概括
在经过内牙治疗的牙中,有很大比例的牙表现出未经治疗的根通道和周病变,这些病变往往与不充分的冠状密封有关. 圆束计算机断层扫描 (CBCT) 揭示了牙科治疗失败中的这些常见问题.
科学领域:
- 牙周内科医院 牙周内科医院 牙周内科医院
- 放射学 放射学是一门学科.
- 牙科公共卫生 牙科公共卫生
背景情况:
- 内牙治疗的目的是消除内感染,防止再感染.
- 未经治疗的根通道和周围牙病变是内牙治疗失败的潜在指标.
- 冠状封印对于内牙治疗的长期成功至关重要.
研究的目的:
- 为了确定内牙治疗牙中未经治疗的根通道和周周病变的患病率.
- 为了研究未经处理的通道,周周病变和冠状封印之间的联系.
- 使用圆束计算断层扫描 (CBCT) 进行准确的3D评估.
主要方法:
- 采用了横截面研究设计.
- 分析了772个经过内牙治疗的牙的CBCT图像.
- 评估包括识别错过的通道和评估三维的周周病变,以及冠状状况.
主要成果:
- 观察到高患病率的周周病变 (29.4%) 和错过的根通道 (13.3%).
- 89.4%的牙表现出适当的冠状密封.
- 未经处理的道最常见的是上第一牙和下侧切口. 周病变最常见的是下侧切口和大第二牙.
结论:
- 在经过内牙治疗的牙中,缺失的根通道和相关的牙周病变的患病率很高.

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

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...
