9 Systemic effects of periodontitis
The dog was being treated for septic pneumonia, with consolidation of the left cranial lung lobe likely to be secondary to his periodontal disease. He also had tracheitis and collapsing trachea. He was referred to us to manage the periodontal disease. No history of any previous oral or dental disease or treatment was available to us.
Figure 9.1 Dental record. All clinical findings are reported on the front page of the dental record. Normal periodontal probing depth (PPD) is not noted on the dental record to avoid clutter. However, when gingival recession is present, then PPDs are always recorded. True attachment loss is the sum of the recession and probing depth. Remember that periodontitis is a site-specific disease. PPD is recorded on the occlusal view of the tooth on the dental record so that you can easily identify the precise site of the disease.
Figure 9.2 Extensive alveolar bone loss. The lower incisor and canine teeth were absent and there had been extensive bone loss. In fact, the bone loss had resulted in destruction and separation of the mandibular symphysis, and the left and right mandibles were freely movable.
