12 Chronic gingivostomatitis as a consequence of periodontitis and iatrogenic injuries
There was no history of any oral disease or dental/periodontal therapy until 2 years ago, when the cat received ‘dental with extractions due to heavy accumulation of plaque and calculus’. Within 2 weeks of treatment the cat presented with inappetance and drooling, and gingivostomatitis was diagnosed by the referring veterinary surgeon.
In the last 2 years the cat had undergone five episodes of periodontal treatment. These had consisted of scaling, polishing and extraction (there was no record of which teeth had been extracted). There had been some improvement immediately following each treatment (the cat would start eating), but the inflammatory reaction had flared up again within weeks (the cat would stop eating). Several courses of antibiotics and the administration of long-acting steroid had shown initial improvement and then deterioration within a few weeks. The latest long-acting steroid injection had not had any beneficial effect at all. The cat was referred to us for management of the chronic gingivostomatitis. Prior to referral we requested haematology and biochemistry screen and FeLV and FIV testing to be performed by the referring veterinary surgeon. The cat was found to be negative to both FIV and FeLV and the only blood abnormality was elevated plasma globulins.
Figure 12.1 The front page of the dental record sheet is used to record all clinical findings. 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 disease. 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 so that periodontal attachment level (PAL) can be calculated (GR + PPD) and entered on the record at its precise site in green ink. PAL is a more accurate assessment of attachment loss.
