Abstract

The aim was to evaluate the effects of offering prior procedural and sensory information on anxiety responses of young people undergoing third molars extraction. The study included 83 patients, 14-24 years old, who needed extraction of at least a third molar in a dental session. The patients were selected and randomly assigned into two groups: Control and Experimental. The experimental design was subdivided into periods of times: Triage (Initial Interview, Pre-Surgical I and informative video for the experimental group); Extraction (Pre-Surgical II); and Suture (suture removal). The Initial Interview presented open and closed questions about habits, dental experience and drug use history. The Pre-Surgical I, Pre-Surgical II and Suture Removal times involved application of State-Trait Anxiety Inventory (STAI). The audiovisual resource about third molar extraction was presented only to the Experimental Group and immediately after watching the video, patients responded to the Questionnaire for informative video assessment. The data was obtained by interview, the scores were obtained by STAI and questionnaire for informative video assessment were analyzed using descriptive analysis, Chi-square, Fisher exact, mixed models for repeated measures (Proc Mixed in the SAS program) and Tukey-Kramer (p-value ? 0.05). The results showed that there was no change in anxiety scores on Triage and Extraction for the Experimental Group, ie, there was no increase in anxiety scores across the Extraction for patients who watched the informative video. This result is not observed in the Control Group, which showed an increase of anxiety scores on the day of extraction. It suggests possible effect of informative video to reduce anxiety in patients undergoing third molars extraction. Furthermore, it can be observed that the instrument fulfill their function to inform since patients report video contents in open questions. The tranquilizing effect of this preparatory procedure is emphasized because 90% of patients felt more relaxed or confident after the video display, as well as they liked to receive preoperative information and did a good evaluation. It can be concluded that the preoperative information, offered by an informative video, can lead to significant reduction of anxiety in patients undergoing third molars extraction. This type of procedure is effective in providing information and patients gave a positive evaluation of this preparatory procedure (AU)
