title: The dental health status of dialysis patients.
abstract: BACKGROUND
  The number of patients with kidney failure who require dialysis is growing by 10% to 15% annually, and the likelihood that dentists will treat such patients is also increasing. The dental care of patients undergoing dialysis can be complex, given the prevalence of comorbid conditions such as diabetes, hypertension, renal osteodystrophy and immunosuppression, the presence of nondental prosthetic devices, and the use of antihypertensives and anticoagulants or antiplatelet agents. These patients appear to be predisposed to a variety of dental problems such as periodontal disease, narrowing of the pulp chamber, enamel abnormalities, premature tooth loss and xerostomia. Dental care, as well as primary preventive measures, seems to have been neglected in these patients. Therefore, a study of the dental health of dialysis patients was undertaken.
  
  
  METHODS
  Completion of a questionnaire and a noninvasive oral examination was obtained from hemodialysis and peritoneal dialysis patients registered in the dialysis program at St. Paul's Hospital in Saskatoon, Saskatchewan, as of March 1, 1999. Information was also gathered from the medical chart. Medication history as well as history of diabetes, hypertension, and nondental prosthetic devices were also recorded.
  
  
  RESULTS
  Of 226 dialysis patients in central and northern Saskatchewan, 147 were interviewed and examined. Of these, 94 (64%) were dentate, and the same number had been on dialysis for a mean of more than 2 years; about a third were diabetic, almost all were hypertensive and all had nondental prosthetic devices or arteriovenous fistulae, or both. Sixty (64%) of the dentate patients were candidates for kidney transplantation. Most of the dentate patients reported brushing once or more daily, but they flossed infrequently or never. Dental visits were infrequent, less than every 5 years in 59 (63%) of the dentate patients. Findings in the dentate group included increased tooth mobility, fractures, erosion, attrition, recession, gingivitis and a high plaque index. A patient's dentist was contacted if the patient had seen him or her since starting dialysis (31 of the 94 dentate patients). Most (81%) of the dentists were aware that they were treating a dialysis patient. Medication records were incomplete for 29% of the patients, and only 2 (6%) of the patients had received antibiotic prophylaxis despite the fact that all had prosthetic devices or arteriovenous fistulae.
  
  
  CONCLUSIONS
  We conclude that the dental health of dialysis patients is poor and requires greater attention.
