Introduction: Molar Incisor Hypomineralisation (MIH) is a condition where one or more first permanent molars with or without permanent incisors are hypomineralised due to disturbances during the maturation phase. Aim: To determine the prevalence, severity and treatment need of MIH among 8-12-year-old school going children in Cuttack, Odisha. Materials and Methods: A cross-sectional epidemiological survey was conducted, including 1525 students, using diagnostic criteria established by the European Academy of Paediatric Dentistry (EAPD) 2003. Two calibrated examiners examined the children using artificial light. A descriptive analysis of the prevalence and distribution of the clinical recordings was performed using the Statistical Package for Social Sciences, version 17.0 (SPSS Inc., Chicago, IL, USA). Results: A total of 87 children (5.7%) were found to have MIH. Boys showed higher prevalence (57.4%) compared to girls (42.4%). Mandibular molars and maxillary incisors were found to be affected more frequently compared to other teeth. Conclusion: MIH is more prevalent in boys than girls and mandibular molars are affected more frequently than maxillary molars. Hypomineralised molars are more susceptible towards developing dental caries than molars which are not affected by the condition. Molars affected by this condition need wide spectrum of treatment ranging from preventive care, pit and fissure sealant application, restoration, pulp therapy and extraction. Early intervention of these teeth can reduce the complications and expenses incurred towards dental treatment.
