234 - Desensitization for Dental and Medical Care in Intellectual Developmental Disorders

Abstract:

Purpose:
To evaluate desensitization as a non-pharmacological intervention for reducing anxiety, improving cooperation, facilitating dental and medical care in children with intellectual developmental disorder (IDD), compared with traditional management approaches.

Methods:
A systematic review was conducted of peer-reviewed studies published between 2004 and 2024 examining behavioral interventions for children and adolescents under 21 years of age with neurodevelopmental disorders, including IDD and autism spectrum disorder (ASD), within the United States. Studies were identified using PubMed, Embase, Elsevier, and Cochrane databases. Included studies implemented structured, non-pharmacological behavioral strategies to improve tolerance of medical and dental procedures. Common interventions included graduated exposure and desensitization, task analysis, positive reinforcement, visual supports, and systematic fading of prompting. Interventions were delivered in clinical, educational, or home settings by trained professionals, frequently involving caregivers to individualize pacing and promote generalization. Outcomes were measured through direct observation and video recording, assessing compliance, procedural completion, problem behaviors, distress, and maintenance of effects.Ethical standards were upheld across studies, including informed consent and ongoing monitoring of participant well-being.

Results:
Desensitization-based interventions consistently improved compliance, reduced anxiety, increased tolerance for dental examinations, needle procedures, and pill swallowing. Multicomponent approaches combining exposure, reinforcement, visual supports, and caregiver involvement demonstrated the greatest and most durable improvements, with generalization across settings. Minimal adverse effects were reported, non-pharmacological interventions reduced reliance on sedation and physical restraint.

Conclusions:
Desensitization and related behavioral strategies effectively enhance cooperation and access to dental and medical care for children with IDD. Integrating evidence-based interventions and caregiver involvement supports health outcomes.
