Molar incisor hypomineralization (MIH) is a developmental and qualitative enamel defect caused by reduced mineralization and inorganic enamel components that lead to enamel discoloration and fractures of the affected teeth.1 This condition involves permanent first molars and incisors, and presents as demarcated lesions that range from creamy-white to yellow-brown opacities; it may also involve post-eruptive enamel breakdown and atypical restorations. The teeth might present with sensitivity. It occurs during the calcification stage of tooth formation, and is essentially a defect in enamel calcification. Unlike other enamel defects, hypomineralization starts at the enamel-dentinal junction and proceeds to the enamel’s surface. Mild lesions affect the inner enamel, while the entire enamel is affected in severe MIH. The affected enamel has 20% less mineral and three times to 15 times more protein than normal enamel.2
