    The present study was performed on media personnel who could be considered to be under sustained pressure at work due to intense on-going technological, organizational and economic changes. The study formed part of a comprehensive investigation of shift work and its sleep/awake consequences. The general aim was to examine the relationships of self-reported bruxism and sleep quality among employees with or without irregular shift work. The study also focused on the possible associations of bruxism and orofacial pain. Some psychological, neurological and physiological factors known to be detrimental to sleep were also studied. A questionnaire with several standard questions was mailed to all employees of the Finnish Broadcasting Company with irregular shift work (n=750; 57.0 % men) and to an equal number of randomly selected controls in the same company with regular eight-hour daytime work (42.4 % men). The mean age of invited subjects was 43.0 (SD 10.4) years in irregular shift work and 44.8 (SD 10.2) years in day work. The work duties of the present media personnel included journalism, broadcasting, programme production, technical support and administration. The questionnaire covered perceived bruxism (assessed with a five-point scale) and, among others, the following: demographic items, employment details, general health experience, physical status, pain symptoms, psychosomatic symptoms, psychosocial status, stress experience, work satisfaction and performance, perceptions of sleep and its awake consequences. The overall response rate was 58.3% (53.7% men). The response rate in the irregular shift work group was 82.3% (56.6% men) and in the regular daytime work group 34.3% (46.7% men). The invited subjects and respondents in both shift work and day work groups were similar as regards gender and age (NS). Frequent self-reported bruxism was found among 10.6 % of subjects overall. The bruxism scores were evenly distributed in the irregular shift work and regular day work groups (NS). Similarly, a total of 43.6 % reported disrupted sleep and 36.2 % perceived their as sleep non-restorative. Current orofacial pain was found overall in 19.6 % of the study population. Among those reporting current pain 88.3 % had experienced it for over six months. According to the multivariate analyses, self-reported bruxism and dissatisfaction with current work shift schedule were significantly associated with most studied sleep variables. More frequent bruxism (p<0.01) and more severe stress (p<0.001) tended to occur more often among those subjects dissatisfied with their work shift schedule. It was found that dissatisfaction with one’s work shift schedule and not merely irregular shift work may aggravate stress and bruxism. In addition, frequent self-reported bruxism was associated with increased numbers of health care visits. The results also revealed significant associations between self-reports of bruxism and anxiety, and bruxism and orofacial pain experience. Based on the multivariate analyses, it can be concluded that disrupted sleep and bruxism may be concomitantly involved in the development of orofacial pain. It may also be possible that self-reported bruxism indicates sleep problems and their adherent awake consequences in non-patient populations. It was suggested that subjectively conceptualized awareness of bruxism may be linked to stress-related states and behavior which could be useful knowledge for health care professionals.
