Title: Improving Oral Health for Children with Autism Spectrum Disorders
Abstract: Autism Spectrum Disorders (ASD) is a spectrum of developmental disorders characterized by impairments in communication and social skills. Maintaining good oral health requiring special care is a challenge because of multiple learning, communication and cogitative impairments. This has been the focus of my thesis with a theme of research relating to special care dentistry.
A systematic review of the oral health status of individuals with autism spectrum disorders was undertaken across five electronic databases employing PRISMA guidelines. The initial search yielded 727 papers, among which 36 were identified as potentially effective papers and 11 ‘effective’ case-control studies informed this review. Variations in oral health existed among children with and without ASD in terms of dental caries experience, periodontal health, malocclusion, dental injuries and bruxism. This has implication for special care practice and policies.
To understand ASD and oral health in the Hong Kong context a population-wide oral epidemiological study was undertaken among 17 randomly selected registered Special Child Care Centres. An age (±6 months) and gender matched sample of children from mainstreams preschools were recruited as the ‘control group’. Comprehensive oral health assessments were undertaken for over 500 children. Difference in clinical oral health status existed among preschool children with and without ASD in terms of dental caries experience (dmft>0), periodontal health (pp<0.001).
A clinical trial was undertaken to evaluate the effectiveness of a tooth-brushing visual pedagogy to improve oral health and enhance oral self-care among children with ASD in both intervention and control groups. Improvements in oral hygiene status and gingival health were observed over the 6-month period. Regression analyses identified the visual pedagogy intention was a significant factor associated with improved oral health (p This has implications for safeguarding and promoting good oral health among children with ASD in Hong Kong and beyond.
