Should Preoperative Information Before Impacted Third Molar Extraction?

Not Applicable

Completed

• Conditions: Dental Anxiety; Impacted Third Molar Tooth

• Registration Number: NCT05548790
• Lead Sponsor: Ankara Yildirim Beyazıt University

Brief Summary

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.

Detailed Description

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

Primary Outcome Measures

Name	Time	Method
Evaluation of anxiety with Spielberger State Anxiety Inventory(STAI-S) between groups preoperatively and postoperatively	2 minutes	STAI-S is a 20-item scale that determines the current anxiety level of the patient with reliability and validity in Turkish. Widely used to assess anxiety, the STAI explores the transient state of anxiety, and patients report how they are feeling at the current time point. It is scored using a 4-level frequency scale ranging from 0 to 3. The total score ranges from 20 to 80, higher scores indicates higher anxiety
Evaluation of anxiety with Dental Fear Survey(DFS) between groups preoperatively and postoperatively	2 minutes	DFS is which consists of 20-items is used to determine physiological responses to dental stimuli via a Likert-type scale ranging from 1 to 5. Total scores change from 20 to 100 point. It collects the evaluation of dental anxiety under 3 headings. The first 2 questions assess avoidance of dentistry, questions 3-7 show physiological arousal, and questions 8-20 predict fear of certain situations
Evaluation of anxiety with Modified Dental Anxiety Scale(MDAS) between groups preoperatively and postoperatively	1 minute	MDAS which is created by adding one question to the Corah Dental Anxiety Scale have 5-item questionnaire with 5-point Likert-type scale. Scale shows points between 5 and 25
Evaluation of anxiety with Visual Analog Scale (VAS) between groups preoperatively and postoperatively	1 minute	VAS is a digital and verbal assessment scale used to measure anxiety. A closed-ended scale of 0-100 mm ("0" no anxiety, "100" maximum imaginable anxiety) was used in the study, and participants were asked to put a mark on the VAS scale, which they thought showed the degree of their current anxiety
