ABSTRACT
AIM: The aim of this study was to assess the effectiveness of the passivity to activity through live symbolic (PALS) after treatment modelling intervention to reduce child dental anxiety. METHODS: A convenience sample of consecutive 5- to 10-year-old dental patients were randomly assigned to intervention or control groups. Self-reported child dental anxiety was assessed at the start of each visit. At the end of each visit, children in the intervention group were introduced to a glove puppet, which acted as the PALS model. The intervention group children re-enacted the treatment they had just received on the puppet's teeth. At the end of each visit, the control children received motivational rewards only. The change in dental anxiety scores was examined by t-tests and analysis of covariance. RESULTS: The final analysis included 27 intervention children and 26 control children. For the intervention group, there were no statistically significant changes in dental anxiety over a course of treatment, between first and second preventive visits, between first and second invasive treatment visits, or between first attendance and subsequent recall attendance. For the control group, a statistically significant decrease in dental anxiety was observed between the first and second invasive dental treatment visits. CONCLUSION: The PALS after treatment modelling intervention was ineffective in reducing child dental anxiety.

BACKGROUND: A new version of the Modified Child Dental Anxiety Scale (MCDAS) was formed by adding a faces rating scale to the original numeric form. AIMS: To describe the psychometric properties of the faces version of the Modified Child Dental Anxiety Scale (MCDAS(f)), and to provide normative data for dental anxiety for children using the MCDAS(f). DESIGN: To determine the test-retest reliability, 287 schoolchildren aged 8-10 years completed the MCDAS(f) on two separate occasions 17 weeks apart. To determine the criterion validity, 207 schoolchildren aged 10-12 years completed the MCDAS(f) and the CFSS-DS at the same sitting. Construct validity was assessed using a cohort of 206 consecutive child dental patients and their parents. RESULTS: The MCDAS(f) showed good test-retest reliability (intraclass correlation coefficient = 0.80) and internal consistency (Cronbach's alpha = 0.82). The MCDAS(f) significantly correlated with the CFSS-DS (r = 0.80, P < 0.001). Dental anxiety assessed using the MCDAS(f) was related to the dmft (t = -2.17, P = 0.03), DMFT (t = -4.19, P < 0.001), and dental general anaesthetic experience (t = -4.46, P < 0.01). The mean MCDAS(f) score for the normative sample (n = 475) was 19.81 (95% CI: 19.20, 20.43). CONCLUSIONS: The MCDAS(f) is a reliable and valid measure of dental anxiety in children aged 8-12 years.
