Oral cancer: Knowledge, practices and opinions of dentists in Yemen

Background: Oral cancer presents with high mortality rates, and the likelihood of survival is remarkably superior when detected early. Dental professionals have an important role and responsibility in prevention and early detection of oral cancer. Purpose: The aim of this study was to assess the knowledge, practices and opinions regarding oral cancer among dentists in Yemen. Materials and Methods: A cross-sectional survey was conducted using a self-administered questionnaire involving private and public dental practitioners, working in different governorates in Yemen. Results: Of the 800 dentists surveyed, a total of 221 questionnaires were completed and returned (response rate 27.6%). A vast majority of dentists (96.38%) identified tobacco as the major risk factor for oral cancer, and 82.8% knew that squamous cell carcinoma is the most common form. While 47.1% of the dentists agreed that they were adequately trained in oral cancer screening, the majority (86%) believed that they need further training in oral cancer screening. Conclusions: These results suggest that additional training and continuing educational programs on prevention and early detection of oral cancer for dentists are to be highly recommended.
