Abstract
Nineteen severely retarded children were studied to evaluate distribution, severity and control of phenytoin-induced gingival overgrowth (PIGO). Observations included the Plaque Index, the Gingival Index and the PIGO Index. Eighteen of these patients had gingival overgrowth with 47% having the severest type of involvement and all having severe overgrowth in the posterior regions. Elimination of topical, oral contact of phenytoin did not appear to alter gingival overgrowth. Use of SnF2 as an antiplaque agent significantly decreased plaque and overgrowth scores. Use of an electric toothbrush quite significantly decreased gingival inflammation, plaque scores and gingival overgrowth.
