[Influence of periodontal non-surgical therapy on serum interleukin 6 expression and carotid artery wall in rats with periodontitis and type 2 diabetes mellitus].

Objective: To study the effect of periodontal non-surgical treatment on serum interleukin-6 (IL-6) expression and carotid vascular wall in a rat model of chronic periodontitis (CP) with type 2 diabetes mellitus (T2DM).

Methods: Twenty-eight 6-week-old SD rats were randomly divided into group A (control group, 7 rats) and group B (T2DM+CP group, 21 rats). According to different intervention measures, group B was randomly subdivided into B1 (natural process), B2 (periodontal mechanical treatment), and B3 (periodontal mechanical treatment + 2% minocycline hydrochloride + systemic metronidazole plus amoxicillin).

Effects of Periodontal Intervention on Levels of Serum High-sensitivity C-reactive Protein and Interleukin 6, and on Carotid Artery in Rats with Chronic Periodontitis and Hyperlipidemia.

Objective: To investigate the effects of nonsurgical periodontal therapy on the serum interleukin 6 (IL-6) and high-sensitivity C-reactive protein (hsCRP) and on the carotid artery in rats with chronic periodontitis (CP) and with or without hyperlipidemia (HL).

Methods: A total of 29 Sprague-Dawley rats were randomly divided into two groups: group A (CP, n = 14) and B (CP + HL, n = 15), and subjected to the corresponding treatment. Groups A and B were further divided into groups A1/B1 (without periodontal interventions) and A2/B2 (with periodontal interventions).
