概括
使用伦敦牙发育图谱 (London Atlas of Tooth Development) 的牙科年龄估计在3-12岁时最准确. 虽然没有一个单一的牙是最适合所有年龄段的,但第二牙提供了最一致的结果来预测时间表年龄.
科学领域:
- 法医人类学 法医人类学
- 儿科牙科 儿科牙科
- 放射学 放射学是一门学科.
背景情况:
- 牙年龄估计对于评估牙发育和预测年龄至关重要.
- "伦敦牙发育图谱"估计年龄是年龄区间内的单一中点值.
研究的目的:
- 为了确定最佳的牙阶段,单个牙或牙组合,使用伦敦地图来准确估计年龄.
- 为了评估不同牙及其对时间年龄的组合的预测准确度.
主要方法:
- 分析了946张全景放射 (3至16岁) 和82323张正在发育的永久牙.
- 牙年龄 (DA) 使用伦敦地图应用计算;平均差异 (MD) 和平均绝对差异 (MAD) 计算.
- 线性回归评估了单个和组合牙的预测强度和对线性 (VIF).
主要成果:
- 个人牙阶段为3至12岁儿童的最佳估计年龄.
- 第二前,犬和中央切口器显示出高度的对线性,而它们的排除并没有改善年龄预测.
- 没有一个单一的牙在所有个体年龄类别中一致预测年龄.
结论:
- 年龄估计的准确性因牙和年龄类别而异;没有单一的牙是普遍最好的.
- 两个下巴的第二牙表现出最小的平均差异,平均绝对差异和较低的差异膨胀因子,表明更高的可靠性.
- 该研究强调了单一牙评估在所有儿科年龄范围内的全面年龄预测的局限性.

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...
