TEMPOROMANDIBULAR DISORDERS AND PSYCHOLOGICAL FACTORS: A LITERATURE REVIEW

ABSTRACT.

Temporomandibular disorders (TMD) are biological conditions that involve signs and symptoms, such as chronic pain in the temporomandibular joint and mastication muscles. This study aimed to identify which and how psychological concepts are described in articles on dental interventions related to TMD, in systematic review articles. For this, three databases were used in the search and selection: PubMed, Scopus and Web of Science. The same set of key words was applied to all these databases. Review articles published between 2000 and 2017, written in English, were selected. Of the 4,092 articles found, seven were selected describing psychological interventions related to TMD. All selected articles were analyzed based on their objectives and discussions, considering the presentation and understanding of psychological variables related to temporomandibular disorder and the interventions used. Qualitative and quantitative analyses were carried out. It can be concluded that the understanding and definition of psychological variables related to TMD are not evident, which makes it difficult to produce clear results on the effectiveness of diagnoses and interventions for TMD.
