The present study used 127 extracted teeth from people aged 16 to 90 years old. The aim of this research was to verify the reliability of the method using a single dental parameter based on the correlation of the radicular cementum thickness and the chronological age of the subject. The thickness was measured both on the lingual side and on the vestibular side of the tooth, at two different levels: apex and one third of the root length from the apex. The data were reported through a Cartesian graph with the X-axis showing the cementum thickness and the Y-axis showing the subject's age. The correlation between age and the increase of the cementum thickness is more statistically evident when the measurement is taken at the apex (R2=0.67), in comparison with the measurement taken at approximately one third of the root length from the apex (R2=0.56).
本研究使用了127颗从16至90岁人群中拔除的牙齿。本研究的目的是基于牙根牙骨质厚度与受试者实际年龄的相关性，验证使用单一牙齿参数的方法的可靠性。在牙齿的舌侧和唇侧，于两个不同水平测量厚度：根尖处以及距根尖三分之一牙根长度处。数据通过笛卡尔图呈现，X轴表示牙骨质厚度，Y轴表示受试者年龄。与在距根尖约三分之一牙根长度处进行的测量（R2 = 0.56）相比，在根尖处进行测量时，年龄与牙骨质厚度增加之间的相关性在统计学上更为显著（R2 = 0.67）。
