Opinions about oral cancer prevention and early detection among dentists practising along the Texas–Mexico border

OBJECTIVES: The purpose of this study was to assess dentists' opinions about oral cancer (OC) prevention and early detection. METHODS: Data were collected by a self-administered mail questionnaire sent to all 398 registered dentists practising along the Texas-Mexico border. RESULTS: The effective response rate to the survey was 40%. While 90% of respondents agreed that oral cancer examinations (OCE) should be provided annually for patients 40 years of age and older, only 59% of respondents believed their OC knowledge was current. While 99% agreed that dentists were qualified to perform OCE, only 54 and 68% respectively, agreed that dental hygienists and physicians were similarly qualified. Dentists who rated their undergraduate OC training favorably (OR = 2.68, 1.23-5.81, P = 0.011), had attended their last oral cancer continuing education (OCCE) course within the past 5 years (OR = 2.46, 1.25-4.86, P = 0.009), and those who performed OCE on all patients 40 years and older (OR = 2.64, 1.32-5.26, P = 0.005), were more likely to agree their OC knowledge was current. CONCLUSIONS: Respondents expressed diverse opinions about OC prevention and early detection. Positive opinion on currency of OC knowledge was associated with performance of OCE. Results indicate a need for OCCE targeting the study population as well as increased emphasis on OC curriculum in dental schools.
