Molar Incisor Hypomineralization Prevalence in the Schoolchildren of Gannavaram Mandal, Krishna District, Andhra Pradesh, India: A Cross-sectional Study

Abstract

Aim and objectives: To evaluate the prevalence of molar incisor hypomineralization (MIH) in schoolchildren of the ages between 8 and 14 years of Gannavaram Mandal, Krishna district, Andhra Pradesh, India. Materials and methods: A total of 2,250 children of ages between 8 and 14 years were selected randomly from different schools. After obtaining requisite permissions from Mandal Educational Officer (MEO), children was screened for the prevalence of MIH according to European Academy of Paediatric Dentistry (EAPD) 2003 diagnostic criteria and severity for MIH was examined using Wetzel and Reckel scale. Results: Prevalence of MIH was observed to be 2.1% with higher cases of mild severity and with no sex predilection (p > 0.05). Conclusion: Early diagnosis and treatment can significantly reduce complications associated with MIH. Very few studies have been conducted in India and studies encompassing extensive population are warranted to better understand its etiology. Clinical significance: MIH lesions lead to carious development. Hence there is need to identify MIH in children as early as possible to reduce the clinical complications.
