Purpose: The aim of this study was to evaluate the sleep macrostructure and the bruxism of individuals with Monosymptomatic Nocturnal Enuresis (MNE) – (study group - SG) and compare with individuals without MNE (control group - CG) by polysomnography examination. Methods: After applying the inclusion and exclusion criteria, the convenience sample was formed with 30 individuals aged 07 to 17 years (average 10.7), 13 girls and 17 boys. The data were obtained by the EMBLA N7000® polygraph, using submental electrodes, thoracic and abdominal straps, nasal flow through nasal pressure cannula and thermistor, pulse and oxygen saturation with pulse oximeter. For macrostructure evaluation, electrodes were placed on the scalp. The criteria for the diagnosis of bruxism followed the guidelines of the American Association of Sleep Medicine (AASM, 2017) manual and evaluated the phasic muscle activities, when less than 3 burst occurred in a period of 0.25 to 2 seconds, tonic, when it occurred. 1 burst lasting longer than 2 seconds and both in each phase of sleep (REM and Non-REM).Results: The electroneuromyographic variables revealed presence of muscle activity, regardless of whether it was phasic or tonic, in some sleep phase in both groups. In the REM sleep phase, no patient in the control group showed tonic activity. However, 41.2% of enuretic patients had bruxism at this stage. Regarding bruxism with phasic activity, no significant differences were observed between the groups, age, mean desaturation index and Arousal in any sleep phase (REM and N-REM). However regarding muscle activity enuretic patients had higher tonic episodes both in the REM phase (p = 0.008) and in the N-REM phase (p = 0.016). Other variables such as age, arousal and mean desaturation index did not influence the presence of tonic episode (p> 0.05). Conclusion: Individuals with MNE have higher tonic activity during sleep than individuals without MNE.
