Oral health status and dental treatment needs in children with autism spectrum disorder

Objective: To evaluate oral health care practices, health status, and dental treatment needs in children with Autism Spectrum Disorder (ASD). Methods: This cross-sectional study included 96 children diagnosed with ASD per the DSM-V criteria and 96 typically developing healthy children. The WHO form assessed oral health status and dental treatment needs. Results: Over 50 % of ASD children had mild/moderate autism, 35.4 % had severe autism, and 13.5 % had autistic traits. ASD children experienced more toothbrushing difficulties compared to non-ASD children. Based on Nyvad's criteria and decayed/filled teeth (dft) index, non-ASD children had higher caries prevalence than ASD children, indicating less need for restorative treatments in the ASD group. However, ASD children had poorer plaque scores than non-ASD children. A significantly higher percentage of ASD children exhibited harmful oral behaviors, including mouth breathing, lip biting, bruxism, nail biting, object biting, and self-injury (p
