Influence of nonsurgical periodontal therapy on serum hemoglobin levels among patients with type 2 diabetes mellitus: A cross-sectional study

Aim: The present study was carried out to examine the association between periodontitis and glycated hemoglobin (HbA1c) in Type 2 diabetes mellitus adults. The objective of the study was to assess the effect of nonsurgical periodontal therapy on serum levels of HbA1c in patients with Type 2 diabetes mellitus and moderate-to-severe periodontitis. Material and Methods: The study population consisted of 78 Type 2 diabetes mellitus patients aged 30–70 years suffering from chronic generalized periodontitis. The patients were selected randomly from among the patients reporting at medicine outpatient department from July 2018 to August 2019. They were assessed for the presence or absence of gingival bleeding, presence or absence of periodontal pockets, and loss of attachment using the Community Periodontal Index (World Health Organization, 2013). Data were analyzed using the statistical package SPSS (version 21.0) and paired t-test at P < 0.05. Results: The mean reduction in haemoglobin levels of patients with moderate to severe periodontitis were significantly reduced by 1.19 in Group I, 0.51 in Group II, and 0.09 in Group III respectively after 3 months of nonsurgical periodontal therapy. This periodontal therapy was clinically effective and had a significant effect on the participant's glycemic control. Conclusion: This periodontal therapy was clinically effective and had a significant effect on the participant's glycemic control.
