Nocturnal bruxing events: a report of normative data and cardiovascular response.
Twenty subjects referred to a sleep laboratory for evaluation of sleep apnoea and found not to have any sleep disordered breathing problems were evaluated in this study. Bruxing events were recorded for frequency, duration, association with sleep stage and sleep position. The possible association between leg movements and bruxing events was also evaluated, but did not reveal any common mechanism. This study revealed that heart rate during bruxing events increased on average by 16.6%.
