Evaluation of a "Picture Assisted Illustration Reinforcement" (PAIR) System for Oral Hygiene in Children with Autism: A Double-Blind Randomized Controlled Trial.
Picture cues during brushing cut gingivitis and plaque better than verbal-only teaching for school-age kids with autism.
01Research in Context
What this study did
The team tested a picture-based oral-hygiene program called PAIR. Kids with autism in special-ed classes got the 12-week program.
Half the kids saw step-by-step pictures while they brushed. The other half heard the usual verbal reminders only.
What they found
After 12 weeks the picture group had cleaner teeth and healthier gums. The verbal-only group showed little change.
The visual support made a clear, measurable difference for these autistic students.
How this fits with other research
Frame et al. (1984) got the same direction with neurotypical kids. They posted photos on the wall when plaque was low. Both studies show visuals beat words for tooth-brushing.
Martens et al. (1989) swapped pictures for tactile prompts with a deaf-blind student. Their success reminds us to pick the prompt the learner can sense.
Poon (2011) simply described participation gaps in autistic teens. The new RCT moves past description and shows one way to close an adaptive-skill gap.
Why it matters
If you run oral-care lessons for autistic learners, add clear picture strips. Tape them to the bathroom mirror or hand each child a laminated sequence. The tiny change costs nothing and may give you the same cleaner-teeth boost seen here.

03Original abstract
This study evaluated the potential of a novel pre-validated “Picture Assisted Illustration Reinforcement” (PAIR) communication system and conventional verbal techniques for Oral Health Education (OHE) in terms of dentition status, gingival health, oral hygiene status, and practices in 7- to 18-year-old children with Autism Spectrum Disorder (ASD). A double-blind randomized controlled trial was undertaken in a school for children with autism from July to September 2022. A total of 60 children were randomly assigned into two groups: a PAIR group (n = 30) and a Conventional group (n = 30). Cognition and pre-evaluation of all the children were assessed by standardized scaling measures. A pre-validated closed-ended questionnaire was administered to caregivers of both groups. At a 12-week post-intervention, a clinical examination was performed using the World Health Organization (WHO) Oral Health Assessment form 2013, gingival and Oral Hygiene Index Simplified (OHI-S). The gingival scores in the PAIR group (0.35 ± 0.12) exhibited a statistically significant decline in scores as compared to Conventional group (0.83 ± 0.37), p = 0.043. Meanwhile, the oral hygiene scores in the PAIR group and Conventional group were 1.22 ± 0.14 and 1.94 ± 0.15, respectively (p < 0.05). A significant improvement in oral hygiene practices was observed in the PAIR group. Incorporating the PAIR technique resulted in significant progress in child cognitive ability and adaptive behavior, which reduced gingival scores and improved oral hygiene scores, consequently improving oral hygiene practices among children with ASD.
