Association between oral care challenges and sensory over-responsivity in children with Down syndrome

Abstract

Background: Sensory over-responsivity has been linked to oral care challenges in children with special healthcare needs. Parents of children with Down syndrome (cDS) have reported sensory over-responsivity in their children, but the link between this and oral care difficulties has not been explored.

Aim: To investigate the relationship between sensory over-responsivity and oral care challenges in cDS.

Design: An online survey examined parent-reported responses describing the oral care of their cDS (5-14 years; n = 367). Children were categorized as either sensory over-responders (SORs) or sensory not over-responders (SNORs). Chi-square analyses tested associations between groups (SORs vs. SNORs) and dichotomous oral care variables.

Results: More parents of SOR children than of SNOR reported that child behavior (SOR:86%, SNOR:77%; p < .05) and sensory sensitivities (SOR:34%, SNOR:18%; p < .001) make dental care challenging, their child complains about ≥3 types of sensory stimuli encountered during care (SOR:39%, SNOR:28%; p = .04), their dentist is specialized in treating children with special healthcare needs (SOR:45%, SNOR:33%; p = .03), and their child requires full assistance to brush teeth (SOR:41%, SNOR:28%; p = .008). No intergroup differences were found in items examining parent-reported child oral health or care access.

Conclusions: Parents of SOR children reported greater challenges than parents of SNOR children at the dentist's office and in the home, including challenging behaviors and sensory sensitivities.
