Cytocinic profile of synovial fluid in functional pathology of the temporomandibular joint under conditions of general vibration on Naval ships: clinical and pathophysiological examination

INTRODUCTION. One of the ecopathogenic factors of military labor for the crew of the electromechanical warhead of the ship is the general vibration. Its regular exposure can lead to the formation and progression of diseases of the temporomandibular joint. Laboratory examination of the composition and properties of synovial fluid fully characterizes the pathological processes occurring in the joint. Establishing the relationship between exposure to the influence of general vibration and pathologies of the temporomandibular joint will allow the development of preventive and rehabilitation measures for military personnel whose service is associated with regular exposure to general vibration.

OBJECTIVE. To determine the cytological profile of synovial fluid and the severity of temporomandibular joint disease depending on exposure to general vibration in Navy seafarers.

MATERIALS AND METHODS. A multi-level clinical and pathophysiological examination of Navy servicemen with varying exposure to general vibration was conducted. Clinical manifestations of masticatory apparatus pathology in seafarers were assessed, and a pathophysiological study of synovial fluid was conducted in servicemen with signs of TMJ damage.

RESULTS. It was found that servicemen from the electromechanical combat unit of the ship (the main group), who are constantly exposed to general vibration, more often have masticatory apparatus pathology in a moderate to severe form. As a result of the analysis of laboratory data of the TMJ synovial fluid, an increase in proinflammatory cytokines was revealed in the main group, as well as a decrease in the content of hyaluronic acid.

DISCUSSION. In military personnel more exposed to general vibration, TMJ pathology is more often detected, occurring in a moderate-severe form.

CONCLUSION. The advisability of paying more attention to the problem of the influence of general vibration on the development and progression of TMJ pathology in Navy servicemen has been proven.
