Primary outcomePrimary: Change in Systolic Blood Pressure (SBP) — 115.04; 112.04; 113.58; 113.58 mm Hg — p=0.579
Summary
This study evaluates whether physician-guided visual information provided before impacted mandibular third molar surgery can improve hemodynamic stability during the perioperative period. Participants are assigned to one of three preoperative information methods: standard verbal information, real surgical video information, or 3D animation video information. Changes in systolic blood pressure, diastolic blood pressure, heart rate, and oxygen saturation are assessed at multiple perioperative time points to determine whether visual information reduces stress-related physiologic responses. The study also examines whether these information methods influence preoperative dental fear.
