PP019: Evaluating the capacity of Syrian dentists in diagnosis of oral cancer and precancer lesions

Abstract

Purpose Early diagnosis is a crucial step for reducing cancer morbidity and mortality. Initial detection of precancerous lesions essentially relies on the vigilance of dentists working in primary healthcare. The aim of this questionnaire-based study was to evaluate the ability of dentists practicing in Damascus to correctly diagnose potentially malignant lesions. This information serves as a base line to ascertain educational needs of dentists in the Damascus area. Subjects and methods 93 dentists completed a study questionnaire comprising 9 questions assessing experience and knowledge of diagnostic techniques for oral cancer and precancer and 21 clinical cases including 7 oral cancers, 7 oral precancers, and 7 benign lesions. Dentists were asked to determine the type of each lesion, the need for biopsy, and a management plan for each case. Results No correlation was found between correct diagnosis of lesions and number of years clinicians had been registered dentists. In total, 37% of participants had performed at least one incisional biopsy during their professional life, 69% of them were unable to carry out a brush biopsy or to apply toluidine blue (84%). 95% respondents had never attended any course concerning oral diagnostic methods, but 77% of dentists had referred patients with potentially malignant oral mucosal lesions. Only 5% respondents correctly identified all clinical cases. Surprisingly, 9% of respondents failed to identify benign lesions correctly, 18% of precancer lesions, and 29% of cancer lesions. Conclusions This study emphasizes a need for improving the clinical diagnostic ability of dentists practicing in Damascus in order that patients who might benefit from early precancer intervention are not missed. We believe that reviewing the undergraduate oral medicine curriculum providing oral medicine education opportunities at a postgraduate level will improve the current situation.
