In molars with MIH and the need for restorative treatment, stainless steel crowns had a significantly higher survival rate than composites over 24 months.

Currently, there is no consensus on the superiority of any material for the restorative treatment of molars affected by molar-incisor hypomineralisation (MIH). This retrospective cohort study evaluated the survival of restorations with stainless steel crown (SSC) or composite resin (CR) in first permanent molars affected by MIH for 24 months. Sixty-one CR and 54 SSC restorations performed on molars affected by MIH of patients, aged between seven and ten, that were treated and overseen at a university dental clinic in the period of 2017-2020 were evaluated. The primary outcome was the failure-free survival time. The survival of SSC and CR restorations after 24 months was 94% and 49%, respectively. This difference was influenced by the presence of previous restoration and cusp involvement. In molars with MIH and the need for restorative treatment, SSC had a significantly higher survival rate than CR over 24 months.
