Chen KJ, et al. – A cross–sectional study was conducted to examine dental caries status and its associated factors among 5–year–old children in Hong Kong. Researchers reported that dental caries was prevalent among 5–year–old Hong Kong children. They observed that most of the decayed teeth were untreated. They found that the caries prevalence of the children was related to their frequency of sugary snack intake, dental attendance and socio–economic background.
