Resumen
Diabetes mellitus (DM) and periodontitis are chronic conditions with a well-established bidirectional relationship. This interaction not only worsens periodontitis severity but also complicates glycemic control. We aimed to determine whether nonsurgical periodontal treatment reduces glycosylated hemoglobin (HbA1c) levels at 3 and 6 months in type II diabetic patients with periodontal disease.
In this sequential case-control study conducted at the University Dental Clinic in Murcia, Spain, we enrolled thirty diabetic patients. Participants were allocated to either a test group (receiving comprehensive periodontal treatment with scaling and root planing) or a control group (receiving supragingival plaque removal only). Both groups received oral hygiene instructions. We evaluated periodontal parameters (HI, GBI, PPD, CAL) and HbA1c levels at baseline, 3, and 6 months, analyzing data with repeated-measures ANOVA and Bonferroni correction.
The periodontal treatment group demonstrated statistically significant reductions in HbA1c levels at both 3 and 6 months post-treatment (p < 0.05). In contrast, we observed no significant changes in the control group.
Our findings indicate that periodontal disease associates with elevated HbA1c levels in diabetic patients. Nonsurgical periodontal treatment significantly reduces both periodontal inflammation and HbA1c levels at 3 and 6 months, supporting its integration into comprehensive diabetes management.
