Abstract

Introduction: Molar-incisor hypomineralization (MIH) is a qualitative defect of the enamel structure affecting at least one of the first permanent molars. Treatment will depend on its severity, the stage of dental development and the cooperation of the young patient. The aim of this study is to compare the different materials used for direct restorations on teeth with MIH. Methods: A systematic review was conducted on May 2024 and is described according to the PRISMA criteria. It was performed on three databases PubMed, Science Direct, and Google Scholar). Twenty-nine articles were included. Results: 14 studies (48.3%) described the use of glass-ionomer cement (GIC), among which 12 concluded that its use could be recommended as a temporary material in the presence of MIH, protecting the tooth while awaiting a definitive restoration. Composite resins were described in 21 studies (72.4%), in association with both etch-and-rinse and selfetch adhesive systems. Conclusions: For direct tooth restoration in case of MIH, GIC seem to meet the objective of preserving the child’s quality of life by protecting teeth during their eruption with an acceptable survival rate. The use of dental composite resins is more restrictive and will be optimal with complete removal of hypomineralized tissue.
