Estudo epidemiológico de lesões orais em laboratórios de anátomo patologia na cidade de Fortaleza-Ce

Abstract

A wide range of diseases can affect the oral cavity, from developmental defects to metastasizing malignant neoplasms. The knowledge on Oral Pathologies`s prevalence helps the clinician making differential diagnosis. The aim of this study was to perform an epidemiological survey of oral lesions in five anatomopathological laboratories in Fortaleza, Ceará, Brazil. Methods: The sample was obtained from histopathology reports of oral lesions diagnosed between the years of 2001 to 2005 in five anatomopathological laboratories. Data regarding sex, race, age, anatomical site and histopathological diagnosis were registered. Lesions were categorized in non-neoplastic, neoplastic and descritive reports. Results: During the five-year period, 6231 oral lesions reports were collected, 41,41% from private laboratories and 58,59% from public laboratories. Female were more affected, with a male:female ratio of 1:1,68. Lesions occurred in a wide age range, varying from 0 to 100 years old, with an incidence peak between 31 to 60 years. Non-neoplastic lesions represented 64,89% of cases, with inflammatory/reactive lesions being the most prevalent group, followed by inflammatory lesions of salivary glands, cysts and non-atypical epithelial hyperplasia. Neoplastic lesion represented 30,80% of cases, 59,52% benign, 32,45% malignant and 8,03% pre-malignant lesions. Fibroepithelial hyperplasia was the most common lesion in this study and squamous cell carcinoma was the most prevalent malignant neoplasm, with 23,14% and 8,52%, respectively. Conclusions: Oral lesions were more common among female’s reports, in economically active age, mainly represented by inflammatory/reactive lesion. Although, the occurrence of inflammatory/reactive lesions was high, the prevalence of malignant neoplastic and pre-malignant lesion was significant. There dental surgeon must know about the occurrence of such lesions, and public health politics for prevention and early diagnose must be enfasized.
