Abstract:Objective To investigate the effect of periodontal treatment on metabolism in patients with type 2 diabetes with periodontitis. Methods Totally 70 patients with type 2 diabetes with periodontitis underwent periodontal treatment were selected as observation group, and 70 patients without periodontal treatment were selected as control group in the Department of Stomatology of the First Hospital of Jiaxing City from January 2016 to December 2018. The periodontal probing depth (PD), sulcus bleeding index (SBI), attachment loss (AL), fasting blood glucose (FPG), glycosylated hemoglobin (HbA1c), total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL), high density lipoprotein (HDL), visfatin, leptin and tumor necrosis factor-ɑ (TNF- ɑ) levels before and after treatment were measured. Results Before treatment, there were no significant differences in each indicators between the two groups (P > 0.05). After treatment, the PD, SBI and AL values in observation group were lower than those before treatment and in control group (P < 0.05); the difference values of FPG, HbA1c, TC, TG, LDL and HDL in observation group were higher than those in control group (P < 0.05); the difference levels of serum Visfatin, Leptin and TNF-ɑ in observation group were higher than those in control group (P < 0.05). Conclusion Periodontal treatment can correct the disorder of glucose and lipid metabolism and improve the level of glycolipid metabolism in patients with type 2 diabetes with periodontitis.
