Socioeconomic factors in relation to dental caries among children aged 5–14 years: a cross-national comparative study using secondary data analyses

This ecological study provides valuable insights into the global patterns of dental caries in children aged 5-14 years and their associations with selected socioeconomic indicators. Our results reveal significant correlations of dental caries with income level, water fluoridation coverage, and parental education. However, these associations should be interpreted with caution due to the ecological nature of the data and several important limitations.
