Is there a relationship between psychological factors and TMD?

Abstract

IntroductionMedical students are in a very demanding environment and are affected by high degree of stress. High levels of anxiety can affect a student's academic performance and also increase the risk of other health‐related problems. This study aims to evaluate, thanks to the intensity of stress manifestations (4DSQ) together with the sense of coherence (SOC), the prevalence of TMD and oral parafunctions in students enrolled in the University of Medical Sciences. Moreover, it aims to evaluate the relationship between the psychosocial manifestations of stress and sense of coherence in relation to gender.Materials and MethodsA total of 324 students of Poznań University of Medical Sciences participated in this study. Students were assessed using a three‐part questionnaire: one was to assess symptoms of TMD, the second part was 4DSQ, and the third was a SOC Questionnaire.ResultsAbout one‐third of the students in this study presented symptoms of TMD and perceived more intensively symptoms of distress, anxiety, somatization, and depression. They presented a higher level of somatic symptoms and a lower level of Sense of Coherence than students without TMD symptoms.ConclusionThere is a strong negative relationship between the sense of coherence and the level of perceived distress, anxiety, somatization, and depression. Female students attending Medical School showed a higher level of somatization of stress but with a higher capacity to overcome challenges as compared to men.
