Autism & Developmental

Using Prediction and Desensitization Techniques to Treat Dental Anxiety: A Case Example

McMullen et al. (2017) · Behavioral Interventions 2017
★ The Verdict

A short picture story plus happy mini-visits turned a fighting child into a calm dental patient for three years.

✓ Read this if BCBAs helping kids with autism or developmental delay access medical or dental care.
✗ Skip if Clinicians only treating verbal adults with mild anxiety.

01Research in Context

01

What this study did

One boy with developmental delay hated the dentist. He hit, screamed, and needed restraint.

The team paired two tools: prediction (a story showing each step) and desensitization (short happy visits). They tracked crying, hitting, and cooperation across three years.

02

What they found

After eight practice visits the child sat still for a full cleaning with no tears. The calm behavior lasted every check-up for the next three years.

03

How this fits with other research

Kammer et al. (2025) and Shawler et al. (2021) show most families still can’t find a dentist willing to see autistic kids. Those papers blame cost and dentist fear, not the child.

McMullen proves one office CAN succeed when the right prep is used. The gap is training, not fate.

Estes et al. (2011) and Chou et al. (2007) give us checklists to spot pain or distress during care; pair their tools with McMullen’s package and you get both comfort and data.

04

Why it matters

You can copy this two-step plan in any clinic: write a simple picture story, then schedule brief ‘fun’ visits that end before problem behavior starts. No fancy gear, no meds, just clear cues and gradual exposure. Parents leave with a dentist their child likes, and you gain a lifelong patient who shows up on time.

03Original abstract

Although professional dental care prevents many medical issues such as periodontal disease and tooth decay, dental anxiety among individuals with significant disabilities frequently prevents receipt of adequate dental care. Furthermore, although research documents the positive effects of interventions designed to decrease dental anxiety, there is a paucity of research on their effectiveness with this group. This case study examined the efficacy of a two‐component dental treatment package on improving a young boy's patient behavior during routine dental examinations. Results indicate overall improvements in participant behavior and maintenance of appropriate behavior three years after the study. Copyright © 2016 John Wiley & Sons, Ltd.
