概括
使用叶/牙体积比率 (PV/TV) 来进行形光束计算机断层扫描 (CBCT) 的牙年龄估计显示,与时间年龄有很强的负相关性. 这种方法在法医和人类学应用中提供了一个适度可靠的年龄预测工具.
科学领域:
- 法医人类学 法医人类学
- 放射学 放射学是一门学科.
- 牙医年龄估计 牙科年龄估计
背景情况:
- 在法医和人类学背景下,估计时间表年龄至关重要.
- 纸/牙体积比 (PV/TV) 是衰老的潜在指标.
- 圆束计算断层扫描 (CBCT) 提供了牙结构的详细3D成像.
研究的目的:
- 为了估计使用PV/TV比率在下式犬牙的时间表年龄.
- 评估PV/TV比率与时间表年龄之间的相关性.
- 评估基于CBCT的PV/TV比率对年龄估计的可靠性.
主要方法:
- 对240个年龄在17-72岁之间的个体的CBCT扫描进行了追溯分析.
- 使用3D切片软件测量肉和牙体积.
- 使用皮尔森相关性和线性回归计算PV/TV比率并评估与年龄的相关性.
主要成果:
- 在PV/TV比率与年龄之间发现了强烈的负相关性 (r = -0.710,p < 0.001).
- 回归模型实现R2值为0.549 (男性),0.455 (女性) 和0.504 (总样本).

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...

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
