Comparison of Temporomandibular Joint Disorders Between Patients Treated with Hemodialysis versus Peritoneal Dialysis

Abstract

Objective: The primary aim of this study was to investigate the difference, if any, in the frequency of temporomandibular joint disorders between patients with end-stage kidney disease (ESKD) and healthy individuals. Our secondary aim was to compare the frequency of temporomandibular joint disorders between patients with end-stage kidney disease treated with hemodialysis versus peritoneal dialysis.

Methods: All participants completed a questionnaire and underwent a dental evaluation to confirm temporomandibular joint disorder.

Results: The frequencies of temporomandibular joint disorders were 13% and 8.9% in the patient and control groups (P =.35), respectively, and 13.4% and 12% in the hemodialysis and peritoneal dialysis groups, respectively (P = 0.85).

Conclusions: We observed no difference in temporomandibular joint disorder frequency between patients with end-stage kidney disease who received hemodialysis and peritoneal dialysis as kidney replacement therapy and between patients with ESKD and healthy individuals. Further large-scale studies are warranted to gain a deeper understanding of this topic.
