Torus palatinus in end-stage renal disease patients receiving peritoneal dialysis: Does renal osteodystrophy play a role?

Abstract

Background: Our aim was to investigate the prevalence, size, locations, and shapes of torus palatinus (TP) in end-stage renal disease (ESRD) patients receiving peritoneal dialysis (PD) in order to analyze the relationship between the TP size and duration of PD. Materials and methods: During 2007, 91 ESRD patients receiving PD were studied using dental examinations at our outpatient clinic. Results: The prevalence of TP was 41.7% (n=38). Most cases of TP were 2 cm (6.8±3.6 years) than patients with TP size of < 2 cm (3.5±2.6 years). Conclusions: The higher prevalence of TP and different TP shape (spindle) in comparison with our previous study and the significant relationship between duration of PD and TP size might be due to an underlying disorder, such as renal osteodystrophy.
