Effect of Verbal and Written Information and Previous Surgical Experience on Anxiety During Third Molar Extraction

Purpose: Third molar extraction is a quite common surgical procedure that causes dental anxiety. This procedure affects patients physiologically and mentally. The type of information provided to patients is important to determine the level of their anxiety regarding the surgical procedure. Patients' experience is also a major determinant of dental anxiety It is subjective and perceived only by the patient. Questionnaires are tools used to determine and assess patient anxiety The present study evaluated the effect of verbal and written information and the previous surgical experience of patients on their anxiety before and after third molar extraction. Patients and Methods: A total of 66 patients who had been admitted for third molar extraction under local anesthesia were included. The patients were divided into 3 groups: group 1 was given verbal information, group 2 was given written information, and group 3 had had previous surgical experience. 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 dental anxiety. Results: The MDAS and VAS scores of all patients had decreased postoperatively (P = .012 and P < .001, respectively). The postoperative MDAS and VAS scores were lower than the preoperative scores in women (P = .007 and P < .001, respectively). The postoperative MDAS (P = .014 and P = .004, respectively) and VAS (P < .001 and P = .002) scores had decreased compared with the preoperative scores in groups 2 and 3. The preoperative and postoperative MDAS and VAS scores were similar in group 1. In addition, the preoperative and postoperative STAI-S and DFS scores were similar in all groups. Conclusions: All patients should be adequately informed about the third molar extraction procedure, even if they have previous experience. Providing detailed information reduced the postoperative anxiety of the patients. (C) 2019 American Association of Oral and Maxillofacial Surgeons
