36 months. The prevalence of dental caries was 34.2% at 24 months (n = 206) and
68.5% at 36 months of age (n = 409). In bivariate analysis, higher education of the mother,
lower household income, bottle feeding of the infant, frequent sweet candy consumptions,
and using rain or well water as drinking water were associated with dental caries
increment, while in multivariate conditional logistic regression analysis lower household
income, higher education of the mother, and using rain or well water as drinking water
remained associated with dental caries increment. In conclusion, a very significant increase
in caries development was observed, and oral health may be influenced by
sociobehavioural risk factors.
