reducing structural barriers may therefore improve access to public dental services.

    Full Text Available Abstract Background Oral hygiene education is central to every stage of periodontal treatment. Successful management of periodontal disease depends on the patient's capacity for oral self-care. In the present study, the oral self-care and perceptions of patients attending a dental school clinic in Japan were assessed using a short questionnaire referring to existing oral health models. Methods A cross-sectional study design was used. The study population consisted of sixty-five patients (age range 23-77 with chronic periodontitis. The pre-tested 19-item questionnaire comprised 3 domains; 1 oral hygiene, 2 dietary habits and 3 perception of oral condition. The questionnaire was used as a part of the comprehensive assessment. Results Analyses of the assessment data revealed no major problems with the respondents' perceived oral hygiene habits, although their actual plaque control levels were not entirely adequate. Most of the respondents acknowledged the importance of prevention of dental caries and periodontal diseases, but less than one third of them were regular users of the dental care system. Twenty-five percent of the respondents were considered to be reluctant to change their daily routines, and 29% had doubts about the impact of their own actions on oral health. Analyzing the relationships between patient responses and oral hygiene status, factors like 'frequency of tooth brushing', 'approximal cleaning', 'dental check-up' and 'compliance with self-care advice' showed statistically significant associations (P Conclusion The clinical utilization of the present questionnaire facilitates the inclusion of multiple aspects of patient information, before initiation of periodontal treatment. The significant associations that were found between some of the self-care behaviors and oral hygiene levels document the important role of patient-centered oral health assessment in periodontal care.

    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.

    Full Text Available Introduction: The World Health Organization has a long tradition on the methodology and monitorization of oral health epidemiological investigations, even in the field of dental caries. According to the targets to be attained in 2020, at the age of 6 years, 80% of children should be cavity‐free and, at the age of 12, DMFT should be no more than 1.5. Based on WHO targets for 2020, an epidemio‐ logical study was performed on school children affected by dental caries, aged between 7‐12 years, from the rural areas of the Dolj County. Methodology: The study protocol included conventional and meticulous visual clinical examination of students, according to WHO methodology, in the Pedodontic Clinics of Craiova ‐ Faculty of Medical Dentistry. Also calculated was the DMFT index, by analy‐ sis of the DT, MT, FT components, as well as the dmft index, by analysis of the dt, mt, ft components. Results: The mean indices of carious experience in temporary den‐ tition decrease with age, due to the progressive disappear‐ ance of milk teeth. The DMFT index values are given, in particular, by components that indicate the number of teeth affected by caries and not of the blocked ones. Con‐ clusions: The results obtained emphasize the need for den‐ tal health education programs at national and community level, the kindergartens and schools having a great poten‐ tial to influence dental health care habits in children. Also emphasized was the need for regional prevention pro‐ grams, as part of an overall national program, which has to consider the socio‐economic and cultural factors.

    Full Text Available The objective of this study was to assess the association of untreated traumatic dental injuries (TDI with individual-, sociodemographic- and school-related factors among 12-year-old schoolchildren in Midwest Brazil. This cross-sectional study was carried out in 2010 in the city of Goiania, Brazil. A random sample of 2075 schoolchildren was examined and interviewed. Untreated TDI in the permanent incisors was assessed using the methodology of the Brazilian National Oral Health Survey. Rao-Scott test and multinomial logistic regression were used to analyze the associations between independent variables and three categories of TDI, using a hierarchical method. Independent variables were children’s sex, self rated color/race and size of incisal overjet, their mother’s level of schooling, and the schools’ type and geographic location. The prevalence of trauma was 17.3% (CI 95% = 15.2–19.4; enamel fractures were the most common TDI (13.1%. In the adjusted model, a higher chance of having two or more teeth with TDI was found among boys, those whose mothers had lowest level of schooling, and those attending schools located in health districts with lower socioeconomic indicators. It was concluded that the prevalence of TDI was low and that it was associated with individual factors as well as the school environments.

    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.

    most specimens showed an adhesive failure from the adhesive-dentin interface. Energy dispersive X-ray (EDX) mapping confirmed the uniform distribution of nanorods in the adhesive matrix. The colloidal stability studies indicated that synthesized hydroxyapatite nanorods have high colloidal stability in the dental adhesive solution. Indeed, the nanorods are well dispersed and protected from aggregation by their high surface charge confirmed by zeta potential measurement. Hydroxyapatite-based composites have shown promising bioactivity. However, the knowledge about the influence of the nano-sized HAp on the properties of the dental materials, especially dentin bonding adhesives, is yet insufficient. The nanorod containing adhesive system presented here might be considered to have practical applications in dental clinics. 2010 Academy of Dental Materials. Published by Elsevier Ltd.

    Full Text Available Background: Dental caries is one of the main health problems in children. The first permanent molar presents caries more frequently than any other. Objective: To describe the characteristics of dental caries in the first permanent molars in children between 6 and 13 years-old, and to assess oral hygiene and knowledge about the subject in all the patients treated in the stomatology consultation Barrio adentro “El Guapo”, from November 2005 to March 2006. Methods: A descriptive, transversal study showed that most of the patients had dental caries. It was proved that many of them had, at least, on of the first molars affected by dental caries. The quotient first molar affected/ patient was higher than one. Results: There was a decrease in the percentage of healthy permanent first molars. Poor oral hygiene prevailed, with a medium knowledge level on the subject. Most of the parents didn´t know about the first molar dental cavity. Conclusions: It was needed to perform educative tasks aimed at this age group to avoid further damage to this important tooth, central for the development of the stomatognathic system.

    Social media consist of powerful tools that impact not only communication but relationships among people, thus posing an inherent challenge to the traditional standards of who we are as dental educators and what we can expect of each other. 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.

    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.

    The study was undertaken to determine serum/urinary fluoride status and comparison of free T4, free T3 and thyroid stimulating hormone levels of 8 to 15 years old children with and without dental fluorosis living in an endemic and non-endemic fluorosis area. A sample group of 60 male and female school children, with or without dental fluorosis, consuming fluoride-contaminated water in endemic fluoride area of Udaipur district, Rajasthan were selected through a school dental fluorosis survey. The sample of 10 children of same age and socio-economic status residing in non endemic areas who did not have dental fluorosis form controls. Fluoride determination in drinking water, urine and blood was done with Ion 85 Ion Analyzer Radiometer with Hall et al. method. The thyroid gland functional test was done by Immonu Chemiluminiscence Micropartical Assay with Bayer Centaur Autoanalyzer. The significantly altered FT3, FT4 and TSH hormones level in both group1A and 1B school children were noted. The serum and urine fluoride levels were found to be increased in both the groups. A significant relationship of water fluoride to urine and serum fluoride concentration was seen. The serum fluoride concentration also had significant relationship with thyroid hormone (FT3/FT4) and TSH concentrations. The testing of drinking water and body fluids for fluoride content, along with FT3, FT4, and TSH in children with dental fluorosis is desirable for recognizing underlying thyroid derangements and its impact on fluorosis.

    The prevalence of dental caries (tooth decay) among preschool children is increasing, driven partially by an earlier age of onset of carious lesions. The American Academy of Pediatrics recommends application of 5% sodium fluoride varnish at intervals increasing with caries risk status, as soon as teeth are present. However, the varnishes are marketed for treatment of tooth sensitivity and are regulated as medical devices rather than approved by the US Food and Drug Administration for prevention of dental caries (tooth decay). The objective of this research is to examine the safety of use in toddlers by characterizing the absorption and distribution profile of a currently marketed fluoride varnish. We measured urinary fluoride for 5 hours after application of fluoride varnish to teeth in 6 toddlers aged 12 to 15 months. Baseline levels were measured on a separate day. The urine was extracted from disposable diapers, measured by rapid diffusion, and extrapolated to plasma levels. The mean estimated plasma fluoride concentration was 13 μg/L (SD, 9 μg/L) during the baseline visit and 21 μg/L (SD, 8 μg/L) during the 5 hours after treatment. Mean estimated peak plasma fluoride after treatment was 57 μg/L (SD, 22 μg/L), and 20 μg/kg (SD, 4 μg/L) was retained on average. Retained fluoride was 253 times lower than the acute toxic dose of 5 mg/kg. Mean plasma fluoride after placement of varnish was within an SD of control levels. Occasional application of fluoride varnish following American Academy of Pediatrics guidance is safe for toddlers. Copyright © 2014 by the American Academy of Pediatrics.

    As a profession, dentistry is at a point of discernible challenge as well as incredible opportunity in a landscape of evolving changes to health care, higher education, and evidence-based decision making. Respecting the past yet driving forward, a well-mapped future course is critical. Orchestrating this course in a collaborative manner is essential for the visibility, well-being, and potentially the existence of the dental profession. The research performed in dental institutions needs to be contemporary, aligned with biomedical science in general, and united with other disciplines. Dentistry is at risk of attrition in the quality of its research and discovery mission if participation with bioscience colleagues in the collaborative generation of new knowledge is underoptimized. A fundamental opportunity dentistry has is to contribute via its position in academic health centers. Rigorous research as to the impact of interprofessional education and collaborative care on population health outcomes provides significant potential for the dental profession to participate and/or lead such evidence-centered efforts. It is imperative that academic dental institutions are part of interdisciplinary and transdisciplinary organizations that move health care into its new day. Strategizing diversity by bringing together people who have different ways of seeing problems to share perspectives, heuristics, interpretations, technologies, and predictive models across disciplines will lead to impactful progress. Academic dental institutions are a natural part of an emphasis on translational research and acceleration of implementing new scientific discoveries. Dentistry needs to remain an essential and integrated component of higher education in the health professions; doing so necessitates deliberate, respectful, and committed change.

    Full Text Available Objectives: This study presents data on the prevalence and severity of dental fluorosis in 11-15-years-old school children of Kanyakumari district, TamilNadu, India, and also the relationships between prevalence of dental fluorosis and selected risk factors. Materials and Methods: A total of 1800 children, from all the nine blocks of Kanyakumari district, studying in classes 6-10 were examined using type III examination. The assessment form designed specifically for this study was used while examining each student. Results: Dental fluorosis was present in 15.8% (285 children of the study population and the community fluorosis index was calculated to be 0.27. The prevalence of dental fluorosis varied from as low as 1.4% in some blocks to as high as 29.4% in some others. There was a significant difference in the level of dental fluorosis between rural and urban residents ( P < 0.001. The prevalence of dental fluorosis was higher in children who consumed pipe water as compared to children who consumed ground water. 65% of the children with dental fluorosis had no caries, indicating the positive effects of fluoride. Conclusions: The prevalence of dental fluorosis can be attributed to the level of fluoride in the drinking water as it exhibited a step-wise increase when the water fluoride levels increased from 1.5-1.7 ppm. Measures for defluoridation of drinking water before distribution has to be taken in the high prevalence blocks to lower the burden of dental fluorosis in this community.

    Fiber-reinforced composite (FRC) biomedical materials are in contact with living tissues arising biocompatibility questions regarding their chemical composition. The hazards of materials such as Bisphenol A (BPA), phthalate and other monomers and composites present in FRC have been rationalized due to its potential toxicity since its detection in food, blood, and saliva. This study characterized the physicochemical properties and degradation profiles of three different epoxide-based materials intended for restorative dental applications. Characterization was accomplished by several methods including FTIR, Raman, Brunauer-Emmett-Teller (BET) Analysis, X-ray fluorescence spectroscopy, and degradation experiments. Physicochemical characterization revealed that although materials presented similar chemical composition, variations between them were more largely accounted by the different phase distribution than chemical composition.

    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 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.

    In the application of lasers in dentistry, there is a delicate balance between the benefits gained from laser treatment and the heat-related damage arising from laser irradiation. Hence, it is necessary to understand the different processes associated with the irradiation of lasers on dental materials. To obtain insight for the development of a safe and general-purpose laser for dentistry, the present study examines the physical effects associated with the irradiation of a near-infrared free-electron laser (FEL) on the surface of a commonly used silver dental alloy. The irradiation experiments using a 2900-nm FEL confirmed the formation of a pit in the dental alloy. The pit was formed with one macro-pulse of FEL irradiation, therefore, suggesting the possibility of efficient material processing with an FEL. Additionally, there was only a slight increase in the silver alloy temperature (less than 0.9 °C) despite the long duration of FEL irradiation, thus inferring that fixed prostheses in the oral cavity can be processed by FEL without thermal damage to the surrounding tissue. These results indicate that dental hard tissues and dental materials in the oral cavity can be safely and efficiently processed by the irradiation of a laser, which has the high repetition rate of a femtosecond laser pulse with a wavelength around 2900 nm.

    Children have boundless energy, so, they are continuously engaged in some or the other physical activity. It is seen that when child reaches school age, accidents in the school environment in the form of falls, injuries due to contact sports, fights, abuse, etc. are very common and the main cause of traumatic dental injuries. Trauma may vary from minor enamel chipping or avulsion to extensive maxillofacial damage, more serious neck and brain injury, which may cause pain, disfigurement and mental agony, having immediate and long lasting effects. In such cases, a school teacher is in the right position to handle such an emergency and refer the child to the concerned dental surgeon or a pedodontist for further needful care. The main reason for delayed treatment of dental trauma is that people present at the site of injury are unaware of protocol of rapid and appropriate management leading to improper first aid treatment. The purpose of this study was to investigate the awareness of a group of school teachers from different schools about the prevention and emergency management of dental trauma in school children, by means of a questionnaire. Then educating them and reassessing their knowledge after a period of 3 months. Unfortunately, the public is unaware of the risks and does not have enough information about first aid emergency treatment or to avoid traumatic injuries.

    Community-based service-learning is increasingly common in dental education. By definition, service-learning combines educational goals with service to the community, and the community and school are equal partners. The three main goals of service-learning are improving learning, promoting civic engagement, and strengthening communities. There have been calls from many groups to reform dental education to better serve the public, and service-learning is one of the most often recommended methods to help meet this goal. One of the key attributes of service-learning is its potential to promote civic engagement and social responsibility during the student's education. The social responsibility of dentists and aspects of professionalism can be learned by students through participation in well-structured service-learning programs. Community-based service-learning programs can also address societal needs by improving the public's access to oral health care through partnerships among dental schools, oral health providers, and communities. This article describes service-learning programs at several dental schools to illustrate application of this educational strategy in predoctoral dental education. This article also describes challenges that confront schools desiring to implement and sustain service-learning programs, including academic quality, faculty development and training, interprofessionalism, making time in the curriculum, budget, faculty shortages and time, student credit, quality control, and remote sites away from the dental school.

Results of accurate ENT and dentistry physical examination were registered and analyzed using SPSS software and Chi-square and Mantel - Hanzel test. Results: With increasing age, The frequency of abnormal occlusal patterns increases (from 45.5% to 68.2% in males and 25.8% to 48.5% in females, p=0.015. The increasing in degree of palatal tonsilar hypertrophy was related to higher frequency of abnormal occlusal patterns (36.7% in +1 tonsilar hypertrophy, and 70% in +4 tonsilar hypertrophy, p=0.02. Also, history of frequent common colds, and history of previous nasal fractures were related with abnormal patterns [58.9% (p=0.032, and 83.4% (p= 0.043%, respectively].Five other parameters including sinusitis, hypertrophy of nasal turbinates, rhinitis, nasal polyposis and nasal septal deviation were not associated with abnormal occlusal patterns (p>0.1. Conclusion: Some of obstructive upper airwacy diseases are related with abnormal dental occlusal patterns. These parameters can be simply diagnosed, treated or prevented. Key words: dental occlusion, malocclusion, obstructive nasal disorders, nasal turbinates, adenoid, rhinitis, tonsillectomy, open mouth breathing

    Full Text Available Background. Children in low-income developing countries are likely to suffer from undergrowth. Dental caries is another common problem in these countries. Aim. To examine the association between untreated dental caries in primary and permanent teeth with age-adjusted height and weight among 6–12-year-old children in Bangladesh. Design. Social, behavioural, and clinical data were collected from 1699 children in nine different randomly selected primary schools in socially deprived areas of Bangladesh. The associations of age-adjusted weight and height and being underweight with dental caries were examined adjusting for sex, area of residence, socioeconomic position, skipping meals, tooth cleaning, and doctor visits. Results. 26% of the children were underweight and 55% had untreated dental caries. Children with at least one decayed tooth were significantly underweight with odds ratios 1.6 (95% CI 1.1, 2.3 and 1.5 (95% CI 1.1, 2.0 for 6–8-years and 9–12-year-old children, respectively, in the adjusted model. The number of decayed teeth was inversely and significantly associated with the standardized age-adjusted weight. Conclusions. The findings highlight the association between untreated dental caries and being underweight in primary school children in socially deprived areas in low-income developing countries and emphasize the need to integrate oral and general health policies with social policies.

    The United States faces a significant problem with access to oral health care, particularly for children. More than 50 countries have developed an alternative dental provider, a dental therapist, practicing in public, school-based programs, to address children's access to care. This delivery model has been demonstrated to improve access to care and oral health outcomes while providing quality care economically. We summarize elements of a recent major review of the global literature on the use of dental therapists, "A Review of the Global Literature on Dental Therapists: In the Context of the Movement to Add Dental Therapists to the Oral Health Workforce in the United States." We contrast the success of a school-based model of caring for children by dental therapists with that of the US model of dentists providing care for children in private practices.

    To achieve bisphenol A glycerolate dimethacrylate (BisGMA) analogs with reduced viscosity to be used in the formulation of dental adhesives containing biocidal components. A series of low-viscosity BisGMA derivatives (η: 39-12Pas) modified with 30, 60 and, respectively 80mol% carboxylic acid units were synthesized and characterized. Hydrogen bonding interactions in our monomers, the photopolymerization behavior and implicitly the conversion degree (DC) for some experimental adhesive formulations containing acid-modified BisGMA, commercial BisGMA (only in F1-F3), triethyleneglycol dimethacrylate and 2-hydroxyethyl methacrylate were examined by FTIR spectroscopy. The water effects on the photocrosslinked networks together with the
