Brief Summary

Establishing good oral health-related habit is challenging among younger children, especially for preschool children with special needs, as they have physical, mental, sensory, behavioural, emotional, and chronic medical conditions that requires health care beyond the routines. Existing evidences showed that children with special needs have poorer oral health status and more challenging behaviours than their counterparts in main stream schools. Visual pedagogy, such as social stories, have been applied to teach a variety of skills or behaviours to individuals with special needs. They are short stories demonstrating the target skill or behaviour, and then the readers are expected to perform the target skill or behaviour following the demonstrations. Giving the evidence that children with special needs can understand complex situations and learn new practices by using those stories, we expect to apply a package of structured social stories to modify oral health-related behaviours (tooth brushing, healthy eating, dental visit), and thereby, improve oral health status among preschool children with special needs. Establishment of good oral-health related behaviours in early childhood will benefits children in their future life. Additionally, visual pedagogy-assisted oral health education is relatively easy and safe to implement. If proven effective, social story-based preventive care can be recommended to special children globally.
