Abstract：
UNASSIGNED: Age estimation for sporting activities, legal age determination and migration purpose is oftentimes essential, which makes the need for a scientifically proven method of age estimation an important aspect of medical practice. Forensic odontology is an essential aspect of forensic practice and may be a veritable tool in age estimation.
UNASSIGNED: The objective of this study was to evaluate the usefulness of orthopantomograms (OPG) in age estimation among selected Nigerians.
UNASSIGNED: A retrospective assessment of 202 OPGs was done to review the visibility of the periodontal ligament of third molars with completed root formation according to the methods described by Olze et al (2010). Individual ages were then calculated by deducting date of exposure from the date of birth recorded in years. Mean age with standard deviation were calculated for each group.
UNASSIGNED: Assessing the minimum and maximum age at which each of the stages of the radiographic visibility of the periodontal ligament as seen on the OPGs revealed that there was a gradual increase in the age at which the stage increment occurred, with a few exceptions. Comparison of the radiographic visibility of the periodontal ligament revealed that males tend to achieve early periodontal visibility stages compared to females, but the reverse was observed in later stages. Age 17 is more than likely attained in any person found within stages 1 to 3 as the minimum age found in these stages were above 17 years.
UNASSIGNED: With a few exceptions, the assessment of periodontal ligament visibility on OPGs can adequately predict the age of individuals. Thus, the use of this method may need to be combined with other methods in accurate determination of dental age in instances of forensic age estimation.

摘要：
■体育活动的年龄估计，法定年龄的确定和移民目的往往是必不可少的，这使得需要科学证明的年龄估计方法的医疗实践的一个重要方面。法医牙本质学是法医实践的重要方面，可能是年龄估计的名副其实的工具。
■这项研究的目的是评估正像图（OPG）在选定的尼日利亚人年龄估计中的有用性。
■根据Olze等人（2010）描述的方法，对202个OPG进行了回顾性评估，以回顾第三磨牙牙周膜的可见性，并完成了牙根形成。然后通过从以年份记录的出生日期中扣除暴露日期来计算个人年龄。计算每组的平均年龄和标准偏差。
■评估在OPGs上看到的牙周膜的射线照相可见性的每个阶段的最小和最大年龄，表明该阶段增加的年龄逐渐增加，除了少数例外。牙周膜的射线照相可见性比较显示，与女性相比，男性倾向于达到早期牙周可见性阶段，但在后期观察到相反的情况。在第1至第3阶段中发现的任何人都可能达到17岁，因为在这些阶段中发现的最低年龄超过17岁。
■除了少数例外，在OPG上评估牙周膜的可见性可以充分预测个体的年龄。因此，在法医年龄估计的情况下，这种方法的使用可能需要与其他方法相结合，以准确确定牙齿年龄。
