Oral and pharyngeal cancer: knowledge and opinions of dentists in British Columbia and Nova Scotia.
Oral and pharyngeal cancers are largely preventable and can be successfully treated when diagnosed at an early stage. Dentists in British Columbia and Nova Scotia were surveyed regarding their knowledge and opinions about oral and pharyngeal cancer. In February 1998 a pretested 41-item survey was mailed to a random sample of dentists in British Columbia and the population of dentists in Nova Scotia. A reminder postcard and one additional mailing were sent to nonrespondents. Of the 670 dentists supplying usable responses (response rate 55.2%) only 56.7% agreed that their knowledge of the subject was current. Most dentists correctly identified tobacco use (99.4%) and alcohol use (90.4%) as risk factors, but fewer correctly identified factors such as the use of spicy foods (57.0%) and poor oral hygiene (46.3%) as not being risk factors. Only 42.5% identified both erythroplakia and leukoplakia, in that order, as the conditions most likely associated with oral cancer. Indices of risk and diagnostic knowledge were constructed by summing the number of correct responses to items in each domain. On 16 risk factors the mean correct score was 9.2, and on 14 diagnostic procedures the mean correct score was 10.0. Only 38.5% of dentists had consistent levels of knowledge on both indices. Differences between the provinces were statistically significant (p < 0.01) for only 2 knowledge items. About three-quarters of all dentists (77.0%) were interested in taking continuing education courses. Dentists in British Columbia and Nova Scotia could benefit from undergraduate and continuing education courses to increase their knowledge of risk and diagnostic factors for oral cancer.
Oral and pharyngeal cancer: practices and opinions of dentists in British Columbia and Nova Scotia.
Oral and pharyngeal cancers are associated with high mortality rates, a situation usually attributed to late-stage diagnosis. Dentists in British Columbia and Nova Scotia were surveyed regarding their practices and opinions related to oral and pharyngeal cancer. In February 1998 a pretested, 41-item survey was mailed to a random sample of dentists in British Columbia (n = 817) and the population of dentists in Nova Scotia (N = 423). A reminder postcard and one additional mailing were sent to nonrespondents. Of the 670 dentists supplying usable responses (response rate 55.2%), only 56.7% agreed that their knowledge of the subject was current. Of 8 health history items, dentists assessed 5 on average, with most (88.0%) asking about the patients' current use of tobacco. A total of 72.7% of the responding dentists performed an oral cancer examination for all edentulous patients at every appointment, but 10.9% never did so. Similarly, 70.7% of the dentists always provided an oral cancer examination at the initial appointment for patients 40 years of age and older, but 9.8% never did so. Undergraduate training related to oral cancer examination was reported as good by only 52.2% of the dentists. About three-quarters of all dentists (77.0%) were interested in taking continuing education courses on this subject. Differences between the 2 provinces were not statistically significant (p > 0.01). Dentists in British Columbia and Nova Scotia could benefit from undergraduate and continuing education courses to increase their knowledge of health history assessment, examination for oral and pharyngeal cancers, and risk reduction strategies, such as counselling about tobacco cessation.
Attitudes of pediatric dentists towards tobacco intervention for children and adolescents: a pilot survey.
PURPOSE: The purpose of this study was to obtain pilot information concerning the attitudes of pediatric dentists regarding their role in tobacco intervention for children and adolescent patients. METHODS: A 1-page survey, which was adapted and pretested from a previous, comprehensive survey, was distributed to all registrants at the 2001 American Academy of Pediatric Dentistry Annual Meeting in Atlanta, Ga. Descriptive and exploratory multivariable techniques were used to analyze the data. RESULTS: Of the 173 respondents, only 18% had ever received training in tobacco cessation counseling. Although most dentists agreed that they should play a role in tobacco intervention with their young patients, the majority was not comfortable with this task. Pediatric dentists with tobacco counseling training were more likely to accept their role in tobacco prevention and cessation efforts and were more confident in their ability to do so than were their counterparts. Pediatric dentists consider tobacco cessation an important role in their practices, but do not consider themselves well prepared to act on this responsibility. CONCLUSIONS: The results of this pilot survey strongly suggest that a similar, national, comprehensive study should be conducted among pediatric dentists.
