Tratamento restaurador de molares gravemente afetados por Hipomineralização Molar Incisivo: uma revisão da literatura

Abstract

The objective of this review was to report on the materials used and their clinical application in the restorative treatment of hypomineralized molars with post-eruptive enamel fractures involving two or more surfaces and extending to the cusps. To compose the review, selected clinical studies on the subject, conducted in humans, in the form of original research and case reports, were included. A total of 631 articles were retrieved from the MEDLINE (PubMed), SciELO, and Virtual Health Library (VHL) databases. Inclusion criteria were studies published in full text, in Portuguese, English, or Spanish, addressing the restorative treatment of molar incisor hypomineralization. Exclusion criteria included duplicate articles, in vitro studies, literature reviews, publications that did not present relevant clinical outcomes, and those without access to the full text. Initially, 631 articles were identified. After applying the eligibility criteria, we obtained 7 articles for the review, conducted in countries such as Mexico, Colombia, Brazil, India, Turkey, and Greece, in patients aged between 6 and 15 years. The restorative materials found were glass ionomer cement, composite resin, cast metal onlays and indirect composite resin onlays, prefabricated zirconia and stainless steel crowns, and cast metal and lithium disilicate (e-Max) crowns. The analysis of clinical performance demonstrated that direct approaches, such as glass ionomer cement and composite resin, presented limited results, while indirect approaches, such as cast metal onlays and indirect composite resin onlays, prefabricated zirconia and stainless steel crowns, and cast metal and lithium disilicate crowns, have greater predictability and durability in these composite cases.
