概括

与直接视觉相比,牙科操作显微镜 (DOM) 显著改善了下第一个前的根通道孔的检测. 微型CT成像揭示了复杂的根管解剖学,但在临床上并不适用.

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
诊断成像诊断成像诊断成像

背景情况:

带有深层根槽的下第一个前带来了诊断挑战.
精确识别根管形态对于成功的内牙治疗至关重要.

研究的目的:

评估诊断方法 (直接视觉,牙科操作显微镜,2D放射) 检测沟孔和配置在下第一个前与深根槽.
将这些临床方法与微型计算机断层扫描 (micro-CT) 进行比较.
评估艾哈迈德等人研究的适用性. (2017) 分类系统.

主要方法:

使用微型CT扫描了133个下第一个前,其中有深深的根槽.
检查人员使用直接视觉 (DV) 和牙科操作显微镜 (DOM) 评估了道孔.
根运河配置通过探索,二维放射图和微型CT数据进行了评估.

主要成果:

除了三个牙外,所有牙都表现出多个道,其中1MFP1-2是最常见的配置 (19.54%).
与DV相比,DOM显著改善了与DV相比的通道孔的检测 (p < 0.001).
微型CT显示了比放射学方法更复杂的配置 (p < 0.001).

结论:

带有深的下第一个前具有复杂和可变的根管系统.
DOM增强了通道孔的检测,提高了诊断的准确性.
微CT对于理解根管形态和开发临床诊断策略至关重要.

Tooth Anatomy

Tooth Anatomy

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...
