Dental caries remains an important health issue, also in small children. In order to improve this situation, oral health intervention programs are developed. The evaluation of these programs is often limited to the follow-up of oral health parameters and/or reported oral health behaviors. In addition to the evaluation of outcome measures, process evaluation and an evaluation of the implementation fidelity are important.
Based on data obtained from a recent oral health intervention program in small children in Flanders (Belgium), the Smile for Life project, several issues regarding the set-up, conduct and evaluation of an oral health intervention will be discussed.
