Assessing the Association Between Occlusal Characteristics and Sleep Quality and Stress Levels: A Cross-Sectional Study

초록

Malocclusion can arise due to various causes and may impact not only temporomandibular joint (TMJ) disorders but also overall systemic health. This study aimed to evaluate the association of individual occlusal characteristics with sleep quality and stress levels in female college students. Occlusal analysis was conducted using T-Scan III on 84 participants (age: 21.7 +/- 2.09), while sleep quality and stress levels were assessed using the Korean version of the Pittsburgh Sleep Quality Index and self-reported stress questionnaires, respectively. Sleep quality was categorized as "good sleeper" (<= 5 points) or "poor sleeper" (>5 points). Stress levels were classified as Normal (<= 13), Initial stress (14-16), Moderate stress (17-18), or Severe stress (>= 19). The results indicated no significant differences in sleep quality based on occlusal characteristics. However, participants with Type A occlusion (posterior contact without anterior contact) exhibited higher stress scores than those with Type B occlusion. Correlation analysis showed a weak negative association between stress scores and occlusion type, but no significant relationship was found between occlusal characteristics, sleep quality, and stress levels. In conclusion, individual occlusal characteristics have limited explanatory power regarding their effects on sleep quality and stress.
