Workers in stressful industries include workers with hazardous working conditions (HWC), in particular, with a radiation production factor. Clinical and X-ray dental examination of workers with OUT was carried out, Hamburg testing of the chewing apparatus, electromyography of the masticatory muscles, computer analysis of occlusion were carried out. Based on the identified need for treatment and prosthetics, the Concept for the Prevention and Treatment of Dental Diseases in Persons with Occupational Stressful Stress was developed, which includes comprehensive dental rehabilitation of workers using electromyographic, occlusive control during treatment, followed by dispensary control at least twice a year. After a year of implementation of the Concept, re-examination showed a significant decrease in the prevalence of non-carious lesions, gingivitis, secondary deformities of the dentition; detectability of teeth affected by caries, unsatisfactory oral hygiene, inadequate quality of fillings and endodontic treatment, as well as normalization of the tone and symmetry of the activity of the masticatory muscles, indicators of the Hamburg express test of the masticatory apparatus and indicators of computer analysis of occlusion.
