REACTIVE LESIONS OF THE ORAL CAVITY: A RETROSPECTIVE STUDY ON 147 CASES

Objectives: the stratified squamous epithelium of the oral mucosa protects the oral cavity against pathogenic factors. if the local and systemic factors affect the epithelium, reactive, inflammatory, developmental, and neoplastic lesions may occur. the aim of this study is to determine the frequency and distribution of oral cavity reactive lesions at hatay and gaziantep. material and method: in this retrospective study, histopathologic diagnoses of reactive lesions of oral cavity in 147 patients were investigated. the patients referred to mustafa kemal university, faculty of dentistry, hatay and gaziantep university, faculty of dentistry, gaziantep between january 2009 and august 2013. the obtained frequency of patients’ age, gender and anatomic location were analysed. result: peripheral giant cell granuloma was the most common lesion with 56 cases (38,9%) followed by pyogenic granuloma with 39 cases (26,53%), epulis fissuratum with 26 cases (17,68%), irritation fibroma with 10 cases (6,8 %), inflammatory fibrous hyperplasia with 8 cases (5,44%), cemento-ossifying fibroma with 7 cases (4,76%) and inflammatory papillary hyperplasia with 1 case (0,68%). the lesions were more common in females (n=83, 56,46%) than in males (n=64, 43,54 %). the gingiva with 115 cases (78,23%) was the most frequently affected place of reactive lesions. conclusion: reactive lesions of oral cavity are more common in females than in males. the gingiva is the most frequent place. in our study, peripheral giant cell granuloma was the most common lesion.
