The index dmft (Decayed Missed Filled Teeth) in primary teeth D and E is equaled to 2.46 and prevalence of dental caries E and D were estimated 63.4%. There is significant relationship between decay of teeth D and E and father education (Pvalue<0.001) and mother education (Pvalue 0.001) children age (Pvalue<0.001) locality of children whether they live in rural or urban regions (Pvalue 0.001) economic condition of families (P value<0.001) and social status (Pvalue<0.001) with number of decay teeth. The results imply on high prevalence of teeth caries among the children molar covered by Shemiranat health center so that the number of teeth without caries is far from the global measures and WHO.
