title: [Periodontal disease in type 2 diabetes patients with and without chronic renal failure].
abstract: OBJECTIVE
  To estimate and compare periodontal disease prevalence (PD) in two groups of patients with type 2 diabetes (T2D), with and without end stage renal disease (ESRD) and dialysis.
  
  
  METHODS
  Using a cross sectional design, two groups of patients with type 2 diabetes were examined in two general hospitals belonging to Instituto Mexicano del Seguro Social in San Luis Potosí. Group A were patients with ESRD and dialysis; Group B, patients with serum creatinine < 2.0 mg/dL. The WHO Community Periodontal Index (CPI) was used to assess PD. 233 patients were examined among which 172 had functional tooth, suitable for PD evaluation.
  
  
  RESULTS
  71 patients integrated group A; their mean age was 56.2 +/- 11.8 years. 101 patients integrated group B, their mean age was 56.7 +/- 11.9 years (p = 0.768). Elapsed time from T2D diagnosis was 221 +/- 86 months for group A, and 126 +/- 101 months for group B (p < 0.001). Poor oral hygiene was found in 39.8 % of group A patients, and 34.6 % of group B patients (p = 0.133). PD prevalence, with CPI scores 3 and 4, was 63.4 % for group A, and 72.3 % for group B (p = 0.216). Multiple linear regression analysis found PD severity associated to ageing (p < 0.001), poor oral hygiene (p < 0.001) and for group A a shorter time from T2D diagnosis to ESRD (p = 0.0315). ESRD hemodialysis patient's PD was more severe than that of peritoneal dialysis patients (p < 0.03).
  
  
  CONCLUSIONS
  both groups had high prevalence of PD and poor oral hygiene. Patients treated with haemodialysis had more severe PD than peritoneal dialysis patients. A shorter time from DM diagnosis to ESRD was found associated to more severe PD.
