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.     

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.     

National Survey of Korean Dentists' Knowledge and Opinions: Dental Caries Etiology and Prevention

Objectives : Dentists have the potential to influence what their patients know and do regarding dental caries prevention. The practices of dentists and what they tell their patients are influenced, in part, by their own knowledge and opinions. The purposes of this study were to determine the level of knowledge and opinions about caries etiology and prevention among Korean dentists and to describe related factors. Methods : A pretested, 27-item questionnaire was mailed to 2,047 dentists, selected by a stratified random sampling allocated proportionately. A postcard reminder was sent to all dentists after one week. Nonrespondents were sent additional complete mailings after three, seven, and nine weeks. The response rate was 83 percent (n=1,700 dentists). Results : Analysis of six factors thought to be related to knowledge about caries etiology and prevention showed that recent graduates and dentists who worked in public health centers were likely to be more knowledgeable about caries etiology and prevention than their counterparts (P<.05). In regression analysis of perceived effectiveness of caries-preventive procedures for children, recent graduates, males, and dentists who worked in public health centers tended to rate caries-preventive procedures more effective than other dentists (P<.05). Dentists who had experience with school-based preventive programs and dentists in rural areas were likely to rate caries-preventive procedures for adults more effective than other dentists (P<.05). Conclusion : Overall, results of this study suggest that the majority of dentists do not know current information concerning etiology and prevention of dental caries, mechanisms of action of fluoride, and effectiveness of preventive procedures for children and adults. Efforts to enhance the level of knowledge and practices of Korean dentists about caries prevention should focus on strategies to educate older graduates and female dentists, especially those in private practice.     

General dentists' perceptions of educational and treatment issues affecting access to care for children with special health care needs

This study analyzed a data subset of a national survey of general dentists conducted in 2001 to determine their overall care of children with special health care needs (CSHCN). In the survey, dentists were asked to respond to questions in the following areas: did they provide care for CSHCN (children with cerebral palsy, mental retardation, and those who are medically compromised); what were their perceptions of the training they received in dental school related to CSHCN; what was their interest in additional training for CSHCN; and what factors influenced their willingness to provide care for CSHCN? Only about 10 percent see CSHCN often or very often, and only one in four respondents had hands-on experience with these patients in dental school. Postgraduate education in general practice or advanced general dentistry residency had no effect on willingness to care for CSHCN. Older dentists, those accepting Medicaid for all children, and those practicing in small communities were more likely to see CSHCN. Dentists willing to see CSHCN also were more likely to perform procedures associated with special needs and underserved child populations including pharmacologic management and stainless steel crowns. Dentists with hands-on educational experiences in dental schools with CSHCN were less likely to consider such factors as level of disability and patient behavior as obstacles to care and were more likely to desire additional education in care of CSHCN.     

Use of dental services: an analysis of visits, procedures and providers, 1996

BACKGROUND: While many studies have provided data on Americans' access to dental care, few have provided a detailed understanding of what specific treatments patients receive. This article provides detailed information about the types of dental services that Americans receive and the types of providers who render them. METHODS: The authors provide national estimates for the U.S. civilian noninstitutionalized population in several socioeconomic and demographic categories regarding dental visits, procedures performed and the types of providers who performed them, using household data from the 1996 Medical Expenditure Panel Survey, or MEPS. RESULTS: Data show that while the combination of diagnostic and preventive services adds up to 65 percent of all dental procedures, the combination of periodontal and endodontic procedures represents only 3 percent. Additionally, while 81 percent of all dental visits were reported as visits to general dentists, approximately 7 percent and 5 percent of respondents who had had a dental visit reported having visited orthodontists or oral surgeons, respectively. CONCLUSION: MEPS data show the magnitude and nature of dental visits in aggregate and for each of several demographic and socioeconomic categories. This information establishes a nationally representative baseline for the U.S. population in terms of rates of utilization, number and types of procedures and variations in types of providers performing the procedures. These nationally representative estimates include data elements that describe specific dental visits, dental procedures and type of provider, and they offer details that are useful, important and not found elsewhere. PRACTICE IMPLICATIONS: By understanding these analyses, U.S. dentists will be better positioned to provide care and better meet the dental care needs of all Americans.     

Dentist use patterns for pit and fissure sealants and topical fluorides

A survey of 2,800 general dentists from six licensing regions was conducted to determine the current rate of pit and fissure sealants and topical fluoride use. The response rate was 56 percent. Seventy percent of general dentists used sealants on newly erupted secondary teeth and 20 percent of general dentists had never used sealants. Sixty-five percent of general dentists used topical fluorides on pedodontic patients at six-months intervals and 25 percent used them at one-year intervals. Dentists with more frequent use of sealants tended to be recent graduates who used new procedures, spent more practice time in pedodontics, came from the central region, had a hygienist in their practice, and belonged to the Academy of General Dentistry. Dentists with more frequent use of topical fluorides tended to perform frequent recall examinations. Those who performed frequent recall examinations were more likely to come from Florida and the Southeast, to believe caries spread rapidly, to be recent graduates, and to have a greater percentage of patients with insurance.     

Training for dentists in smoking cessation intervention

BACKGROUND: Although dentists are ideally placed to deliver smoking cessation advice and assistance to their patients, smoking cessation interventions are not often incorporated as a routine part of dental care. Research is needed to identify factors that facilitate and inhibit dentists' capacities to deliver smoking cessation advice. METHODS: An initial focus group discussion was conducted in Melbourne with 10 dentists. Six Victorian country dentists were interviewed in depth by telephone. Following this qualitative data collection, a random sample of 250 dentists (response rate of 57 per cent) was interviewed by telephone. Dentists were asked about their perceived role, current practices, knowledge of resources and services and opinions on training in relation to smoking cessation. RESULTS: Dentists are willing to ask and advise patients about smoking, but are less inclined to assist patients to quit or arrange follow-up. Dentists are more likely to implement one-off, opportunistic interventions rather than take a systematic preventive approach. Dentists are interested in attending further education and say they require training to be relevant to the context of their day-to-day running of the dental practice. CONCLUSIONS: Training should aim to legitimize the dentist's role in smoking cessation and provide strategies and resources so that dentists can practise interventions as part of their day-to-day work.     

Knowledge of oral cancer risk factors and diagnostic concepts among North Carolina dentists. Implications for diagnosis and referral

BACKGROUND: Dentists play a critical role in the early detection of oral and pharyngeal cancer (OPC). The authors administered a survey that assessed the level of knowledge among dentists regarding risk factors and diagnostic concepts. METHODS: In 2002, the authors mailed a 38-item, pretested survey to a random sample of 1,115 licensed dentists practicing in North Carolina. Three-level (low, medium, high) composite index scores for knowledge of risk factors and diagnostic concepts were created using previously developed scales. The authors formulated multivariable models for risk factor and diagnostic knowledge indexes. RESULTS: Of the 584 respondents, only 181 (31 percent) had consistent medium-to-high levels of knowledge on both highly correlated indexes. Dentists who had higher risk factor and diagnostic knowledge scores were significantly (P < .05) more likely to have heard of one or more diagnostic aids (odds ratio [OR], 2.7), to have graduated from dental school within the previous 20 years (OR, 1.8) and to have performed biopsies or referred five or more patients with suspicious lesions per year (OR, 1.7 and 1.5, respectively) than were less-knowledgeable respondents. CONCLUSIONS: More education is needed in dental schools, postgraduate programs and continuing education programs to enhance dental professionals' knowledge of OPC risk factors and diagnostic concepts. Such programs should include information about adjunctive diagnostic aids. PRACTICE IMPLICATIONS: Greater knowledge of risk factors and diagnostic concepts may result in more frequent patient referrals, biopsy procedures or both, thus aiding in the early diagnosis and treatment of patients with OPC.     

The professions of dentistry and dental laboratory technology: improving the interface

BACKGROUND: Dentistry's mission to provide rehabilitation services to patients who experienced dental disease is being jeopardized through the continual reduction of critical to quality skills and knowledge in dental laboratory technology being offered in dental and dental laboratory technician education. These reductions are creating a shortage of knowledgeable dentists and dental laboratory technicians who will be needed to address the projected public demand for laboratory-fabricated tooth replacements and restorations. METHODS: Demographic trend analysis supports a hypothesis that without immediate action by dentistry, substantial patient needs will not be met owing to inadequate levels of dental laboratory support for general dentists. RESULTS: The sophistication of laboratory-based rehabilitative and elective therapies demand closer cooperation between dentists and dental laboratory technologists. CONCLUSIONS: Dentistry must not abdicate its responsibilities in dental technology as it pursues a path away from rehabilitation services toward a projected future of prevention services. With decreasing educational exposure and training in dental laboratory procedures, dentists will have difficulty participating with dental laboratory technologists to fabricate laboratory-based rehabilitative and elective therapies. Without significant guidance from dental professionals in establishing laboratory standards in both education and practice, proprietary interests and commercial biases may set the laboratory and clinical standards of the future. CLINICAL IMPLICATIONS: Dentists will have limited experience or background to evaluate the dental laboratory technology offered in the marketplace and will be subject to the marketing of the industry. A shortage of educationally trained dental laboratory technologists will create a clinical and an economic burden on both dentists and patients.     

AIDS and Dental Practice

Dental health care workers (DHCWs) can provide important diagnostic, treatment, and referral services for patients with AIDS and at risk for AIDS. They also have a responsibility to protect all patients in their practices, and themselves, from infectious disease transmission through the use of infection control. To determine the extent to which DHCWs are prepared to assume these responsibilities, a randomized survey of California DHCWs was conducted. Responses were obtained from 297 dentists, 128 hygienists, and 177 dental assistants. DHCWs who expressed a greater willingness to treat people with AIDS or HIV infection also practiced more thorough infection control. Respondents in all groups who perceived a greater percent of their patients to be at risk for AIDS were more likely to use infection control procedures (P less than .0001). They also were more willing to treat such patients (P less than .004) and were more likely to assess patients for AIDS by taking a thorough medical history (P less than .02) and sexual history (P less than .04). Since attitudes toward AIDS and perception of the percent of patients at risk in one's practice affect patient assessment and infection control procedures used by dental health care workers, educational programs designed to enhance DHCWs' response to the HIV epidemic should alert them to the extent of the problem and help them cope with their concerns.     

Secular trends in dental services provided by dental therapists and dentists in Southwest Alaska

BackgroundThe goal of the study was to identify secular trends in dental service delivery between dental therapists and dentists in the Yukon-Kuskokwim Delta region of Southwest Alaska, the first area of the United States to authorize dental therapy practice.MethodsElectronic health record transactions from the Yukon-Kuskokwim Health Corporation from 2006 through 2015 (n = 27,459) were analyzed. Five types of dental services were identified using Current Dental Terminology procedure codes: diagnostic, preventive, restorative, endodontic, and oral surgery. Main outcomes were percentages of services provided by dental therapists compared with dentists and population-level preventive oral health care.ResultsThe overall number of diagnostic, preventive, and restorative services in the Yukon-Kuskokwim Delta increased. For diagnostic services, there was a 3.5% annual decrease observed for dentists and a 4.1% annual increase for dental therapists (P < .001). Similar trends were observed for restorative services. For preventive services, there was no change for dentists (P = .89) and a 4.8% annual increase for dental therapists (P < .001). Dental therapists were more likely than dentists to provide preventive care at the population level.ConclusionsDental therapists have made substantial contributions to the delivery of dental services in Alaska Native communities, particularly for population-based preventive care.Practical ImplicationsThe study’s findings indicate that there is a role for dental therapy practice in addressing poor access to oral health care in underserved communities.     

Service mix in general dental practices employing and not employing dental hygienists

Abstract Service mix studies conducted in Australia have indicated a low provision of periodontal services. The service mix in Australian general dental practices employing dental hygienists has not been studied. This study compares the service mix between 18 practices employing hygienists and 29 practices not employing hygienists in Adelaide. Practices employing hygienists tended to be larger group practices, with younger dentists seeing a younger set of patients. Practices employing dental hygienists provided a mean of 97.9 services to 57.2 patients over 2 days, significantly higher than the mean of 68.8 procedures to 39.1 patients in practices not employing dental hygienists. Comparing the % of procedures provided in treatment categories as a ratio of total procedures, practices employing dental hygienists provided significantly more periodontal procedures and less oral surgery, prosthetic and restorative procedures. Periodontally-related services accounted for an average of 37.7% of procedures in practices employing dental hygienists compared with 18.9% in practices not employing dental hygienists (p(0.05). Periodontal and preventive treatment of 50.7%) of patients in practices employing hygienists was delegated to a hygienist, and the level of delegation of periodontally-related procedures was 77.2%. Over 90% of procedures performed by hygienists were periodontally-related, with the removal of subgingival calculus accounting for 57.7% of all procedures provided by dental hygienists. In conclusion, practices employing hygienists had a more periodontally-orientated service mix, with hygienists acting to complement the services of dentists in the provision of periodontal services, rather than as a substitute for the dentist.     

Rural dentists: Does growing up in a small community matter?

BackgroundThe aging of the dental work-force has implications for both patients and dentists, especially those in rural and underserved areas. Anecdotal information regarding dental workforce trends indicates that students from rural communities are more likely to practice in rural communities than are students from urban areas. Although the medical literature supports this premise relative to physicians, there are no data to verify this statement relative to dentistry. Therefore, the authors decided to study whether this premise applies to dentistry.MethodsThe authors conducted a retrospective analysis of dental student records from a Midwestern dental school for the years 1980 through 2010 to determine if there was a statistical correlation between the size of a dental student's town of origin and the size of the community where he or she practiced after graduation. They also examined what role, if any, the student's sex played.ResultsDentists from rural areas were approximately six times more likely to practice in a rural area than were dentists from urban areas. Female dentists were only slightly less likely to practice in a rural community than were male dentists.ConclusionDentists from rural communities were more likely to practice in rural communities than were dental students from urban areas.Practice ImplicationsTo ensure future access to care in rural communities, rural dentists may want to recruit actively or work closely with dental students from rural areas when hiring associates or seeking purchasers for their dental practices.     

Characteristics of dentists participating in capitation and Preferred Provider Organization dental plans

BACKGROUND: In 1998, the American Dental Association Survey Center conducted a telephone and mail survey of U.S. dentists in private practice in an effort to determine the extent of dentists' participation in capitation and preferred provider organization, or PPO, dental plans and the characteristics of dentists who participate in those plans. METHODS: An initial telephone screening survey of a random sample of 11,550 dentists in private practice was conducted to identify dentists who participated in PPO or capitation dental plans. Dentists who participated in either of these plan types then were asked to complete a mail survey on their plan participation. RESULTS: The majority of dentists participating in either type of dental plan reported having never left a dental plan. Dentists who belonged to more than one PPO or capitation plan reported that a larger percentage of their patients were enrolled in these plans and that more of their practice's gross income came from the plans. Participation in PPO and capitation plans has had a positive impact on the practices of many of the responding dentists, particularly with regard to expanding their patient base. CONCLUSIONS: The authors found that the majority of dentists participating in PPO dental plans found it to be a positive experience overall. Dentists participating in capitation plans were less satisfied; more than 50 percent of capitation plan participants reported some level of dissatisfaction with the plans. The majority of dentists participating in a PPO plan expected to renew participation when their current contract expired; a much smaller percentage (though still a majority) of responding capitation-plan participants indicated the same. PRACTICE IMPLICATIONS: Responding dentists' overall indication of satisfaction with their current PPO plan participation probably indicates further growth for these dental plans. On the other hand, capitation plan participants seem much less satisfied with their plans. PPO plans, therefore, seem much more likely to be the type of plan that dentists will choose in the future.     

Treating dental patients who use oral antithrombotic medication: a survey of dentists in the Netherlands

BackgroundFor many years, international guidelines have advised health care professionals not to adjust oral antithrombotic medication (OAM) regimens before invasive dental procedures. The authors conducted a study to examine the opinions of Dutch general dentists regarding the dental care of patients receiving treatment with these medications.MethodsThe authors invited via e-mail 1,442 general dentists in the Netherlands to answer a 20-item Internet-based questionnaire that they developed. Survey items consisted of questions about medical history taking, number of patients in the dental practice receiving OAM therapy, frequency of consulting with medical and dental colleagues and suggested dental treatment of patients during various invasive dental procedures.ResultsA total of 487 questionnaires were returned (response rate of 34 percent). The mean age of respondents was 47 years, and 77 percent were male. The majority of dentists responded that they obtain medical histories, but that they did not know how many of their patients were receiving OAM treatment. Dentists reported that they consult with medical colleagues frequently about antithrombotic medication. Ninety-one percent of respondents stated that they obtained their medical knowledge primarily in dental school. More than 50 percent of the dentists reported that they were not familiar with the international normalized ratio. The majority of dentists responded that they felt a need for clinical practice guidelines.ConclusionsAccording to the results of our survey, most dentists remain cautious when performing invasive dental procedures in patients who are treated with OAMs. Moreover, survey respondents tended to estimate that the risk of bleeding during dental procedures when OAM therapy is continued is higher than the risk of rethrombosis when use of antithrombotic medication is interrupted.Clinical ImplicationsA growing proportion of elderly patients and those with medically complex conditions are being treated in dental practices in the Netherlands. Consequently, more needs to be done to ensure that dentists are offered evidence-based guidance when treating patients who receive OAMs.     

Dental Care for Pregnant Women

BackgroundThe authors conducted a study to examine factors associated with general dentists' provision of care for pregnant women and the extent to which they provide comprehensive dental care.MethodsThe authors mailed an 86-item questionnaire to 1,000 practicing general dentists in North Carolina. Survey domains included provider knowledge about pregnancy and dental health, dental treatment practices, barriers to providing care, outcome expectancy, and personal and practice demographics. The primary dependent variables the authors analyzed were whether dentists provided any treatment to pregnant women and, among those who did, the extent to which they provided comprehensive services. The authors performed multivariate regression analyses to determine factors associated with dentists' provision of care to pregnant women (P < .05).ResultsA total of 513 surveys were returned (a response rate of 51.3 percent), of which 495 surveys had complete responses. The authors included the completed surveys in their analyses. The mean age of the respondents was 46 years. The results of multivariate analysis showed that respondents who perceived a lack of demand for services among pregnant women and provided preconception counseling were less likely to provide any treatment for pregnant patients than were those who perceived a demand for services and who did not provide preconception counseling, respectively. Dentists who were male, had a low knowledge score, provided preconception counseling and treated largely white populations of patients were less likely than female dentists, those who had moderate or high knowledge scores, and those who treated a population of minority patients to provide comprehensive care for pregnant women.ConclusionsMost general dentists in private practice provide care for pregnant women, but the authors found notable gaps in dental provider knowledge and comprehensive dental services available for pregnant women.Clinical ImplicationsAlthough many general dentists provide some dental care to pregnant women, more should be done to ensure that this care is comprehensive.     

Experimental study of two methods of data collection by questionnaire

The aim of the present study was to compare the results obtained using two different methods of data collection about caries preventive services provided in general dental practice. A questionnaire was mailed to a random national sample of 479 dentists resident in Norway in January 1985. The sample was divided into two groups by random allocation. All dentists, irrespective of group, were requested to give background information. One group, comprising 287 dentists (GR), was asked to complete a separate form for every adult patient (greater than or equal to 20 yr) treated in the course of 1 day. The demographic characteristics and dental visiting habits of the patients, as well as the number of teeth present, caries lesions and preventive services rendered were recorded. The other group, 192 dentists (GE), was requested to make general estimates of the time spent on caries prevention and the proportion of patients receiving various types of caries preventive services. The dentists were unaware of the methodologic aspect of the survey and everyone received one reminder in order to guarantee anonymity. The estimation method (GE) did not give the expected advantage over the registration method (GR) in response rate (51.7% vs 46.2%, P greater than 0.40), and gave a gross overestimation of the frequency with which adult patients received different types of caries preventive procedures (P less than 0.005). Thus, even though the estimates of the proportion of total treatment time spent on caries prevention were comparable for the two methods, and the estimation approach is labor-saving, it cannot be recommended for the collection of data on caries prevention in the dental office.     

Assessing Patterns of Restorative and Preventive Care Among Children Enrolled in Medicaid,by Type of Dental Care Provider

BackgroundThe authors investigate the relationship of preventive dental treatment to subsequent receipt of comprehensive treatment among Medicaid-enrolled children.MethodsThe authors analyzed Medicaid dental claims data for 50,485 children residing in Wayne County, Mich. The study sample included children aged 5 through 12 years in 2002 who had been enrolled in Medicaid for at least one month and had had at least one dental visit each year from 2002 through 2005. The authors assessed dental care utilization and treatment patterns cross-sectionally for each year and longitudinally.ResultsAmong the Medicaid-enrolled children in 2002, 42 percent had had one or more dental visits during the year. At least 20 percent of the children with a dental visit in 2002 were treated by providers who billed Medicaid exclusively for diagnostic and preventive (DP) services. Children treated by DP care providers were less likely to receive restorative and/or surgical services than were children who were treated by dentists who provided a comprehensive mix of dental services. The logistic model showed that children who visited a DP-care provider were about 2.5 times less likely to receive restorative or surgical treatments than were children who visited comprehensive-care providers. Older children and African-American children were less likely to receive restorative and surgical treatments from both types of providers.ConclusionsThe study results show that the type of provider is a significant determinant of whether children received comprehensive restorative and surgical services. The results suggest that current policies that support preventive care–only programs may achieve increased access to preventive care for Medicaid-enrolled children in Wayne County, but they do not provide access to adequate comprehensive dental care.
