Winck Medicina Masseter EMG Sleep bruxism Obstructive sleep apnea syndrome Sleep bruxism (SB) and obstructive sleep apnoea syndrome (OSAS) share common pathophysiologic pathways. We aimed to study the presence and relationship of SB in a OSAS population. Patients referred with OSAS suspicion and concomitant SB complains were evaluated using a specic questionnaire, orofacial evaluation and cardio-respiratory polygraphy that could also monitor audio and EMG of the masseter muscles. From 11 patients studied 9 had OSAS. 55.6% were male, mean age was 46.3 ± 11.3 years, and apnea hypopnea index of 11.1 ± 5.7/h. Through specic questionnaire 55.6% had SB criteria. Orofacial examination (only feasible in 3) conrmed tooth wear in all. 77.8% had polygraphic SB criteria (SB index > 2/h). Mean SB index was 5.12 ± 3.6/h, phasic events predominated (72.7%). Concerning tooth grinding episodes, we found a mean of 10.7 ± 9.2 per night. All OSAS patients except two (77.8%) had more than two audible tooth-grinding episodes. These two patients were the ones with the lowest SB index (1.0 and 1.4 per hour). Only in one patient could we not detect tooth grinding episodes. There was a statistically signicant positive correlation between tooth grinding episodes and SB index and phasic event index ( R = 0.755, p = 0.019 and R = 0.737, p = 0.023 respectively, Pearson correlation). Mean apnoea to bruxism index was 0.4/h, meaning that only a minority of SB events were not secondary to OSAS. We could not nd any signicant correlation between AHI and bruxism index or phasic bruxism index ( R = 0.632 and R = 0.611, p > 0.05, Pearson correlation). 2017 artículo científico 0873-2159 https://www.redalyc.org/articulo.oa?id=169749568005 en http://www.redalyc.org/revista.oa?id=1697 Revista Portuguesa de Pneumología application/pdf Sociedade Portuguesa de Pneumologia Revista Portuguesa de Pneumología (Portugal) Num.1 Vol.23 |
