Substantially, from this overview of the database research it is clear that if on the one hand bruxism is a complex phenomenon on the other the efforts have concentrated almost exclusively on occlusal and dental factors in general, leaving out one aspect, essential in our opinion, that of functionality of the trigeminal nervous system. | Substantially, from this overview of the database research it is clear that if on the one hand bruxism is a complex phenomenon on the other the efforts have concentrated almost exclusively on occlusal and dental factors in general, leaving out one aspect, essential in our opinion, that of functionality of the trigeminal nervous system. | ||

A synthetic extraction of the contents of the article by Jessica M D'Amico et al.,<ref name=":12" />, shows evidence that the discharge of neurons in the raphe nuclei, in the locus coeruleus, in the subcoeruleus and in A5/A7 cells, releases serotonin and norepinephrine and facilitates PIC (persistent internal ionic currents referred to as 'PIC') to the trigeminal motor neuron pool. These episodes increase during micro-awakenings (Leung and Mason 1999,<ref>{{cita libro | A synthetic extraction of the contents of the article by Jessica M D'Amico et al.,<ref name=":12" />, shows evidence that the discharge of neurons in the raphe nuclei, in the locus coeruleus, in the subcoeruleus and in A5/A7 cells, releases serotonin and norepinephrine and facilitates PIC (persistent internal ionic currents referred to as 'PIC') to the trigeminal motor neuron pool.

==Conclusion== | ==Neurophysiological Conclusion== | ||
The conclusion, unfortunately, remains the same and that is that the external manifestation of an organic and/or functional disturbance is a macroscopic effect which transfers a series of mesoscopic abnormalities of the system over time. Here we were able to test only some of these neurobiological mesoscopic phenomena but the clinical result must be interpreted as a whole phenomenon because current scientific knowledge does not allow us to weigh the physiopathological value of the neurotransmitters, the PIC, the basal nuclei, the ascending reticular formation, etc. . What is certain is that an abnormality in one of these sites can generate an 'encrypted code' as a message in machine language of the Central Nervous System which in itself could not be 'Bruxism' but a form of 'Neuromotor Hyperexcitability'. | The conclusion, unfortunately, remains the same and that is that the external manifestation of an organic and/or functional disturbance is a macroscopic effect which transfers a series of mesoscopic abnormalities of the system over time.
