Cranial suture closure has long been recognized as a character of human development related to aging. For this reason, it has been utilized for various forensic and archaeological studies to determine the age of an unidentified/or skeletonized individuals. Various cadaveric studies have established the role of lambdoid suture in age estimation, but not routinely practiced. The objective is to establish if any correlation exists between individual's age and lambdoid sutures closure status (ectocranially) in mortals through modified reverse panoramic radiograph (RPRg).
Total number of 85 subjects, 25 years and beyond were included in the study, and divided into four groups with an age interval of 10 years. Assessment of lambdoid suture closure was done according to Frederic Rating Scale on modified RPRg. Data obtained was subjected to statistical analysis using Spearman's correlation test.
A significant difference was observed between the age group and suture closure. Correlation coefficient of 0.570 was obtained, and was interpreted as a good correlation between the age and suture closure status with a P value of <0.001.
Lambdoid suture can be very effective and practical tool for age assessment in mortals through modified RPRg (ectocranially).
颅骨缝闭合长期以来一直被认为是与衰老相关的人类发育特征。因此，它已被用于各种法医和考古研究，以确定身份不明或骨骼化个体的年龄。各种尸体研究已经确定了人字缝在年龄估计中的作用，但尚未常规应用。目的是通过改良的反向全景X线片（RPRg）确定凡人个体年龄与人字缝闭合状态（颅外）之间是否存在任何相关性。
本研究纳入了85名年龄在25岁及以上的受试者，并将其分为四组，年龄间隔为10年。根据改良RPRg上的弗雷德里克评分量表对人字缝闭合情况进行评估。对获得的数据进行Spearman相关性检验的统计分析。
年龄组与缝闭合之间观察到显著差异。获得的相关系数为0.570，解释为年龄与缝闭合状态之间具有良好的相关性，P值<0.001。
通过改良的RPRg（颅外），人字缝可以成为凡人年龄评估的非常有效和实用的工具。
