Incisor lesions: equine odontoclastic tooth resorption and hypercementosis

摘要

A painful and destructive dental disease, preferentially affecting incisors, has been increasingly recognised in aged horses during the last years. Oral examination reveals incisor mobility or displacement, oral pain, gingival swelling and gingivitiswhich are occasionally associated with ulcerations and draining tracks with purulent discharge. Radiographs show substantial changes to the intra-alveolar aspects of the teeth and their surroundings, i.e. the periodontal space and alveolar bone. Althoughthe radiographic appearance of the diseased teeth is not identical in all patients, there are 2 prominent radiographic findings which often occur in combination.
