Applying Social Practice Theory to Explore Australian Preschool Children's Oral Health

Introduction: Despite substantial research and provision of dental care, significant morbidity remains for children’s oral health. Guided by social practice theory (SPT), this research moves away from the often-ineffective focus on changing individual behavior to rethinking the centrality of the social world in promoting or undermining oral health outcomes. We define social practice as a routinized relational activity linking and integrating certain elements (competence, materials, and meanings) into the performance of a practice that is reproduced across time and space. Objective: To investigate oral health in preschool children in Perth, Western Australia, using social practice theory. Methods: With no definitive methodology for investigating SPT, we chose focused ethnography as a problem-focused, context-specific approach using mainly interviews to investigate participants’ experience caring for their children’s oral health. The focus of analysis was the practice of oral health care, not individual behavior, where themes identified from participants’ transcripts were organized into categories of elements and performance. Results: Eleven parents, all of whom were married or partnered, were interviewed in 2021. Findings identified social practices relevant to oral health within parenting and family relations linked to routine daily activities, including shopping, consumption of food and beverages, and toothbrushing. Oral health literacy was reflected in integrating competence, materials, and meanings into performing oral health care, notably preferences for children to drink water over sugary beverages and information often being sourced from social media and mothers’ groups rather than health providers. Conclusion: Focusing on social practices as the unit of analysis offers a more layered understanding of elements in young children’s oral health care that can indicate where the problem may lie. Findings provide an opportunity to consider future research and policy directions in children’s oral health.
