Table 3.
Association between social gradient (from best to worst) and caries levels (enamel lesions, pre-cavitated lesions, cavitated lesions) and total caries prevalence adjusted by areas of living

OR Odds Ratio, 95%CI 95% Confidence Interval and the Mantel Haenszel trend of odds were calculated
For enamel lesions and pre-cavitated lesions very few observations were present so the association between Social Gradient was not run
