Comparative study of surface electromyography of masticatory muscles in patients with different types of bruxism

Figure 3 Comparison of the average duration (mean ± SD) of the chewing cycle. A: Comparison of the duration of the chewing cycle for free chewing of food; B: Comparison of the duration of the chewing cycle for unilateral chewing of candy; C: Comparison of the duration of the chewing cycle for unilateral chewing of almond; D: Free chewing candy process; E: Unilateral chewing candy process on the preferred side (PS); F: Unilateral chewing candy process on the non-preferred side (NPS); G: Free chewing almond process; H: Unilateral chewing almond process on the PS; I: Unilateral chewing almond process on the NPS. ^aComparison to the non-bruxism group, P < 0.05; ^bComparison to the centric bruxism group, P <0.05; ^cComparison of the duration of the first chewing cycle and the subsequent total 20 chewing cycles within each group, P < 0.05. CB: Centric bruxism; ECB: Eccentric bruxism; NB: Non-bruxism; CY: Chewing cycle.
