There is limited evidence on patient-based outcomes for paediatric dental treatment under GA. This study in 2 hospitals in New Zealand used a special children's questionnaire on OHQoL, and parents or carers of 214 consecutively treated children were asked to complete this while children were undergoing treatment. A follow-up questionnaire was given within 1-4 weeks of treatment.

Complete baseline data were returned for 202 children, and follow-up data for 130. Most data were recorded by parents. At the follow-up, 89 children were considered much improved in OHQoL after treatment, 20 were a little improved, 18 had not changed, and 2 were worse, according to the opinions of the adults.
