TREATMENTS FOR DENTIN HYPERSENSITIVITY: A LITERATURE REVIEW

Abstract

This article sought to critically analyze the available treatments for HD, considering their efficacy, safety, cost-effectiveness, and durability of effects, through a narrative review of the scientific literature. Twenty-six articles published between 2015 and 2024 were selected from the PubMed, Scielo, and Google Scholar databases, including clinical trials, systematic reviews, and meta-analyses. The treatments were grouped into three main categories: desensitizing agents, laser therapies, and biomaterials. Desensitizing agents, such as sodium fluoride, potassium nitrate, arginine, and bioglass, have been shown to be effective in obstructing dentinal tubules and reducing pain. Laser therapy, especially with diode and Er:YAG lasers, has demonstrated rapid and long-lasting results through modulation of neural activity and stimulation of reparative dentin. Biomaterials, such as calcium phosphate, hydroxyapatite and glass ionomer cements, have shown benefits in dentin remineralization and long-lasting effects. The review identified that the choice of the most effective treatment depends on factors such as severity of the condition, patient compliance, individual characteristics and the clinical protocol adopted. Despite advances, there are still gaps in the literature regarding the standardization of methods and comparison between approaches. Despite therapeutic advances, there is no single solution, as the response to treatment varies according to individual particularities, requiring a personalized approach that considers factors such as daily habits and emotional state.
