Enamel carious lesions are characterized by demineralization, resulting in greater visual enamel opacity due to alteration of the refractive index of the affected area. This may cause esthetic concerns among most patients and if left untreated may lead to further progression of the lesion. Several treatment options like bleaching, microabrasion, and resin infiltration, composite resin bonding are available to attain the natural tooth colour. Resin infiltration technique is gaining importance with passing years. It is not only used to manage hypomineralized incisors but also provides esthetic rehabilitation and is minimally invasive. This case report describes 2 cases of molar incisor hypominaralization and its treatment using Resin Infiltration technique.
