Combined Type I and Type II Tooth Resorption in a Cat
by Brett on Jun.22, 2010, under Veterinary Dental Cases
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.
Type II Tooth Resorption in a Cat Canine Tooth
by Brett on Jun.15, 2010, under Veterinary Dental Cases
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.

This is the same patient from the prior post. This is an example of Type I tooth resorption on the mesial root and Type II resorption on the distal root.

This 3rd mandibular premolar has very subtle swelling of the gingiva distal to the crown
Radiographically you can see the periodontal ligament space on the mesial root classifying this as type I tooth resorption. This requires full root extraction. In the distal root the space is not present and bone is replacing the rooth. In this case crown reduction of more specifically here partial tooth extraction may be performed to remove tooth to the point where only bone is present. This requires extensive experience and a very high powered head surgical magnifyer to perform properly.

The right mandibular canine tooth in this cat doesn't appear diseased. A close look shows a slight amount of inflammation distal in the gingival just distal to the toothMucoperiosteal flap exposure with careful dissection with a blade and feline periosteal elevator reveals the crown and allows for crown reduction with a round carbide bur.Severe destruction of tooth and the lack of a peridontal ligament space and not evidence of endodontic disease make the canine a candidate for crown amputation.Severe destruction of tooth and the lack of a peridontal ligament space and not evidence of endodontic disease make the canine a candidate for crown amputation.
