Molar-incisor hypomineralisation (MIH) assessment vs None (descriptive prevalence review; subgroup analyses by urban/rural status, country and year)

MIH prevalence · School-aged children in the United Arab Emirates (Dubai)

MIH prevalence among school-aged children in Dubai ranged from 7.6% to 27.2% across two studies, higher in females and low-socioeconomic-class schools (narrative synthesis; not GRADE-rated).
