Errors in stomatological endodontic interventions can result in undesirable contacts of an endohermetic with the inferior alveolar (mandibular) nerve leading to the development of compressive/toxic neuropathy. In a group of 43 patients, we examined characteristics of EMG responses evoked by electrical stimulation of the above nerve (applied in the region of the mental opening) and recorded from mm. mentalis and orbicularis oris. These responses are interpreted as reflex reactions to activation of afferent fibers of a branch of the n. trigeminus, transmission of the activity to the nucl. n. facialis. and coming of efferent activity to the muscles via a branch of the latter nerve. In patients with neuropathic changes, the latencies of the analyzed EMG response were significantly longer than those in the control group, while the mean amplitude of such reactions was noticeably lower. Complex pathogenetic treatment provided certain normalization of the above-mentioned indices, and positive changes were greater in those patients who began clinical treatment at earlier stages of the development of neuropathy.
