About

Molar-incisor hypomineralization (MIH) is a qualitative enamel defect, in which molars and incisors involved are prone to post-eruptive enamel breakdown leading to sensitivity, and caries. Atraumatic/Alternative Restorative Treatment (ART) is a minimally invasive procedure. It can be very beneficial in managing MIH-affected molars in communities with limited access to dental care. Zirconia-reinforced GI was recently introduced. It is claimed to serve as a long-term temporary restoration until a more permanent restoration is placed
