Methods: We estimated the prevalence of developmental disorders of the stomatognathic system in the primary dentition of preschool children at five years of age.

Maternal 25(OH)D may influence the primary dentition, and improving vitamin D status in pregnant women might affect ECC rates in their infants.

Ninety-three percent of subjects had caries in primary dentition and the mean number of decayed teeth in primary dentition was 7.54 ±4.82.
