Background: Vitamin D insufficiency is a public reason of rickets, a situation that distresses bone development in children and that can have severe dental obstacles. VDD rickets happens utmost usually through infancy, beginning in the primary months of life. The absence of vitamin D through gestation can cause enamel hypoplasia of deciduous teeth. Deficiency over premature babyhood can upset permanent teeth and resulting caries can sometimes hint to tooth damage at a young age. Aim of study: To reveal the effect of nutritional rickets on the occurrence of dental caries and enamel defect in children, also to estimate the influence of nutritional rickets by feeding types and area of residency. Materials and methods: Total 30 children with vitamin D nutritional deficiency rickets with an age range from 1.5 years to 3.5 years of both genders were compared with 30 healthy children as a control group. Dentition status was measured according to WHO 1997, feeding type and area of residence were recorded while enamel defect was registered according to enamel defect index WHO 1997. Results: Caries experience represented by dmfs was significantly higher among control group compared to study group, while enamel hypoplasia was higher in the study group than the control group. Exclusive breastfeeding children are more prone to nutritional rickets than mixed and bottle feeding. Rural area children were at high risk to nutritional rickets. Conclusion: There is an obvious effect of nutritional rickets on caries experience and enamel hypoplasia. The 25-hydroxyvitamin D was lower in exclusive breastfeeding children.
