Psychological Distress and Emotional Pain Among Adult Attendees of a Dental Clinic: A Case-Control Study

Prevalence of self-reported pain-related temporomandibular disorders and association with psychological distress in a dental clinic setting

Objectives

To investigate the prevalence of self-reported pain-related temporomandibular disorders (TMDs) and its association with psychological status in a dental clinic setting.

Methods

In this cross-sectional study, patients were asked to complete a TMD pain screener and the Patient Health Questionnaire-4 (PHQ-4). Correlations between symptoms of pain-related TMDs and PHQ-4 scores were analysed using Spearman’s correlation test. Symptoms of pain-related TMDs were compared between four groups of participants with different psychological profiles using the Kruskal–Wallis test followed by multiple comparisons. The level of significance was adjusted using the Dunn–Bonferroni test.

Results

The prevalence of self-reported pain-related TMDs was 22.2%. TMD pain score was positively correlated with PHQ-4 score. The high anxiety and the comorbidity groups had significantly higher TMD pain scores than the controls.

Conclusion

There was a high prevalence of self-reported pain-related TMDs, which was correlated with scores on all psychological assessment scales. Symptoms of pain-related TMDs were significantly greater in patients with high anxiety scores, regardless of depression level.

Does psychache mediate the relationship between general distress and suicide ideation?

This study evaluated whether psychache (i.e., mental pain) mediates the association between general distress, assessed as the frequency and the intensity of psychological symptoms in the previous week, and suicide ideation in community adults. For a sample of 202 adults, psychache fully mediated the relationship between suicide ideation and the frequency of psychological symptoms, and partially mediated the relationship between suicide ideation and the intensity of psychological symptoms. As such, mental pain fully or partially explains the process linking the frequency and the intensity of general distress to suicide ideation and, thus, mental pain is a target for potential intervention.
