==Tooth Resorption in Cats==

Radiographs of affected teeth often show root resorption that is far more advanced than expected. Every [[:Category:Tooth - Anatomy & Physiology|tooth]] with a clinical [[Dental Chart Notation|TR]] should be radiographically evaluated, not only to determine severity but also to determine the type of root changes that are occurring and to identify concurrent pathology. Multiple teeth are often involved in affected individuals. Therefore, full [[Intra-Oral Radiography|mouth radiographs]] of all teeth may be indicated when a patient is diagnosed with TR. Some practitioners recommend full mouth radiographs of all feline patients to identify pathology that is not clinically apparent.<br><br>

Radiographic evaluation allows both the type and stage of a lesion to be determined, both of which can be easily recorded on the patient’s [[Dental Recording|dental chart]].

==Tooth Resorption in Dogs==

Similar to cats and other species, dogs are affected by TRs from both known causes (most commonly [[Periodontal Disease|periodontal]] or endodontic infection or inflammation) and from unproved etiology. The (currently) idiopathic TRs are far less prevalent than the feline lesions and appear very similar to the idiopathic type of TRs in cats. Type 1, type 2, and combined TRs are found in dogs, and they can be staged using the same criteria that are used to stage feline TRs.
