The relative clinical effectiveness of three anticalculus dentifrices

A three-month double-blind clinical study was conducted to compare the effect of three commercially available antitartar dentifrices in retarding the rate of supragingival calculus formation. After a thorough dental prophylaxis, the subjects were instructed to brush their teeth twice daily with either Prevent, Crest Tartar Control Formula (TCF), or Colgate TCF. Supragingival calculus accumulation on the mandibular anterior teeth was measured after 3 months use of the assigned dentifrice. The results of this study showed that Prevent retarded calculus formation 38.0% more than Crest TCF. Colgate TCF retarded calculus accumulation by 36.0% more than Crest TCF. No significant differences in anticalculus effectiveness were noted between Prevent and Colgate TCF.
