The aim of this study was to investigate the frequency distribution of oral biopsies from ۲۰۰۹ to ۲۰۱۹.Methods: In this analytical descriptive cross-sectional study, ۶۲۱ records of the oral cavity biopsies performed in the pathology department of Shahid Sadoughi hospital were analyzed. Age, gender, type of lesion, site of lesion, histopathological diagnosis, year of referral, and medical specialist who performed the biopsy were included in the study checklist. The data were analyzed using chi-square and Kruskal-Wallis test in SPSS version ۲۵.۰.Results: Of ۶۲۱ biopsies, ۳۰۸ specimens belonged to men (۴۹.۶%) and ۳۱۳ specimens belonged to women (۵۰.۴%). The mean age of patients was ۴۶.۵۸±۲۱.۰۸ years, ranging from ۶ months to ۹۵ years. The most affected areas were the tongue (۳۳%), lower lip (۲۹.۱%) and cheeks (۱۷.۷%). squamous cell carcinoma (SCC) (۲۷.۹%), inflammatory lesions (۲۶.۱%), mucocele (۱۴.۸%), and ulcers (۸.۵%) were the most frequent lesions. There was a significant difference in the age of individuals with different lesions (P<۰.۰۰۱).Conclusion: The most frequent lesion diagnosed in biopsies was SCC.
