Phenytoin-induced gingival overgrowth resulting in delayed eruption of the primary dentition. A case report.
A case of delayed eruption of the primary dentition secondary to phenytoin therapy in a 4-year-old child is reported. The patient had been on phenytoin therapy since the first months of life. Radiographs revealed that alveolar but not gingival emergence had occurred. Surgical excision of the excess gingival tissue was accomplished under general anesthesia. Oral hygiene procedures were stressed and parental cooperation solicited. Three- and nine-month postoperative visits revealed no regrowth of gingival tissue and continued eruption of the primary dentition.
