Molar Incisor Hypomineralization
The Journal of Contemporary Dental Practice, 2016 ABSTRACTMolar incisor hypomineralization (MIH) is a developmental defect affecting teeth. High prevalence rates of MIH and its clinical implications are significant for both the patients and clinicians. A wide variation in defect prevalence (2.4–40.2%) is reported. It seems to differ with regions and various birth cohorts. Some of the recent prevalence
