Background and Objectives

Tooth decay in preschool children, or early childhood caries (ECC), is one of the most prevalent diseases in children. It was reported that approximately half a population of 5-year-old Hong Kong children are suffering from ECC, with more than 90% of ECC left untreated.  


ECC causes pain and infection. Advanced caries will progress into the tooth pulp to eventually form a dental abscess. Further attention is drawn that compromised dentition significantly affects the children’s nutrition and consequently, their growth, development, and general health.  


Supported by The Hong Kong Jockey Club Charities Trust, Faculty of Dentistry of the University of Hong Kong launches the “Jockey Club Children Oral Health Project”. This project aims to screen Hong Kong’s preschool children for tooth decay, to control existing cavities and to prevent further decay.
