目的。本研究的主要目的是利用全景数字成像技术，确定、比较和区分不同年龄段的男性和女性自然牙齿志愿者的下颌骨结构的变化，并确定由此获得的数据在年龄评估中的可靠性，以支持法医意见。

材料与方法。我们对620名志愿者进行了下颌骨的全景数字成像，分四个年龄组：12-18岁、19-40岁、41-60岁和60岁以上。我们测量并分析了下颌角、下颌骨髁突长度、下颌骨分支长度、皮质骨厚度和下颌骨分支切口宽度。数据的处理采用了描述性的统计分析方法，以及双侧学生t检验和双因素方差分析。

结果。角度和四项线性测量显示，所有年龄组之间的差异具有统计学意义（p<0.05），除下颌角外，所有测量都有以下规律：年龄组越大，差异越大。左右两边的所有参数（下颌角、下颌支长度和下颌支切口宽度）都有统计学上的显著差异（p<0.05）。

结论。研究人群中，根据下颌骨的角度和线性测量来估计年龄的可能性已被证实。研究发现，除下颌角外的所有参数都能可靠地确定年龄，年龄越大，所有参数的平均值越大，对于除下颌角外的所有参数，发现有统计学上的显著差异。因此，根据这项研究的结果，可以建议在法医检查中使用除下颌角以外的所有参数进行年龄评估。
