As diagnostic imaging in dentistry becomes more complex, we find ourselves more involved in the treatment planning and diagnostic process than ever before. Our training essentially focuses on multi-modality diagnosis, so that we can be the go-to specialty for any diagnostic imaging test or interpretation.
At present, cone beam CT scanners are in vogue and will dominate the imaging landscape for the foreseeable future. However, oral radiologists also receive interpretive training in a broad range of more esoteric imaging such as MRI and nuclear medicine in order to be prepared for whatever the future brings us.
There are two paths to follow in oral radiology, but both intertwine, and it's not really possible to exclusively go down one or the other, because private practitioners of oral radiology regularly give CE presentations and academic radiologists are often affiliated with hospitals or private practices.
If you are interested in finding out more about the specialty, the best way to do it is to visit a CAOMR member's office and to talk to the staff and students at the University of Toronto. That way, you'll get a clearer sense of what a day's work entails, and whether it's something you're interested in pursuing.
