Introduction: The reactive lesions are relatively common in the oral cavity. They often result from a known stimulus or injury such as dental plaque, calculus, or foreign material. Aims: The aim of this study was to review the clinicopathologic features of reactive hyperplastic lesions (RHLs) of the oral cavity at MIDSR, Dental College and Hospital, Latur, Maharashtra, India.

Settings and Design:This study is a retrospective archival review of reactive gingival lesions of oral cavity such as irritational fibroma (IF), inflammatory gingival hyperplasia (IGF), pyogenic granuloma (PG), peripheral giant cell granuloma (PGCG) and peripheral ossifying fibroma involving gingival tissues from the Department of Oral and Maxillofacial Pathology from June 2010 to May 2016 were were reviewed and analyzed for age, gender, and site of location.

Statistical Analysis Used: Descriptive statistics was applied to the data and differences in frequencies among groups were evaluated using SPSS (IBM Corporation) software.

Results:A total of 155 histologically diagnosed cases of RHLs were obtained with a prevalence of 11.7%. The data consist of 56 (36.1%) males and 99 (63.9%) females. The most common lesion clinically was traumatic fibroma (36.5%) and histologically fibrous hyperplasia (37.4%). The reactive lesions clinically presented as either sessile (51%) or pedunculated (49%) lesions.

Conclusions:Despite their clinical similarities, the findings of this study reports that all reactive gingival lesions show some differences in age, type, location, duration and histopathological features. Nevertheless, the differing histological pictures are a range of a single lesion in diverse stages of maturation. The novelty in our study was the correlation between histopathology and clinical features which were not reported in literature till date.
