Objectives <p>The aim of the present research is to compare, in a group of healthy young individuals, the number of sleep bruxism (SB) events with the use of two different electromyographic (EMG) devices, which adopt two different protocols for scoring the events.</p> Materials and methods <p>The study was performed on 10 individuals recruited at the University of Siena, Italy. Participants were asked to perform one night of sleep-time recording wearing simultaneously, in their home environment, two different EMG devices, the Bruxoff (Bruxoff^®, Turin, Italy) and the dia-BRUXO (dia-BRUXO, Biotech-Novations, Sanremo, Italy). SB events were identified by the Bruxoff software algorithm as the EMG peaks of an amplitude that exceeds 10% of the maximum voluntary contraction (MVC) performed by the subject before the start of the registration, and that are preceded by a 20% increase in the heart rate compared to the baseline. Conversely, the dia-BRUXO software identified the EMG peaks exceeding 10% of the maximum contraction (MC) recorded during the entire registration period. Both devices were set to count the events lasting 1–5&#xa0;s. After each night of recording, data was downloaded through the dedicated software of each device, which generates a report with the number of sleep bruxism events.</p> Results <p>All the recruited participants completed the registrations at the first attempt without reporting any detachment of the electrodes. The Pearson test showed a strong correlation between the number of SB events scored by the two devices (<i>r</i> = 0.9613, <i>p</i> &lt; 0.001).</p> Conclusions <p>Within the limitation of this study, our results suggest the existence of a strong correlation between the two different registration protocols for the registration of the number of SB events.</p> Clinical relevance <p>The present study suggest that clinicians can adopt easier and user-friendly protocols for the registration of sleep bruxism events, that do not necessarily require a pre-calibration of the device.</p>
