The evaluation of effect of developer age in the detection of approximal caries using three speed dental x-ray films: an in-vitro study.

Background And Objectives: Ever since the first radiograph was taken in 1895, radiographs have become an essential part of dental practice. Since radiation exposure for the patients is a major concern, it is important for us to reduce the radiation exposure to the patient and surrounding environment, without compromising the quality of image. Since improper film processing is one of the major causes of poor image quality, it is very important to test dental films under a variety of processing conditions.
