Clinical Trial Summary

It has been recognized that oral health education for parents is critical for the prevention of early childhood caries (ECC). Few parents practiced caries prevention procedures for their children in daily life, though. Inspired by Health Belief Model (HBM) and using text messaging as a vehicle, a novel intervention scheme will be developed in this study. The objective of the present randomized clinical trial (RCT) is to investigate the effectiveness of the HBM-based behavioral intervention using text message to reduce early childhood caries of children at age 4 through promoting the parental oral health care behaviors (toothbrushing and sugar intake control) for their young children compared to conventional oral health education. This RCT will recruit child-parent dyads in 26-36 child help centers or kindergartens with nursery classes located in Hong Kong. A total of 518-628 dyads will be recruited and randomly allocated into the test or control group with a 1:1 ratio. For parents in the test group, the intervention will consist of a set of HBM-based text messages sent regularly in the following 48 weeks. A standard text message will be sent to the parents in the control group. The primary outcome will be dental caries measured by dmft/dmfs of the children at 4 years old. By HBM-based intervention via a low-cost text messaging vehicle, it should be able to help the parents establish proper oral health behaviors for their children and safeguard the oral health of children in Hong Kong.
