Parental psychosocial factors and children's oral health-related quality of life: Data from a caries prevention study with phone-based support.

backgroundCaries burden in children disproportionately affects minority and socioeconomically disadvantaged populations. Severe early childhood caries requiring general anesthesia (GA) is a significant concern, with high caries relapse rates in subsequent years.

aimTo examine associations between parental psychosocial factors, children's caries burden, and oral health-related quality of life (OHRQoL), including group differences, following a phone-based parental support intervention for children treated under GA for severe Early Childhood Caries (ECC).

methodsData were collected during a randomized controlled trial examining a phone-based parental support program. Parental stress was assessed using the Swedish Parenthood Stress Questionnaire (SPSQ), dental fear was measured with the Corah Dental Anxiety Scale (CDAS), and dental attitudes were evaluated using the Dental Beliefs Survey (DBS-R). Children's OHRQoL was assessed using the Parental-Caregivers Perception Questionnaire (P-CPQ) and the Family Impact Scale (FIS). The Total Observed Caries Experience index was used to calculate the child's cumulative caries burden. Unadjusted analyses were performed using t-tests, with effect sizes calculated as Cohen's d. A two-step path analysis examined how parental factors, intervention, and baseline caries influenced caries burden at a one-year follow-up, while also assessing caries burdens impact on children's well-being.

resultsAt the one-year follow-up, the intervention group demonstrated significantly improved OHRQoL with lower mean scores on the P-CPQ and FIS compared to the control group, indicating fewer oral health issues and less impact on family life. No statistical differences were found in parental stress, dental fears, or dental beliefs between groups. Path analysis identified baseline caries and treatment group as significant predictors of caries burden, while intervention group predicted better OHRQoL outcomes. The model explained 86.2% of caries burden variance and 12.9% of OHRQoL variance.

conclusionA phone-based parental support program significantly improved children's OHRQoL, even with a higher caries burden in the intervention group at the one-year follow-up. Parental stress, dental fears, and attitudes showed no differences and did not predict caries burden. Preventing early childhood caries in high-risk groups remains challenging, highlighting the importance of preventive initiatives that empower parents and foster collaboration with key stakeholders to reduce severe ECC.
