Impact of preoperative patient information on anxiety and physiological responses in mandibular third molar surgery: A randomized controlled trial.
Article in Medicina oral, patologia oral y cirugia bucal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07018115 (The Effect of Preoperative Patient Information Strategies on Anxiety and Hemodynamic Responses During Third Molar Extraction), which is not on this map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
backgroundThis 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
methodsA 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).
resultsVAS 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 registrationClinicalTrials.gov Identifier: NCT07018115; Registration date: 10 June, 2025.
conclusionsAlthough 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.
