Background. Oral health promotion campaigns have been developed for parents of pre-school children, aimed at changing their behaviours in view of preventing caries. Often the process of intervention of these campaigns is not evaluated. Hence little information is available about the conditions under which a successful dental health promotion programme can be implemented. Aim. This study is aimed to evaluate the process of implementation of a longitudinal intervention programme to promote oral health in preschool children in Belgium. As this programme was implemented in an existing primary care organisation, the study also evaluates this setting as the context for implementation. Methods. Qualitative as well as quantitative methods were used to evaluate implementation fidelity. Questionnaire data from participants and health workers were statistically analysed and document analyses were performed to compare the registered actions with the planning manual. Results. Attendance was high, with on average 77% of all participants present at each scheduled contact moment of the intervention. Adherence to the program manual was quite good, as on average 52 and 72% of all attending families received respectively all materials and information as described in the manual. Moderating factors like a good use of facilitators, high participant responsiveness and high quality of delivery had a positive influence on implementation fidelity. Conclusions. Overall the program was implemented with high fidelity. Implementing a program in an existing well-baby program has many advantages but there are some threats too. The results of this process evaluation can contribute to a better understanding of the (lack of) success of the intervention.
