Abstract |
The effect on dentinal hypersensitivity from the use 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.) over an 8-week period was compared to a commercially available dentifrice containing 5.0% potassium nitrate and 0.243% sodium fluoride in a silica base (positive control [ Sensodyne Fresh Mint Toothpaste, Block Drug Company, Inc.]) and to a commercially available nondesensitizing dentifrice containing 0.243% sodium fluoride in a silica base (negative control [Colgate Winterfresh Gel, Colgate-Palmolive Co.]). A total of 120 participants were stratified into 3 balanced groups according to baseline mean air blast (thermal) and tactile (Yeaple Probe) sensitivity scores, gender, and age. Participants brushed their teeth twice daily (morning and evening) for 1 minute. Dentinal hypersensitivity examinations were conducted at baseline, 4 weeks, and 8 weeks by the same dental examiner. After 4- and 8-weeks' use of their assigned products, participants in the new dentifrice group demonstrated statistically significant improvements (p < 0.05) in tactile and air blast sensitivity, as compared to those using the positive and negative control dentifrices.
