The aim of the present study was to establish validity for Dental Anxiety Scale in children by their drawings. Dental treatment was provied for 35 children in the ages of 4 to 8, using the quadrant approach. The children's anxiety arising during dental treatment was measured by Modified Sheskin's Criteria(Dental Anxiety Scale, DAS). After reliability analysis of Dental Anxiety Score, it was compared with Faces Pain Scale and was tested for their correlation. Thereafter the several factors having an effect on Dental Anxiety Scale were examined. A significant correlation(r=0.2610) was found between the two scales and Dental Anxiety Scale was high significantly in 4-6 score of Faces Pain Scale. The findings suggested that the Dental Anxiety Scale is a valid means of assessing child dental anxiety status in a clinical context and the Dental Anxiety Scale can be affected by 'Age', 'Gender' and 'Reaction in the past'.

Objective: To determine the changes in dental anxiety, state anxiety, and trait anxiety levels of patients and their parents after 3 months of active orthodontic treatment. Methods: We evaluated 120 patients and one parent of each patient. State Anxiety (STAI-S), Trait Anxiety (STAI-T), and Corah's Dental Anxiety Scale (DAS) were administered before orthodontic treatment (T1) and after 3 months of treatment (T2). Differences in scores between T1 and T2 were compared using paired-sample t-tests and the relationship between the scores of the DAS and the STAI were analyzed using a bivariate two-tailed Pearson correlation test. Results: Dental anxiety and state anxiety levels decreased among the patients after adjustment to orthodontic treatment (p < 0.001). However, 3 months of treatment was not sufficient to decrease the anxiety levels of parents (p > 0.05). Patient trait anxiety affected patient state anxiety and dental anxiety (p < 0.01). Additionally, a significant correlation was found between patient dental anxiety and parent dental anxiety (p < 0.05). Conclusions: Dental anxiety and state anxiety levels decrease after patients become familiar with their orthodontist and they became accustomed to orthodontic treatment. However, 3 months is not a sufficient length of time to decrease parental anxiety levels.

Background: This study aimed to assess the course of anxiety and pain during lower third molar (LTMo) surgery and explore the role of mobile and single-channel electroencephalography under clinical and surgical conditions. Methods: The State-Trait Anxiety Inventory (STAI), Corah's Dental Anxiety Scale (DAS), and Interval Scale of Anxiety Response (ISAR) were used. The patient self-rated anxiety (PSA), the pain felt during and after surgery, EEG, heart rate (HR), and blood pressure (BP) were assessed. Results: The Attention (ATT) and Meditation (MED) algorithms and indicators evaluated in this study showed several associations. ATT showed interactions and an association with STAI-S, pain during surgery, PSA level, HR, and surgical duration. MED showed an interaction and association with DAS, STAI-S, and pain due to anesthesia. Preclinical anxiety parameters may influence clinical perceptions and biological parameters during LTMo surgeries. High STAI-Trait and PSA scores were associated with postoperative pain, whereas high STAI-State scores were associated with more pain during anesthesia and surgery, as well as DAS, which was also associated with patient interference during surgery due to anxiety. Conclusions: The findings suggest that single-channel EEG is promising for evaluating brain responses associated with systemic reactions related to anxiety, surgical stress, and pain during oral surgery.

Purpose : The purpose of this study was to identify and assess factors that may contribute to pain of patients undergoing implant surgery. Materials and Methods: A total of 24 patients who underwent implant surgery were included in the study. Each patient's anxiety was measured using Corah's dental anxiety score(DAS) and modified Spielberger's state-trait anxiety inventory(STAI) immediately after the operation. Also, level of pain was measured using visual analog scale(VAS) during the operation and 48 hours after the surgery. The effect of various factors, such as demographic variables, previous dental experiences and operation time were also analyzed. Results: Postoperative pain levels were relatively low than expected. However, DAS and STAI were high among patients, and it showed that patients had anxieties about implant surgery according to DAS and STAI values. The previous dental experience did not affect the pain level, but the duration of surgery and the presence of accompanied advanced surgery did. Conclusion: To reduce patient's pain, proper management of anxiety will be required and careful attention is needed when performing local infiltration.

The aim of this study was to confirm the effectiveness of learner-centered teaching models to reduce the dental anxiety. 18 children with age of 10 at the case group and 22 children with age of 10 at the control group was completed. Children from case group were participated in learner-centered oral health education, while those from control group were participated in instructor-led oral health education. Dental Anxiety Scale (DAS) at each groups were measured before oral health education, after then, oral health education of two types at each groups were separately conducted during 1-hour, 2 times. Learner-centered oral health education adapted the systematic desensitization (Tell-Show-Do) was conducted for case groups. Instructor-led oral health education was performed by using the presentation file (PPT). The change of Dental Anxiety Scale (DAS) were compare between case and control groups to evaluate the effect of learner-centered teaching type. After oral health education, DAS of the case and control groups at the baseline were 9.61 and 11.14, respectively, and the average DAS decline of case and control groups after oral health education were 2.48 and 0.55, respectively. These findings show that a learner-centered teaching type is an effective oral health program to reduce of dental anxiety in childhood.

The purpose of this study was to observe dental anxiety of second grade elementary school children projected in the drawing of dental treatment situation. The subjects of study were 213 school children. Questionnaire survey was done regarding their experience of pain and fear during the dental treatment and children's attitude toward the dental treatment and dentist. Drawings were analyzed using criteria modified from Dental Anxiety Scale(DAS) by Sheskin et al. The mean anxiety score was 2.00 and the range was from 0 to 6. The mean anxiety score was 2.82 in untreated children and 1.92 in treated children (P<0.05). The mean anxiety score was 2.00 in boys and 1.99 in girls. The rates of children who showed severe fear and pain of the subjects were 8.2% and 5.6%. The rates of children who showed slightly or definitely negative attitude for dental treatment and dentists of the subjects were 19.9% and 4.6%.
