概括
大第一个根的解剖学有很大的差异. 圆束计算机断层扫描 (CBCT) 揭示了根长度,道解剖学 (维图奇II和IV类型) 之间的明显关系,以及Mesio-Buccal (MB) 根通道之间的距离 (MB1-MB2孔间距离).
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:
- 大第一个 (MFM) 的Mesio-Buccal (MB) 根经常呈现复杂的内部解剖学.
- 了解MB根管形态对于成功的内牙治疗至关重要.
- 圆束计算断层扫描 (CBCT) 提供了对根管系统的详细见解.
研究的目的:
- 分析上第一的MB根中的形态关系.
- 用Vertucci的分类来对道配置进行分类.
- 为了研究MB根长度,MB1-MB2孔间距离 (IOD) 和通道类型之间的关联.
主要方法:
- 分析了133个上第一牙和两个MB通道的CBCT扫描.
- 牙的分类是根据Vertucci的道配置系统进行的.
- 用SPSS软件记录和统计分析了MB根长度和MB1-MB2 IOD的测量结果.
主要成果:
- 型IV运河配置是最常见的 (59.4%),其次是II型 (40.6%).
- 在II型 (12.8±0.42毫米) 和IV型 (9.26±0.21毫米) 运河之间观察到MB根长度的显著差异.
- 在II型 (2.4±0.47毫米) 和IV型 (3.8±0.21毫米) 通道之间发现了MB1-MB2 IOD的显著差异.
结论:
- MB根长度和MB1-MB2 IOD与上第一牙的运河类型有显著的关联.
- 这种对MB根管形态的详细理解可以提高内牙科手术的可预测性和成功率.
- 临床医生应该考虑这些形态差异在内牙治疗规划上第一个牙.

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...
