Combined effects of a fluoride dentifrice and mouthrinse on the incidence of dental caries

Abstract
Children (751) 14- and 15-yr-old completed a 3-yr, double-blind, caries preventive program. The effects of daily, supervised toothbrushing with an 0.76% sodium monofluorophosphate dentifrice, rinsing with a 0.05% sodium fluoride mouthrinse and the combined effects of the 2 treatments were investigated. Both the dentifrice and mouthrinse reduced the incidence of dental caries, but their combined use at the same time had no greater effect than either used alone.
