Implication

Cross-sectional study finds distinct sleep position habits linked to bruxism and temporomandibular disorder symptoms in adults, suggesting sleep posture may influence jaw symptom patterns.

Key Points

  • To evaluate the association between sleep position habits and clinical findings of bruxism and temporomandibular disorder-related symptoms in adults.
  • Conducted a cross-sectional study of 300 adults categorized into healthy individuals, those with TMD-related symptoms only, and those with bruxism with or without TMD symptoms.
  • Collected self-reported data on sleep habits, grinding, stress, physical activity, and sleep duration via structured questionnaires.
  • Performed standardized clinical TMJ examinations to assess joint pain, stiffness, and pain during function without device-based monitoring.
  • Sleep position habits differed significantly across the study groups (p = 0.001), with the lateral position being more frequent in healthy participants and the combined lateral-prone position being more frequent in the bruxism group (p < 0.05).
  • Morning jaw pain or headache, TMJ stiffness, and pain during function were significantly elevated in clinical groups relative to healthy controls (overall p < 0.001).
  • No statistically significant differences were observed among the groups regarding age, sex, physical activity levels, or overall sleep duration.
