In order to determine the influence of different processing solutions on the quality of the radiograph, an aluminum step-wedge was radiographed with three speed D periapical films of three different manufacturers. The films were developed in five different processing solutions at standardized conditions, according to the manufacturers' instructions. Data concerning film density, contrast, fog plus base, and relative speed of each film-solution combination were compiled in an attempt to evaluate the optimal film-solution combination.
为了确定不同冲洗液对根尖片质量的影响，用三种不同厂家的D速根尖片对铝梯级楔形块进行了X线摄影。根据厂家说明，在标准化条件下，用五种不同的冲洗液冲洗这些胶片。汇总了每种胶片 - 冲洗液组合的胶片密度、对比度、灰雾加片基密度以及相对感光度的数据，以评估最佳的胶片 - 冲洗液组合。
