Main Article Content
Abstract
Introduction: The prevalence of Molar Incisor Hypomineralization (MIH) and Hypomineralized Second Primary Molars (HSPM) varies globally and across different states of India. The aim of the study was to assess the prevalence of MIH and HSPM in 7–9-year-old school children in Goa, India.
Methods: Ethical clearance was obtained from the Institutional Ethics Committee and the study was carried out in primary schools across the talukas of Goa state. Molar Incisor Hypomineralization and HSPM were recorded in 7–9-year-old school children as per the data recording sheets suggested by Ghanim et al. The IBM SPSS version 26 software was used for the statistical analysis.
Results: A total of 503 children were examined, out of which 15.71% had MIH and 8.95% had HSPM. Almost half of the affected children showed the simultaneous occurrence of MIH and HSPM.
Conclusions: The prevalence of MIH and HSPM in Goa were found to be within global prevalence limits. Hypomineralized Second Primary Molars may be a warning sign for the occurrence of MIH.
