Validation of a Chinese version of the dental anxiety inventory

Objectives: To translate the English version of Dental Anxiety Inventory (DAxI) and its short-form (SDAxI) and to validate their use in Hong Kong Chinese. Methods: The DAxI and SDAxI were translated into Chinese. A total of 500 adults (18-64 years) were interviewed, the Chinese DAxI, Symptom Checklist 90 (SCL-90), Depression Anxiety Stress Scales (DASS) and State-Trait Anxiety Inventory (STAI) were completed. Based on their initial DAxI scores, 135 interviewees were invited to attend a dental examination 1 month later. Then, the subjects completed the DAxI again, together with Beck Anxiety Inventory (BAI) which measured the state anxiety level of the participants. Two months after the initial interview, all 500 subjects were asked to complete the DAxI again. Another 300 adults were recruited and interviewed for the SDAxI validation. Results: Cronbach's alpha of the Chinese DAxI and SDAxI were 0.77 and 0.80 and the test-retest correlation coefficients were 0.90 and 0.84, respectively. High correlation between BAI and DAxI scores and its stability over time supported construct validity of the Chinese DAxI. Small positive correlations between the DAxI and other subscales of the SCL-90, DASS and STAI supported discriminant validity of the instrument. The SDAxI demonstrated comparable validity and reliability with DAxI. Conclusion: The translated Chinese DAxI demonstrated good validity and reliability. It is available for use in dental anxiety research in adult Chinese. In situations where a short-form is desirable, the Chinese SDAxI is a simple, valid, reliable and interpretable scale for measuring dental anxiety in both research and dental practice. © Blackwell Munksgaard, 2005.postprin

Stimuli involved in dental anxiety: What are patients afraid of? A descriptive study

Background: Dental anxiety is a psychological response inducing aversion following a dental ill-defined stimulus, non-imminent and perceived as potentially dangerous. It is better to intervene during childhood than to resolve in adulthood when dental anxiety is more settled. Aim: The purpose of this study is to determine the nature of dental anxiety-provoking stimuli in young patients. Design: A questionnaire was submitted to 566 children between 3 to 18 years in health institutions and schools in Brussels, Belgium. The items were divided into 3 groups: environment (ENV), local anaesthesia (LA), and intervention (INT) and summarized through averaging per group. Descriptive analysis and non-parametric testing were combined with logistic regression after discretization, above mild, for the group averages. Results: About 7.2% of the respondents expressed high to severe dental anxiety. Several items presented a clear bimodal distribution dividing the population in fearless and fearing patients, for example, sight and feel of the syringe, sight and taste of blood and extraction. Others presented with a gradually lower incidence with increasing fear level. Fear for the environment was generally low. Gender and ethnic origin contribute significantly to the prediction of fear caused by LA. For fear caused by INT, first the place of questioning enters the models, thereafter follow: negative experience, frequency of dental visit, and gender (P <.05). Conclusions: While the dental environment is in general not causing fear, the invasive part of the anaesthesia and the invasive dental procedures are involved. Fear seems to be related to culture, previous experience, and gender.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Referrals to a secondary care dental clinic for anxious adult patients: implications for treatment

This study aimed to determine the methods suggested by general dental practitioners for management of patients with dental anxiety whom they refer to a dental hospital setting, the treatment modalities eventually used with such patients and the relationship between patients previous sedation experience and the current referral. Consecutive referral letters (n=125) for management of patients with dental anxiety over a 16 month period were analysed for content, including reason for referral and suggested treatment modalities. Patient records were also examined for previous sedation experience. From 115 referrals eligible for analysis, the dentists requested management of anxiety using pharmacological methods in 113 referrals with only two referrals mentioning psychologically-based treatments. In secondary care, 29% of the adult referrals opted for dental treatment using psychological techniques alone. In spite of the efficacy of psychological treatments for dental anxiety, primary and secondary care dentists appear not to be suggesting or promoting their use for patients with dental anxiety. Further research into the availablility of, and barriers to accessing the full range of services for those with dental anxiety, including patient perspectives, needs to be undertaken

Atraumatic restorative treatment and dental anxiety in outpatients attending public oral health clinics in South Africa.

Contains fulltext : 53216.pdf (publisher's version ) (Closed access)OBJECTIVES: This study was undertaken to test the hypotheses that using the atraumatic restorative treatment (ART) approach results in lower patient anxiety and that lower anxiety leads to higher restoration/extraction ratios. METHODS: The test group of dental operators (n = 9) was trained in ART The control group (n = 11) was not, and did not apply ART The Short Form of the Dental Subscale of the Children's Fear Survey Schedule (CFSS-SF) and Corah's Dental Anxiety Scale (DAS) were used to assess patient anxiety after ART (test group) and after traditional restorations (control group). The restoration/extraction ratio calculated for primary (children) and permanent dentitions (adults) per operator was based on 12-month treatment statistics. Dental anxiety assessments were analysed using ANOVA. Differences were compared using the t-test and corrected for confounding factors (ANCOVA). The Pearson correlation coefficient was used to measure the correlation between dental anxiety levels and restoration/extraction ratios. RESULTS: The mean CFSS-SF score for test-group children was statistically significantly lower than for the control-group children. The mean DAS score for test-group adults was statistically significant lower than the control. No significant correlation was observed between dental anxiety level and restoration/extraction ratio per operator for both dentitions in both groups. Conclusion: The first hypothesis was accepted; the second, rejected. Although dental anxiety scores were lower both in child and in adult patients treated by ART than in those who received traditional restorative treatments, this positive effect had not resulted in higher restoration/extraction ratios
