Study population: This study included adult patients diagnosed with TMDs seeking care at the oral and maxillofacial surgery department of Faculty of dentistry, Mansoura university. All patients were eligible for splint therapy and were randomly assigned to postgraduate dentists with advanced clinical training in TMD management. Dentists were with advanced training in TMD management. Participants were followed for six months after the initiation of treatment.

Who may be able to join

  • Diagnosed with TMDs according to Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) guidelines, specifically disc displacement with reduction.
  • Exhibiting symptoms of stress or anxiety, as identified by the baseline DASS-10 screening.

About this study

Official title: Personality Traits of TMD Experts Really Matters, A New Era in TMD Management

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.

Read the detailed description

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.

Study groupRoleWhat they receive
TMD Patients Assigned to DentistsPatients 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

    Measured: 6 months post-treatment

Secondary outcomes (3)
  1. Patient Satisfaction with Treatment

    Patient satisfaction was measured using a structured questionnaire developed to assess overall satisfaction with the treatment process, fulfillment of expectations, and perceived treatment effectiveness. Responses were scored on a Likert scale, with higher scores indicating greater satisfaction.

    Measured: 6 months post-treatment

  2. Adherence to Splint Therapy

    Patient adherence was assessed using two self-reported indicators: (1) average number of hours per day the splint was worn, and (2) number of days per week the splint was used consistently. Higher scores reflect better adherence.

    Measured: 6 months post-treatment

  3. Change in Psychological Distress (DASS-10 Score)

    Psychological distress was measured using the 10-item Depression, Anxiety, and Stress Scale (DASS-10). The change in score from baseline to 6-month follow-up reflects improvement or worsening of psychological wellbeing.

    Measured: Baseline and 6 months post-treatment
