The effects of two oral prophylaxis methods on the oral hygiene performance of children (N=l00) between the ages of 8 and 13 years were studied over a three month period. Subjects were randomly selected from a dental hygiene clinic patient population and assigned to one of two prophylaxis groups. Each child's oral hygiene was evaluated using the Patient Hygiene Performance Index prior to and at one month intervals following treatment. Multifactor analysis of variance revealed no significant difference between children's age and the type of prophylaxis received. A significant difference was observed between children ages 8 to 10.5 and 10.6 to 13 years for the first three appointments; no significant difference was observed between the two age groups at appointment four. The self-administered prophylaxis is as effective as the rubber-cup prophylaxis in improving children's oral hygiene performance. Given adequate time, children ages 8 to 10.5 are capable of manipulating preventive materials as skillfully as children ages 10.6 to 13 years.
