The purpose of this study was to evaluate the reliability of the tooth/pulp ratio method in the process of age estimation at the moment of death in a forensic context and compare it with standard anthropological methods. After the exhumation of mass graves located in sites in Batajnica, Serbia, in 2002 and 2003, skeletal material was thoroughly analyzed by a group of anthropologists and pathologists. As a part of the investigation, orthopantomography (OPG) was performed for each individual. During 2018 these OPGs were reexamined for scientific purposes. Age-at-death was assessed by means of the pulp/tooth ratio method applied to all available lower premolars. Estimated age following standard anthropological methods and chronological age (obtained after DNA identification of victims) was taken from the records. Age estimation using the pulp/tooth ratio and standard methods was compared with chronological age. The pulp/tooth ratio method was accurate in 81.25% of all cases and the standard method was accurate in 56.25% of all cases. The pulp/tooth ratio method of age estimation was found to be applicable and accurate. However, age estimation should be based on all available methods.
本研究旨在评估在法医背景下死亡时进行年龄估计时牙髓/牙齿比例法的可靠性，并将其与标准人类学方法进行比较。2002 年和 2003 年，在塞尔维亚巴塔尼察的墓地发掘出大量坟墓后，一组人类学家和病理学家对骨骼材料进行了彻底分析。作为调查的一部分，对每个人进行了全景 X 光检查（OPG）。2018 年，这些 OPG 被重新用于科学目的。通过应用于所有可用的下前磨牙的牙髓/牙齿比例法来评估死亡时的年龄。根据标准人类学方法和（通过受害者 DNA 识别获得的）实际年龄记录，从记录中获取估计年龄和实际年龄。比较了牙髓/牙齿比例法和标准方法的年龄估计与实际年龄。牙髓/牙齿比例法在所有情况下的准确率为 81.25%，标准方法在所有情况下的准确率为 56.25%。牙髓/牙齿比例法的年龄估计被证明是适用且准确的。但是，年龄估计应该基于所有可用的方法。
