Sumario:BACKGROUND: Molar incisor hypomineralization (MIH) is a developmental defect. The prevalence of MIH ranges widely from 2.4% to 40.2%. AIM: This study was under taken to determine the prevalence of MIH in 7–9-year-old children of Bengaluru City, India. MATERIALS AND METHODS: A cross-sectional epidemiological study was conducted in a representative sample of 2500 school children aged 7–9 years of Bengaluru, India. Oral examination was carried out by a single trained calibrated examiner under natural daylight. RESULTS: Twelve children (0.48%) were diagnosed with MIH. A total of 68 teeth were observed with MIH. All four first permanent molars were affected in 50% of children. In the molar group, mandibular molars (29.41%) were more frequently affected than maxillary molars (27.94%). CONCLUSION: The prevalence of MIH in 7–9-year-old children of Bengaluru was 0.48%, with no gender predilection.
