Oral health-related quality of life in children and adolescent with autism spectrum disorders and neurotypical peers: a nested case-control questionnaire survey

Purpose: Oral health-related quality of life (OHRQoL) of children with autism following an oral preventive regimen (ASDsP) was compared to that of children with autism without a preventive regimen (ASDsNP) and of neurotypical peers (NT).

Methods: An online survey was carried out using the Parental/Caregiver Perception Questionnaire (P-CPQ) and the Family Impact Scale (FIS). Scores were assigned to items, with the total score ranging from 0 to 120 (worst QoL). The median scores were compared amongst groups using the Mann-Whitney and Kruskal-Wallis tests. A multivariate linear regression assessed the relationship between questionnaire scores and demographical variables.

Results: Overall, 168 questionnaires from the ASDsP and the ASDsNP groups, respectively, and 336 from the NT group were selected ASDsP compared to ASDsNP showed lower P-CPQ Emotional wellbeing, FIS Emotion (p < 0.01) and Conflict (p < 0.05), and FIS total score (p < 0.01). In addition, they were less nervous (p < 0.05), shy (p < 0.01), with better sleep (p < 0.05), and with happier parents (p < 0.01). Compared to NT, ASDsP showed higher P-CPQ + FIS, P-CPQ, and FIS total scores (p < 0.01) and P-CPQ Functional limitation, Social wellbeing (p < 0.01), Emotional wellbeing (p < 0.05), and FIS Activity, Emotion and Conflict (p < 0.01).

Conclusion: The preventive regimen reduces parental stress, improving the quality of life of children and families.
