Root canal therapy, dog

    Root canal therapy of the left maxillary canine tooth of a dog. This image depicts the radiographic appearance of root canal therapy. During root canal therapy, the pulp is removed, and the canal is antiseptically treated, dried, and obturated. A radiopaque restoration is then placed to seal the canal from the external environment.
