Oral Cancer Awareness Among Princess Nourah bint Abdulrahman University Dental Students and Interns

Background: Dentists have a very important role in the early diagnosis of oral cancer premalignancy. This aspect of dental practice requires an adequate level of knowledge. Objective: This study aimed to assess the level of knowledge of undergraduate dental students and dental interns about early diagnosis and risk factors of oral cancer. Methods: The present cross-sectional study was conducted at the Dental College, Princess Nourah bint Abdulrahman University, Saudi Arabia. Fourth-year and fifth-year students and dental interns were enrolled in the study. The participants were recruited using a convenient, non-probability sampling method. A total of 103 participants filled out a close-ended, online questionnaire. We used descriptive and analytical statistics to analyze the responses to the questionnaire. Results: The level of general knowledge was moderate (67%). More than half of the participants gave complete responses to questions related to early signs of oral cancer (67%), risk factors (54%), risk sites (75%), treatment plans for leukoplakia (66%), and unhealed ulcer management (58%). We found significant associations between the correct responses and the year of the study regarding early signs of oral cancer (p=0.0001), high malignant potential lesions (p=0.00001), and chronic unhealed ulcer management (p=0.015). Conclusion: A more satisfactory level of awareness is needed among future dentists, to prevent missing patients undiagnosed with early oral cancerous lesions during routine screening. Consequently, upgrading theoretical curricula, clinical experience, and post-graduate participation in cancer prevention programs is highly recommended.
