 <translate>In order to achieve a complete clinical evaluation of mastication, an in-depth neurophysiopathological assessment of masticatory muscles control is required. Electromyography technique (EMG) is widely used for this purpose, but failed to provide convincing results</translate>.
 <translate>The aim of this work was to describe our quantitative objectivation of the motor control of the masticatory muscles and to verify the hypothesis to consider the bilateral Root Motor Evoked Potentials as an electrophysiological normalization factor</translate>.

An Artificial Neural Network computational model was used to estimate the correlation coefficient with the EMG values of each of both sides to predict the values from the right side by inputting values from the left side</translate>.

-| '''Results:'''<br />With regard to the descriptive statistical aspect the mean and SD values were for onset latency (1.96 msec ± 0.18 msec vs''.'' 2.01 msec ± 0.21 msec), amplitude (5.76 mV ± 2.01 mV vs''.'' 5.89 mV ± 2.51 mV) and integral area (11.09 mV/msec ± 4.45 mV/msec vs''.'' 11.27 mV/msec ± 4.34 mV/msec) for right and left masseter muscle, respectively. The Kruskal-Wallis test shows not statistically significant difference between the medians (confidence level 95%) in fact the ''P''–value was 0.33, 0.96 and 0.86 between sides for latency, amplitude and the EMG integral area, respectively for the bR-MEPs. The similarity between sides of the data sampled, studied in terms of mean squared error and correlation coefficients for latency (R2=0.955, SME=0,032) amplitude (R2=0.948, SME=0.162) and integrated area (R2=0.947, SME=0.212), indicates an organic symmetry of the trigeminal motor nervous system.

-| '''Conclusion:'''<br />These results show the high efficiency in terms of symmetry and stability of the bR-MEPs as a normalization factor.
