摘要

背景/目的:本研究的目的是评估两种具有CMOS和PSP传感器的通用图像受体在四种不同曝光时间下对图像质量评分(IQS)、倦怠发生率(BI)和宫颈宽度(CW)的诊断准确性。材料与方法:对15个石蜡块模型中的43颗切牙进行4次不同曝光时间的CMOS组和PSP组曝光,共获得120张图像。所有图像由3名牙颌面放射科医生根据3种不同标准进行评估;智商,智商,智商。结果:组间诊断质量评分差异有统计学意义(0,1);0,125和0,16 SEC曝光时间。PSP组表现出更高的智商。暴露时间为0.125秒和0.16秒时,PSP组表现出较高的BI百分比。PSP组平均CW值较低。尽管CMOS组的平均连续曝光时间与暴露时间没有统计学上的显著差异;PSP组暴露时间差异显著。我们可以说,PSP系统显示出更高的图像质量,因此曝光时间可以减少,唉,同样的结论是不可能与CMOS系统使用。结论:与CMOS系统相比,我们使用的PSP系统具有更高的图像质量感知。随着曝光时间的增加,PSP系统表现出更多的燃尽效应,而CMOS系统则保持不变。

Evaluation of Two Dental Digital Imaging Systems Based on Quality Scorings, Burn-Out Effects and Cervical Width Determination
Summary Background/Aim: The aim of the present study is to evaluate diagnostic accuracy of two generic image receptors with CMOS and PSP sensors for image quality scoring (IQS), burnout incidences (BI) and cervical widths (CW) with regard to four different exposure times. Material and Methods: 43 incisor teeth within 15 paraffin block models were exposed at 4 different exposure times both for the CMOS and PSP groups, and a total number of 120 images were obtained. All images were evaluated by 3 dentomaxillofacial radiologists via 3 different criteria; IQS, BI, CW. Results: Diagnostic quality scorings between groups displayed statistically significant difference for 0,1; 0,125 and 0,16 sec exposure times. PSP group revealed higher IQS. For 0,125 and 0,16 seconds exposure times, PSP group showed higher percentages of BI. Average CW were lower in PSP group. Although no statistically significant difference was found between average CW vs. exposure times in the CMOS group; PSP group revealed significant differences among exposure times. We can state that, the PSP system displayed higher image quality so exposure times can be reduced, alas, the same conclusion is not possible with CMOS system used. Conclusions: Image quality perception is higher in PSP system we used, compared with CMOS system. PSP system display more burnout effects with increasing exposure times, while CMOS system is constant.
