概括
这项研究将儿科旋转文件与ProTaper系统进行了比较,该系统用于使用圆束计算断层扫描 (CBCT) 清洁初级牙通道. ProTaper去除了更多的牙,但儿科病例档案之间的差异并不显著.
科学领域:
- 牙周内科医院 牙周内科医院 牙周内科医院
- 儿科牙科 儿科牙科
- 牙科材料科学 牙科材料科学
背景情况:
- 有效地清理母牙根管对于成功的内牙治疗至关重要.
- 儿科旋转文件系统旨在提高在准备小根管道的效率和有效性.
- 圆束计算断层扫描 (CBCT) 提供了一种精确的方法来评估根运河准备和体积变化.
研究的目的:
- 为了比较三种儿科旋转文件 (Pro AF Baby Gold,Kedo SG Blue,Prime Pedo) 与初级牙中标准的ProTaper成人文件系统的清洁效果.
- 为了评估使用CBCT的不同旋转文件系统准备的根通道的体积变化.
主要方法:
- 提取的四十个落叶的第二牙被随机分配到四个组 (每组n=10):Pro AF Baby Gold,Kedo SG Blue,Prime Pedo和ProTaper.
- 用分配的旋转文件系统进行了根运河准备.
- 获得了手术前和手术后的CBCT扫描,以分析根通道的体积变化.
- 统计分析包括配对的t测试和ANOVA与Tukey hoc后期测试.
主要成果:
- 在两组之间观察到平均体积变化的统计学上显著差异 (ANOVA,p=0.002).
- 与Pro AF Baby Gold (p=0.033) 和Prime Pedo (p=0.008) 相比,ProTaper系统在牙去除方面显示出统计学上显著的差异.
- 在三种儿科旋转档案系统中,没有发现体积变化的统计学上显著差异.
结论:
- 在ProTaper成人文件系统删除了更多的牙比评估的儿科旋转文件,虽然没有显著超过Kedo SG蓝色.
- 在儿科系统中,Kedo SG Blue显示出比Pro AF Baby Gold和Prime Pedo更大的牙去除趋势,但这在统计学上并不显著.

Computed Tomography

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...
