# Incidence and treatment for hypomineralization of incisor and molar among school going Indian children

## TL;DR

This study examines the prevalence and treatment needs for molar incisor hypomineralization in Indian schoolchildren, finding a notable incidence and higher impact on mandibular molars.

## Contribution

The study provides new prevalence data and treatment requirements for MIH in Indian children, highlighting gender and molar-specific trends.

## Key findings

- The overall prevalence of MIH was 7.9% among 3030 school-going children.
- Mandibular molars showed a higher incidence compared to maxillary molars.
- Preventive therapy was most needed for mandibular left first molars at 5.4%.

## 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.
