The rаdiаtiоn expоsure fоr digitаl imaging systems is 50% to 60% less than that required for film used in conventional radiography. The aluminum filters in the tubehead help to protect patients from excessive radiation exposure by removing the high energy photons from the primary beam.
Periоdоntаl diseаse diаgnоsis requires both a radiographic and clinical examination. Incipient occlusal caries diagnosis requires a radiographic exam.
