Off with the crown?
Mar 01, 2007
Editors Note: In a new series, DVM Newsmagazine asks experts within a variety of veterinary specialties to bust commonly held medical, business or professional myths. This month, we bite into dentistry.
Myth: Crown amputation is the new treatment of choice for feline odontoclastic resorptive lesions (FORL or RL) in cats.
REALITY: Crown amputation with intentional root retention for feline teeth with RL is an acceptable alternative to complete extraction of the entire tooth in select cases that meet specific criteria.There appear to be two distinct types of RL. Type I lesions are inflammatory in nature and arise at the neck region of the tooth. (Figure 1) The periodontal ligament surrounding the teeth of these Type I lesions is generally intact and the gingiva is inflamed and likely painful.
These teeth are not candidates for crown amputation and intentional root retention. The entire tooth and root must be removed.
