简要总结

Present study intended to compare diseased and healthy sites in chronic and aggressive periodontitis with healthy individuals. The investigators suggest that even unaffected healthy sites of both chronic and aggressive periodontitis patients exhibit subclinical inflammation and tissue destruction with decreased fibroblast cell counts and increased inflammatory cell counts. Investigators also suggest that a possible mechanism which might play a role in the disease progression might occur via a disbalance between matrix metalloproteinases and their inhibitors, and increased hypoxia in diseased sites.

详细描述

Periodontal disease disrupts soft tissue metabolism in the gingiva through a decrease in the production of collagen, the quality, and quantity of the connective tissue. The etiology and pathogenesis of chronic periodontitis are mostly revealed however, there are many dark points in the etiopathogenesis of aggressive periodontitis. The existence of periodontal destruction at even one tooth in the mouth increases the risk of further periodontal destruction. However, the incidence of progression of the disease to the unaffected teeth was not demonstrated. Yet, the progression of the disease from diseased sites to healthy sites is likely to occur but no evidence is present comparing healthy and diseased sites of chronic and aggressive periodontitis. Present study aimed to evaluate the histological changes in both diseased and healthy sites in both localized aggressive periodontitis (LAgP) and chronic periodontitis (CP) patients by determining fibroblast and inflammatory cell counts in histologic slides and immunohistochemical staining of enzymes and hypoxia markers in order to better understand the dimensions of this demolition in periodontal disease.
