Prevalence and Predictors of Molar Incisor Hypomineralization (MIH) among Rural Children in Northern Iran

Molar incisor hypomineralization (MIH) is an enamel defect in permanent first molar and inci-sor teeth. The defects may vary from white, to yellow-brown demarcated opacities that may easi-ly break (post-eruptive breakdown) and results in extensive caries or early extraction of the teeth. The unaesthetic appearance of anterior teeth, sensitivity, pain, and difficulties in achieving local anesthesia, and providing proper restorations are of MIH complications (1).
