Behavioral Interventions for Controlling Oral Behaviors

Ecological momentary assessment (EMA) interventions via mobile devices can be implemented to monitor an individual's negative health behaviors in real-time, increase awareness, and assist patients in overting those behaviors. In recent years, EMA interventions have been used to improve patients' awareness of specific oral behaviors, such as tooth clenching or awake bruxism, which can produce excessive forces on the muscles of mastication and lead to or exacerbate symptoms of temporomandibular disorders (TMD). Yet, whether EMA interventions are effective in reducing oral behaviors and masticatory muscle activity in the short- and long-term, or whether they are more effective than patient education remains unclear. In this randomized clinical trial, we aim to test the effects of a 1-week EMA intervention combined with structured information on masticatory muscle activity and determine whether a combined approach including an EMA intervention and structured information is more effective in reducing masticatory muscle activity than structured information alone. Our study will have a significant impact on orofacial pain clinical research as it will provide clinically relevant measures which could inform multimodal approaches for the management of painful TMD.
