Brief Summary
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.

Outcome Measures
Primary Outcomes (1)
Fibroblast and total inflammatory cell counts
Fibroblast and total inflammatory cell counts in the groups were determined in a standardized 1000 micrometer square area with histomorphometric evaluation.
Biopsies were obtained a day after initial examinations, histological analysis were performed 2 weeks after.
Secondary Outcomes (1)
Immunohistochemical staining
Biopsies were obtained a day after initial examinations, histological analysis were performed 2 weeks after
Study Arms (5)
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.

Eligibility Criteria
Healthy individuals, chronic periodontitis patients, and localized aggressive periodontitis patients older than 30 years old and younger than 45 years old were enrolled. The age was specifically chosen because aging changes periodontal and gingival tissues independently of other variables. Any possible factor which might alter connective tissue metabolism were excluded.
You may qualify if:
- Age range from 30 to 45, the existence of at least 20 functioning teeth, no history of smoking, systemical health, no antibiotic use within 6 months, no periodontal therapy within 6 months, no pregnancy or lactation, no drug use, in addition; For healthy individuals, the existence of oral health
- For localized aggressive periodontitis, the existence of the disease at least for 5 years, the presence of both healthy and diseased sites in the same patient.
- For chronic periodontitis, the existence of the disease at least for 5 years, the presence of both healthy and diseased sites in the same patient.
You may not qualify if:
- Patients younger than 30 older than 45 years old, the absence of occlusion, drug use, pregnancy/lactation, smoking, previous antibiotic use, previous periodontal therapy, the existence of any systemical disease.
