Background:
This study aimed to investigate the impact of different patient information modalities on anxiety levels and physiological responses during the surgical extraction of impacted mandibular third molars.
Material And Methods:
A prospective randomized clinical trial was conducted involving 97 individuals undergoing surgical removal of impacted mandibular third molars. Participants were allocated into three groups: Control, verbal, and visual. Anxiety was measured using the Modified Dental Anxiety Scale (MDAS) and the State-Trait Anxiety Inventory (STAI). Heart rate, blood pressure, and oxygen saturation (SpO2) were recorded at five surgical stages. Pain was assessed using a Visual Analog Scale (VAS).
Results:
VAS scores did not differ between groups. Significant intergroup differences were observed in diastolic blood pressure after local anesthesia and in SpO2 during tooth extraction and postoperatively (p<0.05). All groups showed reductions in MDAS, STAI-T, and STAI-S from the preoperative to the postoperative period. MDAS decreased significantly in the control and visual groups, while STAI-T decreased in all groups (p<0.05). STAI-S showed no significant change.
Trial Registration:
ClinicalTrials.gov Identifier: NCT07018115; Registration date: 10 June, 2025.
Conclusions:
Although no significant differences were found between information methods in reducing anxiety, providing preoperative information may enhance patient comfort during third molar surgery. Further studies are needed to determine the most effective strategies for patient education.
