To determine the performance of different processing solutions using an automatic processor for dental radiography.
One brand of dental X-ray film (Minimax, Chicago, IL, USA) was developed in an automatic processor using four different brands of processing solution: Megasan (MGS, Megasan, Ankara, Turkey), (HAC, Ankara, Turkey), Fuji (Fuji Medical, Hacettepe Cedex, France) and RP X-Omat (Eastman Kodak, Rochester, NY, USA) at a range of temperatures. Performance was evaluated with respect to base plug fog density, relative speed and contrast.
All solutions produced acceptable base plus fog values. MGS produced significantly greater densities (P < 0.05) than the other three solutions. Contrast obtained with Kodak and Fuji solutions was less than with MGS and HAC. Developing temperature recommended by the manufacturer of the processor were found to be higher than that needed to achieve a clinically acceptable film.
Depending on the processor and processing solutions used, exposure time and processing temperature can be modified while maintaining image quality. The cheapest processing solution (MGS) gave the same results as the more expensive.
使用牙科X线摄影自动冲洗机来测定不同冲洗液的性能。
使用一个品牌的牙科X线胶片（Minimax，美国伊利诺伊州芝加哥），在自动冲洗机中使用四种不同品牌的冲洗液进行显影：Megasan（MGS，土耳其安卡拉的Megasan公司）、（HAC，土耳其安卡拉）、富士（富士医疗，法国哈杰泰佩Cedex）和RP X-Omat（美国纽约罗切斯特的伊士曼柯达公司），在一系列温度下进行。从片基灰雾密度、相对感光度和对比度方面对性能进行评估。
所有冲洗液产生的片基加灰雾值均可接受。MGS产生的密度显著高于其他三种冲洗液（P < 0.05）。柯达和富士冲洗液获得的对比度低于MGS和HAC。发现冲洗机制造商推荐的显影温度高于获得临床可接受胶片所需的温度。
根据所使用的冲洗机和冲洗液，可以在保持图像质量的同时修改曝光时间和冲洗温度。最便宜的冲洗液（MGS）与更昂贵的冲洗液产生相同的结果。
