A study into dentists' knowledge of the treatment of traumatic injuries to young permanent incisors

OBJECTIVE: The aims of this study were to evaluate dentists' knowledge of the emergency treatment of traumatic injuries to young permanent incisors, and to investigate barriers to treatment. DESIGN: A closed-ended questionnaire was sent to 1023 general dental practitioners (GDPs) and community dental officers (CDOs) in West/North Yorkshire and Humberside, UK. METHODS: The questionnaire comprised 17 questions. Six questions asked for general information about the participants (i.e. profession, age, gender, year of graduation, training or education on dental trauma, and willingness to provide emergency care), 10 were relevant to the emergency treatment of crown fractures, root fractures, luxation and avulsion injuries, and the last question queried any perceived barriers to treatment. Results. Seven hundred and twenty-four questionnaires were returned, a response rate of 71%, and these indicated that dentists' knowledge of the emergency treatment of dentoalveolar trauma in children was inadequate. The CDOs were significantly more knowledgeable than the GDPs, as were younger and more recently graduated dentists compared with older ones. The GDPs regarded the difficulty of treating children and the inadequate fees of the UK National Health Service as important barriers to treatment. Dentists who attended continuing dental education courses on dental traumatology had a more thorough knowledge than those who did not. CONCLUSION: Overall, the dentists' knowledge of the emergency treatment of dentoalveolar trauma in children was inadequate. Greater emphasis on undergraduate and postgraduate education in this area is indicated.     

Dentists’ knowledge and opinions about oral mucosal lesions

This study aims to identify, compare and analyse the knowledge and opinions of dentists regarding oral mucosal lesions and evaluate the differences between the attitudes of dentists by practice settings. 300 dentists were enrolled in the study. Three groups were formed. The first group included general dental practitioners working in private dental offices; the second group were dentists practising in dental polyclinics; the third group was composed of dentists employed at universities in Istanbul, working in departments except for the department of oral surgery and medicine. A 17-item self constructed questionnaire investigating demographic attributes, dental practice characteristics, oral mucosal lesions (OML) knowledge and respondents’ opinions was completed and all questions were asked by the same author. 85% of the dentists admitted difficulties in diagnosing OML. 62% failed to update their knowledge from the literature, 93% did not undertake biopsies or consult other practitioners. Dentists practising at universities attempted to treat fewer patients with OML (p = 0.0001). The results of this questionnaire conclude that most dentists experience difficulties in diagnosing some OML.     

Answers from dentists, dental hygienists and dental assistants to questions asked by patients concerning preventive dental matters

142 dentists, 21 dental hygienists and 35 dental assistants were asked lo fill in a questionnaire which consisted of 40 questions about preventive dental matters regularly asked by Dutch dental patients. The 40 questions were submitted to experts in the field of preventive dentistry. The experts were in agreement on 26 questions. It was decided to use these questions for analysis. The average percentage of correctly answered questions was: for the dentists 53%, for the dental hygienists 58% and for the dental assistants 37%. The group of 142 dentists was further analyzed. It appears that the knowledge about preventive dental matters increases subsequently with each year of gradual ion. Analysis of the dentists who graduated from Dutch dental schools in their capacity as private practitioner, as faculty member or in the school dental service, revealed that there was no difference in knowledge between these groups. With some reservations the conclusion can be stated that an obvious necessity exists for post-academic courses in preventive dentistry in the groups concerned. Greater uniformity is needed between the views of the experts and the dental professionals who treat patients daily.     

Knowledge of oral health professionals of treatment of avulsed teeth

Abstract –  The management and immediate treatment of an avulsed permanent tooth will determine the long-term survival of the tooth. The aim of this study was to evaluate the knowledge of oral health professionals on the new guidelines for emergency treatment of avulsed teeth. A 12-item questionnaire was distributed among general dentists, specialists, dental hygienists and dental assistants attending Continuing Education courses at the School of Dentistry, University of Southern California, between 2003 and 2004. This study reports only on the general practitioners who comprised 83% of the participants. The results revealed an uneven pattern of knowledge among them regarding the emergency management of an avulsed tooth. Statistically significant associations were related to the participants' previous dental trauma education and their age. In conclusion, there is a need to improve the knowledge of general dentists in the current guidelines for emergency treatment of avulsed teeth.     

Recognition of malocclusion: an education outcomes assessment.

The purpose of this study was to assess the outcome of predoctoral orthodontic dental education in an American dental school. A test was used that measured the clinical abilities of dental students in the diagnosis of malocclusion in children, as well as their didactic abilities in answering select questions from recent national board examinations in orthodontics. The records of 7 children with different types of malocclusion were selected from the practice of a board-certified orthodontist. These cases were presented to dental students who were asked to make diagnoses and recommendations for treatment. The results of the didactic and clinical tests were used to assess the outcome of the predoctoral dental curriculum in imparting orthodontic knowledge to future general dentists. Didactic knowledge increased over the 4 years of dental education. First year students answered 30% of the questions correctly, whereas fourth year students answered 59% correctly. The relationship between clinical diagnostic skills and dental education, however, was not as strong. The fourth year students answered 70% of questions concerning the 7 cases correctly. These results indicate that fourth year dental students demonstrated only slight improvement compared with first year students, who answered 65% of the questions correctly. Thus, this study indicated that orthodontic diagnostic skills, as measured by the clinical test used, did not improve substantially during 4 years of undergraduate dental education.     

Knowledge of general practitioners dentists about the emergency management of dental avulsion in Curitiba, Brazil

Abstract –  The prognosis of traumatized teeth in general and of avulsed teeth in particular depends on prompt and appropriate treatment. Management of traumatic injuries may be a challenge to the non-specialized dentist, as they may occur when dentists are least prepared for it. The objective of this research was to investigate the knowledge of general practitioner dentists about the emergency management of dental avulsion in Curitiba, PR, Brazil. A group of 250 professionals were interviewed. The questions were related to knowledge of how to treat traumatic avulsion of teeth. The results suggest that the level of knowledge on the management of dental avulsion of the general practitioners dentists in Curitiba is adequate.     

Dental fear and knowledge of children treated by certified pediatric dentists and general practitioners

The purpose of this study was to compare knowledge regarding preventive measures and reported dental fear, of children treated by certified pediatric dentists (CPDs) to those treated by general practitioners (GPs). A questionnaire was given to 300 children, 150 were treated by GPs and the others by CPDs. Children treated by CPDs provided more correct answers to questions about prevention of oral disease (p < 0.001). However, the percentage of children that showed good knowledge was small (14%-82%), and the differences between the two groups on the various questions was only 7%-20%. Children treated by CPDs reported more frequently that they were not afraid of dental treatments (75.3% vs. 39.3%), loved their dentists (50% vs. 31.5%) and received prizes (85.3% vs. 32.7%). These findings suggest that CPDs invest more effort in communication and education of their patients concerning preventive dentistry. There is a need to improve these skills of GPs and CPDs.     

Dentists’ Perception of Oral Potentially Malignant Disorders

ObjectivesDentists play a major role in the diagnosis of oral potentially malignant disorders (OPMDs) that may lead to malignancy. Their knowledge on OPMDs and the risk factors associated with malignant disease needs to be sufficient. The aim of this study was to assess the level of knowledge, attitudes, and awareness of OPMDs amongst general dentists and dental specialists working in Saudi Arabia.Material and methodsQuestionnaires were distributed to dentists working in Saudi Arabia. A total of 303 dentists participated in the study. The questionnaire included 20 questions on knowledge, attitudes, and awareness of OPMDs.ResultsThe response rate was 55%. There was no significant difference between general dental practitioners and dental specialists regarding leukoplakia, which is the most common OPMD (P > .05) and in identifying tobacco and alcohol as the main risk factors for malignant transformation of OPMDs into cancer (P > .05). However, there was a significant difference (P < .05) between specialists (75.3%) and general practitioners (52.3%) in the diagnosis of OPMDs. There was a significant difference (P < .05) between specialists (63.5%) and general practitioners (28.0%) in recognising the likelihood of malignant transformation of proliferative verrucous leukoplakia. There was a significant difference between specialists (61.2%) and general practitioners (25.2%, P < .05) in recognising the erosive form or atrophic type of oral lichen planus, considering that it is more likely to undergo malignant transformation.ConclusionsDental specialists have better knowledge and awareness than general dentists regarding OPMDs. Improved continuous education programmes on the risk factors and diagnosis of OPMDs should be organised to train dentists.     

An investigation into dentists' management methods of dental trauma to maxillary permanent incisors in Victoria, Australia

Abstract –  Trauma to anterior teeth in children could become a long-term problem to dental health. To a large extent, the management actions of the dentists involved will determine the clinical outcome and, in turn, these actions will be related to their levels of knowledge. The aim of this study was to investigate dentists' knowledge of managing traumatic injuries to maxillary permanent incisors in children. A self-completion questionnaire containing 19 questions on management methods of treating dental trauma was mailed to 693 dentists in Victoria, Australia. The response rate achieved was 61%. This survey found that some of the respondents had adequate management knowledge for the different types of traumatic injuries, while others did not have the correct information. Approximately half the dentists considered milk as the preferred extraoral storage medium of choice for avulsed teeth and a period of 7–10 days splinting after replantation. A large proportion of dentists showed inadequate knowledge with regard to understanding the biological mechanisms causing replacement root resorption (61%) and external inflammatory root resorption (74%). Overall, the respondents to this survey demonstrated only a moderate level of knowledge in management of traumatic injuries to maxillary permanent incisors in children. Continuing professional development programmes may be a means of improving this deficient knowledge base.     

Knowledge of Brazilian general dentists and endodontists about the emergency management of dento-alveolar trauma

Abstract –  The purpose of this study was to determine Brazilian dentists' knowledge of emergency management of dento-alveolar trauma. A two-part questionnaire containing questions on demographic data and knowledge were mailed to 230 general dental practitioners (GDPs) and 70 endodontists. Questionnaires were returned by 42.6% of the GDPs and 62.8% of the endodontists. The survey data were statistically analyzed using Mann–Whitney U -test for practitioners' knowledge and Pearson's correlation coefficient for association between knowledge scores and practitioner age or years since graduation. The mean knowledge score of endodontists was significantly greater than for GDPs ( P  < 0.0001). Dentists with trauma experience in their practices and those who had attended postgraduate courses on dental trauma had a significant higher mean knowledge score. In contrast, there was a poor correlation between the knowledge score and the ages of the respondents ( r  = 0.086) or the years since graduation ( r  = 0.108). In conclusion, this survey showed a poor knowledge of dental trauma management among the surveyed dentists and highlights the need to develop strategies to improve the knowledge base in this area of dentistry for the benefit of the dental trauma patient.     

What do dentists know about statistics?

Abstract – A multiple choice test with nine statistical questions was sent to a random sample of Danish dentists to assess their knowledge of elementary statistical expressions (SD, SE, P<0.05, P> 0.05 and r). Of 250 dentists, 129 (52%) answered the questions. The test was also completed by 27 (71%) of 38 dental students immediately after the last lecture in statistics. The median number of correct answers was 2.2 among the dentists and 3.4 among the dental students. It is concluded that the statistical knowledge of most dentists, and to a lesser degree also dental students, is so limited that they cannot be expected to be critically against or to draw the right conclusions from those statistical analyses with which they are confronted. Only 35% of the dentists stated that it is very important that this problem be raised.

Knowledge and competence in temporomandibular disorders among Swedish general dental practitioners and dental hygienists

Objective: The aim of this study was to investigate knowledge and competence in temporomandibular disorders (TMD) among dentists and dental hygienists working in the public dental service (PDS) in Sweden.

Materials and methods: The study population comprised all general dentists (n?=?110) and dental hygienists (n?=?80) working in the PDS in two Swedish counties: Kronoberg (K) and Blekinge (B). The participants filled out a questionnaire comprised of 15 questions.

Results: The results of these questions are presented. The overall response rate for the general dentists was 87%, while the rate for the dental hygienists was 71%. Statistically significant differences between the general dentists in the two counties were found regarding the following: education in the field of TMD over the last 5 years (K: 37%, B: 73%), evaluation of occlusion when examining patients with suspected TMD (‘always’: K: 61%, B: 82%), and a desire for consultation of the OFP (orofacial pain)/TMD specialist by telephone (K: 71%, B: 44%). Regarding the dental hygienists, there was a statistically significant difference concerning the use of the treatment modality ‘reassurance’ (K: 41%, B: 7%).

Conclusions: The majority of the dental care providers in both counties – irrespective of professional category – had a positive attitude towards patients with TMD. Knowledge and competence in the field are sparse and require postgraduate education. There is a great need of an OFP/TMD specialist for more complicated patients and a need to implement updated knowledge and competence in the PDS in these two counties.     

Are general dentists' practice patterns and attitudes about treating Medicaid-enrolled preschool age children related to dental school training?

PURPOSE: The purpose of this study were to investigate the willingness of general practitioners to provide dental care for preschool-aged children, and to explore the relationship between dental school experiences and practitioners' attitudes about treating Medicaid-enrolled children 3 years of age and younger. METHODS: A survey was mailed to 3,559 randomly selected general dentists in Texas. Respondents were asked to answer questions about their willingness to provide specified dental procedures for children of different ages, their dental school experiences with pediatric dentistry and whether these experiences were hands-on, lecture or no training, and their attitudes concerning treating Medicaid-enrolled children 3 years of age or younger. Associations between attitudes about treating Medicaid-enrolled children and dental school experiences were determined. RESULTS: The response rate was 26%. Almost all respondents were willing to provide routine procedures such as an examination (95%) and prophylaxis (94%) for children 5 years or younger. However, as children became younger and procedures more difficult, the number of general dentists willing to provide treatment decreased. The level of dental school training was significantly associated with the attitudes of general dentists about providing dental care for Medicaid-enrolled preschool-aged children (P < or = 0.05). CONCLUSION: Identification of factors associated with general dentists' willingness to see young children may improve access by increasing the number who will provide care for preschool-aged children.     

Awareness of dental practitioners to cope with a medical emergency: a survey in Belgium

Objective: The aim of the study is to determine whether in Belgium dentists feel confident to diagnose a medical emergency situation in their dental practice. Methods: A questionnaire was completed by 7.0% of the active Belgian general dental practitioners (n = 548) including questions on the frequency and knowledge of medical emergency situations in the dental office, history of dental training to treat emergency situations and confidence level in treating emergency situations. Results: A medical history of each patient was taken by 55.3% of the dentists. A link was found between years since graduation and the systematic decline of a medical history in a new patient (P = 0.001): the older the dentist, the less consistent was the updating of medical history. Almost 50% of the dentists (49.4%) never participated in any basic life support (BLS) training during their undergraduate education. Moreover, 78.3% never had any paediatric BLS training during undergraduate education and BLS training after graduation was lacking by 37.2% of the dentists. Conclusion: Knowledge of BLS should be fundamental to medical professionals. The more BLS training a practitioner has experienced, the more self-secure they feel coping with an emergency situation.Key words: Basic life support (BLS) training, dentist and medical emergency situations, dentists and medical history     

A longitudinal study into changing ethical attitudes of newly-qualified dentists in South-East England.

OBJECTIVE: To report the ethical stances taken by newly-qualified dental graduates working in the south-east of England and how these changed over their first two years in practice. METHODS: A longitudinal self-completed questionnaire-based study using scenarios and closed questions was completed by an initial group of 135 vocational dental practitioners at the very beginning of their vocational training year, at the end of the year, and, finally, at the end of the subsequent year. Their answers were then analysed to see whether or not their views had changed during this period. RESULTS: At the commencement of the study in 2003, 133 (99%) newly-qualified dental graduates completed the questionnaire and answered the closed questions. The following year, 129 (96%) completed these documents and in 2005, at the end of the study, this figure was 97 (72%). There was considerable variation in the attitudes taken by the responding dentists. Reported attitudes changed over the study period in seven of the nine scenarios. Responses to the scenarios used could be grouped into three categories: those in which there was no change; those in which the change happened following completion of vocational training; and those in which there was a continual change. Answers to the four closed questions indicated a growing negativity to practice within the National Health Service over the study period. CONCLUSIONS: Dental educators need to be aware of the findings from this study. The importance of the ethical attitudes held and the reasons underpinning them should be explored if problems with delivery of care are to be avoided in the future.

Antibiotic prophylaxis for bacterial endocarditis--a study of knowledge and application of guidelines among dentists and cardiologists

Antibiotic prophylaxis and infective endocarditis is a controversial topic. The compliance with available guidelines among dentists is poor. The dental health education of patients by their cardiologists is inadequate. OBJECTIVE: The objective of this study was to investigate the knowledge and application of available guidelines on antibiotic prophylaxis to prevent infective endocarditis among general dental practitioners and cardiologists. DESIGN: Structured postal questionnaire SUBJECTS AND METHODS: A list of 515 dentists was obtained from a register held by the Postgraduate Medical and Dental Board. A list of 85 cardiologists was obtained from a national register held by the Cardiothoracic Society of Ireland. RESULTS: A 31% response rate was obtained from the cardiologists and 37% from the dentists. The majority of the cardiologists (84%) were in hospital practice and 64% of dentists were in private general practice. Cardiologists showed a preference for the AHA guidelines (50%) and more dentists use the BSAC guidelines (56%). The cardiologists were very familiar with the cardiac conditions that pose a risk for dental patients but weak at educating their patients on the importance of good dental health. The dentists were good at identifying procedures that could place their patients at risk but less informed about which cardiac conditions warranted prophylaxis. Decision-making among the dentists with regard to choice of prophylaxis and appropriate treatment intervals was poor. CONCLUSIONS: The knowledge of and compliance with the available guidelines is poor. Dental health education of at-risk patients by their cardiologists and dentists is inadequate. Further regular education of patients, dentists and medical practitioners is required.
