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

Temporomandibular disorders are multifactorial conditions often accompanied by psychological distress, chronic pain, and functional limitations. While splint therapy remains a common conservative intervention, patient adherence and satisfaction with treatment can vary widely and are often influenced by interpersonal dynamics between provider and patient. Emerging literature in medicine and dentistry suggests that provider personality traits play a critical role in shaping communication style, patient engagement, and ultimately clinical outcomes. However, few studies have systematically examined this relationship within dental practice, particularly in the management of TMDs. This study adopts a prospective, randomized design. Thirty dentists treating TMD patients are assessed for their personality traits using the BFI-2-S, which evaluates five core dimensions: conscientiousness, agreeableness, extraversion, openness, and negative emotionality. Three hundred TMD patients are randomly assigned to one of the participating dentists and undergo a standardized treatment protocol involving splint therapy. Dentists follow a structured communication and counseling framework aimed at enhancing the quality of interaction and patient education. Patient outcomes are assessed at baseline and after six months of therapy. The key outcomes include: Quality of doctor-patient communication, measured using the PCCS, Treatment satisfaction using a structured questionnaire, Adherence to splint therapy (hours/day and days/week), Psychological well-being measured by the DASS-10. Statistical analyses include correlation to assess the association between dentist personality traits and patient outcomes. This study has the potential to uncover meaningful links between provider personality and clinical success in TMD management. Results may guide the development of more effective communication protocols, inform training and self-awareness initiatives for dental professionals, and promote patient-centered care grounded in both technical and interpersonal excellence.
