Purpose: To investigate the masticatory function of patients with different temporomandibular disorders (TMD) phenotypes, and to explore the risk factors for the masticatory function of TMD patients among multiple biopsychosocial variables using patient-reported outcomes (PROs). Methods:Clinical features and TMD diagnoses of 250 cases were investigated by reviewing medical records. Psychosocial factors were evaluated using four questionnaires representing pain severity and pain interference (Brief Pain Inventory), pain catastrophizing (Pain Catastrophizing Scale, PCS), psychological distress (Symptom Check List-90-Revised, SCL-90R) and kinesiophobia (Tampa Scale for Kinesiophobia for Temporomandibular Disorders, TSK-TMD). Masticatory function, as a dependent variable, was determined using the Jaw Functional Limitation Scale (JFLS). Kruskal-Wallis test and Spearman's rank correlation were used for analyses. Results:A total of 145 cases were included and classified into four subgroups including group 1: TMD with internal derangement without pain (n=14), group 2: TMD with muscle pain (n=32), group 3: TMD with joint pain (n=60) and group 4: TMD with muscle-joint combined pain (n=39). Pain severity (p=0.001) and interference (p=0.022) were the highest in group 2, but the mean global score of JFLS was the highest in group 3, followed by group 4, group 2, and group 1 (p=0.013). Pain severity, pain interference, the mean global score of PCS and the mean global score of TSK-TMD showed significant and moderate correlation with the mean global score of JFLS. All subdimensions and the global severity index of SCL-90R had significant, but weak correlations with all scores of JFLS. Conclusions:The results suggest that masticatory functional limitation depends on the TMD phenotypes. Among the various PROs, pain perception, pain catastrophizing and kinesiophobia seem to be more influential risk factors on jaw function than psychological distress, such as depression and anxiety.

“…In addition, Gil-Martínez et al [46] showed the same result that no differences of kinesiophobia were found between muscle, joint and combined groups.…”

“…Kinesiophobia was emphasized in recent studies as a new rising predictor of pain and disability in TMD patients [27,40,46,48]. Gil-Martínez et al [46] suggested that kinesiophobia should be included in the psychosocial evaluation and treatment of TMD patients. Since Visscher et al…”

Risk Factors of the Masticatory Function in Patients with Temporomandibular Disorders: A Cross-Sectional Cohort Study

Park

“…Findings of Bortsov et al suggest that subjects with prevailing sympathetic tone are more likely to express more somatic symptoms, namely higher pain intensity or unpleasantness, poor sleep quality; concluding that further studies should focus on whether an individual autonomic profile could be a prognostic factor for TMD progression and treatment outcomes (Bortsov et al, ). Study of Gil‐Martínez provides important information regarding psychosocial factors that appear in patients with chronic TMD, which could be disability predictors (Gil‐Martínez, Grande‐Alonso, López‐de‐Uralde‐Villanueva, López‐López, & Fernández‐Carnero, ). The author suggests that these factors should be considered as likely predictors in the evaluation and treatment of these patients.…”

Is there a relationship between psychological factors and TMD?

et al. 2019

Introduction Medical 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 Methods A 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. Results About 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. Conclusion There 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.

“…Recent studies support that kinesiophobia is a predictor of disability and craniofacial pain in patients with TMD [7, 8]. Thus, it has important clinical significance of evaluating and treating of TMD patients [7]. Therefore, there is a need to yield an appropriate tool for the evaluation of fear of movement in these patients.…”

BackgroundThe aim of the study was to validation of the Tampa Scale for Kinesiophobia for Temporomandibular Disorders (TSK-TMD) for use in patients with painful TMD.MethodsThe original TSK-TMD was translated and cross-culturally adaptated following international guidelines. A total of 160 patients with temporomandibular disorders (TMD) were enrolled to fill out the scale. The internal consistency and test-retest methods were used to evaluate the reliability of the TSK-TMD. The validity of the TSK-TMD was analyzed by content validity, construct validity and convergent validity. Construct validity was assessed based on exploratory factor analysis (EFA), and convergent validity by examining the correlation between the global rating of oral health question and TSK-TMD scores.ResultsCronbach’s alpha value for the total TSK-TMD score was 0.919 and the intraclass correlation coefficient (ICC) value for the TSK-TMD was 0.797. Construct validity was assessed by EFA, extracting two factors, accounting for 71.9% of the variance. The factor loadings of all items were higher than 0.40. In terms of convergent validity, the TSK-TMD subscales showed good correlations to the global rating of oral health question.ConclusionThese findings show that the Chinese version of TSK-TMD has satisfactory psychometric properties and is appropriate for use in patients with painful TMD in China.
