Wireless EMG recordings of daytime bruxism : Differentiating clenching from swallowing

Abstract

Bruxism is considered a potential etiologic factor for temporomandibular disorders. While the study and recording techniques for sleep bruxism have dramatically evolved during the last two decades, the validation of recording methods for daytime bruxism is still a challenge to researchers. One of the main difficulties remains the differentiation of clenching events from functional activities as well as the use of wired EMG systems. The present pilot study aimed to differentiate experimental diurnal clenching events from swallowing with a novel experimental setting using wireless technology.
