Analysis of histopathological diagnostic service in Department of Oral Pathology, Tokushima University School of Dentistry, 1979-1983

This study is based on an analysis of biopsy specimens that were diagnosed histopathologically in the Department of Oral Pathology, Tokushima University School of Dentistry from 1979 to 1983. This paper is presented with special reference to the oral mucosal lesions and other lesions except tumorous and cystic lesions in this series.1. The total number of cases related to oral mucosal lesions during these five years were 160, that is, 12.8% of all cases.2. The most common lesion of the oral mucosa was epithelial dysplasia (47 cases), followed by fibrous polyp (43 cases) and denture fibrosis (14 cases).3. The epithelial dysplasia was found in the older age group and most frequent site was the gingiva, followed by the tongue and buccal mucosa.4. The most common lesion except tumorous, cystic and mucosal lesions was radicular granuloma (43 cases) followed by epulis (38 cases).5. Radicular granuloma was found in anyage and the most common site was the gingiva of maxilla. Microscopically, cases of 30.2 per cent contained epithelium within the granuloma.6. The epulis was observed in anyage and more frequent in the maxilla. Microscopically, cases of 60.5 per cent were epulis granulomatosa and fibrosa.
