Dental desensitization by dentists and occupational therapists for autistic adults: A pilot study

The aim of this pilot study was to assess the efficacy of a desensitization program developed by dentists and occupational therapists, targeted at autistic adults, to encourage their cooperation in the dental setting. The study group consisted of 18 individuals with autism (10 men and 8 women, aged 18-45 years). The patients underwent a baseline examination, after which they were progressively exposed to oral examination maneuvers and ultimately dental procedures. To this end, the participants engaged in a weekly desensitization session performed by an occupational therapist and a monthly assessment session by a dentist applying the Frankl scale, for a maximum period of 30 weeks. During the first session, 44% of the participants completed all oral examination procedures, reaching 94% by the fourth visit and 100% by the seventh visit. None of the participants completed a simple dental treatment up to the third session, subsequently increasing the percentage progressively until reaching a maximum of 61% in the seventh visit. In conclusion, a dental desensitization program implemented by dentists and occupational therapists could help in performing oral examinations and simple therapeutic procedures for a considerable percentage of adults with autism, without having to resort to pharmacological behavioral control techniques. Lay abstract Managing patients with autism in the dental clinic often requires resorting to pharmacological behavioral control techniques, including general anesthesia. References in the literature to desensitization programs are scarce and focus on training children with autism to undergo oral examinations and preventive procedures. This study shows that a dental desensitization program implemented by dentists and occupational therapists could help in performing not only oral examinations but also simple dental therapeutic procedures for a considerable percentage of adults with autism, without using a pharmacological intervention (sedation or general anesthesia).
