Abstract: This paper aims to explore how the construction of oral health science popularization bases in dental hospitals can address the rising incidence of early childhood caries （ECC） by promoting knowledge about the causes and prevention of ECC and enhancing caregivers’ skills in maintaining children’s oral health. By analyzing the current status of oral health among young children in Tianjin,new strategies based on multidisciplinary collaboration,information technology support,and innovative working methods are proposed. The research findings indicate that by optimizing resource allocation,strengthening the construction of science popularization teams,expanding communication channels,and integrating new media technologies,it is possible to significantly increase caregivers’ awareness of early childhood oral health,reduce the incidence of ECC and its complications.

Key words: early childhood, oral health, science popularization base, prevention measures
