Abstract

OBJECTIVE

To compare and analyze the precision, accuracy, and reliability of commonly used cone-beam computed tomography (CBCT) software in predicting the mesiodistal diameter of impacted canines.

METHODS

This study was conducted on 11 patients (six males and five females, mean age: 17.5±5.5 years) with either unilateral or bilateral impacted canines in the maxilla or mandible. DICOM data sets of the patients obtained from CBCT scans were then loaded and visualized with four selected CBCT software to measure the widest mesiodistal diameter of the impacted teeth. Physical measurements using a digital vernier caliper, kept as a control, were also made on the extracted teeth and orthodontically erupted teeth. The collected data underwent statistical analysis, and the statistical significance level was set at p<0.05.

RESULTS

The Bland-Altman analysis was performed to quantify the agreement between different software to the digital caliper, showing a narrow difference for all plots. Kruskal-Wallis ANOVA test followed by a post hoc test was performed to determine whether there was any difference in measuring the mesiodistal diameter of the impacted canine among the five methods, and tend no statistically significant difference was found among the five methods. Intraclass correlation (ICC) was performed, and measurements made with all CBCT software yielded an ICC greater than 0.95, indicating high reliability of the selected software.

CONCLUSION

All the evaluated CBCT imaging software exhibited a high degree of reliability, and accuracy in precise measurement of the mesiodistal diameter of an impacted tooth.

摘要

目的

比较并分析常用锥形束计算机断层扫描（CBCT）软件在预测埋伏尖牙近远中径方面的精度、准确性和可靠性。

方法

本研究对11例上颌或下颌单侧或双侧埋伏尖牙患者（6例男性，5例女性，平均年龄：17.5±5.5岁）进行。从CBCT扫描获得的患者DICOM数据集，然后用四种选定的CBCT软件加载并可视化，以测量埋伏牙的最宽近远中径。还对拔除的牙齿和正畸萌出的牙齿使用数字游标卡尺进行物理测量作为对照。对收集的数据进行统计分析，统计显著性水平设定为p<0.05。

结果

进行Bland-Altman分析以量化不同软件与数字卡尺之间的一致性，所有图显示差异较小。进行Kruskal-Wallis方差分析，随后进行事后检验，以确定五种方法在测量埋伏尖牙近远中径方面是否存在差异，五种方法之间未发现统计学上的显著差异。进行组内相关系数（ICC）分析，所有CBCT软件的测量结果ICC均大于0.95，表明所选软件具有高可靠性。

结论

所有评估的CBCT成像软件在精确测量埋伏牙近远中径方面均表现出高度的可靠性和准确性。
