title: Bidirectional Relationship between Chronic Kidney Disease & Periodontal Disease.
abstract: Non communicable diseases (NCDs) affect the life of an individual in terms of mortality, morbidity and financial crises. Main NCDs are diabetes mellitus (DM), cardiovascular diseases (CVD), pulmonary diseases, osteoporosis and chronic kidney diseases (CKD). About 40% of the total deaths can be controlled by eliminating the risk factors for NCDs. Periodontitis have recently been labeled as an important potential risk factor for NCDs. CKD affect the oral health status of patients by inducing gingival hyperplasia, xerostomia, calcification of root canals and delayed eruption of teeth. Periodontitis increases systemic inflammatory burden leading to worsening of CKD which in turn has been has been found to negatively affect CKD of patients on hemodialysis therapy by altering their serum albumin and C-reactive protein levels. As hypoalbuminemia leads to increased mortality in CKD patients, it needs to be avoided by reducing systemic inflammatory burden in patients receiving HD therapy. Treating periodontal disease could be one factor that might decrease the systemic inflammatory burden and thereby improve quality of life of these patients.
  
  
  METHODS
  Data from descriptive, cross sectional and longitudinal studies published between 2000 and 2012 were included. Data searches based on human studies only.
  
  
  METHODS
  The key words, periodontitis, chronic kidney disease and hemodialysis, on MEDLINE, approximately 120 studies were identified. 35 of them were relevant to all three keywords. Most of them were cross sectional studies and total 7 clinical trials were identified regarding checking of serum levels after periodontal therapy with variable results.
  
  
  CONCLUSIONS
  Patients with CKD have higher prevalence of periodontal disease while non-surgical periodontal therapy has been indicated to decrease the systemic inflammatory burden in patients with CKD specially those undergoing HD therapy.
