Material and Method: In this retrospective study, the histopathological reports of patients who underwent biopsy between February 2013 and May 2018 were examined and analyzed. Gender, age, location of the lesion, clinical and final histopathological diagnoses were determined from patient records. The lesions were divided into three main categories according to their final histopathological diagnosis: Group 1 (Developmental, inflammatory, reactive lesions of the jaws), Group 2 (Cystic lesions), and Group 3 (Tumors and tumor-like lesions). Results: The records of 506 patients were examined in the study. Patients’ ages ranged from 8 to 80 years (mean: 37.1 ± 17.5). The distribution of lesions by groups was as follows: Group 1: 105 (20.8%), Group 2: 333 (65.8%), and Group 3: 68 (13.4%).Two hundred and seventy-five of the patients were male (54.3%) and 231 of them were female (45.7%). Two hundred and fifteen of the lesions were localized in the maxilla (42.5%) and 291 of them were localized in the mandible (57.5%). The concordance rate of diagnoses was 87.4% as a result of the comparison of clinical and final histopathological diagnoses. Discussion: The clinician’s knowledge about the lesion has a significant effect on the concordance between clinical and histopathological diagnoses. The correct and early diagnosis of lesions will prevent unnecessary treatments and delayed surgical operations.
