About this study

Official title: Evaluation the Effect of Verbal & Written Information and the Previous Surgical Experience on the Anxiety of Third Molar Extraction

This study was performed on 66 patients who were admitted for third molar extraction under local anesthesia. The patients were divided into three groups: group 1 with verbal information, group 2 with written information, and group 3 with previous surgical experience. 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

Read the detailed description

This prospective study included 66 patients who underwent third molar extraction under local anesthesia in the Oral and Maxillofacial Department, Faculty of Dentistry, Ankara University, Turkey, between September and November 2018. The research protocol was approved by the ethical committee of the institute (No: 36290600/69), Ankara University, Turkey.

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 16 classification, and mesioangular and vertical positions according to the Winter 17 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.

The patients were divided into three groups:

Group 1: Patients who were given only basic information verbally Group 2: Patients with detailed written information about preoperative, intraoperative, and postoperative periods Group 3: Patients with previous experience and knowledge about third molar extraction Previous experience was determined before giving the questionnaires. The patients were randomly assigned to group 1 or 2 using an online random allocation software (www.randomization.com). Information was provided on how to complete questionnaires. STAI-S, MDAS, DFS, and VAS were applied to all patients 15 min before the surgery in the waiting room. The demographic data section (age and sex) in the form was filled out by the researcher.

The surgery was carried out under local anesthesia, with no pharmaceutical premedication or sedation. The surgical procedures were performed by a single experienced surgeon in the oral surgery clinic. After the surgery was completed, the patients were taken to the waiting room, and prescribed medications were given. STAI-S, MDAS, DFS, and VAS were reapplied after the surgery.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Spielberger State Anxiety Inventory (STAI-S),Behavioural

    STAI is one of the most frequently used scales in anxiety research, although it is not a specific scale for dental anxiety

  • Dental Fear Scale (DFS)Behavioural

    DFS is a scale developed by Kleinknecht used to determine dental fear in different dimensions. This is a Likert-type scale with a score of 1-5. It has 20 items. It examines the level of fear in terms of dentist avoidance, somatic symptoms of fear, and fear of various applications in dentistry practice

  • Modified Dental Anxiety Scale (MDAS)Behavioural

    MDAS was developed by Humphris et al. by adding a question related to injection. The scale consists of five-point Likert-type rating with five options. The scoring in this scale varies between 5 and 25

  • Visual Analog Scale (VAS)Behavioural

    VAS is ideal for evaluating situations that cannot be measured using digital and oral information. In the present study, a scale comprising 100-mm closed-end line was used to measure the anxiety level. One end of the scale was labeled as "no anxiety" and the other end as "maximum anxiety imaginable

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Evaluation of anxiety with Spielberger State Anxiety Inventory(STAI-S) between groups preoperatively and postoperatively

    Spielberger State Anxiety Inventory (STAI) is one of the most frequently used scales in anxiety research, although it is not a specific scale for dental anxiety. The inventory has 2 different scales, each with 20 items, showing the state and trait anxiety levels: STAI-state is used to determine a patient's current anxiety level, and STAI-trait is used to determine a patient's underlying (ongoing/personality) anxiety level. All 20 items are rated on a 4-point scale. The total score obtained can range from 20 to 80. STAI scores are commonly classified as "no or low anxiety" (20-37), "moderate anxiety" (38-44), and "high anxiety" (45-80). We used only STAI-S

    Measured: 2 minutes

  2. Evaluation of anxiety with Dental Fear Survey(DFS) between groups preoperatively and postoperatively

    DFS is a scale developed by Kleinknecht used to determine dental fear in different dimensions. This is a Likert-type scale with a score of 1-5. It has 20 items. It examines the level of fear in terms of dentist avoidance, somatic symptoms of fear, and fear of various applications in dentistry practice

    Measured: 2 minutes

  3. Evaluation of anxiety with Modified Dental Anxiety Scale(MDAS) between groups preoperatively and postoperatively

    MDAS was developed by Humphris et al. by adding a question related to injection. The scale consists of five-point Likert-type rating with five options. The scoring in this scale varies between 5 and 25

    Measured: 1 minute

  4. Evaluation of anxiety with Visual Analog Scale (VAS) between groups preoperatively and postoperatively

    VAS is ideal for evaluating situations that cannot be measured using digital and oral information 25. In the present study, a scale comprising 100-mm closed-end line was used to measure the anxiety level. One end of the scale was labeled as "no anxiety" and the other end as "maximum anxiety imaginable."

    Measured: 1 minute
