Introduction: Molar incisor hypomineralisation (MIH) is a developmental defect that predominantly targets the first permanent molars and incisors and consists of hypomineralisation of the enamel. A range of treatment options are available to improve aesthetics in this condition, including resin infiltration, bleaching techniques, restorations, microabrasion, and laser therapy.
Objectives: This systematic review and meta-analysis aimed to analyse the effects of treatments on changes in enamel colour in teeth with MIH lesions and determine whether resin infiltration is the most aesthetic treatment.
