Impact of untreated dental caries on oral health-related quality of life of children with special health care needs

Abstract

Abstract: The oral health status of children with special health care needs (SHCN) can affect their quality of life wich domains of the Brazilian version of the Early Childohood Oral Health Impact Scale (B-ECOHIS). A cross-sectional study was conducted in children with SHCN (aged 1 to 9 years), who underwent an oral examination for the assessment of dental caries severity. Parents/caregivers answered two questionnaires, one on oral health-related quality of life (OHRQoL) - B-ECOHIS, and one on socioeconomic characteristics. Statistical analyses were performed using the Kolmogorov-Smirnov test, Mann-Whitney U-test, Poisson regression, Point-biserial correlation coefficient, and Cronbach's alpha. A total of 128 children participated in the study and OHRQoL was affected in 68.75% of them. The function domain in the Child Impact Section (CIS) had a higher mean value. Caries severity was associated with worse quality of life (p=0.001). Severe dental caries was associated with a negative impact on the OHRQoL of disabled children and of their families. The impact of untreated dental caries and severity of dental caries was associated with the CIS domains (except for the self-image/social interaction domain).
