The aim of this cross-sectional study was to explore the eye tracking (ET) performance of postgraduate pediatric dental students in correctly detecting abnormalities in different sets of panoramic radiographs. This observational study recruited postgraduate pediatric dental students to evaluate seven panoramic radiographs. RED-m SMI software (Sensomotoric Instruments, Teltow, Germany) was used to track the participants' eye movements as they looked at the radiographs. The data collected for areas of interest (AOIs) included revisit counts, fixation counts, fixation times, entry times, and dwell times. Univariate and bivariate analyses were conducted to summarize the participants' characteristics and ET measures. The overall percentage of correctly located AOIs was 71.7%. The residents had significantly more revisits and fixation counts in AOIs located in one sextant than in multiple sextants ( < 0.001). Similar patterns were observed for fixation and dwell times ( < 0.001), but not for entry time. Heatmaps showed that the highest density of fixations was on the AOIs and the residents fixated more on dentition than on bony structures. In single-sextant radiographs, residents had significantly more revisits and fixation counts for AOIs compared to those of multiple sextants. Residents had slower entry times and dwelled less on AOIs located in multiple sextant(s). The reported findings can direct dental educators to develop a standardized scan scheme of panoramic radiographs to minimize misdiagnosis.
这项横断面研究的目的是探讨儿科牙科研究生在正确检测不同组全景X光片异常方面的眼动追踪（ET）表现。这项观察性研究招募了儿科牙科研究生来评估七张全景X光片。在参与者观看X光片时，使用RED-m SMI软件（德国特尔托夫的Sensomotoric Instruments公司）来追踪他们的眼动。收集的感兴趣区域（AOI）的数据包括复查次数、注视次数、注视时间、进入时间和停留时间。进行了单变量和双变量分析以总结参与者的特征和ET测量结果。正确定位的AOI的总体百分比为71.7%。住院医师在位于一个象限的AOI中的复查和注视次数明显多于位于多个象限的AOI（<0.001）。在注视时间和停留时间方面也观察到了类似的模式（<0.001），但进入时间没有。热图显示，注视的最高密度在AOI上，住院医师对牙列的注视比对骨结构的注视更多。在单象限X光片中，住院医师对AOI的复查和注视次数明显多于多象限X光片。住院医师进入位于多个象限的AOI的时间较慢，并且在这些AOI上停留的时间较少。报告的研究结果可以指导牙科教育工作者制定全景X光片的标准化扫描方案，以尽量减少误诊。
