Children with Autism Spectrum Disorder Are Able to Maintain Dental Skills: A Two-Year Case Review of Desensitization Treatment.

Purpose: The purposes of this study of children with autism spectrum disorder (ASD), who had successfully accepted a dental examination seated in a dental chair following desensitization interventions, were to: (1) determine if ability to accept an examination was maintained two years following initial success; (2) quantify new dental skills acquired; and (3) analyze the use of advanced behavior guidance techniques.

Methods

This retrospective two-year case series included 138 ASD children. Data were obtained from dental records. Descriptive statistics were calculated, and Fisher's exact test was used for comparisons of interest.

Results

Most children (92 percent) maintained the ability to receive minimum threshold examinations once the initial exam had been achieved. New basic dental skills attained by most children included receiving toothbrush prophylaxis (83 percent) and accepting fluoride varnish (77 percent). Few children required oral sedation or protective stabilization, but 22 percent received general anesthesia.

Conclusions

Most children with autism spectrum disorder who learned to accept an examination maintained that skill over time, and many accepted toothbrush prophylaxis and fluoride varnish. Sensory-invasive skills, such as radiographs and rubber cup prophylaxis, were acquired with lower frequency. Therefore, when treating ASD patients, it is important to consider that some will require advanced behavior guidance techniques. (Pediatr Dent 2019;41(5):397-403).
