Abstract
Objective: To evaluate the prevalence of self-reported awake and sleep bruxism and its association to sleep characteristics among dental students. Methods: A cross-sectional study was conducted with 153 students of a Brazilian Dental School. Students who accepted to participate answered a questionnaire evaluating their sex, age, place of living, paid work, nocturnal paid work, hours of sleep per night, time to fall asleep, sleep quality, if participant had a bedroom partner, if participant is quiet on bed while sleeping and intake of sleep medication. Information on intake of energy drink, if participant wake up overnight, if participant wake up tired and it has been difficult to concentrate on daily activities was also collected. Awake and sleep bruxism was based on self-report. Descriptive analysis and chi-square test were carried out. Results: Most students were female (73%) and mean age was 21 years old (±3.25). The prevalence of self-reported awake and sleep bruxism was 36.5% and 11.3%, respectively. Most participants rated their sleep quality as good (57.2%) and reported that they woke up feeling tired (52.6%). Intake of sleep medication in the last 30 days (P=0.002), waking up overnight and taking over an hour to sleep again in the last 30 days (P=0.005) and waking up feeling tired (p=0.012) were associated factors to self-reported awake bruxism. Conclusion: The prevalence of self-reported awake bruxism was higher than the prevalence of sleep bruxism among dental students. Intake of sleep medication, waking up overnight and taking over an hour to sleep again and waking up tired were can be indicators of the presence of awake bruxism in dental students.
