RESUMO
OBJECTIVES: The aim of this study was to summarize and systematically review the literature on the prevalence of different research diagnostic criteria for temporomandibular disorders (RDC/TMD) version 1.0 axis I diagnoses in patient and in the general populations. STUDY DESIGN: For each of the relevant papers, the following data/information were recorded for meta-analysis and discussion: sample size and demographic features (mean age, female-to-male ratio); prevalence of the assigned diagnoses; prevalence of the diagnoses assigned to the left and right joints, if available; prevalence of the diagnoses assigned to the 2 genders, if available; prevalence of the different combinations of multiple diagnoses, if available; and prevalence of TMD (only for community studies). RESULTS: Twenty-one (n = 21) papers were included in the review (15 dealing with TMD patient populations and 6 with community samples). The studies on TMD patients accounted for a total of 3,463 subjects (mean age 30.2-39.4 years, female-to-male ratio 3.3), with overall prevalences of 45.3% for group I muscle disorder diagnoses, 41.1% for group II disc displacements, and 30.1% for group III joint disorders. Studies on general populations accounted for a total of 2,491 subjects, with an overall 9.7% prevalence for group I, 11.4% for group IIa, and 2.6% for group IIIa diagnoses. CONCLUSIONS: Prevalence reports were highly variable across studies. Myofascial pain with or without mouth opening limitation was the commonest diagnosis in TMD patient populations, and disc displacement with reduction was the commonest diagnosis in community samples.

BACKGROUND: Job strain has been linked to increased risk of cardiovascular diseases. In modern media work, time pressures, rapidly changing situations, computer work and irregular working hours are common. Heart rate variability (HRV) has been widely used to monitor sympathovagal balance. Autonomic imbalance may play an additive role in the development of cardiovascular diseases. AIMS: To study the effects of work demands and job control on the autonomic nervous system recovery among the media personnel. METHODS: From the cross-sectional postal survey of the employees in Finnish Broadcasting Company (n = 874), three age cohorts (n = 132) were randomly selected for an analysis of HRV in 24 h electrocardiography recordings. RESULTS: In the middle-aged group, those who experienced high job control had significantly better vagal recovery than those with low or moderate control (P < 0.01). Among young and ageing employees, job control did not associate with autonomic recovery. CONCLUSIONS: High job control over work rather than low demands seemed to enhance autonomic recovery in middle-aged media workers. This was independent of poor health habits such as smoking, physical inactivity or alcohol consumption.

A standardized questionnaire was mailed to all employees of the Finnish Broadcasting Company with irregular shift work (n = 750) and to an equal number of randomly selected controls in the same company with regular 8-h daytime work. The questionnaire covered demographic items, employment details, general health experience, physical status, psychosocial status, stress, work satisfaction and performance, tobacco use, bruxism, and restless legs symptoms (RLS). The aim was to investigate among a multiprofessional media personnel the associations between reported bruxism and RLS, while simultaneously controlling the effects of gender, age, tobacco use, shift work, and dissatisfaction with current workshift schedule. 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). In the bivariate analyses, RLS was more prevalent in workers at either end of the studied age range (p < 0.05). Self-reported frequent bruxism was significantly associated with younger age (p < 0.05). Females reported RLS (11.4%) slightly more often than males (7.7%) (NS). In logistic regression, frequent bruxism (p < 0.05) and older age (p < 0.05) were significantly positively associated with RLS. Dissatisfaction with one's current workshift schedule (p < 0.05) and RLS (p < 0.05) were significantly positively associated with frequent bruxism, while age (p < 0.05) was significantly negatively associated. In conclusion, perceived bruxism may be a sign of a stressful situation or dissatisfaction, while RLS as a more stable trait may in itself negatively affect sleep quality and further enhance the problem.
