Introduction: Temporomandibular Disorder (TMD) is a painful orofacial disorder that includes pain in the temporomandibular joint area, muscular weakness (especially masticatory muscles), mandibular movement limitation and joint clicks. Etiology of TMD is multifactorial and can be the result of psychological stress, occlusal interferences, inappropriate tooth position, dysfunction of masticatory muscle and adjacent structures, or a combination of all these factors. It is aimed to investigate relationships between anxiety, as a risk factor, and TMD.
Materials and Methods: This cross-sectional study was conducted in summer and fall of 2017 on 100 law students of Islamic Azad University of Bandar-e- Anzali, Iran. In order to investigate signs, symptoms and severity of TMD, the Fonseca questionnaire and for assessing apparent and hidden anxiety, Spielberger questionnaire were used.
Results: The mean scores of hidden and apparent anxiety were 46.37 and 47.30. According to Fonseca questionnaire, most of the people were mildly disturbed by disorder (43%). There was no significant relationship between apparent anxiety and TMD (p <0.646) and There was a positive and significant relationship between hidden anxiety and TMD (p <0.012). The mean score of severity of temporomandibular disorder was 36.12 and most of the people were mildly disturbed by it (43%). According to the Fonseca questionnaire there was a positive and significant relationship between hidden anxiety and TMD (p <0.012).
Conclusion: People with higher hidden anxiety experienced more TMD problems so it's better for most patients with TMJ problems to reduce their mental stress apart from dental treatments, otherwise dental treatment will not be sufficiently effective.
