The purpose of the present study was to explore the potential application of radiographic visibility of the root pulp in lower third molars in a northern Chinese population, in order to determine if this methodology can be used to prove whether a person has surpassed the thresholds of 18 and 21 years of age. A total of 1300 orthopantomograms comprising equal numbers of females and males evenly distributed between the ages of 15 and 40 years were analyzed. The radiographic visibility of the root pulp of the lower third molars was assessed using the stages described by Olze et al. (2010). Stage 1 first appeared at 19.25 years in males and at 20.73 years in females. The earliest appearance of stage 2 happened at 22.33 years in males and at 22.41 years in females. Stage 3 was achieved first at 26.45 years in males and at 27.66 years in females. It was concluded that stages 1, 2, and 3 can be used to show that a person is over 18 years of age. If stages 2 or 3 are determined, it is possible to prove that an individual has already attained the age of 21 years.
本研究的目的是探讨中国北方人群下颌第三磨牙牙髓影像学可见性的潜在应用，以确定该方法是否可用于证明一个人是否已超过18岁和21岁的阈值。共分析了1300张全景片，其中男女数量相等，年龄均匀分布在15至40岁之间。使用Olze等人（2010年）描述的阶段来评估下颌第三磨牙牙髓的影像学可见性。1期首次出现在男性的19.25岁和女性的20.73岁。2期最早出现在男性的22.33岁和女性的22.41岁。3期首先在男性的26.45岁和女性的27.66岁达到。得出的结论是，1期、2期和3期可用于表明一个人超过18岁。如果确定为2期或3期，则有可能证明一个人已经达到21岁。
