A workflow is defined as a predefined set of work steps and partial ordering of these steps in any environment to achieve the expected outcome. Few studies have investigated the workflow of providers in a dental office. It is important to understand the interaction of dental providers with the existing technologies at point of care to assess breakdown in the workflow which could contribute to better technology designs. The study objective was to assess electronic dental record (EDR) workflows using time and motion methodology in order to identify breakdowns and opportunities for process improvement. A time and motion methodology was used to study the human-computer interaction and workflow of dental providers with an EDR in four dental centers at a large healthcare organization. A data collection tool was developed to capture the workflow of dental providers and staff while they interacted with an EDR during initial, planned, and emergency patient visits, and at the front desk. Qualitative and quantitative analysis was conducted on the observational data. Breakdowns in workflow were identified while posting charges, viewing radiographs, e-prescribing, and interacting with patient scheduler. EDR interaction time was significantly different between dentists and dental assistants (6:20 min vs. 10:57 min, p = 0.013) and between dentists and dental hygienists (6:20 min vs. 9:36 min, p = 0.003). On average, a dentist spent far less time than dental assistants and dental hygienists in data recording within the EDR.

Engineering, administrative, and work practice controls have been recommended for many years to minimize exposure to nitrous oxide during dental procedures. To better understand the extent to which these exposure controls are used, the NIOSH Health and Safety Practices Survey of Healthcare Workers was conducted among members of professional practice organizations representing dentists, dental hygienists and dental assistants. The anonymous, modular, web-based survey was completed by 284 dental professionals in private practice who administered nitrous oxide to adult and/or pediatric patients in the seven days prior to the survey. Use of primary engineering controls (i.e., nasal scavenging mask and/or local exhaust ventilation (LEV) near the patient's mouth) was nearly universal, reported by 93% and 96% of respondents who administered to adult (A) and pediatric (P) patients, respectively. However, adherence to other recommended precautionary practices were lacking to varying degrees, and were essentially no different among those administering nitrous oxide to adult or pediatric patients. Examples of work practices which increase exposure risk, expressed as percent of respondents, included: not checking nitrous oxide equipment for leaks (41% A; 48% P); starting nitrous oxide gas flow before delivery mask or airway mask was applied to patient (13% A; 12% P); and not turning off nitrous oxide gas flow before turning off oxygen flow to the patient (8% A; 7% P). Absence of standard procedures to minimize worker exposure to nitrous oxide (13% of all respondents) and not being trained on safe handling and administration of nitrous oxide (3%) were examples of breaches of administrative controls which may also increase exposure risk. Successful management of nitrous oxide emissions should include properly fitted nasal scavenging masks, supplemental LEV (when nitrous oxide levels cannot be adequately controlled using nasal masks alone), adequate general ventilation, regular

Coincidence of facial and dental midlines is one of the important goals in orthognathic-orthodontic treatment to achieve optimum facial aesthetics and good occlusal functions. Tools assisting diagnosis of facial midline are usually ruler or dental floss. These tools are usually hand held and hinder the global sight required in facial evaluation. Line laser device projects a steady narrow laser line and is commonly used in construction and carpentry to replace traditional chalk line tool. The authors take the advantages of line laser and incorporate it into facial evaluation in the authors' practice of single-splint orthognathic surgery.During June 2013 to May 2015, the authors used line laser device to evaluate facial and dental midlines in 28 patients of facial asymmetry requiring orthognathic surgery during consultation in office and intraoperative evaluation. The details of integrating this device to practice are described. All the patients showed improved facial symmetry and coincidence of facial and dental midlines after operation. Postoperative orthodontics were finished smoothly.Line laser is available from general utility stores and is safe to use according to laser safety regulation. From the authors' experiences, it is burden free to apply in facial and dental midlines evaluation and improves the practice.

This study describes a pilot project in which peer assisted learning (PAL) is used to teach dental clinical skills. A cluster randomised controlled trial compared opinions of Bachelor of Dental Surgery (BDS) students from peer-led groups versus staff-led groups in a clinical (impression taking) and a pre-clinical (handpiece skills) task. BDS5 (peer tutors) in their final year delivered teaching to BDS1 (tutees) for each task. Quantitative data from tutees and the peer tutors was gathered from questionnaires, along with open written comments. PAL was well received by both tutees and peer tutors. BDS1 tutees rated BDS5 peer tutors highly for delivery of information, and level of feedback. The tutees considered peer tutors more approachable and less intimidating than staff. Peer tutors reported their own knowledge had increased as a result of teaching. In a summative OSCE (objective structured clinical examination) four months following the teaching, no statistical significant difference between the performance of peer-led and staff-led groups was found at stations related to the subject matter in question. It is argued that PAL, as well as being a useful method of delivering subject-specific teaching, is able to contribute to the development of graduate attributes.

The Econometric Model of the the Dental Sector forecasts a broad range of dental sector variables, including dental care prices; the amount of care produced and consumed; employment of hygienists, dental assistants, and clericals; hours worked by dentists; dental incomes; and number of dentists. These forecasts are based upon values specified by the user for the various factors which help determine the supply an demand for dental care, such as the size of the population, per capita income, the proportion of the population covered by private dental insurance, the cost of hiring clericals and dental assistants, and relevant government policies. In a test of its reliability, the model forecast dental sector behavior quite accurately for the period 1971 through 1977. PMID:7461974

Computer-assisted navigational surgery enhances safety in dental implantology.

Science.gov (United States)

Ng, F C; Ho, K H; Wexler, A

2005-06-01

Dental implants are increasingly used to restore missing dentition. These titanium implants are surgically installed in the edentulous alveolar ridge and allowed to osteointegrate with the bone during the healing phase. After osseo-integration, the implant is loaded with a prosthesis to replace the missing tooth. Conventional implant treatment planning uses study models, wax-ups and panoramic x-rays to prefabricate surgical stent to guide the preparation of the implant site. The drilling into the alveolar ridge is invariably a "blind" procedure as the part of the drill in bone is not visible. Stereotactic systems were first introduced into neurosurgery in 1986. Since then, computer-assisted navigational technology has brought major advances to neuro-, midface and orthopaedic surgeries, and more recently, to implant placement. This paper illustrates the use of real-time computer-guided navigational technology in enhancing safety in implant surgical procedures. Real-time computer-guided navigational technology enhances accuracy and precision of the surgical procedure, minimises complications and facilitates surgery in challenging anatomical locations.

Working in a healthy work environment is the ultimate goal of every employee. Dentistry is a stressful career, and the reasons for dissatisfaction are numerous. The aim of this study was to determine the factors of work satisfaction in dental professionals of the Bosnia and Herzegovina Federation. A total of 134 dental professionals selected randomly from the Registry of Dental Chamber of Bosnia and Herzegovina Federation were included in the study. All of them filled out the Demographic Questionnaire and Job Satisfaction Scale (JSS). An increase in the influence of work on the quality of life as well as an increase in its frequency results in leaving the job and significantly reducing the overall job satisfaction. General dental practitioners are significantly more satisfied as compared with specialists. Significant predictors of the job satisfaction are employment status, type of the practice, and availability of dental assistants. General dental practitioners with a dental assistant employed at a private practice are more likely to be satisfied with their jobs. Employment status, practice type and availability of dental assistants are significant predictors of job satisfaction. General dental practitioners working in a private practice with a dental assistant are most likely to be satisfied.

This study examined the impact of expanded function allied dental personnel on the productivity and efficiency of general dental practices. Detailed practice financial and clinical data were obtained from a convenience sample of 154 general dental practices in Colorado. In this state, expanded function dental assistants can provide a wide range of reversible dental services/procedures, and dental hygienists can give local anesthesia. The survey identified practices that currently use expanded function allied dental personnel and the specific services/procedures delegated. Practice productivity was measured using patient visits, gross billings, and net income. Practice efficiency was assessed using a multivariate linear program, Data Envelopment Analysis. Sixty-four percent of the practices were found to use expanded function allied dental personnel, and on average they delegated 31.4 percent of delegatable services/procedures. Practices that used expanded function allied dental personnel treated more patients and had higher gross billings and net incomes than those practices that did not; the more services they delegated, the higher was the practice's productivity and efficiency. The effective use of expanded function allied dental personnel has the potential to substantially expand the capacity of general dental practices to treat more patients and to generate higher incomes for dental practices.

2016-06-01

Full Text Available Nowadays, the clinical skill learning in dental education has begun in pre-clinic, known as Clinical Skill Laboratory (CSL which needs human resources, many and expensive tools and manikins, and enough times for practise. One of the method used in CSL in dental education is PeerAssisted Learning (PAL defined as “the development of knowledge and skill through active help and support among status equals or match companions”. This paper aims is to explain the role of PAL method to improve the effectivity of CSL learning in dental education in preclinical stage. Reviewing on the relevant literatures regarding peer assisted learning on the implementation of the clinical skill laboratory in dental education. The effectivity of CSL learning needs close supervision and individual feedback, so enough tutors is important through the process. This PAL method considered to be helpfull with the increasing numbers of dental students and the limitation of staff faculty. This method is found feasible, well accepted by peer-tutors and students, and can be as effective as conventional learning method. This is also useful for peer-teacher because they more intrinsically motivated, have higher conceptual learning scores, and perceive themselves to be more actively engaged with the environment than students who learn in order to be tested.  However, there are several limitation of this method. The contact time between students and medical doctors may decrease significantlyand it does not seem to be generally qualified to transfer such complex procedures.It also needs peer-teachers training and a detailed manual. Questions concerning the cost-effectiveness and profitability of student tutor-guided technical skills training may thus arise. But one institution that implemented this method states that the majority of their tutors decided to continue their teaching activity in the skills lab and that these experienced tutors, in addition to established faculty staff

Mechanical and Thermal Properties of Dental Composites Cured with CAD/CAM Assisted Solid-State Laser

Full Text Available Over the last three decades, it has been frequently reported that the properties of dental restorative composites cured with argon laser are similar or superior to those achieved with conventional halogen and light emitting diode (LED curing units. Whereas laser curing is not dependent on the distance between the curing unit and the material, such distance represents a drawback for conventional curing units. However, a widespread clinical application of this kind of laser remains difficult due to cost, heavy weight, and bulky size. Recently, with regard to the radiation in the blue region of the spectrum, powerful solid-state lasers have been commercialized. In the current research, CAD (computer-aided design/CAM (computer-aided manufacturing assisted solid-state lasers were employed for curing of different dental restorative composites consisting of micro- and nanoparticle-reinforced materials based on acrylic resins. Commercial LED curing units were used as a control. Temperature rise during the photopolymerisation process and bending properties were measured. By providing similar light energy dose, no significant difference in temperature rise was observed when the two light sources provided similar intensity. In addition, after 7 days since curing, bending properties of composites cured with laser and LED were similar. The results suggested that this kind of laser would be suitable for curing dental composites, and the curing process does not suffer from the tip-to-tooth distance.

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

In the Netherlands, the Individual Health Care Professions Act (IHCP Act) allows dental students, amongst other non-qualified individuals, to work under certain conditions in a dental practice. The aim of the study was to determine how many dental students have part-time employment in dental practice and which professional tasks they carry out. We also asked the dental students their opinion about the IHCP Act. All the enrolled dental students at the Academic Centre for Dentistry Amsterdam (ACTA) in the Netherlands received a questionnaire by e-mail. Within 1 month, two reminders were sent. The response was 44% (427 students). Of the responding students, 71% had paid employment in addition to their study. Twenty-five per cent of all students worked in a dental practice, usually 8 h a week. Study year and age were positively related to working part-time in dental practice. Activities frequently performed were providing chair side assistance, giving oral hygiene instruction, fluoride applications, scaling and root planning. The self-reported knowledge about the IHCP Act was positively related to study year and working in a dental practice. Hardly any information about the requirements of the IHCP Act with regard to delegation of tasks was provided by the employer. Many Dutch dental students work in a dental practice, taking over a variety of tasks. Although the self-reported knowledge about the IHCP Act was relatively high, many dental students expressed the need for more detailed information about the legal aspects of their tasks.

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

Connor, Joseph P; Troendle, Karen

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.

Work assignments, delegation of tasks and job satisfaction among Danish dental hygienists.

Hach, M; Aaberg, K B; Lempert, S M; Danielsen, B

2017-08-01

Recent legislation in Denmark has made it possible for dentists to delegate their tasks to dental hygienists. Previous studies have shown that Danish dental hygienists primarily were performing assignments within their own work field. These assignments include prophylaxis or instructing patients in oral health care. However, studies have also shown that Danish dental hygienists performed dental nurse assignments such as chair-side assistance, unit cleaning and disinfection of instruments. The objectives of this study were to investigate (i) the range of work assignments performed by Danish dental hygienists, (ii) the types of dentist tasks performed by Danish dental hygienists and (iii) job satisfaction among Danish dental hygienists. Dental hygienists graduating in 2004-2007 were invited to participate in this study. Participants answered an email-distributed questionnaire. The questionnaire consisted of questions regarding job satisfaction, assignments performed, postgraduate course attendance, receiving assistance from a dental nurse and which work assignments Danish dental hygienists wish to perform in the future. The results of this study showed that 90% of Danish dental hygienists were satisfied with their job and 52% were performing dentists' tasks. Among dentists' tasks performed by Danish dental hygienists, invasive caries therapy was the most frequently performed task. The type of assignments performed by Danish dental hygienists today appears to be changing compared to previous studies. From initially performing prophylaxis and chair-side assistance for the dentist, Danish dental hygienists today are performing a wider range of tasks which includes dentists' tasks. © 2016 John Wiley & Sons A/S.

Armfield, Jason M; Ketting, Manon

2015-09-01

It has been proposed that avoidance of dental visits might be the main determinant of poor oral health outcomes in people with high dental anxiety (HDA). This study aimed to determine the predictors of dental avoidance among people with HDA and also whether these predictors differed from those found in people with lower dental anxiety (LDA). Study participants (n = 596; response rate = 41.1%) comprised a random cross-sectional sample of the Australian adult population who completed a mailed self-complete questionnaire containing items relating to the use and accessibility of dental services, trust in dental professionals, dental anxiety, dental experiences, self-perceived oral health, vulnerability-related perceptions of visiting the dentist, and psychological health. Multiple imputation was used to replace missing values and statistically significant variables in bivariate analyses were entered into a multivariable logistic generalized linear model. More than two-thirds of participants with HDA were currently avoiding or delaying a dental visit. Among people with HDA, dental avoidance was independently and significantly predicted by difficulty paying a $300 dental bill, having no or only little trust in the last-visited dentist, perceived treatment need and dental anxiety. Among people with LDA, only perceived treatment need and dental anxiety predicted avoidance. In addition to their high anxiety, a number of additional barriers to dental visiting were found for people with HDA. These barriers, especially cost and communication issues with dentists, need to be addressed to assist people with HDA obtain necessary, regular dental care. (c) 2015 APA, all rights reserved).

Hand dermatitis and symptoms from the fingers among Swedish dental personnel.

1998-01-01

Hand dermatitis among dental personnel has been an issue in recent years. Dental personnel manually handle polymer materials which are known to irritate skin, and also cause allergy. In addition, dental personnel wash their hands frequently, and use latex gloves, and are therefore at risk to develop hand dermatitis. To survey the occurrence of hand dermatitis among dental personnel, questionnaires were sent to all dental teams (dentist + chair assistant) working in the two northern Swedish counties. Referents were; researchers, teachers, and secretaries from a university and high schools, from the same geographical area. The response rate was 76% for dental teams, and 66% for referents. The results show that male dentists reported a significantly higher prevalence of hand dermatitis than male reference. In contrast to chair assistants and referents, dentists (both male and female) reported a higher extent of hand dermatitis on the left than on the right hand. There was an association between hand dermatitis among dental personnel and; age, eczema in childhood, and hay fever but, not with; sex, asthma, frequent washing of the hands, and glove use. Whitening of the fingers increased with increasing age among dental personnel. Pricking was also associated with frequent glove use. Pricking of the fingers was associated with sex, and 3.5 times more common among female dental personnel than male dentists. Numbness of the fingers, and finger pain was reported by more dentists than chair assistants and referents.

Fried, Jacquelyn L

2017-09-01

This executive summary for Section 5 of the "Advancing Dental Education in the 21 st Century" project addresses the current and future educational systems for dental assisting, dental hygiene, dental therapy, and dental laboratory technology. Nineteen experts prepared six background articles on the educational changes necessary for future roles and practices. The key issues addressed relate to delivery system changes, educational curricula, scopes of practice, regulatory measures, and the public's oral health. The major finding is that substantial reforms will be needed to adequately prepare allied oral health professionals for the changes anticipated in 2040. A reconsideration of current accreditation guidelines, more flexibility with scopes of practice, and an adherence to rigorous academic programs are essential elements for the future of these professions.

The virtual dental home: a critique.

Science.gov (United States)

Friedman, Jay W; Nash, David A; Mathu-Muju, Kavita R

2017-09-01

The Virtual Dental Home is a concept of the Pacific Center for Special Care of the Arthur A. Dugoni School of Dentistry in San Francisco. It is designed to improve access to dental care for underserved populations, specifically children and institutionalized adults. This article describes the development and implementation of the Virtual Dental Home, subsequently critiquing the concept. The criteria for a dental home are not met by the program. It is the equivalent of a traditional public oral health prevention and screening program, with the additional dimension of allowing dental hygienists and assistants to place interim glass ionomer restorations in dental cavities. The critique questions the need to insert a "cloud" dentist into the process. The routine utilization of radiographs is also challenged. The VDH not only lacks the attributes of a dental home, it has not been shown to be as efficient and effective as traditional programs staffed by dental hygienists and dental therapists. The article concludes by describing how programs utilizing dental therapists could address the deficiencies of the Virtual Dental Home, effectively improving access to oral health care for underserved populations. © 2017 American Association of Public Health Dentistry.

Two case examples of female dental patients, aged 56 and 24 years, who met the criteria for dental phobia according to the Phobia Checklist, illustrate the use of VRET in the dental setting. VRET that is used as a psychological treatment for dental fear and dental phobia can potentially be given by a non-specialist (for example dental assistant), thereby making it a cost-effective therapy for the treatment of dental phobia. Clinical relevance: This article is the first of its kind to demonstrate Virtual Reality Exposure Therapy (VRET) in the treatment of dental anxiety.

To investigate the knowledge and attitudes of Thai dental practitioners regarding patients with HIV, a cross-sectional study using self-administered questionnaires was conducted. The questionnaires requested demographic information and included questions evaluating the knowledge and attitude of dental practitioners towards HIV. The results were analyzed using Scheffe method for multiple comparisons at the 95 percent confidence level. Out of 1,200 questionnaires sent, 446 questionnaires were returned (response rate 37.2 percent). The subjects included final (sixth)-year dental students (11.9 percent), general dentists (29.1 percent), specialist dentists (15.5 percent), dental hygienists (30.5 percent), and dental assistants (13 percent). More than 80 percent of the dental practitioners correctly answered the questions testing their basic knowledge of HIV such as routes of transmission and common opportunistic infections. However, knowledge about HIV pathogenesis, complications, and advances in HIV management was lacking. Dental hygienists and dental assistants had statistically significant lower scores in knowledge about HIV than other groups. Sixty-seven percent of dental practitioners said they feel worried when treating patients with HIV, and 20.4 percent said they would deny treatment for patients with HIV if possible. While knowledge about HIV may be adequate among dental practitioners in Thailand, greater effort should be put into emphasizing positive attitudes towards patients with HIV.

To evaluate the implementation of quality assurance requirements for digital dental radiography in routine clinical practice. The results should be discussed by radiation protection authorities in the context of the relevant legal requirements and current debates on radiation protection. Two hundred digital dental radiographs were randomly selected from the digital database of the Department of Dentistry's Dental and Maxillofacial Surgery Clinic, Ulm University, and evaluated for various aspects of image quality and compliance with radiographic documentation requirements. The dental films were prepared by different radiology assistants (RAs) using one of two digital intraoral radiographic systems: Sirona Heliodent DS, 60 kV, focal spot size: 0.7 mm (group A) or KaVo Gendex 765 DC, 65 kV, focal spot size: 0.4 mm (group B). Radiographic justification was documented in 70.5% of cases, and the radiographic findings in 76.5%. Both variables were documented in the patient records as well as in the software in 14% of cases. Clinical documentation of the required information (name of the responsible dentist and radiology assistant, date, patient name, department, tube voltage, tube current, exposure time, type of radiograph, film size, department and serial number of the dental radiograph) was 100% complete in all cases. Moreover, the department certified according to DIN ISO 9001:2008 specifications demonstrated complete clinical documentation of radiographic justifications and radiographic findings. The entire dentition was visible on 83% of the digital films. The visible area corresponded to the target region on 85.7% of the digital dental radiographs. Seven to 8.5% of the images were classified as "hypometric" or "hypermetric". This study indicates that improvements in radiology training and continuing education fordentists and dental staff performing x-ray examinations are needed to ensure consistent high quality of digital dental radiography.

The success of any dental practice depends, among other factors, on the critical role of staff employees. In order to encourage desired staff behaviors, incentive systems can be designed for employee dentists, assistants/hygienists and managers. A survey of dental franchises was conducted in 1987 for the purpose of examining their incentive control systems. The specific incentives employed by these dental franchises for their employees are analyzed. The implications of these incentive systems used by dental franchise organizations for all dental practices are then discussed.

Dental and dental hygiene faculty members often do not provide consistent instruction in the clinical environment, especially in tasks requiring clinical judgment. From previous efforts to calibrate faculty members in calculus detection using typodonts, researchers have suggested using human subjects and emerging technology to improve consistency in clinical instruction. The purpose of this pilot study was to determine if a dental endoscopy-assisted training program would improve intra- and interrater reliability of dental hygiene faculty members in calculus detection. Training included an ODU 11/12 explorer, typodonts, and dental endoscopy. A convenience sample of six participants was recruited from the dental hygiene faculty at a California community college, and a two-group randomized experimental design was utilized. Intra- and interrater reliability was measured before and after calibration training. Pretest and posttest Kappa averages of all participants were compared using repeated measures (split-plot) ANOVA to determine the effectiveness of the calibration training on intra- and interrater reliability. The results showed that both kinds of reliability significantly improved for all participants and the training group improved significantly in interrater reliability from pretest to posttest. Calibration training was beneficial to these dental hygiene faculty members, especially those beginning with less than full agreement. This study suggests that calculus detection calibration training utilizing dental endoscopy can effectively improve interrater reliability of dental and dental hygiene clinical educators. Future studies should include human subjects, involve more participants at multiple locations, and determine whether improved rater reliability can be sustained over time.

Collaboration between dental practitioners and non-dental primary care providers has the potential to improve oral health care for people in rural and remote communities, where access to oral health services is limited. However, there is limited research on collaboration between these professional disciplines. The purpose of this paper was to explore the relationships between dental practitioners and non-dental primary care providers from rural and remote areas of Queensland and to identify strategies that could improve collaboration between these disciplines from the perspective of dental participants. Semi-structured interviews were conducted between 2013 and 2015 with visiting, local and regional dental practitioners (n = 12) who had provided dental services to patients from eight rural and remote Queensland communities that did not have a resident dentist. Participants were purposely recruited through a snow ball sampling technique. Interview data were analysed using thematic analysis with the assistance of QSR Nvivo v.10. Four major themes emerged from the data: (1) Communication between dental practitioners and rural primary care providers; (2) Relationships between dental and primary care providers; (3) Maintenance of professional dualism; (4) Strategies to improve interprofessional relationships (with subthemes: face to face meetings; utilisation of technology; oral health training for primary care providers; and having a community based oral health contact person). Participants observed that there was a lack of communication between the dental providers who saw patients from these rural communities and the primary care providers who worked in each community. This was attributed to poor communication, the high turnover of staff and the siloed behaviours of some practitioners. Visiting dental practitioners were likely to have stronger professional relationships with hospital nursing, administrative and allied health care staff who were often long term

The purpose of this study was to analyze data collected by the American Dental Association and the American Dental Education Association over the past two decades relating to changes in the number of women active in dental education and dental practice. The concept of a pipeline of women in dentistry was explored by analyzing predoctoral, postdoctoral, dental practice, and dental education domains for the inclusion of women. Statistical analyses show that there has been a consistent and progressive increase in the number of women in all stages of the pipeline. Over the past two decades, the number of female students attending and graduating from dental school has steadily increased. In 1984-85, 23.7 percent of all predoctoral students were women; in 2009-10, 45.1 percent were women. Similarly, in 1999, the graduating class was 35.3 percent women; in 2009, it was 46.1 percent women. In the postdoctoral domain, in 1996, 29.9 percent of all residents were women; in 2010, this had increased to 39.0 percent. In dental practice, the number of actively licensed women dentists in 1999 was 15.3 percent of the workforce; in 2010, this percentage had grown to 24.0 percent. In dental education, the number of women clinical faculty members has gradually increased from 669 in 1997-98 to 902 in 2007-08. Until 2000, there had been only two women deans and very few associate/assistant deans, with only sixteen in 1990. In 2000, major changes began with three women deans and seventy-two women associate/assistant deans. In 2009-10, there were 111 associate/assistant women deans and twelve women deans. These data show a progressive increase in the presence of women in all domains of dentistry, especially in leadership positions in dental education.

Hamedi-Sangsari, Adrien; Chinipardaz, Zahra; Carrasco, Lee

2017-10-01

The aim of this study was to compare outcome measurements of skeletal and dental expansion with bone-borne (BB) versus tooth-borne (TB) appliances after surgically assisted rapid palatal expansion (SARPE). This study was performed to provide quantitative measurements that will help the oral surgeon and orthodontist in selecting the appliance with, on average, the greatest amount of skeletal expansion and the least amount of dental expansion. A computerized database search was performed using PubMed, EBSCO, Cochrane, Scopus, Web of Science, and Google Scholar on publications in reputable oral surgery and orthodontic journals. A systematic review and meta-analysis was completed with the predictor variable of expansion appliance (TB vs BB) and outcome measurement of expansion (in millimeters). Of 487 articles retrieved from the 6 databases, 5 articles were included, 4 with cone-beam computed tomographic (CBCT) data and 1 with non-CBCT 3-dimensional cast data. There was a significant difference in skeletal expansion (standardized mean difference [SMD], 0.92; 95% confidence interval [CI], 0.54-1.30; P appliances. However, there was no significant difference in dental expansion (SMD, 0.05; 95% CI, -0.24 to 0.34; P = .03). According to the literature, to achieve more effective skeletal expansion and minimize dental expansion after SARPE, a BB appliance should be favored.

2013-01-01

Purpose The study reported here aimed to identify current sedation practice among general dental practitioners (GDPs) and specialist dental practitioners (SDPs) in Jordan in 2010. Methods Questionnaires were sent by email to 1683 GDPs and SDPs who were working in Jordan at the time of the study. The contact details of these dental practitioners were obtained from a Jordan Dental Association list. Details on personal status, use of, and training in, conscious sedation techniques were sought by the questionnaires. Results A total of 1003 (60%) questionnaires were returned, with 748 (86.9%) GDPs and 113 (13.1%) SDPs responding. Only ten (1.3%) GDPs and 63 (55.8%) SDPs provided information on the different types of treatments related to their specialties undertaken under some form of sedation performed by specialist and/or assistant anesthetists. Approximately 0.075% of the Jordanian population received some form of sedation during the year 2010, with approximately 0.054% having been treated by oral and maxillofacial surgeons. The main reason for the majority of GDPs (55.0%) and many SDPs (40%) not to perform sedation was lack of training in this field. While some SDPs (26.0%) indicated they did not use sedation because of the inadequacy of sedative facilities. Conclusion Within the limitations of the present study, it can be concluded that the provision of conscious sedation services in general and specialist dental practices in Jordan is inconsistent and inadequate. This stresses the great need to train practitioners and dental assistants in Jordan to enable them to safely and effectively perform all forms of sedation. PMID:23700369

Music interventions for dental anxiety.

Bradt, J; Teague, A

2018-04-01

Anxiety is a significant issue in the dental care of adults and children. Dental anxiety often leads to avoidance of dental care which may result in significant deterioration of oral and dental health. Non-pharmacological anxiety management interventions such as music listening are increasingly used in dental care. Although efficacy for music's anxiolytic effects has been established for pre-operative anxiety, findings regarding the use of music listening for dental anxiety are inconclusive, especially for children. The use of music for passive distraction may not be adequate for children and highly anxious adults. Instead, interventions offered by a trained music therapist may be needed to optimize music's anxiolytic impact. Music therapy interventions are individualized to the patient's presenting needs and geared at enhancing patients' active engagement in the management of their anxiety. Interventions may include (i) active refocusing of attention, (ii) music-guided deep breathing, (iii) music-assisted relaxation, and (iv) music-guided imagery. In addition, music therapists can teach patients music-based anxiety management skills prior to dental treatments, offer them the opportunity to express emotions related to the upcoming procedure, and help them gain a sense of control and safety. Clinical guidelines for the use of music listening by dental practitioners are offered. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

New leaders in dentistry: dental students.

Science.gov (United States)

Hammer, Dan

2010-01-01

Leadership opportunities for dental students have opened dramatically in recent decades because of the humanistic approach to education that shares responsibility for learning between students and faculty and that values mutual respect. Technology has also had an effect because it creates instant access and global communities. This new student leadership is most apparent in the American Student Dental Association (ASDA), which recently developed a White Paper on ethics, assisted in the establishment of Student Professionalism and Ethics Clubs at schools, and is developing a policy on unsupervised dental care. Students are also demonstrating leadership in research; in dual degrees that enhance teaching and policy; and in community service and outreach.

[Treatment-refractory-dental-extraction-associated pyothorax involving infection by 2 species of oral originated bacteria requires surgical debridement by video assisted thoracoscopic surgery (VATS)].

2008-09-01

Cases of septic pulmonary embolism (SPE) diagnosed clinically by CT after dental extraction rarely include verification of bacteria from the local infection site. We report the case of a 70-year-old man without background disease suffering severe pyothrax after dental extraction. We detected two species of oral bacteria from his pleural effusion. Treatment was so difficult that it required surgical debridement by video assisted thoracoscopic surgery (VATS), even after the appropriate administration of antibiotics. According to the American Heart Association (AHA) prophylaxis guidelines for preventing infective endocarditis indicate that it is uncommon to prescribe antibiotics to patients without background disease after dental extraction. No appropriate Japanese guidelines exist considering the prevention of SPE causing severe pyothorax as in our case. The hematogenous spread of bacteria such as SPE caused by sepsis after tooth extraction thus requires more attended careful consideration in clinical practice if patients are to be properly protected against potentially serious complications.

MIND--a five-state regional approach to continuing dental education.

Watkins, F

1975-08-01

MIND has finished two years of operation as a regional center for continuing dental education. The responses from viewing cards, and the number of credit hours given, indicate that approximately 20% of the potential audience participated in the course offerings. Previous experience from a two-year study in South Dakota has shown that there are three major factors that are essential for effective use of television as a dissemination medium. These are as follows: 1) the program should establish effective use of the communication system to maintain an audience; 2) the quality of thr programming material that is televised must be high; 3) the program should be televised on a regular basis to develop viewer habits or expectations. With a potential audience of 11,000 persons, MIND has had to depend heavily on a bulk-rate mailing system to communicate with members of the dental profession. This has caused problems such as reminders not being received on time, or being lost in the mail, or not being read, so that the individual is unaware that the courses are being telecast. Another problem of mailing system is maintaining an up-to-date list of addresses. The names and addresses of the dental assistants are impossible to keep up to date. We use the lists of licensed dentists and dental hygienists issued each July and a list of the certified dental assistants, which, of course, does not include all the dental assistants in our five-state area. A system providing more direct contact with the individual needs to be developed. Quality of televised courses is determined by the clinician's style of presentation as well as by the content and organization of the course material. The selection of dental information aimed toward the dentist in general practice results in loss of some members of the viewing audience, particularly specialists and generalpractitioners who have confined their practice to a particular area of dentistry. Quality is also judged by the technical aspects

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.

2016-01-01

This study has assessed the dental hygiene habits and problems of seafarers and their attitudes/ perceptions regarding oral hygiene using a dental hygiene/habits questionnaire. A research questionnaire on oral hygiene habits was prepared along with a summary of all the questions and sent to ships via e-mail by Centro Internazionale Radio Medico (CIRM) networks. CIRM, is the Italian Telemedical Maritime Assistance Service (TMAS), and represents the Centre with the largest number of seafarers assisted on board ships worldwide. CIRM proposed the questionnaire to all ships (n = 1,198) asking for medical advice from 1 July 2014 till 31 October 2014. Two dental professionals were involved in the development and analysis of the questionnaire. Seafarers are at risk of several dental health problems due to their oral hygiene and dietary habits, smoking and alcohol consumption, poor oral hygiene knowledge and motivation. Dietary habits during voyages were also questionable and seafarers consume food rich in fermentable carbohydrates, which is a major risk factor for dental caries. Seafarers need better oral hygiene education and care to enable them to manage their oral health in a better way. Life at the sea, under challenging circumstances is not without stress, that is why it is important that seafarers are given complete information about correct oral hygiene protocols and dental hygiene and the advantages for their health of keeping a healthy mouth.

Medical-dental collaboration is essential for improving resource efficiency and standards of care. However, few studies have been conducted on it. This study aimed to investigate the attitude and awareness of medical and dental students about collaboration between medical and dental practices in Hong Kong. All medical and dental students in Hong Kong were invited to complete a questionnaire survey at their universities, hospitals and residential halls. It contained 8 questions designed to elicit their attitudes about the collaboration between medical and dental practice. Students were also asked about their awareness of the collaboration between dentistry and medicine. The questionnaires were directly distributed to medical and dental students. The finished questionnaires were immediately collected by research assistants on site. A total of 1,857 questionnaires were distributed and 809 (44%) were returned. Their mean attitude score (SD) towards medical-dental collaboration was 6.37 (1.44). Most students (77%) were aware of the collaboration between medical and dental practice in Hong Kong. They considered that Ear, Nose & Throat, General Surgery and Family Medicine were the 3 most common medical disciplines which entailed collaboration between medical and dental practice. In this study, the medical and dental students in general demonstrated a good attitude and awareness of the collaboration between medical and dental practice in Hong Kong. This established an essential foundation for fostering medical-dental collaboration, which is vital to improving resource efficiency and standards of care.

This study examines predictors of transnational dental care utilization, or the use of dental care across national borders, over a 4-year period among immigrants to Canada. Data from the Longitudinal Survey of Immigrants to Canada (LSIC, 2001-2005) were used. Sampling and bootstrap weights were applied to make the data nationally representative. Bivariate and multiple logistic regression analyses were applied to identify factors associated with immigrants' transnational dental care utilization. Approximately 13% of immigrants received dental care outside Canada over a period of 4 years. Immigrants lacking dental insurance (OR = 2.05; 95% CI: 1.55-2.70), those reporting dental problems (OR = 1.45; 95% CI: 1.12-1.88), who were female (OR = 1.59; 95% CI: 1.22-2.08), aged ≥ 50 years (OR = 2.30; 95% CI: 1.45-3.64), and who were always unemployed (OR = 1.70; 95% CI: 1.20-2.39) were more likely to report transnational dental care utilization. History of social assistance was inversely correlated with the use of dental services outside Canada (OR = 0.48; 95% CI: 0.30-0.83). It is estimated that roughly 11 500 immigrants have used dental care outside Canada over a 4-year period. Although transnational dental care utilization may serve as an individual solution for immigrants' initial barriers to accessing dental care, it demonstrates weaknesses to in-country efforts at providing publicly funded dental care to socially marginalized groups. Policy reforms should be enacted to expand dental care coverage among adult immigrants. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

2004-10-01

Navigation-guided surgery has recently been introduced into various surgical disciplines, including oral and maxillofacial surgery. Since the advent of dental implants, dental computed tomography (CT) scans have been used as a diagnostic tool for preoperative planning, but not as part of the surgical phase. This article explains the principles of computer-assisted surgery and describes the use of a computer-guided navigation system in dental implantology. The system uses preoperative dental CT scans for planning and as an integral part of the surgical procedure. This system allows continuous intraoperative coordination of the implantation phase with the preoperative plan, optimizing the accuracy of implant surgery. Deviations from the planned location of the implants are minimal. Several cases are discussed.

In South Korea, the number of cases of dental treatment for the disabled is gradually increasing, primarily at regional dental clinics for the disabled. This study investigated pediatric patients at a treatment clinic for the disabled within a university hospital who received dental treatment under general anesthesia. This data could assist those that provide dental treatment for the disabled and guide future treatment directions and new policies. This study was a retrospective analysis of 263 cases in which patients received dental treatment under general anesthesia from January 2011 to May 2016. The variables examined were gender, age, reason for anesthesia, type of disability, time under anesthesia, duration of treatment, type of procedure, treatment details, and annual trends in the use of general anesthesia. Among pediatric patients with disabilities who received dental treatment under general anesthesia, the most prevalent age group was 5-8 years old (124 patients, 47.1%), and the primary reason for administering anesthesia was dental anxiety or phobia. The mean time under anesthesia was 132.7 ± 77.6 min, and the mean duration of treatment was 101.9 ± 71.2 min. The most common type of treatment was restoration, accounting for 158 of the 380 treatments performed. Due to increasing demand, the number of cases of dental treatment performed under general anesthesia is expected to continue increasing, and it can be a useful method of treatment in patients with dental anxiety or phobia.

O'Callaghan, Michael G

2012-05-01

"Human trafficking" is a term for a modern form of slavery. It is a criminal human rights violation and a significant health issue. Dental professionals can assist in recognizing victims of trafficking. The author conducted a PubMed search of the English-language literature through May 2011, which yielded no articles meeting the search criteria "dentistry" and "human trafficking prostitution." Given these results, the author reviewed articles published in medical journals, reports from both governmental and nongovernmental agencies and lay literature. The author examines the present state of human trafficking and provides information--including specific questions to ask--to help dentists identify victims. In addition, the author suggests means of notifying authorities and assisting trafficking victims. He also examines the health care needs of these patients. Human trafficking is a global problem, with thousands of victims in the United States, including many women and children. Dentists have a responsibility to act for the benefit of others, which includes detecting signs of abuse and neglect. Dental professionals are on the front lines with respect to encountering and identifying potential victims who seek dental treatment. Dentists can combat human trafficking by becoming informed and by maintaining vigilance in their practices.

Anesthetic exposure and health of dental personnel, 1 June 1978-30 November 1980

Energy Technology Data Exchange (ETDEWEB)

Cohen, E.N.

1980-01-01

An epidemiologic survey was conducted to determine possible health hazards in the dental profession, with particular attention being given to the results of exposure to anesthetic gases. The survey contacted 30,650 dentists and 30,547 chairside assistants who were subsequently grouped according to exposure to inhalation anesthetics in the dental operatory during the course of their employment experience. An increase in liver disease 1.7 above that expected was noted in male dentists heavily exposed to anesthetics, combined with a 1.2 fold increase for kidney disease and 1.9-fold increase for neurological disease. The spontaneous abortion rate in wives of male dentists was 1.5-fold higher than expected. Occupational exposure to anesthetics, either direct or indirect, was associated with significant increases in spontaneous abortion over control levels during the first and second trimester of pregnancy. Women who smoked during pregnancy showed increased risk of spontaneous abortion, with a 27% increase occurring in dental assistants and a 21% increase in wives of dentists. A 34% increased risk of babies having congenital abnormalities was noted among smoking dental assistants.

This study aimed to (1) measure the degree of patient satisfaction among the clinical and nonclinical dental services offered at specialty dental centers and (2) investigate the factors associated with the degree of overall satisfaction. Four hundred and ninety-seven participants from five dental centers were recruited for this study. Each participant completed a self-administered questionnaire to measure patient satisfaction with clinical and nonclinical dental services. Analysis of variance, t-tests, a general linear model, and stepwise regression analysis was applied. The respondents were generally satisfied, but internal differences were observed. The exhibited highest satisfaction with the dentists' performance, followed by the dental assistants' services, and the lowest satisfaction with the center's physical appearance and accessibility. Females, participants with less than a bachelor's degree, and younger individuals were more satisfied with the clinical and nonclinical dental services. The stepwise regression analysis revealed that the coefficient of determination (R (2)) was 40.4%. The patient satisfaction with the performance of the dentists explained 42.6% of the overall satisfaction, whereas their satisfaction with the clinical setting explained 31.5% of the overall satisfaction. Additional improvements with regard to the accessibility and physical appearance of the dental centers are needed. In addition, interventions regarding accessibility, particularly when booking an appointment, are required.

The poor oral health of nursing home residents is the cause of substantial morbidity and has major implications relating to health care policy. The aim of this study was to measure dental caries experience in Australians living in nursing homes, and investigate associations with resident characteristics. Clinical dental examinations were conducted on 243 residents from 19 nursing homes in Melbourne. Resident characteristics were obtained from nursing home records and interviews with residents, family and nursing home staff. Two dental examiners assessed coronal and root dental caries using standard ICDAS-II criteria. Residents were elderly, medically compromised and functionally impaired. Most required assistance with oral hygiene and professional dental care was rarely utilized. Residents had high rates of coronal and root caries, with a mean 2.8 teeth with untreated coronal caries and 5.0 root surfaces with untreated root caries. Functional impairment and irregular professional dental care were associated with higher rates of untreated tooth decay. There were no significant associations with medical conditions or the number of medications taken. Nursing home residents have high levels of untreated coronal and root caries, particularly those with high needs due to functional impairment but poor access to professional services. © 2014 Australian Dental Association.

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

The contact details of these dental practitioners were obtained from a Jordan Dental Association list. Details on personal status, use of, and training in, conscious sedation techniques were sought by the questionnaires.Results: A total of 1003 (60% questionnaires were returned, with 748 (86.9% GDPs and 113 (13.1% SDPs responding. Only ten (1.3% GDPs and 63 (55.8% SDPs provided information on the different types of treatments related to their specialties undertaken under some form of sedation performed by specialist and/or assistant anesthetists. Approximately 0.075% of the Jordanian population received some form of sedation during the year 2010, with approximately 0.054% having been treated by oral and maxillofacial surgeons. The main reason for the majority of GDPs (55.0% and many SDPs (40% not to perform sedation was lack of training in this field. While some SDPs (26.0% indicated they did not use sedation because of the inadequacy of sedative facilities.Conclusion: Within the limitations of the present study, it can be concluded that the provision of conscious sedation services in general and specialist dental practices in Jordan is inconsistent and inadequate. This stresses the great need to train practitioners and dental assistants in Jordan to enable them to safely and effectively perform all forms of sedation.Keywords: Jordan Dental

Dental Education in Veterinary Medicine

Full Text Available Periodontal disease is among the most prevalent canine dis-eases affecting over 75% of dogs. Strengthening of the human-animal bond and the increasing education of the aver-age pet owner, have fostered a heightened awareness of periodontal care in dogs and cats. Industry support has further assisted the small animal veterinarian in providing quality dental treatments and prevention. As recently as the 1990’s, veterinary curriculums contained little or no dental training. That trend is changing as nearly every one of the 28 US Colleges of Veterinary Medicine offers some level of small animal dentistry during the four-year curriculum. Primary areas of focus are on client education, the treatment of periodontal disease, dental prophylaxis, dental radiology, endodontics, exodontics and pain control. Students receive instruction in dental anatomy during their di-dactic curriculum and later experience clinical cases. Graduate DVMs can attend a variety of continuing education courses and even choose to specialize in veterinary dentistry in both small animals and horses. Through the efforts of organizations such as the American Veterinary Dental So-ciety, The American Veterinary Dental College and The Academy of Veterinary Dentistry, many veterinarians have been able to advance their skills in dentistry and improve animal welfare. Increasing ex-pectations of the pet-owning public coupled with the recent advancements of training opportunities available for vete-rinary students, graduate DVMs and certified veterinary technicians make veterinary dentistry an emerging practice-builder among the most successful small animal hospitals.

2017-10-01

Dental and dental hygiene clinical faculty members often do not provide consistent instruction, especially since most procedures involve clinical judgment. Although instructional variations frequently translate into variations in student performance, the effect of inconsistent instruction is unknown, especially related to ergonomics. The aim of this study was to determine whether photography-assisted calibration training would improve interrater reliability among dental hygiene faculty members in ergonomics evaluation. The photography-assisted ergonomics calibration program incorporated features to improve accessibility and optimize the quality of the training. The study used a two-group repeated measures design with a convenience sample of 11 dental hygiene faculty members (eight full-time and three part-time) during the autumn 2016 term at one U.S. dental school. At weeks one and seven, all participants evaluated imaged postures of five dental students using a modified-dental operator posture assessment instrument. During weeks three and five, training group participants completed calibration training using independent and group review of imaged postures. All pre-training and post-training evaluations were evaluated for interrater reliability. Two-way random effects intraclass coefficient (ICC) values were calculated to measure the effects of the training on interrater reliability. The average measure of ICC of the training group improved from 0.694 with a 95% confidence interval (CI) of 0.001 to 0.965 (F(4,8)=3.465, p>0.05) to 0.766 with a 95% CI of 0.098 to 0.972 (F(4,8)=7.913, p<0.01). The average measure of ICC of the control group improved from 0.821 with a 95% CI of 0.480 to 0.978 (F(4,28)=7.702, p<0.01) to 0.846 with a 95% CI of 0.542 to 0.981 (F(4,28)=8.561, p<0.01). These results showed that the photography-assisted calibration training with the opportunity to reconcile different opinions resulted in improved agreement among these faculty members.

Current policy in Southeast Asian dental education focuses on high-quality dental services from new dental graduates and the free movement of dental practitioners across the region. The Southeast Asian Nations (ASEAN) Dental Councils have proposed the "Common Major Competencies for ASEAN General Dental Practitioners" to harmonize undergraduate dental education. This article discusses how the ASEAN competencies were developed and established to assist the development of general dental practitioners with comparable knowledge, skills, and attitudes across ASEAN. The competencies were developed through four processes: a questionnaire about current national oral health problems, a two-round Delphi process that sought agreement on competencies, a panel discussion by representatives from ASEAN Dental Councils, and data verification by the representatives after the meeting. Key themes of the ASEAN competencies were compared with the competencies from the U.S., Canada, Europe, Australia, and Japan. A total of 33 competency statements, consistent with other regions, were agreed upon and approved. Factors influencing the ASEAN competencies and their implementation include oral health problems in ASEAN, new knowledge and technology in dentistry, limited institutional resources, underregulated dental schools, and uneven distribution of dental practitioners. The ASEAN competencies will serve as the foundation for further developments in ASEAN dental education including policy development, curriculum revision, quality assurance, and staff development. Collaboration amongst stakeholders is essential for successful harmonization of ASEAN dental education.

optical magnifying devices such as magnification loupes are increasingly used in clinical practice and educational settings. However, scientific evidence to validate their benefits is limited. This study assessed the effect of dental magnification loupes on psychomotor skill acquisition during a preclinical operative dentistry course. the performance of first-year dental students was assessed during an Advanced Simulation Course (AS) using virtual reality-based technology (VRBT) training. The test group consisted of 116 dental students using magnification loupes (+MAG), while students not using them (-MAG, n = 116) served as the control. The following parameters were evaluated: number of successfully passing preparation procedures per course rotation, amount of time per tooth preparation, number of times students needed computer assistance and evaluation, and amount of time spent in the computer assistance and evaluation mode per procedure. Data were collected on each student through VRBT during the preparation procedure and stored on a closed network server computer. Unpaired t tests were used to analyze mean differences between the groups. In addition, student acceptance of magnification loupes was measured and evaluated through survey interpretation. +MAG students completed more preparations, worked faster per procedure, and used the computer-assisted evaluation less frequently and for shorter periods, therefore displaying greater overall performance. The survey revealed a high degree of student acceptance of using magnification. dental magnification loupes significantly enhanced student performance during preclinical dental education and were considered an effective adjunct by the students who used them.

Bleeding disorders in dental practice: A diagnostic overview

Directory of Open Access Journals (Sweden)

Abhirup Goswami

2014-01-01

Full Text Available Dental health care workers are increasingly called upon to provide quality dental care to individuals whose bleeding and clotting mechanisms have been altered by inherited or acquired diseases. This provides an opportunity for the dentist who is trained in the recognition of oral and systemic signs of altered hemostasis to assist in the diagnosis of the underlying condition. A number of dental procedures result in the risk of bleeding that can have serious consequences, such as severe hemorrhage or possibly death, for the patient with a bleeding disorder. Oral care providers must be aware of the impact of bleeding disorders on the management of their patients. These disorders must be recognized from history, clinical examinations, and laboratory investigations, if indicated, prior to surgical procedures including those in dental surgery to prevent bleeding related complications. Safe dental care may require consultation with the patient′s physician, systemic management, and dental treatment modifications. The purpose of this article is how to identify these patients with bleeding disorders.

Fatigue of dental ceramics.

Zhang, Yu; Sailer, Irena; Lawn, Brian R

2013-12-01

Clinical data on survival rates reveal that all-ceramic dental prostheses are susceptible to fracture from repetitive occlusal loading. The objective of this review is to examine the underlying mechanisms of fatigue in current and future dental ceramics. The nature of various fatigue modes is elucidated using fracture test data on ceramic layer specimens from the dental and biomechanics literature. Failure modes can change over a lifetime, depending on restoration geometry, loading conditions and material properties. Modes that operate in single-cycle loading may be dominated by alternative modes in multi-cycle loading. While post-mortem examination of failed prostheses can determine the sources of certain fractures, the evolution of these fractures en route to failure remains poorly understood. Whereas it is commonly held that loss of load-bearing capacity of dental ceramics in repetitive loading is attributable to chemically assisted 'slow crack growth' in the presence of water, we demonstrate the existence of more deleterious fatigue mechanisms, mechanical rather than chemical in nature. Neglecting to account for mechanical fatigue can lead to gross overestimates in predicted survival rates. Strategies for prolonging the clinical lifetimes of ceramic restorations are proposed based on a crack-containment philosophy. Copyright © 2013 Elsevier Ltd. All rights reserved.

In 2005, Public Act No. 161 (PA 161) was passed in Michigan, allowing dental hygienists to practice in approved public dental prevention programs to provide services for underserved populations while utilizing a collaborative agreement with a supervising dentist. The aims of this study were to assess how well dental and dental hygiene students and faculty members and practicing dental hygienists have been educated about PA 161, what attitudes and knowledge about the act they have, and how interested they are in additional education about it. University of Michigan dental and dental hygiene students and faculty members, students in other Michigan dental hygiene programs, and dental hygienists in the state were surveyed. Respondents (response rate) were 160 dental students (50%), 63 dental hygiene students (82%), 30 dental faculty members (26%), and 12 dental hygiene faculty members (52%) at the University of Michigan; 143 dental hygiene students in other programs (20%); and 95 members of the Michigan Dental Hygienists' Association (10%). The results showed that the dental students were less educated about PA 161 than the dental hygiene students, and the dental faculty members were less informed than the dental hygiene faculty members and dental hygienists. Responding dental hygiene faculty members and dental hygienists had more positive attitudes about PA 161 than did the students and dental faculty members. Most of the dental hygiene faculty members and dental hygienists knew a person providing services in a PA 161 program. Most dental hygiene students, faculty members, and dental hygienists wanted more education about PA 161. Overall, the better educated about the program the respondents were, the more positive their attitudes, and the more interested they were in learning more.

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

2006-07-01

Computer technology is increasingly used in practical training at universities. However, in spite of their potential, computer-assisted learning (CAL) and computer-assisted simulation (CAS) systems still appear to be underutilized in dental education. Advantages, challenges, problems, and solutions of computer-assisted learning and simulation in dentistry are discussed by means of MEDLINE, open Internet platform searches, and key results of a study among German dental schools. The advantages of computer-assisted learning are seen for example in self-paced and self-directed learning and increased motivation. It is useful for both objective theoretical and practical tests and for training students to handle complex cases. CAL can lead to more structured learning and can support training in evidence-based decision-making. The reasons for the still relatively rare implementation of CAL/CAS systems in dental education include an inability to finance, lack of studies of CAL/CAS, and too much effort required to integrate CAL/CAS systems into the curriculum. To overcome the reasons for the relative low degree of computer technology use, we should strive for multicenter research and development projects monitored by the appropriate national and international scientific societies, so that the potential of computer technology can be fully realized in graduate, postgraduate, and continuing dental education.

2015-07-01

Dental implants have become a popular option for treating partially dentate or edentulous patients. Information on dental implants is widely available in the public domain and is disseminated through industries and dental practitioners at various levels/disciplines. This qualitative study aimed to evaluate the public's information acquisition and their perceptions of dental implants and the effects of these on their care-seeking and decision making. A purposive sample of 28 adults were recruited to join six focus groups. To be eligible, one must be 35-64 years of age, had never been engaged in dentally related jobs, had at least one missing tooth, and had heard about dental implant but never received dental implant or entered into any dental consultation regarding dental implants. All of the focus groups discussions were transcribed verbatim and subjected to thematic content analysis following a grounded theory approach. Participants acquired information on dental implants through various means, such as patient information boards, printed advertisements, social media, and personal connections. They expected dental implants to restore the patients' appearance, functions, and quality of life to absolute normality. They regarded dental implants as a panacea for all cases of missing teeth, overestimated their functions and longevity, and underestimated the expertise needed to carry out the clinical procedures. They were deterred from seeking dental implant treatment by the high price, invasive procedures, risks, and complications. Members of the public were exposed to information of varying quality and had some unrealistic expectations regarding dental implants. Such perceptions may shape their care-seeking behaviours and decision-making processes in one way or another. The views and experiences gathered in this qualitative study could assist clinicians to better understand the public's perspectives, facilitate constructive patient-dentist communication, and contribute

The influence of socioeconomic factors and self-rated oral health on children's dental health assistance was assessed. This study followed a cross-sectional design, with a multistage random sample of 792 12-year-old schoolchildren from Santa Maria, a city in southern Brazil. A dental examination provided information on the prevalence of dental caries (DMFT index). Data about the use of dental service, socioeconomic status, and self-perceived oral health were collected by means of structured interviews. These associations were assessed using Poisson regression models (prevalence ratio; 95% confidence interval). The prevalence of regular use of dental service was 47.8%. Children from low socioeconomic backgrounds and those who rated their oral health as "poor" used the service less frequently. The distribution of the kind of oral healthcare assistance used (public/private) varied across socioeconomic groups. The better-off children were less likely to have used the public service. Clinical, socioeconomic, and psychosocial factors were strong predictors for the utilization of dental care services by schoolchildren.

Dental Calculus Arrest of Dental Caries.

Keyes, Paul H; Rams, Thomas E

An inverse relationship between dental calculus mineralization and dental caries demineralization on teeth has been noted in some studies. Dental calculus may even form superficial layers over existing dental caries and arrest their progression, but this phenomenon has been only rarely documented and infrequently considered in the field of Cariology. To further assess the occurrence of dental calculus arrest of dental caries, this study evaluated a large number of extracted human teeth for the presence and location of dental caries, dental calculus, and dental plaque biofilms. A total of 1,200 teeth were preserved in 10% buffered formal saline, and viewed while moist by a single experienced examiner using a research stereomicroscope at 15-25× magnification. Representative teeth were sectioned and photographed, and their dental plaque biofilms subjected to gram-stain examination with light microscopy at 100× magnification. Dental calculus was observed on 1,140 (95%) of the extracted human teeth, and no dental carious lesions were found underlying dental calculus-covered surfaces on 1,139 of these teeth. However, dental calculus arrest of dental caries was found on one (0.54%) of 187 evaluated teeth that presented with unrestored proximal enamel caries. On the distal surface of a maxillary premolar tooth, dental calculus mineralization filled the outer surface cavitation of an incipient dental caries lesion. The dental calculus-covered carious lesion extended only slightly into enamel, and exhibited a brown pigmentation characteristic of inactive or arrested dental caries. In contrast, the tooth's mesial surface, without a superficial layer of dental calculus, had a large carious lesion going through enamel and deep into dentin. These observations further document the potential protective effects of dental calculus mineralization against dental caries.

This case study reports the ongoing progress and results of a manpower development program to expand indigenous dental personnel at four levels in the Republic of the Marshall Islands. The program was designed to: 1) increase the number of Marshallese students who successfully complete dentistry training; 2) recruit and train a group of Marshallese high school graduates in dental assisting for service in new preventive outreach programs within the community; 3) enhance the dental training of health assistants providing primary medical care to outer islands away from the main population centers of Majuro and Ebeye; and 4) provide in-service training on tooth decay prevention for Head Start teachers. The program resulted in the training of one Marshallese dentist and two Marshallese dental therapist, 16 primary care health aides who received oral health training for work in the outer island dispensaries, and 200 Head Start and kindergarten teachers who completed in-service training in oral health. Additional expertise was shared with other United States Affiliated Pacific Islands (USAPI) to enhance the dental workforce throughout the Pacific.

Digital models: How can dental arch form be verified chairside?

Directory of Open Access Journals (Sweden)

Alana Tavares

Full Text Available ABSTRACT Introduction: Plaster dental casts are routinely used during clinical practice to access maxillary dental arch form and assist on fabrication of individualized orthodontic archwires. Recently introduced, digital model technology may offer a limitation for the obtainment of a dental physical record. In this context, a tool for dental arch form assessment for chairside use is necessary when employing digital models. In this regard, paper print of the dental arch seems thus to be useful. Methods: In the present study, 37 lower arch models were used. Intercanine and intermolar widths and dental arch length measurements were performed and compared using plaster dental casts, digital models and paper print image of the models. Ortho Insight 3D scanner was employed for model digitalization. Results: No statistically significant differences were noted regarding the measurements performed on the plaster or digital models (p> 0.05. Paper print images, however, showed subestimated values for intercanine and intermolar widths and overestimated values for dental arch length. Despite being statistically significant (p< 0.001, the differences were considered clinically negligible. Conclusion: The present study suggests that paper print images obtained from digital models are clinically accurate and can be used as a tool for dental arch form assessment for fabrication of individualized orthodontic archwires.

The present study aimed to determine the prevalence of dental pain during pregnancy and its association with sociodemographic factors and oral health conditions among 315 pregnant women in South Brazil. Participants were interviewed to obtain sociodemographic data, such as age, educational level, employment status, family income, and marital and parity status. Medical and dental histories were also collected, including the occurrence of dental pain and the use of dental services during pregnancy. Clinical examinations were performed to assess the presence of visible plaque and gingival bleeding and to calculate the decayed, missing, and filled teeth index. Means and standard deviations of continuous variables and frequencies and percentages of categorical variables were calculated. Independent variables were included in a multivariate logistic regression analysis. A total of 173 (54.9 %) pregnant women reported dental pain during pregnancy. After adjustment of the analysis, caries activity remained the main determinant of dental pain (odds ratio 3.33, 95 % CI 1.67-6.65). The prevalence of dental pain during pregnancy was high and the presence of caries activity was a determinant of dental pain. Moreover, access to oral health care was low, despite pregnant women's increased need for dental assistance.

To investigate if women compared with men dentists experience deferential treatment from their female nurses, what workplace strategies women use to manage chair-side assistance and to examine if these were country related. A convenience sample of 22 male and female dentists of different ages working in general dental practice in The Netherlands and Northern Ireland participated. The sample framework was determined by saturation of the concepts. All informants were interviewed in a clinical setting. The data was subjected to rigorous line by line coding in order to identify clusters of codes, themes and concepts. Three themes were identified. These were: experiencing deferential nursing assistance; adopting 'friendly-like' working strategies and adopting business-like, hierarchical working strategies. Gender differences were shown for each of the themes. Women rather than men made friends with their nurses and attempted to reduce status inequalities. This led to workplace strategy inconsistencies. This suggested that it was not the type of strategy adopted but the inconsistency with which it was implemented that caused difficulties between younger women dentists and their nurses. Training dental students and young graduates how to interact appropriately in the clinical situation and to appreciate the nurses' work status will assist in improving working relationships.

Objectives: To evaluate the dental anxiety level and the degree of acceptance of laser assisted pedodontic treatments from the children part. Also, we want to underline the advantages of laser use in pediatric dentistry, to make this technology widely used in treating dental problems of our children patients. Methods: Thirty pediatric dental patients presented in the Department of Pedodontics, University of Medicine and Pharmacy "Victor Babeş", Timişoara were evaluated using the Wong-Baker pain rating scale, wich was administered postoperatory to all patients, to assess their level of laser therapy acceptance. Results: Wong-Baker faces pain rating scale (WBFPS) has good validity and high specificity; generally it's easy for children to use, easy to compare and has good feasibility. Laser treatment has been accepted and tolerated by pediatric patients for its ability to reduce or eliminate pain. Around 70% of the total sample showed an excellent acceptance of laser dental treatment. Conclusions: Laser technology is useful and effective in many clinical situations encountered in pediatric dentistry and a good level of pacient acceptance is reported during all laser procedures on hard and soft tissues.

2005-07-01

To identify the advice given by piercing parlours prior to orofacial piercing and to determine how many dental practitioners see complications from orofacial piercings. Administered questionnaire to 19 piercing parlours and postal questionnaire to 400 dental practitioners in south-east Wales. Ninety-nine per cent of 227 dental practitioners in south-east Wales had treated patients with orofacial piercings, over three-quarters had seen a patient for a complication caused by the piercing, and over half (N=120) had treated a patient for a complication of piercing. Tongue (N=225) and lip (N=209) piercings were most frequently seen and the most commonly occurring complication was fractured or cracked teeth (N=176). Almost all practitioners wanted more information on orofacial piercing and its sequelae. All 19 piercing parlours in south-east Wales warned clients about pain following piercing and 18 mentioned swelling; only four discussed possible damage to teeth and none discussed the risk of airway obstruction. Despite the concerns of dental and medical professionals orofacial piercing remains popular and the complications it causes are frequently seen by dental practitioners. There is a need for literature to assist both dental practitioners and piercers in advising and safeguarding patients.

Whereas the reduction of ionizing radiation hazard to the operators and the patients is recommended by the International Commission on Radiological Protection (ICRP) No. 9 and No. 16 for the application of radiographic diagnoses in the medical treatment, the authors sent questionnaires to 1884 dentists in practice in Fukuoka and Yamaguchi prefectures with the intent of investigating how much is understood about the x-ray protection by those practitioners. 450 replies thus obtained are analized as follows: 98.4% of the dental clinics are equipped with the dental x-ray units, but the understanding of the x-ray protection was not sufficient to nearly 60% of the dentists and assistants and that for the patients was seen in only 12.4% of them. The dentists who replied they were not aware of the ICRP publications amount to 62.4%. From these results, urgent need is felt for immediate through student education and refreshing training for the dental practitioners about the importance of ionizing radiological protection. (auth.)

The future of education and training in dental technology: designing a dental curriculum that facilitates teamwork across the oral health professions.

Science.gov (United States)

Evans, J; Henderson, A; Johnson, N

2010-03-13

Teamwork is essential for the provision of contemporary, high quality oral health care. Teamwork skills need to be taught and learnt and therefore ought to be one of the core competencies in all dental education programmes: dentistry, oral health therapy, dental technology and dental assisting. Currently, lack of opportunities for collaborative learning and practice within educational establishments, and in the practising professions, hamper the development of effective teamwork. For students across oral health care, learning 'together' requires positive action for teamwork skills to be developed. Interprofessional curricula need to be formally developed, based on evidence from the wider education literature that demonstrates how to maximise the engagements needed for teamwork in practice. Rigorous study of interprofessional education within dentistry and oral health is in its infancy. Anecdotal evidence indicates that dental technology students who experience an interprofessional curriculum are better prepared for collaborative practice. Formalised interprofessional education is posited as an effective strategy to improve interactions among oral health professionals leading to improved patient care. This paper reviews the extant literature and describes the approach currently being trialled at Griffith University.

Simon-Rusinowitz, L

1988-01-01

A personnel management problem exists within dental public health that interferes with its mission of improving the nation's oral health. A major cause of this problem may be that many administrators who write position descriptions and hire professional staff are unaware of differences between clinical and public health dental practitioners. A marketing plan has been developed to address this lack of awareness about proper use of dental public health professionals. Its main goal is to establish more appropriate personnel and employment practices within dental public health. The expected outcomes of this plan could assist both recipients of dental public health services and members of the profession. The purpose of this article is to introduce the marketing strategy to dental public health professionals.

Prefabricated fibula free flap with dental implants for mandibular reconstruction.

Science.gov (United States)

Pauchet, D; Pigot, J-L; Chabolle, F; Bach, C-A

2018-03-02

Free fibula transplant is routinely used for mandibular reconstruction in head and neck cancer. Dental rehabilitation, the objective of mandibular reconstruction, requires the use of dental implants as supports for fixed or removable dentures. Positioning of fibular bone grafts and implants determines implant osseointegration and the possibilities of dental rehabilitation. Prefabrication of a fibula free flap with dental implants prior to harvesting as a free flap can promote implant osseointegration. The position of the implants must then be precisely planned. Virtual surgery and computer-assisted design and prefabrication techniques are used to plan the reconstruction and then reproduce this planning by means of tailored fibula and mandible cutting guides, thereby ensuring correct positioning of fibular bone fragments and implants. The prefabricated fibula free flap technique requires two surgical procedures (prefabrication and flap transfer) and precise preoperative planning. Prefabricated fibula free flap with dental implants, by improving the quality of osseointegration of the implants before flap transfer, extends the possibilities of prosthetic rehabilitation in complex secondary mandibular reconstructions.

Dental care during pregnancy is important for pregnant women and their children. Comprehensive guidelines for the provision of dental services for pregnant patients were published in 2006, but there is relatively little information about their use in actual practice. The aim of this study was to examine differences in knowledge and attitudes regarding dental care in pregnancy among dentists, dental hygienists, dental assistants, and nonclinical office staff. A secondary aim was to identify sources of influence on attitudes and knowledge regarding the guidelines. A survey was used to collect information from 766 employees of a Dental Care Organization based in Oregon; responses from 546 were included in the analyses reported here. Statistically significant differences in knowledge were found among the professional-role groups. Dentists and hygienists consistently answered more items correctly than did other respondents. Within all professional-role groups, knowledge gaps existed and were most pronounced regarding provision of routine and emergency services. Positive perceptions of providing dental care during pregnancy were associated with higher knowledge scores (z = 4.16, P education and continuing education for all dental office personnel are needed to promote the diffusion of current evidence-based guidelines for dental care during pregnancy. © 2012 American Association of Public Health Dentistry.

Full Text Available Abstract Background Percutaneous exposure incidents facilitate transmission of bloodborne pathogens such as human immunodeficiency virus (HIV, hepatitis C virus (HCV and hepatitis B virus (HBV. This study was conducted to identify the circumstances and equipment related to percutaneous injuries among dental professionals. Methods We used workers' compensation claims submitted to the Department of Labor and Industries State Fund during a 7-year period (1995 through 2001 in Washington State for this study. We used the statement submitted by the injured worker on the workers' compensation claim form to determine the circumstances surrounding the injury including the type of activity and device involved. Results Of a total of 4,695 accepted State Fund percutaneous injury claims by health care workers (HCWs, 924 (20% were submitted by dental professionals. Out of 924 percutaneous injuries reported by dental professionals 894 (97% were among dental health care workers in non-hospital settings, including dentists (66, 7%, dental hygienists (61, 18% and dental assistants (667, 75%. The majority of those reporting were females (638, 71%. Most (781, 87% of the injuries involved syringes, dental instruments (77, 9%, and suture needles (23%. A large proportion (90% of injuries occurred in offices and clinics of dentists, while remainder occurred in offices of clinics and of doctors of medicine (9%, and a few in specialty outpatient facilities (1%. Of the 894 dental health care workers with percutaneous injuries, there was evidence of HBV in 6 persons, HCV in 30 persons, HIV in 3 persons and both HBV and HVC (n = 2 exposure. Conclusion Out of hospital percutaneous injuries are a substantial risk to dental health professionals in Washington State. Improved work practices and safer devices are needed to address this risk.

Relieving idiopathic dental pain without drugs

Haryono Utomo

2011-06-01

Full Text Available Background: Teeth are commonly obvious source of orofacial pain. Sometimes the pain source is undetectable, thus called as idiopathic dental pain. Since dentist wants to alleviate or eliminate the pains with every effort in their mind, a lot of drugs could be prescribed. Moreover, it is make sense that endodontic treatment or even tooth extraction will be done. Unfortunately, endodontic treatment may also initiate neuropathic tooth pain that is caused by nerve extirpation, thus worsen the pain. Therefore, another cause of dental pain such as referred pain, periodontal disease, or stress which related to psychoneuroimmunology should be considered. In order to prevent from unnecessary drugs or invasive treatment such as root canal treatment and extraction, correct diagnosis and preliminary non-invasive therapies should be done. Purpose: This review elucidates several therapies that could be done by dentists for relieving idiopathic dental pain which includes massage, the “assisted drainage” therapy, modulation of psychoneuroimmunologic status and dietary omega-3. Reviews: Understanding the basic pathogenesis of pain may help in elucidating the effects of non-drug pain therapy such as muscle massage, the “assisted drainage” therapy, omega-3 and psychological stress relieving. These measures are accounted for eliminating referred pain, reducing proinflammatory mediators and relieving unwanted stress reactions consecutively. Psychological stress increases proinflammatory cytokines and thus lowered pain threshold. Conclusion: As an individual treatment, this non-drug therapy is useful in relieving idiopathic dental pain; nevertheless, if they work together the result could be more superior.Latar belakang: Gigi adalah suatu penyebab umum dari nyeri orofasial.

Dental Hygienist-Led Chronic Disease Management System to Control Early Childhood Caries.

Science.gov (United States)

Ng, Man Wai; Fida, Zameera

2016-06-01

Management of the complex chronic disease of early childhood caries requires a system of coordinated health care interventions which can be led by a dental hygienist and where patient self-care efforts are paramount. Even after receiving costly surgical treatment under general anesthesia in the operating room, many children develop new and recurrent caries after only 6-12 months, a sequela that can be prevented. This article describes the chronic disease management (CDM) of dental caries, a science-based approach that can prevent and control caries. In this article, we (1) introduce the concept of CDM of dental caries, (2) provide evidence that CDM improves oral health outcomes, and (3) propose a dental hygienist-led team-based oral health care approach to CDM. Although we will be describing the CDM approach for early childhood caries, CDM of caries is applicable in children, adolescents, and adults. Early childhood caries disease control requires meaningful engagement of patients and parents by the oral health care team to assist them with making behavioral changes in the unique context of their families and communities. The traditional dentist/hygienist/assistant model needs to evolve to a collaborative partnership between care providers and patients/families. This partnership will be focused on systematic risk assessment and behaviorally based management of the disease itself, with sensitivity toward the familial environment. Early pilot study results demonstrate reductions in the rates of new caries, dental pain, and referral to the operating room compared with baseline rates. Dental hygienists are the appropriate team members to lead this approach because of their expertise in behavior change and prevention. Copyright © 2016 The Authors. Published by Elsevier Inc.

Examination of jaws and teeth using Dental CT

International Nuclear Information System (INIS)

Nikolov, Vl.

2001-01-01

The aim of the present work was to establish a new method for dental imaging using Dental CT. Dental computer assisted tomography represents valuable addition to the diagnostics spectrum for planning oral and maxillofacial surgery. High resolution spiral CT and specially designed computer software allow representation of the jaws in different planes that are easy to match. The further allow the display of very small structures relevant to oral surgical interventions and reveal their spatial relationship in three dimensions. Dental CT is indicated, when clinical and conventional radiological techniques will not allow exact interpretation of the situation. It is modern oral implantology that primarily benefits from computer software enabling the assessment of surgical sites in the pre surgical phase. Such planning was not yet possible using two dimensional radiographic techniques. The dental-implantological part expects from radiography sharply defined contours of the external bony contours and the mandibular canal, exactly defined relation between slices and planes, no distortion in the ortho-radial planes, tools for reliable measurements of distances, angles and volumes, possibility to transmit pictures electronically or on hardcopy without loss of quality. Thus communication between dentists and radiologists may and must be intensified and supported by usage of modern telecommunication systems. (author)

Nevzatoğlu, Sirin; Küçükkeleş, Nazan

2014-05-01

The long-term treatment results of surgically-assisted facemask therapy were assessed by a comparison of the immediate protraction effects with those seen at five years review. Nine patients treated with a corticotomy-assisted maxillary protraction protocol were recalled five years following protraction. Cephalometric films taken before treatment (T0), immediately after maxillary protraction (T1) and five years after treatment (T2) were compared. The short-term results of surgically-assisted facemask therapy showed significant skeletal and soft tissue changes. After five years, the profile and dental relationships were well maintained and a cephalometric analysis revealed a stable vertical increase but only partially maintained soft tissue changes with loss of sagittal advancement. There was significant upper incisor proclination providing dental camouflage. Patients who are treated with corticotomy-assisted maxillary advancement should be very carefully selected. Assessment criteria include a low mandibular plane angle Class III patients who have severe maxillary retrognathism unable to be treated by conventional orthopaedic correction alone; patients who have almost completed growth and missed the chance of earlier orthopaedic correction, as well as patients who are not willing to accept bimaxillary orthognathic surgery, may be successfully treated.

Currently, about 46 million seniors, citizens over the age of 65, live in the United States. That number is expected to roughly double to more than 98 million by 2060, an increase from the current 15% of the population to 24%. Seniors are living longer and, due to advances in dental care and access to fluoridated water, keeping more of their teeth. As a result, many will be seeking to access services through a dental care delivery system that is already struggling to meet existing need. This article will describe emerging oral health workforce models, as well as interprofessional team approaches, that may help improve access to the growing population of senior citizens. The article will include discussions on dental therapists, dental hygienists, physicians, nurses, and physician assistants.

Stewart, Stacey; Hanning, Rhona

2012-01-01

The National Report Card on Osteoporosis Care (2008) announced the need for comprehensive approaches to risk reduction and improvement in the early diagnosis of osteoporosis. Dental research has suggested that low systemic bone-mineral density also occurs in alveolar bone, and people with osteoporosis may have an increased risk of tooth loss. Whether or not a causal link exists, both conditions share similar modifiable risk factors, including a role for calcium and vitamin D. The purpose of this paper was to critically examine the role calcium and vitamin D play in the relationship between osteoporosis and the risk of tooth loss. Scientific articles were obtained through PubMed, MEDLINE, CINAHL, AgeLine and Web of Science. Publications were restricted to those involving human subjects, and English-language articles on calcium and vitamin D. The search yielded 8 articles relating to osteoporosis and tooth loss that included calcium and vitamin D intake. Despite methodological concerns, the evidence shows a relationship between osteoporosis and tooth loss for people who have an inadequate intake of calcium and vitamin D. Adequate calcium intake positively influences optimal peak bone mass and may also assist in tooth retention in later life. The dental sector can assist with national prevention strategies for osteoporosis care.

2014-11-01

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.

2011-10-01

Full Text Available Abstract Background Considering the changes in dental healthcare, such as the increasing assertiveness of patients, the introduction of new dental professionals, and regulated competition, it becomes more important that general dental practitioners (GDPs take patients' views into account. The aim of the study was to compare patients' views on organizational aspects of general dental practices with those of GDPs and with GDPs' estimation of patients' views. Methods In a survey study, patients and GDPs provided their views on organizational aspects of a general dental practice. In a second, separate survey, GDPs were invited to estimate patients' views on 22 organizational aspects of a general dental practice. Results For 4 of the 22 aspects, patients and GDPs had the same views, and GDPs estimated patients' views reasonably well: 'Dutch-speaking GDP', 'guarantee on treatment', 'treatment by the same GDP', and 'reminder of routine oral examination'. For 2 aspects ('quality assessment' and 'accessibility for disabled patients' patients and GDPs had the same standards, although the GDPs underestimated the patients' standards. Patients had higher standards than GDPs for 7 aspects and lower standards than GDPs for 8 aspects. Conclusion On most aspects GDPs and patient have different views, except for social desirable aspects. Given the increasing assertiveness of patients, it is startling the GDP's estimated only half of the patients' views correctly. The findings of the study can assist GDPs in adapting their organizational services to better meet the preferences of their patients and to improve the communication towards patients.

2015-01-01

Dental caries continues to be the most prevalent bacteria-mediated non-contagious disease of humankind. Dental professionals assert the disease can be explained by poor oral hygiene and a diet rich in sugars but this does not account for caries free individuals exposed to the same risk factors. In order to test the hypothesis that amount of amelogenin during enamel development can influence caries susceptibility, we generated multiple strains of mice with varying levels of available amelogenin during dental development. Mechanical tests showed that dental enamel developed with less amelogenin is "weaker" while the dental enamel of animals over-expressing amelogenin appears to be more resistant to acid dissolution.

Examining the implications of dental treatment costs for low-income families.

Dental disease is concentrated among those with low socioeconomic status. Dental care is not publicly funded, and many Canadians must therefore make difficult financial choices when accessing dental care. Families who live in poverty have difficulty meeting even their most basic household needs, so dental treatment may not be affordable. The objective of this study was to understand how the cost of dental treatment affects the monthly budgets of families with low incomes. A chart review was conducted for a sample of 213 new patients examined at the Dalhousie University dental clinic over a 1-year period. Costs for proposed treatment plans were averaged. The patients" ability to pay for proposed treatment was examined in the context of various income scenarios. Two hundred and one patients were included in the final analysis. Dental treatment costs per patient averaged approximately $1600 for the year, with 42% of the planned treatment completed within the first year. The estimated monthly cost of completed treatment was $55. When the cost of a healthy diet was included in the monthly budget, it was determined that families in Nova Scotia with parents working for minimum wage and those receiving income assistance would experience a 100% shortfall for dental expenses. Low-income families in Nova Scotia were unable to afford both a nutritious diet and dental care. This is disturbing, given the links between a healthy diet and both overall health and dental health. An understanding of the significance of income shortfalls for those with low incomes, especially as they affect even basic nutritional needs, will help dental professionals to appreciate the seriousness of this issue and the difficulties that many Canadians face when trying to access basic dental care.

Rowland, Michael L; Bean, Canise Y; Casamassimo, Paul S

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.

2015-08-01

The people of Appalachia-West Virginia are culturally unique and are known to have oral health disparities. The purpose of this study was to evaluate dental fear in relation to delayed dental care as a factor influencing oral health behaviors within this culture. A cross sectional study design was used. Participants were urgent care patients in a university dental clinic. The sample included 140 adults over age 18 years. The Dental Fear Survey was used to determine dental fear level. Self-report of delayed dental care was provided by the participants. The Dental Fear Survey was dichotomized at score 33, with higher scores indicating dental fear. The prevalence of dental fear was 47.1% (n=66). There was a significant association of dental fear and dental delay. The unadjusted odds ratio was 2.87 (95% CI: 1.17, 7.04; p=0.021). The adjusted odds ratio was 3.83 (95%CI: 1.14, 12.82; p=0.030), controlling for tobacco use, perceived oral health status, pain, and last dental visit. A difference in dental delay between men and women was not present in this sample. The only significant variable in delayed dental care was dental fear. In Appalachia-West Virginia, there remains a high level of dental fear, despite advances in dental care, techniques, and procedures. Copyright © 2015 The American Dental Hygienists’ Association.

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

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

Interprofessional learning is a key component of today's health sciences education. Within a two-course series in dental pharmacology and therapeutics, a dental curriculum was revised to provide an interprofessional activity to expose dental students to a community pharmacy setting. The objectives of this activity were to augment students' learning about drug laws and prescription writing, as well as to foster interprofessional relationships and collaboration between pharmacists and dentists. Dental students were scheduled for one-hour observations at community pharmacies on campus. Learning objectives to guide this activity focused on demonstrating community pharmacy operating procedures, identifying ways to minimize prescribing and dosing errors, and understanding how pharmacists can assist dentists in prescribing. Following the observation, students were required to submit a written assignment, which accounted for 14 percent of their course grade. All 119 dental students (100 percent) enrolled in the course for the summers of 2012 and 2013 completed the activity. The average grade on the written assignment was 96.2 out of 100. At the end of the course, students were asked to participate in an online course evaluation survey, for which response rates were 37 percent and 43 percent for 2012 and 2013, respectively. The students rated the pharmacy observation activity favorably on this course evaluation. The pharmacy observation activity provided a successful interprofessional component to the didactic pharmacy course and was well received by the dental students as well as the community pharmacists.

The fact that a significant percentage of dentists employ dental hygienists raises an important question: Are dental practices that utilize a dental hygienist structurally and operationally different from practices that do not? This article explores differences among dental practices that operate with and without dental hygienists. Using data from the American Dental Association's 2003 Survey of Dental Practice, a random sample survey of U.S. dentists, descriptive statistics were used to compare selected characteristics of solo general practitioners with and without dental hygienists. Multivariate regression analysis was used to estimate the effect of dental hygienists on the gross billings and net incomes of solo general practitioners. Differences in practice characteristics--such as hours spent in the practice and hours spent treating patients, wait time for a recall visit, number of operatories, square feet of office space, net income, and gross billings--were found between solo general practitioners who had dental hygienists and those who did not. Solo general practitioners with dental hygienists had higher gross billings. Higher gross billings would be expected, as would higher expenses. However, net incomes of those with dental hygienists were also higher. In contrast, the mean waiting time for a recall visit was higher among dentists who employed dental hygienists. Depending on personal preferences, availability of qualified personnel, etc., dentists who do not employ dental hygienists but have been contemplating that path may want to further research the benefits and opportunities that may be realized.

On the use of pets to manage dental anxiety

Directory of Open Access Journals (Sweden)

Lora Manley

2016-01-01

Full Text Available Dental anxiety and fear can be a significant barrier to dental care, with symptoms ranging from feelings of unease to avoidance of care. The management of anxious patients is essential to improve their oral health. Triggers include sights, sounds, sensations, and smells of the equipment used in restorative procedures, and management should focus on controlling these factors. Recommendations for controlling these triggers include distraction and pharmacological interventions. In medicine, distractions include animal-assisted therapy, which proves an effective means of reducing anxiety levels. Studies have shown that interactions with live animals reduce self-reported anxiety more than distractions by either humans or magazines. The media also addresses the valuable role of emotional support by animals in boosting health and enhancing lives. In the past year, numerous news stories have reported regarding the use of certified therapy by dogs to comfort anxious patients in dental practices across the United States. Dogs serve to distract patients, drawing their focus away from dentistry, and generate a positive energy that enliven both the staff and the patients. The positive impact that therapy dogs have had on patients′ dental experiences cannot be overstated. The incorporation of pet anti-anxiety therapy is a safe, effective, and inexpensive approach to easing dental anxiety and has profound potential for improving oral health.

Using cigarettes and alternative tobacco products (ATPs) is associated with negative oral health outcomes, and dental health professionals are poised to help patients quit. The aim of this study was to determine dental, dental hygiene, and advanced dental students' use, knowledge, and beliefs about cigarettes and ATPs, including perceptions about their education in tobacco dependence treatment and counseling experience. All 1,783 students enrolled in the dental, dental hygiene, and postdoctoral dental programs at the New York University College of Dentistry were invited to participate in the survey in 2016. A total of 708 students at least partially completed the survey, for a response rate of 39.7%. In the results, 146 of the students (20.1%) reported ever using cigarettes, while 253 (35.7%) reported ever using any ATP. Regarding tobacco use intervention, the students reported they had not received enough training on ATPs, were neutral about cigarettes, and were somewhat confident and not so confident counseling a cigarette smoker or ATP user, respectively. By their fourth year, 77.8% of the dental students reported they had counseled someone to stop smoking cigarettes, but only 40.7% had counseled someone to stop using ATPs. Overall, all groups of students reported feeling more confident and had received more education on interventions for cigarettes than for ATPs (ptobacco and did not perceive they had received enough training on intervening with patients on use of cigarettes and ATPs. These findings call for a revised tobacco education curriculum for dental, dental hygiene, and advanced dental students, focused on building knowledge and confidence for promoting tobacco dependence treatment.

Today, dentists have a wide range of imaging modalities to choose from, the film based techniques, digital techniques, and the recent introduction of 3D volumetric or cone beam computed tomography (CBCT). The inherent design features of the new generation dental x-ray equipment has significantly improved over the years with no evidence of substandard x-ray units in operation. In dental facilities radiological workload is comparatively low, newer radiation equipments and accessories follow safety guidelines and employ better radiation protection measures for the patient and the operator. Dentists’ knowledge and expertise in radiation protection measures is good, enabling them to carry out riskfree radiation procedures in their practice. Therefore, the present study is aimed at assessing the need for dosimeters in current dental scenario.‘Is there currently a significant risk from dental radiography to merit the use of personal dosimetery in dental practice.’Dental health professionals (Oral radiologists) and radiographic assistants of fourteen dental colleges in Karnataka state participated in this questionnaire study. The questionnaire consisted of the following questions—the make, type, year of manufacture of radiographic machines used in their setup, number of radiographs made per day in the institution, type of receptors used, number of personnel at risk for radiation exposure, radiation protection measures used, regular monitoring by personal dosimeters, equivalent dosage readings for the past 12 months and whether the reading of thermoluminescent dosimeters (TLD) for any personnel had exceeded the recommended exposure value in the last 3 years.Dosimetry records of the radiology staff in the last three years shows doses no more than 1.50 mSv per year. The various institutions’ dose (person mSv) was in the range of 3.70 mSv–3.90 mSv.Personal monitoring for Dentists can be omitted in the dental colleges since the estimated dose of oral radiologists

To describe a simple technical evaluation of the access, security issues and uses of wireless networked PDAs in a dental clinic and report a pilot study investigating students' educational use of PDAs to access a Virtual Learning Environment (VLE) in a dental clinic. To undertake a technical evaluation of wireless networking to PDAs focusing on security issues, robustness of the system and accessibility particularly to educational resources. To evaluate the impact of using a PDA on undergraduate students in the dental clinic and at home. Part II describes the technical and educational evaluation of PDAs used by one group of 12 undergraduate fourth year students in the Primary Dental Care clinic. A cross over trial of six students with PDAs and six without was carried out during one semester of 12 weeks. Technical issues such as secure internet access using wireless connectivity were addressed. An assessment of the general and educational use and the students' attitudes towards using PDAs was undertaken using online questionnaires and focus group discussions. Over 90% of participants wanted PDAs as part of their dental kit. The potential of PDA use in dental training was demonstrated by a good to excellent response by over 75% of participants to having access to online support materials, particularly videos, being able to make notes for individual study and to keep a diary of their commitments to teaching sessions. Recreational use included a 100% good to excellent response to playing games and keeping a diary. The PDA proved to be a convenient and versatile mode of access to online education. Technical solutions enabled a substantial proportion of the functionality of WebCT (Web Course Tools) to be accessed by the students in a clinical environment. Both novice and experienced users were able to appreciate the use of the PDA and the less able considered that their ICT skills had improved. However, further research is needed to determine how students use a range of

Parkinson, Joseph W; Zeller, Gregory G

2017-03-01

Quality improvement and quality assurance programs are an integral part of providing excellence in health care delivery. The Dental Quality Alliance and the Commission on Dental Accreditation recognize this and have created standards and recommendations to advise health care providers and health care delivery systems, including dental schools, on measuring the quality of the care delivered to patients. Overall health care expenditures have increased, and the Affordable Care Act has made health care, including dentistry, available to more people in the United States. These increases in cost and in the number of patients accessing care contribute to a heightened interest in measurable quality improvement outcomes that reflect efficiency, effectiveness, and overall value. Practitioners and administrators, both in academia and in the "real world," need an understanding of various quality improvement methodologies available in order to select approaches that support effective monitoring of the quality of care delivered. This article compares and contrasts various quality improvement approaches, programs, and systems currently in use in order to assist dental providers and administrators in choosing quality improvement methodologies pertinent to their practice or institution.

Although a link between dietary changes, caries, and dental development has been observed, the literature provides little insight about this relationship. The aim of our study was to investigate the association between dental caries and dental development in a clinical sample of Albanian children and adolescents. In total, 118 children and adolescents, born between 1995 and 2004 and aged 6–15 years, were included. Dental caries in the deciduous dentition was assessed using the Decayed, Filled Teeth (dft) index and dental caries in the permanent dentition was assessed using the Decayed, Missing, Filled Teeth (DMFT) index. Dental development during the permanent dentition was determined using the Demirjian method. Linear and ordinal regression models were applied to analyze the associations of dental caries with dental age and developmental stages of each left mandibular tooth. Dental caries in the deciduous dentition, estimated as a median dft of 2.0 (90% range, 0.0–9.1), was significantly associated with lower dental age (β = -0.21; 90% CI: -0.29, -0.12) and with delayed development of the canine, both premolars, and the second molar. Untreated dental caries (dt) was associated with lower dental age (β = -0.19; 90% CI: -0.28, -0.10). Dental caries in the permanent dentition, estimated as a median DMFT of 1.0 (90% range, 0.0–8.0), was not significantly associated with dental age (β = 0.05; 90% CI: -0.04, 0.14). However, the DMFT was associated with the advanced stages of development of both premolars and the second molar. The untreated dental caries in the deciduous dentition delays the development of permanent teeth. PMID:29659350

Dental anxiety is still prevalent, despite advances in treatment, and affects the utilization of health care services. The purpose of this cross-sectional study was to determine if patients with different degrees of dental anxiety and pain undergoing emergency dental care have different stress reactions as measured by salivary cortisol. Seventy three patients completed the modified dental anxiety scale (MDAS), and described any previous dental traumatic experience. Their socio-demographic characteristics were also recorded. They also rated pain intensity on a 100 mm visual analogue scale (VAS). A saliva sample was collected before the procedure, and analyzed by enzyme immunoassay. Thirty patients were dentally anxious and forty one complained of pain. In this sample, dental anxiety was not related to gender, age, educational level and family income; however, a previous traumatic event was related to dental anxiety. There was no association between salivary cortisol concentrations and gender or dental anxiety. Patients with pain showed higher cortisol levels. When gathering patient information, the dentist should note patients' negative dental experiences in order to provide more effective, less traumatic treatment.

This baseline study aims to find out the evaluation of hygienic-sanitary conditions at the level of dental medicine cabinets through the verification of certain hygienic aspects. The study conducted consists in monitoring the hygienic/sanitary conditions at the level of 68 dental medicine cabinets (40 private cabinets and 28 school/university dental cabinets in Iasi county), using sheets for the assessment of the hygienic/sanitary conditions adapted from the control sheets of existing dental medicine cabinets at the level of DSP (Public Health Department) Iasi. The sheets for the assessment of the hygienic/sanitary conditions were evaluated by a specialized team and the results were i llustrated in the specific charts. At the level of all the dental cabinets the study revealed nonconformities regarding the means to carry out cleaning, disinfection operations, including the management of perilous waste, the control of medical personnel. An optimization of the hygienic-sanitary conditions at the level of dental medicine cabinets is still necessary, through participation to the activity of personnel training, who is directly involved in dental medical assistance.

The changing role of dental hygienists deserves dental and dental hygiene educators' attention. The first aim of this survey study was to assess University of Michigan dental, dental hygiene, and graduate students' and faculty members' perceptions of dental hygienists' roles; their attitudes and behaviors related to clinical interactions between dental and dental hygiene students; and perceived benefits of engaging dental hygiene students as peer teachers for dental students. The second aim was to assess whether one group of dental students' experiences with dental hygiene student peer teaching affected their perceptions of the dental hygiene profession. Survey respondents were 57 dental hygiene students in all three years of the program (response rate 60% to 100%); 476 dental students in all four years (response rate 56% to 100%); 28 dental and dental hygiene graduate students (response rate 28%); and 67 dental and dental hygiene faculty members (response rate 56%). Compared to the other groups, dental students reported the lowest average number of services dental hygienists can provide (p≤0.001) and the lowest average number of patient groups for which dental hygienists can provide periodontal care (ppeer teaching (ppeer teaching. After experiencing dental hygiene student peer teaching, the dental students' perceptions of dental hygienists' roles, attitudes about clinical interactions with dental hygienists, and perceived benefits of dental hygiene student peer teachers improved and were more positive than the responses of their peers with no peer teaching experiences. These results suggest that dental hygiene student peer teaching may improve dental students' perceptions of dental hygienists' roles and attitudes about intraprofessional care.

A four-tier problem-solving scaffold to teach pain management in dental school.

Science.gov (United States)

Ivanoff, Chris S; Hottel, Timothy L

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.

Witte, K.; Bodnar, W.; Schell, N.; Lang, H.; Burkel, E.

2014-01-01

A functional gradient material with eleven layers composed of a dental ceramics and titanium was successfully consolidated using field assisted sintering technique in a two-step sintering process. High energy X-ray diffraction studies on the gradient were performed at High Energy Material Science beamline at Desy in Hamburg. Phase composition, crystal unit edges and lattice mismatch along the gradient were determined applying Rietveld refinement procedure. Phase analysis revealed that the main crystalline phase present in the gradient is α-Ti. Crystallinity increases stepwisely along the gradient with a decreasing increment between every next layer, following rather the weight fraction of titanium. The crystal unit edge a of titanium remains approximately constant with a value of 2.9686(1) Å, while c is reduced with increasing amount of titanium. In the layer with pure titanium the crystal unit edge c is constant with a value of 4.7174(2) Å. The lattice mismatch leading to an internal stress was calculated over the whole gradient. It was found that the maximal internal stress in titanium embedded in the studied gradient is significantly smaller than its yield strength, which implies that the structure of titanium along the whole gradient is mechanically stable. - Highlights: • High energy XRD studies of dental ceramics–Ti gradient material consolidated by FAST. • Phase composition, crystallinity and lattice parameters are determined. • Crystallinity increases stepwisely along the gradient following weight fraction of Ti. • Lattice mismatch leading to internal stress is calculated over the whole gradient. • Internal stress in α-Ti embedded in the gradient is smaller than its yield strength

2016-01-01

Objectives There is considerable variation in dental services utilization across Appalachian counties, and a plausible explanation is that individuals in some geographical areas do not utilize dental care due to dental workforce shortage. We conducted an ecological study on dental workforce availability and dental services utilization in Appalachia. Methods We derived county-level (n = 364) data on demographic, socio-economic characteristics and dental services utilization in Appalachia from the 2010 Behavioral Risk Factor Surveillance System (BRFSS) using person-level data. We obtained county-level dental workforce availability and physician-to-population ratio estimates from Area Health Resource File, and linked them to the county-level BRFSS data. The dependent variable was the proportion using dental services within the last year in each county (ranging from 16.6% to 91.0%). We described the association between dental workforce availability and dental services utilization using ordinary least squares regression and spatial regression techniques. Spatial analyses consisted of bivariate Local Indicators of Spatial Association (LISA) and geographically weighted regression (GWR). Results Bivariate LISA showed that counties in the central and southern Appalachian regions had significant (p dental workforce availability, low percent dental services utilization). GWR revealed considerable local variations in the association between dental utilization and dental workforce availability. In the multivariate GWR models, 8.5% (t-statistics >1.96) and 13.45% (t-statistics >1.96) of counties showed positive and statistically significant relationships between the dental services utilization and workforce availability of dentists and dental hygienists, respectively. Conclusions Dental workforce availability was associated with dental services utilization in the Appalachian region; however, this association was not statistically significant in all counties. The findings suggest

Medina, Aida Carolina; Pozo, Rodrigo Del; de Cedres, Lucila Blanco

Dental agenesis is the most common developmental anomaly in humans, frequently associated with disorders in dental development and maturation. The purpose of this study is to determine radiographic variations in dental maturation in a group of Venezuelan children with dental agenesis. 1,188 panoramic radiographs, from healthy patients ages 5 to 12 years old were studied for agenesis of permanent teeth. Dental maturation was assessed by relative eruption and dental age according to Nolla, comparing children affected with dental agenesis to a stratified control group selected from the same population, excluding children with premature loss of primary teeth in the left quadrants and unclear radiographs. Descriptive analysis, and differences between means and medians (Student t test, Kruskall-Wallis p=0.05) were performed. Medians for Nolla stages were similar between groups, with delay in tooth formation in the agenesis group for second molars (p<0.05) and maxillary lateral incisors and second premolars. Dental age was significantly underestimated for both groups, -0.89 (±0.78) for the control group and -1.20 (±0.95) for the study group. Tooth eruption was similar between groups. Dental age was significantly delayed in Venezuelan children with dental agenesis, with variable significance for tooth formation of studied teeth.

The objective was to examine the relationship between dental pain (and its sequelae), and the extent of restorative care provided for primary molars, amongst children who regularly attend a general dental practitioner. A retrospective review of the clinical case notes of 677 children with caries who attended 50 general dental practitioners on a regular basis. Analyses were performed at the subject level. Logistic regression models were fitted for the dependent variables whether or not pain, a dental extraction for pain or sepsis and a course of antibiotics was recorded, after taking into account the proportion of carious teeth that were restored, the total number of carious teeth, the age caries was first recorded, gender and the clustering of the subjects within dental practices. Almost half of the children in the study (48%) were recorded as having at least one episode of pain. Total decay experience in the primary molars was a significant predictor of pain, extraction due to pain or sepsis and prescription of antibiotics. There was no significant association between the proportion of carious teeth restored and each of the three dependent variables. For those children who regularly attend their general dental practitioner and who have decay in their primary molars, dental pain is a common finding. Total decay experience in primary molars is the principal predictor of pain, extraction due to pain and the need for antibiotics, whilst the level of restorative care in the primary dentition is less important. In order to reduce the incidence of dental pain in young children, effective methods of preventing caries at the individual and public health levels need to be expanded.

The traditional, manual method of reproducing the dental arch form is prone to numerous random errors caused by human factors. The purpose of this study was to investigate the automatic acquisition of the dental arch and implement the motion planning and synchronized control of the dental arch generator of the multi-manipulator tooth-arrangement robot for use in full denture manufacture. First, the mathematical model of the dental arch generator was derived. Then the kinematics and control point position of the dental arch generator of the tooth arrangement robot were calculated and motion planning of each control point was analysed. A hardware control scheme is presented, based on the industrial personal computer and control card PC6401. In order to gain single-axis, precise control of the dental arch generator, we studied the control pulse realization of high-resolution timing. Real-time, closed-loop, synchronous control was applied to the dental arch generator. Experimental control of the dental arch generator and preliminary tooth arrangement were gained by using the multi-manipulator tooth-arrangement robotic system. The dental arch generator can automatically generate a dental arch to fit a patient according to the patient's arch parameters. Repeated positioning accuracy is 0.12 mm for the slipways that drive the dental arch generator. The maximum value of single-point error is 1.83 mm, while the arc-width direction (x axis) is -33.29 mm. A novel system that generates the dental arch has been developed. The traditional method of manually determining the dental arch may soon be replaced by a robot to assist in generating a more individual dental arch. The system can be used to fabricate full dentures and bend orthodontic wires. Copyright © 2012 John Wiley & Sons, Ltd.

Full Text Available Na primeira década do século XXI registra-se a ocorrência de dois movimentos importantes no âmbito da assistência odontológica pública e privada no Brasil: a entrada da saúde bucal na agenda de prioridades políticas do governo federal e o vigoroso crescimento na oferta de serviços odontológicos suplementares. Analisou-se a ocorrência desses fenômenos no município de São Paulo, mediante a busca de dados nos documentos oficiais e nas bases eletrônicas da Prefeitura Municipal de São Paulo, do Ministério da Saúde e da Agência Nacional de Saúde Suplementar (ANS, além de consulta à literatura científica. No período estudado, de janeiro de 2000 a dezembro de 2009, com base em indicadores como a Cobertura de Primeira Consulta Odontológica Programática e a Cobertura Populacional Potencial, verificaram-se percentuais que caracterizam baixa assistência pública e uma situação de grande distanciamento do princípio constitucional do acesso universal aos cuidados odontológicos. O crescimento do número de beneficiários de serviços suplementares, por meio de planos exclusivamente odontológicos e de outros planos foi expressivo em igual período, correspondendo a uma importante ampliação da cobertura populacional nesta modalidade assistencial. Constata-se que, comparativamente ao quadro geral nacional, a situação do município de São Paulo revela precariedade no acesso à assistência odontológica pública, com reduzida oferta de serviços a adultos e idosos. Considerando, ainda, as limitações do mercado de serviços suplementares para prover assistência odontológica para todos os brasileiros, reforça-se a necessidade de continuidade e expansão do Brasil Sorridente, que é a expressão programática da Política Nacional de Saúde Bucal.Two concomitant movements occur in the first decade of the XXI century within the private and public dental services in Brazil: the entrance of oral health on the agenda of

General anesthesia has been widely used in pediatric dentistry in recent years. However, there remain concerns about potential postoperative dental morbidity. The goal of this study was to identify the frequency of postoperative dental morbidity and factors associated with such morbidity in children. From March 2012 to February 2013, physically and mentally healthy children receiving dental treatment under general anesthesia at the Department of Pediatric Dentistry of the Chang Gung Memorial Hospital in Taiwan were recruited. This was a prospective and observational study with different time evaluations based on structured questionnaires and interviews. Information on the patient demographics, anesthesia and dental treatment performed, and postoperative dental morbidity was collected and analyzed. Correlations between the study variables and postoperative morbidity were analyzed based on the Pearson's chi-square test. Correlations between the study variables and the scale of postoperative dental pain were analyzed using the Mann-Whitney U test. Fifty-six pediatric patients participated in this study, with an average age of 3.34 ± 1.66 years (ranging from 1 to 8 years). Eighty-two percent of study participants reported postoperative dental pain, and 23% experienced postoperative dental bleeding. Both dental pain and bleeding subsided 3 days after the surgery. Dental pain was significantly associated with the total number of teeth treated, while dental bleeding, with the presence of teeth extracted. Patients' gender, age, preoperative dental pain, ASA classification, anesthesia time, and duration of the operation were not associated with postoperative dental morbidity. Dental pain was a more common postoperative dental morbidity than bleeding. The periods when parents reported more pain in their children were the day of the operation (immediately after the procedure) followed by 1 day and 3 days after the treatment.

Soon, Alistair S; Bush, Mary A; Bush, Peter J

2015-09-01

Recent research has shown that restorative dental materials can be recognized by microscopy and elemental analysis (scanning electron microscopy/energy dispersive X-ray spectroscopy and X-ray fluorescence; SEM/EDS and XRF) and that this is possible even in extreme conditions, such as cremation. These analytical methods and databases of dental materials properties have proven useful in DVI (disaster victim identification) of a commercial plane crash in 2009, and in a number of other victim identification cases. Dental materials appear on the market with ever expanding frequency. With their advent, newer methods of restoration have been proposed and adopted in the dental office. Methods might include placing multiple layers of dental materials, where they have different properties including adhesion, viscosity, or working time. These different dental materials include filled adhesives, flowable resins, glass ionomer cements, composite resins, liners and sealants. With possible combinations of different materials in these restorations, the forensic odontologist is now confronted with a new difficulty; how to recognize each individual material. The question might be posed if it is even possible to perform this task. Furthermore, an odontologist might be called upon to identify a victim under difficult circumstances, such as when presented with fragmented or incinerated remains. In these circumstances the ability to identify specific dental materials could assist in the identification of the deceased. Key to use of this information is whether these new materials and methods are detailed in the dental chart. Visual or radiographic inspection may not reveal the presence of a restoration, let alone the possible complex nature of that restoration. This study demonstrates another scientific method in forensic dental identification. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

How Research Training Will Shape the Future of Dental, Oral, and Craniofacial Research.

Science.gov (United States)

D'Souza, Rena N; Colombo, John S

2017-09-01

This is a critical time in the history of the dental profession for it to fully embrace the responsibility to safeguard its reputation as a learned profession. In this golden era of scientific and technological advances, opportunities abound to create new diagnostics, preventions, treatments, and cures to improve oral health. Dental schools are the largest national resource entrusted with the responsibility to educate, train, and retain oral health researchers who can leverage such technologies and research opportunities that will benefit the profession at large as well as patients. This article reemphasizes the theme that research training and scholarship must be inextricably woven into the environment and culture in dental schools to ensure the future standing of the profession. An overview of the history of support provided by the National Institutes of Health and National Institute of Dental and Craniofacial Research for the training and career development of dentist-scientists is presented. In addition, new data on the outcomes of such investments are presented along with a comparison with other health professions. This overview underscores the need to expand the capacity of a well-trained cadre of oral health researchers through the reengineering of training programs. Such strategies will best prepare future graduates for team science, clinical trials, and translational research as well as other emerging opportunities. The urgent need for national organizations like the American Dental Association, American Dental Education Association, and American Association for Dental Research to create new alliances and novel initiatives to assist dental schools and universities in fulfilling their research mission is emphasized. To ignore such calls for action is to disavow a valuable legacy inherited by the dental profession. This article was written as part of the project "Advancing Dental Education in the 21 st Century."

Purpose: To demonstrate the usefulness of Dental-MRT for imaging of anatomic and pathologic conditions of the mandible and maxilla. Methods: Seven healthy volunteers, 5 patients with pulpitis, 9 patients with dentigerous cysts, 5 patients after tooth transplantation and 12 patients with atrophic mandibles were evaluated. Studies of the jaws using axial T1- and T2-weighted gradient echo and spin echo sequences in 2D and 3D technique have been to performed. The acquired images were reconstructed with a standard dental software package on a workstation as panoramic and cross sectional views of the mandible or maxilla. Results: The entire maxilla and mandibula, teeth, dental pulp and the content of the mandibular canal were well depicted. Patients with inflammatory disease of the pulp chamber demonstrate bone marrow edema in the periapical region. Dentigerous cysts and their relation to the surrounding structures are clearly shown. After contrast media application marked enhancement of the dental pulp can be found. Conclusion: Dental-MRT provides a valuable tool for visualization and detection of dental diseases. (orig.) [de

The aim of this study was to assess the relationship between burnout, depressive symptoms and suicidal ideation in dental and dental hygiene students and to evaluate the influence of gender, programme type and year of study. Third- and fourth-year dental (DS) and first- and second-year hygiene students (DHS) completed the Patient Health Questionnaire (PHQ-9) and an abbreviated Maslach Burnout Inventory online as measures of depressive symptoms/suicidality and burnout, respectively. The statistical analyses included summary statistics and tests for intergroup comparisons (chi-square) to evaluate the influence of gender, programme type (DHS or DS) and year of study. Correlations between depression, suicidality and burnout were also conducted. A total of 32 dental hygiene and 119 dental students participated. 40% of the dental and 38% of the hygiene students met criteria for burnout. No differences were found between years or between programmes. Nine per cent of both dental and hygiene students were above the cut-off for moderate depressive symptoms, but there were no statistical differences between the third- and fourth-year dental and the first- and second-year hygiene students. Six per cent of the dental and 9% of the dental hygiene students were above the cut-off for clinically significant suicidal ideation, but there were no statistical differences between dental and hygiene students. There were no differences noted in the dental students based on gender for any of the measures. Depression was significantly associated with all three subscales of burnout. Suicidal ideation was only significantly related to the lack of personal accomplishment subscale of burnout. These findings suggest the need for introducing preventive measures for such affective states in dental and dental hygiene training programmes. © 2017 John Wiley & Sons A/S.

2015-01-01

Enamel cutting using dental handpieces is a critical process in tooth preparation for dental restorations and treatment but the machinability of enamel is poorly understood. This paper reports on the first quantitative assessment of the enamel machinability using computer-assisted numerical control, high-speed data acquisition, and force sensing systems. The enamel machinability in terms of cutting forces, force ratio, cutting torque, cutting speed and specific cutting energy were characterized in relation to enamel surface orientation, specific material removal rate and diamond bur grit size. The results show that enamel surface orientation, specific material removal rate and diamond bur grit size critically affected the enamel cutting capability. Cutting buccal/lingual surfaces resulted in significantly higher tangential and normal forces, torques and specific energy (pmachinability for clinical dental practice. Copyright © 2014 Elsevier Ltd.

1985-06-01

Area air and breathing-zone samples were analyzed for nitrous oxide at Dental Health Associates, Paoli, Pennsylvania on August 2, 1984. The evaluation was requested by a dental assistant because of general concern about the extent of nitrous oxide exposure, especially since the office was not equipped with a waste-anesthetic gas-scavenging system. The author recommends installing a waste anesthetic gas scavenging system with a dedicated exhaust. The nitrous oxide delivery and mixing system should be checked for leaks monthly and work practices for handling nitrous oxide should be improved.

This ross-sectional study involving 127 male prisoners evaluates the use of dental services and dental caries among Brazilian inmates. Data were collected by interview and clinical examination. Sociodemographic and sentencing information as well as use of dental services, self-reported dental morbidity, self-perception, and oral health impacts were investigated. The mean DMFT index value was 19.72. Of the components, the decayed component showed the highest mean value (11.06 ± 5.37). Statistically significant association was found between DMFTs with values from 22 to 32 and oral health satisfaction (p = 0.002), difficulty speaking (p = 0.024), shame of talking (p = 0.004) and smiling (p dental services, 80% had their last dental appointment less than one year ago, with most visits occurring in prison (80%), with restorative treatment (32%), followed by dental pain (26.4%), being the main reasons for such appointments. Most prisoners used dental services provided by the prison. Although restorative treatment has been the main reason for the use of dental services, "decayed" and "missing" components contributed to the high mean DMFT index.

Full Text Available Background  Whilst current asthma management is well-developed, there are still 5-10% uncontrolled asthma patients with unknown etiologies. However, its connection with oral focal infection is still uncertain. Therefore, a collaborated research for asthma management was conducted by pediatricians and dental practitioners. Within minutes after the "assisted drainage" therapy, a modification of healing root planning procedure, there is rapid improvement of respiratory function, ie., forced expiratory-volume one second (FEV1 in asthmatic children. This quick response usually achieved by oral inhalation. Objective To investigate the effectiveness of the assisted drainage therapy in the improvement of respiratory quality. Methods Fifteen asthmatic children were subjected to a longitudinal study for two weeks. In tbe first week they were instructed for al lergen avoidance only and the fOllowing one week was combined with tbe assisted drainage therapy, followed by  mental health education and dental plaque control therapy. Each s'ubject was af'sef'sed for respiratory quality with a computerized spirometer and blood sampling test. Paired t-test analysis was used for statistical analysis. Results Assisted drainage therapy was performed, within minutes FEV1 increased significantly (P= 0.001. Additionally, there were significant differences serum histamine (P= 0,001 pre and post treatment. Conclusions The assisted drainage therapy is effective as an adjuvant therapy for mild persistent asthma in children.

The various reasons for the current and projected shortages of dental faculty members in the United States have received much attention. Dental school deans have reported that the top three factors impacting their ability to fill faculty positions are meeting the requirements of the position, lack of response to position announcement, and salary/budget limitations. An electronic survey sent to program directors of specialty programs at all accredited U.S. dental schools inquired about the number of vacant positions, advertised vacant positions, reasons for not advertising, selection of advertising medium, results of advertising, and assistance from professional dental organizations. A total of seventy-three permanently funded full-time faculty positions were reported vacant, with 89.0 percent of these positions having been advertised in nationally recognized professional journals and newsletters. Networking or word-of-mouth was reported as the most successful method for advertising. The majority of those responding reported that professional dental organizations did not help with filling vacant faculty positions, but that they would utilize the American Dental Association's website or their specialty organization's website to post faculty positions if they were easy to use and update.

The prevalence and correlates of dental fear have been studied in representative population studies, but not in patients presenting for dental treatment. We hypothesized that dental fear among patients presenting at a large, urban college of dentistry would be similar to that of the population (e.g. 11% high dental fear, 17% to 35% moderate or higher fear) and that fear would be associated with avoidance of routine dental care, increased use of urgent dental care and poor oral health. Participants were 1070 consecutive patients at a large, urban dental care center. All patients completed a clinical interview, including demographics, medical history, dental history and presenting concerns, and behavioral health history. Patients were also asked to rate their dental anxiety/fear on a 1 (none) to 10 (high) scale. Over 20% of patients reported elevated anxiety/fear, of which 12.30% reported moderate and 8.75% high fear. Severity of dental anxiety/fear was strongly related to the likelihood of avoiding dental services in the past and related to myriad presenting problems. As hypothesized, the prevalence of moderate or higher fear in dental patients was considerable and closely matched that found in general population surveys. Thus, the 'dental home' is an ideal location to treat clinically significant dental anxiety/fear.

This cross sectional study was performed to evaluate dental ages and incidence of dental anomalies in children treated for acute lymphoblastic leukemia (ALL). A total of 25 ALL patient who passed at least 2 years of chemotherapy and 25 healthy sex and age matched children were evaluated. Dental age as well as dental anomalies in shape, size, number, and structure was recorded based on their panoramic radiographies which were taken for dental purposes. The number of dental anomalies significantly increased in ALL treated children. Seven ALL cases (28%) in compression to only one (4%) in control group had at least one dental anomaly. However, there was neither statistically significant differences between the mean of dental (p=0.32) and chronologic age (p=0.12) in both groups, nor between dental age of cases and control group (p=0.62).The age at the onset of treatment as well as treatment durations has not affected dental age and the incidence of dental anomalies significantly (pdental anomaly. Dental age, maturity, and development process however seems to be independent from chemotherapy.

The rehabilitative dental care is important for maintaining adequate nutrition, guarding against wasting syndrome and malnutrition among human immunodeficiency virus (HIV)-infected individuals. The aim of this study is to determine the Nigerian dental technology students' knowledge and misconceptions about HIV infection and their willingness to care for HIV-infected patients. This descriptive cross-sectional study of dental technology students of Federal School of Dental Therapy and Technology Enugu, Nigeria was conducted in 2010. Data was subjected to descriptive, non-parametric and parametric statistics using the statistical package for the social sciences (SPSS) version 17.0 (Chicago Illinois, USA). P 4.0% (8/198) of the respondents erroneous described HIV as harmless, self-limitation and antibiotics responsive infection respectively. Of the respondents, 78.8% (156/198) and 83.3% (165/198) of them expressed willingness to care for HIV-infected patients and expressed need for training in the clinical care of HIV-infected patients respectively. Overall, the respondents opined that the dental therapists are the most suitable dental professional to pass HIV-related information to patients in the dental setting ahead of dentists and dental surgery assistants. The expressed willingness to care for HIV-infected patients, knowledge about the mode of HIV transmission and prevention among the respondents were high with existent misconceptions. There were no significant differences in the knowledge about HIV infection and willingness to care for HIV-infected patients among respondents in the lower class and those in upper class.

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.

Radiation protection in dentistry. Recommended safety procedures for the use of dental x-ray equipment. Safety code 30

International Nuclear Information System (INIS)

1994-01-01

The Radiation Protection Bureau has prepared a series of documents on safety codes to set out requirements for the safe use of radiation-emitting equipment. This Safety Code has been prepared to provide specific guidance to the dentist, dental hygienist, dental assistant and other support personnel concerned with safety procedures and equipment performance. Dental radiography is one of the most valuable tools used in modern dental health care. It makes possible the diagnosis of physical conditions that would otherwise be difficult to identify. The use of dental radiological procedures must be carefully managed, because x-radiation has the potential for damaging healthy cells and tissues. Although no known occurrence of cancer or genetic damage has been observed from radiation doses delivered in modern dentistry, and until more evidence is available, one should practice radiation hygiene with the same care as would be dictated if a hazard were known to exist. The aim of radiation protection in dentistry is to obtain the desired clinical information with minimal radiation exposure to patients, dental personnel and the public. 15 tabs

Wall, Thomas P; Brown, L Jackson

2003-05-01

This article describes recent trends in dental visits and private dental insurance in the United States. This study is based on the analyses of data regarding dental visits and private dental insurance among the population 2 years of age or older from the 1989 and 1999 National Health Interview Surveys. Overall, the percentage of the population with a dental visit rose from 57.2 percent in 1989 to 64.1 percent in 1999, while the percentage with private dental insurance fell from 40.5 percent to 35.2 percent. Although a higher percentage of people with private dental insurance reported having a dental visit than did those without private dental insurance in both years, the increase from 1989 to 1999 in the percentage of those with a visit was larger among the uninsured. If this trend persists, a smaller portion of practicing dentist's clientele will be insured. This may affect demand for services, as well as front office operations.

Singhal, Astha; Damiano, Peter; Sabik, Lindsay

2017-04-01

Dental coverage for adult enrollees is an optional benefit under Medicaid. Thirty-one states and the District of Columbia have expanded eligibility for Medicaid under the Affordable Care Act. Millions of low-income adults have gained health care coverage and, in states offering dental benefits, oral health coverage as well. Using data for 2010 and 2014 from the Behavioral Risk Factor Surveillance System, we examined the impact of Medicaid adult dental coverage and eligibility expansions on low-income adults' use of dental care. We found that low-income adults in states that provided dental benefits beyond emergency-only coverage were more likely to have had a dental visit in the past year, compared to low-income adults in states without such benefits. Among states that provided dental benefits and expanded their Medicaid program, regression-based estimates suggest that childless adults had a significant increase (1.8 percentage points) in the likelihood of having had a dental visit, while parents had a significant decline (8.1 percentage points). One possible explanation for the disparity is that after expansion, newly enrolled childless adults might have exhausted the limited dental provider capacity that was available to parents before expansion. Additional policy-level efforts may be needed to expand the dental care delivery system's capacity. Project HOPE—The People-to-People Health Foundation, Inc.

2016-01-01

The aim of this study was to evaluate the factors influencing the satisfaction of dental appearance and attitude toward treatments to improve dental esthetics among patients attending a dental teaching center. A questionnaire was used to collect data of four background variables among 450 patients attended a dental teaching center in the city of Irbid in Jordan. The questionnaire enclosed self-reported questions about the appearance of anterior teeth, received esthetic treatment and desired treatment for improving esthetics. Descriptive, multiple logistic regression and Chi-square tests were used for data analysis (p ≤ 0.05). The 450 participants consisted of (66.2%) male and (33.8%) female. Of these, 69.3% were satisfied with their dental appearance and 58.0% with the color of their teeth. Esthetic restorations were the most received treatment (39.8%) and whitening of teeth was the most desired treatment (55.3%). The patients' satisfaction with dental appearance was influenced by teeth color, crowding and receiving whitening (p < 0.05. r = 0.561, r(2) = 0.315). The most desired esthetic treatments influenced by the satisfaction with dental appearance were esthetic restorations and orthodontics (p < 0.05. r = 0.223, r(2) = 0.05). Significantly more female reported having esthetic restorations and orthodontics (p = 0.008, 0.000) and desired to have orthodontic, crowns or veneers and esthetic restorations (p = 0.000, 0.015, 0.028). Satisfaction with dental appearance was affected by teeth color, feeling teeth are crowded, desire for esthetic restorations and orthodontic treatment. A high percentage of patients were not satisfied with the color of their teeth. Recognizing the factors that affect patients' satisfaction with their present dental appearance and attitude toward treatments to improve dental esthetic can guide clinicians to strategies to improve esthetics.

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

Teleconsultation is defined as consultation, evaluation and management services provided to patients via telecommunication systems with out face-to-face interaction between patient and health-care provider. The increasing clinical relevance of computer assisted navigation technology promoted new perspectives in telemedicine utilizing live sensor data to enhance remote visualization. Any digital content, i.e. digital images from imaging modalities (most frequently Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) as well as navigation data (e.g. intraoperative coordinates of surgical instruments relatively to preplanned pathways and target-points at the patient, implant positions, etc.), can be transferred without any loss of information. This means that remote experts can be involved in surgical interventions or preoperative planning sessions while being supplied with identical information as the 'local' staff. Examples from computer assisted dental implantology are given as well as a case study.

Dental bioaerosol as an occupational hazard in a dentist's workplace.

Science.gov (United States)

Szymańska, Jolanta

2007-01-01

Many-year studies on aerosols as an infection vector, despite their wide range, ignored dental aerosol. All procedures performed with the use of dental unit handpieces cause the formation of aerosol and splatter which are commonly contaminated with bacteria, viruses, fungi, often also with blood. Aerosols are liquid and solid particles, 50 microm or less in diameter, suspended in air. Splatter is usually described as a mixture of air, water and/or solid substances; water droplets in splatter are from 50 microm to several millimetres in diameter and are visible to the naked eye. The most intensive aerosol and splatter emission occurs during the work of an ultrasonic scaler tip and a bur on a high-speed handpiece. Air-water aerosol produced during dental treatment procedures emerges from a patient's mouth and mixes with the surrounding air, thus influencing its composition. Because air contained in this space is the air breathed by both dentist and patient, its composition is extremely important as a potential threat to the dentist's health. According to the author, insufficient awareness of health risk, working habits, and economic factors are the reasons why dentists do not apply the available and recommended methods of protection against the influence of bioaerosol and splatter. Behaviour protecting a dentist and an assistant from the threat resulting from the influence of dental aerosol cannot be limited to isolated actions. The author, on the basis of the literature and own research, characterizes bioaerosol and splatter in a dental surgery and reviews a full range of protective measures against these risk factors.

Purpose: To demonstrate the usefulness of Dental-MRT for imaging of anatomic and pathologic conditions of the mandible and maxilla. Methods: Seven healthy volunteers, 5 patients with pulpitis, 9 patients with dentigerous cysts, 5 patients after tooth transplantation and 12 patients with atrophic mandibles were evaluated. Studies of the jaws using axial T1- and T2-weighted gradient echo and spin echo sequences in 2D and 3D technique have been to performed. The acquired images were reconstructed with a standard dental software package on a workstation as panoramic and cross sectional views of the mandible or maxilla. Results: The entire maxilla and mandibula, teeth, dental pulp and the content of the mandibular canal were well depicted. Patients with inflammatory disease of the pulp chamber demonstrate bone marrow edema in the periapical region. Dentigerous cysts and their relation to the surrounding structures are clearly shown. After contrast media application marked enhancement of the dental pulp can be found. Conclusion: Dental-MRT provides a valuable tool for visualization and detection of dental diseases. (orig.)

All children in Sweden are entitled to regular, free dental care up to 20 years of age. While dental caries generally continues to decline, still there is a pronounced skewness in caries prevalence. Furthermore, the reported increase in dental erosion in young adults is cause for concern. The aim was to study the prevalence of dental caries and dental erosion in a cohort of Swedish 20 year-olds, with special reference to the influence of previous caries experience and lifestyle as well as parental, socioeconomic and psychosocial factors. The study was prospective, longitudinal and cross-sectional in design and based on registration of caries lesions, dental erosion, body adiposity status, saliva sampling, interviews, and questionnaires at 20 years of age. Data were available for the same cohort at 1, 3, 6 and 15 years of age. 499 subjects (74 percent of the original cohort) were included. Five individuals were subsequently excluded, leaving a final sample of 494. 74 percent of the subjects had initial and/or manifest caries lesions and/or restorations. The mean number of DimFS was 5.8 and the mean number of DmFS on occlusal surfaces of molars was 1.1. There was a strong relationship between caries activity at 3 and 6 years of age and approximal caries prevalence in premolars and molars at 20 years of age. Overweight/obese individuals had significantly higher caries prevalence than normal weight individuals. Parental, socioeconomic and psychosocial factors during infancy were related to approximal caries at age 20. Dental erosion was found in 75 percent of the individuals: 18 percent of these had extensive erosion. There was a significant association between caries and dental erosion. A relationship was found between dental erosion and lifestyle factors and overweight/obesity. There is a strong relationship between caries prevalence at age 20 and caries experience in early childhood. Young adults show a high prevalence of dental erosion, but the severity is

There is a great need for leaders in the dental profession. As technological advances make our world smaller and our lives faster and more complex, we as a profession face challenges and opportunities that are evolving. Many of the changes in the scope and mode of practice will require new and different approaches. Meeting these challenges will require changes in how we as dental professionals do business; interact with our patients, other stakeholders, and health care providers; and educate our future colleagues. The purposeful incorporation of leadership education into dental and dental hygiene curricula represents an important departure from existing paradigms-but will help prepare our students to address these challenges. This article provides an overview of the development of a Scholars Program in Dental Leadership (SPDL) at the University of Michigan School of Dentistry. Our aim for the program is to create a learning environment that fosters leadership development, so that students are prepared and motivated to assume leadership positions in the profession and their communities.

Dental caries's diagnosis is a major dentistry problem from the clinic point of view. The laser beam on the region of 655 nm induces the fluorescence of the compounds present in the hard tissue, quantifying differences between sound and carious enamel and dentine. Diagnodent (Kavo, Germany), showed to be effective regarding dental caries's diagnosis in the present research sampling. The Er:YAG laser (Kavo Key Laser 2, Germany) performed efficient cavity preparations in caries lesions of I and V class type, using up energies that ranged from 300 mJ to 350 mJ with 4 Hz repetition rate for the enamel; and from 250 mJ to 300 mJ with 4 Hz repetition rate for the dentine, and with 80 mJ with 6 Hz of repetition rate for laser conditioning. In the Er:YAG laser preparations no patient was anesthetized even when there were deeper cavities, and the maximum degree of pain ( which ranged from 0 to 10) was 4. In the control group with conventional high-speed drill two patients were anesthetized and the maximum degree of pain was 7. Restorations performed by conventional method of composite were equally satisfying both in caries groups of I and V class type and in the control group. The laser application in the operative dentistry office as a new method of diagnosis and dental preparations should be a good alternative to the use of the conventional dental drill. Nevertheless, dentistry practice has a lot to improve from technology progress, as well as new researches on laser dentistry are necessary in a long term. New types of lasers will come about and will increasingly improve the dental practice assistance and procedures quality. (author)

2012-07-01

The purpose of this study was to determine the methods dental practitioners in the United Arab Emirates (UAE) use to communicate cast removable dental prosthesis (RDP) design to dental laboratories; identify common practices taken by dentists/dental technicians prior to fabrication of RDP framework; and seek out dental technicians' attitudes toward their role in RDP design decisions. All dental laboratories (n = 28) listed in a local telephone directory were invited to complete a questionnaire through a face-to-face interview. They were also requested to examine RDP cases fabricated in the past 2 months and identify steps taken by dentists/dental technicians prior to fabrication of the framework. Descriptive statistics were used to report frequencies and percentages. Twenty-one (75%) dental laboratories agreed to participate, out of which 19 had the facilities to fabricate chrome-cobalt RDPs. Cast RDPs comprised approximately 4.04% (±2.67) of services provided. A reported 84.2% of dentists frequently communicate through generic lab script, with 89.5% rarely/never giving details regarding RDP design. While 52.6% of labs agree/strongly agree that it is the dentist's responsibility to decide the final RDP design, 94.7% agree/strongly agree that dentists should depend on dental technicians for design-making decisions. A total of 19 RDP cases were reviewed. All 19 were surveyed and designed by dental technicians but received dentist approval of design prior to fabrication. Thirteen (68.4%) had rest-seat preparations done by dentists after approval, and new impressions sent to the lab. No other tooth modifications were noted. The responsibility of RDP design appeared to be largely delegated to dental technicians. Importance of tooth modifications seemed to be undervalued and not completed prior to framework fabrication. © 2012 by the American College of Prosthodontists.

Full Text Available Objective: Proper positioning of the child patient, can not only have positive ramifications for the operator′s posture, comfort, and career longevity - it can also lead to better treatment and increased productivity. The aim of the survey questionnaire was to assess the utilization, need, and attitude concerning dental chairs among pediatric dentist while working on and managing the child patient. Study Design: The questions were structured using adobe forms central online software, regarding the user-friendliness of pediatric dental chair vs. traditional adult dental chair available in the market. Results: Our result shows that out of 337 respondents, 79% worked on pediatric dental chair, whereas 21% had no experience of it. Of these 79% pediatric dentist, 48% preferred pediatric dental chair. But pediatric dental problem still has certain disadvantages like higher cost, leg space problem, lower availability, etc. Conclusion: During the research it was found that ergonomics and usability issues were the main problems. Thus, pediatric dental chair is not so popular in the current scenario. This study allowed for general ideas for the improvement of dental chairs and thus improved dental chair would fill the gap in the current scenario.

Organisational aspects of dental practices: do dental students think like patients or like general dental practitioners?

Sonneveld, R E; Brands, W G; Bronkhorst, E M; Welie, J V M; Truin, G J

2013-02-01

In view of transparency in health care, the widespread desire for more patient-centred care, and in an attempt to facilitate educational programmes that effectively respond to these changes, two research questions are formulated: (i) How do dental students rate the importance of various organisational aspects of dental practices compared with dental patients and general dental practitioners (GDPs), and what prescripts, defined as specific operational responsibilities of GDPs in these matters, do dental students propose? and (ii) In doing so, do students resemble patients or GDPs? In two survey studies, dental students (n = 198), patients (n = 3127) and GDPs (n = 303) were asked to rate by questionnaire the importance of 41 organisational aspects of a general dental practice and proposed specific operational responsibilities ('prescripts'). Seven of 41 aspects were rated as important by the majority of the students. Although in a different rank order, three aspects were predominantly selected by all three groups: continuing education, accessibility by telephone and Dutch-speaking GDP. For most aspects, significant differences were found between the prescripts proposed by students and those proposed by patients, and few differences were found between students and GDPs. The findings do not permit the general conclusion that the views of dental students resemble those of patients or GPDs. Looking at the overall rank order, the three respondent groups showed a great resemblance although significant differences were found for specific aspects. With regard to the proposed prescripts, students showed realistic views and the majority wants to participate in continuing education and work with protocols and guidelines. In this, they tend to resemble GDPs more than they resemble patients. © 2012 John Wiley & Sons A/S.

Dental education in Peru.

2008-09-01

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

U.S. Dental School Deans’ Perceptions of the Rising Cost of Dental Education and Borrowing Pressures on Dental Students: Report of Survey Results.

2015-06-01

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

Barriers and Drawbacks of the Assessment of Dental Fear, Dental Anxiety and Dental Phobia in Children: A Critical Literature Review.

Science.gov (United States)

Asl, Aminabadi Naser; Shokravi, Marzieh; Jamali, Zahra; Shirazi, Sajjad

Dental anxiety, fear and phobia have different etiology, response patterns, time courses, and intensities that justify a clear distinction between these constructs. Differentiation of dental anxiety, fear or phobia in practice is a critical prerequisite for developing and implementing effective treatment for children. The aim of this study was to investigate whether current researches in the pediatric dentistry appropriately discriminate the central construct of dental anxiety, fear and phobia. We also highlighted the specific methodological issues in the assessment of these issues in pediatric dentistry. A systematic search was conducted in Pubmed/medline and Scopus for articles which assessed dental anxiety, fear or phobia in children. 104 research papers were included in the review that had made a distinction between dental anxiety, fear and phobia and had not used them interchangeably. Only five studies used different clinical measures or cut-offs to discriminate between dental anxiety, fear and phobia. The dental literature appears unable to capture and also measure the multi-sided construct of dental anxiety, fear and phobia and, therefore, there was a tendency to use them interchangeably.

Home patients have few chances for going out, so communication with their family means a lot. Talking and eating are particular pleasures. Therefore, oral and dental health and oral and dental support are very important for home patients. A dental hygienist from our clinic visits and offers oral and dental health (oral care) and oral and dental support (oral rehabilitation) to home patients as part of a care plan with home care nurses. Moreover, as general conditions are closely related with oral function, maintaining oral and dental health and regular oral and dental support are very important in order to improve the quality of life (QOL) of home patients.

PENN PASS: a program for graduates of foreign dental schools.

1994-01-01

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.

Purpose: Many states are exploring alternative provider models and examining the role of the dental hygienist to address access to care challenges as the United States continues to face increasing demands for oral healthcare services. The purpose of this study was to assess dental hygienists' opinions in the state of Oregon regarding the current limitations of dental hygienists' scope of practice, perceived need for a mid-level provider in Oregon, and personal interest in becoming a mid-level provider. Methods: In December 2013 a survey was mailed to a sample of 1,231 dental hygienists registered in Oregon representing 30% of the licentiates. All licentiates holding expanded practice permits (EPP) were included in the sample (n=351). The following categories were included in the 32-question survey: scope of practice, mid-level provider, current practice, and demographics. Results: A total of 440 surveys were returned for a response rate of 36%. Of the EPP holders, 51% responded to the survey. Over half of respondents (59%) believe that a mid-level provider is needed in the state. Respondents holding membership in the American Dental Hygienists' Association, as well as EPP holders, were significantly more likely to respond that a mid-level dental provider was needed in the state (plevel provider was introduced in Oregon, the new provider should be a registered dental hygienist model. Forty-three percent (n=186) of respondents were interested in becoming mid-level providers and 47% (n=203) of respondents believed that the minimum education for a mid-level provider should be a bachelor's degree. The majority, 74% (n=137), of those interested in becoming a mid-level provider indicated a preference in completing their education through online teaching combined with a clinical internship. Conclusion: There is strong support from dental hygienists in Oregon that a need exists for a mid-level dental provider and that this provider model should be dental hygiene based

Policy has recently changed on provision of dental general anaesthetic services in England. The aim of this study was to investigate general dental practitioners' views about dental general anaesthetics, the reduction in its availability and the impact on care of children with toothache. Qualitative study using semi-structured interviews and clinical case scenarios. General dental practitioners providing NHS services in the North West of England. 93 general dental practitioners were interviewed and 91 answered a clinical case scenario about the care they would provide for a 7-year-old child with multiple decayed teeth presenting with toothache. Scenario responses showed variation; 8% would immediately refer for general anaesthesia, 25% would initially prescribe antibiotics, but the majority would attempt to either restore or extract the tooth causing pain. Interview responses also demonstrated variation in care, however most dentists agree general anaesthesia has a role for nervous children but only refer as a last resort. The responses indicated an increase in inequalities, and that access to services did not match population needs, leaving some children waiting in pain. Most general dental practitioners support moving dental general anaesthesia into hospitals but some believe that it has widened health inequalities and there is also a problem associated with variation in treatment provision. Additional general anaesthetic services in some areas with high levels of tooth decay are needed and evidence based guidelines about caring for children with toothache are required.

Dental x-rays and the risk of thyroid cancer: A case-control study

International Nuclear Information System (INIS)

Memon, Anjum; Godward, Sara; Williams, Dillwyn; Siddique, Iqbal; Al-Saleh, Khalid

2010-01-01

The thyroid gland is highly susceptible to radiation carcinogenesis and exposure to high-dose ionising radiation is the only established cause of thyroid cancer. Dental radiography, a common source of low-dose diagnostic radiation exposure in the general population, is often overlooked as a radiation hazard to the gland and may be associated with the risk of thyroid cancer. An increased risk of thyroid cancer has been reported in dentists, dental assistants, and x-ray workers; and exposure to dental x-rays has been associated with an increased risk of meningiomas and salivary tumours. Methods. To examine whether exposure to dental x-rays was associated with the risk of thyroid cancer, we conducted a population-based case-control interview study among 313 patients with thyroid cancer and a similar number of individually matched (year of birth ± three years, gender, nationality, district of residence) control subjects in Kuwait. Results. Conditional logistic regression analysis, adjusted for other upper-body x-rays, showed that exposure to dental x-rays was significantly associated with an increased risk of thyroid cancer (odds ratio = 2.1, 95% confidence interval: 1.4, 3.1) (p=0.001) with a dose-response pattern (p for trend <0.0001). The association did not vary appreciably by age, gender, nationality, level of education, or parity. Discussion. These findings, based on self-report by cases/controls, provide some support to the hypothesis that exposure to dental x-rays, particularly multiple exposures, may be associated with an increased risk of thyroid cancer; and warrant further study in settings where historical dental x-ray records may be available.

The thyroid gland is highly susceptible to radiation carcinogenesis and exposure to high-dose ionising radiation is the only established cause of thyroid cancer. Dental radiography, a common source of low-dose diagnostic radiation exposure in the general population, is often overlooked as a radiation hazard to the gland and may be associated with the risk of thyroid cancer. An increased risk of thyroid cancer has been reported in dentists, dental assistants, and x-ray workers; and exposure to dental x-rays has been associated with an increased risk of meningiomas and salivary tumours. Methods. To examine whether exposure to dental x-rays was associated with the risk of thyroid cancer, we conducted a population-based case-control interview study among 313 patients with thyroid cancer and a similar number of individually matched (year of birth +- three years, gender, nationality, district of residence) control subjects in Kuwait. Results. Conditional logistic regression analysis, adjusted for other upper-body x-rays, showed that exposure to dental x-rays was significantly associated with an increased risk of thyroid cancer (odds ratio = 2.1, 95% confidence interval: 1.4, 3.1) (p=0.001) with a dose-response pattern (p for trend <0.0001). The association did not vary appreciably by age, gender, nationality, level of education, or parity. Discussion.

To examine prenatal dental care needs, utilization and oral health counseling among Maryland women who delivered a live infant during 2001-2003 and identify the factors associated with having a dental visit and having an unmet dental need during pregnancy. Pregnancy Risk Assessment Monitoring System is an ongoing population based surveillance system that collects information of women's attitudes and experiences before, during, and shortly after pregnancy. Logistic regression was used to model dental visits and unmet dental need using predictor variables for Maryland 2001-2003 births. Less than half of all women reported having a dental visit and receiving oral health advice during pregnancy. Twenty-five percent of women reported a need for dental care, of which 33 % did not receive dental care despite their perceived need. Multivariate modeling revealed that racial minorities, women who were not married and those with annual income dental visit. Women who were not married, had low annual income, were older than 40 years of age, had an unintended pregnancy and received prenatal care later than desired were most likely to have an unmet dental need during pregnancy. Despite reported needs and existing recommendations to include oral health as a component of prenatal care, less than half of pregnant women have a dental visit during their pregnancy. One-third of women with a dental problem did not have a dental visit highlighting the unmet need for dental care during pregnancy.

To examine the relationship between self-reported parental rearing style, parent's assessment of their child's dental anxiety and the dental history of children. Parents of primary school children were asked to complete questionnaires about their parenting style, using four different questionnaires. Parents also completed the Child Fear Survey Schedule Dental Subscale (CFSS-DS) on behalf of their child and a questionnaire about the dental history of their child. 454 interview forms were available for analysis. Minor associations were found between dental anxiety and parenting style. Anxious parents were more permissive and less restrictive in their parenting style. Parents of children who did not visit their dentist for regular check-ups reported more laxness and less restrictiveness. Children who had a cavity at the time of investigation, children who had suffered from toothache in the past and children who did not have a nice and friendly dentist reported more dental anxiety. No clear associations between parenting style and dental anxiety were found. Known causes of dental anxiety were confirmed.

Scarbecz, Mark; Ross, Judith A

2002-08-01

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

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.

The purposes of this research were to investigate factors influencing patients' satisfaction with their present dental esthetic, received previous dental treatments on anterior teeth and basic treatments that they wanted to undergo to improve their dental appearance. A total of 1014 patients who attended a dental school in a major city in Turkey participated in the study. The participants were surveyed with a questionnaire containing questions about gender, age, education level, self-reported tooth appearance, received previous dental treatments on anterior teeth and desired basic esthetic dental treatments. Statistical analysis of the verifying data was made with descriptive statistics, chi2 test and multiple logistic regression analyses. According to the analyses of the verifying data, 55.1% of the patients were dissatisfied with the color of their teeth, 42.7% with dental appearance, 29.9% with crowding of anterior teeth, 23.3% were hiding teeth while smiling, 16.1% had non-esthetic restorations and 11.9% thought that their anterior teeth were protruding. Esthetic restoration was found to be the most-performed treatment recently (29.0%) and whitening of teeth was the most-desired dental treatment (49.0%). Gender, age and education level had an effect on satisfaction and received previous and desired dental treatments for improvement of esthetics. Many of the Turkish patients surveyed in the study were dissatisfied and desired the improvement of dental esthetics. Therefore, dentists should consider this as an important dimension in their practice.

A dental chart is very useful as a standard source of evidence in the personal identification of bodies. However, the kind of dental chart available will often vary as a number of types of odontogram have been developed where the visual representation of dental conditions has relied on hand-drawn representation. We propose the Digital Dental Chart (DDC) as a new style of dental chart, especially for open investigations aimed at establishing the identity of unknown bodies. Each DDC is constructed using actual oral digital images and dental data, and is easy to upload onto an Internet website. The DDC is a more useful forensic resource than the standard types of dental chart in current use as it has several advantages, among which are its ability to carry a large volume of information and reproduce dental conditions clearly and in detail on a cost-effective basis.

Becoming a dental professional requires one to apply ethical decision making skills and demonstrate high standards of professionalism in practice, including the way professionals present themselves to the public. With social media as an evergrowing part of personal and professional communications, this study aimed to determine the accessibility, amount, and type of unprofessional content on Facebook profiles of dental hygiene and dental students in a college of dentistry. The authors evaluated the online profiles of all 499 dental and dental hygiene students at The Ohio State University using objective measures that included existence of a profile, current privacy settings, and access to personally identifiable information. A sample of profiles were evaluated for unprofessional content including photos, comments, and wall posts. The majority of these students were found to use Facebook, with 61 percent having Facebook profiles. Dental hygiene students were more likely to have a Facebook profile than were dental students: 72.6 percent and 59.1 percent, respectively (p=0.027). The majority of the students' profiles had some form of privacy setting enabled, with only 4 percent being entirely open to the public. Fewer than 2 percent of the students allowed non-friends access to personal information. Based on in-depth analysis of the profiles, fourteen (5.8 percent) instances of unprofessionalism were recorded; the most common unprofessional content involved substance abuse. This study found that these dental and dental hygiene students frequently possessed an identifiable Facebook account and nearly half had some kind of personal information on their profile that could potentially be shared with the public. In some instances, the students gave patients, faculty, and potential employers access to content that is not reflective of a dental professional. Academic institutions should consider implementing policies that bring awareness to and address the use of social media

Full Text Available The aim of the present study was to evaluate the association between childhood dental experiences and dental fear in adulthood among dentistry, psychology and mathematics undergraduate students. A cross-sectional study of 1,256 students from the city of Belo Horizonte, Brazil, was performed. Students responded to the Brazilian version of the Dental Fear Survey (DFS and a questionnaire regarding previous dental experiences. Both the DFS and the questionnaire were self-administered. Association was tested using descriptive, bivariate and multivariate linear regression analysis, with a 5% significance level. Dentistry undergraduates reported lower scores than psychology (p < 0.001 and mathematics undergraduates (p < 0.05 for all three dimensions of the DFS. Negative dental experiences in childhood was associated with dimensions of Avoidance (B = 2.70, p < 0.001, Physiological arousal (B = 1.42, p < 0.001 and Fears of specific stimuli/situations (B = 3.44, p < 0.001. The reason for first visit to dentist was associated with dimensions of Physiological arousal (B = 0.76, p < 0.01 and Fears of specific stimuli/situations (B = 1.29, p < 0.01. Dentists should be encouraged to evaluate the dental fear of their patients before treatment. The DFS has been found to be an effective instrument for this purpose.

Biocompatibility of dental alloys

Energy Technology Data Exchange (ETDEWEB)

Braemer, W. [Heraeus Kulzer GmbH and Co. KG, Hanau (Germany)

2001-10-01

Modern dental alloys have been used for 50 years to produce prosthetic dental restorations. Generally, the crowns and frames of a prosthesis are prepared in dental alloys, and then veneered by feldspar ceramics or composites. In use, the alloys are exposed to the corrosive influence of saliva and bacteria. Metallic dental materials can be classified as precious and non-precious alloys. Precious alloys consist of gold, platinum, and small amounts of non-precious components such as copper, tin, or zinc. The non-precious alloys are based on either nickel or cobalt, alloyed with chrome, molybdenum, manganese, etc. Titanium is used as Grade 2 quality for dental purposes. As well as the dental casting alloys, high purity electroplated gold (99.8 wt.-%) is used in dental technology. This review discusses the corrosion behavior of metallic dental materials with saliva in ''in vitro'' tests and the influence of alloy components on bacteria (Lactobacillus casei and Streptococcus mutans). The test results show that alloys with high gold content, cobalt-based alloys, titanium, and electroplated gold are suitable for use as dental materials. (orig.)

Three-dimensional volume data set is useful for diagnosis in dental treatments. However, to obtain three-dimensional images of a dental arch in general dental clinics is difficult. In this paper, we propose a method to reconstruct pseudo three-dimensional dental images from a dental panoramic radiograph and a tooth surface shape which can be obtained from three dimensional shape measurement of a dental impression. The proposed method finds an appropriate curved surface on which the dental panoramic radiograph is mapped by comparing a virtual panoramic image made from a tooth surface shape to a real panoramic radiograph. The developed pseudo three-dimensional dental images give clear impression of patient's dental condition. (author)

History of dental hygiene research.

Science.gov (United States)

Bowen, Denise M

2013-01-01

Dental hygiene is defined as the science and practice of the recognition, treatment and prevention of oral diseases. The history of dental hygiene research is considered in the context of the development of the discipline and an emerging infrastructure. Research-related events supporting the growth and maturation of the profession are considered from the early years to the most recent. The benefits of preventive oral health services provided by dental hygienists have been supported by research, and the practice of dental hygiene has expanded as a result of research findings since its inception 100 years ago. Dental hygienists' engagement in research, however, did not begin until the 1960s as research associates or administrators, primarily with dental researchers as primary investigators. The Journal of Dental Hygiene (JDH) has provided information for dental hygiene practice since 1927, and has been the primary venue for dissemination of dental hygiene research since 1945. Graduate education in dental hygiene at the master's degree level and the work of early dental hygiene researchers led to the first conference on dental hygiene research in 1982. Over 30 years later, dental hygiene has established a meta-paradigm and defined conceptual models, built an initial infrastructure to support research endeavors and contributed much to the development of dental hygiene as a unique discipline. A doctoral degree in the discipline, continued theory-based research, initiatives to foster collaborations between dental hygiene and other researchers and enhanced capabilities to attract funding to support large scale studies are goals that must be attained through the efforts of future researchers to address the needs for additional development in the discipline of dental hygiene. Dental hygiene research supports the growing discipline and its value to society.

To describe the pattern of dental services provided to 64-65-year-old Danes who are regular users of dental care over a 5-year period, to analyse whether this pattern is associated with socio-demographic and/or socioeconomic factors, and if different uses of dental services are related to dental status and caries experience. Finally, to discuss the future planning of dental services aimed at the increasing population of elderly citizens. [Correction made on 21 March 2014, after first online publication: The sentence 'Data on elderly's dental service are scarce, although increased use is seen and more teeth are present in this age group.' was removed.] A cross-sectional study of all aged 64-65 (n = 37 234) who received a dental examination in 2009 was conducted. Clinical data comprised dental services received under the National Health Insurance reimbursement scheme, dental status and DMFT. Geographical, socio-demographic and socioeconomic data derived from public registers. Almost all received restorations, while periodontal treatment was received by dental services was dominated by periodontal services. Periodontal services were most prevalent in the capital and the most affluent areas. Relatively more extractions were related to low income and persons in least affluent areas. Total number of services was highest among women, persons with ≥20 teeth, persons living in the capital, and where the ratio user per dentist was low. For future planning of dental care for elderly, dental status, geographical and social area-based factors and to some degree gender, income, and education must be taken into consideration as all these factors seem to influence the future demand for dental services. © 2014 John Wiley & Sons A/S and The Gerodontology Association.

Meiller, T F; Kelley, J I; Baqui, A A; DePaola, L G

2001-01-01

Dental unit waterline biofilm has been recognized as a potential point of contamination and a risk to patients with any level of immunocompromise. Biofilm in dental unit waterlines, once established, has proven formidable to efforts in disinfection/disruption. This project compared standardized evaluation techniques by assessing the efficacy of a variety of agents that have been reported or suggested as useful in surface disinfection and/or antiseptic protocols. The zones of inhibition, minimum inhibitory/bactericidal concentrations and use-dilution with stainless steel carrier replicates tests assessed the disinfection of planktonic organisms using standardized microbial testing procedures. The disruption and/or disinfection of planktonic and biofilm organisms within naturally occurring dental unit waterlines were evaluated by culture and scanning electron microscopy. The six commercially available antimicrobial agents used to assess the techniques were bleach (sodium hypochlorite), Cavicide, glutaraldehyde, Listerine Antiseptic, Peridex and Sterilex Ultra. Comparisons between the results for each technique evaluated were determined for each product. All six agents demonstrated antimicrobial efficacy at the working concentrations designated by the manufacturers. Biofilm matrix elimination evaluated by scanning electron microscopy found virtually 0% elimination by glutaraldehyde to an estimated 90% elimination by Sterilex Ultra and bleach after one treatment. Treatment with Cavicide, Listerine Antiseptic and Peridex resulted in negligible elimination of the biofilm matrix. For comparability, the use of standardized testing techniques to evaluate a disinfection agent's efficacy against dental unit waterline contamination is essential. This project demonstrates a model system for evaluating disinfection agents potentially useful in the management of dental unit waterline biofilm, and should assist in educating the dental clinician in the appraisal of existing and

India faces an acute shortage of health personnel. Together with inequalities in distribution of health workers, dental health workers also become a part contributing to it impeding the progress towards achievement of the Millennium Development Goals. To assess dental health-workforce distribution, identify inequalities in dental health-workers provision and report the impact of this mal distribution in India. Situational analysis done by using the primary data from the records of Dental Council of India. In India, 0.088% of dental health worker per 1000 population exists. Inequalities in the distribution of dentists exist in India. Certain states are experiencing an acute shortage of dental health personnel whereas certain cities are over fledged with dentists like Karnataka, Maharastra, Tamilnadu being states with high concentration & Jharkhand, Rajasthan, Uttaranchal being the least. Although the production of health workers has expanded greatly in recent years by increase in number of dental colleges the problems of imbalances in their distribution persist. In the race of increasing dentist population ratio in total, inequitable distribution of appropriately trained, motivated and supported dentists gives a mere feel of saturation in jobs making youngsters to not to choose dentistry as a career giving an alarm.

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

There is a general consensus regarding the lack of awareness regarding the emergency management of traumatic dental injuries amongst laypersons and dental professionals. This article aims to provide an overview of the apps available for traumatic dental injuries using smartphones. These apps may serve as a gateway for raising awareness of traumatic dental injuries. Three smartphone devices were used to access their respective app stores (Nokia Lumia 635 with Windows Phone OS 8.1; iPhone 5 with iOS 8.1; Samsung Galaxy Ace II with Android OS v2.3.6 Gingerbread). Nine phrases were searched: broken tooth/teeth; chipped tooth/teeth; dental emergency; dental injury; dental trauma; fractured tooth/teeth; knocked-out tooth/teeth; tooth/teeth injury; and tooth/teeth trauma. Seven apps for the Android and one app for the Apple operating system were relevant. The only Apple iOS app retrieved (Dental Trauma) was also found for the Android OS (Dental Trauma First Aid) and had the endorsement of the International Association of Dental Traumatology. AcciDent was the only app dedicated to traumatic dental injuries targeted solely towards dental professionals. Five other apps (Chipped Tooth Solution, Dental Crown Repair, Fixing Cracked Tooth, Repairing the Front Tooth and Solution to Broken Tooth) appeared to come from the same source (KBES). No traumatic dental injury apps were found for the Windows Phone OS. There are apps available for both patients and dentists that range in quality and on the whole lack real-life photographs. Future apps should continue to provide good quality, evidence-based and validated material. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Entrepreneurship in continuing dental education: a dental school perspective.

Liberto, Vincent N

2005-01-01

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

This study investigates student and stakeholder perceptions of the role of the dental hygienist in Nepal. The impact of these perceptions on the professionalization of dental hygienists is described whilst exploring the consequences for oral health workforce planning. Dentistry and dental hygiene students from one dental college in Nepal were asked to complete an anonymous questionnaire; 171 students returned the questionnaire containing a mix of forced response and open-ended items. Quantitative data were analysed using SPSS ® 22. These data were complemented with qualitative information from survey open questions and from semi-structured interviews with key informants from several relevant organizations. Qualitative data were manually analysed and coded. Data were triangulated to contextualize quantitative data. A high level of positive regard for the role of the dental hygienist in Nepal was evident amongst dentistry and dental hygiene students in this college. Both groups believe that the dental hygienist can play a major role in raising oral health awareness in Nepal. The scope of practice of the dental hygienist was unclear with issues surrounding the scope of practice and reports of illegal practice by dental hygienists. Significant differences (P dental hygiene and dentistry students in relation to their opinion regarding independent practice and the need of supervision by a dentist. Supervision of the dental hygienist by dentists and issues surrounding the scope of practice are polarizing the relationship between dentists, dental hygienists and the relevant professional organizations. This could hinder cooperation between these oral health professionals and might lead to underutilization of the dental hygienist. To improve the understanding about the roles of each oral health professional, establishing functional relationships and intraprofessional education involving dentistry and dental hygiene students needs to be introduced. This will benefit the

This study aimed to better understand low-income parents' child dental care decisions through a life course approach that captured parents' experiences within the social context of poverty. We conducted 43 qualitative life history interviews with 10 parents, who were long-term social assistance recipients living in Montreal, Canada. Thematic analysis involved interview debriefing, transcript coding, theme identification and data interpretation. Our interviews identified two emergent themes: lay diagnosis and parental oral health management. Parents described a process of 'lay diagnosis' that consisted of examining their children's teeth and interpreting their children's oral signs and symptoms based on their observations. These lay diagnoses were also shaped by their own dental crises, care experiences and oral health knowledge gained across a life course of poverty and dental disadvantage. Parents' management strategies included monitoring and managing their children's oral health themselves or by seeking professional recourse. Parents' management strategies were influenced both by their lay diagnoses and their perceived ability to manage their children's oral health. Parents felt responsible for their children's dental care, empowered to manage their oral health and sometimes forgo dental visits for their children because of their own self-management life history. This original approach revealed insights that help to understand why low-income parents may underutilize free dental services. Further research should consider how dental programs can nurture parental empowerment and capitalize on parents' perceived ability to diagnose and manage their children's oral health.

Capelozza, Ana Lucia Alvares.

1988-01-01

This study was carried out in order to evaluate the behaviour of 145 dentists, in their offices, as far as radiation protection in concerned. Every dental office was visited and the dentist filled out a form with questions regarding to radiation protection of patient, professional and dental assistant. The same visit exposure and processing conditions of intraoral films were checked and a no-screen film was exposed for late measurement of the diameter of x-ray bean. After data analysis it seems fair to conclude that exposure and processing conditions could be improved if the correct exposure and development times according to those suggested by their manufactures were employed. Another reasonable conclusion that could be drawn from the obtained data: the number of dental radiographs taken is small and so the probability of biological damage is not significant at the level of present knowledge.

2014-01-01

Full Text Available Background and Objectives: Preventive approach in dental practice has been cited as a reason for the decline in oral diseases and as a predominant part of the service-mix of dental practices in the future. Dental faculty′s knowledge and attitude toward prevention are important, since they have exceptionally important direct and indirect roles in shaping student′s preventive orientation and also potentially influencing their patient′s ability to take care of their teeth. Thus, this study was conducted to assess knowledge and attitudes toward preventive dental care among dental faculties and their relation to demographic and professional characteristics. Materials and Methods: A cross-sectional study was conducted among dental faculties in Bangalore city. Of 17 dental colleges, 4 were selected by simple random sampling. A total of 218 dental faculties was individually asked to complete a pretested questionnaire. The questionnaire requested information on dental faculty′s demographic and professional characteristics and their knowledge and attitudes toward preventive dental care. Descriptive, Chi-square tests, and ANOVA were used to analyze the data. Results: The highest knowledge was seen among dental faculties regarding prevention of malocclusion (3.51 ± 1.02 followed by oral cancer (2.95 ± 1.09 and periodontal diseases (2.86 ± 1.02. The least knowledge was seen for the prevention of caries (2.63 ± 1.35. The most positive attitudes regarding preventive dentistry was characterized as being essential (6.34 ± 1.05, useful (6.32 ± 1.07 and valuable (6.27 ± 1.00. Statistically significant differences were found in relation to knowledge and attitudes for all demographic and professional characteristics except for gender and Department of Teaching. Conclusion: Dental faculty seems to have differing levels of knowledge regarding oral diseases with positive attitudes seen regarding preventive dentistry. Continuing education activities and

Regenerative medicine in dental and oral tissues: Dental pulp mesenchymal stem cell

Directory of Open Access Journals (Sweden)

Janti Sudiono

2017-08-01

Full Text Available Background. Regenerative medicine is a new therapeutic modality using cell, stem cell and tissue engineering technologies. Purpose. To describe the regenerative capacity of dental pulp mesenchymal stem cell. Review. In dentistry, stem cell and tissue engineering technologies develop incredibly and attract great interest, due to the capacity to facilitate innovation in dental material and regeneration of dental and oral tissues. Mesenchymal stem cells derived from dental pulp, periodontal ligament and dental follicle, can be isolated, cultured and differentiated into various cells, so that can be useful for regeneration of dental, nerves, periodontal and bone tissues. Tissue engineering is a technology in reconstructive biology, which utilizes mechanical, cellular, or biological mediators to facilitate regeneration or reconstruction of a particular tissue. The multipotency, high proliferation rates and accessibility, make dental pulp as an attractive source of mesenchymal stem cells for tissue regeneration. Revitalized dental pulp and continued root development is the focus of regenerative endodontic while biological techniques that can restore lost alveolar bone, periodontal ligament, and root cementum is the focus of regenerative periodontic. Conclucion. Dentin-derived morphogens such as BMP are known to be involved in the regulation of odontogenesis. The multipotency and angiogenic capacity of DPSCs as the regenerative capacity of human dentin / pulp complex indicated that dental pulp may contain progenitors that are responsible for dentin repair. The human periodontal ligament is a viable alternative source for possible primitive precursors to be used in stem cell therapy.

Dental anxiety and personality: investigating the relationship between dental anxiety and self-consciousness.

Economou, George C

2003-09-01

This study investigated whether personality plays a role in a condition called dental anxiety. Specifically, the study examined the relationship between dental anxiety (the negative response to the stress elicited from a dental interaction) and self-consciousness (the tendency to evaluate aspects of oneself that are subject to private and public display). The purpose of this study was to identify the characteristics possessed by dentally anxious individuals who face potential health risks because of their avoidance. Sixty York University undergraduate students were recruited by convenience sampling to participate. These subjects completed Corah's Dental Anxiety Scale and the Self-Consciousness Scale. The Self-Consciousness Scale consists of three subscales, including private self-consciousness, public self-consciousness, and social anxiety. Results indicated an 0.54 significant correlation between dental anxiety and self-consciousness. The public self-consciousness and social anxiety subscales correlated the most with dental anxiety. Furthermore, the data did not indicate a significant moderating relationship for gender between the two aforementioned variables. These results contribute to the establishment of personality characteristics as one of the dimensions determining dental anxiety.

Brown, Nathan L; Jephcote, Victoria E L

2017-03-01

Fourteen dentists at different practices in the UK assessed the dental charts of 1128 patients who were new to the dentist but not new to the practice; 44% of the dental charts were found to be inaccurate. Inaccuracy of the individual practice-based charts ranged between 16% for the best performing practices to 83% for the worst: 5% of dental charts had too many teeth charted and 5% had too few teeth charted; 13% of charts had missed amalgam restorations and 18% had missed tooth-coloured restorations; 5% of charts had amalgam restorations recorded but with the surfaces incorrect (eg an MO restoration charted but a DO restoration actually present); 9% of charts had tooth-coloured restoration surfaces incorrectly recorded. For 7.5% of charts, amalgams were charted but not actually present. Other inaccuracies were also noted. The authors reinforce the requirements of the GDC, the advice of defence organizations, and the forensic importance of accurate dental charts. Clinical relevance: Dental charting forms part of the patient’s dental records, and the GDC requires dentists to maintain complete and accurate dental records.

Purpose: To establish a new method for dental imaging using magnetic resonance tomography named Dental-MRT and to demonstrate its usefulness in diagnosing dentogen pathologies of the mandible and maxilla. Methods: Seven healthy volunteers, three patients with pulpitis, two patients with dentigerous cysts, two patients after tooth transplantation, and three patients with atrophic mandibles have been evaluated. Optimized axial T{sub 1}- and T{sub 2}-weighted gradient echo and spin echo sequences in 2D and 3D technique have been established to perform studies of the jaws. The acquired images were reconstructed with a standard dental software package on a workstation as panorama and cross-sectional views of the mandible or maxilla. Results: The entire maxillo-mandibular bone, teeth, dental pulp, and the content of the mandibular canal were well depicted. Patients with pulpitis demonstrate bone marrow edema in the periapical region. Dentigerous cysts and their relation to the surrounding structures are clearly shown. After contrast media administration marked enhancement of the dental pulp can be demonstrated. Conclusion: Dental-MRT promises to provide a new tool for visualization and detection of dental diseases. (orig.)

To discover the quality of written instructions from dentists to dental technicians and the nature of non-compliant prescriptions. An audit of laboratory prescription compliance was conducted within an NHS Trust Dental Teaching Hospital to determine the level of communication between dentists and dental technicians. One hundred and fifty prescriptions were audited from dental undergraduates and qualified dentists throughout the different departments. A total of two-thirds of prescriptions were considered non-compliant and failed to meet relevant ethical and legal guidelines. This problem was seen throughout all departments and at all professional levels. A breakdown in communication between dentists and technicians through the use of prescriptions is evident even within a close working environment.

The aim of this randomized controlled trial was to analyze inexperienced dental students' perceptions of the difficulty and applicability of digital and conventional implant impressions and their preferences including performance. Fifty undergraduate dental students at a dental school in Switzerland were randomly divided into two groups (2×25). Group A first took digital impressions in a standardized phantom model and then conventional impressions, while the procedures were reversed for Group B. Participants were asked to complete a VAS questionnaire (0-100) on the level of difficulty and applicability (user/patient-friendliness) of both techniques. They were asked which technique they preferred and perceived to be more efficient. A quotient of "effective scan time per software-recorded time" (TRIOS) was calculated as an objective quality indicator for intraoral optical scanning (IOS). The majority of students perceived IOS as easier than the conventional technique. Most (72%) preferred the digital approach using IOS to take the implant impression to the conventional method (12%) or had no preference (12%). Although total work was similar for males and females, the TRIOS quotient indicated that male students tended to use their time more efficiently. In this study, dental students with no clinical experience were very capable of acquiring digital tools, indicating that digital impression techniques can be included early in the dental curriculum to help them catch up with ongoing development in computer-assisted technologies used in oral rehabilitation.

What is dental ecology?

Teeth have long been used as indicators of primate ecology. Early work focused on the links between dental morphology, diet, and behavior, with more recent years emphasizing dental wear, microstructure, development, and biogeochemistry, to understand primate ecology. Our study of Lemur catta at the Beza Mahafaly Special Reserve, Madagascar, has revealed an unusual pattern of severe tooth wear and frequent tooth loss, primarily the result of consuming a fallback food for which these primates are not dentally adapted. Interpreting these data was only possible by combining our areas of expertise (dental anatomy [FC] and primate ecology [MS]). By integrating theoretical, methodological, and applied aspects of both areas of research, we adopted the term "dental ecology"-defined as the broad study of how teeth respond to the environment. Specifically, we view dental ecology as an interpretive framework using teeth as a vehicle for understanding an organism's ecology, which builds upon earlier work, but creates a new synthesis of anatomy and ecology that is only possible with detailed knowledge of living primates. This framework includes (1) identifying patterns of dental pathology and tooth use-wear, within the context of feeding ecology, behavior, habitat variation, and anthropogenic change, (2) assessing ways in which dental development and biogeochemical signals can reflect habitat, environmental change and/or stress, and (3) how dental microstructure and macro-morphology are adapted to, and reflect feeding ecology. Here we define dental ecology, provide a short summary of the development of this perspective, and place our new work into this context. Copyright © 2012 Wiley Periodicals, Inc.

Dental anxiety could impede dental treatment in children. Evidence shows that parents' fear of dentists contributes to children's anxiety towards dentists. The aim of the present study was to determine whether and to what extent: a) parents' anxiety and depression personality traits, b) parent's dental fear, and c) child personality traits can predict children's dental anxiety in an Italian population. One hundred and four children (5-14 years old) and one of their parents participated in the study. Well-known and validated questionnaires were administered to children (MCDASf, CFSS-DS, TAD) and parents (FDPQ, STAI Y1, Y2, and BDI-II). Dental anxiety is significantly associated with the anxiety personality trait and depression of the child and with parental fear of dental pain. A hierarchical regression analysis showed that, regardless of age and gender, the best predictor of child dental anxiety is parent's fear of dental pain, rather than relatively stable temperaments of the child. In line with the literature concerning adults, these findings highlight the children dental anxiety as a complex phenomena consisting of different components, including the child's personality traits (anxiety trait and depression) and parents' dental fear. Clinical implications of this evidence are discussed. © 2015 American Association of Public Health Dentistry.

To estimate responsibility loadings for a comprehensive list of dental services, providing a standardized unit of clinical work effort. Dentists (n = 2500) randomly sampled from the Australian Dental Association membership (2011) were randomly assigned to one of 25 panels. Panels were surveyed by questionnaires eliciting responsibility loadings for eight common dental services (core items) and approximately 12 other items unique to that questionnaire. In total, loadings were elicited for 299 items listed in the Australian Dental Schedule 9th Edition. Data were weighted to reflect the age and sex distribution of the workforce. To assess reliability, regression models assessed differences in core item loadings by panel assignment. Estimated loadings were described by reporting the median and mean. Response rate was 37%. Panel composition did not vary by practitioner characteristics. Core item loadings did not vary by panel assignment. Oral surgery and endodontic service areas had the highest proportion (91%) of services with median loadings ≥1.5, followed by prosthodontics (78%), periodontics (76%), orthodontics (63%), restorative (62%) and diagnostic services (31%). Preventive services had median loadings ≤1.25. Dental responsibility loadings estimated by this study can be applied in the development of relative value scales. © 2017 Australian Dental Association.

Background To investigate the role of geography (place of residence) as a moderator in the relationship between dental caries disease and treatment experience and dental fear in 16-year-olds living in Malaysia. Methods A multi-stage-stratified sampling method was employed. Five hundred and three, 16-year-olds from 6 government secondary schools participated in this study. The questionnaire examined participants’ demographic profile and assessed their dental fear using the Dental Fear Survey (DFS). The clinical examination consisted of the DMFT as the outcome measure of dental caries disease and treatment experience by a single examiner (ICC = 0.98). Structural equation modelling inspected the relationship between dental fear and dental caries disease and treatment experience. Results The mean DMFT was 2.76 (SD 3.25). The DT, MT and FT components were 0.64 (SD 1.25), 0.14 (SD 0.56) and 1.98 (SD 2.43) respectively. Rural compared with urban adolescents had significantly greater mean numbers of decayed and missing teeth. The mean DFS score was 40.8 (SD 12.4). Rural compared with urban adolescents had significantly higher mean scores for physical symptoms of dental fear. The correlation between dental fear (DFS) and dental caries disease and treatment experience (DMFT) was 0.29, p dental caries disease and treatment experience. The strength of the relationship between dental fear and dental caries disease and treatment experience varied in accordance with place of residence. Conclusion In conclusion a relationship between dental fear and dental caries disease and treatment experience was shown to exist in 16-year-old adolescents living in Malaysia. This study showed that the rural–urban dichotomy acted as a moderator upon this relationship. PMID:24621226

Full Text Available Context: To investigate the antibiotic prescribing training received by dental students, clinical experience in treating child patients, awareness of antibiotic prescribing guidelines, preparedness in antibiotic prescribing, and compliance with antibiotic prescribing guidelines for the management of dental infections in children. Methods: This was a cross-sectional study involving final year dentals students from Malaysian and Asian dental schools. A self-administered questionnaire consisting of five clinical case scenarios was e-mailed to all final year students at selected dental schools. Students′ responses were compared for each clinical case scenario with the prescribing guidelines of the American Academy of Pediatric Dentistry and the American Dental Association. Compliance in each scenario was tested for association with their preparedness in antibiotic prescribing, previous training on antibiotic prescribing and awareness of antibiotic prescribing guidelines using Chi-square test. Data collected were analyzed using SPSS statistics version 20. Results: A total of 108 completed responses were received. About 74 (69% students were from Malaysian dental schools. The compliance rate with prescribing guidelines ranged from 15.7% to 43.5%. Those attending Malaysian dental schools (47.3% and those who had treated child patient more often (46.3% were more likely (P < 0.05 to be aware of the guidelines. Those who had received antibiotic prescribing training (21.3% were more likely to think they were well prepared in antibiotic prescribing (P < 0.05. Conclusions: Final year dental students had low awareness and compliance with antibiotic prescribing guidelines. Further research is needed to investigate how compliance with the guidelines may be enhanced.

Dental radiology is quickly becoming integral to the standard of care in veterinary dentistry. This is not only because it is critical for proper patient care, but also because client expectations have increased. Furthermore, providing dental radiographs as a routine service can create significant practice income. This article details numerous conditions that are indications for dental radiographs. As you will see, dental radiographs are often critical for proper diagnosis and treatment. These conditions should not be viewed as unusual; they are present within all of our practices. When you choose not to radiograph these teeth, you leave behind painful pathology. Utilizing the knowledge gained from dental radiographs will both improve patient care and increase acceptance of treatment recommendations. Consequently, this leads to increased numbers of dental procedures performed at your practice.

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

Interprofessional and intraprofessional education (when students from two or more professions or within the same profession, respectively, learn about, from, and/or with each other) is crucial for effective interdisciplinary collaboration. The aims of this study were to assess the effectiveness of a clinical intraprofessional education program for dental and dental hygiene students, based on students' expectations and satisfaction with the program and patients' satisfaction with the team-based care. The pilot program was developed at the University of Tennessee Health Science Center College of Dentistry, where dental hygiene students were paired randomly with dental students scheduled for prophylaxis, scaling and root planing, or periodontal maintenance. Surveys with questions about the students' expectations and satisfaction were distributed to 89 senior dental students and 27 senior dental hygiene students before and after team-based procedures. Another survey was distributed to 17 patients asking about their satisfaction with the team-based care. All 27 dental hygiene students (100% response rate), 51 dental students (57.3% response rate), and all 17 patients (100% response rate) participated in the surveys. The results showed that both the dental and dental hygiene students had high expectations and were overall satisfied with the intraprofessional education. The students' expectations and perceived educational gap (difference between expectations and satisfaction) differed for the dental and dental hygiene students (ppatients were overwhelmingly satisfied with the team-based care. These results suggest that this intraprofessional practice model provided an effective educational experience for both dental and dental hygiene students and patients. The differences between the dental hygiene and dental students' expectations will help in the design of more effective training that promotes intraprofessional and interprofessional teamwork.

The importance of understanding barriers to dental attendance of adults in the UK was acknowledged in the first Adult Dental Health Survey in 1968 and has been investigated in all subsequent ADH surveys. In 1968, approximately 40% of dentate adults said they attended for a regular check-up; by 2009 this was 61%. Attendance patterns were associated with greater frequency of toothbrushing, use of additional dental hygiene products, lower plaque and calculus levels. Just under three-fifths of adults said they had tried to make an NHS dental appointment in the previous five years. The vast majority (92%) successfully received and attended an appointment, while a further 1% received an appointment but did not attend. The remaining 7% of adults were unable to make an appointment with an NHS dentist. The majority of adults were positive about their last visit to the dentist, with 80% of adults giving no negative feedback about their last dentist visit. Cost and anxiety were important barriers to care. Twenty-six percent of adults said the type of treatment they had opted for in the past had been affected by the cost and 19% said they had delayed dental treatment for the same reason. The 2009 survey data demonstrated a relationship between dental anxiety and dental attendance. Adults with extreme dental anxiety were more likely to attend only when they had trouble with their teeth (22%) than for a regular check-up.

The changing health care environment and societal imperatives indicate the need for transformative change within the dental hygiene profession to serve the emerging needs of the public. The American Dental Hygienists' Association is leading the way toward meaningful change. The American Dental Hygienists' Association (ADHA) has as its vision the integration of dental hygienists into the health care delivery system as essential primary care providers to expand access to oral health care. This article provides data on current dental hygiene education programs and those in development. Also included is a discussion regarding how the dental hygiene profession can better serve the health and wellness needs of society by transforming the way graduates are prepared for the future. ADHA's dental hygiene survey center data, policies and a futuristic analysis plus a review of the professional literature describe the current state of dental hygiene education and the profession. A discussion of societal, health care and educational trends that creates the imperative for transformation of the dental hygiene profession is provided. Ultimately, the purpose of advancing education in dental hygiene is to achieve better oral and overall health for more people. The profession's responsibility to the public includes evaluating its own ability to provide care and taking the steps necessary to ensure its maximum effectiveness. ADHA is leading this process for dental hygienists in diverse ways. It is imperative that the dental hygiene profession understands and embraces the changing health care environment. Through open dialog and the sharing of evidence the professional path will be determined along with forward movement for the benefit of society and the dental hygiene profession.

2013-01-01

In 1999, An Oral Health Survey of American Indian and Alaska Native (AI/AN) Dental Patients found that 79% of 2- to 5-year-olds had a history of tooth decay. The Alaska Native Tribal Health Consortium in collaboration with Alaska's Tribal Health Organizations (THO) developed a new and diverse dental workforce model to address AI/AN oral health disparities. This paper describes the workforce model and some experience to date of the Dental Health Aide (DHA) Initiative that was introduced under the federally sanctioned Community Health Aide Program in Alaska. These new dental team members work with THO dentists and hygienists to provide education, prevention and basic restorative services in a culturally appropriate manner. The DHA Initiative introduced 4 new dental provider types to Alaska: the Primary Dental Health Aide, the Expanded Function Dental Health Aide, the Dental Health Aide Hygienist and the Dental Health Aide Therapist. The scope of practice between the 4 different DHA providers varies vastly along with the required training and education requirements. DHAs are certified, not licensed, providers. Recertification occurs every 2 years and requires the completion of 24 hours of continuing education and continual competency evaluation. Dental Health Aides provide evidence-based prevention programs and dental care that improve access to oral health care and help address well-documented oral health disparities.

2014-01-01

The purpose of this study was to examine baccalaureate dental hygiene faculty members' attitudes and practices regarding student plagiarism. An email containing a link to a thirty-two-item survey was sent to fifty-two baccalaureate dental hygiene program directors in the United States; thirty of those agreed for their faculty members to participate. Of the 257 faculty members who received the survey link, 106 completed the survey, for a response rate of 41.2 percent. The responding faculty members reported thinking plagiarism is a rising concern in their dental hygiene programs (54.5 percent, 54/99). The majority said they check for plagiarism on student class assignment/projects (67.1 percent, 53/79). For those who did not check for plagiarism, 45.8 percent (11/24) stated it took "too much time to check" or it was "too hard to prove" (16.6 percent, 4/24). The most frequent form of student plagiarism observed by the respondents was "copying directly from a source electronically" (78.0 percent, 39/50). Most respondents reported checking for plagiarism through visual inspection (without technological assistance) (73.0 percent, 38/52). Of those who said they use plagiarism detection software/services, 44.4 percent (16/36) always recommended their students use plagiarism detection software/services to detect unintentional plagiarism. For those faculty members who caught students plagiarizing, 52.9 percent (27/51) reported they "always or often" handled the incident within their dental hygiene department, and 76.5 percent (39/51) said they had never reported the student's violation to an academic review board.

Dental anxiety is common among children. Although there is a wealth of research investigating childhood dental anxiety, little consideration has been given to the child's perspective. This qualitative study sought to explore with children their own experiences of dental anxiety using a cognitive behavioural therapy assessment model. Face-to-face, semi-structured interviews were conducted with dentally anxious children aged 11-16 years. The Five Areas model was used to inform the topic guide and analysis. Data were analysed using a framework approach. In total, 13 children were interviewed. Participants described their experiences of dental anxiety across multiple dimensions (situational factors and altered thoughts, feelings, physical symptoms, and behaviours). Participants placed considerable value on communication by dental professionals, with poor communication having a negative influence on dental anxiety and the dentist-patient relationship. This study confirms the Five Areas model as an applicable theoretical model for the assessment of childhood dental anxiety. Children provided insights about their own dental anxiety experiences that have not previously been described. © 2016 BSPD, IAPD and John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

1998-04-01

This paper describes CARL (Computer Assisted Relaxation Learning), a computerized, exposure-based therapy program for the treatment of dental injection fear. The CARL program operates primarily in two different modes; in vitro, which presents a video-taped exposure hierarchy, and in vivo, which presents scripts for a dentist or hygienist to use while working with a subject. Two additional modes are used to train subjects to use the program and to administer behavioral assessment tests. The program contains five different modules, which function to register a subject, train subjects to use physical and cognitive relaxation techniques, deliver an exposure hierarchy, question subjects about the helpfulness of each of the therapy components, and test for memory effects of anxiolytic medication. Nine subjects have completed the CARL therapy program and 1-yr follow-up as participants in a placebo-controlled clinical trial examining the effects of alprazolam on exposure therapy for dental injection phobia. All nine subjects were able to receive two dental injections, and all reduced their general fear of dental injections. Initial results therefore indicate that the CARL program successfully reduces dental injection fear.

Dental school finances: current status.

Crawford, W H

1986-05-01

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

2017-08-01

This study examines income inequalities in foregone dental care in 23 European countries during the years with global economic crisis. Associations between dental care coverage from public health budgets or social insurance, and income-related inequalities in perceived access to dental care, are analysed. Survey data 2008-2013 from 23 countries were combined with country data on macro-economic conditions and coverage for dental care. Foregone dental care was defined as self-reported abstentions from needed dental care because of costs or other crisis-related reasons. Age-standardized percentages reporting foregone dental care were estimated for respondents, age 20-74, in the lowest and highest income quartile. Associations between dental care coverage and income inequalities in foregone dental care, adjusted for macro-economic indicators, were examined by country-level regression models. In all 23 countries, respondents in the lowest income quartile reported significantly higher levels of foregone dental care than respondents in the highest quartile. During 2008-2013, income inequalities in foregone dental care widened significantly in 13 of 23 countries, but decreased in only three countries. Adjusted for countries' macro-economic situation and severity of the economic crisis, higher dental care coverage was significantly associated with smaller income inequalities in foregone dental care and less widening of these inequalities. Income-related inequalities in dental care have widened in Europe during the years with global economic crisis. Higher dental care coverage corresponded to less income-related inequalities in foregone dental care and less widening of these inequalities. © 2017 John Wiley & Sons A/S.

A trend towards increasingly new forms of dental practice has been observed in the FDI World Dental Federation. Elementary foundations such as the free dentist and therapy choice, and independent, free, self-responsible professional practice may be undermined. The current study is aimed at analyzing the general training framework, organization, and professional types of dental practice in the European Regional Organization (ERO) zone and at critically discussing selected aspects of changes in the dental profession. A questionnaire was developed by the ERO Working-Group "Liberal Dental Practice." Information about dental schools, professional organizations, dental practice regulations, and ambulatory healthcare centers was analyzed. Self-employed dental practice is the most common type of practice (51.7%). Dentists are allowed to work independently immediately after graduation (72.7%). Approximately one-third are organized as compulsory members in chambers/corporations. The density of dentists has a mean of 1,570 inhabitants per dentist. In most countries, there are no special rules for founding dental ambulatory healthcare centers. In a total of 353 universities of the ERO countries surveyed, 16,619 dentists per year were trained, with a trend toward a higher percentage of female students (63%). Despite modern forms of dental practice, the charter of the individual liberal dental profession (CED et al, 2013) should be respected and taken into account on the basis of ethical principles. The commercialization of the dental profession can be neutralized only by establishing and following well-defined ethical principles; oral healthcare quality can thus be ensured without the influence of third parties.

Dental OCT

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

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

Kvist, T; Zedrén-Sunemo, J; Graca, E; Dahllöf, G

2014-10-01

To study if treatment under general anaesthesia (GA) is associated with dental neglect or dental disability. This was a retrospective study. Dental records of all children in the age 0-6 years who underwent GA at a specialist paediatric dentistry clinic during 2006-2011 were studied with regard to decayed-missed-filled teeth, traumatic injuries, emergency visits, behaviour management problems and the history of attendance. The final sample consisted of 134 children. Matched controls were selected among recall patients who had not received treatment under GA. Fishers exact test or Pearson Chi-square test analysed response distribution and comparisons between groups, and for multivariate analyses, logistic regression was used. The results show that children treated under GA had significantly higher caries prevalence, apical periodontitis and infections due to pulpal necrosis. Dental neglect as well as dental disability was significantly more prevalent in the GA group compared to the control group. In a multivariate analysis with dental neglect as independent factor, dental disability was the only significant factor (p = 0.006). Children treated under general anaesthesia were significantly more often diagnosed with both dental neglect and dental disability. Dental disability was the only factor significantly related to dental neglect. There is a need for improved documentation in the dental records to better identify dental neglect and dental disability, and also a continued training of dentists regarding child protection.

Exploring Current and Future Roles of Non-Dental Professionals: Implications for Dental Hygiene Education.

Science.gov (United States)

Maxey, Hannah L; Farrell, Christine; Gwozdek, Anne

2017-09-01

The health care system is undergoing transformation in which oral health is not only valued as an aspect of overall health, but health care delivery systems are aligning to better deliver total patient care. As a result of this transformation, education for many non-dental professionals incorporates oral health content to prepare them to practice in comprehensive delivery models. While some non-dental professionals already incorporate oral health care in their service, many opportunities exist for expansion of oral health care delivery by other non-dental professionals, including radiologic technicians, nursing staff, and human services professionals. As non-dental professionals take on expanded roles in oral health care, the dental hygiene workforce must be prepared to practice in settings with new types of professionals. Dental hygiene curricula should prioritize interprofessional education to best prepare these students for practice in evolved delivery models. This article was written as part of the project "Advancing Dental Education in the 21 st Century."

Occupational noise is unavoidably produced from dental equipment, building facilities, and human voices in the dental environment. The purpose of this study was to investigate the effect of occupational noise exposure on the dental professionals' health condition. The psychoacoustics approach noise exposure assessment followed by the health risk assessment was carried on at the paediatric dentistry clinic and the dental laboratory in the Prince Philip Dental Hospital of Hong Kong. The A-weighted equivalent sound level, total loudness, and sharpness values were statistically significantly higher for the noise at the laboratory than that at the clinic. The degree of perceived influences and sharpness of noise were found to have the impacts on the dental professionals' working performance and health. Moreover, the risk of having a bad hearing state would a have 26% and 31% higher chance for a unit increment of the short-term and long-term impact scores, respectively. The dental professionals with the service length more than 10 years and the daily working hours of more than eight showed the highest risk to their hearing state. The worse the hearing state was, the worse the health state was found for the dental professionals. Also, the risk of dissatisfaction would be increased by 4.41 and 1.22 times for those who worked at the laboratory and a unit increment of the long-term impact score. The constructed health risk mode with the scientific and statistical evidence is hence important for the future noise management of environmental improvement.

2003-10-01

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

Full Text Available Background: Dental waste can be hazardous to humans and the environment. Objective: To determine the current status of dental waste management in private and public dental clinics and private dental offices in Shiraz, southern Iran. Methods: This cross-sectional study was conducted at the Shiraz University of Medical Sciences from February through June 2013. A stratified random sampling method was used to study 86 private offices, 14 private clinics and 10 public clinics. Types of waste studied included mercury and amalgam, lead foil packets, sharps, infectious tissues and fluids, pharmaceuticals and domestic waste materials. Compliance with established standards by the monitored dental offices and clinics and public clinics were compared. Results: 89.1% of dental offices and clinics disposed their infectious waste with domestic waste. Only 60% of centers used standard method for sharps disposal. None of the dental centers disposed their pharmaceutical waste and x-ray fixer waste by standard methods. Less than 10% of centers recycled the amalgam and lead foil pockets waste to the manufacture. Conclusion: Government agencies should establish monitoring programs for all dental offices and clinics to identify noncompliant activity and enforce recommended regulations.

Prabhu, Neeta T

2010-03-01

The goal of this study was to elicit the views of patients or parents\\/caregivers of patients with disabilities regarding access to dental care. A questionnaire was generated both from interviews with patients\\/parents\\/caregivers already treated under sedation or general anesthesia as well as by use of the Delphi technique with other stakeholders. One hundred thirteen patients from across six community dental clinics and one dental hospital were included. Approximately, 38% of the subjects used a general dental practitioner and 35% used the community dental service for their dental care, with only 27% using the hospital dental services. Overall waiting time for an appointment at the secondary care setting was longer than for the primary care clinics. There was a high rate of parent\\/caregiver satisfaction with dental services and only five patients reported any difficulty with travel and access to clinics. This study highlights the need for a greater investment in education and training to improve skills in the primary dental care sector.

Dental PACS development in Korea

International Nuclear Information System (INIS)

Kim, Eun Kyung

2008-01-01

Picture archiving and communication system (PACS) is an image information technology system for the transmission and storage of medical images. In Korea the first full PACS was installed at Samsung Medical Center in 1994, but, the rate of distribution was very slow. The government's approval for the medical insurance reimbursement for full PACS examinations in November 1999 became the turning point. Thereafter the number of hospitals with full PACS has steeply increased. In September of this year, PACS was installed at 906 medical institutes, including most of university hospitals and general hospitals. The first full dental PACS was installed at Wonkwang University Dental Hospital in 2002. Now ten out of eleven university dental hospitals implemented full dental PACS. The current status and technological factors of dental PACS in Korean university dental hospitals and the future perspectives of dental PACS are described.

Implementation of an adolescent risk behaviour assessment in an academic paediatric dental setting

Directory of Open Access Journals (Sweden)

Edna Perez

2017-09-01

Full Text Available Background Adolescents commonly engage in negative risk behaviours which could have serious implications on their oral and systemic health. Health care providers must be able to identify signs and comfortably question adolescents regarding these risk behaviours Aims Allow dental providers to administer a risk behavior questionnaire addressed towards adolescents to begin the transition from the pediatric to adult model and assist them in taking personal responsibility for their health. When negative behaviors are recognized, the goal is to help the adolescent by providing them with educational information, such as brochures or other resources related to the identified risks, and offering referrals to relevant providers. Methods A medical questionnaire to assess adolescent’s risk behaviors has been implemented at the University of Florida Pediatric Dental Clinic and is administered to patients 13+ as part of each examination appointment. A policy of confidentiality is discussed with the parent and informed consent obtained prior to conducting this questionnaire individually with the patient. Results During a period of over a year, the questionnaire has been administered by the pediatric dental faculty for a trial period; administration by the pediatric dental residents began this term and is currently ongoing. Conclusion Completion of the risk behavior questionnaire has provided an opportunity for teenagers to become more comfortable speaking individually with a dental provider. Identification of these risks allowed the pediatric dentist to help the patient seek appropriate care as they enter adulthood, and provide a more thorough approach towards the adolescent’s oral and general health.

An overview of dental radiology: a primer on dental radiology

1980-01-01

To provide medical and scientific background on certain selected technologies generally considered to be of particular significance, the National Center for Health Care Technology (NCHCT) has commissioned a series of overview papers. This is one of several projects entered into jointly by the Bureau of Radiological Health (BRH) and NCHCT relating to the use of radiation for health care. Dental radiation protection has been a long-time interest of BRH. Both past and on-going efforts to minimize population radiation exposure from electronic products have included specific action programs directed at minimizing unnecessary radiation exposure to the population from dental radiology. Current efforts in quality assurance and referral criteria are two aspects of NCHCT's own assessment of this technology which are described within the larger picture presented in this overview. The issues considered in this document go beyond the radiation exposure aspects of dental x-ray procedures. To be responsive to the informational needs of NCHCT, the assessment includes various other factors that influence the practice of dental radiology. It is hoped this analysis will serve as the basis for planning and conducting future programs to improve the practice of dental radiology

Evaluation of radiation effects on dental enamel hardness and dental restorative materials

Adachi, Lena Katekawa; Saiki, Mitiko; Campos, Tomie Nakakuki

2000-01-01

This research presents the results of the microhardness of human dental enamel and of the following dental restorative materials: three dental porcelains - Ceramco II, Finesse and Noritake, and two resin restorative materials - Artglass and Targis, for materials submitted to different times of irradiation at the IEA-R1m nuclear reactor under a thermal neutron flux of 10 12 n cm -2 .s -1 . The results obtained indicated that there is a decrease of the surface microhardness when the enamel is irradiated for 1 h and when dental materials are irradiated for 3 h. However, enamels irradiated for 30 min. did not show significant change of their surface hardness. Therefore, the selection of irradiation time is an important factor to be considered when irradiated teeth or dental materials are used in the investigations of their properties. (author)

OBJECTIVES: This study reports findings on the dental status and the prevalence of dental caries among a group of 85-year-old Danes from the Glostrup 1914 Cohort, Denmark. The purpose of the study was to analyse whether caries experience was related to number of teeth and to indicators...... of functional ability and cognitive function. METHODS: A total of 191 individuals (78 men and 113 women) participated in a cross-sectional population study conducted in 2000. Using mobile dental equipment, a clinical oral examination and an interview were administered to all participants in their homes...... and cognitive impairment tended to have more active caries than 85-year-olds with no impairment. CONCLUSIONS: A substantial proportion of 85-year-old individuals had retained a natural dentition; however, active dental caries is a problem of concern among the most elderly....

This cross-sectional study was to investigate correlations between molar incisor hypomineralisation (MIH), dental caries and child dental fear. The subjects in the study were representative samples of 8 and 14 year old children from three Greek cities (total N = 2335). Dental examinations were performed by one calibrated examiner in classrooms, after the children had brushed their teeth, using an intraoral mirror and artificial room light supplemented by a penlight. All the children completed the children's fear survey schedule-dental subscale (CFSS-DS) questionnaire. MIH scores were recorded using EAPD criteria and dental caries experience by DMFS/dmfs index. Data were analysed with the Chi-squared (χ (2)), Mann-Whitney and Spearman's rank correlation coefficient tests. The mean DMFS in children with MIH (8-year olds: 1.60 ± 2.01, 14-year olds: 4.60 ± 4.41) was statistically significantly higher than children without MIH (8-year olds: 1.01 ± 1.78, 14-year olds: 3.46 ± 4.28) (p MIH had statistically significantly higher mean DMFS scores than children with mild or no MIH (p MIH status (p = 0.332). Caries experience was associated with the MIH status of the first permanent molars in both age groups (p MIH (26.5 ± 9.6) (p = 0.339), regardless of MIH severity. A positive association between MIH and dental caries was confirmed and a lack of association found between MIH and dental fear in Greek children.

A humanistic environment for dental schools: what are dental students experiencing?

Quick, Karin K

2014-12-01

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

To determine first-year dental students' current motivation and attitudes for choosing the dental profession at the Faculty of Dental Medicine, Medical University - Sofia, Bulgaria. An anonymous questionnaire, consisting of 12 questions about students' socio-demographic profile and their motivation for choosing dentistry, was administered to 119 first-year dental students at the Faculty of Dental Medicine of the Medical University of Sofia. The study was conducted at the beginning of the 2012-2013 academic year. The data was processed and analyzed with the following software: Microsoft Windows Server 2008 R2; Microsoft SQL Server 2008; Internet Information Server 7.5.; Microsoft SharePoint Server 2010. The majority of the students (73%) were self-motivated for choosing dentistry as a career; 61% of them did not have relatives in the medical profession; 43% chose dental medicine because it is a prestigious, humane and noble profession; 50% - for financial security; 59% - because of the independence that it provides. There were no significant differences in the motivation between males and females. Independence, financial security and 'prestige' were the predominant motivating factors in this group of first-year dental students. Determining the reasons for choosing dentistry has important implications for the selection and training of students as well as for their future job satisfaction.

Blumer, Sigalit; Costa, Liora; Peretz, Benjamin

To present comparative study aims to assist the practitioner to choose between behavior modification (BM) techniques, pharmacologic sedation (N 2 O-O 2 alone or combined with midazolam 0.5 mg/ kg) or routine general anesthesia (GA) for the most successful approach in enabling pediatric dental care. Dental records of 56 children treated in a university dental clinic between 2006-2016 were reviewed, and data on age, gender, required treatment (amalgam restorations, composite restorations, pulpotomy, and stainless steel crowns [SSC]), treatment approaches and therapeutic success at final follow-up were retrieved. Treatment under GA had the best success rates compared to both BM and pharmacologic sedation. N 2 O-O 2 alone had a 6.1-fold greater risk of failure compared to N 2 O-O 2 +midazolam (p- <0.008). Amalgam restorations had a 2.61-fold greater risk of failure than SSC (p- <0.008). The GA mode yielded significantly greater success than the N 2 O-O 2 mode alone. There were no significant differences in success rates between GA and combined midazolam 0.5 mg/kg+N 2 O-O 2 . When choosing restoration material, it is important to remember the high success rate of SSC compared to amalgam restoration.

Lee, Robert J; Aminian, Amin; Brunton, Paul

2017-06-01

There is potential for gastro-oesophageal reflux disease (GORD) to be under-diagnosed by physicians. A quick, focused examination, requiring no special equipment, of a patients' dentition can assist in making a more accurate diagnosis where GORD is suspected. Guidance is provided for physicians as to what intra-oral signs are suggestive of intrinsic dental erosion, which is a clinical feature of GORD and its associated conditions. Use of this information will, it is suggested, improve outcomes for patients where GORD is suspected. © 2016 Royal Australasian College of Physicians.

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

The vicious cycle of dental fear: exploring the interplay between oral health, service utilization and dental fear

Directory of Open Access Journals (Sweden)

Spencer A John

2007-01-01

Full Text Available Abstract Background Based on the hypothesis that a vicious cycle of dental fear exists, whereby the consequences of fear tend to maintain that fear, the relationship between dental fear, self-reported oral health status and the use of dental services was explored. Methods The study used a telephone interview survey with interviews predominantly conducted in 2002. A random sample of 6,112 Australian residents aged 16 years and over was selected from 13 strata across all States and Territories. Data were weighted across strata and by age and sex to obtain unbiased population estimates. Results People with higher dental fear visited the dentist less often and indicated a longer expected time before visiting a dentist in the future. Higher dental fear was associated with greater perceived need for dental treatment, increased social impact of oral ill-health and worse self-rated oral health. Visiting patterns associated with higher dental fear were more likely to be symptom driven with dental visits more likely to be for a problem or for the relief of pain. All the relationships assumed by a vicious cycle of dental fear were significant. In all, 29.2% of people who were very afraid of going to the dentist had delayed dental visiting, poor oral health and symptom-driven treatment seeking compared to 11.6% of people with no dental fear. Conclusion Results are consistent with a hypothesised vicious cycle of dental fear whereby people with high dental fear are more likely to delay treatment, leading to more extensive dental problems and symptomatic visiting patterns which feed back into the maintenance or exacerbation of existing dental fear.

Public Opinions Regarding Advanced Dental Hygiene Practitioners in a High-Need State.

Walsh, Sarah E; Chubinski, Jennifer; Sallee, Toby; Rademacher, Eric W

2016-10-01

Purpose: The new Advanced Dental Hygiene Practitioner (ADHP) profession is expected to increase access to oral health care for the general population, particularly in rural and underserved areas. In order for this strategy to be successful, the public must feel comfortable with the care provided by ADHPs and seek out their services, yet consumer receptivity has been overlooked in the literature. The current study explores comfort with ADHPs for one high-need state: Kentucky. Methods: Consumer receptivity to the ADHP was assessed using a large, random sample telephone survey. As a point of comparison, respondents were first asked about their comfort with care provided by two other advanced practice clinicians already licensed in the state: advanced practice registered nurses (APRN) and physician assistants (PA). Results: After hearing a brief description of the profession, nearly 3 in 4 Kentucky adults said they would be somewhat (35.4%) or very (38.2%) comfortable seeing an ADHP for routine dental care. The total proportion of Kentucky adults who were comfortable seeking care from an ADHP (73.6%) was slightly less than the proportion indicating comfort seeing an APRN (79.7%) or PA (81.3%). Conclusion: Overall, this study demonstrates that adults are receptive to new models of care delivery and report high levels of comfort with ADHPs. Consumer concerns are unlikely to be a barrier to expanded licensure for dental hygienists in high-need areas like Kentucky. Copyright © 2016 The American Dental Hygienists’ Association.

Background/Objectives Rampant tooth decay has been reported among methamphetamine users. We investigated the prevalence of dental disease and associated risk behaviors in methamphetamine users compared to heroin users. Methods This pilot project is a cross-sectional study of an on-going cohort of young adult injection-drug users (IDUs) in San Francisco. An oral health questionnaire was administered by a research-assistant, and two dentists performed clinical examinations to record the Decayed-Missing-Filled-Surfaces (DMFS) index, presence of residual roots, the Simplified Oral Hygiene Index, and salivary hypofunction. Results The prevalence of dental disease among 58 young adult IDUs was strikingly high compared to the U.S. general population, however, there was no difference in the level of dental disease between the methamphetamine and heroin users in this study. The mean DMFS and number of decayed surfaces exceeded 28 in both groups. Conclusions While no difference in dental disease between methamphetamine and heroin users was detected, we found a high prevalence of caries and caries-associated behaviors in this sample of young adult IDUs. Clinical Implications Given the high level of dental disease observed in this population of young adult IDUs, one next step may be to explore the feasibility and effectiveness of providing low-intensity preventative measures (e.g., distribution of chlorhexidine rinses, xylitol gum, application of fluoride varnishes) through outreach workers.

Hashim, R

2011-06-01

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

Raja, G.H.; Malik, F.S.; Attaullah, M.; Bashir, U.

2015-01-01

Background: The assessment of dental anxiety among children will aid in dealing with management issues related to dental treatment. There is no study available from Pakistan on dental anxiety in children. The aim of this study was to assess the prevalence of dental anxiety in children attending a teaching dental hospital in Islamabad, Pakistan. Method: A cross-sectional study was conducted on 252 children aged between 5-10 years attending a dental clinic in a dental hospital in Islamabad, Pakistan. Dental anxiety was assessed by using the Faces Version of the Modified Child Dental Anxiety Scale. This scale uses faces as pictograms to indicate the levels of dental anxiety making it easier for children to answer the questionnaire. Results: A total of 252 children were observed for assessment of dental anxiety having mean age of 7.88±1.55 years with 123 (48.8 percentage) males and 129 (51.2 percentage) females. Out of these children 150 (59.5 percentage) had previously visited a dentist and 102 (40.5 percentage) had no experience with a dentist before; 38 percentage (95/252) of children had moderate and severe dental anxiety. Dental anxiety decreased significantly with age (p=0.0003). The difference in anxiety levels was not statistically significant between males and females and in different socio-economic status. Conclusion: This study has highlighted dental anxiety as a potential public health concern regarding children in Pakistan. Assessment of dental anxiety is a useful way to identify anxious dental patients. (author)

Changes in sick leave among Swedish dental patients after treatment for dental fear.

Science.gov (United States)

Hakeberg, M; Berggren, U

1993-03-01

The most obvious consequence of a genuine dental phobic reaction is the avoidance of necessary dental care. Previous research has indicated that such avoidance results in deterioration of the oral status, which subsequently worsens patients' well-being and quality of life. The authors' previous investigations have shown overt behavioural and social effects by an increased time spent on sick leave compared with the public experience. Self-reports by patients also indicated that the time spent on sick leave was reduced after successful treatment for dental fear. The present investigation assessed the frequency of sick leave days among patients with dental fear and avoidance with regard to successful or unsuccessful treatment for dental fear (subsequent regular dental visit habits). A sub-sample of the fear group was compared with a group of matched controls. Data were collected from the official register of the National Health Insurance Board. It was revealed that the number of sick leave days was significantly reduced after treatment for dental fear among treated patients. This effect was also confirmed by a significant post-treatment difference between treated patients and those who discontinued or never started treatment. When compared with a matched control group, the positive change was further supported by a significant pre-treatment difference and a non-significant post-treatment difference.

Dhima, Matilda; Petropoulos, Vicki C; Han, Rita K; Kinnunen, Taru; Wright, Robert F

2012-05-01

The goals of this study were to 1) evaluate dental students' perceptions of dental specialties, 2) identify factors that play an important role in students' decision to pursue specialty training or career choices, and 3) establish a baseline of students' perceptions of the dental fields with the best future in terms of salary, personal and patient quality of life, and overall impact on the dental profession. Surveys were distributed to 494 students at the University of Pennsylvania School of Dental Medicine. Data were collected from 380 traditional four-year students and thirty advanced standing students. Chi-square tests, multivariate analysis, and logistic regressions were used to determine associations and independent contributions of student demographics to their perceptions of dental specialties and factors influencing specialty training or career choices. Debt was a statistically significant factor (p<0.001) in choosing specialty training or career independent of gender, age, or class year. Enjoyment of providing care in a specialty or field was identified as the single most important factor in choosing a specialty career. Half of the respondents had decided not to specialize. Pursuing postdoctoral general dentistry training and private practice in general dentistry were the most commonly reported plans after completion of dental school. Suggestions are made for ways to inform students about specialty training.

How a modified approach to dental coding can benefit personal and professional development with improved clinical outcomes.

Science.gov (United States)

Lam, Raymond; Kruger, Estie; Tennant, Marc

2014-12-01

One disadvantage of the remarkable achievements in dentistry is that treatment options have never been more varied or confusing. This has made the concept of Evidenced Based Dentistry more applicable to modern dental practice. Despite merit in the concept whereby clinical decisions are guided by scientific evidence, there are problems with establishing a scientific base. This is no more challenging than in modern dentistry where the gap between rapidly developing products/procedures and its evidence base are widening. Furthermore, the burden of oral disease continues to remain high at the population level. These problems have prompted new approaches to enhancing research. The aim of this paper is to outline how a modified approach to dental coding may benefit clinical and population level research. Using publically assessable data obtained from the Australian Chronic Disease Dental Scheme and item codes contained within the Australian Schedule of Dental Services and Glossary, a suggested approach to dental informatics is illustrated. A selection of item codes have been selected and expanded with the addition of suffixes. These suffixes provided circumstantial information that will assist in assessing clinical outcomes such as success rates and prognosis. The use of item codes in administering the CDDS yielded a large database of item codes. These codes are amenable to dental informatics which has been shown to enhance research at both the clinical and population level. This is a cost effective method to supplement existing research methods. Copyright © 2014 Elsevier Inc. All rights reserved.

1998-01-01

The purpose of this study was to assess the representation of academically based diplomates of the American Board of Dental Public Health (ABDPH) and to identify their perceptions on the training of dental public health predoctoral faculty. Data were collected by a mailed, self-administered, 13-item questionnaire. The population was the 48 diplomates of the ABDPH as of March 1997 associated with academic institutions. Twenty of the 55 US dental schools had a diplomate of the ABDPH with a mean of 1.8 diplomates per school with a diplomate. An average of 4.5 full-time faculty members per school were associated with teaching dental public health. A master's degree in public health (MPH) was the most frequently suggested educational requirement for dental public health faculty. Continuing education courses were training needs perceived for dental public health faculty. The lack of time, money, and incentives, along with perceived rigidity of requirements for board certification, were reported as major barriers for faculty becoming dental public health board certified. Numerous challenges confront the development of a strong dental public health presence in US dental schools. These challenges include, among others, insufficient numbers of academic dental public health specialists and insufficient motivations to encourage promising candidates to pursue specialty status.

Confronting shibboleths of dental education.

Science.gov (United States)

Masella, Richard S

2005-10-01

Shibboleths are common expressions presented as indisputable truths. When used in educational discussions, they reflect "motherhood and apple pie" viewpoints and tend to bring debate to a halt. Use of shibboleths may precede a desired imposition of "locksteps" in educational programming and are easily perceived as paternalistic by recipients. Nine shibboleths are presented as common beliefs of dental faculty and administrators. Evidence contradicting the veracity of the "obvious truths" is offered. The traditional "splendid isolation" of dentistry contributes to parochialism and belief in false shibboleths. Sound principles of higher and health professions education, student learning, and dental practice apply to dental education as to all health disciplines. Student passivity in dental education is not the best preparation for proficiency in dental practice. The master teacher possesses a repertoire of methodologies specific to meeting defined educational objectives. Active learning experiences bear close resemblances to professional duties and responsibilities and internally motivate future doctors of dental medicine. The difficulty in achieving curricular change leads to curricular entrenchment. Dentistry and dental education should not trade their ethical high ground for the relatively low ethical standards of the business world. Principles of professional ethics should govern relationships between dentists, whether within the dental school workplace or in practice. Suggestions are made on how to confront shibboleths in dental school settings.

Even though English is most frequently the common language when the patient's native language differs from that of a dentist, the opportunities for Japanese undergraduate dental students to learn dental English are now quite limited. The purposes of our study were to investigate: the effectiveness and feasibility of the computer-assisted simulation materials as one solution strategy for dental English education in Japan, and the needs and demands for dental English from the learners' side. Interactive simulation materials for medical interviews in English and clinical cases which were translated to English, were delivered via Learning Management System (LMS) to nineteen trainee residents of dentistry (residents). Evaluation for the materials, learners' knowledge and interests in the contents, and ease of operation were obtained by post-questionnaire (response rates were 100% and 95%, respectively). Both questionnaire-surveys received positive feedback toward the materials, yet 47% answered that they lacked the level of knowledge about contents of the medical interview in English. Results were sufficient to suggest that the residents would like to have the opportunity to study or practice medical interview in English, or English related to dentistry, and that the simulation materials could be one of the solution strategies for opportunity provision.

Objective: To evaluate the dental anxiety levels and to assess its correlation with self-assessed dental status and treatment needs of patients. Methods: The study was conducted at the Out Patient Department of Dr. Ishrat-ul-Ebad Khan Institute of Oral Health Sciences, Karachi. Using non-probability quota sampling, the study included the first 32 patients between 18 and 35 years of age, visiting the facility. Over a period of one month (22 working days) 704 patients comprised the study population. They were interviewed using a structured questionnaire to self-assess their dental anxiety levels, oral health status and treatment needs. The data was analysed using SPSS 17.0 with descriptive frequencies and chi-square test. Results: Of the total participants, 650 (92.32%) patients provided consent. Average dental anxiety scale score was 12.46, representing high anxiety score. There were 174 (26.8%) smokers; only 234 (36%) had visited a dentist less than a year ago; 385 (59.2%) considered their dental health to be satisfactory; 306 (47.1%) thought of their treatment needs to be little'; 222 (34.2%) brushed their teeth twice daily. Dental anxiety was statistically significant with treatment needs and dental status. Relation of tooth-brushing with last dental visit and treatment needs was also found to be significant. Conclusion: A high level of dental anxiety was observed among the study population. The dental professionals should seek ways to help dentally anxious individuals. (author)

Successful treatment of generalized refractory chronic periodontitis through discontinuation of waxed or coated dental floss use: A report of 4 cases.

Science.gov (United States)

Kelekis-Cholakis, Anastasia; Perry, John B; Pfeffer, Lorraine; Millete, Amy

2016-12-01

Generalized refractory chronic periodontitis is a periodontal condition that is resistant to conventional therapy. Management of this condition often is frustrating to both the patient and the clinician. The authors present 4 cases of generalized refractory chronic periodontitis characterized by an inflammatory gingival response and progressive bone loss that did not respond to extensive periodontal treatments and regular periodontal care. Histologic examination of affected gingival tissue revealed an abundance of plasma cells, a feature seen in certain oral contact hypersensitivity reactions. The authors suspected that waxed or coated dental floss was the offending contactant, and its removal from the patients' oral hygiene regimens resulted in a dramatic improvement of the periodontal characteristics. In cases of periodontal disease as described in this report, dental practitioners should consider the possibility of a contact hypersensitivity reaction to waxed or coated dental floss, whereby the floss exacerbates the condition instead of assisting in its resolution.

Little is known about dental case managers as few programs have been scientifically evaluated. The goal of this study was to explore the impact of dental case manager on retention in dental care and completion of treatment plans, while specifically exploring the number of dental case manager encounters. Fourteen programs enrolled people with HIV/AIDS (PLWHA) in dental care and a longitudinal study between 2007 and 2009. The 758 participants had a total of 2715 encounters with a dental case manager over twelve months: 29% had a single encounter; 21% had two; 27% had 3-4 and; 23% had 5-29 encounters. Adjusting for baseline characteristics, participants receiving more encounters were significantly more likely to complete their Phase 1 treatment plan, be retained in dental care, and experience improvements in overall oral health status. Organizations considering efforts to improve the oral health of vulnerable, hard-to-engage populations should consider these findings when planning interventions. ©2012 Special Care Dentistry Association and Wiley Periodicals, Inc.

The aim of this study was to examine the clinical characteristics of dental emergency patients who visited a university hospital emergency center and to evaluate the incidence of dental trauma. A retrospective chart review of patients with dental complaints and who visited the Seoul National University Bundang Hospital (SNUBH) emergency center in Gyeonggi-do, Korea, from January 2009 to December 2009 was conducted. Information regarding age, gender, the time, day, and month of presentation, diagnosis, treatment, and follow up was collected and analyzed. One thousand four hundred twenty-five patients with dental problems visited the SNUBH emergency center. Dental patients accounted for 1.47% of the total 96,708 patients at the emergency center. The male-to-female ratio was 1.68:1, with a considerably larger number of male patients (62.7%). The age distribution peak was at 0-9 years (27.5%), followed by patients in their forties (14.1%). The number of patients visiting the dental emergency center peaked in May (14.2%), on Sundays (22.4%), and between 2100 and 2400 h (20.8%). The patients' chief complaints were as follows: dental trauma, dental infection, oral bleeding, and temporomandibular joint disorder (TMD). The prevalence of dental trauma was 66%. The reasons for dental emergency visits included the following: dental trauma, dental infection, oral bleeding, and TMD, with 66% of the patients requiring management of dental trauma. It is important that dentists make a prompt, accurate diagnosis and initiate effective treatment in case of dental emergencies, especially dental trauma. © 2011 John Wiley & Sons A/S.

The Ukrainian Dental Market: Characteristics of Demand for Services in the Segment of Dental Implantation

Directory of Open Access Journals (Sweden)

Slipchenko Tetiana O.

2017-05-01

Full Text Available The article is aimed at analyzing the market for dental services in Ukraine in the implantology segment, studying the demand factors for these services and developing a system of measures to manage the demand for dental implantation services. It has been proven that the market for dental services according to a complex of its attributes is more in line with the type of market of monopolistic competition. One of the promising ways of developing the dental market is to transform producers of dental services into the vertically integrated holdings. As one of the specific features of the dental services market is allocated the asymmetry of information, which leads to a conflict between the medical and economic interests of dentists. The price and non-price factors of demand for dental implantation services were determined, the prime cost structure of a dental service was analyzed. The characteristic attributes of a medical service have been defined as consistently defined actions or a complex of actions by medical personnel aimed at prevention, diagnosis, treatment, and rehabilitation, which have a self-contained complete meaning and a certain price.

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

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.

2012-01-01

Since leadership is an essential part of the oral health professions, oral health educators can play an essential role in establishing a culture of leadership and in mentoring students to prepare them for future leadership roles within the profession. However, leadership training for oral health professionals is a relatively new concept and is frequently not found within dental and dental hygiene curricula. The purpose of this article is to propose several models for leadership training that are specific to the oral health professions. The authors hope that providing an overview of leadership programs in academic dental institutions will encourage all U.S. and Canadian dental schools to begin developing a culture that promotes leadership development.

BACKGROUND. The change towards a more Westernised diet in Libya may increase the risk of caries and erosion in children. AIMS. To investigate any association between dental caries, dental erosion, and potential dietary risk factors in Libyan schoolchildren. METHODS. A random sample of 791 schoolchildren aged 12 years underwent dental examination for caries and erosion and completed a questionnaire to provide dietary data. Dental caries was assessed using the WHO (Oral Health Surveys: Basic Methods, 1997) criteria. Erosion was assessed using UK National Diet and Nutrition Survey (NDNS, Young People Aged 4-18 years. Volume 2: Report of the Oral Health Survey, 2000) criteria. Associations between caries and dietary variables were investigated through bivariate and multivariate analyses. RESULTS. Of the 791 12-year olds, 57.8% (457) had caries experience and 40.8% (323) had experience of erosion. One hundred and ninety-two subjects (42%) of the subjects with caries experience also had erosion, whilst 131 subjects (39.2%) of the 334 without caries had clinical signs of erosion (P = 0.464; OR, 1.123; 95% CI, 0.842, 1.497). There was no statistically significantly relationship between dental caries and dental erosion. Frequency of consumption of fruit-based sugared drinks was statistically significantly positively associated with experience of caries (P = 0.002). CONCLUSIONS. Dental caries experience was associated with frequency of consumption of sugared dietary items but not with dental erosion. © 2011 The Authors.

This study evaluated the effect of dental education on oral health-related attitudes and behavior of students in a five-year dental program in Peru. A survey using the Hiroshima University-Dental Behavioral Inventory (HU-DBI), which consists of twenty dichotomous responses (agree-disagree) regarding oral health behavior and attitudes, was completed by Year 1 and Year 5 dental students at the Universidad Inca Garcilaso de la Vega in Lima, Peru. A total of 153 Year 1 students and 120 Year 5 students responded to the Spanish version of the HU-DBI questionnaire. The data were analyzed using chi-square tests and logistic regression analyses. Compared to the Year 1 students, the Year 5 dental students were more likely to agree with questions such as "I think I can clean my teeth well without using toothpaste" (OR=0.24, 95% CI: 0.10-0.58); "I have used a dye to see how clean my teeth are" (OR=0.19, 95% CI: 0.10-0.36); and "I have had my dentist tell me that I brush very well" (OR=0.34, 95% CI: 0.17-0.69). Overall, the data showed that the curriculum in this dental school in Peru resulted in more positive oral health-related attitudes and behavior among Year 5 dental students compared to those of Year 1 dental students.

Kennedy, R; Murray, C; Leichter, J

Among other restorative strategies, the Accident Compensation Corporation (ACC) provides benefits for dental implant treatment to replace teeth lost as a result of trauma. While ACC has funded over 15,000 dental implants since 2002, the outcomes of this treatment and patient perceptions of this treatment have not been investigated. The aim of this study was to investigate the perceptions of the dental implant treatment outcomes and reasons for failure to complete restorative treatment in patients who had undergone trauma-related implant surgery funded by ACC between February 2006 and September 2009, but had not completed the prosthetic component of the treatment. A randomly selected sample of 399 patients, who had undergone dental implant surgery but not completed the crown restoration, was identified from the ACC database. These individuals were contacted by mail for expressions of interest and 181 clients were interviewed by telephone. Responses to open-ended questions were entered into an Excel spreadsheet and analysed using a general inductive technique. A common emergent theme was the high level of satisfaction expressed by participants with the implant process, however just under half of those responding felt they had been pushed into having implants and were given the impression that this was the only treatment ACC paid for. The cost of the prosthetic phase of the treatment and surgical complications were identified as the primary reasons why participants failed to complete the restorative phase of treatment, after completing the surgical phase. The results highlighted the need to better inform patients of their treatment options and to allow time for them to process this information before progressing with care. A patient decision tool may help to give greater ownership of the treatment options. Newly implemented protocols to assist dentists to better assess treatment needs may also assist in achieving improvements in perceived treatment outcomes for

Effects of a proposed rural dental school on regional dental workforce and access to care.

Science.gov (United States)

Wanchek, Tanya N; Rephann, Terance J

2013-01-01

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

A systematic review was conducted to analyze Brazilian scientific and technological production related to the dental materials field over the past 50 years. This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (Prisma) statement. Searches were performed until December 2014 in six databases: MedLine (PubMed), Scopus, LILACS, IBECS, BBO, and the Cochrane Library. Additionally, the Brazilian patent database (INPI - Instituto Nacional de Propriedade Industrial) was screened in order to get an overview of Brazilian technological development in the dental materials field. Two reviewers independently analyzed the documents. Only studies and patents related to dental materials were included in this review. Data regarding the material category, dental specialty, number of documents and patents, filiation countries, and the number of citations were tabulated and analyzed in Microsoft Office Excel (Microsoft Corporation, Redmond, Washington, United States). A total of 115,806 studies and 53 patents were related to dental materials and were included in this review. Brazil had 8% affiliation in studies related to dental materials, and the majority of the papers published were related to dental implants (1,137 papers), synthetic resins (681 papers), dental cements (440 papers), dental alloys (392 papers) and dental adhesives (361 papers). The Brazilian technological development with patented dental materials was smaller than the scientific production. The most patented type of material was dental alloys (11 patents), followed by dental implants (8 patents) and composite resins (7 patents). Dental materials science has had a substantial number of records, demonstrating an important presence in scientific and technological development of dentistry. In addition, it is important to approximate the relationship between academia and industry to expand the technological development in countries such as Brazil.

Dental students--dental advocates.

Science.gov (United States)

Bensch, Brittany

2010-01-01

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

The current political environment in the nation's capital threatens federal support for programs vital to the academic dental community. To develop a strong cadre of advocates who can deliver an effective and unified message to members of Congress on behalf of dental education and dental research, the American Dental Education Association (ADEA) and the American Association for Dental Research (AADR) created a new organizational structure: the National Oral Health Advocacy Committee (NOHAC) and the National Advocacy Network (NAN). The basic skills and knowledge required to function as an effective advocate include an understanding of the political environment, a working knowledge of the legislative processes and the political players, and the ability to build and work with grassroots networks and coalitions. NOHAC and NAN are designed to provide leadership in these areas to support effective advocacy for dental education and dental research.

A national analysis of dental waiting lists and point-in-time geographic access to subsidised dental care: can geographic access be improved by offering public dental care through private dental clinics?

2017-01-01

Australia is one of the least densely populated countries in the world, with a population concentrated on or around coastal areas. Up to 33% of the Australian population are likely to have untreated dental decay, while people with inadequate dentition (fewer than 21 teeth) account for up to 34% of Australian adults. Historically, inadequate access to public dental care has resulted in long waiting lists, received much media coverage and been the subject of a new federal and state initiative. The objective of this research was to gauge the potential for reducing the national dental waiting list through geographical advantage, which could arise from subcontracting the delivery of subsidised dental care to the existing network of private dental clinics across Australia. Eligible population data were collected from the Australian Bureau of Statistics website. Waiting list data from across Australia were collected from publicly available sources and confirmed through direct communication with each individual state or territory dental health body. Quantum geographic information system software was used to map distribution of the eligible population across Australia by statistical area, and to plot locations of government and private dental clinics. Catchment areas of 5 km for metropolitan clinics and 5 km and 50 km for rural clinics were defined. The number of people on the waiting list and those eligible for subsidised dental care covered by each of the catchment areas was calculated. Percentage of the eligible population and those on the waiting list that could benefit from the potential improvement in geographic access was ascertained for metropolitan and rural residents. Fifty three percent of people on the waiting list resided within metropolitan areas. Rural and remote residents made up 47% of the population waiting to receive care.

Dental caries's diagnosis is a major dentistry problem from the clinic point of view. The laser beam on the region of 655 nm induces the fluorescence of the compounds present in the hard tissue, quantifying differences between sound and carious enamel and dentine. Diagnodent (Kavo, Germany), showed to be effective regarding dental caries's diagnosis in the present research sampling. The Er:YAG laser (Kavo Key Laser 2, Germany) performed efficient cavity preparations in caries lesions of I and V class type, using up energies that ranged from 300 mJ to 350 mJ with 4 Hz repetition rate for the enamel; and from 250 mJ to 300 mJ with 4 Hz repetition rate for the dentine, and with 80 mJ with 6 Hz of repetition rate for laser conditioning. In the Er:YAG laser preparations no patient was anesthetized even when there were deeper cavities, and the maximum degree of pain ( which ranged from 0 to 10) was 4. In the control group with conventional high-speed drill two patients were anesthetized and the maximum degree of pain was 7. Restorations performed by conventional method of composite were equally satisfying both in caries groups of I and V class type and in the control group. The laser application in the operative dentistry office as a new method of diagnosis and dental preparations should be a good alternative to the use of the conventional dental drill. Nevertheless, dentistry practice has a lot to improve from technology progress, as well as new researches on laser dentistry are necessary in a long term. New types of lasers will come about and will increasingly improve the dental practice assistance and procedures quality. (author)

Dental caries, age and anxiety: factors influencing sedation choice for children attending for emergency dental care.

Science.gov (United States)

Carson, P; Freeman, R

2001-02-01

The aim of the study was to examine how physical (dental caries) and psychosocial (age, dental anxiety and dental health behaviour) factors, associated with child and parent, influenced dentists' sedation choice when a child presents in pain. 600 parents whose children were aged between 5 and 11 years took part: 200 attended for routine dental care (RDC); the remaining 400 attended as emergency patients and were offered either dental general anaesthesia (DGA) or relative analgesia (RA). The subjects were approached and invited to take part. The researcher was blind as to the child's pattern of dental attendance and the type of sedation offered. All parents and children completed self-reported ratings of dental anxiety. The children's teeth were examined to determine past and present dental caries experience. The results showed that children who were offered DGA had greater experience of dentinal caries, were younger and dentally anxious. The children offered RA were older, had a higher frequency of brushing their teeth with fluoride toothpaste and were also dentally anxious. Discriminant analysis showed that 2 canonical functions provided clear categorisation of the three treatment groups. Function 1 was a physical (dental caries) factor, which was related to the child's experience of dentinal caries. Function 2 was a psychosocial factor, which was related to the child's age, dental anxiety and frequency of tooth brushing. A greater proportion of the variance in the treatment offered was explained by Function 1, suggesting that the most important factor in the decision to offer DGA was dentinal caries. Function 2 was of lesser importance. The findings have implications for the type of sedation offered to children presenting for emergency care. These children may not otherwise receive treatment and the need to provide less anxiety provoking forms of sedation must be promoted. By doing so, parents who have only brought their children when in pain may take advantage

Dental caries is a biofilm-mediated, sugar-driven, multifactorial, dynamic disease that results in the phasic demineralization and remineralization of dental hard tissues. Caries can occur throughout life, both in primary and permanent dentitions, and can damage the tooth crown and, in later life......, exposed root surfaces. The balance between pathological and protective factors influences the initiation and progression of caries. This interplay between factors underpins the classification of individuals and groups into caries risk categories, allowing an increasingly tailored approach to care. Dental...... caries is an unevenly distributed, preventable disease with considerable economic and quality-of-life burdens. The daily use of fluoride toothpaste is seen as the main reason for the overall decline of caries worldwide over recent decades. This Primer aims to provide a global overview of caries...

Dental Anomalies: An Update

2016-01-01

Full Text Available Dental anomalies are usual congenital malformation that can happen either as isolated findings or as a part of a syndrome. Developmental anomalies influencing the morphology exists in both deciduous and permanent dentition and shows different forms such as gemination, fusion, concrescence, dilaceration, dens evaginatus (DE, enamel pearls, taurodontism or peg-shaped laterals. All These anomalies have clinical significance concerning aesthetics, malocclusion and more necessary preparing of the development of dental decays and oral diseases. Through a search in PubMed, Google, Scopus and Medline, a total of eighty original research papers during 1928-2016 were found with the keywords such as dental anomaly, syndrome, tooth and hypodontia. One hundred review titles were identified, eighty reviews were retrieved that were finally included as being relevant and of sufficient quality. In this review, dental anomalies including gemination, fusion, concrescence, dilaceration, dens invaginatus, DE, taurodontism, enamel pearls, fluorosis, peg-shaped laterals, dentinal dysplasia, regional odontodysplasia and hypodontia are discussed. Diagnosing dental abnormality needs a thorough evaluation of the patient, involving a medical, dental, familial and clinical history. Clinical examination and radiographic evaluation and in some of the cases, specific laboratory tests are also needed. Developmental dental anomalies require careful examination and treatment planning. Where one anomaly is present, clinicians should suspect that other anomalies may also be present. Moreover, careful clinical and radiographical examination is required. Furthermore, more complex cases need multidisciplinary planning and treatment.

Curtis, Donald A; Jayanetti, Jay; Chu, Raymond; Staninec, Michal

2012-01-01

The clinical signs of dental erosion are initially subtle, yet often progress because the patient remains asymptomatic, unaware and uninformed. Erosion typically works synergistically with abrasion and attrition to cause loss of tooth structure, making diagnosis and management complex. The purpose of this article is to outline clinical examples of patients with dental erosion that highlight the strategy of early identification, patient education and conservative restorative management. Dental erosion is defined as the pathologic chronic loss of dental hard tissues as a result of the chemical influence of exogenous or endogenous acids without bacterial involvement. Like caries or periodontal disease, erosion has a multifactorial etiology and requires a thorough history and examination for diagnosis. It also requires patient understanding and compliance for improved outcomes. Erosion can affect the loss of tooth structure in isolation of other cofactors, but most often works in synergy with abrasion and attrition in the loss of tooth structure (Table 1). Although erosion is thought to be an underlying etiology of dentin sensitivity, erosion and loss of tooth structure often occurs with few symptoms. The purpose of this article is threefold: first, to outline existing barriers that may limit early management of dental erosion. Second, to review the clinical assessment required to establish a diagnosis of erosion. And third, to outline clinical examples that review options to restore lost tooth structure. The authors have included illustrations they hope will be used to improve patient understanding and motivation in the early management of dental erosion.

The aim of this study was to evaluate whether there is an association between risk behavior for eating disorders (EDs) and dental erosion and caries. A controlled cross-sectional study was conducted in Brazil, involving 850 randomly selected female adolescents. After evaluating risk behavior for eating disorders through the Bulimic Investigatory Test of Edinburgh, 12 adolescents were identified with severe risk behavior for EDs and matched to 48 adolescents without such risk. Dental examinations, anthropometric measurements, and eating habits and oral hygiene were performed. Adolescents with high severity eating disorder condition were not more likely to show dental caries ( p = 0.329; OR = 2.2, 95% CI: 0.35-13.72) or dental erosion ( p = 0.590; OR = 2.33; 95% CI: 0.56-9.70). Adolescents with high body mass index (BMI) were five times more likely to have high severity eating disorder condition ( p = 0.031; OR = 5.1; 95% CI: 1.61-23.07). Therefore, high severity risk behavior for EDs was not significantly associated with dental caries and dental erosion. However, high BMI was a risk factor for developing eating disorders and should be an alert for individuals with this condition.

What Will Dental Practice Be Like In 2025? Will You Help Dental Hypotheses Find Answers

Edward F. Rossomando

2011-02-01

Full Text Available As a result of the rapid acceptance of digital dental equipment, the dental office of 2011 looks very different from that of 1900. Despite these changes, the general dentist of 2011 performs almost the same functions as in 1900 namely the restoration of decayed teeth and the replacement of those lost due to disease. In addition to changes in technology, the last few decades of the 20th century ushered in a revolution in biology leading to the development of a genomic basis of dental disease and the development of bio-based diagnostics and therapeutics. In 2011 few if any of these bio-discoveries have changed dental practice but by 2025 we expect they will. In this editorial, Dental Hypotheses asks readers to “hypothesize” on what dental practice will be like in 2025.

Minority children and children from lower income families are more likely to experience the burden of oral disease. Since oral disease reduces quality of life, it is a priority to utilize preventive dental services. The research questions ask if affiliated practice increases utilization of preventive dental services by underserved children from birth to 18 years of age, and what the barriers to receiving preventive dental services are and their level of importance. A survey was administered to parents/guardians of patients from birth to 18 years of age who received preventive dental services from Catholic Healthcare West East Valley Children's Dental Clinic, an affiliated practice dental clinic in Chandler, Arizona. Thirty-four surveys were completed: 21 completed in English and 13 completed in Spanish. The data was analyzed to provide descriptive statistics and non-parametrically analyzed using the Friedman's, Kendall's W and Wilcoxon Signed Ranks Tests. The cost of preventive dental services is more important to this population than both convenience of appointment time and distance traveled. As the cost increases for preventive dental services, this population will utilize preventive dental services less frequently. The study indicated that the increase of self-reported utilization of preventive dental services by underserved children, ranging in age from birth to 18 years old, in Arizona affiliated practice dental clinics, was primarily impacted by perceived reduced costs of receiving care. Funding efforts, reimbursement mechanisms and legislative policies should support this dental care delivery model to provide care to underserved children, adults and seniors throughout the U.S.

People with disabilities experience barriers to dental care, which may vary depending on type of disability and disability complexity (e.g., impact on activities of daily living). The purpose of this study was to examine differences in dental insurance, receipt of dental checkups, and delayed and unmet needs for dental care by type and complexity of disability. We conducted cross-sectional analysis of 2002-2011 data from the Medical Expenditure Panel Survey. Multivariable logistic regression analyses compared adults ages 18-64 in five disability type groups (physical, cognitive, vision, hearing, or multiple disabilities) to those with no disabilities, and compared people with complex activity limitations to those without complex limitations. All disability types except hearing had significantly higher adjusted odds of being without dental insurance, as did people with complex activity limitations. All disability groups except those with cognitive disabilities had increased odds of receiving dental checkups less than once a year. Similarly, all disability groups were at increased risk of both delayed and unmet needs for dental care. Odds ratios were generally highest for people with multiple types of disabilities. There are significant disparities in having dental insurance and receiving dental care for adults with disabilities, especially those with multiple types of disabilities, after controlling for socioeconomic and demographic differences. Further, disparities in care were apparent even when controlling for presence of dental insurance. © 2016 American Association of Public Health Dentistry.

The histomorphometric test is the gold standard for dental implant stability quantification; however, it is invasive, and therefore, it is inapplicable to clinical patients. Consequently, accurate and objective alternative methods are required. Resonance frequency analysis (RFA) and digital radiographic analysis are noninvasive methods with excellent objectivity and reproducibility. To analyze the correlation between the radiographic analysis of alveolar bone density around a dental implant and the resonance frequency of the dental implant. Digital radiographic images for 35 samples were obtained, and the resonance frequency of the dental implant was acquired using Osstell ISQ immediately after dental implant placement and on third-month follow-up. The alveolar bone density around the dental implant was subsequently analyzed using SIDEXIS-XG software. No significant correlation was reported between the alveolar bone density around the dental implant and the resonance frequency of the dental implant (r = -0.102 at baseline, r = 0.146 at follow-up, p > 0.05). However, the alveolar bone density and resonance frequency showed a significant difference throughout the healing period (p = 0.005 and p = 0.000, respectively). Conclusion: Digital dental radiographs and Osstell ISQ showed excellent objectivity and reproducibility in quantifying dental implant stability. Nonetheless, no significant correlation was observed between the results obtained using these two methods.

The assessment of influence of silver-free, fluor releasing dental materials on dental plaque bacteria quantity. 17 patients were included into the study. 51 restorations were placed following manufacturers recommendations. Following materials were used: conventional glassionomer Ketac-Molar ESPE, resin modified glassionomer Fuji II LC GC and fluor containing composite Charisma Heraeus Kulzer Class V restorations were placed in following teeth of upper and lower jaw: canines, first bicuspids, second bicuspids. Sound enamel was a control. After 10 weeks the 72 hours old dental plaque was collected from surface of restorations and control using sterile probe. Total amount of 68 dental plaques were investigated. Each plaque was placed on scaled and sterile aluminum foil. The moist weight of dental plaque was scaled. Dental plaque was moved into 7 ml 0.85% NaCl solution reduced by cystein chlorine hydrogen and disintegrated by ultrasounds (power:100 Watt, wave amplitude: 5 micorm). The suspension of dental plaque was serially diluted from 10(-4) to 10(-5) in sterile 0,85% NaCl solution, and seeded with amount of 0.1 ml on appropriate base. In dental plaque trials the amount of cariogenic bacteria was calculated--Streptococcus mutans, Streptococcus, Lactobacillus, Veillonella and Neisseria, and also total amount of aerobic and anaerobic bacteria was measured. Microbiologic studies were performed in Institute of Microbiology, Medical University, Łódź. Statistical analysis of collected data was accomplished. In 72 hours old dental plaques collected from the surfaces of Ketac -Molar, Fuji II LC, Charisma after 10 weeks since being placed into the class V cavity, results show no statistically significant differences in the amount of Streptococcus mutans, Streptococcus spp., Lactobacillus spp., Veillonella spp., Neisseria spp, in total amount of aerobic and anaerobic bacteria and in the quantity proportion of Streptococcus mutans versus Streptococcus spp. in comparison

To examine the amount of heterogeneity in patients' preferences for dental care, what factors affect their preferences, and how much they would be willing to pay for improvement in specific dental care attributes. A discrete choice experiment (DCE) was used to elicit patients' preferences. Three alternative dental care services that differed in the type of care provider, treatment explanation, dental staff behavior, waiting time and treatment cost were described to patients. Patients (n=265) were asked to choose their preferred alternative. The study was conducted at a public dental clinic of the School of Dental Medicine, University of Zagreb. Mixed logit and latent class models were used for analysis. On average, the patients would be willing to pay €45 for getting a detailed explanation of treatment over no explanation. This was the most valued attribute of dental care, followed by dental staff behavior with marginal willingness-to-pay (WTP) of €28. Dental care provided by the faculty members and private dental care were valued similarly, while student-provided care was valued €23 less. Patients also disliked longer waiting time in the office, but this was the least important attribute. Four classes of patients with distinct preferences for dental care were identified. Older and/or more educated patients tended to give relatively less importance to treatment explanation. Higher education was also associated with a higher propensity to substitute faculty dental care with the private care providers. Large heterogeneity in patients' preferences was detected. Understanding their preferences may improve the delivery of dental care. Dental care providers should pay particular attention to providing a detailed treatment explanation to their patients. Dental care for older and/or more educated patients should be more attentive to interpersonal characteristics. Faculty dental care provided by faculty members could be price competitive to private care, and student

Strategies to manage patients with dental anxiety and dental phobia: literature review

Directory of Open Access Journals (Sweden)

Appukuttan DP

2016-03-01

Full Text Available Deva Priya Appukuttan Department of Periodontics, Sri Ramakrishna Mission Dental College and Hospital, Chennai, India Abstract: Dental anxiety and phobia result in avoidance of dental care. It is a frequently encountered problem in dental offices. Formulating acceptable evidence-based therapies for such patients is essential, or else they can be a considerable source of stress for the dentist. These patients need to be identified at the earliest opportunity and their concerns addressed. The initial interaction between the dentist and the patient can reveal the presence of anxiety, fear, and phobia. In such situations, subjective evaluation by interviews and self-reporting on fear and anxiety scales and objective assessment of blood pressure, pulse rate, pulse oximetry, finger temperature, and galvanic skin response can greatly enhance the diagnosis and enable categorization of these individuals as mildly, moderately, or highly anxious or dental phobics. Broadly, dental anxiety can be managed by psychotherapeutic interventions, pharmacological interventions, or a combination of both, depending on the level of dental anxiety, patient characteristics, and clinical situations. Psychotherapeutic interventions are either behaviorally or cognitively oriented. Pharmacologically, these patients can be managed using either sedation or general anesthesia. Behavior-modification therapies aim to change unacceptable behaviors through learning, and involve muscle relaxation and relaxation breathing, along with guided imagery and physiological monitoring using biofeedback, hypnosis, acupuncture, distraction, positive reinforcement, stop-signaling, and exposure-based treatments, such as systematic desensitization, “tell-show-do”, and modeling. Cognitive strategies aim to alter and restructure the content of negative cognitions and enhance control over the negative thoughts. Cognitive behavior therapy is a combination of behavior therapy and cognitive therapy

Clinical use of dental classification.

Science.gov (United States)

Jones, Gordon

2008-01-01

The Dental Classification system used by the uniformed services is supposed to predict the incidence of dental emergencies in the operational setting, at least on the unit level. Since most Sailors and Marines are deployed without close dental support, the sea services have adopted a policy of early treatment of class 3 dental conditions during recruit training. The other services are beginning to do the same. Recently, two factors have emerged that are affecting this early dental class 3 treatment. These factors must be considered when planning to provide early dental treatment. First, changing population and dentist provider demographics in the civilian sector are beginning to affect the class 3 treatment needs of incoming military recruits. Second, attrition from recruit training results in treatment provided to recruits who leave military service before finishing their training. Some view this as a waste of resources, others as a cost of doing business. As operational jointness increases, the three services must develop and use a single dental classification terminology, as well as unified standards and guidelines, both for better research in this area and for the readiness and well-being of our patients.

Oral Health, Dental Insurance and Dental Service use in Australia.

Srivastava, Preety; Chen, Gang; Harris, Anthony

2017-01-01

This study uses data from the 2004-2006 Australian National Survey of Adult Oral Health and a simultaneous equation framework to investigate the interrelationships between dental health, private dental insurance and the use of dental services. The results show that insurance participation is influenced by social and demographic factors, health and health behaviours. In turn, these factors affect the use of dental services, both directly and through insurance participation. Our findings confirm that affordability is a major barrier to visiting the dentist for oral health maintenance and treatment. Our results suggest that having supplementary insurance is associated with some 56 percentage points higher probability of seeing the dentist in the general population. For those who did not have private insurance cover, we predict that conditional on them facing the same insurance conditions, on average, having insurance would increase their visits to the dentist by 43 percentage points. The uninsured in the survey have lower income, worse oral health and lower rates of preventive and treatment visits. Copyright © 2015 John Wiley & Sons, Ltd. Copyright © 2015 John Wiley & Sons, Ltd.

2013-01-01

Oral health has a significant impact on the quality of life, appearance, and self-esteem of the people. Preventive dental visits help in the early detection and treatment of oral diseases. Dental care utilization can be defined as the percentage of the population who access dental services over a specified period of time. There are reports that dental patients only visit the dentist when in pain and never bother to return for follow-up in most cases. To improve oral health outcomes an adequate knowledge of the way the individuals use health services and the factors predictive of this behavior is essential. The interest in developing models explaining the utilization of dental services has increased; issues like dental anxiety, price, income, the distance a person had to travel to get care, and preference for preservation of teeth are treated as barriers in regular dental care. Published materials which pertain to the use of dental services by Indian population have been reviewed and analyzed in depth in the present study. Dental surgeons and dental health workers have to play an adequate role in facilitating public enlightenment that people may appreciate the need for regular dental care and make adequate and proper use of the available dental care facilities.

The aim of this study is to assess the dental esthetics awareness among dental students in a private university in Chennai as none is available in Chennai, Tamil Nadu. The dental esthetics awareness questionnaire consisting of a battery of 19 questions under five aspects that is, physical, functional, social, knowledge, and psychological aspects was administered to a sample of 100 dental college students aged between 18 and 27 years in a private college in Chennai, India. Gender variations on the responses of their effects and the impact on dental esthetics awareness had been analyzed using a Chi-square test. With respect to physical aspects, pigmentation shows more significance as students want to get treated for their pigmentation of lips and gums. With respect to functional aspects, eating shows more significance as students have difficulty while eating. In social aspects, habits show more significance as it affects their esthetics. With respect to psychological aspects, mental depression shows more significance as students feel more deprived due to their unesthetic appearance. This study shows a high level of self-consciousness and the findings of the studies prove that even the slightest of variations have a greater impact on the above-mentioned dimensions in particular to psychological, functional, and physical aspects.

Aim: To study the awareness, attitude, practice and facilities among the different categories of dental laboratories in Abha city. Materials and Methods: A total of 80 dental technicians were surveyed in the study. The dental laboratories included in the study were teaching institute (Group I), Government Hospital (Group II), Private Dental Clinic (Group III) and Independent laboratory (Group IV). The pre-tested anonymous questionnaire was used to understand knowledge, attitude, facilities, practice and orientation regarding biomedical waste management. Results: The knowledge of biomedical waste categories, colour coding and segregation was better among Group I (55-65%) and Group II (65-75%). The lowest standard of waste disposal was practiced at Group IV (15-20%) and Group III (25-35%). The availability of disposal facilities was poor at Group IV. The continuous education on biomedical waste management lacked in all the Groups. Conclusion: The significant improvement in disposal facilities was required at Group III and Group IV laboratories. All dental technicians were in need of regular training of biomedical waste management. Clinical Significance: The dental laboratories are an integral part of dental practice. The dental laboratories are actively involved in the generation, handling and disposal of biomedical waste. Hence, it is important to assess the biomedical waste management knowledge, attitude, facilities and practice among different categories of dental laboratories. PMID:26962373

Dental computer assisted tomography (Dental CT) represents a valuable addition to the diagnostic spectrum for planning oral and maxillofacial surgery. High resolution CT and specially designed computer software allow representation of the jaws in different planes that are easy to match. They further allow the display of very small structures relevant to oral surgical interventions and reveal their spatial relationship in three dimensions. Thus, communication between dentists and radiologists may be intensified and supported by usage of modern telecommunication systems. Dental CT is indicated, when clinical and conventional radiological techniques will not allow exact interpretation of the situation. It is modern oral implantology that primarily benefits from computer software enabling the assessment of surgical sites in the presurgical phase. Such planning was not yet possible using two dimensional radiographic techniques. The dental-implantological part expects from radiography sharply defined contours of the external bony contours and the mandibular canal, exactly defined relation between slices and planes, no distortion in the orthoradial planes, tools for reliable measurements of distances, angles and volumes, possibility to transmit pictures electronically or on hardcopy without loss of quality.

Most used dental implants for human dental prostheses are of two steps type: first step means implantation and, after several months healing and osseointegration, second step is prosthesis fixture. For sure, dental implants and prostheses are meant to last for a lifetime. Still, there are unfortunate cases when dental implants break. This paper studies two steps dental implants breakage and proposes a set of instruments for replacement and restoration of the broken implant. First part of the paper sets the input data of the study: structure of the studied two steps dental implants based on two Romanian patents and values of the loading forces found in practice and specialty papers. In the second part of the paper, using DEFORM 2D™ FEM simulation software, worst case scenarios of loading dental implants are studied in order to determine which zones and components of the dental implant set are affected (broken). Last part of the paper is dedicated to design and presentation of a set for extracting and cutting tools used to restore the broken implant set.

Radiographic signs and diagnosis of dental disease

Dental radiographs are critical for the complete assessment and treatment of dental diseases. Dental radiography is commonly used to evaluate congenital dental defects, periodontal disease, orthodontic manipulations, oral tumors, endodontic treatments, oral trauma, and any situation where an abnormality is suspected. Although standard radiographic equipment and film can be used to produce dental radiographs, dental X-ray equipment and film provide superior quality images and greater convenience of animal patient positioning. An understanding of normal dental radiographic anatomy is important when interpreting dental radiographs. Stage III periodontitis is the earliest stage of periodontal disease at which radiographic abnormalities become apparent. Bone loss associated with periodontal disease can be classified as either horizontal or vertical. Periapical radiolucencies can represent granulomas, cysts, or abscesses, whereas periapical radiodensities may represent sclerotic bone or condensing osteitis. Lytic lesions of the bone of the jaw often represent oral neoplasms. Neoplasms also can displace or disrupt teeth in the dental arch. Resorptive lesions can be external or internal and appear as radiolucent areas involving the external surface of the root or the pulp cavity, respectively. Feline dental resorptive lesions, also known as odontoclastic resorptions, are a specific form of dental resorptive lesions unique to cats

The increasing complexity of the dental office environment influences productivity and workflow for dental clinicians. Advances in technology, and with it the range of products needed to provide services, have led to sprawl in operatory setups and the potential for awkward postures for dental clinicians during the delivery of oral health services. Although ergonomics often addresses the prevention of musculoskeletal disorders for specific populations of workers, concepts of workflow and productivity are integral to improved practice in work environments. This article provides suggestions for improving workflow and productivity for dental clinicians. The article applies ergonomic principles to dental practice issues such as equipment and supply management, office design, and workflow management. Implications for improved ergonomic processes and future research are explored.

Dental implant has tried at the early stage in 19th century recovering an oral function and esthetics. Technological revolutions in biochemical and new materials have developed on the remarkable change in the dental implants, nowadays we call the three generation therapy for dental implantology. There are many kinds of methods and techniques in dental implants, however a lot of troublesome complication on the process of surgical phase, construction of prothodontics and prognosis of maintenance care. In the proceedings of this symposium, I would like to propose you how to manage the maintenance care for various kind of dental implants through the methodology and case presentations. Tendenay and future for dental implants The current outlook of dental implant has increasing supply and demand not only dentists but also patients. According to Japanese Welfare Ministry's report in 1987, average missing teeth over sixty years old generations are approximately 42% in accordance with NIDR (U.S.A.) research. They are missed on ten over teeth in full 28th teeth dentitions owing to dental caries and periodontal diseases. Generally speaking, latent implant patients are occupied on the same possibility of needs for dental implants both Japan and U.S.A. Management of maintenance care The patients hardly recognized the importance of plaque control for the maintenance care in the intraoral condition after implantation. Dentists and dental staffs must be instruct patients for importance of plaque removal and control, because they already had forgotten the habit of teeth cleaning, especially in the edenturous conditions. 1) Concept of establishment in oral hygiene. Motivation and instruction for patients include very important factors in dental implants as well as in periodontal diseases. Patients who could not achieve on good oral hygiene levels obtained no good results in the long term observations. To establish good oral hygiene are how to control supra plaque surrounding tissues

Full Text Available Background and Design: Oral lichenoid lesions (OLL are contact stomatitis characterized by white reticular or erosive patches, plaque-like lesions that are clinically and histopathologically indistinguishable from oral lichen planus (OLP. Amalgam dental fillings and dental restoration materials are among the etiologic agents. In the present study, it was aimed to evaluate the standard and dental series patch tests in patients with OLL in comparison to a control group and evaluate our results. Materials and Methods: Thirty-three patients with OLL or OLP and 30 healthy control subjects, who had at least one dental restoration material and/or dental filling, were included in the study. Both groups received standard series and dental patch test and the results were evaluated simultaneously. Results: The most frequent allergens in the dental series patch test in the patient group were palladium chloride (n=4; 12.12% and benzoyl peroxide (n=2, 6.06%. Of the 33 patients with OLL; 8 had positive reaction to allergents in the standard patch test series and 8 had positive reaction in the dental patch test series. There was no significant difference in the rate of patch test reaction to the dental and standard series between the groups. Ten patients were advised to have the dental restoration material removed according to the results of the patch tests. The lesions improved in three patients [removal of all amalgam dental fillings (n=1, replacement of all amalgam dental fillings with an alternative filling material (n=1 and replacement of the dental prosthesis (n=1] following the removal or replacement of the dental restoration material. Conclusion: Dental patch test should be performed in patients with OLL and dental restoration material. Dental filling and/or prosthesis should be removed/replaced if there is a reaction against a dental restoration material-related allergen.

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

Special cluster issue on tribocorrosion of dental materials

Tribocorrosion affects all walks of life from oil and gas conversion to biomedical materials. Wear can interact with corrosion to enhance it or impede it; conversely, corrosion can enhance or impede wear. The understanding of the interactions between physical and chemical phenomena has been greatly assisted by electrochemical and microscopic techniques. In dentistry, it is well recognized that erosion due to dissolution (a term physicists use to denote wear) of enamel can result in tooth decay; however, the effects of the oral environment, i.e. pH levels, electrochemical potential and any interactions due to the forces involved in chewing are not well understood. This special cluster issue includes investigations on the fundamentals of wear-corrosion interactions involved in simulated oral environments, including candidate dental implant and veneer materials. The issue commences with a fundamental study of titanium implants and this is followed by an analysis of the behaviour of commonly used temporomandibular devices in a synovial fluid-like environment. The analysis of tribocorrosion mechanisms of Ti6Al4V biomedical alloys in artificial saliva with different pHs is addressed and is followed by a paper on fretting wear, on hydroxyapatite-titanium composites in simulated body fluid, supplemented with protein (bovine serum albumin). The effects of acid treatments on tooth enamel, and as a surface engineering technique for dental implants, are investigated in two further contributions. An analysis of the physiological parameters of intraoral wear is addressed; this is followed by a study of candidate dental materials in common beverages such as tea and coffee with varying acidity and viscosity and the use of wear maps to identify the safety zones for prediction of material degradation in such conditions. Hence, the special cluster issue consists of a range of tribocorrosion contributions involving many aspects of dental tribocorrosion, from analysis of physiological

The reintroduction and development of safe motorized instruments, the increased availability of continuing education, and the understanding and implementation of appropriate procedures allow practitioners to provide better dental care. Veterinarians realize that sedation, analgesia, a full-mouth speculum, and proper instrumentation are necessary to provide these services. Continued instrument design, future research, and new treatment and prophylactic protocols should have a positive impact on the future of equine dental health. New and rediscovered procedures for equilibrating equine occlusion are allowing horses to masticate more efficiently, carry a bit more comfortably, and experience improved performance. The horse, the horse owner, and the veterinary profession all benefit from providing complete equine dental care.

Full Text Available Esthetic and functional rehabilitation of completely edentulous maxillary arch with fixed implant supported prosthesis is a challenging task. Newer technologies such as computer assisted design computer assisted manufacturing (CAD CAM and cone beam conventional tomography play an important role in achieving predictable results. Full mouth porcelain fused to metal (PFM individual crowns on CAD CAM milled titanium framework provides positive esthetic and functional outcome. This is a case report of rehabilitation of partially edentulous maxillary arch patient. Staged rehabilitation of this patient was planned. In the first stage, root canal treatment of key abutment teeth was done, nonsalvageable teeth were removed, and immediate interim overdenture was provided. In the second stage, five Nobel Biocare dental implants were placed. After integration impressions were made, CAD CAM milled titanium bar was fabricated. Individual PFM crowns were made and cemented. This method gives better esthetic compared to acrylic fused to metal hybrid prosthesis with the advantage of retrievability just like screw retained prosthesis. Hence, this technique is good for rehabilitation of patients with high esthetic demands.
