Molar incisor hypomineralisation is an entity to describe enamel defects of the first permanent molars with involvement of one or more incisors due to an underlying systemic cause. Etiological factors include genetics, environmental, medical conditions and systemic factors. These teeth often present as white chalky enamel with post eruptive breakdown. In severe cases, there is a complete loss of enamel. There are other enamel defects which can mimic the appearance of MIH making it difficult to diagnose. Diagnostic criteria have been established by the European Academy of Paediatric Dentistry (EAPD). Early diagnosis is the key to protect and prevent the deterioration of the condition. Children pose with behavioural problems which must be addressed. Preventive strategies in conjunction with restorative therapy can preserve these teeth. Challenges encountered in treating these teeth are improper cavity design, inadequate anesthesia and choice of restorative material. Thus, a deeper understanding of the micro structural changes occurring during amelogenesis will aid in better understanding of the etiology. Upgrading knowledge and skill in using the newer materials will improve the survival rates of the restorations. The purpose of this paper is to highlight the etiology, prevalence, diagnosis, differential diagnosis, challenges faced in treating and management options for successfully dealing with MIH.
