Abstract
Background: Temporomandibular disorders (TMD) aetiological factors have multidimensional, biomechanical, neuromuscular, biopsychosocial and neurobiological aspects. The relationship between work environment factors or occupational stress and TMD is not sufficiently investigated and is still poorly understood.
Objective: To investigate work-related stress and the effect of personal computer (PC) use on TMD.
Methods: A questionnaire-based survey that was conducted among 5619 employees of three companies. The questionnaire was used to screen TMD-related symptoms (TRS), habitual behaviours, psychosocial status, awake and sleep bruxism and time spent using a PC at work. After excluding missing data values, 4776 individuals were included in the analysis. Structural equation modelling (SEM) was used to test the hypothesised models that correlated TRS with the other factors of the questionnaire, and to examine the effect of the time spent using the PC on men and women in our sample. Statistical significance was set at p < 0.05.
Results: SEM revealed that psychosocial factors affected TRS indirectly through their direct effect on sleep bruxism and other behavioural factors which had a direct effect on TRS. The effect of PC usage time was greater for women than for men.
Conclusions: Behavioural factors, including SB, may have a direct effect on TRS, while psychosocial factors may have an indirect effect on TRS. In addition, the results suggest that prolonged PC use influences behavioural and psychosocial factors, and this was especially true for women.
期刊介绍：
Journal of Oral Rehabilitation aims to be the most prestigious journal of dental research within all aspects of oral rehabilitation and applied oral physiology. It covers all diagnostic and clinical management aspects necessary to re-establish a subjective and objective harmonious oral function.
Oral rehabilitation may become necessary as a result of developmental or acquired disturbances in the orofacial region, orofacial traumas, or a variety of dental and oral diseases (primarily dental caries and periodontal diseases) and orofacial pain conditions. As such, oral rehabilitation in the twenty-first century is a matter of skilful diagnosis and minimal, appropriate intervention, the nature of which is intimately linked to a profound knowledge of oral physiology, oral biology, and dental and oral pathology.
The scientific content of the journal therefore strives to reflect the best of evidence-based clinical dentistry. Modern clinical management should be based on solid scientific evidence gathered about diagnostic procedures and the properties and efficacy of the chosen intervention (e.g. material science, biological, toxicological, pharmacological or psychological aspects). The content of the journal also reflects documentation of the possible side-effects of rehabilitation, and includes prognostic perspectives of the treatment modalities chosen.
