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.
