Reported bruxism and stress experience.
The aim of the study was to analyze whether perceived bruxism was associated with stress experience, age, gender, work role, and occupational health care use among a nonpatient multiprofessional population. Altogether, 1784 (age 30-55 years) employees of the Finnish Broadcasting Company were mailed a self-administered questionnaire covering demographics, perceived bruxism, total stress experience and the use of health care services provided by the company. The response rate was 75% (n = 1339, 51% men) and mean age was 46 years (SD = 6) in both genders. There were no significant differences in demographic status by age and gender. Bruxism and stress experiences did not significantly vary with regard to category of work, but both were significantly more frequent among women (P < 0.05). In all work categories frequent bruxers reported more stress, and the perceptions were significantly differently polarized between the groups (P < 0.001). According to logistic regression, frequent bruxism was significantly positively associated with severe stress experience (Odds ratio = 5.00; 95% CI = 2.84-8.82) and female gender (Odds ratio = 2.26; 95% CI = 1.43-3.55). Frequent bruxism was also significantly positively associated with the numbers of occupational health care and dental visits (P < 0.01), and slightly negatively associated with increasing age and work in administration (P < 0.05). It was concluded that bruxism may reveal ongoing stress in normal work life.
