[Effect of nonsurgical periodontal therapy on glycemic control in type 2 diabetes patients with chronic periodontitis].

PURPOSE

To investigate the effect of nonsurgical periodontal therapy on blood glucose control in patients with type 2 diabetes mellitus (T2DM) and chronic periodontitis, as well as the sensitive population.

METHODS

A total of 120 patients with T2DM and chronic periodontitis who were admitted to the Department of Endocrinology at Lishui City People's Hospital from March 2022 to March 2023 were randomly divided into experimental group and control group, with 60 patients in each group. All patients received oral health education, and their general information, community periodontal index (CPI), attachment loss (AL), fasting plasma glucose (FPG), and haemoglobin A1c (HbA1c) were collected. The experimental group received periodontal scaling and root planing. Three months later, CPI, AL, FPG, and HbA1c were measured. Stata 15.0 software was used for statistical analysis.

RESULTS

After periodontal scaling and root planing, the CPI, FPG, and HbA1c in the experimental group were significantly lower than those before treatment(P＜0.01) and those in the control group(P＜0.05). AL in the experimental group was also significantly lower than before treatment(P＜0.05) and the control group (P＜0.05). The change of FPG after treatment was positively correlated with the duration of diabetes (P＜0.01) and the baseline CPI(P＜0.05), but negatively correlated with whether suffering from hypertension(P＜0.05). It was also negatively correlated with the FPG level before treatment (P＜0.01). The change of HbA1c after treatment was positively correlated with the duration of diabetes(P＜0.05) and negatively correlated with the HbA1c level before treatment(P＜0.01).

CONCLUSIONS

Nonsurgical periodontal therapy is helpful to blood sugar control of type 2 diabetes patients with periodontitis. Patients with higher baseline CPI levels and longer disease durations show greater improvement in glycemic control after treatment.
