Abstract
Background
Dental caries in children is a major public health problem worldwide, with a multitude of determinants acting upon children to different degrees in different communities. The objective of this study was to determine maternal, environmental, and intraoral indicators of dental caries experience in a sample of 6- to 7-y-old children in South East Queensland, Australia.
Methods:
A total of 174 mother-child dyads were recruited for this cross-sectional study from the Griffith University Environments for Healthy Living birth cohort study. Maternal education, employment status, and prepregnancy body mass index were maternal indicators, and annual household income was taken as a proxy for environmental indicators. These were collected as baseline data of the study. Clinical data on children’s dental caries experience, saliva characteristics of buffering capacity, stimulated flow rate, and colony-forming units per milliliter of salivary mutans streptococci were collected for the oral health substudy. Univariate analysis was performed with 1-way analysis of variance and chi-square tests. Caries experience was the outcome, which was classified into 4 categories based on the number of carious tooth surfaces. Ordinal logistic regression was used to explore the association of risk indicators with caries experience.
Results:
Age (P = 0.021), low salivary buffering capacity (P = 0.001), reduced levels of salivary flow rate (P = 0.011), past caries experience (P = 0.001), low annual household income; <$30,000 (P = 0.050) and <$60,000 (P = 0.033) and maternal employment status (P = 0.043) were associated with high levels of dental caries.
Conclusion
These data support the evidence of associations between maternal, environmental, and children’s intraoral characteristics and caries experience among children in a typical Western industrialized country. All of these need to be considered in preventative strategies within families and communities.
Knowledge Transfer Statement:
The results of this study can be used by clinicians, epidemiologists, and policy makers to identify children who are at risk of developing dental caries. With consideration of costs for treatment for the disease, this information could be used to plan cost-effective and patient-centered preventive care.
