Ionizing radiations have a biologic damage effect either somatic or genetic effects on the living system and poor radiographic
detection of early proximal caries. In addition to, digital systems are characterized by their flexibility: the acquisition dose
can be reduced at the expense of image quality and vice versa. The imaging parameters must be optimised according to the best
performance of a particular system. Digital techniques increasingly offer options for dose reduction. At the same time, there is a
risk of substantially increasing the patient dose, possibly unawares, due to the lack of visual control. Therefore, implementation
of dose indicators and dose monitoring is mandatory for digital radiography. Moreover, proper selection of exposure parameters
to avoid re-exposure to patients due to poor image quality. In addition to, identifying and survey parameters that allow the
detection of artificial lesions or the semi-quantitative assessment of subjective image impression, as a surrogate for image
quality and relate these parameters to a reference of dose. Then, determined accuracy of CCD systems in early detection of
proximal caries in regard to the required radiation dose.
