This cat presented with bilateral type II tooth resorption associate with the third mandibular premolars. No periodontal ligament space is discernable. If a distinct space was present or if there were indications that the tooth was nonvital as indicated by a periapical lucency then extraction is indicated. In this case crown amputation and intentional root retention is possible.
No periodontal ligament space is present surrounding the 3rd premolar
The gingiva has proliferated into the crown defect and is painful.
A periosteal elevator is used to expose the tooth and marginal bone and provide space to place the bur without damaging the gingiva.
The bur is angled to allow the air/water spray to splay the gingival margin and expose the bone.
A postop radiograph confirms the marginal bone is smooth.
The defect is sutured using 5-0 monocryl.
Great, the images made the concept very clear
As this is one of the sentinel teeth for resorptive lesions in cats and there appears to be some gingival recession and bone loss around tooth 409, did you perform a full mouth radiographic survey on this individual? What dental homecare did you recommend for this cat? As ever, pictures are beautiful and great to see your approach to these cases. Best wishes, David
Hello David,
We perform full mouth radiography on all cases. Home care recommendations are always the same with brushing, healthy mouth, oravet etc. Compliance is almost always nil.

Great post..the images are clear ..Many gross lesions are small and not readily detectable by awake oral examination alone. Magnification, immobilization and lighting generally provide a thorough gross evaluation but will not uncover tooth resorption below the level of the marginal bone. Therefore, dental radiography is paramount in establishing an adequate diagnosis.
