Background: Potassium nitrate has been used previously in a dentifrice or gel to alleviate dentinal hypersensitivity. The aim of this study was to compare a 3% potassium nitrate/0.2% sodium fluoride mouthwash with a 0.2% sodium fluoride control mouthwash in a 6‐week double‐blind study. Methods: Fifty subjects were evaluated using 2 tactile methods and cold air sensitivity (dental air syringe), along with subjective perception of pain (0 to 10 scale) at baseline and at 2 and 6 weeks. Results: There was a general decrease in dentinal hypersensitivity levels in both groups over the 6‐week study period as demonstrated by all 4 methods of assessment. There was also a statistically significant difference in decrease in sensitivity between the groups. Conclusions: This study showed that a 3% potassium nitrate/0.2% sodium fluoride mouthwash appears to have therapeutic potential to alleviate dentinal hypersensitivity. J Periodontol 2001;72:1720‐1725.
