The initial intervention plan for recommendations for the PDS dentists for follow-up of the highest risk children (Program III) included an option of recalls every month during a three month period. Compliance by the PDS staff with the recommendation for follow-up was evaluated when the second follow-up for all children was completed. The child's local PDS-clinic was contacted and feedback in the form of a written list of the child's appointments in the PDS in the period from baseline to the second follow-up was received. There was no information about clinical procedures undertaken, only dates of appointments.
