A New Short-Term Assessment Condition for Evaluating Nonfunctional Electromyographic Activity of Masseter Muscle During Wakefulness.

Background: Awake bruxism involves masticatory muscle activity during wakefulness, potentially leading to clinical concerns. Accurate electromyography (EMG) assessment is challenging with brief durations.

Objective: To establish a reliable, short-term measure for nonfunctional masseter muscle activity during wakefulness.
