The objective of the study was to describe the average oximetry, heart rate, and apnea events values during sleep, and the activity of masseter and temporal muscles in a group of young adults with SB (Sleep Bruxism). This serial case and observational descriptive study comprised of a sample of 20 young people between 21 and 25 years of age, who were diagnosed with SB through a polysomnography test. Electromyography recordings served to describe the activity conditions of masseter and temporal muscles, while polysomnography was used to obtain measurement values and vital signs. A descriptive statistical analysis accounting for measures of central tendency, absolute and relative frequencies was performed. During mastication, the average masseter and temporal muscle activity values registered at (D: 86) (I: 520), and (D: 340) (I: 510) respectively. While, the average value for hypopnea episodes was (28.9), and (NREM: 93.5) (REM: 93.8) for oximetry. The average heart rate exhibited a value of (NREM: 65.4) (REM: 66.8) beats / minute, while the values for bruxism events registered at (NREM: 135.4) (REM: 120.2) with an index value of (SB events / hour) (40.60). Muscles of mastication characteristics, and vital signs during sleep for subjects with SB can aid in understanding and decision making in treatment.
