Glycemic Control in Diabetes Improved by Total Tooth Extraction Treatment in a Cat

Abstract

A mixed-breed, spayed female cat aged approximately 7 years was brought to our hospital with complaints of left mandibular swelling and anorexia. She was being treated with insulin for diabetes. Oral examination revealed severe periodontitis. We proposed a total extraction treatment. However, due to the owner’s refusal, antibiotic therapy was initiated. After antibiotic administration, the mandibular swelling reduced; however, the anorexia did not improve, and body weight decreased. On the 90th day of illness, total tooth extraction was performed under general anesthesia. Post treatment, the anorexia improved, and her body weight increased. Fasting blood glucose and fructosamine levels decreased. On the 570th day of illness, her appetite was stable, and glycemic control was well maintained. The production of inflammatory cytokines from periodontal lesions might have increased the insulin resistance and impeded glycemic control. Tooth extraction procedures may improve periodontal inflammation, insulin resistance, and glycemic control. As in this case, periodontal disease treatment may help in the treatment of diabetes.
