Abstract
The aims of this study was to report on 3 cases with gingival hyperplasia caused by diphenyl hydantoin, and to examine the dental treatment planning for these patients.
The c a ses were as follows:
Case 1: The conten t s of the treatment for gingival hyperplasia was gingivectomy on the full mouth. This treatment was decided upon due to the possibility of good plaque control by the patient himself and by his parents. However, after the operation, he suffered from alopecia areata because of stress induced by the plaque control of his parents. After that, plaque control by his parents was discontinued and gingival hyperplasia caused by diphenyl hydantoin recurred.
Case 2,3: These patients had a systematic problem (anemia) ca u sed by bleeding from the gingiva. Therefore, their chief complaint was the treatment of gingival inflammation. Extraction of the teeth associated with the gingival hyperplasia was performed as a form of treatment for eleviating the gingival inflammation according to our judgement from the bad plaque control behavior of patients. With this then, the gingival inflammation was eleviated, and the anemia was cured.
Therefore, the results based on the above all were as follows: The important factors for conducting the dental treatment concerning gingival hyperplasia caused by diphenyl hydantoin are good plaque control without stress and chief complaints. Also, if a patient or parents could conduct the good plaque control, the gingivectomy should not be performed.
