To compare the standards of periapical radiography with a CCD-image receptor with film.
Three radiography technicians exposed a total of fifty teeth from all areas of the jaws using either size 1 or size 2 film and the Sidexis (Siemens, Bensheim, Germany) direct digital dental radiography system with the appropriate film holders. Image quality was assessed by two dental radiologists for nine individual criteria and overall, on a three-point scale.
There was a significant difference between film and sensor exposures (P < 0.014). Six per cent of dental films required retakes compared with 28% with the sensor.
Periapical radiography with a CCD sensor leads to more errors and thus more retakes than conventional film.
比较使用电荷耦合器件（CCD）图像接收器的根尖片与胶片的标准。
三名放射技师使用1号或2号胶片以及配备适当胶片夹的Sidexis（德国本斯海姆西门子公司）直接数字化牙科放射成像系统，从颌骨的各个区域总共拍摄了50颗牙齿。两名牙科放射科医生根据九个单独标准和总体情况，采用三分制对图像质量进行评估。
胶片和传感器曝光之间存在显著差异（P < 0.014）。6%的牙科胶片需要重新拍摄，而传感器的这一比例为28%。
与传统胶片相比，使用CCD传感器进行根尖片拍摄会导致更多错误，因此需要更多重新拍摄。
