The effect of culturally adapted oral hygiene dental visual aids on plaque removal in autistic children: A randomized clinical trial.

Aljubour et al. (2026) · Research in developmental disabilities 2026
★ The Verdict

Trade generic dental flash cards for culturally matched ones and watch plaque drop in autistic kids.

✓ Read this if BCBAs running home or clinic programs that include tooth-brushing training.
✗ Skip if Practitioners who already work only with families who share the majority culture.

01Research in Context

01

What this study did

The team ran a six-month randomized trial with autistic children.

Half the kids got standard dental picture cards. The other half got cards that matched local Saudi clothes, food, and faces.

All families kept brushing teeth twice a day. Researchers checked plaque every month.

02

What they found

Kids who saw the local-culture cards had less plaque at every visit.

The difference grew bigger each month.

Standard cards helped a little, but the adapted cards won.

03

How this fits with other research

Kammer et al. (2025) showed most dental visits fail because staff lack training and parents feel ignored. This study answers that call by giving parents a culturally tuned tool they can use at home.

McMullen et al. (2017) used prediction plus desensitization to calm one boy in the clinic. The new study moves upstream: it teaches daily brushing skills before anxiety ever starts.

Johnson et al. (2021) proved that culturally tailored parent training boosts advocacy. Here, the same idea is applied to oral care—when pictures look like the child’s world, parents use them more and kids learn faster.

Why it matters

You can swap your current tooth-brushing visuals for culture-matched ones tomorrow. No extra cost, no extra time, just better plaque control. If you serve Muslim or Arab families, ask them to pick photos that feel familiar and make new cards. Expect cleaner teeth and fewer meltdowns at the sink.

Ask the parent to email you three photos of the child’s favorite local foods or family members; paste them onto your current brushing sequence sheet and use it in the next session.

03Original abstract

BACKGROUND: Culturally tailored visual aids are a vital educational resource for facilitating skill acquisition in children with Autism Spectrum Disorder (ASD). This study evaluates the effectiveness of a culturally adapted dental visual aid, developed by Aljubour, in enhancing the oral hygiene of children with ASD over a six-month follow-up period. METHODOLOGY: A longitudinal, blinded, randomized, and controlled clinical trial was conducted over six months. Participants were allocated into two groups: Group I received the Aljubour culturally adapted dental visual aids, while Group II received conventional dental visual aids. Oral hygiene status was assessed using the Silness and Löe plaque index. RESULTS: Although the reduction in mean plaque index following six months of using the culturally adapted visual aids was not statistically significant (P = 0.120), a significant difference was observed between the two study groups (P = 0.002). CONCLUSION: The findings indicate that children with ASD who utilized the Aljubour culturally adapted dental visual aids demonstrated a significant improvement in oral hygiene status compared to those who used conventional dental visual aids after a six-month evaluation period.
