Bridging the communication gap in autistic children, one picture at a time.

One of the main domains of paediatric dentistry is providing oral health care, especially to the children with special needs, like those affected with autism spectrum disorder (ASD). Such children exhibit poor oral hygiene primarily due to their limited communication ability, lack of joint attention, oversensitivity to sensory stimuli and motor coordination deficits. In such cases, multiple studies suggest and emphasize on the importance of early use of interventional services. Children affected with ASD tend to be visual learners, and therefore, are better suited for visual interventional methods. Amongst which, picture exchange communication system (PECS), originally developed by Bondy-Frost, is gaining rapid momentum. It is suggested to help individuals to initiate requests and communicate their needs via picture cards; hence aid in acquiring functional communication and speech, improve socio-communicative impairments, and decrease the behavioural problems. This scoping review aims to raise awareness on PECS amongst the dental fraternity, by emphasizing its usage pertaining to dentistry. PECS though rated hard, has proved to be beneficial in improving oral hygiene practices among autistic children.
