The unilateral masseteric EMG was recorded during clenching tasks at 10 levels of force up to maximum voluntary clenching (MVC) twice on separate days (Day 1, Day 2). BF was simultaneously measured using a pressure\u2010sensitive occlusal film. The regression equation between the BF and EMG amplitude was calculated on Day 1. Estimated BF on Day 2 was calculated using information on the EMG amplitude on Day 2 (EMG\u2010amp), Day 1 BF at the MVC, and Day 1 regression equation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Actual value of BF showed a small correlation coefficient with EMG\u2010amp, whereas strong correlations were observed with the estimated values additionally using information of Day 1 BF at the MVC.
