Perhaps the most common reason for extraction of feline teeth is due to the presence of a resorptive lesion. RL’s may be identified as either a type 1 (roots remain relatively unaffected by the resorption) or type 2 (replacement resorption of the roots with loss of the periodontal ligament, dentinal structure and root canal system of the root and replacement with bone). The type of the resorptive lesion can only be identified radiographically. It is important to know what type of lesion is affecting the tooth as the treatment options vary.

This technique is used when a tooth is undergoing resorption and there is no normal root structure remaining. This technique can only be used after a diagnosis of type 2 resorptive lesions has been made radiographically.

#Take a dental radiograph to confirm that the resorptive lesion is a type 2.

#Raise a small mucoperiosteal flap –use a no.11 scalpel blade to make the releasing incisions then a periosteal elevator to raise the flap.

#Use a small round bur to remove the crown of the tooth, sectioning the tooth just below the level of the alveolar bone, taking care not to damage the soft tissue on the lingual/palatal aspect of the tooth.

During the anaesthetic and immediately after the dental procedure the temperature of the pet should be monitored closely and warmth provided if needed as hypothermia is a major concern during extensive dental procedures. Good analgesia should be administered throughout and antibiotic cover should be given at the veterinary surgeons discretion.
