Clinical comparison of the anticalculus efficacy of three commercially available dentifrices.

A three-month, double-blind, parallel and unsupervised clinical study was conducted to compare the effects on supragingival calculus formation of the following four dentifrices: 1) A placebo dentifrice containing 0.243% sodium fluoride in a silica base. 2) A commercially available anticalculus dentifrice containing 5.0% soluble pyrophosphate in a 0.243% sodium fluoride silica base. 3) A commercially available anticalculus dentifrice containing 1.3% soluble pyrophosphate and 1.5% of a Gantrez copolymer in a 0.243% sodium fluoride silica base. 4) A commercially available anticalculus dentifrice containing 3.3% soluble pyrophosphate and 1.0% of a Gantrez copolymer in a 0.243% sodium fluoride silica base. The three-month results indicated that the three commercially available anticalculus dentifrices provided statistically significant reductions (at the 99% level of confidence) in supragingival calculus formation of 43.87%, 46.60%, and 51.32% respectively, as compared to the placebo dentifrice. There was no statistically significant difference among the three commercially available anticalculus dentifrices.

Long-term evaluation of a prebrushing dental rinse for the control of dental plaque and gingivitis.

One hundred and three adults completed a double-blind, 6-month controlled study to assess the effects of rinsing with Plax (Oral Care Division of Pfizer Inc., New York, NY) before brushing on plaque, gingivitis and calculus. All the parameters were evaluated at baseline and after three and six months of home use of either Plax or placebo rinse. Microbiological components of plaque were monitored. Following prolonged use as a prebrushing rinse, Plax was no more effective than placebo in reducing plaque, gingivitis and calculus.
