概括
这项研究验证了巴西第二牙下部的肉质卷变阶段,以估计牙年龄. 结果表明使用这些阶段为年龄门,而不是精确的年龄确定,有助于预测成年年龄.
科学领域:
- 法医人类学
- 牙科学
- 人类学
背景情况:
- 牙年龄估计方法通常依赖于特定的牙,如第三牙.
- 缺少第三可能会限制现有的牙年龄估计技术的适用性.
研究的目的:
- 验证使用根肉质可见度阶段在下面的第二牙来估计牙的年龄.
- 评估该方法在巴西人口中的适用性.
主要方法:
- 分析了1190个年龄在14岁至30岁99岁的人的骨科影像.
- 根肉卷变阶段的分类
- 使用微软Excel和R Studio进行统计分析.
主要成果:
- 预测成年期的准确率达到了72%.
- 第三阶段可靠地表明18岁以上的个体 (100%的概率).
- 阶段0,1和2显示重叠的年龄范围,这表明精确的年龄估计是有限的.
结论:
- 在巴西,下一牙的肉质内变阶段显示出预测成年年龄的潜力.
- 该方法更适合评估年龄门 (例如,达到18岁),而不是确定特定的年龄范围.
- 需要对不同种群进行进一步的研究,以确认种群间的差异和更广泛的适用性.

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

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...

A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

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...
