In a recent study, researchers have noted that the underlying socioeconomic Inequalities explained the association between prevalence and severity of dental caries in primary dentition and source of drinking water.

The objective of the study, published in the Journal of Dentistry, was to evaluate the association between source of drinking water and dental caries at age 5 and to test whether socioeconomic conditions act as confounding factors in such association.

The study was carried out in a sub-sample of the 2004 Pelotas Birth Cohort, which comprised the application of a questionnaire and clinical oral examination. The exposure was the source of drinking water, collected through a question to the primary caregiver. The outcome was dental caries in the primary dentition. Socioeconomic indicators (family income and maternal education) were identified as potential confounding factors.

1,084 children were evaluated and had complete information in all variables.

--Dental caries experience was observed in 48.7% of the children, with a mean of 1.9 decayed, missing, or filled teeth.

--Most children consumed water from the public water supply, and a socio-economic pattern was observed, with children from lower-income more likely to drink water from the public supply.

--In crude analysis, children who consumed bottled water had a lower risk of decayed teeth, the lower experience of dental caries, and less severe disease. No associations were observed after adjustments for socioeconomic conditions.

Overall, underlying socioeconomic inequalities explained the association between prevalence and severity of dental caries in primary dentition and source of drinking water.
