Results. 76 % of the studied children have already experienced dental caries at the age of 4-5 years (1046 children). The mean dmft score was found to be 2.46 while the other 24 % of children were caries-free.There was no significant difference in caries prevalence between boys and girls (77.2 % versus 74.6%). Children of highly educated and college graduatedmothers were found to havemore fillings (restored teeth) in comparison to those who belong to mothers who did not finish their secondary (high school) education. Conclusion.The number of caries-free children in northern Palestine is still far from numbers found in developed countries.
