[Dilantin gingival hyperplasia: patient evaluation in relation to anticonvulsant dosage, degree of oral hygiene and extension of lesion].

The authors examined 42 exceptional children interned in an especialized school viewing to determine the degree of gingival hyperplasia and it relation to the degree of oral hygiene, the lesion extension and the drug taken. All children were examined without verifying if they were taking any type of medicine. In the comparison of clinical exames of children taking anticonvulsants, the conclusion was that the gingival hyperplasia was present in 46.8% of the cases, as well as the extension of it being larger when the drug had been administrated for a long period and/or when oral hygiene was inadequate.
