ABSTRACT
Molar incisor hypomineralization (MIH) is the most common developmental enamel defect and most involved in permanent first and second molars. In MIH-affected molar teeth, a 6-step treatment management plan includes risk identification, early diagnosis, remineralization, prevention of caries and material loss, restoration after removal of caries and defects or extraction, and maintenance. The severity of the defect, the age and cooperation of the child, the presence of symptoms, the expectations of the patients, the reaction of the patients to repeated treatments, aesthetic requirements, oral hygiene habits, and the cost-effectiveness of the treatments are the factors that should be taken into consideration in the treatment plan and restoration management. Management of MIH-affected molars is complicated for both the practitioners and the patients. The low mineral and high protein content of defective enamel prevents the effective bonding of adhesive systems. The micro-shear and micro-tensile bond strength values of resin composite bonding to hypomineralized enamel are significantly lower than those of sound enamel. Although various materials have been investigated, glass ionomer cement, fissure sealant, composite, stainless-steel crown, and indirect restorations can be used case-specific in clinical practice.
