Study of Periodontal Bacteria in Diabetic Wistar Rats: Assessing the Anti-Inflammatory Effects of Carvacrol and Magnolol Hydrogels.

Periodontal disease and diabetes often co-occur; both are characterized by chronic inflammation. This study aimed to investigate the anti-inflammatory effects of carvacrol and magnolol when incorporated into a periodontal hydrogel and topically applied to Wistar rats with diabetes-associated periodontal disease. Forty male albino Wistar rats were divided into four groups: PD (induced diabetes and periodontitis), PDC (induced diabetes and periodontitis treated with carvacrol), PDM (induced diabetes and periodontitis treated with magnolol), and PDCM (induced diabetes and periodontitis treated with both carvacrol and magnolol). Post treatment, gingival tissue samples were collected to measure levels of the pro-inflammatory cytokines IL-6 and TNF-α. The PDCM group exhibited significantly lower levels of interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α) compared to the PD group. The combined application of a periodontal hydrogel containing carvacrol and magnolol may significantly reduce gingival inflammation in rats with diabetes-associated periodontal disease.
