Actual (reported)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.

Actual (reported)Patient-Centered Communication Score (PCCS)
Patient-centered communication was assessed using the validated Patient-PCCS. This self-reported measure evaluates the quality of dentist-patient communication from the patient's perspective, including aspects such as empathy, clarity, and involvement in decision-making. Scores range from low to high, with higher scores indicating more patient-centered communication. The outcome is used to determine the influence of dentist personality traits on perceived communication quality.

Patients diagnosed with TMDs were randomly assigned to dentists with varying personality traits. All patients received standardized splint therapy and were followed for six months. Key patient-reported outcomes-including communication quality, satisfaction with treatment, adherence to splint use, and changes in psychological distress (DASS-10)-were assessed to examine the influence of dentist personality on treatment effectiveness.
All participants received a stabilization splint for the management of TMDs, combined with a structured counseling protocol delivered by the assigned dentist.
