Abstract

Dentists are usually the first group who can examine patients for oral cancer and the early diagnosis highly depends on their knowledge. In this study, we aim to survey the Iranian dentists’ knowledge, attitude, and behaviors regarding oral cancer. A valid and reliable self-administered questionnaire was designed and sent to 150 dentists. Responses to the questionnaires were analyzed using descriptive and analytical statistics. Just one fifth of the dentists reported to perform oral cancer examination for all of their patients in age of 40 and above and about 34 % of them were knowledgeable. They mostly claimed that the lack of knowledge is the main barriers to the provision of routine oral cancer examinations. The opinion of dentists about the effectiveness of continuing education courses supports the development of these courses on oral cancer. Besides, more emphasis should be placed on oral cancer prevention in dental schools.
