Abstract

Background: The aim of this study was to evaluate the histopathological findings of oral lesions in patients referred to the pathology department of Kosar Hospital of Semnan city (Iran) in 2012-2018.

Materials and Methods: This population-based cross-sectional study was concocted on the histopathological findings of oral lesions 137 patients referred to the pathology department of Kosar Hospital of Semnan city (Iran) in 2012-2018. The sampling method was census. The data collection tool was a check including demographics and dentistry (type of dental lesion, location of the lesion, malignancy of lesions, origin of dental lesions, side of the lesion conflict, jaw involved, anterior-posterior position and type of biopsy). SPSS24 was used for data analysis and a signifi- cance level of less than 0.05 was considered.

Results: The most common type and the most common location of oral lesions were periapical cyst (16.7%) and periapical (28.3%); respectively. The most common sources of oral lesions were related to inflammation and connective tissue with 27.5 and 26.8%, respectively. Mandible (47.8%) was the most common involved jaw and 5.1% of reported lesions were malignant. In addition, the prevalence of periapical cyst (78.3 vs. 21.7%) and pyogenic granuloma (82.4 vs. 17.6%) were significantly higher in women than men (P-Value=0.035).The highest rates of periapical cyst (43.5%) and pyogenic granuloma (58.5%) were observed in the age group ≤30 and 31-40 years; respectively (P-Value=0.013).

Conclusion: This study suggests that the female patients and over 40 years should be more careful to check for periapical cyst. However, more detailed studies with higher sample sizes are recommended.
