Tag Archives: crown amputation
This is the same cat as seen in the previous post. Tooth 307 has both type I (mesial root) and type II tooth resorption. The distal root is replaced by bone and there are no endodontic changes. Therefore crown amputation is possible. The mesial root however is surrounded by a distinct periodontal ligament space and must be extracted.
This cat has type II tooth resorption with severe proliferation of a portion of the crown on the right canine tooth. The cusp was lost when the technician bumped the tooth during induction. Crown amputation and intentional root retention can only be done in cases like this were the tooth root bears no surrounding periodontal ligament, there is no endodontic disease and the root is being replaced by bone grossly and radiographically.
