Objective:
This study investigated the correlation between oral behaviors measured by the Oral Behaviors Checklist (OBC) and the frequency of awake bruxism (AB), assessed by Ecological Momentary Assessment (EMA).
Methods:
Seventy-five individuals with AB completed the OBC and responded to ten daily mobile prompts that assessed real-time jaw muscle behavior for a week.
Results:
Non-functional OBC scores correlated positively with overall AB (r = 0.384, p < .001) and individual AB-behavior frequencies measured by EMA, except for a negative correlation with teeth contact (r = -0.289, p = .012).
Conclusion:
Functional OBC scores were not associated with AB frequencies. The OBC may serve as a preliminary screening instrument in identifying AB-related behaviors.
