Ionizing radiations used in dental practice can cause biologic damage due to somatic or genetic effects on the living system
and reducing the dose delivered to the patient should always be a concern for the practitioner. Therefore, implementation of
dose indicators and dose monitoring is mandatory for dental radiography. Moreover, proper selection of exposure parameters
to avoid re-exposure to patients due to poor image quality should always be taken in consideration. The use of digital systems
in dentistry yielded the way for dose reduction and provided flexibility and ease of use, permitting the production of adequate
images optimized for each diagnostic task. Radiographic detection of early proximal caries is one of the most difficult tasks
in dental radiographic diagnosis; it is very technique-sensitive and needs adequate exposure parameters. Identifying and
surveying parameters that allow the detection of artificial lesions or the semi-quantitative assessment of subjective image
impression was done, as a surrogate for image quality and these parameters were related to a reference dose; then, accuracy of
CCD systems in early detection of proximal caries in regard to the required radiation dose was determined.
