OBJECTIVES
To investigate the age-related changes of the mandibular third molar root pulp visibility in individuals in East China, and to explore the feasibility of applying this method to determine whether an individual is 18 years or older.
METHODS
A total of 1 280 oral panoramic images were collected from the 15-30 years old East China population, and the mandibular third molar root pulp visibility in all oral panoramic images was evaluated using OLZE 0-3 four-stage method, and the age distribution of the samples at each stage was analyzed using descriptive statistics.
RESULTS
Stages 0, 1, 2 and 3 first appeared in 16.88, 19.18, 21.91 and 25.44 years for males and in 17.47, 20.91, 22.01 and 26.01 years for females. In all samples, individuals at stages 1 to 3 were over 18 years old.
CONCLUSIONS
It is feasible to determine whether an individual in East China is 18 years or older based on the mandibular third molar root pulp visibility on oral panoramic images.
目的
研究华东人群下颌第三磨牙牙髓腔可见度随年龄的变化，探讨该方法应用于判断个体是否年满 18 岁的可行性。
方法
收集华东地区 15-30 岁人群的 1280 张口腔全景片，采用 OLZE 0-3 四阶段法评估所有口腔全景片中下颌第三磨牙牙髓腔可见度，并采用描述性统计分析各阶段样本的年龄分布。
结果
男性下颌第三磨牙牙髓腔可见度分别在 16.88、19.18、21.91 和 25.44 岁时出现 0 期、1 期、2 期和 3 期，女性则分别在 17.47、20.91、22.01 和 26.01 岁时出现。所有样本中，处于 1 期至 3 期的个体均年满 18 岁。
结论
基于口腔全景片下颌第三磨牙牙髓腔可见度，判断华东地区个体是否年满 18 岁是可行的。
