Abstract
The position of the condyle can be determined using different diagnostic tools, among which are transcranial X-rays (RT), Cone Beam Computed Tomography (CBCT), and the Condylar Position Indicator (CPI). This study aimed to determine the concordance among the CPI, the CBCT, and the RT as diagnostic methods for determining the condyle position. Materials and method: 32 valid cases, each of which had an RT, a CBCT, and a CPI, were analyzed by three observers. SPSS V. 26.0 program was used to calculate the Kappa trust interval, using the jackknife technique which allows to estimate of the standard error between observers. To evaluate the condylar position using CPI, an AD2 articulator was employed. A Pullinger and Hollender layout was used in the tomographic and transcranial images. Results: The concordance among the three observers for each method resulted in a value of Kappa higher than 0.879. The concordance between CBCT and RT was 0.0627, between CPI and RT it was 0.247, and between CBCT and CPI it was .188. Conclusion: The level of concordance obtained between the three observers with any given diagnostic method was very good, which indicates that the concordance that each observer obtained regarding each diagnostic method is trustworthy. In this study, it is concluded that there is a concordance in the diagnosis regarding the position of the condyle of the tomography with the transcranial radiography. There is no concordance between tomography and CPI. There was also no concordance between the CPI and the transcranial radiography.
髁突的位置可以通过不同的诊断工具来确定,其中包括经颅x射线(RT),锥束计算机断层扫描(CBCT)和髁突位置指示器(CPI)。本研究旨在确定CPI、CBCT和RT作为确定髁突位置的诊断方法之间的一致性。材料和方法:32例有效病例,每例均有RT、CBCT和CPI,由3名观察员分析。使用SPSS V. 26.0程序计算Kappa信任区间,使用可估计观察者之间标准误差的叠刀技术。为了使用CPI评估髁突位置,使用AD2关节器。层析成像和经颅成像采用Pullinger和Hollender布局。结果:三名观测者对各方法的一致性Kappa值均大于0.879。CBCT与RT的一致性为0.0627,CPI与RT的一致性为0.247,CBCT与CPI的一致性为0.188。结论:三名观察者对任何一种诊断方法的一致性都很好,说明每名观察者对每一种诊断方法的一致性都是可信的。本研究认为,经颅x线摄影对髁突位置的诊断是一致的。层析成像与CPI之间没有一致性。CPI与经颅x线摄影也不一致。
