Objective: To characterize sleep architecture in a population group of adults with sleep bruxism, in general and by sex.
Materials and method: Retrospective descriptive study, with intentional sampling of 33 polysomnographies that identified subjects with sleep bruxism, according to the “cut off” suggested by Lavigne et al (25 events /hour/), between the years 2011-2019. The variables sex, age, weight, height and body mass index (BMI) were considered. Sleep architecture was determined in terms of duration of sleep stages, micro-awakenings, and bruxism events. A descriptive anlysis of the variables was carried out and the results were compared between the sexes.
Results: In the population group, 64% were women and 36% men. The average age was 32.5 years, height 1.65 m, weight 68 kg, with an average BMI of 24.89 (normal weight). Subjects had an average of 387.6 minutes of sleep, 270 minutes in non-rapid eye movement (NREM) and 10.8 in rapid eye movement (REM), with an average of 50 micro-awakenings during the night and 48.64 bruxism events per hour. According to sex, the values in minutes were: NMOR (H:316.2 – M:256.8); MOR (H:105 – M:104.4); microawakenings (H:58.9 – M:45.1); BS events/hour: (H:48.6 – M: 46.6), no significant differences were found between them (p>0.05). Subjects with BS slept, on average, a greater number of minutes in the lateral decubitus position (196.59).
Conclusion: Subjects with BS register certain characteristics in their sleep architecture that must be considered. There was no difference in sleep architecture according to sex.
