Aims: This systematic review and meta‑analysis aimed to evaluate the pooled prevalence of molar‑incisor hypomineralization (MIH) among children. Methods: Three databases (PubMed, Scopus, and CINAHL) were searched till January 1, 2017, for the prevalence of MIH among children. The heterogeneity of the publications was evaluated using I2 statistics. Two trained reviewers conducted risk of bias assessment with nine item checklist for prevalence studies. Results: Analysis of the included publications revealed a pooled prevalence of 11.24 (confidence interval = 9.23–13.45) with the use of quality effects model. Heterogeneity among the included publications was high. The risk of bias assessment showed that majority of them were in the low‑risk category. Conclusions: MIH is a common problem and one in 10 children could be affected by MIH.
