A "family-school-hospital" collaborative oral health management model for preschool children: a prospective single-arm pre-post intervention study

Background

Early childhood caries (ECC) remains a global public health challenge, yet preschool children lack autonomy in health management and depend heavily on family and school environments. Population-based oral health management models have proven effective in other fields but are rarely implemented in Chinese preschool settings. This study aimed to establish and evaluate a "family-school-hospital" collaborative oral health management model for preschool children in Chengdu, China.
