Study selection Original population-based studies that described the diagnostic criteria of MIH and provided prevalence data or sufficient information that could be used to calculate MIH prevalence. Data extraction and synthesis Two reviewers independently extracted the data. Meta-regression was done using a random effects model for parameters of age, gender and region. Heterogeneity was assessed using I2 statistic. Results Seventy studies were included that encompassed a total of 89,520 people and 10,823 cases of MIH. The pooled global prevalence of MIH was 14.2% (95% CI 12.6-15.8), with South America having the highest prevalence (18%; 95% CI 13.8-22.2) and Africa the lowest (10.9%; 95% CI 4.2-17.6). There was no significant difference between male and female participants. Prevalence of MIH amongst children ten years of age or younger (15.1%, 95% CI 12.1-18.2) was higher than older children (12.1%, 95% CI 8.0-16.3). Conclusions This meta-analysis showed the average global prevalence of MIH as 14.2%. Some geographic regions had higher than average prevalence, which could inform oral health policy in those areas.
