概括
这项研究显示,单根前牙,单通道 (Vertucci Type I) 在也门人群中最常见. 虽然存在一些变异,但根管形态中的性别差异和双边对称性并不显著.
科学领域:
- 牙科 牙科是指牙科的专业.
- 牙周内科医院 牙周内科医院 牙周内科医院
- 牙科解剖学 牙科解剖学
背景情况:
- 有效的根管治疗 (RCT) 取决于对牙内部解剖学的彻底了解.
- 根管形态的变化可能会使牙周内科手术复杂化.
研究的目的:
- 在也门人群中对前牙的根管形态进行分类.
- 在根管解剖学中识别基于性别的变异.
- 在相邻的象限中评估根管形态的双边对称性.
主要方法:
- 使用圆束计算断层扫描 (CBCT) 扫描对2935颗前牙 (1502颗大,1433颗下) 的分析.
- 根管形态的分类基于已建立的系统 (例如,Vertucci).
- 使用Chi-square测试进行统计比较,以评估性别和对称性变化.
主要成果:
- 在前牙和下前牙中观察到具有单通道 (Vertucci Type I) 的单根牙占主导地位.
- 特殊的变异,如Vertucci III型和未分类的 (NC) 形态,在上犬中被发现.
- 前部显示Vertucci类型I,II,V和VII,以及较新的NC分类.
- 两根下犬 (NC Vertucci) 已被确定.
- 根和管道形态的基于性别的变化在统计学上是无意义的.
- 在大牙 (99.2%) 中发现了高双边对称性,在下牙 (84.5-86.5%) 中发现了显著对称性.
结论:
- 单根前牙与单通道 (Vertucci Type I) 是也门人群中最常见的根通道形态.
- 在这个群体中,性别不会显著影响前牙根管形态.
- 高双边对称性是前牙根运河解剖学在也门人口的一个特征.
- 艾哈迈德等人. 艾哈迈德等人. 这种分类系统有效地描述了双根牙.

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...
