To compare the accuracy of determining the distance between alveolar crest and cementoenamel junction (CEJ) in digital radiography with two image processing software programs.
In this in vitro study, 63 sites in a dried human mandible underwent digital periapical radiography. The distance from the alveolar crest to the CEJ was calculated using DentalEye and Scanora software programs and compared with the standard mode (measured on the skull). Statistical analysis was performed with analysis of variance (ANOVA) and paired t-test using Statistical Package for the Social Sciences (SPSS) 23 at α = 0.05.
There were significant differences in the distances between CEJ and the alveolar crest at the mesial surfaces as measured by the three techniques in standard mode, using DentalEye and Scanora (p-value ≤ 0.03) softwares; however, there were no significant differences between the results on distal surfaces (p-value = 0.248).
Under the limitations of the present study, the measurements made to determine the distance from the CEJ to the alveolar crest with DentalEye and Scanora, relative to each other, and relative to the standard mode, were accurate only on distal surfaces of teeth.
Digital dental software programs are useful assets that can enhance the diagnosing ability and reduce the need of taking extra images.
比较使用两种图像处理软件程序在数字放射摄影中测定牙槽嵴与牙骨质釉质界(CEJ)之间距离的准确性。
在这项体外研究中,对一具干燥人下颌骨的63个部位进行了数字化根尖片摄影。使用DentalEye和Scanora软件程序计算从牙槽嵴到CEJ的距离,并与标准模式(在颅骨上测量)进行比较。使用社会科学统计软件包(SPSS)23进行方差分析(ANOVA)和配对t检验,α = 0.05。
在标准模式下,使用DentalEye和Scanora软件,三种技术测量的CEJ与牙槽嵴在近中面的距离存在显著差异(p值≤0.03);然而,远中面的测量结果之间无显著差异(p值 = 0.248)。
在本研究的局限性下,使用DentalEye和Scanora测定从CEJ到牙槽嵴的距离,相对于彼此以及相对于标准模式,仅在牙齿远中面是准确的。
数字牙科软件程序是有用的工具,可提高诊断能力并减少额外影像拍摄的需求。
