Popis: Objective: To evaluate the activity of mentalis (MN), buccinator (BC), and suprahyoid (SH) muscles among participants with different lip competence..Methods: Sixty-three participants were classified clinically and assigned to the following groups of 21 each: 1) competent lips (competent), 2) incompetent lips (incompetent), or 3) forced lip closure (forced). Activity was recorded at rest, swallowing, speaking, reciprocal compression of the lips, and chewing.Results: MN activity in incompetent was significantly higher than competent at rest, and it was significantly higher in incompetent and forced when compared with competent during swallowing (p .05). During speaking, reciprocal compression of the lips, and chewing, MN activity did not show significant differences among groups. BC and SH activity did not show significant differences (p> .05).Conclusion: MN activity during swallowing can be considered a relevant biomarker to differentiate between forced and competent participants.
