A FIVE-YEAR RETROSPECTIVE STUDY OF PROVISIONAL AND FINAL DIAGNOSIS IN BIOPSIED JAW LESIONS Elif Peker, Faruk O gutlu, Merve Cakir, Ozkan Buyuk, Elif Sibel Gultekin, Inci Rana Karaca, Department of Oral and Maxillofacial Surgery, Gazi University, Ankara, Turkey; Department of Oral Pathology, Gazi University, Ankara, Turkey Objective: The definitive diagnosis of jaw lesions is essential. However, their clinical and radiological appearance may mimic each other. The aim of the present study was to determine the accuracy of provisional diagnosis and to emphasize the importance of performing biopsy. Study Design: A retrospective analysis of 1473 lesions was made. Results: The study revealed that concordance between provisional and histopathological diagnoses of all lesions was 80.5%. Periapical granuloma, which provisionally diagnosed as radicular cyst, constitutes the overwhelming majority of the diagnostic disagreements. This data did not surprise us because of the same pathogenic process they have. Keratocystic odontogenic tumor, which diagnosed as dentigerous or radicular/residual cyst provisionally, was the other most common diagnostic disagreement. The another most common type was ameloblastoma that diagnosed provisionally as dentigerous cyst. Conclusions: The study emphasizes the diagnosis of jaw lesions should be based on clinical, radiographic, and histopathologic features.
