Bitewing radiography is a valuable technique for assessment of proximal caries, alveolar crest and periodontal status. Technical errors during radiography result in erroneous radiographic interpretation, misdiagnosis, possible mistreatment or unnecessary exposure of patient for taking a repeat radiograph.
In this study, we aimed to evaluate the efficacy of a film holder modified from the conventional one and compared it with that of conventional film holder.
Our study population comprised of 70 patients who were referred to the Radiology Department for bilateral premolar bitewing radiographs as requested by their attending clinician. Bitewing radiographs in each patient were taken using the newly designed holder in one side and the conventional holder in the other side. The acceptability of the two holders from the perspectives of the technician and patients was determined using a 0-20 point scale. The frequency of overlap and film positioning errors was calculated for each method.
The conventional holder had greater acceptability among patients compared to the newly designed holder (mean score of 16.59 versus 13.37). From the technicians' point of view, the newly designed holder was superior to the conventional holder (mean score of 17.33 versus 16.44). The frequency of overlap was lower using the newly designed holder (p<0.001) and it allowed more accurate film positioning (p=0.005).
The newly designed holder may facilitate the process of radiography for technicians and may be associated with less frequency of radiographic errors compared to the conventional holder.
咬合翼片X线摄影术是评估邻面龋、牙槽嵴和牙周状况的一项重要技术。X线摄影过程中的技术失误会导致错误的影像学解读、误诊、可能的误治或患者因需重复拍摄X线片而遭受不必要的辐射。
在本研究中，我们旨在评估一种对传统胶片夹进行改良后的胶片夹的效果，并将其与传统胶片夹进行比较。
我们的研究对象包括70例患者，这些患者应主治医生要求被转介至放射科进行双侧前磨牙咬合翼片X线摄影。每位患者的咬合翼片X线片，一侧使用新设计的胶片夹拍摄，另一侧使用传统胶片夹拍摄。使用0至20分的评分量表从技术人员和患者的角度确定两种胶片夹的可接受性。计算每种方法的重叠和胶片定位错误的频率。
与新设计的胶片夹相比，传统胶片夹在患者中具有更高的可接受性（平均得分分别为16.59分和13.37分）。从技术人员的角度来看，新设计的胶片夹优于传统胶片夹（平均得分分别为17.33分和16.44分）。使用新设计的胶片夹时重叠频率较低（p<0.001），并且它能使胶片定位更准确（p=0.005）。
与传统胶片夹相比，新设计的胶片夹可能会方便技术人员进行X线摄影过程，并且可能与更低的X线摄影错误频率相关。
