Abstract
The presence of molar incisor hypomineralization (MIH) raises the likelihood of enamel degradation, which in turn raises the risk of plaque buildup and dental caries. Individuals impacted by this illness frequently incur large long-term costs. Therefore, it is of interest to evaluate prevalence and treatment need of MIH in school going children. Hence, 3030 school going students were included in this study. Considering the WHO 1997 guidelines for caries severity and the requirement of therapy for the damaged teeth and criteria for MIH, a full mouth visual assessment of moist teeth was conducted for every student. The overall prevalence of MIH was 174 (7.9%). Preventive caries restricting therapy was needed in 42(6.2%) maxillary right first molar,30(4.5%) maxillary left first molar, 30 (4.5%) mandibular right first molar, 36 (5.4%) in mandibular left first molar. Data shows that an incidence rate of 7.4 percent was noted, with a larger propensity among male children and a predominant impact on mandibular molars.
