Estimation of age of an individual can be performed by evaluating the pattern of dental development. A dataset for age estimation based on the dental maturity of a French-Canadian population was published over 35 years ago and has become the most widely accepted dataset. The applicability of this dataset has been tested on different population groups.
To estimate the observed differences between Chronological age (CA) and Dental age (DA) when the French Canadian dataset was used to estimate the age of different population groups.
A systematic search of literature for papers utilizing the French Canadian dataset for age estimation was performed. All language articles from PubMed, Embase and Cochrane databases were electronically searched for terms 'Demirjian' and 'Dental age' published between January 1973 and December 2011. A hand search of articles was also conducted.
A total of 274 studies were identified from which 34 studies were included for qualitative analysis and 12 studies were included for quantitative assessment and meta-analysis. When synthesizing the estimation results from different population groups, on average, the Demirjian dataset overestimated the age of females by 0.65 years (-0.10 years to +2.82 years) and males by 0.60 years (-0.23 years to +3.04 years).
The French Canadian dataset overestimates the age of the subjects by more than six months and hence this dataset should be used only with considerable caution when estimating age of group of subjects of any global population.
通过评估牙齿发育模式可以对个体年龄进行估计。一个基于法裔加拿大人牙齿成熟度的年龄估计数据集在35年前就已发布，并已成为被广泛接受的数据集。该数据集的适用性已在不同人群中进行了测试。
当用法裔加拿大人数据集来估计不同人群的年龄时，估计实际年龄（CA）与牙齿年龄（DA）之间观察到的差异。
系统检索利用法裔加拿大人数据集进行年龄估计的文献。对PubMed、Embase和Cochrane数据库中所有语言的文章进行电子检索，查找1973年1月至2011年12月期间发表的包含“德米尔坚”和“牙齿年龄”的文章。还对手头文章进行了检索。
共识别出274项研究，其中34项研究纳入定性分析，12项研究纳入定量评估和荟萃分析。综合不同人群组的估计结果，平均而言，德米尔坚数据集将女性年龄高估了0.65岁（-0.10岁至+2.82岁），将男性年龄高估了0.60岁（-0.23岁至+3.04岁）。
法裔加拿大人数据集将受试者年龄高估了六个多月，因此在估计任何全球人群组的年龄时，应极其谨慎地使用该数据集。
