概括
超声波是一种可靠的,无辐射的工具,用于测量青少年正牙患者的膜骨水平 (ABL),比形束计算断层扫描 (CBCT) 更准确. 这种非侵入性方法有可能提高诊断能力.
科学领域:
- 矯正牙科 矯正牙科是一種矯正牙科.
- 放射学 放射学是一门学科.
- 医疗成像医学成像
背景情况:
- 圆束计算断层扫描 (CBCT) 是正牙诊断的标准,但涉及高剂量的辐射.
- 超声波为成像提供了一个非侵入性,无辐射的替代方案.
研究的目的:
- 评估超声波的可靠性,以测量膜骨水平 (ABL).
- 为了比较青少年正牙患者ABL的超声波测量与CBCT.
- 为了评估两种成像方式的内部和内部评分器可靠性.
主要方法:
- 从30名青少年患者中扫描了118个切口,使用CBCT (0.3毫米的口腔尺寸) 和超声波 (20 MHz).
- 气膜骨水平 (ABL),从水泥结 (CEJ) 到气膜骨峰 (ABC) 的距离,被测量了两次.
- 四位评级者进行了测量,以比较评级者内部和评级者之间的可靠性.
主要成果:
- 超声波和CBCT对ABL的平均差异 (MD) 是-0.07毫米 (95%的LoA: -0.47到0.32毫米).
- 部ABLMD为-0.18毫米 (95%的LoA: -0.53至0.18毫米);大ABLMD为0.03毫米 (95%的LoA: -0.28至0.35毫米).
- 超声波显示,相对于CBCT (intra-rater ICC=0.56-0.78; inter-rater ICC=0.69) 的超级可靠性,超声波显示了较高的内部 (ICC=0.83-0.90) 和内部 (ICC=0.97) 的可靠性.
结论:
- 在青少年正牙科中,CBCT可能缺乏评估下切口ABL的可靠性.
- 超声波成像是一种有希望的,无辐射的,具有成本效益的,便携式的工具,用于青少年的ABL评估.

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...
