Caries-preventive methods used for children and adolescents in Denmark, Iceland, Norway and Sweden

Denmark, Iceland, Norway, and Sweden have all had a similar decline in dental caries during the last 20 years, although the decline has come later in Iceland. The purpose of this study was to compare the caries-preventive methods used for children and adolescents in these four countries. Questionnaires were sent to random samples of dentists, dental hygienists, and dental nurses working with children during 1995 and 1996. The results showed that the use of preventive methods was generally consistent between the countries. Nevertheless there were differences between the countries concerning the choice of preventive strategy for risk patients and also in how prevention was implemented. Danish dental care providers chose oral hygiene education as the priority, which they put into practice. Apart from fluoride varnish for some patients, most of them did not use or recommend fluoride except fluoride toothpaste. The Norwegian and Icelandic dental care providers chose both oral hygiene education and the use of fluoride as priorities, while most Swedish dental care providers preferred to provide dietary advice and oral hygiene education, and additional fluoride for risk patients. The differences could not be explained by other variables than nationality, implying that there are differences between the dental cultures in the four countries. The informational basis of decisions on preventive strategies varied between the different dental professionals in each country as well as between the countries, indicating that national professional cultures are being shaped differently. Despite the differences in choice of preventive methods, the dental health of children varies little across the frontiers. This raises the question of the significance of the choice of preventive methods to the decline of dental caries and points towards an urgent need to develop evidence-based preventive strategies.     

Knowledge and use of fluoride among Indiana dental professionals

OBJECTIVES: This study assessed the knowledge of Indiana dentists and dental hygienists about fluoride's predominant mode of action and their protocols for the use of fluoride for dental caries prevention. METHODS: In 2000, questionnaires were mailed to 6,681 Indiana dentists and hygienists prior to the 2001 release of recommendations for the use of fluoride by the US Centers for Disease Control and Prevention. In 2005, the questionnaires were again sent to Indiana dental professionals to assess changes in knowledge and protocols. In addition, a 10 percent sample of Illinois dentists and hygienists were surveyed to determine the similarity of Indiana and Illinois responses. RESULTS: Questionnaires were anonymously completed and returned. In 2000, a minority of Indiana health professionals (17 percent) correctly identified that remineralization was fluoride's predominant mode of action. There was a significant increase in Indiana respondents correctly identifying this predominant mode of action between 2000 and 2005 (17 percent versus 25 percent, respectively, P < 0.0001). Fourteen percent of Illinois respondents answered correctly in 2005. Preeruptive incorporation of fluoride into enamel was the most frequently cited incorrect response (IN 2000, 79 percent; IN 2005, 71 percent; IL 2005, 82 percent). Some protocols for use of fluoride products reflected inadequate understanding of fluoride's predominant posteruptive mode of action. CONCLUSIONS: The majority of dental professionals surveyed were unaware of the current understanding of fluoride's predominant posteruptive mode of action through remineralization of incipient carious lesions. Additional research is indicated to assess fluoride knowledge and protocols of dental professionals nationwide. Educational efforts are needed to promote the appropriate use of fluoride.     

Smoking cessation as a dental intervention--views of the profession

OBJECTIVE: To undertake a questionnaire-based survey to determine the attitudes and activities of dental professionals in primary care in the Northern Deanery of the UK in relation to providing smoking cessation advice. METHODS: Questionnaires for dentists, hygienists and dental nurses were sent to hygienists to distribute to other members of the team. The information collected included: smoking status of the professionals and the practice; roles of the dental team in giving smoking cessation advice; levels of training received; and potential barriers to giving this brief intervention. RESULTS: Over 90% of practices were smoke-free environments and significantly more dental nurses (23%) were smokers compared to dentists (10%) and hygienists (7%) (p<0.01). The majority of dentists and hygienists enquired about smoking status of their patients and all three groups believed that hygienists and dentists should offer brief smoking cessation advice. Potential barriers to delivering smoking cessation advice were identified: lack of remuneration; lack of time; and lack of training. CONCLUSION: Dental teams in primary care are aware of the importance of offering smoking cessation advice and, with further training and appropriate remuneration, could guide many of their patients who smoke to successful quit attempts.     

Knowledge, Attitude and use of Fluorides among Dentists in Texas

Aim: The centers for disease control and prevention (CDC) recommendations on fluoride use were published in 2001. This study examines how this information has diffused to practicing dentists and the level of fluoride knowledge and use among Texas dentists. Materials and methods: A questionnaire was sent to dentists who self-identified as being in pediatric (343), dental public health (72), and general practices (980); a 12% sample of registered dentists in Texas. Results: Response rate was 42.9%. About 90% of surveyed dentists reported using fluorides routinely. Only 18.8% reported fluoride varnish as the topical fluoride most often used. About 57% incorrectly identified primary effect of fluoride. 'Makes enamel stronger while tooth is developing prior to eruption' was the most commonly cited wrong answer (44%). Only 5% identified that posteruptive effect exceeds any preeruptive effect. Conclusion: Despite the evidence for fluoride varnish preventing and controlling dental caries being Grade I, its use is still uncommon. Dentists are expected to be knowledgeable about products they use, but this study reflects lack of understanding about fluoride's predominant mode of action. More accurate understanding enables dentists to make informed and appropriate judgment on treatment options and effective use of fluoride based on risk assessment of dental caries. Clinical significance: Lack of knowledge of, or failure of adherence to evidence based guidelines in caries prevention by use of appropriate fluoride regimens may adversely affect caries incidence in the population.

Preventing and detecting oral cancer. Oral health care providers' readiness to provide health behavior counseling and oral cancer examinations

BACKGROUND: The authors conducted a study to examine oral cancer prevention and early detection practice patterns in a population-based random sample of practicing oral health care professionals in New York state. METHODS: The authors surveyed a population-based, self-weighting, stratified random sample of dentists (n = 1,025) and dental hygienists (n = 1,025) in New York state. They assessed the subjects' readiness to offer tobacco-use cessation and alcohol-abuse counseling and oral cancer examinations. RESULTS: The effective response rates were 55 and 66 percent for dentists and dental hygienists, respectively. In terms of readiness to perform oral cancer examinations for patients aged 40 years and older, the large majority (82 percent of dentists and 72 percent of dental hygienists) were in the maintenance stage of behavior, indicating that oral cancer examinations were a routine part of their practice. In terms of readiness to offer tobacco-use cessation counseling, only 12 percent of dentists and 21 percent of dental hygienists were in the maintenance stage, and only 2 percent of dentists and 4 percent of dental hygienists were in the maintenance stage of offering alcohol-abuse counseling. CONCLUSIONS: Oral cancer examinations seem to have been adopted as a standard of practice by most oral health care providers in New York state, but cancer prevention services, such as counseling regarding cessation of tobacco use and alcohol abuse, are lacking. CLINICAL IMPLICATIONS: Oral health care providers should be trained in oral cancer prevention services such as tobacco-use cessation and alcohol-abuse counseling and encouraged to include these services, along with continued provision of oral cancer examinations, as a standard aspect of care.     

Challenges of and strategies for changing prescribing practices of health care providers

Problems related to inappropriate prescribing practices of physicians in general are well recognized. Dietary fluoride supplements have been implicated as one of the contributing factors in an increase in dental fluorosis. Inappropriate prescribing practices of providers have been cited as a major factor in this implication. Numerous studies of physicians and dentists have documented a lack of knowledge and inappropriate prescribing practices regarding fluoride supplements. The purpose of this paper is to identify barriers to changing fluoride-prescribing practices of health care providers and to suggest strategies for implementing change. To increase optimal and appropriate use of fluoride supplements, educational interventions are necessary for all user groups--detail men and women, physicians, dentists, pharmacists, nurse practitioners, dental hygienists, and the public. In addition, environmental supports for the educational activities in the form of policy, regulation, standards of care, and guidelines are recommended for consideration.     

Dental Hygienists in Nontraditional Settings: Practice and Patient Characteristics

The dental hygienist's role in the treatment of special populations in nontraditional settings is an important one. Little is known about the hygienist's practice characteristics in these settings, nor about the patients receiving care. To gain needed information, a representative sample of the entire population of licensed hygienists in the United States was screened (n = 38,380). This screening identified 1,205 hygienists practicing in nontraditional settings. These hygienists were sent comprehensive questionnaires examining practice and patient characteristics. Completed questionnaires were returned by 1,016 (84.3%) hygienists. This report describes reported hygiene practice characteristics; hygienist interactions with patients and providers; and patient characteristics, including age, medical/emotional/social conditions, and dental treatment needs. Major findings of respondents' reports reveal that: approximately 90 percent of patients were in need of dental/dental hygiene services with approximately one in four requiring only dental hygiene services; the dental hygienists perceived a high level of acceptance of their role by patients and providers; the majority of patients treated were categorized as generally medically healthy (65.7%); and the clinical practice of dental hygiene in nontraditional settings mirrors that of private practice.     

Attitudes to independent dental hygiene practice: dentists and dental hygienists in Ontario

This study examined Ontario dentists' and dental hygienists' attitudes to independent dental hygiene practice and changing the scope of practice. Data were collected from a mail survey of a systematic, stratified sample of Ontario dentists (483 respondents) and dental hygienists (437 respondents) conducted in the winter and spring of 2002 to assess what practising dentists and dental hygienists think about independent practice and other professional issues. Contrary to previous research, this study found that male and female dentists did not differ in their attitudes to independent dental hygiene practice and university education for dental hygienists: both strongly opposed the former and tended to support the latter. Similarly, few differences in attitude amongst dentists by specialty were found. Dental hygienists were generally supportive of independent practice and of expanding their scope of practice. On some measures, however, sex and age differences in attitudes were evident: at times dental hygienists who were older or male seemed to be stronger advocates for professional change than others.     

Knowledge and professional experiences concerning child abuse: an analysis of provider and student responses

PURPOSE: The objective of this study was to explore dentists', dental hygienists', dental students', and dental hygiene students' knowledge about their professional responsibilities concerning suspected child abuse and their professional experiences with this issue. METHODS: Questionnaire data were collected from 220 general dentists, 158 dental hygienists, 233 dental, and 76 dental hygiene students regarding their knowledge, professional responsibilities, and behavior concerning child abuse. RESULTS: Twenty percent of the dentists and 9% of the dental hygienists had reported at least 1 case of suspected child abuse. While 83% of the dental professionals knew that they had to report suspected cases of child abuse, only 73% of the students knew their legal responsibility. Also, only 28% of the professionals and 18% of the students knew where to report suspected child abuse. Compared to students, professionals had more knowledge concerning the diagnosis of child abuse, while students were more knowledgeable concerning signs of sexual abuse. Professionals, however, were less likely to know that failure to report suspected abuse was a misdemeanor. CONCLUSION: These data showed that not all dental care providers and students were prepared to fulfill their legal and professional responsibilities in these situations.     

Caries preventive methods in child dental care reported by dental hygienists, Norway, 1995 and 2004

Dental hygienists are used as first-line personnel in child dental care in Norway, and have an increasing influence on the delivery of preventive dental services. The purpose of this study was to describe: (1) preventive methods reported by hygienists in child dental care in Norway and (2) changes in preventive care during the 9-year period 1995 to 2004. Questionnaires were sent to all dental hygienists in the public dental services in Norway in 1995 and 2004; 70% (199 of 286) were returned in 1995 and 71% (210 of 297) in 2004. The hygienists considered one-third of children to be at risk of caries and spent 45 min of preventive care on these children every 16th month, while the remaining children were given 15 min of prevention every 20th month. One-third of the hygienists provided fluoride varnish for all children and one-fourth placed sealants routinely. Ninety percent of the hygienists reported that all children were given information on diet, hygiene, and fluoride. Most of the preventive practices of dental hygienists reflected limited changes in the period 1995 to 2004. However, the hygienists had reduced the use of fluoride varnishes and less often recommended fluoride tablets. The majority of hygienists reported that they individualized clinical prevention, while individual oral health information was standardized and given to all children. The results indicate that in 2004 a preventive approach combining individual information for all with intensified clinical prevention for children considered at risk was followed in child dental care.

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.     

Prevention of early childhood caries in North Carolina medical practices: implications for research and practice

Early childhood caries is a significant public health problem in low-income children, with important negative consequences for the child and the family. The purpose of this paper is to describe the development, implementation, and preliminary outcomes of preventive dentistry programs in North Carolina that target low-income children from birth to thirty-five months of age. The focus is on Into the Mouths of Babes, a statewide program in which pediatricians, family physicians, and providers in community health clinics are reimbursed by Medicaid to provide preventive dental services for children (risk assessment, screening, referral, fluoride varnish application) and caregivers (counseling). The provider intervention includes continuing medical education lectures and interactive sessions, practice guidelines for the patient interventions, case-based problems, practical strategies for implementation, a toolkit with resource materials, and follow-up training. In the first two years of the statewide program, 1,595 medical providers have been trained. The number of providers billing for these services has steadily increased, and by the last quarter of 2002, the number of visits in which preventive dental services were provided in medical offices reached 10,875. A total of 38,056 preventive dental visits occurred in medical offices in 2002. By the end of 2002, only sixteen of the state's one hundred counties had no pediatrician, family physician, or local health department participating. The preliminary results from this program demonstrate that nondental professionals can integrate preventive dental services into their practices. The program has increased access to preventive dental services for young Medicaid children whose access to dentists is restricted. Assessments of effectiveness and cost-effectiveness of both the provider and patient interventions are under way.     

A qualitative study of limited access permit dental hygienists in Oregon

Many states have adopted alternative oral health care delivery systems that include expanded roles for dental hygienists. This qualitative study was designed to evaluate the impact of the Limited Access Permit (LAP) legislation in Oregon and to understand the relationship between dental hygienists and dentists within this delivery system. The snowball sampling technique was used to identify LAP dental hygienists and collaborating dentists. The snowball sampling technique begins with the identification of a known expert in the field who serves as the initial "sampling unit." Subsequent individuals are then recommended, or nominated, to the investigator by the initial study participant and are selected based upon the need to fill in or extend information. The final sample consisted of seven LAP dental hygienists and two collaborating dentists. Interviews, field observations, and document analysis were utilized for data collection. Factors that led to the creation of LAP dental hygiene practice, current LAP practice, personal characteristics, relationships between LAP dental hygienists and dentists, and the impact that LAP dental hygienists have had on access to oral health care were explored. Data revealed that the Oregon legislature twice expanded the LAP scope of practice to increase access to oral health care services. LAP dental hygienists practice in community and school-based settings. Common characteristics of LAP dental hygienists include entrepreneurship, lifelong learning, and a commitment to underserved populations. The findings from this study indicate that LAP dental hygienists and collaborating dentists have positive relationships. No evidence of lower quality of care in unsupervised dental hygiene practices was found. However, the impact of the LAP legislation is still unknown due to the limited numbers of LAP dental hygienists and the early nature of the LAP practice.     

Dental Sealant Usage in Virginia

This trend study reports the results of a survey designed to determine usage of dental sealants in Virginia. A total of 2,434 general dentists, dental hygienists, and pedodontists were sent questionnaires regarding usage, technics, products, educational experience, and public interest in dental sealants. Increases in the provision of sealant coverage and in public interest for this preventive measure were noted. Approximately three-fourths of general dentists and dental hygienists working in a general or pedodontic practice are offering sealants to their patients. Pedodontists are the largest group of providers, with nearly 100 percent of pedodontists applying sealants. Recent graduates are applying sealants more often than earlier graduates. Preference for Delton clear color, light-cured material was shown. In general, a lack of professional knowledge about sealants continues to exist. Professional organizations and academic institutions may want to plan additional continuing education offerings for practitioners and to consider increased dental education instruction for students.     

Business orientation and the willingness to distribute dental tasks of Dutch dentists

AIM: Dentists have a dual professional role: they have to focus on good oral health in their patients and, at the same time, they have to organise their practices. The aim of this analysis was to assess the extent to which dentists can be seen as business-oriented and/or willing to delegate to dental team members and others, and to investigate which personal and practice characteristics of dentists can be regarded as determinants for these two aspects of their professional role. METHOD: The data were collected in 2000 by means of a written questionnaire sent to a random stratified sample of 790 dentists. RESULTS: 607 (77 per cent) dentists responded. Multivariate regression analysis showed that business oriented dentists distinguish themselves by having larger practices and a higher level of professional satisfaction. Furthermore, although to a lesser extent, on a regular basis, they treat patients from colleagues in the practice. There are proportionately fewer women dentists in this category. Dentists oriented on task distribution can also be typified by working in larger practices, but in addition they have a greater preventive treatment philosophy and have more hours of support provided by oral hygienists. CONCLUSION: Among Dutch dentists there exist clear differences in the way they take on their role as dentists with regard to business orientation and their willingness to distribute dental tasks.     

Differences in Characteristics of California Dentists Who Employ Dental Hygienists and Those Who Do Not

BackgroundDental hygienists can increase dentists’ productivity, yet nationwide, one-third of dentists do not employ a hygienist. The profession needs more information on the characteristics of these dentists and their reasons for not employing hygienists.MethodsThe author used a 2003 survey of California dentists and a logistic regression analysis to assess factors independently associated with dentists’ employment of hygienists. These factors included dentists’ personal, practice, population, productivity and patient care characteristics. She also assessed characteristics of dentists who did not employ hygienists and their reasons for not doing so.ResultsDentists who worked full time, employed more administrative personnel, had more operatories, had longer appointments, had more income from private payers and had more elderly patients were more likely to employ hygienists than were dentists with alternative characteristics. Graduates of dental schools outside the United States and those with fewer white patients were less likely to employ hygienists. Reasons for not employing hygienists included personal choice, high costs and not having a sufficient volume of work.ConclusionsThe author's findings suggested that in employing hygienists, dentists consider preferences, practice income and patient demand, among other factors. Further examination of reasons for employing hygienists is warranted.Practice ImplicationsHiring a hygienist increases a dental practice's patient capacity, yet not all dentists can or choose to do so. Policies aimed at increasing dental workforce capacity must take into account dentists’ characteristics and preferences.     

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

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

Task division between dentists and dental hygienists in Norway

Abstract – Objective: The aim of the study was to investigate the attitudes among dentists and dental hygienists to the policy objective in Norway of delegating more dental work from dentists to dental hygienists. Method: A questionnaire was mailed to a random sample of 1111 dentists and 268 dental hygienists in 2005. The response rates were 45% (504) among the dentists and 42% (112) among the dental hygienists. The survey sought to explore any discrepancies between current and preferred mix of different work tasks, as well as attitudes to the idea of substituting dentists with dental hygienists for certain work tasks. Logistic regression was used to analyse how answers differed by respondent characteristics. Results: Dentists spent only half of their total working hours on complex dental services, i.e. tasks that only dentists are skilled to undertake. Nearly 40% of their time was spent on tasks that dental hygienists are qualified to perform; examinations, screening and basic treatments. Still, the mix of work tasks that dentists preferred would involve slight changes: on average only 2% points more complex treatment and 3–4% points less of those tasks that dental hygienists are permitted to provide. Seemingly contrary, as many as 60% of dentists answered that it was ‘desirable to delegate’ more tasks to dental hygienist. However, only 21% of the dentists agreed that dental hygienists should be the entry point for dental services. Dental hygienists would prefer to do relatively more basic treatments and fewer examinations and screening, and the vast majority among them supported the idea that they could be the entry point for dental services. Conclusion: The results suggest that there will not be major changes in the division of labour between dentists and dental hygienists in Norway, if dentists are to be held responsible for taking such initiatives. Although dentists agree that more of their current work could– in principle – be delegated to dental hygienists, they do not prefer to reduce much of their own current activity of those work tasks that dental hygienists are qualified to perform.
