Caries preventive knowledge and practices among dental hygienists.

PURPOSE: The aim of this study was to determine the knowledge, opinions, and practices of dental hygienists in the areas of dental caries etiology and prevention. METHODS: A pretested, validated 35-question survey instrument was mailed to a one percent national, stratified random sample of dental hygienists in the United States (n = 960) in October 1996. Four complete mailings of the instrument resulted in a 67% response rate, of which 77% were useable (n = 498). Respondents were asked if they agreed or disagreed with statements on caries etiology and preventive procedures, and also asked to rate the effectiveness of procedures for preventing dental caries in children and adults. Data were analyzed using descriptive statistics, t-tests, and ANOVA. RESULTS: Overall level of knowledge of caries etiology and preventive procedures was low. More than 40% of subjects did not recognize that remineralization is the most important mechanism of action of fluoride, and fewer than 50% recognized that dental caries is a chronic infectious disease. Analysis of four factors thought to be related to knowledge and practice showed that younger graduates, more recent graduates, and ADHA members were more knowledgeable about the effectiveness of caries preventive procedures for children (p < .01). Although an overwhelming majority correctly agreed that adults benefit from fluoride and that root caries is an emerging problem, this knowledge was inconsistent with practice (p = .02). Fewer than 35% reported that they provide fluoride to adults of any age, or they wait until the disease is present. For children and adults who did receive fluoride treatments, a one-minute application of an APF gel or foam was most often provided. CONCLUSIONS: Correct information about the etiology and prevention of dental caries is a predisposing factor to making informed decisions. Overall, respondents overrated the effectiveness of flossing and toothbrushing while underrating the effectiveness of fluorides. In the majority of cases, efficiency rather than efficacy was given priority when providing a topical fluoride treatment. An improved understanding of dental caries etiology and the scientific evidence for appropriate caries preventive procedures will allow dental hygienists to prevent and manage this disease better.

Caries conditions among 2-5-year-old immigrant Latino children related to parents' oral health knowledge, opinions and practices.

OBJECTIVES: To collect baseline data prior to initiating a community-based, oral health promotion program in an inner city Latino community in Washington DC, populated by Central American immigrants. METHODS: In 1995, an oral survey of a convenience sample of children 2-5 years of age (n = 142) and a survey of the knowledge, opinions and practices (KOP) of their parents (n = 121) were completed. Clinical data of children were matched with parent respondents of the KOP survey. Data were analyzed for statistical associations using univariate odds ratios, Fisher's exact tests, and multiple logistic regression. RESULTS: Only 53% of the children were caries free. Eighteen percent of all children were in need of immediate dental care and 26% were in need of early or non-urgent dental care. Only 7% of the parents knew the purpose of sealants and 52% knew the purpose of fluorides. Further, only 9% thought that brushing with toothpaste can prevent tooth decay The strongest predictors of dental caries in this population, after adjusting for child's age and mother's education, were recency of mother's residence in the United States and report of an uncooperative child when attempting toothbrushing. CONCLUSIONS: Regimens of caries prevention have been successful in reducing dental decay for a large segment of the US population, yet this disease remains prevalent especially among low socioeconomic groups. The oral health status of the children and the oral health KOP of the parents in this community are disturbingly deficient.

An evaluation of NHANES III estimates of early childhood caries.

OBJECTIVES: The purposes of this study were to estimate and evaluate the prevalence for the United States of early childhood caries (ECC) among children 12 to 23 months of age. METHODS: The 1988-94 National Health and Nutrition Examination Survey (NHANES III) public-use data set was analyzed using SUDAAN. Two ECC case definitions were used. Definition #1 was restricted to the caries score called by the examiner. Definition #2 liberally included children identified by definition #1 and those possibly having questionable caries scores. RESULTS: The NHANES III six-year prevalence estimates of caries in the maxillary anterior incisors of children 12 to 23 months of age were 1.0 percent for definition #1 and 1.7 percent for definition #2. Mexican-American and economically disadvantaged children were disproportionally represented with ECC. CONCLUSIONS: The prevalence of ECC among children 12 to 23 months of age is barely detectable at the national level. Alternative study designs and improved case definitions are needed for further advances in ECC.

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.

An assessment of oral cancer prevention curricula in U.S. medical schools.

BACKGROUND: Oral cancer is readily detectable through routine examination, but five-year survival rates remain low. Physicians bear the same responsibilities as dentists in the early detection of oral cancers, because high-risk patients utilize medical services more often than dental services. METHODS: Because physicians' practices are largely influenced by their training, this study assessed the level of oral cancer education provided to undergraduate U.S. medical students. Health history and physical diagnosis course curricula were assessed for relevant content. RESULTS: The response rate from the U.S. medical schools was 63.2%. When compared with the "gold standard," the average score was 43% of the optimum. Seven percent of the schools did not require inspection of the mouth, 29% required inspection of all oral structures, and intraoral palpation was advocated by 43% of the schools. Although most schools included questions about alcohol and tobacco use, only 13% asked about sunlight exposure. CONCLUSION: Preliminary oral cancer training in medical schools regarding physical assessment and elicitation of signs, symptoms, and high-risk behaviors lacks both adequacy and comprehensiveness.

Korean dental hygienists' knowledge and opinions about etiology and prevention of dental caries.

OBJECTIVES: Because of their formal education Korean dental hygienists have the potential to be the primary source of information on caries prevention for patients and the general public, and influence the use and adoption of caries preventive procedures. The purposes of this study were to determine the knowledge and opinions about caries etiology and prevention among Korean dental hygienists, and to describe associated factors. METHODS: A pre-tested, 20-item questionnaire was mailed to 1120 dental hygienists selected by stratified random sampling and allocated proportionately. A postcard reminder was sent to all dental hygienists after 1 week. Non-respondents were sent additional complete mailings after 3 and 7 weeks. The response rate was 77% (n=863). RESULTS: Analysis of six factors thought to be related to knowledge about caries etiology and prevention showed that dental hygienists who were taught to provide oral health education and believe that it is desirable to practice oral health education during dental hygiene school and those employed in health centers were likely to be more knowledgeable about caries etiology and prevention than other hygienists (P<0.05). In regression analysis of the perceived effectiveness of caries preventive procedures, hygienists who provided oral health education during their formal training tended to rate caries preventive procedures as being more effective than other dental hygienists (P<0.05). CONCLUSIONS: Overall, the results of this study suggest that most dental hygienists do not have up-to-date information on the etiology and prevention of dental caries, mechanisms of action of fluoride and effectiveness of preventive procedures. Efforts to increase the level of knowledge of Korean dental hygienists about caries prevention should focus on strategies to educate dental hygienists who have not been taught to provide oral health education, who do not have favorable opinions about the desirability of oral health education, and who had no experience with providing oral health education as part of their work, especially hygienists working in private clinics. Further, these efforts should include the revision of dental hygiene curricula and continuing education courses.

Response to Weinstein: public health issues in early childhood caries.

Dr Weinstein's thoughtful overview of public health issues in early childhood caries (ECC) provides an excellent basis for further exploration. For public health to focus on a given problem several factors must be addressed: the disease must be widespread; the etiology or the prevention of the disease or condition must be known; this knowledge is not being applied; and resources for interventions must be available. Currently, appropriate data are not available for ECC and the problem is exacerbated because there is no case definition for the disease. Therefore it is difficult to make public health policy to address this disease. With the knowledge of case definition, prevalence, and efficacy of treatment, we are more likely to engender interest and funding for ECC. Studies in other countries have demonstrated that children who are malnourished, have low birth-weight or both, likely will have hypomineralized primary teeth and thus at risk of ECC. Low birth-weight infants (less than 2500 g) currently constitute over 7% of all US births. The impact of low birth-weight on oral health is not known. Weinstein favors the use of operator-applied preventive agents, yet little evidence is available on the safety and effectiveness of these agents among infants and young children. Further, they are unlikely to be cost-effective and they require frequent appointments, which is often difficult for poor families to manage. Community interventions hold the greatest promise for preventing ECC because larger numbers of people can be reached than in private practice clinical settings.

Maryland veterans' knowledge of risk factors for and signs of oral cancers and their use of dental services.

OBJECTIVES: The purpose of this study was to evaluate outpatient veteran'í knowledge about risk factors for and signs of oral cancers, and their utilization of dental services. DESIGN: Patients receiving primary health care services were surveyed during August 1997. SETTING: Primary health care services at three medical centres within the VA Maryland Health Care System (VAMHCS). SUBJECTS: A total of 135 outpatient veterans were interviewed. INTERVENTION: Questionnaire administered by trained interviewers. MAIN OUTCOME MEASURES: Fifteen percent of the sample were eligible for dental care at the VA, while over 40% of those veterans participating in the study were unaware of their VA eligibility for dental services. Fifty six percent of the total sample received dental services from a private dentist, while 13% reported they had no provider of dental care. Of those not eligible for dental care at the VA (n = 115), the majority (67%) received dental care from a private dentist. Current use of tobacco and alcohol was reported by 27% of the sample. Nonsmokers were more likely to visit the dentist in the previous year than smokers (OR = 2.39, 95% C.I. 1.11,5.12). Although 84% correctly identified tobacco use as a risk factor, only 39% correctly identified regular alcohol use as a risk factor. CONCLUSIONS: Veterans at higher risk for oral cancers were less likely to have visited the dentist in the previous year, and, overall, were ill informed and misinformed about these cancers.

National survey of Korean dentists' knowledge and opinions: dental caries etiology and prevention.

OBJECTIVE: 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). CONCLUSIONS: 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.

Maryland adults' knowledge of oral cancer and having oral cancer examinations.

OBJECTIVES: This study sought to determine (1) knowledge of risk factors for oral cancer, (2) knowledge of signs and symptoms of oral cancers, and (3) factors associated with having had an oral cancer examination among 916 Maryland adults 18 years of age and older. METHODS: A statewide, random-digit dial, computer-assisted telephone survey was conducted. The pretested instrument consisted of 32 questions that required 12 minutes to complete. RESULTS: Overall, level of knowledge about risk factors for and signs and symptoms of oral cancers was low; misinformation was high. Although 85 percent reported hearing about oral or mouth cancer, only 28 percent of the respondents reported having had an oral cancer examination. Of these, 20 percent had the exam during the past year--the recommended frequency for persons 40 years of age or older. In logistic regression analysis, adults more likely to have had an oral cancer examination included those who thought personal behavior causes more cancer than environmental factors; had more knowledge about risk factors for oral cancer; and were 40-64 years of age, white, and better educated than their counterparts (P < .05). The primary reasons for not having an exam were "no reason/didn't know I should" and "doctor/dentist didn't recommend." CONCLUSIONS: These results demonstrate a need for interventions designed to increase knowledge levels of risk factors for, signs, and symptoms of oral cancers and the need for oral cancer examinations; and to increase oral cancer examinations.

Knowledge, opinions and practices of general dentists regarding oral cancer: a pilot survey.

The authors mailed a pilot survey to 500 randomly selected general dentists. Although most dentists reported their knowledge of oral cancer to be current, their actual knowledge of oral cancer risk factors and signs and symptoms was inconsistent. Conflicting data were also found between their level of knowledge and their provision of oral cancer examinations. Most respondents agreed that patients should undergo an oral cancer examination annually, yet many do not provide this service.

Scientific progress in understanding oral and pharyngeal cancers.

Oral and pharyngeal cancers result from a complex interaction between genetic susceptibility and behavioral factors. Improved understanding of the underlying genetic events has led to insights about how oral and pharyngeal cancers develop and suggests promising new treatments. Tobacco and alcohol consumption are associated with most oral and pharyngeal cancers. Dental professionals' efforts to modify their patients' tobacco and alcohol use and to detect oral lesions at an early stage, together with scientific advances, will help reduce the impact of these cancers.

Coverage and quality of oral cancer information in the popular press: 1987-98.

OBJECTIVES: National data show a lack of knowledge and misinformation about oral cancer and its early detection among the general public. A major source of health information is the popular press. For that reason this study reviewed coverage and quality of news items on the topic of oral cancer in the popular press. In addition, the number and types of tobacco advertisements in women and men's magazines were recorded for a one-year period. METHODS: Articles from magazines and newspapers were retrieved from the Magazine Index (1987 to April 1998), Newspaper Abstract (1989 to April 1998) and the Health & Wellness (1987 to April 1998) databases. The articles were analyzed both for adequacy of content and information. RESULTS: A total of 50 articles and news items including oral cancer were identified and analyzed, 18 from newspapers and 32 from magazines. Ninety-four percent of the articles mentioned at least one risk factor for oral cancer. More than half of the articles (56%) identified spit tobacco (chewing tobacco or snuff) as the major risk factor for oral cancer, while far fewer mentioned either cigarettes (32%) or cigars (12%). Over 50 percent of the articles did not mention warning signs for oral cancers. Fourteen percent suggested clinical oral cancer examinations by a health professional; only 8 percent advised the use of self-examination. A total of 417 tobacco advertisements (482 pages) were found among 22 magazines for the one-year period. They included 410 cigarette ads, seven cigar ads, and no spit tobacco ads. CONCLUSIONS: This study demonstrates the lack of coverage about oral cancer in the popular press in the past decade and provides a partial explanation of the public's lack of knowledge and misinformation about oral cancers.

Reducing the burden of oral and pharyngeal cancers.

In the United States, oral and pharyngeal cancers continue to result in significant morbidity and mortality. Dental professionals play a pivotal role in all facets of controlling the burden of oral and pharyngeal cancer-from efforts to prevent its occurrence, to ensuring that oral cancers are detected at the earliest possible stage, to treating these cancers, and to ensuring maximum quality of life and function for oral and pharyngeal cancer survivors. Individually and by making linkages within the community and beyond, dentists can help patients modify their risk of these cancers and can take steps to screen for them, thereby potentially improving survival and function of those who develop oral cancer. Creative partnerships between community dentists and academic and other research centers will help move knowledge of the biological processes involved in carcinogenesis and innovations in treatment into clinical practice. Partnerships between dental and medical professionals may also help efforts to reduce the morbidity related to oral and pharyngeal cancers. Local, state and national multidisciplinary initiatives are emerging that focus more broadly on risk factor control or oral and pharyngeal cancer issues. These many forms of cooperative approaches offer excellent opportunities to make a significant impact on reducing the incidence of and in treating these debilitating and disfiguring malignancies.

Introduction to the symposium on minimal intervention techniques for caries.

Although dental caries has declined precipitously in many industrialized countries, this disease has escalated in less developed countries. Moreover, dental caries remains a public health problem even in most industrialized countries because the disease frequently is more prevalent among subpopulations without access to preventive regimens and treatment. In some developing countries where dental facilities and providers are rare, alternative measures for managing frank lesions are being used. One example of these minimal intervention techniques is "Atraumatic Restorative Treatment" (ART). This procedure, endorsed and actively promoted by the World Health Organization, requires no anesthetic and its costs are minimal. This symposium addresses several aspects and issues of minimal intervention techniques for caries management.

The need for health promotion in oral cancer prevention and early detection.

OBJECTIVES: This review paper provides a rationale for using health promotion to help reduce morbidity and mortality due to oral cancers by identifying barriers to prevention and early detection of these cancers and discussing strategies for change. METHODS: A literature review of the following areas was conducted: epidemiology of and risk factors for oral cancers; knowledge, opinions, and practices of health care providers and the public regarding prevention, early detection, and control of oral cancers; and policies and regulations that either enhance or act as barriers to the prevention and early detection of oral cancers. RESULTS: Overall, the public is ill-informed about risk factors for and signs and symptoms of oral cancers and relatively few US adults have had an oral cancer examination. Further, health care providers are remiss in providing oral cancer examinations and detecting early oral cancers. CONCLUSIONS: To achieve the 13 oral cancer objectives contained in "Healthy People 2000," health care providers and the public must know the risk factors for these cancers as well as their signs and symptoms. Further, health care providers need to provide oral cancer examinations routinely and competently. Equally important, the public needs to know that an examination for oral cancer is available and that they can request one routinely. Thus, a vigorous agenda that includes education, policy, and research initiatives is needed to enhance oral cancer prevention and early detection.
