Background and Aim: Tooth eruption is a multifaceted physiological process, which can be delayed by factors such as malnutrition. This study aimed to compare the serum levels of vitamin D and calcium in infants with a longer than normal eruption time of the first deciduous tooth with the control group (normal eruption).

Materials and Methods: In this case-control study, serum levels of vitamin D in 61 children with a mean age of normal dental eruption in Iranian children (8 months and less) were compared with 61 children with eruption age of more than 8 months. The children were matched in terms of age, sex, place of birth and residence, age of birth, birth weight, and other eruption-related items. Student's t-test, analysis of variance (ANOVA), and chi-square test were used for statistical analysis.

Results: The first erupted tooth in all infants was the mandibular incisor. The mean serum level of vitamin D was 38.1±24.1 ng/ml in infants with eruption age of 8 months or less and 40.0±21.5 ng/ml in the group of eruption age over 8 months (P=0.63). Serum calcium level was 10.03±0.55 mg/dl in the first group and 9.92±0.57 mg/dl in the second group (P=0.28). There was no significant relationship between gender, maternal education, A+D supplementation, infant nutrition (breast milk, formula, and combination), and different levels of vitamin D (deficient, inadequate, adequate, and toxic) with the average age of eruption of the first deciduous tooth (P>0.05).

Conclusion: It seems that serum vitamin D and calcium levels in this age group do not affect the eruption time of deciduous teeth.
