Tetracycline-based matrix metalloproteinase- (MMP-) inhibitors are currently approved for two inflammatory diseases, periodontitis and rosacea. The current study addresses the therapeutic potential of a novel pleiotropic MMP-inhibitor not based on an antibiotic. To induce experimental periodontitis, endotoxin (LPS) was repeatedly injected into the gingiva of rats on one side of the maxilla; the...

Periodontitis is a multifactorial disease that involves the destruction of hard and soft tissues surrounding tooth. Routine periodontal treatment includes mechanical debridement (surgical non-surgical) systemic administration antibiotics. In contrast, severe chronic periodontitis aggressive tissue bone resorption, damage usually irreversible. these cases, grafts, delivery growth hormones, guide...

Background: The selective removal or inhibition of pathogenic microbes with locally delivered antimicrobials when combined with scaling and root planing is often an effective approach for the managment of chronic periodontitis. Aim: To compare the clinical efficacy of tetracycline fibers and a xanthan based chlorhexidine gel in the treatment of chronic periodontitis. Methods and materials: Thir...

BACKGROUND The production of chemokines by tissue resident cells during inflammation is considered one of the main mechanisms involved in the formation of inflammatory infiltrates. Fibroblasts are the main resident cell type in gingival and periodontal ligament tissues, and their ability to produce chemokine stromal cell-derived factor 1 alpha (SDF-1α) and its receptor CXCR4 under stimulation b...

BACKGROUND Bisphosphonates are potent inhibitors of bone resorption and were shown to inhibit bone resorption in experimental periodontitis by unknown mechanisms. We studied the effect of the aminobisphosphonate sodium alendronate (SA) in experimental periodontitis. Wistar rats were subjected to ligature placement around the second upper left molars. METHODS Animals were treated with SA 0.01 ...

Ghrelin plays a major role in obesity-related diseases which have been shown to be associated with periodontitis. This study sought to analyze the expression of the functional receptor for ghrelin (GHS-R1a) in periodontal cells and tissues under microbial conditions in vitro and in vivo. The GHS-R1a expression in human periodontal cells challenged with the periodontopathogen Fusobacterium nucle...

PURPOSE The objective of this study was to investigate the effect of a dietary flavonoid, kaempferol, which has been shown to possess antiallergic, anti-inflammatory, anticarcinogenic, and antioxidant activities on the periodontium by histomorphometric analysis and on gingival tissue matrix metalloproteinase-1 (MMP-1), MMP-8, and tissue inhibitor of metalloproteinase-2 (TIMP-2) by biochemical a...
