Relation between stress and symptoms of craniomandibular disorders in adolescents


Sieber, M; Grubenmann, E; Ruggia, G M; Palla, S (2003). Relation between stress and symptoms of craniomandibular disorders in adolescents. Schweizer Monatsschrift für Zahnmedizin SMfZ, 113(6):648-654.

Abstract

The psychophysiologic theory proposes that stress can precipitate craniomandibular disorders (CMD) and that stress correlates more strongly to disorders of the masticatory muscles than to temporomandibular joint disorders. Empirical reports show only low correlations between emotional stress and CMD signs and symptoms, and that some of them might be spurious. In the present study this correlation was assessed in 417 adolescents from 11 to 16 years old. Data from the clinical examination were used to construct two indices: 1) The number of muscles sites tender to palpation, and 2) signs from the joint and restricted movement. Results show that global stress was only significantly correlated with the muscle index (r = .20), but not with the other index. Only the multiple regression analyses regarding muscle disorders had a significant beta weight of global stress that remained significant when controlling for the intervening variables age, gender and psychosomatic symptoms. The pattern of the stress-specific and unspecific CMD signs was consistent with the postulated stress model. Since there are positive results with regard to the stress model in patient samples and in this unselected sample of adolescents, further research is indicated, including the concept of somatization more explicitly.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
