Dental management strategies for Molar Incisor Hypomineralization

Background: Molar Incisor Hypomineralization (MIH) is defined as a hypomineralization of systemic origin that can affect all permanent first molars and, in most cases it can also affect the permanent incisors. Objective: The aim of this review was to describe the various options available to treat and restore MIH-affected molars. Results: MIH is a developmental, qualitative enamel defect caused by reduced mineralization of the inorganic enamel components, leading to enamel discoloration and defects in the affected teeth. MIH in permanent molars is usually associated with caries and intense pain, and children often become disruptive during MIH treatment due to the challenges associated in achieving proper anesthesia of the affected teeth. Conclusion: Early detection and appropriate therapy can prevent severe complications and improve both masticatory function and esthetics. The treatment of MIH varies from a simple procedure, such as a controlled clinical eruption, to extensive and recurrent treatments in more severe cases.
