Eficácia de procedimentos não restauradores para manejo da hipersensibilidade em dentes afetados por Hipomineralização Molar Incisivo: revisão sistemática

Abstract

The clinical management of MIH (Molar Incisor Hypomineralization) is challenging and depends on the degree of involvement. Strategies range from prevention of dental caries with remineralizing products to restorative treatments to control sensitivity and restore dental function and aesthetics. However, the efficacy of non-restorative strategies for the management of hypersensitivity still lacks consensus in the literature, which limits the definition of clinical protocols. This systematic review investigated the efficacy of non-restorative treatments for the management of hypersensitivity in teeth affected by MIH. Searches were performed in five databases by two independent reviewers and there were no restrictions regarding language or date of publication. The risk of bias was assessed using the Cochrane collaboration tools Rob2 and Robins, for randomized clinical trials and interventional clinical studies, respectively. A total of 567 articles were identified and after removing duplicates, screening by titles and abstracts, and subsequently reading the full texts, seven studies were included in this review. The noninvasive treatments investigated were the use of desensitizing pastes, sealants, laser, ozone, and their combinations with comparisons between them. Most studies presented a high risk of methodological bias. The results suggest that the different noninvasive procedures present satisfactory results for reducing sensitivity in patients with MIH, with emphasis on desensitizing pastes and laser treatments. However, more studies with robust methodological designs are needed to confirm the effectiveness of these approaches and establish clear guidelines for clinical practice.
