Treatment outcome for dentin hypersensitivity with laser therapy: Systematic review and meta-analysis

Abstract

Background. Laser protocols for the treatment of dentin hypersensitivity (DH) have not yet been studied systematically.Objectives. The present study aimed to review clinical trials on the treatment of DH with laser therapy through a systematic review and meta-analysis. Material and methods.The search of electronic databases resulted in 562 publications up to April 2020. The inclusion criteria were studies carried out on humans and reporting on the treatment of DH with laser therapy. Case reports, literature reviews and systematic reviews were excluded. Selected by abstract, potentially eligible papers were read in full (n = 160). Independent examiners performed data extraction and the assessment of the risk of bias.Results. A total of 34 studies were included in the analysis, and 11 in the quantitative analysis. It was observed that most studies followed up patients for a maximum of 6 months (55%). Through the meta-analysis, we observed statistically significant differences between the average pain before and after 3 months of treatment with high-and low-power lasers. However, through indirect comparisons, it was observed that the high-power laser showed a greater tendency to reduce the pain levels after 3 months of treatment as compared to the low-power laser, but without a statistically significant difference.Conclusions. It was possible to conclude that regardless of the type of laser used in the treatment of DH, this treatment is an effective option for the control of pain symptoms. However, it was not possible to establish a defined treatment protocol, since the evaluation methods are very different from each other.Text for Rewiew and clinical cases.

Influence of Er:YAG and ND:YAG laser irradiation and fluoride application on surface roughness and dentin surface wear after erosive challenge - An in vitro study

“…This allows the formation of hydroxyapatite crystals larger than os crystals observed in the initial structure, obliterating the dentinal tubules and consequently reducing HD ( 23 ). This reduction in HD was concluded in a systematic review and meta-analysis and it was verified that it occurs even after 3 months of treatment ( 24 ). Thus, laser therapy is a choice in controlling the symptoms of painful sensitivity, although there is no defined treatment protocol.…”

Effects of Semiconductor Laser Irradiation on Differentiation of Human Dental Pulp Stem Cells in Co-Culture with Dentin

“…In daily dental practice, dentists often encounter cases of hypersensitivity. Hypersensitivity is generally treated by applying desensitizers or adhesive dental materials to the exposed dentin in the cervical region, and laser therapy has also been applied [ 29 , 30 ]. Tissue-penetrating semiconductor lasers and Er:YAG lasers absorbed by the tissue surface are mainly used for laser treatment of hypersensitivity [ 30 ].…”

The mechanism of each laser’s action on hypersensitivity differs, and the details of the mechanism remain unclear.…”

Intraoral Applications of Lasers in the Prosthetic Rehabilitation with Fixed Partial Dentures—A Narrative Review

“…Nevertheless, a single appropriate laser therapy protocol for dental hypersensitivity has not yet been established. Different types of lasers, wavelengths, potencies, and application times and modes have been used by researchers over the years [54,56]. One of the significant advantages of using lasers for the treatment of this complaint is related to their immediate effects [54,55].…”

Additively, they are also safe and well-tolerated by patients [54,55].…”
