Rehabilitation Treatment in Pediatric Patients with Molar Incisor Hypomineralization: A Scoping Review

ABSTRACT Objective: To identify the available evidence on the different treatment types for the rehabilitation of MIH-affected teeth in children. Material and Methods: A search was carried out in Pubmed, Cochrane Library, Epistemonikos, Lilacs and Google Scholar. Observational studies published until June 2022 were included. Two reviewers independently screened studies and extracted data. Results: 1593 studies were screened and a total of 38 articles were included, which were mainly case reports published in Brazil. Most included studies concluded that the evaluated treatment was "beneficial" or "probably beneficial". Reported treatments included: glass ionomer cements (GIC), composite resin restorations, preformed metal crowns, laboratory fabricated crowns, microabrasion management of incisors and resin infiltration. Conclusion: Successful treatment options have been identified, such as GIC as a provisional restoration for severe cases and for uncooperative children; restorations with composite, indirect restorations, or preformed metal crowns also seem suitable treatment options for young patients diagnosed with MIH. There is still little evidence to support an approach for anterior teeth affected by MIH.
