Introduction: Developmental anomalies of oral mucosa are not necessarily related to a specific disease, that  may be demonstrated in differential diagnosis of oral disease and premalignant lesions. Mucosal anomalies incidence may be varied in different individuals, which can be related to many genetic and environmental elements. Therefore, this study aimed to evaluate the developmental anomalies of oral mucosa in the patients referred to department of Oral Medicine of Hamadan Dentistry faculty in 2014.

Methods: In this cross-sectional study, the developmental anomalies of oral mucosa were studied in 800 patients, who referred to Hamadan School of Dentistry in Iran. All the 800 patients were clinically examined using dental mirrors on the dentistry unit in regard with diagnosis of mucosal anomalies. Demographic data and types of mucosal anomalies were recorded in a predesigned questionnaire. In order to analyze the study data, SPSS software (ver, 16) was applied via chi-square test at significance level of 0.05.

Results: Oral developmental lesions were observed in 700 patients (87.5%). The most common lesion was reported as fissured tongue (50.9%), followed by Fordyce granules (49.5%), Macroglossia (17%), torousplatinus (13.4%). A significant association was detected between fissured tongue, macroglosia ,fordice granule with gender and age, Varicosities and furred tongue with age and Torus palatines , Comissural lip pit and hairy tongue with gender .

Conclusion: The findings of the present study revealed high prevalence of oral mucosal anomalies. As a result, dentists and medical practitioners are demanded to attend to the oral mucosal anomalies.
