ABSTRACT Objectives Methods Results Conclusion The relationship of somatisation with facial pain duration/intensity, pain‐related interference/disability and psychological distress was investigated in East Asian temporomandibular disorder (TMD) patients. Correlations between somatisation, facial pain and psychological characteristics were also explored alongside the demographic/physical factors associated with moderate‐to‐severe depression and anxiety.Anonymised data were acquired from records of consecutive ‘first‐time’ patients seeking TMD care at a tertiary oral medicine clinic. Axis I physical TMD diagnoses were established utilising the diagnostic criteria for TMDs (DC/TMD) protocol and patients with TMD pain were stratified into those with pain‐related (PT) and combined (CT) conditions. Axis II measures administered encompassed the Patient Health Questionnaire‐15 (PHQ‐15), Graded Chronic Pain Scale (GCPS), Patient Health Questionnaire‐9 (PHQ‐9) and General Anxiety Disorder Scale‐7 (GAD‐7). Individuals with PT and CT were further categorised into those without (Pain − Som/Comb − Som) and with somatisation (Pain + Som/Comb + Som). Statistical evaluations were performed with nonparametric and logistic regression analyses (α = 0.05).The final sample comprised 473 patients (mean age 36.2 ± 14.8 years; 68.9% women), of which 52.0% had concomitant somatisation. Significant differences in pain duration (Comb + Som > Pain − Som), pain‐related interference/disability (Comb + Som > Comb − Som) and depression/anxiety (Pain + Som, Comb + Som > Pain − Som, Comb − Som) were discerned. Depression/anxiety was moderately correlated with somatisation (rs = 0.64/0.52) but not facial pain characteristics. Multivariate modelling revealed that somatisation was significantly associated with the prospects of moderate‐to‐severe depression (OR 1.35) and anxiety (OR 1.24).Somatisation exhibited a strong association with psychological distress when contrasted with facial pain in East Asian TMD patients.

Objectives: This study investigated the jaw functional status and severity of somatic/psychological symptoms in different Diagnostic Criteria for temporomandibular disorders (DC/TMD) diagnostic subtypes and established the correlates between jaw functional limitation, somatization, depression and anxiety. Methods: Data were accrued from consecutive 'first‐visit' patients seeking TMD treatment at a university‐based oral medicine/diagnosis clinic. Axis I physical TMD diagnoses were derived using the DC/TMD methodology and patients were categorized into pain‐related (PT), intra‐articular (IT) and combined (CT) TMD groups. Axis II measures were also administered and included the Jaw Functional Limitation Scale‐20 (JFLS‐20), Patient Health Questionnaire‐15 and 9 (PHQ‐15 and PHQ‐9) and General Anxiety Disorder Scale‐7 (GAD‐7). Chi‐square/Kruskal–Wallis tests and Spearman's correlation were employed for statistical evaluations (α =.05). Results: The final dataset consisted of 772 TMD patients (mean age of 37.7 ± 15.9 years; 70.2% females). The prevalence of PT, IT and CT was 11.9%, 15.7% and 72.4%, respectively. Significant differences in functional jaw limitations, somatization, depression (CT, PT > IT) and anxiety (CT > PT, IT) were observed. Moderate‐to‐severe somatization, depression and anxiety were detected in 12.6%–15.7% of patients. For all three TMD groups, JFLS global scale/subscale scores were weakly associated with somatization, depression and anxiety scores (rs < 0.4). Moderate‐to‐strong correlations were noted between somatization, depression and anxiety (rs = 0.50–0.74). Conclusions: Functional jaw limitations were associated with painful TMDs but appear to be unrelated to somatization and psychological distress. Somatization and depression/anxiety were moderately correlated, underscoring the importance of somatic symptom screening when managing TMD patients. [ABSTRACT FROM AUTHOR]
