Home-based toothbrushing interventions for parents of young children to reduce dental caries: A systematic review.

ABSTRACT

BACKGROUND: Dental caries is the most prevalent preventable condition in children. A key preventive home-based oral health behaviour is the adoption and maintenance of parental supervised toothbrushing until 8 years of age. AIM: To examine interventions promoting parental supervised toothbrushing practices to reduce dental caries in young children (<8 years old). DESIGN: Interventions promoting parental involvement in home-based toothbrushing in children under 8 years old and their impact on caries were subjected to review. Electronic databases (MEDLINE, EMBASE, PubMed, Web of Science, PsycINFO, Scopus, and the Cochrane Library), references, and unpublished literature databases were searched for relevant literature. RESULTS: Of the 10 176 articles retrieved, forty-two articles were included. The Theoretical Domains Framework was used to code intervention content, with the main domains addressed being knowledge (41/42), skills (35/42), and environmental context and resources (22/42). Sufficient descriptions of the intervention development, delivery, and evaluation were lacking, with only 18 studies being underpinned by theory. Twenty-nine studies explored the impact on caries yielding mixed results. CONCLUSIONS: There are few interventions targeting home-based oral health behaviours underpinned by theory and methodological rigour in their development and evaluation. This demonstrates a clear need for future interventions to be guided by complex intervention methodology.
