Abstract

Aim: The aim of the present study was to investigate the prevalence and etiology of molar–incisor hypomineralization (MIH) in 8-to 16-year-old children from town (Baddi) of Himachal Pradesh. Materials and methods: A cross-sectional study was conducted with 2000 children from various schools of Baddi. Molar–incisor hypomineralization was diagnosed on the basis of EAPD 2003 criteria revised in 2009. Results: Prevalence of MIH found was to be 2.9%. Demarcated opacities were predominant among all the defects. Postnatal illnesses were highly associated with MIH. The prevalence of dental caries reported in MIH patients was 82.7%. Conclusion: Postnatal illnesses are significantly associated with MIH. Molar–incisor hypomineralization predisposes the tooth to dental caries.
