Aim: To provide an update of the systematic review by Engebretson and Kocher J Clin Periodontol. 2013 Apr;40 Suppl 14:S153 on the effect of periodontal therapy on glycaemic control of people with diabetes.
Methods: PubMed Literature search restricted to meta-analyses published from 2013 to the present was conducted. The search resulted in seven meta-analyses of RCTs.
Results: Reduction in HbA1c at 3-4 months was reported in all reviews for the treatment group ranging from -0.27% (95% CI: -0.46, -0.07, p = .007) to -1.03% (95% CI: 0.36, -1.70, p = 0.003). At 6 months post-treatment, an HbA1c reduction ranging from -0.02 (95% CI: -0.20, -0.16, p = .84) to -1.18% (95% CI: 0.72%, 1.64%, p < 0.001) was reported.
Clinical relevance: The magnitude of the reduction in HbA1c, which is found to be associated with non-surgical periodontal treatment in patients with diabetes, seems to have clinically significant effects on systemic health, and thus should have a place in the treatment of diabetic patients.
Conclusions: Periodontal treatment (SRP) results in a statistically significant reduction in HbA1C levels at 3 months, with a lower reduction at 6 months.
Keywords: HbA1c; glycaemic control; periodontal therapy.
