Type D Personality, Somatization and Perceived Social Support in Temporomandibular Joint Disorders

This study aimed to investigate the relationship between Type D personality traits, somatization disorder, and perceived social support in individuals diagnosed with temporomandibular joint disorders. Temporomandibular joint disorders are musculoskeletal and neuromuscular conditions that affect the jaw joint, chewing muscles, and related structures, leading to pain and functional difficulties. Psychological and social factors, such as personality traits and emotional distress, have been shown to influence the development and persistence of these disorders. The research was conducted as a prospective cross-sectional study between February and June 2025 in Gaziantep City Hospital. Adult participants between 18 and 65 years of age who were diagnosed with temporomandibular joint disorders were compared with healthy individuals of similar age and gender. Participants completed validated questionnaires that assessed mandibular function, anxiety and depression symptoms, Type D personality traits, somatization tendencies, and levels of perceived social support. The purpose of this study was to provide a more comprehensive understanding of the psychological and social dimensions that may contribute to the onset and course of temporomandibular joint disorders.
