Histological Study on Gingival Hyperplasia by Aleviatin (Sodium Diphenylhydantoinate)

Sixteen cases, 5 males and 11 females, of hyperplastic gums resulting from aleviatin administration were histologically studied, and the pathogenesis of the gingival hyperplasia was discussed. The histological examination revealed much identity to the previous observations. However, the authors could not derermine whether in the beginning state of the gingival enlargement the inflammatory cell infiltration occurred or not.
