Status Quo and Advanced Progress in Oral Health Care and Treatment of Children with Autism Spectrum Disorder: A Literature Review.

Autism spectrum disorder (ASD) has become one of the fastest growing diseases in the world, causing a great burden to ASD children's families and society. Children with ASD face more disadvantages relating to their oral health than those without ASD. There is a positive correlation between prevalence of caries lesions and severity of ASD. Poorer oral hygiene, higher detection rates of dental calculus and far more frequent cases of gingivitis occur in children with ASD. Traumatic injuries and various types of malocclusions are more frequent in children with ASD. Poorer oral health care and treatment status are caused by multiple adverse factors. Ways of promoting effective oral health care and treatment include pretreatment counselling; improvement of the individualised treatment environment; routine behaviour guidance techniques (BGTs) including tell-show-do, distraction, role model presentation, voice control, visual education and social stories, encouragement and reinforcement; targeted BGTs including visual education, behaviour modelling, applied behaviour analysis (ABA) and systematic desensitisation; passive BGTs including protective restraint, pharmaceutically administrated sedation and general anaesthesia; oral health education for guardians; and interdisciplinary collaboration and professional dental care/treatment. Dentists, families with children with ASD and schools should cooperate to improve family-centred oral health care and treatment for ASD children not only in China, but also the whole world.
