- 牙科学
- 牙周内科
- 口腔解剖学
背景情况:
- 根管形态变化对于成功的根管治疗 (RCT) 是至关重要的.
- 不确定的解剖变异可能导致内牙治疗失败.
- 圆束计算断层扫描 (CBCT) 对于详细的根管分析至关重要.
研究的目的:
- 确定上第二前 (Mx2P) 中根管结构的频率和分布.
- 研究Mx2P的根管形态与性别之间的关联.
- 通过详细的解剖学理解来加强内脏治疗计划.
主要方法:

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...

Assessment of the Mouth
404
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.
