Abstract

Pursuing a proficient age estimation methodology introducing novel radiographic methods remains an ongoing and demanding aspect of forensic and medicolegal research. In 2017, Roberts GJ et al. (J Forensic Sci 62(2):351-4, 2017) described a new radiographic method, i.e., root canal width (RCW) patterns to assign a subject to above 18-year-age threshold. Since then, few researchers have investigated the validity of this radiographic method in other populations. The present study aimed to test the usefulness of these RCW patterns in predicting 18 years in a sample of South Indian juveniles and sub-adults aged between 16 and 23. Descriptive analysis revealed that pattern-A was initially observed at a minimum age of 16.08 and 16.22 years in males and females. Pattern-B at 16.31 years in males and 16.22 years in females, while pattern-C was initially recorded at 18.73 years in males and 19.01 years in females, respectively. In summary, if an individual, regardless of sex, exhibits a fully-formed (apex closed) mandibular first, second, and third molars and concurrently displays RCW-C, there is a strong likelihood that the person has exceeded the legally relevant age of 18 years. However, due to higher rate of technically unacceptable errors (adults wrongly identified as individuals below 18 years), reliance on this method alone should be restricted, and it is advisable to combine it with other methods.

下颌臼齿根管宽度在预测南印度裔青少年和亚成年人 18 岁法定年龄界限中的作用:一项正畸研究。
在法医和法医研究中,引入新型放射摄影方法以追求熟练的年龄估计方法仍然是一个持续且要求较高的方面。2017 年,Roberts GJ 等人(J Forensic Sci 62(2):351-4, 2017)描述了一种新的放射摄影方法,即根管宽度(RCW)模式,用于将受试者归入 18 岁以上的年龄阈值。此后,很少有研究人员在其他人群中调查这种放射学方法的有效性。本研究旨在测试这些 RCW 模式在南印度 16 至 23 岁青少年和亚成年人样本中预测 18 岁的实用性。描述性分析表明,模式-A 在男性和女性的最低年龄分别为 16.08 岁和 16.22 岁时出现。模式 B 的男性最低年龄为 16.31 岁,女性最低年龄为 16.22 岁,而模式 C 的男性最低年龄为 18.73 岁,女性最低年龄为 19.01 岁。总之,如果一个人,无论性别,下颌第一、第二和第三磨牙完全成形(牙尖闭合),同时显示 RCW-C,那么这个人很有可能已经超过了法律规定的 18 岁。然而,由于技术上不可接受的错误率较高(将成年人错误地识别为 18 岁以下的个人),因此应限制单独依赖这种方法,最好将其与其他方法结合使用。

期刊介绍: The International Journal of Legal Medicine aims to improve the scientific resources used in the elucidation of crime and related forensic applications at a high level of evidential proof. The journal offers review articles tracing development in specific areas, with up-to-date analysis; original articles discussing significant recent research results; case reports describing interesting and exceptional examples; population data; letters to the editors; and technical notes, which appear in a section originally created for rapid publication of data in the dynamic field of DNA analysis.
