Introduction Assessing the dental development plays a key role in forensic dentistry. Dental age based on stages of teeth mineralization can be assessed by using different methods, and is especially useful in subadults. Chaillet's method was developed based on the Demirijan's method. In this study, we aimed to study the applicability of Chaillet's method in subadults.
We performed systematic reviews and meta-analysis of observational studies published in English using the following databases Pubmed, Web of Science, Embase and Scopus, with a timeframe between 2013 and 2019.
The difference between chronological age and dental age was calculated separately, for each gender. In girls, the method underestimated the age with an average difference between dental and chronological of 0.83 years (CI= [-1.34; -0.31]), with significant heterogeneity and publication bias. In boys, the method underestimated the age with an average difference between dental and chronological of 0.64 years (CI= [-1.28; 0.01)], with significant heterogeneity and publication bias. Chaillet's method showed an advanced dental maturity in European boys by 0.35 years [-0.85; 1.55], while it underestimated the age in South Asian boys by -1.03 (CI= [-1.60; -0.46]). For girls this method showed a delayed dental development for both regions, with a rather smaller difference for Europeans of -0.06 years (CI= [0.91; 0,78]) compared to South Asian girls: -1.19 years (CI= [-1.86; -0.51.
Dental age estimation provided by the Chaillet's method showed an age overestimation in both genders, in most studies geographic groups.
引言 评估牙齿发育在法医牙科学中起着关键作用。基于牙齿矿化阶段的牙龄可以通过不同方法进行评估，在未成年人中尤为有用。Chaillet方法是在Demirijan方法的基础上发展而来的。在本研究中，我们旨在探讨Chaillet方法在未成年人中的适用性。
我们使用以下数据库（PubMed、科学网、Embase和Scopus）对2013年至2019年期间以英文发表的观察性研究进行了系统评价和荟萃分析。
按性别分别计算实际年龄与牙龄之间的差异。在女孩中，该方法低估了年龄，牙龄与实际年龄的平均差异为0.83岁（CI = [-1.34；-0.31]），存在显著的异质性和发表偏倚。在男孩中，该方法低估了年龄，牙龄与实际年龄的平均差异为0.64岁（CI = [-1.28；0.01]），存在显著的异质性和发表偏倚。Chaillet方法显示欧洲男孩的牙齿成熟度提前了0.35岁[-0.85；1.55]，而在南亚男孩中则低估了1.03岁（CI = [-1.60；-0.46]）。对于女孩，该方法在两个地区均显示牙齿发育延迟，与南亚女孩相比，欧洲女孩的差异较小，为-0.06岁（CI = [0.91；0.78]）：-1.19岁（CI = [-1.86；-0.51]）。
在大多数地理组的大多数研究中，Chaillet方法提供的牙龄估计在两性中均显示年龄高估。
