Background: Molar incisor hypomineralization (MIH) is a systemic enamel defect that affects one to four permanent first molars, sometimes involving associated incisors. It is marked by distinct enamel opacities, which can occasionally result in post eruptive breakdown. The defects are usually asymmetrical, with one molar or incisor potentially showing severe damage, while its corresponding contralateral tooth may appear clinically normal or display only slight imperfections. This cross- sectional study was conducted to analyze the prevalence of MIH and to assess its association with Hypomineralised Second Primary Molar (HSPM) among children of preadolescent age group (9-12 years) in a city in Western U.P.
Materials and Methods: Dental examination of children was done in schools using a mouth mirror and explorer under portable light. Occlusal, buccal and palatal surfaces of permanent first molars and second primary molars along with labial and lingual surfaces of maxillary and mandibular incisors were examined by a single examiner using European Archives of Pediatric Dentistry (EAPD) criteria for MIH diagnosis.
Results: The prevalence of MIH and HSPM in this cross-sectional study was found to be 19.5% (74/380) and 6.8% (26/380) respectively.
Conclusion: Only molars were affected in about 32.43% (24/74) of MIH cases and both molars and incisors were affected in 67.5% (50/74) of cases. There was no significant association of sex and age with MIH (p<0 P=0.00).>
