Abstract
BACKGROUND: Periodontitis, a chronic inflammatory disease affecting the supporting tissues around the teeth, causes significant inflammatory and oxidative changes in cardiac tissue. Crocin is the active constituent of Crocus sativus (saffron) which has antioxidant properties and is protective against cardiovascular disturbances. OBJECTIVES: The present study aimed to investigate the protective effects of crocin on periodontitis-induced oxidative/inflammatory cardiac degeneration in rats in vivo. MATERIAL AND METHODS: Thirty female Sprague Dawley rats were randomly divided into 3 groups: control group, periodontitis group (PD) and periodonditis plus crocin group (PD+Cr). Experimental periodontitis was induced by placing silk ligatures on the maxillary second molar teeth for 30 days. Afterward, crocin (100 mg/kg body weight/day) was administered to the PD+Cr group and saline was administered to the PD group and the control group for 15 days. The subjects were sacrificed on the 45th day. RESULTS: Histological and biochemical analyses demonstrated that inducing periodontitis caused obvious damage to cardiac tissues which was significantly ameliorated by crocin (p < 0.05). Significant improvements in bone resorption parameters (cross-linked C-telopeptide of type I collagen and bone alkaline phosphatase) were also observed in the PD+Cr group (p < 0.05). In addition, crocin caused significant reductions of malondialdehyde levels and total oxidant score while antioxidant levels (glutathione, superoxide dismutase, total antioxidant score, and catalase) were significantly higher in PD+Cr group (p < 0.05). CONCLUSIONS: This study reveals that periodontitis may cause oxidative damage in cardiac tissue and crocin improves periodontitis-induced degenerative changes in heart tissue, which is associated with its antioxidant properties.
