To compare the mastication and oral sensory function of individuals with and without sleep bruxism. Methods: The sample comprised 60 volunteers, of which 30 were bruxers (mean age = 30.5 +/- 6.0) and 30 non-bruxers (mean age = 28.6 +/- 3.3).

To compare the mastication and oral sensory function of individuals with and without sleep bruxism. Methods: The sample comprised 60 volunteers, of which 30 were bruxers (mean age = 30.5 +/- 6.0) and 30 non-bruxers (mean age = 28.6 +/- 3.3). Sleep bruxism was clinically diagnosed and confirmed using the Bruxoff (R) device. Mastication was evaluated according to swallowing threshold and masticatory efficiency. Swallowing threshold was determined from the median particle size of Optosil (R), obtained after an individualized number of masticatory cycles, which was first determined by chewing peanuts; masticatory efficiency was estimated by the sieving method. Oral stereognosis test was used to determine the oral sensory function. Variables were compared using one-way ANOVA (p < .05). Results: The median particle size, masticatory efficiency, and oral sensory function did not differ significantly between bruxers and non-bruxers (p > .05). Conclusion: Dentate adults present similar mastication and oral sensory function, despite the presence of sleep bruxism
