Objectives:

Describe the effectiveness of the use of different desensitizing agents contained in dentifrices and mouthwashes for the control of dentin hypersensitivity in adults.

Method:

An electronic search of the scientific evidence available was made in PubMed, Epistemónikos, EBSCO, BEIC and Cochrane Library; using a search strategy that included the key words. For each article found the level and quality of evidence, risk of bias and ethics were analyzed.

Results:

A total of 36 articles were included, 29 randomized controlled clinical trials and 7 systematic reviews. Of the clinical trials, five tested the efficacy of mouthwashes, two made a comparison using dentifrices and mouthwashes and 22 tested only the use of dentifrices. The desensitizing agents mainly found were potassium salts, arginine, nano-hydroxiapatite, calcium sodium phosphosilicate (CSPS) and strontium salts. Only the first two were tested in both presentations. All the clinical trials demonstrated a reduction in dentin hypersensitivity with the use of an agent in comparison to the initial measurement.

Conclusions:

The use of nitrate and citrate potassium, arginine, calcium sodium phosphosilicate and nano-hydroxyapatite in dentifrices for the treatment of hypersensitivity may be recommended.
