Abstract
We clinically studied 624 cases of oral mucosal lesions at our clinic from 1990 to 1992 to evaluate their clinical features and treatment methods.
1) The most common diagnosis was aphthous lesion and stomatitis (44.2%), followed by glossitis, lichen planus, malformation of the tongue, infectious disease, leukoplakia, and cheilitis or angular cheilitis.
2) The ratio of males to females was 1: 2.0. Oral mucosal lesions occurred predominantly in patients who were 40 to 69 years of age.
3) The most common location was the tongue (47.0%), followed by the buccal mucosa (15.5%), lip, gum, palate, and floor of the mouth.
4) Pain was the most frequent chief complaint.
5) The majority of cases were treated successfully by medication alone, except for 2 cases of lichen planus and 20 cases of leukoplakia who required surgical treatment.
