After 4 wks, subjects assigned to the Colgate Sensitive Maximum Strength dentifrice group exhibited a statistically significant improvement over the Sensodyne dentifrice group with respect to tactile sensitivity scores, and a statistically significant improvement over the Sensodyne dentifrice group with respect to air blast sensitivity scores. Correspondingly significant improvements were presented after 8 wks. Thus, the results of this examiner-blind clinical study support the conclusion that the Colgate Sensitive Maximum Strength dentifrice containing 5.0% potassium nitrate and 0.454% stannous fluoride in a silica base provided superior levels of control of tactile and air blast sensitivity than the clinically tested, commercially-available anti-hypersensitivity dentifrice Sensodyne dentifrice containing 5.0% potassium nitrate and 0.76% sodium monofluorophosphate in a dicalcium phosphate base.
