Effects of the bite splint 15-day treatment termination in patients with temporomandibular disorder with a clinical history of sleep bruxism: a longitudinal single-cohort study

Abstract

The aim of this study was to assess the effects of bite splint (BS) treatment termination in patients treated for temporomandibular disorder (TMD) and sleep bruxism (SB). This longitudinal single-cohort study assessed 30 patients (29.5 ± 7.8 years old, 86.7% women) who were successfully treated with BS for SB and TMD for 30 days to 6 months prior to termination of the use of BS. The Research Diagnostic Criteria for TMD Axes I and II, Sleep Assessment Questionnaire, Beck Depression Inventory, and BiteStrip were used to assess TMD signs and symptoms, sleep disorders, depression, and SB at baseline and after 15 days of BS disuse. TMD symptoms, including the disability points, characteristic pain intensity, and present pain at rest, increased significantly (P < 0.05). After 15 days of BS termination, there were no significant differences in SB and depression levels, sleep quality, and TMD signs. In patients with TMD and SB, BS treatment cessation is not recommended.
