Positive effect of curcumin on experimental peridontitis via suppression of IL-1-beta and IL-6 expression level.

This study examined the effect of curcumin on T-helper (Th17) and T-regulatory (Treg) cells regarding the mRNA of cytokines/mediators in the gingiva. Thirty-five male albino Wistar rats were divided into four groups: Group 1: periodontitis (n = 9); Group 2: periodontitis with curcumin treatment (n = 8); Group 3: periodontally healthy with curcumin treatment (n = 10); and Group 4: periodontally healthy (n = 8). Curcumin was administered via oral gavage (30 mg/kg/day) for a total of 15 days.

Effect of Curcumin on Systemic T Helper 17 Cell Response; Gingival Expressions of Interleukin-17 and Retinoic Acid Receptor-Related Orphan Receptor γt; and Alveolar Bone Loss in Experimental Periodontitis.

Background: Curcumin has anti-inflammatory and antioxidant effects and is reported to have many biologic activities. The current study examines effect of curcumin on: 1) systemic T helper 17 (Th17) cell response; 2) gingival expressions of interleukin (IL)-17 and retinoic acid receptor-related orphan receptor (ROR) γt; and 3) alveolar bone loss (ABL) in experimental periodontitis.

Methods: Thirty-eight male albino Wistar rats were divided into four groups: 1) group 1 = periodontitis; 2) group 2 = periodontitis with curcumin treatment; 3) group 3 = periodontally healthy with curcumin treatment; and 4) group 4 = periodontally healthy.
