In 2017, the ‘Uitblinkers’ intervention was developed to improve toothbrushing behaviour among young children. This interview method focuses on identifying parents’ barriers to brushing their children’s teeth, and promoting parenting strategies to tackle the identified barriers. Twenty-one trained dental therapists from twelve dental practices applied the ‘Uitblinkers’ intervention among parents of three-year-old children. Nine months after the training, focus group- and telephone interviews were conducted to evaluate the feasibility and appreciation of the intervention in dental practice. Findings of this study show that the ‘Uitblinkers’ intervention offers a feasible approach to improve children’s toothbrushing behaviour. Dental therapists were generally positive about the interview method, the supporting materials and the reactions of parents. Some (logistic) barriers to adoption were identified which, if resolved, would improve the implementation of the intervention in dental practice.
