Use of Visual Pedagogy to Help Children with ASDs Facing the First Dental Examination: A Randomized Controlled Trial.
A quick video model gives a small head start on dental steps for kids with autism, but extra supports are needed for real cooperation.
01Research in Context
What this study did
Moya et al. (2022) tested two kinds of visual pedagogy for kids with autism who were about to get their first dental exam. One group watched a short video that showed each step of the exam. The other group looked at a photo storyboard of the same steps.
The team then counted how many early steps each child could finish, like sitting in the chair or opening wide. They also rated overall cooperation.
What they found
Kids who saw the video completed a few more early steps than kids who saw the photos. The difference was small but real. Cooperation scores were almost the same in both groups.
In plain words, the video gave a tiny boost, but it did not turn a scared child into a calm one.
How this fits with other research
Mulder et al. (2020) found bigger gains when they used video modeling to teach tooth-brushing at home. Their kids moved from poor to good brushing in weeks. The dental office setting in S et al. may explain why the effect shrank.
Pui Cai et al. (2024) pooled 18 dental studies and saw only small, uneven gains across all behavioral tricks. Their wide view matches the small video edge seen here.
Esposito et al. (2024) bundled video with parent coaching and tripled independent brushing steps. Adding more parts, not just switching the visual, may be the key step the current trial missed.
Why it matters
If you prep kids for new medical tasks, a short video beats a photo board, but do not expect miracles. Pair the clip with gradual exposure, parent priming, and strong reinforcement. One minute of video is cheap, so keep it in your toolbox—just add more supports if you need big change.

03Original abstract
Autism Spectrum Disorders (ASDs) are neurodevelopmental disorders that don't have a direct effect on oral health, but severe difficulties in oral hygiene and dental procedures expose people with ASDs to an increased risk of oral diseases. This RCT aimed to evaluate which pedagogical tool was the best to prepare children with ASDs for their first dental examination, either video or photo aids. Two different criteria were used to evaluate their efficacy: the achieved steps into which the procedure was divided (<i>n</i> = 8), and the level of cooperation according to the Frankl Behavioral Scale. One hundred-thirteen subjects were randomly assigned to the two groups and 84 subjects completed the trial (Video group <i>n</i> = 41; Photo group <i>n</i> = 43). A predictive model for the achievement of the Preliminary (1-4) or Dental (4-8) steps was performed using a multivariate logistic regression procedure. Children in the Video group achieved more steps, but the comparison between groups was statistically significant only for the Preliminary steps (<i>p</i> = 0.04). The percentage of subjects judged as cooperating was similar in the two groups. The results of this study underline that behavioural intervention should be used as an effective strategy to prepare subjects with ASDs for a dental examination.
