Comparison between mean maximum mouth-opening amplitudes, left and right lateral movements and animal body weight (in millimetres and kilograms, respectively). For the variable weight the sample size of group E90 was n = 4. Variables are expressed as mean ± standard deviation. Within-group comparisons were performed through repeated-measures analysis of variance (at 3 different moments) or paired-sample T-tests (weight). Letters (A, B) represent significant statistical differences
