Features of the results of electromyography of muscles of the maxillofacial region and psychological examination in persons of stressed professions

A dental examination of people with stressful professions reveals hypertonicity of the masticatory muscles, but this relationship has not been sufficiently studied in workers in hazardous industries. Objective — to study the dependence of the electromyography data of the muscles of the maxillofacial region in workers of radiation-hazardous industries on their psychological characteristics. Materials and methods. A comparative analysis of the electromyography of the masticatory and temporal muscles, the “Hamburg testing” of the masticatory apparatus and psychological characteristics was carried out in 50 workers of hazardous industries with a long experience (radiation production factor) and 53 working in normal working conditions. Results. Differences were found between the results of a psychophysiological examination, a “Hamburg test” of the chewing apparatus and electromyography of the muscles of the maxillofacial region in workers with dangerous working conditions and working under ordinary conditions. Workers in hazardous industries, according to a psychological examination, are subject to chronic stress, which leads to a distortion of the muscle tone of the maxillofacial region, which, in turn, leads to more frequent detection of masticatory apparatus dysfunction among workers. Conclusion. The results of the study must be taken into account during complex dental rehabilitation of workers in hazardous industries, including measures aimed at normalizing muscle tonus in the maxillofacial region.
