Table 4.

Multivariate logistic regression of the predictors of a high caries experience* in the permanent teeth of Lithuanian 5–6-year-olds.

Predictor	High DF-S, Odds Ratio (95% CI)
High % dmfs *	4.2 (2.7–6.8)
Age, years	2.7 (1.3–5.4)
Self-reported tooth brushing frequency	2.5 (1.5–4.3)
Nagelkerke R Square = 0.3; Overall Percentage = 81.2

* A high caries experience in primary and in permanent dentition was defined as belonging to the upper tertile (dmfs > 21; DF-S > 2) of the distribution of dmfs and of DF-S values, respectively.
