A new desensitizing dentifrice--an 8-week clinical investigation.
An 8-week, double-blind, three-way clinical trial compared the dentinal hypersensitivity-reducing effectiveness of a new dentifrice containing 5.0% potassium nitrate and 0.454% stannous fluoride in a silica base (Colgate Sensitive Maximum Strength Toothpaste, Colgate-Palmolive Co.) with a commercially available desensitizing dentifrice containing 5.0% potassium nitrate and 0.243% sodium fluoride in a silica base (Sensodyne Fresh Mint Toothpaste, Block Drug Company, Inc.) and a nondesensitizing dentifrice containing 0.243% sodium fluoride in a silica base (Colgate Winterfresh Gel, Colgate-Palmolive Co.). One hundred nine subjects were stratified into three balanced groups according to gender, age, mean baseline tactile (Yeaple Probe), and thermal (air blast) scores. The test products were randomly assigned to each group with instructions to brush twice daily. Oral examinations with tactile and thermal assessments were repeated after 4 and 8 weeks. The new dentifrice group demonstrated statistically significant improvements in tactile and thermal sensitivity over the two control groups.
