Use of high- and low-intensity lasers in the treatment of dentin hypersensitivity: A literature review

J Clin Exp Dent. 2021 Apr 1;13(4):e412-e417. doi: 10.4317/jced.57783. eCollection 2021 Apr.

Abstract

Background: Dentin hypersensitivity (DH) is defined as an exaggerated sensitivity of vital dentin exposed to thermal, chemical and tactile stimuli. This study aimed to evaluate, through a literature review, the applicability of high- and low-intensity lasers in the treatment of DH for the past 10 years, as well as its therapeutic potential.

Material and methods: The electronic databases MEDLINE/PubMed and LILACS were searched using the descriptors ("Dentin Sensitivity" OR "Dentin Hypersensitivity") AND ("Low-Level Therapy" OR Laser), for articles published between 2010 and 2020. Only randomized clinical trials with full-text and full case resolution were included.

Results: We found 187 articles in total, among which 61 were pre-selected and 10 included in this literature review.

Conclusions: Considering the found results and their possible limitations, high- and low-intensity lasers, associated or not with other therapies, have demonstrated beneficial effects in the treatment of DH, being considered a promising, safe, easy, and effective field of research, reducing pain sensitivity and preserving pulp vitality. Key words:Dentin sensitivity, dentistry, laser.
