Study the effect of non-surgical periodontal therapy on cystatin C levels in gingival crevicular fluid and serum in both healthy patients and patients with renal impairment. The number of participants is 30 individuals, divided into three groups receiving conservative periodontal treatment (scaling and root planing):Systemically and periodontally healthy patients, Patients with periodontitis without systemic diseases, and Patients with periodontitis and chronic kidney disease. The study also aims to determine the relationship between the severity of periodontal disease and kidney function by measuring cystatin C levels, which is an important biomarker for both conditions. Additionally, it seeks to assess whether non-surgical periodontal therapy can be included in the treatment protocols for kidney patients to improve their quality of life.
Periodontal diseases, particularly gingivitis and periodontitis, are common inflammatory conditions affecting the tooth-supporting tissues. These diseases induce both local and systemic inflammatory responses, which may impact other organs, including the kidneys. Cystatin C (CSTC) is an inhibitor of cysteine proteases and is considered an important biomarker for kidney function, as its serum levels rise in cases of renal impairment. Periodontal diseases may contribute to elevated serum cystatin C levels due to systemic inflammation caused by bacterial infection and inflammatory mediators circulating in the bloodstream. On the other hand, non-surgical periodontal therapy (e.g., scaling and root planing) may reduce both local and systemic inflammation, potentially improving cystatin C levels and kidney function. This study aims to: Assess and compare cystatin C levels in serum and gingival crevicular fluid (GCF) among healthy individuals and patients with periodontitis، Examine the effect of non-surgical periodontal therapy on serum and GCF cystatin C levels in patients with renal impairment compared to healthy controls، and Analyze the relationship between periodontitis severity and kidney function by correlating cystatin C levels with other renal markers (e.g., glomerular filtration rate).

Non-surgical periodontal therapy involves the removal of bacterial plaque and calculus from tooth surfaces and root surfaces beneath the gum line using manual or ultrasonic instruments. This treatment is performed for patients with periodontitis to improve gum health and reduce inflammation. Serum cystatin C levels will be compared before and after treatment between healthy patients and those with renal impairment.

Change in Cystatin C levels after periodontal therapy
Comparison of serum Cystatin C concentration (mg/L) between baseline and 4 weeks post non-surgical periodontal treatment (scaling and root planing) in periodontitis patients with and without chronic kidney disease.
Time frame: Baseline (before treatment) and 4 weeks after completion of periodontal therapy
