Multiple third molar development registration techniques exist. Therefore the aim of this study was to detect which third molar development registration technique was most promising to use as a tool for subadult age estimation. On a collection of 1199 panoramic radiographs the development of all present third molars was registered following nine different registration techniques [Gleiser, Hunt (GH); Haavikko (HV); Demirjian (DM); Raungpaka (RA); Gustafson, Koch (GK); Harris, Nortje (HN); Kullman (KU); Moorrees (MO); Cameriere (CA)]. Regression models with age as response and the third molar registration as predictor were developed for each registration technique separately. The MO technique disclosed highest R(2) (F 51%, M 45%) and lowest root mean squared error (F 3.42 years; M 3.67 years) values, but differences with other techniques were small in magnitude. The amount of stages utilized in the explored staging techniques slightly influenced the age predictions.
存在多种第三磨牙发育登记技术。因此，本研究的目的是检测哪种第三磨牙发育登记技术最有希望用作亚成年人年龄估计的工具。在收集的1199张全景X光片上，按照九种不同的登记技术[格莱泽、亨特（GH）；哈维科（HV）；德米尔坚（DM）；朗帕卡（RA）；古斯塔夫森、科赫（GK）；哈里斯、诺特杰（HN）；库尔曼（KU）；穆里斯（MO）；卡梅里埃（CA）]对所有现存第三磨牙的发育情况进行登记。分别针对每种登记技术建立了以年龄为响应变量、第三磨牙登记情况为预测变量的回归模型。MO技术显示出最高的R²值（女性为51%，男性为45%）和最低的均方根误差（女性为3.42岁；男性为3.67岁），但与其他技术的差异幅度较小。所探索的分期技术中使用的阶段数量对年龄预测略有影响。
