Title Potassium Nitrate Sodium Fluoride Toothpaste Reduces Tooth Bleaching Sensitivity
Clinical Question For patients receiving tooth whitening, will the use of potassium nitrate sodium fluoride reduce dentin sensitivity as compared to no treatment.
Clinical Bottom Line Potassium nitrate sodium fluoride may be more effective in reducing bleaching sensitivity as compared to no treatment, however, more research needs to be completed.

Key resultsTooth sensitivity associated with tooth bleaching was significantly reduced with the use of a potassium nitrate sodium fluoride toothpaste.
#2) 19797554Tay/2009Patients with bleaching sensitivity Clinical Control Trial
Key resultsTooth sensitivity associated with tooth bleaching was significantly reduced with a desensitizing gel containing potassium nitrate sodium fluoride.

Comments on
The Evidence
Both the Reis and Tay articles reported clinical control trials involving patients comparing the use of potassium nitrate sodium fluoride to reduce tooth bleaching associated tooth sensitivity as compared to no treatment. No meta-analysis was done.
Applicability Neither the Reis or Tay articles reported patient selection criteria for the individual trial. Therefore, it is not sure whether the patients in this trial are representative of the general population. The use of potassium nitrate sodium fluoride would be feasible and patients could experience relief from bleaching sensitivity at a minimal cost.
