The aim was to compare patient discomfort and evaluate the frequency of retakes using intraoral digital receptors and conventional film for radiographic examination of mandibular third molars.
Both mandibular third molar regions were examined in 110 patients with 2 of 5 digital intraoral receptors. Discomfort was scored on a visual analog scale (VAS) for each receptor and for film as a reference. If the whole tooth was not imaged on the digital image, a retake was performed using film. t Tests evaluated differences in VAS score, chi-squared tests evaluated differences in frequency of remakes, and logistic regression analyses evaluated factors predisposing for retake.
No significant difference existed in VAS scores between right and left sides for film (P = .24). The digital receptors were more uncomfortable than film (P < .001), and CDR-APS was more uncomfortable than Digora (P = .049) and Vista (P = .002). The frequency of retakes was higher for solid-state sensors than photostimulable phosphor plates (PSPs) (P < .018). Gender (P = .022), type of receptor (P < .021), and VAS score (P = .001) were predisposing factors for a retake.
Patients accepted film better than digital intraoral receptors, and retake frequency was lower for PSPs compared with solid-state sensors.
比较患者的不适感，并评估使用口腔内数字感受器和传统胶片对下颌第三磨牙进行放射检查时的重拍频率。
对110名患者的双侧下颌第三磨牙区域使用5种数字口腔内感受器中的2种进行检查。以视觉模拟量表（VAS）对每个感受器及作为对照的胶片的不适感进行评分。如果数字图像上未完整显示牙齿，则使用胶片重新拍摄。t检验评估VAS评分的差异，卡方检验评估重拍频率的差异，逻辑回归分析评估重拍的易感因素。
胶片左右两侧的VAS评分无显著差异（P = 0.24）。数字感受器比胶片更让人不适（P < 0.001），CDR - APS比Digora（P = 0.049）和Vista（P = 0.002）更让人不适。固态传感器的重拍频率高于光激励荧光板（PSP）（P < 0.018）。性别（P = 0.022）、感受器类型（P < 0.021）和VAS评分（P = 0.001）是重拍的易感因素。
患者对胶片的接受度优于口腔内数字感受器，与固态传感器相比，PSP的重拍频率更低。
