概括

与ProTaper Universal SX,OneFlare和HyFlex EDM仪器相比,Gates Glidden钻孔在冠状炎炎过程中引起了更多的根牙裂. 新的旋转仪表显示裂纹发生率降低.

科学领域:

牙周内科医院牙周内科医院牙周内科医院
牙科材料科学牙科材料科学
恢复性牙科恢复性牙科

背景情况:

冠状炎燃烧是根运河准备的关键一步.
牙根裂的发生率可能会受到使用的旋转仪器类型的影响.
了解仪器诱导的裂形成对于内牙治疗成功至关重要.

研究的目的:

用不同的旋转仪器评估和比较在冠状炎燃烧后根牙裂纹形成的速度.
评估与特定仪器相关的阳性损伤的可能性.

主要方法:

使用了70个提取的前牙,其中只有一个根通道.
牙被随机分配到五组 (n=14):一个对照组和四个实验组.
实验小组使用Gates Glidden钻头,ProTaper Universal SX,OneFlare或HyFlex EDM仪器进行了冠状燃烧.

主要成果:

盖茨·格莱登 (Gates Glidden) 钻探表明,牙根牙裂的发病率在统计学上显著上升 (P < 0.05).
在ProTaper Universal SX,OneFlare和HyFlex EDM仪器中,裂纹形成率较低 (P > 0.05).
在盖茨格莱登钻机与其他测试的旋转仪器之间观察到裂纹发生率的显著差异.

结论:

盖茨·格莱登钻具的使用与冠状炎燃烧期间根牙裂形成的增加有关.
似乎ProTaper Universal SX,OneFlare和HyFlex EDM是更安全的替代品,导致的裂较少.
临床医生在选择冠状炎手术仪器时,应考虑裂纹诱导的可能性.

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...
