Knowledge, dentist confidence and management of periodontal patients among general dentists from Belarus, Lithuania, Macedonia, Moldova and Romania

BACKGROUND

Evidence concerning periodontal practice in Eastern European countries is scarce. The aim of the present study was to investigate periodontal risk knowledge, patient management and self-perceived confidence among General Dentists (GDs) from five Eastern European regarding their provision of periodontal care.

METHODS

GDs from Belarus, Lithuania, Macedonia, Moldova and Romania participated in a questionnaire survey. Power calculations were used to identify the sample size for each country. The structured questionnaire included several domains of inquiry. The socio-demographic domain inquired about dentist's age, gender and years of clinical experience. The dental practice domain inquired about practice location, practising or not practising in a group practice and having or not having a periodontist or a dental hygienist in the practice. The distributions of answers across-countries were compared employing one way ANOVA (comparison of means) or Chi square test (comparison of proportions). For each country, the predictors of the study outcomes: a summative knowledge score for periodontal risks and dentist's confidence level were identified employing either linear or logistic multiple regression models.

RESULTS

The sample comprised 390 Belarussian, 488 Lithuanian, 349 Macedonian, 316 Moldovan, and 401 Romanian GDs. The majority of GDs (~ 80%) practiced in urban areas. Age and gender distributions differed significantly among countries. Significant across-country differences were found regarding working/not working in a group practice, having/not having access to a periodontist/dental hygienist and in proportions of patients receiving periodontal treatments or being referred to specialists. None of Macedonian patients nor the majority of Moldovan patients (78%) were referred to periodontists. There were also significant across-country differences in diagnosis, patient management and periodontal knowledge. Only in the Lithuanian cohort were dentists' confidence levels associated significantly with their knowledge. In all countries, taking a medical history was a consistent and significant predictor of having higher periodontal knowledge score. Except in Belarus, periodontal risk assessment was a significantly consistent predictor of certainty levels associated with the provision of periodontal treatments.

CONCLUSIONS

There were substantial differences among GDs in the five countries regarding diagnosis, dentist's confidence and management of periodontal patients.

The Spectrum of Histological Findings in Oral Biopsies

Aim: To undertake a retrospective analysis of the use of a diagnostic pathology service, to determine the source of oral biopsies submitted for histological analysis, and to examine the range and frequencies of histologically diagnosed oral lesions in an Irish population. Methods: A retrospective analysis was carried out on all oral biopsies submitted for histological analysis to an oral and maxillofacial diagnostic pathology service from June to December 2015. Results: In total 724 oral biopsies were submitted. The majority of diagnoses were benign (80.3%) and the remaining diagnoses were made up of malignancies (6.7%) and potentially malignant disorders (PMDs), histologically characterised by epithelial dysplasia (13%). Less than 1% of biopsies were submitted from general dentists in primary care. Conclusion: This study showed that oral biopsies are not submitted from the primary care setting, but rather from hospital-based specialist units or referral-based specialist practitioners. There was a broad range of histological diagnoses, the majority of which were benign.

Utilization of Stainless Steel Crowns by Pediatric and General Dentists

Purpose: Dental caries affects 23 percent of U.S. children aged two to five years old. 1 Stainless steel crowns (SSCs) are used for extensive caries and offer greater longevity than other restorations; however, disparity exists between pediatric and general dentists in restoration type provided. The purpose of this study was to evaluate utilization of stainless steel crowns among pediatric and general dentists by reviewing insurance claims. Methods: Data were obtained from a commercial dental insurance claims data warehouse from more than 50 dental insurance plans and multiple carriers in the United States for children 12 years old and younger. Data were examined for treatment of the primary dentition using SSCs or direct restorations. A generalized linear mixed effects model tested differences in the utilization of SSCs by general dentists (GDs) versus pediatric dentists (PD). Results: The data included 107,487 GDs and 5,395 PDs. The records included 2,555,726 claims for direct restorations and 440,423 claims for SSCs. PDs are more likely to place SSCs compared to GDs (odds ratio equals 3.2; P<0.0001). Conclusions: Pediatric dentists are more likely to restore carious primary dentitions with stainless steel crowns than general dentists. Perhaps increased training at the dental undergraduate level and access to more continuing education courses for general dentists would increase the utilization of SSCs.

A systems approach using the functional resonance analysis method to support fluoride varnish application for children attending general dental practice

BACKGROUND

All children attending General Dental Practice in Scotland are recommended to receive twice-yearly applications of sodium fluoride varnish to prevent childhood caries, yet application is variable. Development of complex interventions requires theorizing and modelling to understand context. This study applies the Functional Resonance Analysis Method (FRAM) to produce a sociotechnical systems model and identify opportunities for intervention to support application.

METHODS

The FRAM was used to synthesise data which were: routine monitoring of fluoride varnish application in 2015/16; a longitudinal survey with practitioners (n = 1090); in-depth practitioner and key informant interviews (n = 43); and a 'world café' workshop (n = 56).

RESULTS

We describe a detailed model of functions linked to application, and use this to make recommendations for system-wide intervention.

CONCLUSIONS

Rigorous research is required to produce accessible models of complex systems in healthcare. This novel paper shows how careful articulation of the functions associated with fluoride varnish application can support future improvement efforts.

Understanding continuous professional development participation and choice of mid-career general dental practitioners

OBJECTIVE

Participating in continuing professional development (CPD) activities is a requirement for dental practitioners to keep their skills and knowledge up to date. Understanding the ways dental practitioners engage with professional development and the impact on practice is not fully known (Eaton et al. 2011, http://www.gdc-uk.org/Aboutus/policy/Documents/Impact%20Of%20CPD%20In%20Dentistry.pdf). The aim of this study was to gain insights into the ways that dentists reflect on their professional development and what may be influencing their choices.

METHOD

Empirical qualitative data were collected by semi-structured interviewing of five mid-career dentists. Using grounded theory, the data were analysed for themes about CPD choice and participation.

RESULTS

Three themes were identified as influences to dentists' choices of CPD with pragmatic considerations of how new learning could benefit their patients and their practices. Dental practitioners were influenced by the requirements of external regulatory bodies which they did not consider to necessarily improve practice.

CONCLUSION

Dentists working in primary care in the UK are undertaking CPD which is influenced by the pragmatic requirements of running a small business and to meet regulatory requirements. In this sample, dentists are not critically reflecting on their education needs when choosing their CPD activity. Protected learning time and organisational feedback and support are recommended as a way to promote more meaningful reflection on learning and to improve professional development.

Provision of Specific Dental Procedures By General Dentists in the National Dental Practice-Based Research Network: Questionnaire Findings

BACKGROUND

Objectives were to: (1) determine whether and how often general dentists (GDs) provide specific dental procedures; and (2) test the hypothesis that provision is associated with key dentist, practice, and patient characteristics.

METHODS

GDs (n = 2,367) in the United States National Dental Practice-Based Research Network completed an Enrollment Questionnaire that included: (1) dentist; (2) practice; and (3) patient characteristics, and how commonly they provide each of 10 dental procedures. We determined how commonly procedures were provided and tested the hypothesis that provision was substantively related to the 3 sets of characteristics.

RESULTS

Two procedure categories were classified as "uncommon" (orthodontics, periodontal surgery), 3 were "common" (molar endodontics; implants; non-surgical periodontics), and 5 were "very common" (restorative; esthetic procedures; extractions; removable prosthetics; non-molar endodontics). Dentist, practice, and patient characteristics were substantively related to procedure provision; several characteristics seemed to have pervasive effects, such as dentist gender, training after dental school, full-time/part- time status, private practice vs. institutional practice, presence of a specialist in the same practice, and insurance status of patients.

CONCLUSIONS

As a group, GDs provide a comprehensive range of procedures. However, provision by individual dentists is substantively related to certain dentist, practice, and patient characteristics. A large number and broad range of factors seem to influence which procedures GDs provide. This may have implications for how GDs respond to the ever-changing landscape of dental care utilization, patient population demography, scope of practice, delivery models and GDs' evolving role in primary care.

Dental service provision by oral health therapists, dental hygienists and dental therapists in Australia: implications for workforce modelling

OBJECTIVE

Dental service provision rates are necessary for workforce planning. This study estimates patient and service rates for oral health therapists (OHTs), dental hygienists (DHs) and dental therapists (DTs). To identify important variables for workforce modelling, variations in rates by practice characteristics were assessed.

DESIGN

A cross-sectional self-complete mailed questionnaire collected demographic and employment characteristics, and clinical activity on a self-selected typical day of practice.

SETTING

Private and public dental practices in Australia.

PARTICIPANTS

Members of the two professional associations representing DHs, DTs and OHTs.

METHODS

For each practitioner type, means and adjusted rate ratios of patients per hour, services per visit and preventive services per visit were estimated. Comparisons by practice characteristics were assessed by negative binomial regression models.

RESULTS

Response rate was 60.6% (n = 1,083), 90.9% were employed of which 86.3% were working in clinical practice and completed the service log. Mean services per patient visit provided by OHTs, DHs and DTs were 3.7, 3.5 and 3.3 and mean preventive services per patient were 2.1, 2.1 and 1.8 respectively. For all three groups, adjusting for explanatory variables, the rate of preventive services per patient varied significantly by practice type (general or specialist) and by the proportion of child patients treated.

CONCLUSION

Services rates varied by age distribution of patients and type of practice. If these factors were anticipated to vary over-time, then workforce planning models should consider accounting for the potential impact on capacity to supply services by these dental workforce groups.

A review of daycase GA services for Special Care patients at University Hospital, Bristol

This paper describes and discusses a review of adult special care dentistry day cases in a UK hospital over a two year period and makes recommendations for other such reviews and for practice. Dental public health competencies illustrated: oral health needs assessment and evaluation of dental health services.

Mapping the Quebec dental workforce: ranking rural oral health disparities

INTRODUCTION

Ensuring access to oral health services is crucial for improving the oral health of rural and remote populations. A logical step towards addressing oral health disparities and underutilization of services in rural areas is to ensure the availability of the dental workforce. Geographical information systems are valuable in examining workforce dispersion patterns and identifying priority areas requiring administrative and policy attention. The objective of this study was to examine and map the distribution patterns of the dental workforce in Quebec, Canada.

METHODS

Utilizing the membership directory of Quebec Professional Orders (2009-2010), data on practice locations, practice types and license issue date for all active members of the Quebec dental workforce were obtained. This was followed by reverse geocoding of the geographic coordinates using a global positioning system visualizer to reveal textual locations. These locations were classified according to various degrees of rurality as defined by the 2006 Census Metropolitan Area and Census Agglomeration Influenced Zone typology, developed by Statistics Canada. Cartography layers were extracted from a geospatial database provided by Canada Natural Resources using ArcGIS 9.3. Descriptive and bivariate analyses were performed using SPSS v17 for Windows.

RESULTS

Data analysis revealed statistically significant differences in the distribution of dental professionals in rural and urban areas (urban 59.4±19.4/100 000 vs rural 39.9±17.6/100 000; p<0.001). Approximately 90.3% of the dental workforce was located in urban zones, 1.3% in the zones strongly influenced by metropolitan area, 4.9% in the moderately influenced zones, while only 0.3% of the dental workforce was located in non-metropolitan-influenced zones. Urban zones such as Montreal, Quebec and Sherbrooke had the highest workforce availability (4-6 dentists for every 5000 inhabitants). Of a total of 447 specialist dentists in Quebec, only five were located in rural areas.

CONCLUSIONS

This study concludes that there is a strong relationship between the degree of urbanization and the highest concentration of dental professionals. In addition, there is a lack of dental workforce availability, particularly specialists in rural Quebec. Further research is needed to examine and evaluate to what degree these distribution patterns might contribute to oral health outcomes of the rural population.

Prospective study on dental extractions carried out for paediatric patients under general anaesthetic in a district general hospital

BACKGROUND

The first line approach to managing healthy anxious children requiring dental extractions should include behavioural management and treatment under local anaesthetic. This can be coupled with conscious sedation.

AIM

To evaluate alternative methods attempted prior to treatment under general anaesthesia (GA), to establish the incidence of repeat GA procedures.

METHOD

Paediatric cases requiring dental extractions under GA were audited from October 2014 - December 2014 in the Oral and Maxillofacial Department, Great Western Hospital, Swindon.

RESULTS

78 paediatric cases requiring dental extractions were carried out during the study period. 91% of referrals came from local general dental practitioners (GDPs). The indication for the GA was included in 59% of the referral letters. The number of teeth extracted per case ranged from 1 - 14. In 18% of cases treatment under local anaesthetic had been attempted previously. Conscious sedation had not been attempted in any of the cases. There were 5 cases (6.4%) of repeat general anaesthetic procedures.

CONCLUSION

Local guidance regarding appropriate paediatric referrals should be distributed to primary care referrers. Treatment under conscious sedation should be considered for paediatric cases and an improved referral pathway to the community dental service should be developed. Preventative advice should be reinforced to the referrer and to the patient.

Perception of dental practitioners regarding the use of antioxidants in oral health

BACKGROUND

Free radicals play a key role in the development of several pathological conditions. Therefore, antioxidants (AOs) are the first line of defense against free radical damage and are critical for maintaining optimum health and well-being.

OBJECTIVES

To assess the perception of dental practitioners regarding use of antioxidants in oral health.

METHOD

A cross-sectional questionnaire study was conducted among 296 dental practitioners in Tricity (Chandigarh, Mohali, Panchkula, India). A self-structured close-ended questionnaire was used to assess the perception of dentists regarding the use of antioxidants in their patients. It consisted of 12 questions with dichotomous response and five point likert scale ranging from strongly agree to strongly disagree. Descriptive statistics were used to summarize the data, followed by the Chi-square test to check significant differences between the responses. Correlation between responses were analysed through the Spearman's rank correlation. Statistical analysis was done using Statistical Package for Social Sciences version 20 (Illinois, Chicago, USA).

RESULTS

A statistically significant difference was observed between genders, with females 181 (61%) having more knowledge than males 115 (39%) regarding the use of antioxidants in their clinical practice. It has been found that dental professionals in academics prescribes more antioxidants to their patients than the private practitioners. Postgraduates 76 (77.6%) had a higher level of knowledge than graduates 86 (43%).

CONCLUSIONS

Knowledge about antioxidants should be highlighted in the health sciences curriculum. It is recommended to expand the use of antioxidants in oral health to bring down the burden of chronic diseases like periodontitis and catastrophic diseases like precancerous lesions and oral cancer.

KEY WORDS

antioxidants, free radicals, mouth neoplasms, oral health.

General Dentists' Use of Isolation Techniques during Root Canal Treatment: From the National Dental Practice-based Research Network

INTRODUCTION

A preliminary study done by a National Dental Practice-Based Research Network precursor observed that 44% of general dentists (GDs) reported always using a rubber dam (RD) during root canal treatment (RCT). This full-scale study quantified the use of all isolation techniques, including RD use.

METHODS

Network practitioners completed a questionnaire about isolation techniques used during RCT. Network enrollment questionnaire data provided practitioner characteristics.

RESULTS

One thousand four hundred ninety of 1716 eligible GDs participated (87%); 697 (47%) reported always using an RD. This percentage varied by tooth type. These GDs were more likely to always use an RD, do not own a private practice, perform less than 10 RCTs/month, and have postgraduate training.

CONCLUSIONS

Most GDs do not use an RD all the time. Ironically, RDs are used more frequently by GDs who do not perform molar RCT. RD use varies with tooth type and certain dentist, practice, and patient characteristics.

Learning from a Special Care Dentistry Needs Assessment

The General Dental Council recognised special care dentistry (SCD) as a speciality in 2008 and local service reviews have been carried out in order to develop SCD services. A needs assessment was completed to inform the implementation of recommendations from a 2010 review of SCD in Wales.

AIM

The aim of this paper is to outline the process, findings and learning from the needs assessment and the implications for SCD.

METHOD

A focused needs assessment approach was used. Stakeholder consultations were used to develop a working definition for the needs assessment. Data were collected from existing health and social care sources and analysed using descriptives and geographic information system (GIS) mapping.

RESULTS

Data sources for needs assessment were limited. Analysis showed that health conditions were common in the population and increased with age. The majority of people who reported seeing a dentist were seen in general dental practice. Older people with health conditions were less likely to report seeing a dentist. Patients often needed to travel for specialist care services.

CONCLUSION

General dental practice teams have a significant role in caring for SCD patients. Careful planning of specialist care, joint working and enhancing skills across the general practice team will reduce the burden of care and enhance patient safety. Improvements in data for assessment of SCD needs are required to help this process.

Dental school vacant budgeted faculty positions, academic years 2008-09 to 2010-11

The annual turnover of dental school faculty creates a varying number of vacant budgeted positions from year to year. The American Dental Education Association (ADEA) conducts an annual survey to determine the status and characteristics of these vacant faculty positions. The number of vacant budgeted faculty positions in U.S. dental schools increased throughout the 1990s, with a peak of 417 positions in 2005-06. Since that time, there has been a decrease in the number of estimated vacancies, falling to 227 in 2010-11. The 2008-09 to 2010-11 faculty vacancy surveys explored these decreases, along with information relevant to the number and characteristics of dental faculty vacancies, including data on the distribution of full-time, part-time, and volunteer faculty, reasons for faculty separations, and sources of new faculty.

[Dentistry and healthcare legislation 10. The law governing complaints: readily accessible filing procedures]

The law promises patients a readily accessible means of filing complaints. Healthcare providers are therefore required to adopt regulations governing complaints which satisfy a number of conditions. Most dentists choose to adopt the regulations which have been established by their professional organization. In addition to handling complaints, there is also a provision for mediation, which is often used by patients. Mediation appears, then, to be a successful provision. Many complaints have their origin in insufficient knowledge of healthcare legislation and patients' rights legislation. This demonstrates that more attention should be given to these subjects in educational programmes and programmes in continuing education. The present law governing complaints is expected to be replaced this year by a new, more comprehensive law in which considerable attention will be devoted to the quality of care as well as to complaints. It seems likely, however, that the new law governing complaints will damage the effective manner in which patients' complaints are dealt with in dentistry today.

An assessment of career satisfaction among Macedonian dentists

AIM

The aim of this study was to assess the level of overall career satisfaction in relation to various personal and work-related factors among the dentists in the Republic of Macedonia.

MATERIALS AND METHODS

The sample comprised 118 registered dentists, working in different conditions (34 public practice dentists, 32 completely private, 42 private dentists who work with a health insurance fund and 10 concessioners). All of them filled in a questionnaire which contained 16 items, divided into five groups. The different clusters of questions were related to various working conditions and personal factors. The first four groups of questions were answered with a--point Likert format with a score range from 1 (very dissatisfied) to 4 (very satisfied). In the fifth group, dentists chose one of four offered answers. The statistical analyses were made by one-way ANOVA and chi-square tests.

RESULTS

Significant differences related to working conditions were found between public practitioners (moderately dissatisfied) and private practitioners (very satisfied) (F=41.41 (df=3); p<0.01). A high prevalence of dentists (89.83%) had felt stressed on their work place and 61.8% of public dental health practitioners had felt stressed at work "very often". The main sources of job-related stress for public dental practitioners were their supervisors (50%) and patients (26. 47%), while private practitioners were mostly stressed by inspectors (76.19%) and patients (21.87%) (χ2=44.5 (df=9); p<0.01).

CONCLUSION

The findings in our study showed overall low levels of career satisfaction among the dentists (public and private) in the Republic of Macedonia. The finding that high percentages of dentists feel stress at their work place very often requires further exploration.

Outcome of orthodontic care and residual treatment need in Swedish 19-year-olds

The purpose of the study was to assess the outcome of orthodontic care in Linköping, Sweden. The dental records of 207 (107 M, 100 F) 19-year-olds registered at one public dental health clinic were studied. A clinical examination was performed where malocclu- sions were registered, where after residual orthodontictreatment need was measured using the Index of Complexity, Outcome and Need (ICON). The 19-year-olds also filled in a questionnaire regarding residual subjective orthodontic treatment demand. Differences between genders were analysed. One hundred and ten (47 M, 63 F) individuals (53.1%) had partaken in orthodontic consultations. Orthodontic appliance treatment had been received by 86 (38 M, 48 F) individuals (41.6%). A residual orthodontic treatment need was registered in 28 (22 M, 6 F) individuals (13.5%). Residual subjective orthodontic treatment demand was expressed by 9 (3 M, 6 F) indi- viduals (4.3%). Eight (2 M, 6 F) of those had no residual treatment need. A higher (p = 0.006) rate of females (63.0%) than males (44.0%) had participated in ort- hodontic consultations. The proportion of males (35.5%) who had experienced orthodontic treatment was not significantly lower (p = 0.069) than among the females (48.0%). However, a lower (p = 0.009) proportion of treated males (55.3%; n = 21 out of 38) than of treated females (81.3%; n = 39 out of 48) had received their treatment by orthodontic specialists. At 19 years of age, the proportion of males with residual treatment need (20.6%) was higher (p = 0.002) than among the females (6.0%). Every patient with orthodontic treatment need and -demand at 19 years of age had previously been offered orthodontic treatment. The conclusion was drawn that the orthodontic care scheme had successfully diagnosed and treated orthodontic problems in the population. However, notable differences between genders regarding treatment modalities and the amount of residual treatment need at age 19 were found.

Dental radiography in New Zealand: digital versus film

Digital x-ray systems offer advantages over conventional film systems, yet many dentists have not adopted digital technology.

OBJECTIVES

To assess New Zealand dental practitioners' use of--and preferences for--dental radiography systems.

DESIGN

Cross-sectional survey.

SETTING

General and specialist dental practice.

PARTICIPANTS AND METHODS

Postal questionnaire survey of a sample of 770 dentists (520 randomly selected general dental practitioners and all 250 specialists) listed in the 2012 NZ Dental Council Register.

MAIN OUTCOME MEASURES

Type of radiography systems used by dentists. Dentists' experiences and opinions of conventional film and digital radiography.

RESULTS

The participation rate was 55.2%. Digital radiography systems were used by 58.0% of participating dentists, most commonly among those aged 31-40 years. Users of digital radiography tended to report greater satisfaction with their radiography systems than users conventional films. Two-thirds of film users were interested in switching to digital radiography in the near future. Reasons given by conventional film users for not using digital radiography included cost, difficulty in integrating with other software systems, concern about potential technical errors, and the size and nature of the intra-oral sensors.

CONCLUSION

Many dental practitioners have still not adopted digital radiography, yet its users are more satisfied with their radiography systems than are conventional film users. The latter may find changing to a digital system to be satisfying and rewarding.

An analysis of the attitudes of dental patients attending general dental practice in Galway

AIM

To describe the patterns of dental attendance and attitudes towards tooth loss of general dental practice patients in Galway.

OBJECTIVES

1. To determine the pattern of adult dental attendance in general practices in Galway; and, 2. To examine the oral health attitudes of these patients.

METHOD

Questionnaires were distributed to 311 consecutive adult patients in the waiting rooms of ten general dental practices in Galway, which were randomly selected from the telephone directory.

RESULTS

A total of 254 of the 311 questionnaires distributed were fully completed, returned and included in the results, giving a response rate of 81.7%. A total of 59% of dentate participants attended their dentist for annual or biannual examinations compared to 23% of edentate patients. Some 10.5% of medical card holders and 0.5% of non-medical card holders were edentulous.

CONCLUSIONS

The data from the survey indicated that medical card holders in Galway were more likely to be edentulous than nonmedical card holders. Edentate patients were less likely to be regular dental attenders than dentate patients.

Finishing and polishing procedures of composite restorations by Saudi dentists: a cross-sectional study

AIM

The purpose of this study was to assess the knowledge and practices of Saudi dentists in finishing and polishing composite restorations.

MATERIALS AND METHODS

A cross-sectional questionnaire-based study was conducted among 306 Saudi dentists from March to April 2012. The collected data were analyzed using Microsoft Excel 2010 program and descriptive statistics were obtained.

RESULTS

Completed questionnaires were returned by 191 participants, giving a response rate of 62.4%. 115 (65.7%) respondents are using fine diamond finishing burs for finishing occlusal surfaces, 82 (48%) used fine aluminum oxide finishing discs for finishing facial surfaces, 130 (76%) used diamond finishing strips for finishing interproximal surfaces.121 (63.4%) respondents were of the view that the type of filler content has a major influence in providing color stability to the composite restoration and 137 (72.1%) believed nano-composites provided enhanced color stability.

CONCLUSION

Dentists in Saudi Arabia are aware of the benefits of proper finishing and polishing of composite restorations. They however need to use finishing and polishing burs, disks, strips and pastes in a sequential series. Usage of composite polishing pastes and composite surface sealants should be emphasized in undergraduate curriculum.

New Zealand dentists' views on community water fluoridation

OBJECTIVE

To determine whether New Zealand general dental practitioners support community water fluoridation (CWF), and to gauge their opinions on its possible systemic side-effects.

METHODS

An online survey was conducted in 2010, involving the 1174 general dental practitioners who had email addresses on the Dental Register and were contactable in New Zealand. A total of 465 dentists (39.6%) participated.

RESULTS

Most practitioners (93.5%) reported supporting community water fluoridation; the other 6.5% either were unsure or did not support it. Higher proportions of more recent graduates supported CWF. Some 85.6% of practitioners thought that drinking fluoridated water was a harmless way to prevent dental caries, but 6.2% felt that fluoridated water may cause other health problems. There were no systematic differences by sociodemographic and practice characteristics, except that a higher proportion of males and more experienced practitioners reported being confident in discussing CWF-related issues.

CONCLUSIONS

Most New Zealand dental practitioners support community water fluoridation, although a very small proportion believe that it is harmful and/or does not prevent caries.

Ergonomics and musculoskeletal disorder: as an occupational hazard in dentistry

OBJECTIVE

Musculoskeletal disorders (MSDs) are commonly experienced in dentistry. The objective of this study is to determine the prevalence of ergonomics and MSDs among dental professionals.

MATERIALS AND METHODS

A cross-sectional survey was conducted among 170 dentists of different specialties. The questionnaire gathered information regarding demographic details, MSDs, work duration, working status, awareness of ergonomics, etc. Data was analyzed using SPSS version 15.0. Student's t-test and analysis of variance (ANOVA) test was used for comparison in mean scores. Stepwise multiple linear regression analysis was used to assess the independent variables that significantly influenced the variance in the dependent variable (pain).

RESULTS

It was found that 73.9% of the participants reported musculoskeletal pain and most common painful sites were neck and back. More than half of the participants, i.e. 232 (59.3%) were aware of correct ergonomic posture regarding dental. Almost percentage of pain increased significantly with increase in age and working time. Among all specialties, prosthodontics were found to have more prevalence of MSDs.

CLINICAL SIGNIFICANCE

The appearance of musculoskeletal symptoms among dental professionals was quite common. It suggested that ergonomics should be covered in the educational system to reduce risks to dental practitioners.

Reasons for extraction of permanent teeth in general dental practices in Tehran, Iran

OBJECTIVES

The aim of this survey was to investigate the primary reason for extraction of permanent teeth, its correlations with age, gender and education level, as well as identify the important predictors for dental caries in general dental centers in Tehran, Iran.

SUBJECTS AND METHODS

The study was conducted over a period of 6 months; its population consisted of 1,382 patients, aged 9-95 years, who underwent tooth extraction. There were 673 (47.8%) male and 709 (51.3%) female patients. The frequency distribution was calculated using the χ(2) test, ANOVA and t test for differences in mean number of extracted teeth and the logistic regression model to evaluate the variables associated with reasons for tooth extraction.

RESULTS

A total of 2,620 teeth were extracted from the 1,382 patients. The highest rate (36.9%) of extraction occurred for those 41-60 years old. Males comprised 48.7% of patients but had more teeth (1,470, 55.3%) extracted than females (1,150, 43.9%). Nine hundred and thirty-six (67.7%) patients had incomplete secondary education or less. Tooth loss due to caries was 51%; periodontal disease was 14.4%; supernumerary and tooth impaction 13.9%. There was a significant association between patient characteristics (age, gender and education level) and number of teeth extracted.

CONCLUSION

Dental caries and periodontal disease were the main reasons for tooth extraction in Tehran, Iran.

Pre- and postdoctoral dental education compared to practice patterns in special care dentistry

There has been limited research into the impact of predoctoral experiences and postdoctoral general dentistry residencies on the practice patterns of dentists in the care of patients with special or complex needs. This study was undertaken to determine if educational experiences with special populations had a relationship to practice patterns after graduation or residency. University of the Pacific alumni who graduated between 1997 and 2007 were surveyed regarding their pre- and postdoctoral dental education and their practice patterns for the care of patients categorized as medically compromised, frail elders, and developmentally disabled. Definitions for each patient category were provided. Alumni were asked about their practice setting and postdoctoral education. Thirty-one percent (n=526) of those surveyed responded. Regression analyses showed respondents not in private practice were more likely to have completed a postdoctoral general dentistry program (Advanced Education in General Dentistry or General Practice Residency) after dental school compared to respondents in private practice (p<0.001). Across all age groups, respondents not in private practice treated significantly more patients with developmental disabilities than those in private practice (p<0.001). Respondents not in private practice treated more medically compromised patients younger than age sixty-five compared to respondents in private practice (p<0.01). Interestingly, those in private practice treated significantly more patients over sixty-five who were also classified as medically compromised (p<0.05). Pacific alumni who completed postdoctoral training in general dentistry were found to practice more often in non-private practice settings. Alumni in non-private practice settings reported treating a higher percentage of medically compromised patients below age sixty-five than their counterparts in a typical private practice. The pre- and postdoctoral experiences of treating special needs populations appear to have a relationship to graduates' practice setting and patient population.

Economic impact of dental hygienists on solo dental practices

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.

[Distribution of patients' complaints presented to the law court of the Israel Dental Association according to themes, dental area profession and the results]

The purpose of this study was to review the distribution of patients' complains presented to the law court of the Israel Dental Association in Tel Aviv district, according to their topics, dental areas and results. 260 complaint cases filed between 2000 and July 2008 were reviewed. only 186 cases, to which an arbitration proceeding conducted full appeal only, were taken into account . Dentists, who encountered many complaints, were classified according to their country of graduation, as specialists or general dentists. The complaints were classified according to their specific dental field, year of complaint, to the number of arbitrations each year, to the number of appeals each year, to the entity who submitted the appeal, to the difference between the verdict in the District compared to the national ruling, to the distribution of complaints by gender and to the frequency of complaints by anonymous doctors. The distribution of complaints in accordance with topics was as follows: 30% in oral rehabilitation 13.5% in Dental prosthesis, 12.4% in implants, in endodontics 5.3%, 3.7% in maxillofacial surgery, 3.2% on ethics, 2.7% in orthodontics, 1.1% in periodontology 0.5 % in pedodontics and 28% in combined dental domains. 92.5% of complaints filed against dentists who were not experts. 7.5% of the complaints were filed against s specialists. Specialists in the field of oral rehabilitation encountered the largest number of complaints, i.c. 30%. Approximately 35.2% of complaints filed against dentists who have completed their studies in Eastern European countries and 24.9% against the Israeli graduates. 63% of referrals to the Court from Tel Aviv district for which a full arbitration procedure / appeals were presented by women whereas only 37% were presented by men. An analysis of the findings in the difference between the verdicts in the District compared to the national ruling it showed a tendency to aggravation of punishment. (P = 0.003) The Greatest number of appeals was filed in 2001, mostly by patients. In 2004, the greatest number of appeals were filed mostly by dentists. Most appeals have been filed over the years by patients. Against a small number of doctors several complaints were filed. The majority of complaints that were filed in a specific period against one doctor was 6.

General dental practitioners and hearing impairment

OBJECTIVE

Hearing impairment (HI) remains a problem among dentists Hearing loss at speech frequencies was recently reported among dentists and dental hygienists. This study aimed to investigate prevalence and factors associated with perceived HI among dentists.

METHODS

In 2009-2010, 100 general dental practitioners (GDPs) and 115 general (medical) practitioners (GPs) (mean ages, 43.7 and 44.4 years) from Rome (Italy), who commenced practice ≥ 10 years ago, were interviewed on a series of occupation- and recreation-related HI risk factors and on HI-associated symptoms (tinnitus, sensation of fullness, hypoacusis). Prevalence of presumptive HI (≥ 1 symptom perceived during workdays and weekends) was assessed and factors associated with presumptive HI were investigated.

RESULTS

Prevalence was 30.0% (95% confidence interval, 21.0-39.0%) and 14.8% (95% confidence interval, 8.3-21.3%) among GDPs and GPs, respectively. Occupation (GDP vs. GP), family history of hypoacusis, hypertension, ear diseases and smoking were significantly associated with presumptive HI. Within GDPs alone, significant associations were found for frequent use of ultrasonic scalers, use of dental turbines aged≥1 year and prosthodontics as prevalent specialty.

CONCLUSIONS

GDPs experienced HI risk than GPs. Such a risk was not generalized to all dentists, but was specific for those who frequently used noisy equipment (aged turbines, ultrasonic scalers) during their daily practice.

CLINICAL SIGNIFICANCE

GDPs with 10 or more years of practice who routinely use potentially noisy equipment, could be at risk of HI. In order to prevent such condition, daily maintenance and periodical replacement of dental instruments is recommended.

Access to dental care and the capacity of the California dental care system

The authors estimated the following levels of technical efficiency for three types of dental practices in California where technical efficiency is defined as the maximum output that can be produced from a given set of inputs: generalists (including pediatric dentists), 96.5 percent; specialists, 77.1 percent; community dental clinics, 83.6 percent. Combining this with information on access, it is estimated that the California dental care system in 2009-10 could serve approximately 74 percent of the population.

Quality of orthodontic treatment performed by orthodontists and general dentists

OBJECTIVE

To perform a blind comparative evaluation of the quality of orthodontic treatment provided by orthodontists and general dentists.

MATERIALS AND METHODS

Sixty cases of orthodontic treatment were evaluated-30 treated by specialists in orthodontics and 30 treated by general dentists with no specialization course. Orthodontists were selected randomly by lots, in a population of 1596 professionals, and recordings were performed based on the guideline established by the Objective Grading System proposed by the American Board of Orthodontics. Each participant was asked to present a case considered representative of the best outcome among the cases treated, regardless of the type or initial severity of the malocclusion. Statistical analysis involved the chi-square, Wilcoxon, and Mann-Whitney tests. The level of significance was set at P  =  .05 for the statistical tests.

RESULTS

The results showed that 29 orthodontists (96.7%) presented cases considered satisfactory and would be approved on the qualification exam, whereas only 15 dentists (50%) had cases considered satisfactory. Moreover, treatment time was significantly shorter among the orthodontists (P  =  .022), and the posttreatment comparison revealed that orthodontists achieved better outcomes considering all the variables studied.

CONCLUSIONS

Orthodontists spend less time on treatment and achieve better quality outcomes than cases treated by general dentists who have not undergone a specialization course in orthodontics.

Routines for interocclusal appliance therapy among general dental practitioners in a Swedish county

The aims of this study were to investigate what kind of interocclusal appliances that were chosen among Swedish dentists when treating temporomandibular disorders (TMD), the clinical rationale for the treatment, the diagnoses that warranted the appliance treatment, the use of adjunct TMD treatments and prognostic considerations, and possible differences in these respects between children/adolescents and adults with TMD, and, finally, possible differences between private practitioners and general practitioners in the public dental service. During the 12-months-period April 2009-March 2010 all general dental practitioners in the county of Jönköping, Sweden, were asked to fill in a questionnaire when performing a TMD treatment with an interocclusal appliance. A total of 394 questionnaires were filled in and returned, 216 (55%) from dentists in public dental service and 178 (45%) from private practitioners. It was found that in 40% of the cases, no pre-treatment recording of the functional status in the masticatory system had been made. The commonest reasons for the treatment were bruxism, headache, and replacement of a previous appliance. Less than half of the appliances made were hard acrylic appliances. Some kind of adjunct therapy had been made in 22% of the cases treated in public dental service. The corresponding figure for those treated by private practitioners was 25%. Therapeutic jaw exercises was the commonest adjunct therapy followed by selective occlusal adjustment. In the vast majority of cases, the dentists judged the prognosis of the treatment to be good. It is concluded that a large number of appliances made to treat TMD were soft appliances, especially in public dental service. This reflects a possible overuse of soft appliances at the expense of hard acrylic appliances. Furthermore, in a large number of cases, the treatment was performed without any pre-treatment registrations, and adjunct therapies were rarely used. In all these respects,there is an improvement potential for the treatment of TMD in general dental practice.

The use of sedation in the dental outpatient setting: a web-based survey of dentists

There were 7276 e-mail requests sent to dentists in the United States and Canada requesting participation in a short web-based survey to update earlier information regarding the use of dental outpatient sedation. Participants were questioned regarding their use of dental outpatient sedation, including the frequency of use, type of sedation used, route ofadministration, medications used, physiologic monitoring employed, and availability qfantagonist medications and an automated external defibrillator In comparison to earlier studies, the use of outpatient dental sedation continues to change. The use of enteral sedation may be increasing, but now is differentiated by minimal and moderate sedation with different training requirements. The use of parenteral sedation by practitioners also appears to be increasing.

Oral care for special needs patients: a survey of Nebraska general dentists

PURPOSE

The purpose of this survey was to assess the attitudes, behavior, and demographics of general dentists in Nebraska regarding their providing oral health care to patients with special health care needs (PSHCN).

METHODS

A 14-item questionnaire and accompanying cover letter were sent to 800 licensed general dentists in Nebraska. The survey asked for the dentists' demographic information and questions about their PSCHN. Responses to the questionnaire were tabulated, and percent frequency distributions for responses to each item were computed.

RESULTS

Of the 800 surveys sent, 371 (approximately 46%) were returned. Solo practitioners were more likely to report seeing PSCHN (P<.001). Most respondents see all ages, but approximately 10% see only PSCHN over 18-years-old. The most common reasons given to improve the practitioners' ability to care for PSCHN were improved reimbursement (approximately 35%) and more continuing education (approximately 36%).

CONCLUSIONS

These data indicate that most general dentists surveyed in Nebraska see special needs patients of all ages. The most common reasons for not seeing more special needs patients were the level of the patient's disease, the patient's behavior, and insufficient training/experience.

An investigation into the bitewing radiographic prescribing patterns of West Kent general dental practitioners

AIMS

The primary aims of the study were to investigate the use of bitewing radiography within primary dental care and adherence to guidelines on bitewing radiography by general dental practitioners (GDPs) in the West Kent Primary Care Trust (PCT) area. Within the overall aims, the study had objectives to investigate the use of radiographic guidelines, audit and caries risk assessment, the influence of private and National Health Service (NHS) practice, and the influence of the demographic profile of the GDPs on these variables.

METHODS

Data were gathered via a piloted self-completion questionnaire, circulated to all GDPs listed on the NHS Choices website as practising in the West Kent PCT area. Three mailings and follow-up telephone calls were used. The resulting data were entered into a statistical software database and, where relevant, statistically tested, using the chi-square test.

RESULTS

Of 223 GDPs, 167 responded (75%). GDPs with a high NHS commitment were significantly less likely to follow Faculty of General Dental Practice (UK) guidance on prescribing bitewing radiographs for adults (P<0.01) and children (P<0.05) than were mainly private GDPs. Mainly NHS GDPs were more likely 'always/mostly' to follow National Institute for Health and Clinical Excellence guidance (83 compared to 59) (P<0.05) and also to risk-assess patients (83 compared to 62). Only 115 (71%) had carried out a radio graphic audit or peer review in the preceding three years. Those with postgraduate qualifications were more likely (P<0.05) to carry out radiographic audit.

CONCLUSIONS

The study confirmed previous research reporting the under-use of radiography for caries detection and also the failure of some GDPs to comply with ionising radiation regulations. West Kent GDPs with a high NHS commitment were less likely to follow radiographic guidance than their private counterparts. This suggests that further efforts to disseminate information on radiographic guidelines and to educate GDPs are necessary to improve adherence with all aspects of radiography within general dental practice. Research into factors that influence GDPs' decision-making with regards to radiographic prescription may further inform the profession as to the best methods to lead to behavioural change. The dental profession and its regulators need to make a concerted effort to educate and inform GDPs so that this behaviour is modified.

A survey to assess the provision of conscious sedation by general dental practitioners in the Republic of Ireland

AIM

To quantify and qualify how conscious sedation was used in general dental practice before the introduction of formal sedation teaching in the Republic of Ireland.

OBJECTIVES

1. To determine the extent of use of oral, inhalational and intravenous sedation; 2. to determine the training and experience of general dental practitioners providing conscious sedation; 3. to determine the perceived barriers to the practice of conscious sedation; and, 4. to gauge the level of interest in a postgraduate course in conscious sedation.

METHOD

Postal questionnaire sent to one general practitioner in seven, selected randomly from the General Dental Council register, in 2007.

RESULTS

Seventy six percent of respondents agreed that the provision of conscious sedation in general dental practice is important. However, the current provision of inhalation and intravenous sedation by respondents is low in comparison to provision in the UK. The main barrier to the use of conscious sedation in general dental practice appears to be lack of availability of training.

CONCLUSIONS

The data from this study indicated the need for postgraduate training in conscious sedation in Ireland and a need for increased awareness of the Dental Council Code of Practice on sedation.

Informational resources utilized in clinical decision making: common practices in dentistry

This study investigated current trends of Iowa dental practitioners with regard to acquisition and utilization of scientific information resources to support decision making in the clinical practice of dentistry. A survey questionnaire regarding the utilization of various sources of information to support clinical decisions was mailed in September 2009 to all dentists licensed and practicing in the state of Iowa. Dentists appointed full-time within the University of Iowa College of Dentistry were excluded from this study. Continuing education courses were the most frequently utilized and preferred information source by respondents, followed by print journals and consultation with other health care professionals. Practice patterns according to decade of dental school graduation as well as scope of practice were noted. The results of this study demonstrate that dental practitioners utilize a variety of evidence-based and non-evidence-based information resources to support decisions in clinical practice. The habits of newer graduates vary somewhat from those of earlier graduates; the habits of specialists vary from those of general practitioners.

A preliminary analysis of the US dental health care system's capacity to treat children with special health care needs

PURPOSE

The purpose of this study was to use existing data to determine capacity of the US dental care system to treat children with special health care needs (CSHCN).

METHODS

A deductive analysis using recent existing data was used to determine the: possible available appointments for CSHCN in hospitals and educational programs/institutions; and the ratio of CSHCN to potential available and able providers in the United States sorted by 6 American Academy of Pediatric Dentistry (AAPD) districts.

RESULTS

Using existing data sets, this analysis found 57 dental schools, 61 advanced education in general dentistry programs, 174 general practice residencies, and 87 children's hospital dental clinics in the United States. Nationally, the number of CSHCN was determined to be 10,221,436. The distribution, on average, of CSHCN per care source/provider ranged from 1,327 to 2,357 in the 6 AAPD districts. Children's hospital dental clinics had fewer than 1 clinic appointment or 1 operating room appointment available per CSHCN. The mean number of CSHCN patients per provider, if distributed equally, was 1,792.

CONCLUSIONS

The current US dental care system has extremely limited capacity to care for children with special health care needs.

Clinical decision on pit and fissure sealing according to the occlusal morphology. A descriptive study

BACKGROUND

The objective of this descriptive study was to evaluate the clinical decision on sealing pits and fissures according to the occlusal morphology in patients with low individual caries risk (ICR).

MATERIALS AND METHODS

A total of 222 dentists, 86 affiliated to the French Society of Paediatric Odontology (SFOP) and 136 general practice dentists (GPs), answered the same questionnaire with illustrations of 4 occlusal surfaces of permanent molars: they indicated firstly if these were at risk and secondly the corresponding decision regarding sealing. This questionnaire assessed the decision on widening pits and fissures before sealing and the type of sealant material used. Multivariate logistic regression analyses were performed to identify the factors associated with the clinical decision to widen pits and fissures.

RESULTS

Sealing of at-risk teeth was indicated by 89% of dentists, whereas sealing of not at-risk occlusal surfaces was recommended by 46%. SFOP dentists were more prone to recommend pit and fissures sealants. The multivariate analyses demonstrated that only the type of material was associated with the clinical decision to widen pits and fissures. Forty eight percent of dentists choose the same material in all clinical situations.

CONCLUSION

The wide variations in sealant use and placement technique implies there is no apparent consensus among GP and SFOP dentists. Although the criteria are similar in numerous scientific societies, not all dentists are acting upon these recommendations.

Retrospective evaluation of the referral pattern to an oral medicine unit in Ireland

OBJECTIVES

The aims of this study were firstly to examine patient demographics, lesion types and referral sources to Cork University Dental School and Hospital (CUDSH) for oral medicine services and secondly, to indicate factors that could improve the efficiency of the service provided.

METHODS

A retrospective analysis of the clinical records for all new patients, both public and private, seen in the CUDSH oral medicine unit (n = 412) in the calendar year 2007 was undertaken. For each patient the following parameters were recorded: age, gender, residence, referral source and the reason for referral including site of lesion.

RESULTS

The majority of patients were females and the majority of referrals came from general dental practitioners. The most common reason for referral was due to concern about white lesions. Raised soft tissue lesions including epuli and mucocoeles were second and ulceration, including recurrent aphthous and traumatic ulceration, was the third most common reason for referral.

CONCLUSIONS

To our knowledge this is the first study to investigate factors influencing referrals to oral medicine clinics in Ireland. Based on the results presented there appears to be a considerable demand for an oral medicine service dealing with oral lesions and conditions which other practitioners consider to be outside the scope of their practice. Studies of this nature should prove to be valuable in maximising hospital resources at a time when economic factors are leading to increased financial pressure in health care funding.

A cross-sectional survey investigating the care of the primary dentition by general dental practitioners working in Japan and England

OBJECTIVE

To compare treatment decisions about primary dentistry made by Japanese and English general dental practitioners (GDPs).

METHOD

Four clinical scenarios were used to ascertain the clinical opinions of GDPs about what treatment to offer a 6-year-old boy with a carious molar. The first and second scenarios were a single distal and a distalocclusal cavity in a vital tooth without pain. The third was a large distal-occlusal cavity in a non-vital tooth without pain. The fourth was large distal-occlusal cavity in a non-vital tooth with pain. The participants were 234 GDPs in Japan and 322 GDPs in England.

RESULTS

In the first scenario, 62.2% of Japanese GDPs preferred traditional restorative care compared with 34.7% of English GDPs. In the second scenario, Japanese participants were less likely to offer atraumatic treatment (16.5% vs. 34.9%). In the third scenario, Japanese dentists displayed a greater tendency to open the pulp chamber (55.2% vs. 7.6%). In the final scenario, 71% of Japanese GDPs would open the pulp chamber, whereas 50.3% of English GDPs favoured extraction.

CONCLUSION

Japanese and English GDPs differed substantially in their views about the best treatment for a young child with a carious molar.
