How to obtain and interpret periodontal radiographs in dogs.
Oral radiography plays an important role in the diagnosis of periodontal disease. The diagnostic yield of radiographs is high, and they should be obtained in all cases presenting for periodontal treatment and to assess the long-term success of therapy. Diagnostic-quality radiographs for evaluating the periodontium are best obtained with a dental x-ray unit and with the patient under general anesthesia. The standard full-mouth radiographic survey contains a minimum of 6 views, and with practice, can be obtained with minimal effort and time. Interpretation of dental radiographs, however, requires a keen understanding of the normal radiographic anatomy of a tooth and its supporting structures. The radiographic diagnosis of periodontal disease is characterized by rounding of the alveolar crest with loss in continuity of the lamina dura, widening of the periodontal ligament space, and loss of alveolar crest height.
