How Dentists' Personality Traits Affect Communication and Treatment Outcomes in TMD Patients

This prospective, longitudinal study investigates the influence of dentists' personality traits on patient-reported outcomes among individuals with temporomandibular disorders (TMDs) undergoing splint therapy. Dentists are assessed using the Big Five Inventory-2 Short Form (BFI-2-S), and patients are randomly assigned to them. Key outcomes measured six months after treatment include patient-centered communication, treatment satisfaction, adherence to splint therapy, and changes in psychological distress using validated scales such as the Patient-Centered Communication Scale (PCCS), a structured satisfaction questionnaire, and the DASS-10. The study explores whether traits such as conscientiousness, agreeableness, extraversion, openness, and emotional stability are associated with better patient outcomes in TMD care. This research aims to enhance patient-centered treatment by integrating personality-informed clinical practice and tailored communication strategies.
