A multi-factorial method for estimating age was devised based on the development of the 3rd molar tooth, the medial clavicular epiphysis, and the spheno-occipital synchondrosis, using multiple regression as the means to construct age estimation formulae and CT scanning as the imaging modality. The sample consisted of approximately 600 individuals from a contemporary Australian population, between the ages of 15 and 25 years, who were admitted to the Victorian Institute of Forensic Medicine, Melbourne, Australia, for the purposes of medico-legal death investigation. Results show that the spheno-occipital synchondrosis does not contribute to the age estimation model for this age cohort. The regression computation for the 3rd molar tooth and medial clavicle, when combined into a single multiple regression calculation, provides a robust model with tighter age ranges at the 95% confidence interval (CI) than when each age marker is used individually. This research provides a method to estimate age for unknown age Australian individuals in the problematic age group of 15-25 years with greater precision than previously possible.
本研究基于第三磨牙、锁骨内侧骺、蝶枕联合的发育情况，采用多元回归构建年龄估算公式，并结合 CT 扫描作为影像学方法，制定了一种多因素年龄估算方法。该样本由大约 600 名年龄在 15 至 25 岁之间的当代澳大利亚人群组成，他们因法医学死亡调查的目的被送往澳大利亚墨尔本维多利亚法医研究所。结果表明，蝶枕联合对于该年龄组的年龄估算模型没有贡献。当将第三磨牙和锁骨内侧联合的回归计算结合为单个多元回归计算时，与单独使用每个年龄标志物相比，该模型提供了更紧密的年龄范围，置信区间 (CI) 为 95%。本研究提供了一种方法，可更精确地估算 15-25 岁这一年龄段未知年龄的澳大利亚个体的年龄，优于以往的方法。
