Background: Periodontal disease is a chronic disease causing an inflammatory process that affects various organs and is as-sociated with an increased risk of many diseases, including bone and cardiovascular disease.
Aim: The aim of this study was to establish the prevalence of periodontal disease in continuous patients scheduled for hip or knee replacement surgery.
Methods: The study was a prospective, epidemiological analysis performed in consecutive patients scheduled for total joint (hip or knee) replacement surgery. Patients enrolled into the study were screened for classical risk factors and had a dental evaluation performed for the diagnosis of periodontal disease.
Results: The study population consisted of 228 patients. A total of 137 (60.1%) patients were scheduled for a hip replace-ment surgery, while 91 (39.9%) had a knee replacement. The mean age of the study population was 66.8 ± 12.2 years, and 83 (36.4%) patients were male. A clinically significant disease was present in 65 (28.5%) cases, while all (100%) of the patients had at least minimal signs of periodontal disease. In patients with periodontal disease the percentage of tartar involvement of the teeth was 33.1 ± 26.8%, mean dental plaque coverage was 48.1 ± 29.8%, and bleeding occurred at a rate of 35.4 ± 29%. As for the hygiene level, it was generally poor in the majority of patients with periodontal disease. No differences in terms of baseline risk factors were present between patients with and without periodontal disease.
Conclusions: In conclusion, periodontal diseases are highly prevalent in patients undergoing hip and/or knee replacement surgery. The presence of the periodontal disease is possibly associated with a worse prognosis and should be treated.
