Access to dental healthcare services is a major determinant of dental health in communities. This meta-analysis was conducted to estimate the global prevalence of need and unmet need dental healthcare in adolescents. PubMed, Web of Sciences and Scopus, were searched by June 2018. The summary measures included the prevalence of met and unmet dental health needs. Meta-analysis was performed using the inverse variance method to obtain the pooled summary measure. Out of 41661 retrieved articles, 57 articles were ultimately included. The pooled prevalence of orthodontic treatment needs was 46% (95% CI: 38, 53), general treatment needs 59% (95% CI: 42, 75), periodontal treatment needs 71.0% (95% CI: 46.0, 96.0), and malocclusion treatment needs 39.0% (95% CI: 28.0, 50.0). The pooled prevalence of unmet dental healthcare needs was 34% (95% CI: 27.0, 40.0). The highest and lowest prevalence of unmet dental healthcare needs was related to South-East Asia and the Europe respectively. The prevalence of dental healthcare needs was higher in the countries of the Americas and Europe than in other world health organization (WHO) regions. Moreover, the prevalence of unmet needs was higher in South-East Asia and Africa than in other WHO regions.
