Oral and salivary changes in patients with end stage renal disease (ESRD): a two year follow-up study.
OBJECTIVE
To compare oral health, salivary flow rate, xerostomia and thirst in end stage renal disease (ESRD) patients remaining on dialysis treatment and after renal transplantation.


METHODS
Longitudinal observation.


METHODS
ESRD patients recruited from dialysis centres in Amsterdam, The Hague and Utrecht, The Netherlands.


METHODS
At baseline and after two years, salivary flow rates, xerostomia and thirst were determined in 43 ESRD patients. The number of decayed missing filled teeth/surfaces (DMFT/DMFS) was recorded, and periodontal status assessed.


RESULTS
After renal transplantation (n = 20), the salivary flow rate increased significantly from UWS = 0.30 +/- 0.21 ml/min to 0.44 +/- 0.29 ml/min (p <0.001) and the level of xerostomia and thirst decreased. After two years, the percentage of bleeding on probing in dialysis patients (n = 23) decreased from 29.5 +/- 25.4% to 10.3 +/- 12.3%, (p <0.05). No differences in DMFT and DMFS were observed between dialysis and renal transplant patients.


CONCLUSIONS
DMFT, dental plaque, gingival bleeding and periodontal indices did not change remarkably after two years, comparing dialysis and renal transplant patients. Renal transplantation enhances salivary flow and decreases symptoms of xerostomia and thirst, and hence enhances the potential to improve the quality of life of affected individuals.
