Περιγραφή
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.

| Healthy individuals Gingival biopsies of healthy individuals who had no systemic or oral disease or condition. | |
| Unaffected sites of CP Chronic periodontitis patients had teeth affected from destruction and some teeth were unaffected. Gingival biopsies of chronic periodontitis patients were taken from sites which were not affected by periodontal destruction. | |
| Affected sites of CP Chronic periodontitis patients had teeth affected from destruction and some teeth were unaffected. Gingival biopsies of chronic periodontitis patients were taken from sites which were affected by periodontal destruction. | |
| Unaffected sites of LAgP Like chronic periodontitis, aggressive periodontitis patients had also teeth affected by destruction and some teeth were unaffected. Gingival biopsies of aggressive periodontitis patients were taken from sites which were not affected by the periodontal destruction. | |
