Use of Laser as a Treatment for Hypersensitivity Due to MIH

Abstract

Introduction: A high prevalence of patients with Molar-Incisor Hypomineralization (MIH) often present dentin hypersensitivity, which negatively impacts their quality of life and poses a challenge for dental care. Various treatments have been described, including the use of desensitizers, remineralizing agents, and lasers. Objective: To describe the use of lasers as a treatment for hypersensitivity in patients with MIH. Literature Review: A literature review was conducted using the databases Pubmed, Scielo, Google Scholar, and Epistemonikos, covering the period from 2014 to 2024. The search terms used were "Dentin hypersensitivity," "Molar-Incisor Hypomineralization," "Laser," and "Treatment." Systematic reviews, clinical cases, and case/control studies were included. The review identified the use of laser Er:YAG, Nd:YA, Er,Cr:YSGG, diode and low-level laser therapy (LLLT). Conclusions and Recommendations: Lasers have been shown to reduce immediate pain, although the duration of this relief is short. They are more effective and produce longer-lasting results when are combined with other desensitizing agents. Therefore, lasers represent a promising treatment method, providing an analgesic effect in the majority of studies.
