OBJECTIVES This study aimed to investigate the role and the possible mechanisms involved in the immunoregulation of experimental periodontitis by Th17/Treg. MATERIALS AND METHODS Experimental periodontitis was established by silk thread ligation with Porphyromonas gingivalis daubing in the bilateral maxillary second molar of Male Sprague-Dawley (SD) rats. Alveolar bones were scanned by Micro-...

AIM The aim of this study is to investigate the effect various dietary nutrients in aggressive periodontitis patients. MATERIALS AND METHODS A total of 85 patients were selected and divided into two groups, 45 patients are with aggressive periodontitis and 40 patients are healthy. Periodontal parameters such as oral hygiene index, Russels periodontal index and radiograph were taken. The food ...

The pathogenesis of periodontitis involves anaerobic oral bacteria as well as the host response to infection and several drugs have been developed which can curtail these deleterious effects. Proanthocyanidin, a novel flavanoid extracted from grape seeds, has been shown to provide a significant therapeutic effect on endotoxin (Escherichia coli) induced experimental periodontitis in rats. In thi...

To investigate the correlation between postmenopausal osteoporosis (PMO) and the pathogenesis of periodontitis, ovariectomized rats were generated and the experimental periodontitis was induced using a silk ligature. The inflammatory factors and bone metabolic markers were measured in the serum and periodontal tissues of ovariectomized rats using an automatic chemistry analyzer, enzyme-linked i...

The subgingival bacterial floras of naturally occurring gingivitis in adults and children were characterized and compared with the floras of other periodontal conditions previously studied. The composition of the gingivitis floras was found to be distinct from that of floras associated with health or with moderate, severe, or juvenile periodontitis. There were no major differences between the f...

Adiponectin is an adipokine that sensitizes the body to insulin. Low levels of adiponectin have been reported in obesity, diabetes and periodontitis. In this study we established experimental periodontitis in male adiponectin knockout and diet-induced obesity mice, a model of obesity and type 2 diabetes, and aimed at evaluating the therapeutic potential of adiponectin. We found that systemic ad...
