“…Figure 4 demonstrates no significant difference in the EMG activity between the Q-SB group and the Q-control group classified by the questionnaire, suggesting that evaluation of SB only by a questionnaire was not linked to the actual EMG activity during sleep. It has also been reported that the portable automatic sleep bruxism analysis is considered to be a moderately accurate screening method for sleep bruxism, in spite of the defects that it cannot discriminate tooth grinding from clenching and tends to overestimate the presence of bruxism events [17,[27][28][29]. The signal recognition algorithm of the ambulatory EMG device utilized could help to exclude events unrelated to SB (e.g., grimacing).…”

“…The wireless design and small number of components may have contributed to this perception. Moreover, compared with other ambulatory EMG devices (eg), a set‐up procedure for defining thresholds of maximum voluntary contraction (MVC) is not required. This is necessary if scoring of EMG events is based on a % MVC method, which is not the case for BUTLER ® GrindCare ® .…”

Background: It is important to know how easy or difficult it is to use an ambulatory electromyographic (EMG) device for sleep bruxism assessment, and how this might affect its future utilisation. Objective:To explore the experience of individuals using an EMG device that pairs with a smartphone app, in order to detect factors that could facilitate and/or hamper its utilisation in future scientific research. Methods: Fifteen adults were recruited in the Orofacial Pain and Dysfunction Clinic of the Academic Centre for Dentistry Amsterdam (ACTA). Overnight recordings were performed in the home setting during one week. Time investment, feelings and thoughts, encountered difficulties and reasons for not using the device were assessed in a diary through open-ended questions and 5-point Likert scales. Content analysis of textual data was performed, and descriptives of quantitative data were calculated.Results: Time investment was low (mean 10.2 minutes in the clinic, and 1.9 minutes per recording at home). Quantitative data showed an overall good experience (median of 4). Qualitative diary data showed that the desire to gain insight into one's masticatory muscle activity formed the main motivation to use the device. Device detachment and difficulty in using the app were the most prominent negative experiences. Conclusion:The EMG device was well accepted for multiple overnight recordings.Curiosity for gaining insight into muscle activity was the most important factor that facilitated its use, and the app addressed this need. Device detachment and difficulties in using the app were the main factors that hampered its use. K E Y W O R D Sambulatory, electromyography, experience, mixed methods, sleep bruxism, smartphone

“…This observational prospective study, involved 53 subjects (27 m, 25 f, 28 ± 13 years) selected among patients referring to the Orthodontics Unit of the Dental School of the University of Torino in the period February-December 2015 requiring an orthodontic treatment. All the subjects were screened for sleep bruxism with a validated portable device (Bruxoff ®, OT Bioelettronica, Torino, Italy) (20)(21)(22)(23)(24). On the basis of this evaluation the subjects were divided into two groups: the case group composed by 20 patients (7 m, 13 f, 25 ± 10 years), and the control group composed by 33 patients (20 m, 13 f, 26 ± 10 years).…”

Background: In the last years an increasing number of patients have sought for comfortable and aesthetic alternatives to fixed appliances. Aligners, due to the protection against tooth wear, can be compared to occlusal splints used in patients suffering from sleep bruxism (SB). The aim of the study was to analyze the effects of clear aligners on SB episodes using a validated portable device (Bruxoff®, OTBioelettronica, Torino, Italy) allowing a simultaneous recording of electromyographic signals from both the masseter muscles as well as heart frequency to evaluate variation on SB activity. Methods: Forty patients were analyzed for the study. Twenty of them were assigned to orthodontic treatment with clear aligners (Invisalign®, Align Technology). The other twenty patients were used as control group observed for a period of twelve months. Intra-group and inter-group variances were analyzed by using a two-way ANOVA test. For each analysis a P < 0.05 was set. Results: After the first month of clear aligners therapy, all patients in the case group showed a significant reduction in the number of SB episodes (P < 0.05). However, after three months SB values returned to baseline levels. The number of tonic contractions were reduced even after three months of orthodontic treatment (P < 0.05). Conclusions: While clear aligners seem to be capable to reduce clenching, i.e. occlusal load, in SB patients, the grinding activity seems to be not influenced by those appliances at least in the short term of the present investigation.
