Abstract

Abstract: Background: Studies on temporomandibular disorder (TMD) severity in patient populations are scarce. Objectives: This study sought to compare the psychological states and oral health–related quality of life (OHRQoL) among patients with differing TMD severity. Methods: Adult patients (≥18 years old) with and without (controls) TMDs were recruited from the TMD/oro‐facial pain centre and prosthodontics department, respectively. The presence and severity of TMDs were established with the Fonseca Anamnestic Index (FAI), and TMD diagnoses were confirmed with the Diagnostic Criteria for TMDs (DC/TMD). Psychological states and OHRQoL were examined with the Depression, Anxiety, Stress Scales‐21 (DASS‐21) and Oral Health Impact Profile for TMDs (OHIP‐TMD). Data were subjected to chi‐square, Kruskal‐Wallis/Mann‐Whitney U tests and Spearman's correlation ( α = .05). Results: A total of 961 participants with a mean age of 32.99 ± 13.14 years (71.19% women) were assessed. Frequencies of the various TMD categories were as follows: no TMD/controls (12.07%), mild TMD (24.56%), moderate TMD (40.37%) and severe TMD (23.00%). The three most common TMD‐related symptoms were TMJ noises, mouth opening difficulty and muscle pain. Participants with moderate/severe TMD presented a higher proportion of intra‐articular and/or combined disorders. They reported significantly higher levels of depression, anxiety, stress and poorer OHRQoL than their counterparts with no/mild TMD ( p < .001). Moderate‐to‐strong correlations were observed between FAI and DASS‐21/OHIP‐TMD scores (rs = 0.42–0.72). Conclusions: Patients with moderate/severe TMD had significantly higher levels of psychological disturbance and poorer OHRQoL. As OHRQoL and psychological states are correlated, psychological well‐being must be considered when managing patients with moderate/severe TMDs. Abstract : Moderate/severe TMD possibly had higher levels of psychological disturbance and poorer OHRQoL, psychological well‐being must be considered when managing patients with moderate/severe TMDs.
