SB patients do not only present with higher levels of daytime fatigue or potential sleepiness, but may also exhibit sleep quality impairments directly related to the total duration of bruxism occurrences. Beyond increased and abnormal teeth attrition, Sleep Bruxism (SB) may also directly impact sleep quality and related symptoms. We aimed at unraveling the existing relationships between nocturnal SB events (i.e. type, duration and sleep stage incidence) and structured clinical evaluations regarding sleep related daytime symptoms.
