摘要: Background A method for assessing dental maturity in different populations was first developed 1973 by Demirjian and has been widely used accepted since then. While the accuracy evaluating age using Demirjian’s compared to children’s chronological extensively studied recent years, results currently available remain controversial ambiguous. Methods literature search of PubMed, Embase, Web Science, CNKI CBM databases conducted identify all eligible studies published before July 12th, 2013. Weighted mean difference (WMD) with corresponding 95% confidence interval (95% CI) evaluate applicability estimating children. Results: meta-analysis on 26 a total 11,499 children (5,301 boys 6,198 girls) aged 3.5 16.9 years. Overall, we found that overestimated 0.35 (4.2 months) 0.39 (4.68 years males females, respectively. subgroup analysis revealed girls between ages 5 14 were given estimate significantly more advanced than their age. Differences underestimated actual lower male female 15- 16-year-old subgroups, though significant subgroup. Conclusions method’s overestimation tooth reveals need population-specific standards better rate human maturation.
