Abstract
Background and aims. The aim of the present study was to evaluate the result of full scaling and root planning with and
without systemic administration of doxycycline on periodontium and metabolic control in type 2 diabetes mellitus (DM) patients.
Materials and methods. Thirty patients with type 2 DM with poor glycemic control were selected and randomly assigned
into two groups. Case group received scaling and root planning and doxycycline (SRP + Doxy) and control group received only
SRP. Probing pocket depth (PD) and bleeding on probing (BOP) as the most important indicators for periodontal health were recorded
at baseline, 3- and 6-month follow-up. Fasting blood sugar (FBS), glycated hemoglobin (HbA1c), total cholesterol (TC),
and triglyceride (TG) were analyzed before and after periodontal treatments.
Results. A statistically significant reduction was observed for PD and BOP for the treatment groups. HbA1c levels in SRP group
decreased more significantly than SRP + Doxy group (9.15 ± 0.76 to 7.73 ± 1.41% and from 8.41 ± 0.49 to 7.88 ± 1.77%, respectively).
Conclusion. Non-surgical periodontal treatment is associated with improved periodontal health and glycated control in DM
type 2 patients and could be considered as an important part of the diabetic patient care.
