Objectives:

To identify the evidence of primary dentin hypersensitivity (DH) management using different treatments such as topical agents, surgery, or laser.

Materials and methods:

A systematic search was performed with the MeSH terms related to the research topic using a single comprehensive literature search algorithm in the computerized databases of MEDLINE, Cochrane Register of Controlled Clinical Trials, OVID, and Scopus. We only included randomized controlled clinical trials that included patients with HD associated with sensitive dentin with open tubules in the permanent dentition and who underwent HD treatments with laser therapy, surgical treatments, or topical therapy, evaluating the level of pain with the Visual Analogue Scale (VAS).

Results:

34 articles were selected. It was found that among treatment alternatives to reduce primary HD, topical agents and the use of laser are interventions that significantly improve the pain response, however, better results were obtained when using both techniques in combination.

Conclusions:

The results of this study allow us to conclude that there is evidence of the efficacy of managing primary HD through interventions with laser therapy and topical agents. This work opens a new path towards future research that evaluates the long-term effects of this type of intervention and its adverse effects.
