Understand legal issues when using CBCT scans
by Stuart J. Oberman, USA
Dentists are legally and ethically obligated to do no harm to their patients. Improper diagnosis after using a CBCT (cone-beam computed tomography) does not align with this standard because delay of diagnosis leads to delay of treatment. This is not in the best interest of the patient because it can lead to an inferior prognosis. Also, not every patient requires a CBCT scan; therefore, it is the dentist’s responsibility to determine whether a CBCT scan is necessary by using reasonable, careful judgment in light of the patient’s medical and dental history and thorough examination. The dentist should do a cost-benefit analysis before requesting a CBCT scan. When doing so, the dentist should consider whether the likely benefit to the patient exceeds the ionizing radiation risk and the financial cost.
Dentists’ scope of legal responsibility to diagnose
When using CBCT, as with other diagnostic tools, the
dentist’s responsibility is not limited to the area of interest being
diagnosed or treated. The treating dentist is legally responsible
for diagnosing any disease that falls within the scope of the
dentist’s license, which is normally broad in scope,
encompassing all diseases and lesions of the jaw and related
structures. As for a dentist’s responsibility for diagnosing a
disease that falls outside the scope of the dentist’s license, the
answer is not clear. Thus, it is always a good idea to be cautious
and assume the responsibility to recognize any abnormality that
appears anywhere on the CBCT scan. If ... ART 1 ... dentist is
unsure of ...ART 2... scan results, he or she should consult with
...ART 3... specialists in the field or refer ...ART 4... patient to ...ART 5... specialist.
