Some orthodontists may be exposing young patients to unnecessary radiation when they order 3-D X-ray imaging for simple orthodontic cases before considering traditional 2-D imaging, suggests a paper published by University of Michigan faculty.
There is ongoing debate in the orthodontic community over if and when to use cone beam computed tomography (CBCT) for orthodontic diagnosis and treatment planning, said Dr. Sunil Kapila, lead author of the paper
“There is nothing published on current usage patterns,” Kapila said. “Most of the information is anecdotal. Some clinicians and orthodontists are using this technology routinely, but I believe that most of those that use 3-D imaging use it fairly judiciously,” Kapila said.
