Abstract
Background: Despite various treatment approaches for bruxism, there is limited evidence comparing exercise therapy and occlusal splints, highlighting the importance of this study.
Objectives: To compare the effects of a 6-week jaw exercise (JE) program with combined jaw and posture exercises (JP) on pain and mandibular motion in patients with probable sleep bruxism. The secondary objectives were to evaluate the effects of the interventions on oral parafunctions, posture, and sleep quality.
Methods: Sixty-three patients with probable sleep bruxism were randomly assigned to JE, JP, or Occlusal Splints (OS) groups at the University Hospital. Pain levels were assessed using the visual analogue scale (VAS), and the maximum oral opening was measured using a calliper. Secondary outcomes included oral parafunctions, evaluated via the Oral Behaviours Checklist, and posture, assessed using craniovertebral and craniohorizontal angles. Assessments were performed at baseline, post-treatment (6th week), and 12th week follow-up. Data were analysed using repeated measures ANOVA (Group × Time).
Results: All groups demonstrated significant pain reductions (p < 0.05), but none of the groups showed superiority (p > 0.05). Mouth opening improved significantly only in the JE group (p < 0.05), with no intergroup differences (p > 0.05). Improvements in oral parafunctions occurred in the JE and JP groups (p < 0.05), but the differences between the groups were not significant (p > 0.05). No significant changes were observed in the craniovertebral or craniohorizontal angles (p > 0.05). No adverse events were observed in any intervention group.
Conclusion: This trial found no substantial superiority between interventions. Exercise-based therapies (JE and JP) and OS similarly improved pain, mouth opening, and oral parafunctions in bruxism patients, with no postural changes. Further studies should explore long-term effects in diverse populations.
期刊介绍：
Journal of Oral Rehabilitation aims to be the most prestigious journal of dental research within all aspects of oral rehabilitation and applied oral physiology. It covers all diagnostic and clinical management aspects necessary to re-establish a subjective and objective harmonious oral function.
Oral rehabilitation may become necessary as a result of developmental or acquired disturbances in the orofacial region, orofacial traumas, or a variety of dental and oral diseases (primarily dental caries and periodontal diseases) and orofacial pain conditions. As such, oral rehabilitation in the twenty-first century is a matter of skilful diagnosis and minimal, appropriate intervention, the nature of which is intimately linked to a profound knowledge of oral physiology, oral biology, and dental and oral pathology.
The scientific content of the journal therefore strives to reflect the best of evidence-based clinical dentistry. Modern clinical management should be based on solid scientific evidence gathered about diagnostic procedures and the properties and efficacy of the chosen intervention (e.g. material science, biological, toxicological, pharmacological or psychological aspects). The content of the journal also reflects documentation of the possible side-effects of rehabilitation, and includes prognostic perspectives of the treatment modalities chosen.
