The purpose of this study is to examine the role of gum disease in affecting the long term prognosis of renal patients. This disease if untreated causes inflammatory response throughout the body. If the subject has gum disease, he/she will be randomly assigned to one of the two treatment groups. The study investigates what happens to inflammatory markers in blood and saliva after you are treated for gum disease.

Condition Intervention
Chronic Kidney Disease
Procedure: Scaling root planing
Procedure: Supragingival Prophylaxis

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single Blind (Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Periodontal Infection and Systemic Inflammation in Renal Patients

Further study details as provided by University of Connecticut Health Center:

Primary Outcome Measures:
  • Serum Interleukin-6 (IL-6) and C-reactive protein (CRP) levels [ Time Frame: 2 months ] [ Designated as safety issue: No ]
    IL-6 and CRP are markers of systemic inflammation and may improve at the end of gum treatment.

Secondary Outcome Measures:
  • Changes in periodontal (gum) clinical presentation and status [ Time Frame: 2 months ] [ Designated as safety issue: No ]
    For the secondary outcome, periodontal variables such as bleeding on probing, probing depth (the depth of the gum sulcus around the tooth), and bacterial plaque score will be evaluated to assess the effectiveness of the intervention and the compliance of the patients
