摘要

目的:本研究的目的是使用一种涉及锥束计算机断层扫描(CBCT)的新方法客观地检测模拟牙齿强直。材料和方法:模拟单根恒牙的牙齿强直,并获得不同电流水平(5、6.3和8 mA)和体素大小(0.08、0.125和0.2)下的CBCT扫描。在轴向重建中,在21个强直性区域和21个非强直性区域的牙周韧带间隙上垂直放置一条兴趣线,并通过线形图将沿兴趣线的所有体素的CBCT灰度值与其对应的x坐标进行绘制以生成轮廓。图像对比度分别提高30%和60%,并重复进行轮廓评估。从所有图像中获得所得抛物线的内部面积,并在不同对比度增强条件、体素大小和mA水平下,使用多路方差分析和Tukey事后检验比较强直性和非强直性区域(α=0.05)。结果:所有非强直性区域的抛物线内面积均显著高于强直性区域(PPP>0.05)。结论:该方法对模拟牙强直的检测具有一定的适用性;增强的图像对比度导致更强的可检测性。

A novel method of objectively detecting tooth ankylosis using cone-beam computed tomography: A laboratory study.

Purpose: The aim of this study was to objectively detect simulated tooth ankylosis using a novel method involving cone-beam computed tomography (CBCT).

Materials and methods: Tooth ankylosis was simulated in single-rooted human permanent teeth, and CBCT scans were acquired at different current levels (5, 6.3, and 8 mA) and voxel sizes (0.08, 0.125, and 0.2). In axial reconstructions, a line of interest was perpendicularly placed over the periodontal ligament space of 21 ankylosed and 21 non-ankylosed regions, and the CBCT grey values of all voxels along the line of interest were plotted against their corresponding X-coordinates through a line graph to generate a profile. The image contrast was increased by 30% and 60% and the profile assessment was repeated. The internal area of the resulting parabolas was obtained from all images and compared between ankylosed and non-ankylosed regions under different contrast enhancement conditions, voxel sizes, and mA levels using multi-way analysis of variance with the Tukey post hoc test (α=0.05).

Results: The internal area of the parabolas of all non-ankylosed regions was significantly higher than that of the ankylosed regions (P<0.05). Contrast enhancement led to a significantly greater internal area of the parabolas of non-ankylosed regions (P<0.05). Overall, voxel size and mA did not significantly influence the internal area of the parabolas (P>0.05).

Conclusion: The proposed novel method revealed a relevant degree of applicability in the detection of simulated tooth ankylosis; increased image contrast led to greater detectability.
