Should Preoperative Information Before Impacted Third Molar Extraction?

The main objective of the present study was to evaluate the effects of different preoperative information techniques (verbal, written, video with background audio, and silent video with subtitles) on patients' anxiety levels before and after third molar extraction. The secondary objective was to determine the superiority of the information methods evaluated over each other. We hypothesized that the information provided by video with or without background audio would decrease preoperative and postoperative anxiety levels more effectively than information provided by verbal and written methods.

This prospective study included 86 patients who underwent third molar extraction under local anesthesia in the Oral and Maxillofacial Department, Faculty of Dentistry, Ankara Yıldırım Beyazıt University, Turkey, between May and June 2022. The research protocol was approved by The Yıldırım Beyazıt University Oral and Health Training and Research Hospital Ethical Committee,Turkey. (No: E-2022-14) Spielberger State Anxiety Inventory (STAI-S), Dental Fear Scale (DFS), Modified Dental Anxiety Scale (MDAS), and Visual Analog Scale (VAS) are commonly used questionnaires for dental anxiety. The latter asked only about age and sex. They were used together before and immediately after surgery to obtain better results in this study.

After examining the panoramic radiographs, patients who underwent extraction were included in Classes 1 and II, Positions A and B according to Pell-Gregory classification, and mesioangular and vertical positions according to the Winter classification.

Each patient was examined by the researcher. The patients were informed about the procedure, and written informed consent was obtained from the patient's preoperative assessment clinic. If a patient had additional questions, they were included as part of the investigation Patients were assigned to 4 groups: Group 1 was informed via silent video with subtitle, group 2 was informed via video with background audio, group 3 was informed with written information brochure, group 4 (control group) was informed preoperatively verbally. The Spielberger State Anxiety Inventory (STAI-S), Dental Fear Scale (DFS), Modified Dental Anxiety Scale (MDAS), and visual analog scale (VAS) were used pre- and postoperatively to evaluate the dental anxiety of patients
