It Is Unclear Whether Desensitizing Toothpastes Containing Stannous Fluoride Cause a Greater Reduction in Hypersensitivity Compared to Toothpaste Containing Potassium Nitrate Following Bleaching Treatment |
Clinical Question |
In an otherwise healthy patient with tooth sensitivity, will application of a desensitizing agent containing stannous fluoride cause greater reduction in sensitivity after bleaching compared to a desensitizing agent containing potassium nitrate? |
Clinical Bottom Line |
In patients with dentin hypersensitivity who are undergoing bleaching treatment, it is unclear if desensitizing agents containing stannous fluoride are more effective in reducing hypersensitivity than those containing potassium nitrate. |

22051246 | West/2011 | 28 Healthy volunteers | in situ Randomized Controlled Trial | Key results | A toothpaste containing stannous fluoride with a relative dentin abrasivity (RDA) value of 120 is more abrasive than a toothpaste containing potassium nitrate with an RDA value of 70. This higher RDA value causes the stannous fluoride containing paste to contribute significantly more to dentin erosion than the potassium nitrate containing paste (p < 0.0001). | |

Applicability |
While there are no studies available that directly compare the efficacy of toothpastes containing stannous fluoride and those containing potassium nitrate based on their desensitizing characteristics in patients undergoing bleaching treatment, both are popular active ingredients in sensitivity toothpastes and could be considered for these patients. |
