Periodontitis and overweight or obesity independently change serum levels of leptin, adiponectin, and C-reactive protein (CRP). This research suggests that treating periodontal disease is beneficial in systemic inflammatory response in obese patients.

The aim of this study is to investigate the alterations of serum levels of leptin, adiponectin, and CRP after nonsurgical periodontal treatment (NSPT) in Thai patients with overweight or obesity (Owt/Ob) who did or did not exhibit severe periodontitis (SP) and normal weight (Nwt) patients with or without SP.

29 patients were included in this study. The study participants comprised 6 patients with Owt/Ob who exhibited SP, 11 patients with Owt/Ob who did not exhibit SP, 5 Nwt patients with SP, and 7 Nwt patients without SP. Periodontal disease status was evaluated; serum levels of leptin, adiponectin, and CRP were determined by enzyme-linked immunosorbent assay at baseline, as well as at 3 and 6 months after NSPT.

The outcomes were;
--At 3 months after NSPT, periodontal status was improved in all groups, except Nwt patients without SP.

--Serum levels of leptin and CRP were significantly reduced, while serum levels of adiponectin were elevated after NSPT, regardless of bodyweight or waist circumference.

--Improvement in serum levels of leptin after NSPT was also observed in the Nwt with SP group; these levels did not significantly differ in Nwt patients without SP.

Conclusively, NSPT reduces serum levels of leptin and CRP and enhances serum levels of adiponectin in patients with Owt/Ob, irrespective of periodontitis severity. These results suggest a role for periodontal treatment in the systemic inflammatory response of people with Owt/Ob.
