Abstract

Non-neoplastic proliferative lesions (NNPL) are frequently diagnosed in oral mucosa and are characterized by tissue proliferation, primarily with an inflammatory origin and without a neoplastic aspect. The aim of this work was to present an epidemiological study of NNPL cases from the Surgery Pathology Files of the School of Dentistry at São José dos Campos (UNESP) over a period of forty years. A total of 1,364 NNPL cases were analyzed (18.63% of all 7,300 cases in the archive). In the NNPL cases, 76.76% were diagnosed as fibrous inflammatory hyperplasia, 9.68% as pyogenic granuloma, 8.58% as peripheral ossifying/cementifying fibroma and 4.99% as peripheral giant cell granuloma. Patient age, gender, race and the anatomical site of the lesion(s) were also investigated. Among the NNPL cases, the most prevalent anatomical site was the gingiva (30.94%), and most cases occurred in female patients (65.61%), caucasians (75.8%) and at the 5th decade of life (21.77%), which is in agreement with the literature database. Since there is a high prevalence of NNPL in this population, a better understanding of the features of these lesions by the dentist is necessary. With these data, he will be able to correctly diagnose and treat these diseases.
