    Abstract:
    Oral submucous fibrosis (OSMF) is a well-known precancerous condition. Epithelial atrophy is one of the key features in OSMF. Presence of Candida in the mouth together with epithelial changes may predispose to candidal infection. Candidal infection together with other co-factors may also induce epithelial atypia and dysplasia leading to malignant change. The purpose of this study was to determine the prevalence of oral yeast carriage in patients with OSMF and to compare the carriage with the normal individuals. Thirty patients with histologically proven OSMF and healthy subjects were used as the test and control respectively. Oral rinse samples were collected from all the subjects and cultured on Sabouraud's agar. Species were identified using API 32C AUX identification kits. Nineteen (63.6%) of the test group and 15 (50%) of the control group had yeast isolated from their mouth. The carriage of yeast in the OSMF group was not statistically significant compared with the control group. We isolated C. dubliniensis in Sri Lanka for the first time and interestingly from the oral cavities of both OSMF patients and healthy individuals.
