All patients were treated with NSPT during the intervention period. Serum levels of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), hs-C-reactive protein (hs-CRP), superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), periodontal indices including clinical attachment loss (CAL), bleeding on probing (BOP), pocket depth (PD), and plaque index were evaluated in all subjects pre- and post-intervention.Results: Following 8 weeks of ginger treatment with NSPT, significant reductions were observed in the mean levels of IL-6 (p=0.001), hs-CRP (p=0.03), TNF-α (p=0.007), CAL, and PD (p<0.001) in the intervention group. The mean serum levels of SOD and GPx were significantly increased in the intervention group after the intervention (p=0.001 and 0.002, respectively). At the end of the study, the mean changes of GPx were significantly higher in the intervention group compared with the control group (p=0.04). Also, after the administration of the ginger with NSPT, significant decrease occurred in the mean change of IL-6 (p=0.009), hs-CRP (p=0.049), TNF-α (p=0.049), CAL (p=0.003), and PD (p=0.04) compared with the control group.Conclusion: It is recommended that ginger supplementation along with NSPT may be effective in the improvement of inflammation, oxidative, and periodontal status in T2DM with CP.Keywords: type 2 diabetes mellitus, periodontal disease, ginger, inflammation, antioxidant enzymes
