Evaluation of clinical versus pathological difference in 232 cases with oral lesion

Background: The clinical and pathological evaluation of oral lesions are very important in this field. The purpose of this study was to assess clinico-pathological agreement on 232 cases with oral lesion s. Methods: The consecutive files of 232 patients with oral lesions from pathological laboratory archives of Babol Dental faculty and Shahid Beheshti Hospital were reviewed and the data include age, sex and location of lesion, surgeon's specialization, clinical and histopathological diagnosis were recorded. Frequency of oral lesions and rate of correct clinical diagnoses were evaluated in site of lesions and surgeon's specialization. Results: Non neoplastic lesions were more common than neoplastic lesions. Soft tissue reactive lesions were the most common oral lesions. The Correct clinical diagnosis in soft tissue and intra-osseous oral lesions was 66.2% and 66.6% respectively. Clinico-pathological agreement cases were seen in oral and maxillofacial surgeons (68.5%), oral medicine specialists (64.27%) and periodontists (61.9%). From 165 selected oral lesions, the histopathological and clinical diagnoses were in agreement in 110 cases (66.6%). The highest percentage of correct clinical diagnosis was found in mucocele (92.3%) (KS= 0.916, SE-0.59) and the lowest was lymphoproliferative lesions 27.3% (KS-0.378, SE-0.16). While in all other groups 36-86% of cases were in agreement. Conclusion: The results of this study show that there is a good agreement between the clinical and pathological diagnosis of oral lesions. The most clinico- pathological agreement was seen in mucocele and the lowest was lymphoproliferative disorders.
