Association between a child's caries experience and the mother's perception of her child's oral health status

Background. Mothers play a primary role in the health of their children. This role may be of particular importance for children in Appalachia who have increased caries relative to children in other regions of the United States. The authors examined the degree to which a child's caries experience was in concordance with the mother's perception of the health of her child's teeth, and how concordance varied by sociodemographic factors. Methods. The authors obtained cross-sectional data on mother-child dyads with children younger than 6 years through the Center for Oral Health Research in Appalachia study. They interviewed and clinically examined a community-based sample of 815 mother-child dyads from Pennsylvania and West Virginia. They used an unadjusted zero-inflated negative binomial model to estimate the association between a mother's perception of her child's oral health status and her child's caries. The authors compared sociodemographic factors between concordant and nonconcordant mother-child dyads using chi(2) tests. Results. The mother's perception of her child's oral health status was associated with the child's caries experience (P < .001). Two-thirds of mother-child dyads showed concordance between the mother's perception of her child's oral health status and the child's caries experience (n = 522, 64%). Concordance was associated with younger child age and the child having dental insurance (P < .01). Conclusions and Practical Implications. On average, mothers accurately perceived their child's caries experience. This accuracy was higher for younger children and children with dental insurance. The mother's awareness of her child's oral health status could be used to develop effective prevention and treatment strategies, particularly for young children vulnerable to caries.
