Procedures provided to Medicaid recipients by pediatric, general and public health dentists in the commonwealth of Virginia: fiscal years 1994 and 1995.

PURPOSE: The purpose of this study was to report any differences found among the mean percentages of procedures performed by three types of dental providers for each type of service performed. The study focused on the types of services provided by dentists to Medicaid children in Virginia. METHODS: Medicaid claims field for dental patients younger than age 21 were obtained and analyzed for fiscal years 1994 and 1995. Dental providers were categorized according to their practice: general practice (GP), pediatric dentist (PD) and public health dentist (PH). Each type of practitioner (GP, PD, and PH) was evaluated for percentages of diagnostic, preventive, and corrective services provided to their Medicaid patients. The preventive category was subdivided into preventive services (scaling, prophy, fluoride and oral hygiene instruction) and sealant services. RESULTS: For each type of service, the mean percentages of procedures performed were compared among the three types of dental providers. The evaluation of the diagnostic procedure variable resulted in the finding that GP practitioners performed a significantly greater percentage of diagnostic procedures to their Medicaid patients than do PD and PH dentists (p < 0.0001). The percentage of preventive procedures performed by PD and GP dentists was not significantly different but was significantly lower than those performed by PH dentists (p < 0.0001). Finally, PD dentists performed a significantly greater percentage of corrective procedures than both GP and PH dentists (p > 0.0037). CONCLUSION: Differences were found among the mean percentages of procedures performed by the three types of dental providers for each type of service performed.     

Rural versus urban analysis of dental procedures provided to Virginia Medicaid recipients

PURPOSE: The purpose of this study was to report the distribution of procedures provided to Virginia Medicaid children by 3 types of dental providers in rural and urban areas. METHODS: Medicaid claims filed for dental patients less than 21 years old were obtained and analyzed for fiscal years 1994-1995. Dental providers were categorized according to their practice type: (1) general practice (GP); (2) pediatric (PD); and (3) public health (PH) dentists. Each type of practice was categorized as practicing in a metropolitan, urban, rural, or completely rural location and evaluated for percentages of preventive, diagnostic, and corrective services provided. RESULTS: Rural areas had a higher percentage of significant providers than did metropolitan or urban areas. General dentists performed more diagnostic and preventive but fewer corrective procedures than pediatric dentists. Pediatric dentists and general dentists in completely rural areas performed more corrective procedures than their counterparts in metropolitan or urban areas. CONCLUSIONS: General, pediatric, and public health dentists in metropolitan and urban areas perform slightly more diagnostic services and fewer corrective services than practitioners in more rural areas.     

The provision of orthodontic services by general dental practitioners. 1. Methods and descriptive results

Information regarding orthodontic service provision by general dental practitioners in Australia is limited. The aim of this survey was to determine the amount and variety of orthodontic services provided by general dental practitioners in the Melbourne Statistical Division, Victoria, Australia. A random sample of 307 dentists drawn from the Victorian Dentists Register was surveyed by mailed questionnaire: 218 (71%) replied. Data were collected using a fortnight log. During this time 59 per cent of the dentists saw at least one orthodontic patient; one dentist saw 66 orthodontic patients. Removable orthodontic appliances were used by 35 per cent of the dentists and fixed orthodontic appliances by 18 per cent. Twenty-six per cent provided comprehensive orthodontic treatment, 22 per cent aligned incisors, and 21 per cent corrected anterior cross-bites. The general dental practitioners surveyed provided a wide range of preventive and interceptive orthodontic services to generally a small percentage of their patients.     

Variations in self-reported provision of services by general dentists in private practice

BackgroundVariations in dentists&;apos; provision of services have been documented, but information about contributing factors is limited.MethodsThe authors used responses to a 2003 survey of general dentists in private practice in California (46 percent response rate; 3,098 dentists included in the final sample) to assess variations in service provision and its correlates. They used logistic regressions to assess the correlation of various characteristics with the self-reported percentage of time spent providing services.ResultsThe results show variations in services provided by general dentists in private practice. Multiple factors, including the dentist&;apos;s sex, region of practice, employment of hygienists, patients&;apos; race and population income in the area of practice were significantly and independently associated with provision of services.ConclusionsThe survey results reflect practice variations that existed before the latest economic downturn, which resulted in a loss of jobs and medical and dental insurance. The data serve as the baseline for future studies of changes in dental practice and for assessing the impact of the 2010 health care reform legislation on dental practice.Practice ImplicationsImprovements in oral health care, the recent economic decline and health care reform may lead to changes in dental practice and in the dental workforce.     

Dentists' Attitudes and Practices Toward Provision of Orthodontic Treatment for Children with Visual and Hearing Impairments

The objective of this study was to determine differences in behavior and attitudes of dentists in Riyadh, Saudi Arabia, in providing orthodontic care for children who are sensory impaired. A self‐administered questionnaire was sent to all dentists working in Riyadh to assess the following domains: personal characteristics of the dentists and their practices, provision of dental care for children who are visually‐impaired (VI) and/or hearing‐impaired (HI), and their attitude toward providing orthodontic care for these children. Attitudes were measured on two scales and the overall score of these two scales represented each respondent's attitude. Thirty percent of the dentists provided dental care for children with VI and 45.3 percent did for children with HI. The provision of orthodontic care was significantly affected by the country in which the dentists had received their dental training, both for children with VI and HI (p<0.01), and by number of years they had been in practice for children with VI (p<0.05). Regression analysis showed that only the country of dental training significantly affected the dentist's attitude score. There were also significant variations in attitudes toward the provision of orthodontic treatment for children with sensory impairment (SI), influenced by dental training and experience. In practical terms, this means that improvement in attitudes needs to be initiated at the dental undergraduate level. Establishing global guidelines for the provision of orthodontic treatment for patients with sensory impairment is likely to assist both professionals and patients.     

Caries management decision: Influence of dentist and patient factors in the provision of dental services

Objectives

Little is known about how dentists implement caries management and provide restorative dental services in everyday practice. This study explored whether or not recent concepts in caries management were implemented in practice by private practitioners. The influence of patient and practitioner characteristics on the provision of restorative dental services was also investigated through multidimensional analyses.

Methods

A sample of French general private dental practitioners was asked to record the characteristics of 35 preventive or restorative treatments made on vital permanent teeth. The data collection form was designed to explore dentists’ attitudes towards caries management and their use of minimally invasive therapies.

Results

Twenty-six practitioners recorded the characteristics of 921 treatments performed on 457 patients. Results indicate that participants rarely performed non-invasive treatments. They used an inappropriate detection tool, as most of decisions to treat were based on visual inspection frequently associated with probing. Multidimensional analysis showed that dentists provided different restorative treatments depending on patient characteristics, with minimally invasive, esthetic restorations preferentially performed for healthy, young and well-insured patients. Restorative treatments and detection tools also varied markedly among practitioners. These variations in service patterns were not related to a specific patient profile in each dental practice.

Conclusions

Results indicate that recent concepts in caries management have not yet been adopted in everyday practice. Patient and dentist characteristics influence the provision of restorative dental services. Decision-making in caries management not only depends on pathophysiology but also seems to be influenced by many other factors.     

Cost and productivity analysis of orthodontic care in Finland

Abstract– The aim of the study was to investigate the costs of orthodontic care provided for children and adolescents up to the age of 18 by municipal health centers in Finland, and to study the productivity of these services. The data were gathered by a questionnaire sent to all health centers; 96% responded. The majority of respondents estimated the share of orthodontic care as 10% of the total gross costs of dental care, given that 14% of all dental visits were for orthodontic reasons. To study the productivity in individual health centers, the output was measured by the estimated number of completely treated patients. The cost of orthodontic treatment per completely treated patient was, on average, FIM 7358, ranging from FIM 1299 to FIM 24 751. The strongest explanatory factor for the average total costs of orthodontic clinics was the number of general dentists with little experience in providing orthodontic treatment. Other explanatory factors were the number of orthodontists or experienced dentists, the percentage of orthodontic tasks performed by auxiliary personnel, and the timing of treatment. Savings might be obtained by devolving treatment to orthodontists or experienced dentists in-stead of to dentists with little orthodontic experience, and by starting treatment early. The estimated optimal size for an orthodontic clinic was found to be a unit with 830 completely treated patients per year, but most of the orthodontic clinics were in fact much smaller with, on average, 133 completely treated patients per year.     

The delivery of orthodontic care in New Zealand. Part II: Analysis of a census of dentists

Part I of this study reported the level and distribution of the supply of specialist orthodontic services in New Zealand. This paper focuses on the amount and variety of orthodontic services supplied by dentists. A questionnaire sent to all dentists in New Zealand sought information on the amount and type of orthodontic treatment carried out between 1 July 1998 and 30 June 1999. The reply rate was 80.9 percent. The majority of dentists carried out some form of orthodontic treatment, predominantly of a minor nature. A small number provided significant amounts of treatment, both simple and complex. The majority of orthodontic treatment and the majority of comprehensive fixed-appliance treatment were undertaken by orthodontists. One-quarter of all orthodontic patients in New Zealand were treated by dentists, irrespective of the complexity of treatment. Nearly a fifth of all full fixed upper and lower appliances, and nearly a third of all single-arch fixed appliances were placed by dentists during the study period. In general, male dentists, dentists over the age of 40, those who had attended an orthodontic continuing education course in the previous 5 years, and those who referred fewer patients to an orthodontist carried out more procedures, including those of a complex nature; they also had a higher average active orthodontic patient load. Wanting to be more or less busy had little influence on the amount or complexity of treatment performed. Dentists in regions with a low supply of specialist orthodontic services provided more comprehensive fixed appliance treatment and had a higher orthodontic patient load. However, the presence or absence of an orthodontist in an urban area seemed to have little impact on the complexity of treatment or the orthodontic patient load of dentists. Despite fewer orthodontists in secondary and minor urban areas, dentists in these areas did not have a higher orthodontic patient load, but carried out a wider range of procedures and more complex procedures than those in main urban areas.     

Distribution of orthodontic services and fees in an insured population in Washington.

Previous attempts to quantify the amount and type of orthodontic therapy provided by nonorthodontists in the United States have relied on survey data. Although there are advantages to surveys, such as control over survey recipients and inclusion of specific questions, they also have limitations, such as low response rates, response bias, and recall bias. This study used insurance claims data from a large dental benefits provider in Washington to assess the distribution of orthodontic services and fees among various dental providers. All orthodontic claims allowed by Washington Dental Service in 2001 were retrieved, along with treatment codes, fees, and demographic information for both patients and providers. A total of 102,984 orthodontic claims were included in the study. General dentists submitted 7.0% of these claims, orthodontists submitted 90.9%, and pedodontists submitted 1.9%. Orthodontists submitted higher average fees for space maintainers, first payments, and records. The percentage of orthodontic treatment preformed by general dentists and pedodontists in this claims-based study was substantially less than what has been previously reported in survey-based studies. Additionally, a smaller percentage of general dentists and pedodontists in this study performed comprehensive treatment, compared with previous studies. This study illustrates the value of insurance claims data to assess the provision of orthodontic care.     

The provision of periodontal services in general dental practice in Australia

Recent studies have documented the low percentage of professional services which are associated with periodontal care. The aims of the present study were to describe the provision of periodontal services by private general practice dentists in Australia and to investigate the variation of provision of periodontal services. Using a day log approach via a mailed questionnaire one in eight services provided were found to be related to periodontal care. Most were of a preventive nature. There was great variation between dentists in the number of services provided indicating the possibility of both under and overservicing. The findings are discussed with regard to the changing philosophies of provision of periodontal services and known methods of eliciting change among providers.     

General dentists and pediatric dental patients: the role of dental education

The objective of this study was to investigate whether undergraduate dental education affects general dentists' practice characteristics, attitudes, and professional behavior concerning the treatment of pediatric patients. Data were collected with a self-administered mailed survey from 241 general dentists who were members of the Michigan Dental Association (response rate=48.2 percent). While 40.4 percent of the respondents reported that their dental education had prepared them well to treat child patients, only 33.4 percent indicated that their clinical education had prepared them well. The level of educational preparedness was significantly correlated with a) practice characteristics such as how well the practice was set up to treat children and how knowledgeable and comfortable the staff was concerning providing care for children, b) attitudes concerning the treatment of child patients, and c) professional behavior such as the types of services provided for child patients versus the number of referrals made. The findings strongly suggest that educational experiences concerning the treatment of pediatric dental patients will shape future dental care providers' attitudes and professional behavior. Given the lack of access to dental care for children, it seems crucial to carefully evaluate undergraduate dental curricula to ensure that future dental care providers receive sufficient educational and especially clinical experiences concerning the treatment of child patients.     

Orthodontic treatment provided by pediatric dentists.

The purposes of this study were to document orthodontic treatment currently provided by pediatric dentists for comparison with past and future studies and to ascertain variables that influence practitioners' orthodontic treatment patterns. A 25-item survey was mailed to 492 diplomates of the American Board of Pediatric Dentistry. Surveys returned within 16 weeks were included for statistical analysis. The response rate was 73%. Most practitioners spent less than 10% of their practice time providing orthodontic treatment and reported that this would not change in the future. Practitioners who were dual trained in pediatric dentistry and orthodontics spent more time providing orthodontic treatment, although nearly half spent at least 50% of their time providing traditional pediatric dental treatment. Most pediatric dentists provided orthodontic treatment in the primary or early mixed dentition stages. The most common conditions treated were anterior crossbite, ectopic eruption, habits, posterior crossbite, and space maintenance. The most common orthodontic appliances used were fixed rapid palatal expanders and removable Hawley appliances with finger springs. Orthodontic treatment provided by pediatric dentists has decreased since it was last surveyed in 1983 and is not expected to change in the next 5 years.     

Geographic distribution of specialist orthodontists and orthodontic providers in Japan

ObjectiveThis study aimed to clarify the geographic distribution of specialist orthodontists and dentists who provide orthodontic services in Japan.MethodsWe obtained data on the populations of 1750 municipalities in Japan in 2010 by referring to the census. We obtained data on the number of dentists who mainly provide orthodontic services (specialist orthodontists) and the number of dentists, including general dentists, who provide orthodontic services (orthodontic providers), by referring to the Survey of Physicians, Dentists, and Pharmacists. Furthermore, we referred to the directory on the website of the Japanese Orthodontic Society (JOS) to obtain data on JOS-qualified orthodontists. To assess the distribution of specialist orthodontists and orthodontic providers, we used Lorenz curves and Gini coefficients.ResultsThe median value for the number of specialist orthodontists and number of JOS-certified orthodontists per 100,000 persons aged between 5 and 40 years old was 0, while that of orthodontic providers was 27.5. Gini coefficients for specialist orthodontists and JOS-certified orthodontists were 0.523 and 0.615, respectively. On the other hand, the Gini coefficient for orthodontic providers was 0.258.ConclusionsRegional inequalities in the availability of specialist orthodontists are high, and medical access to specialist orthodontic services may be limited in areas other than urban districts. In municipalities with a population of fewer than 50,000 inhabitants, the number of specialist orthodontists was very low, but orthodontic providers were relatively evenly distributed. Our research results suggested that studying the distribution of specialist orthodontists and orthodontic providers can provide valuable information for developing dental care policies.     

The use of dental anxiety questionnaires: a survey of a group of UK dental practitioners

AIM: To determine the frequency of use of dental anxiety assessment questionnaires and factors associated with their use in a group of UK dental practitioners. METHOD: A postal questionnaire to all 328 dentists whose names appear in the British Society for Behavioural Sciences in Dentistry Directory. Information collected for each practitioner included gender, year of qualification, type of practice in which anxious dental patients were treated, treatment used to manage anxious dental patients, type and frequency of use of dental anxiety assessment indices. RESULTS: Questionnaires were returned from 275 (84%) practitioners. 269 were analyzed. Only 54 practitioners (20%) used adult dental anxiety assessment questionnaires and only 46 (17%) used child dental anxiety assessment questionnaires. Male practitioners were more likely to report questionnaire use in comparison with females (P< 0.05), when treating dentally anxious adults (26% v 14%). In addition, practitioners providing intravenous sedation were more likely to use an adult dental anxiety questionnaire (P < 0.04) than those who did not use intravenous sedation (29% v 15%). The type of treatment provided had a significant association with the use of child dental anxiety. Those providing general anaesthesia (P = 0.03) and hypnosis (P = 0.01) for dentally anxious children were more inclined to use a questionnaire. CONCLUSION: The use of pre-treatment dental anxiety assessment questionnaires was low in this group of dentists. Male practitioners and those providing intravenous sedation, general anaesthesia or hypnosis seem more likely to use dental anxiety assessment questionnaires.     

Infant oral health care: a survey of general dentists, pediatric dentists, and pediatricians in Virginia

PURPOSE: This study's purpose was to examine the current knowledge, attitudes, and experiences related to infant oral health for dental and medical providers in Virginia. METHODS: A survey of infant oral health care was sent to: (a) 300 randomly selected general dentists; (b) 300 randomly selected pediatricians; and (c) all pediatric dentists in Virginia. Survey respondents were tabulated, and percent frequency distributions for responses to each item were computed. RESULTS: The surveys return rate was 48%. A total of 100% of pediatric dentists treated infants and were more likely to recommend that children be seen by age 1 (P < .001). All pediatricians treated infants as well, while only 5% referred for the first dental visit by 1 year of age. Forty-five percent of general dentists surveyed treated infants, and only 12% referred for the first dental visit by 1 year of age. The logistic regression results indicated that there were differences between practitioner type regarding the recommended age of the first dental visit and years in practice. CONCLUSIONS: The majority of pediatricians and general dentists are not advising patients to see the dentist by 1 year of age. There is a need for increased infant oral health care education in the medical and dental communities.     

Service provision trends among Australian private general dental practitioners: 1983/84 to 1998/99

AIM: To investigate time trends in service provision. DESIGN: Four cross-sectional surveys across a 15-year period. SETTING: Australian private general practice. PARTICIPANTS: A random sample of dentists. METHODS: Dentists were surveyed by mailed questionnaire in 1983, 1988, 1993 and 1998 (response rates 71%-75%). Data were weighted to provide representative estimates for the age by sex distribution of private general practitioners in 1983, 1988, 1993 and 1998. MAIN OUTCOME MEASURES: Services per visit, annual services per dentist, annual services per patient. RESULTS: Total services per visit increased over the study period from 1.78 to 2.14 (Poisson regression; p < 0.05). However the annual number of services provided per dentist did not vary significantly, reflecting a trend among dentists to supply fewer patient visits per year. The annual number of services provided per patient increased over the period from 3.47 to 5.22 (OLS regression; p < 0.05), reflecting both the increased service rate per visit and increased numbers of visits by patients. Dentists provided less restorative, prosthodontic and extraction services per year, but more endodontic and crown and bridge services. The pattern of annual care received per patient also included more endodontic and crown and bridge services but differed from the dentist pattern through increased service rates over the study period in areas such as restorative, diagnostic and preventive. CONCLUSIONS: While dentists are providing a similar number of services annually, the content of their workload has changed to include less emphasis on removal and replacement of teeth and more effort on maintenance and retention of natural dentitions.     

The delivery of orthodontic care in New Zealand. Part I: Analysis of a census of orthodontists.

A two-part study was undertaken to determine the supply of orthodontic services in New Zealand. Part I focuses on services supplied by specialist orthodontists. A companion paper will describe the amount and characteristics of orthodontic services supplied by dentists. All orthodontists in New Zealand in 1999 were surveyed to provide information on practice location and days practiced in 1996 (the year of the last population Census), and the amount and type of orthodontic treatment carried out in the year 1 July 1998 to 30 June 1999. The response rate was 78.9 percent. Data from 1996 were used to establish and quantify the location and distribution of orthodontists in New Zealand, and their spatial relationship to 12-year-olds and 10- to 14-year-olds using Geographic Information Systems. The information from 1998-1999 was used to determine the amount and variety of services provided by orthodontists and the makeup of their patient base. Nearly two-thirds of orthodontists had a branch practice. Over 50 percent of the 10- to 14-year-old population resided within 5 km of an orthodontist, and nearly three-quarters within 10 km. Disparities between regions existed in the supply of specialist orthodontic services. The catchment areas of main urban areas had more than three times the supply of orthodontists to 12-year-olds than did the secondary and minor urban areas combined. The mean average active patient load was 371, and the mean number of full upper and lower fixed appliances placed was 130.3 during the year of the study. Nearly half of all patients had been referred from dentists, approximately one-quarter were self-referred, and a quarter had been referred by dental therapists. Adults comprised 12.1 percent of the patient load of orthodontists; 60 percent were female.     

Teledentistry in rural California: a USC initiative

Dentistry, in a synergistic combination with telecommunications technology and the Internet, has yielded a relatively new and exciting field that has endless potential. "Teledentistry" emerges from the fusion of dental practice and technology and can take on two forms--real-time consultation and "store and forward." The first entity to put teledentistry into practice was the Army, which, in 1994, successfully undertook consultations between dentists and service personnel located more than 100 miles apart. Since then, various institutions and organizations in the United States and farther afield have practiced teledentistry, with varying degrees of success. The Children's Hospital Los Angeles Teledentistry Project, being run in association with the University of Southern California's Mobile Dental Clinic, seeks to increase and enhance the quality of oral health care that is provided to children living in remote rural areas of California, areas often severely underserved by dental health providers. The project has three phases: Phase I involves the establishment and organization of the teledentistry network; Phase II will introduce technologies to provide orthodontic consultation and treatment; and Phase III will expand the network and provide increased specialty care into further areas of California and beyond, providing services to more children in desperate need of dental health care.     

Gender differences in career and practice patterns of PGD-trained dentists

This study compares differences by gender in the practice patterns and professional activities of general dentists, specialists, and dentists with Advanced Education in General Dentistry (AEGD) or General Practice Residency (GPR) training. The UCLA School of Dentistry surveyed a random sample of 6,725 dentists graduating from dental school in 1989, 1993, and 1997 as part of an evaluation of the impact of federal funding on postgraduate general dentist (PGD) programs. The survey asked about current practice, services referred and provided, and professional activities. Of the 2,029 dentists (30 percent) who responded, 49 percent were general dentists with no specialty training; 7 percent had AEGD training; 20 percent had GPR training; and 24 percent had specialty training. General dentists were more likely to be in private practice (p < 0.05). AEGDs, specialists, and females were more likely to report faculty positions as a secondary occupation. General dentists were more likely to be practice owners than AEGD- or GPR-trained dentists. The mean number of patients seen was highest for specialists. Females reported fewer patients than males, and this difference was significant for GPR-trained dentists. With respect to services, GPR-trained dentists reported significantly more biopsy procedures, conscious sedation, periodontal surgery, and implants than general dentists. AEGD-trained dentists reported more conscious sedation than general dentists. GPR dentists were more likely to volunteer time than general dentists without specialty training. PGD training appears to result in different types of employment and specific practice patterns that strengthen primary care dentistry. We further conclude that there are gender differences in the types of practice, patients seen, and services provided. These findings occur in addition to training differences.
