title: Diphenylhydantoinate-induced hyperplasia of the masticatory mucosa in an edentulous epileptic patient.
abstract: Gingival hyperplasia caused by phenytoin sodium is rarely encountered in edentulous persons. A case of generalized palatal hyperplasia is reported in which retained roots and teeth were suspected of having perpetuated a preextraction lesion, whereas a subsequently placed complete denture initiated a midpalatal hyperplasia. The lesion remained in spite of nonuse of the denture for several years.
