Radiology has become very sophisticated and expensive. This is why the most performing    x-ray machines are found in the centers for radiology.
These exams are usually necessary for surgery and implantology. This is the domain for the specialist in radiology who has studied both medicine and dentistry.
Progress of the films as well as of captors have made it possible to considerably reduce the exposure dose.

The legal directives concerning radioprotection of patients and staff are under the responsibility of theDFSP (Département Féderal de Santé Publique) who also organizes the training of staff and periodic controls of radiographic equipment. The dosage measurements are done monthly.
