Few studies have attempted to characterize the Orofacial pain (OP) associated with bruxism (i.e., to examine the neurobiological and physiological characteristics of the mandibular muscles). Some clinical cases and small-scale studies suggest that certain drugs linked to the dopaminergic, serotoninergic, and adrenergic systems can either suppress or exacerbate bruxism. Further, the majority of these pharmacological studies indicate that various classes of drugs can influence the muscular activity related to bruxism, without exerting any effect on OP. Therefore, the sensitization of the trigeminal nociceptive system and the facilitating effect on mandibular stretch reflexes and neural hyperexcitability are neurophysiopathogenetic phenomena that can be correlated to pain in the craniofacial region. However, up to now, no correlation has been reported between OP, dysfunction of the mesencephalic nuclei, and facilitation of trigeminal nociception, except for a clinical study on a patient affected by pontine cavernoma, which highlighted a relative facilitation of the trigeminal nociceptive system through the reflexes. | Few studies have attempted to characterize the Orofacial pain (OP) associated with bruxism (i.e., to examine the neurobiological and physiological characteristics of the mandibular muscles).
