Objective An epidemiological survey of oral soft tissue proliferative processes diagnosed at the center of Pathological Anatomy of Oral ASCES Faculty. Methods We analyzed all the histopathological reports in the period from 1999 to 2009 as regards the following variables:histopathologic diagnosis, sex, age, symptoms, type of biopsy and location of the lesion. Results Non-neoplastic proliferative processes were present in 328 of the 938 reports analyzed, reaching a prevalence of 35 %. The most common injury was fibrous hyperplasia (81.4%) followed by pyogenic granuloma (11%) and peripheral giant cell lesions (6.1%). Fibrous hyperplasia was more prevalent in females, in the age group 40 to 59 years, where the most frequently performed biopsy was the excisional type, with the most frequent location being the buccal mucosa, and in most cases, no painful symptoms were reported associated with it, demonstrating significant difference between the variables studied (p < 0.001). Conclusion Non neoplastic proliferative processes processes are found in the general population, more common in females, affecting wide age-range, predominantly in individuals in the fifth and sixth decades of life, and fibrous hyperplasia was the most frequently found lesion.
