The aim of this work was to identify the effects of a preparatory procedure for providing face to face information on the levels of anxiety, physiological changes and pain of dental patients undergoing extraction of third molars. Participants 123 patients, 14 to 24 years, who required extraction of at least one third molar in a dental session. The patients were selected and randomly allocated into two groups (Control and Experimental). The experimental design was divided into (1) Identification Questionnaire; (2) Pre-Surgical; (3) Providing Prior Face to Face Information (Experimental Group); (4) Surgical Procedure; (5) Immediate Post-Surgical; (6) Mediate Post-Surgical; and (7) Suture Removal. The Identification Questionnaire presented open and closed questions about habits, dental experience and history of drug use. The Pre-Surgical moment involved physiological measurements (blood pressure and heart rate), the implementation of the Trait-State Anxiety Inventory (STAI), Dental Anxiety Scale (DAS), and the McGill Pain Questionnaire (Sensory Pain Rank Index, Affective Pain Rank Index, Present Pain Intensity and Global Assessment of Pain Experience). After the preoperative phase, patients in the Experimental Group received prior face to face information about extraction surgery. The same measures of Pre-Surgical moment were repeated in the Immediate Post-Surgical, Mediate Post-Surgical and Suture Removal moments. Data obtained by interview and scores obtained by instruments STAI, DAS and McGill, and the measures of the equipment measuring physiological measures were analyzed using Chi-Square, Analyses of Variance with Mixed Model and Tukey (?=0,05). It was found that there was no statistically significant difference between the means scores on the physiological assessments with the DAS and STAI instruments at all moments between the groups (between groups analysis) and analysis of each group in moments (Intra-group analysis). Data analysis in the reporting of pain suggests that there is significant reduction in the Sensory Pain Rank Index at the moment immediately after surgery to Experimental Group patients (Immediate Post-Surgical: CG: 6,83 - EG: 4,43, p?0,0001). These results suggest that prior face to face information was efficient for the significant decrease in the reports of sensory pain immediately after extraction, but was not effective for reduces physiological responses measures of anxiety and of others reports pain on third molar extraction. These results indicate that prior face to face information was efficient for significant decrease in reports of sensory pain immediately after extraction, but was not effective for reducing physiological measures and anxiety and other pain responses reports on third molar extraction (AU)
