Severe Early Childhood Caries

This study aims to address the high prevalence and recurrence rate of severe early childhood caries (S-ECC) by breaking away from the traditional single biological factor perspective and introducing the theories of "24-hour activity behavior" and "family psychological stress". By collecting clinical and behavioral data from 1,200 preschool children and their parents, it explores the association pathways between parental burnout, children's executive function, sleep/dietary behaviors and S-ECC, and builds a high-precision risk prediction model to provide evidence-based support for the clinical development of personalized prevention strategies.
