概括
圆束计算断层扫描 (CBCT) 有效地可视化了上的第二个口道. 三维Veraview X800 F150P扫描仪,特别是80x40 FOV和0.125 voxel大小的3D扫描仪,在文物存在条件下表现出卓越的准确性和灵敏性.
科学领域:
- 牙周内科医院 牙周内科医院 牙周内科医院
- 牙科放射学 牙科放射学
- 圆光束计算机断层扫描 (CBCT)
背景情况:
- 在大牙中识别第二个大牙道存在临床挑战.
- 圆束计算断层扫描 (CBCT) 提供体积成像来帮助可视化.
- 这项研究评估了用于检测该通道的CBCT协议,特别是在图像文物中.
研究的目的:
- 确定不同CBCT协议和决议的有效性.
- 评估大牙中第二个大牙道的可视化.
- 在图像工件的存在下评估性能.
主要方法:
- 扫描了28个大牙,这些牙有准备好并堵塞的道 (不包括第二个大牙).
- 使用OP300 MAXIO (4个协议) 和3D Veraview X800 F150P (3个协议) 进行扫描.
- 五名盲人评估者评估了准确性,灵敏性和特异性;光显微镜证实了道存在.
主要成果:
- 三维Veraview X800 F150P显示出卓越的精度 (96%),灵敏度 (100%) 和特异性 (86%).
- 50x50/0.085协议产生了高灵敏度 (78%),特异性 (100%) 和精度 (82%).
- 两个扫描仪都可视化了通道,但Veraview X800 F150P的整体表现更好.
结论:
- 三维Veraview X800 F150P是有效的可视化第二个 mesiobuccal通道.
- 确定的最佳协议是80x40FOV,具有0.125个voxel的大小.
- 这种方案是推用于检测第二个 mesiobuccal通道,即使有文物.

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...
