title: Oral health of hemodialysis patients: a cross-sectional study at two German dialysis centers.
abstract: The aim of the study was to investigate the oral hygiene behavior and state of oral health of hemodialysis (HD) patients in Germany. HD patients attending two dialysis centers were asked to participate in the study. Anamneses and oral hygiene behavior were recorded in a questionnaire. Dental examination included the dental status (DMF-T) and the degree of gingival inflammation (PDI: Periodontol Disease Index). Of 129 patients contacted, 54 (42%), aged 63.9 ± 13.0 years (23 women and 31 men), took part in the study. At an average, dialysis was required for 4.1 years. The cause of terminal renal failure was glomerulonephritis in 30% of patients and diabetic nephropathy in 22% of patients. Since dialysis therapy, 63% of the patients (n = 34) only visited a dentist when they had complaints. In 46 cases (85%), the dentist had been informed about the patient's requirement for dialysis, and in most cases (70%), the dental treatment took place on the day after dialysis. The mean DMF-T of the HD patients was 22.1 ± 6.5. The proportion of carious teeth was low (D-T: 0.7 ± 1.2), of missing teeth (M-T) high (16.2 ± 9.3). The median degree of gingival inflammation (PDI) was 1. Availing themselves of dental treatment after patients needed to have dialysis was mostly "complaint oriented." In addition to a high proportion of missing teeth, a good level of restoration of caries was found. The gingiva showed only a low level of inflammatory changes.
