Design outcomes

Primary

MeasureTime frame
Dental anxiety measured using the Modified Child Dental Anxiety Scale (MCDAS) score at 12 months post-randomisation

Secondary

MeasureTime frame
1. Dental anxiety (MCDAS) measured at the end of the course of treatment. 2. Child health-related quality of life and oral health-related quality of life (Child Health Utility-9D and CARIES-QC) at the end of the course of treatment and 12 months post-randomisation. 3. Dental anxiety of the parent/carer (Modified Dental Anxiety Scale) measured at the end of the course of treatment and 12 months post-randomisation. 4. Attended, cancelled, and missed appointments will be recorded during the course of treatment and for the 12 month follow up period. 5. The need for referral to secondary care and use of sedation or general anaesthesia (GA) will be recorded throughout for children in both groups along with treatment provided.
