Dietary Sugar Exposure and Oral Health Status in Children with Autism Spectrum Disorder: A Case-control Study.

This case-control study compared dietary sugar exposure and oral health status between children with and without Autism Spectrum Disorder (ASD), aged 5-12 years (n = 136, each). Data regarding socio-demographics, child's oral hygiene practices and behavior, diet-related behavior, oral habits and dental trauma were obtained. Child's diet on the previous day was recorded using 24-h recall method and sugar exposure was calculated using Dental Diet Diary (D3) mobile application. Oral Hygiene Index-Simplified (OHI-S), deft and DMFT were recorded. Results showed no significant differences in sugar exposure, deft and DMFT between the groups. Although oral hygiene practices were significantly better in children with ASD, their OHI-S was significantly worse. Significantly more children with ASD reported mouth-breathing, bruxism and self-injurious habits.
