Özet
Background: Biopsychosocial factors, especially the psychological aspects are well established in etiology and pathogenesis of temporomandibular disorders (TMDs). The role of Type D personality, characterized by negative affectivity (NA) and social inhibition (SI) shown to correlate with adverse outcomes in chronic pain and distress, remains unexamined in TMDs. This study evaluated the association between Type D personality and TMDs. Methods: This cross-sectional analytical study evaluated Type D personality in patients with and without TMDs. Axis I diagnoses in the TMD group were established using the Turkish version of the DC/TMD protocol, and Type D personality was assessed across both groups using the Turkish version of the DS14 scale. Statistical analyses were performed with SPSS v20.0, and statistical significance was set at p < 0.05. Results: High NA (61.0% vs. 34.0%) and Type D personality (30.0% vs. 18.0%, p = 0.047) were significantly more prevalent in TMD patients than controls, while high SI prevalence did not differ significantly (43.0% vs. 31.0%, p = 0.079). Mean NA scores were significantly higher in TMD patients (p < 0.001, Cohen’s d = 0.54), as were mean SI scores on continuous analysis (p = 0.012, Cohen’s d = 0.36). Chi-square tests confirmed a significant association between Type D personality and TMD status (p < 0.05). Conclusion: Type D personality, especially its NA component, was significantly associated with TMD status in this sample. However, due to cross-sectional design and study limitations, these hypothesis-generating findings require confirmation in prospective, well-matched cohorts before clinical application.
