Caretaker's caries experience and its association with early childhood caries and children's oral health-related quality of life: A prospective two-generation study.

Objectives: The first objective of this study is to examine the association between caretakers’ caries experience and caries experience of their children. Second, to investigate whether children’s and caretaker’s caries experience is associated with oral health-related quality of life (OHRQoL) of children and their families. Methods:This study is based on the prenatal recruitment interviews and the 5-year follow-up of 417 caretaker–children pairs from the Ugandan site of the PROMISE-EBF trial conducted in Mbale, Eastern Uganda. Face-to-face interviews were conducted with caretakers at the household level. Caries experience of caretakers (DMFT >0) and children (dmft >0) were assessed in accordance with the criteria of the World Health Organization. OHRQoL was assessed using an abbreviated version of the Early Childhood Oral Health Impact Scale (ECOHIS). Results:Adjusted negative binomial regression analysis revealed that caretaker’s caries experience was positively associated with early childhood caries of their offspring (IRR 2.0, 95% confidence interval (CI) 1.3–3.0). Children’s caries experience (IRR 1.8, 95% CI 1.2–3.0), but not caries experience of caretakers, was associated with worse OHRQoL of children and their families. Caretakers who perceived good child oral health were less likely to report OHRQoL impacts (IRR 0.20, 95% CI 0.12–0.35). Conclusion:Improving caretaker’s caries experience and her perception of child’s oral health status could improve children’s caries experience and the OHRQoL of children and family. Such knowledge is important and should inform public oral health programs for young children. [ABSTRACT FROM PUBLISHER]
