[Relation between temporomandibular joint disorder and subjective symptoms of fatigue]

An investigation was performed for the purpose of guaging the relation between temporomandibular joint disorder on the one hand and occupational category and subjective symptoms of fatigue on the other. Subjects were 2,414 workers (1,598 male, 816 female) in small and medium size enterprises at 67 workplaces in Hiroshima Prefecture. A comparison of cases with and without temporomandibular joint disorder showed that there were more complaints of fatigue among those with the disorder. Given these indications that temporomandibular joint disorder was related to occupation, it is possible that temporomandibular joint disease may be a work-related disease.
