Early childhood caries (ECC) is a common disease. Its prevalence is highest in poor, socially disadvantaged, and minority groups. Dental treatment under General Anaesthesia (DGA) is common, especially among the youngest patients. Parental adherence to child's post-DGA dental treatment is varying. Non-attendance to preventive care appointments and dental check-ups after the DGA is also common. The primary aim of this study is to explore if a multi-professional (paediatrician and social worker) intervention after the child's DGA can increase the adherence to post-DGA dental care. The secondary aim is to compare its possible influence on children's oral health 18 months after the DGA. Our hypothesis is that multi-professional counselling and support after the DGA will lead to better adherence to the scheduled preventive dental programme and better oral health for these children in the long run.

In an earlier Finnish study 26% of the children did not attend to their first scheduled appointment after the DGA and during a four years follow-up period 63% of the patients had one or more no-shows.

Based on the assumption that reducing the amount of no-shows to half of the reported earlier (60% vs. 30%) is a clinically relevant result, we need 42 patients for both groups (alpha 0.05, beta 0.2, power 0.8).
