title: A follow-up study of sixty-one oral dysplastic precancerous lesions in Indian villagers.
abstract: In a 7-year follow-up study of 107 cases of oral epithelial dysplastic precancerous lesions in Indian villagers, 6.6 per cent were found to develop into carcinomas. A clinical spontaneous regression occurred in 14.8 per cent. Follow-up biopsies showed histologic regression of dysplasia in six cases.
