RESUMO

Epidemiological studies of oral diseases are important to verify the relative prevalence of reactive, infectious, cystic and neoplastic lesions, and to determine strategies of prevention and treatment. Moreover, geographical differences may lead to clues regarding the causes of these lesions. Frequency of oral diseases varies throughout the world, and it is important to have information not only of countries, but also of each specific region. For example, Brazil has enormous differences among its regions relating to economical, cultural and demographic aspects that may reflect different prevalence of oral lesions. So, the purpose of this study, presented as two distinct publications, is to: 1. - show the frequency of 8,875 oral and perioral lesions submitted to the Oral Diagnostic Service of the Oral Pathology Department at the School of Dentistry of Piracicaba - UNICAMP, Brazil during a 32-year period; 2 - to verify particularly the Odontogenic Tumors frequency at the same period of time; 3- a computer database software was developed to collect and store the data. The assessment method consisted of reviewing ali microscopic slides and available clinical data by two examiners; data storage on the developed software and finally, the epidemiological analysis. As a result of the first work, it could be seen that the majority of the oral biopsies were taken from either infectious or reactive lesions as fibrous hyperplasias (26%), periapicallesions (11 %) and periodontitis (10%). Squamous cell carcinoma was responsible for 5% of the total cases and corresponded to 86% of ali malignant neoplasms. It is interesting to notice the occurrence of 150 cases of paracoccidioidomycosis. Odontogenic tumours corresponded to 1.26% of the total. As for the results of the second article, it is noticed that among the 113 Odontogenic Tumors cases, 39.4% were odontomas, 22.1 % ameloblastomas and only one malignant case, diagnosed as malignant Ameloblastoma. In addition, the cases occurred predominantly in the second and third decades of life, and the posterior region of the mandible was the most affected site to ameloblastomas whereas anterior maxilla was to odontomas
