概括
使用牙科放射图的法医年龄估计对于长期使用类固醇的人来说可能不准确. 脉腔收缩,一个常见的指标,在这些人中出现过早,导致严重的年龄估计错误.
科学领域:
- 法医牙科 法医牙科
- 放射学 放射学是一门学科.
- 内分泌学 在内分泌学.
背景情况:
- 牙科放射图用于通过分析与年龄相关的脉腔收缩来进行法医年龄估计.
- 长期使用类固醇可以导致皮质腔过早收缩,使准确的年龄评估复杂化.
- 这种现象在年轻人群中并不常见,需要仔细解释.
研究的目的:
- 调查长期使用类固醇的法医年龄估计的准确性.
- 为了评估类固醇诱导的脉腔收缩对年龄估计的影响,使用犬类X射线图.
- 为了确定肉皮面积与牙总面积的比率是否可以可靠地估计这一群体的年龄.
主要方法:
- 研究了使用双酸盐预防类固醇骨质疏松症的8名患者 (年龄在30至40岁之间).
- 获得了狗牙放射图,以测量肉和牙总面积.
- 来自一般日本人口的回归公式被用来估计年龄.
主要成果:
- 在类固醇使用者的估计年龄和年代年龄之间观察到显著的差异.
- 平均绝对误差为19.24年 (上犬类) 和17.69年 (下犬类).
- 根的平均平方误差为23.18年 (上犬) 和20.00年 (下犬).
结论:
- 标准的法医年龄估计方法对于长期使用类固醇的人来说是不可靠的,原因是脉腔过早收缩.
- 脉腔收缩与其他法医发现不一致,可能表明使用类固醇,需要谨慎地估计年龄.
- 这一发现有助于在法医调查期间预测身份不明个人的医疗背景.

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
