概括
在沙特下第一个牙中,中间的 mesial 通道是罕见的,但地峡是常见的,特别是在 mesial 根. 圆束计算断层扫描 (CBCT) 有助于识别这些复杂的根管解剖,以获得更好的内牙治疗.
科学领域:
- 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
- 放射学 放射学是一门学科.
背景情况:
- 成功的内牙治疗需要了解根管形态和消毒.
- 解剖学变异,如额外的通道和峡谷,可以影响临床结果.
- 这项研究侧重于沙特人口下第一个形态.
研究的目的:
- 评估沙特人下第一个的根和道形态.
- 为了确定中部月经通道 (MMCs) 和地峡的流行率和配置.
- 评估圆束计算机断层扫描 (CBCT) 在识别这些特征中的作用.
主要方法:
- 552个CBCT扫描的回顾性分析,其中167个扫描符合资格标准.
- 包括来自沙特患者的322个下第一个牙,这些患者的牙完全形成.
- 使用韦恩系统对根运河配置进行分类,并记录MMC,峡谷和双边对称.
主要成果:
- 大多数牙有两个根 (75.5%);24.5%有两个远端根.
- 梅西叶根主要是Weine II型 (50.9%) 和III型 (48.1%).
- 中间月经通道 (MMCs) 是罕见的 (0.98%),而地峡是非常普遍的 (82%),在III型月经根 (72.3%).
结论:
- 在沙特下第一个牙中,中部 mesial 通道并不常见.
- 频繁地观察到月经根中的地峡,突出显示了预测道间通信的必要性.
- CBCT成像对于精确检测和治疗计划复杂的根管解剖学至关重要.

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...

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...
