Abstract: (41 Views)
Background and Aim: Primary tooth eruption is an important indicator of child development. This study examined the effect of delivery type (vaginal vs. cesarean) on the age of eruption of the first primary tooth in children residing in Kerman.
Materials and Methods: This cross-sectional study included 221 children, comprising 108 born vaginally and 113 born by cesarean delivery. Inclusion criteria included healthy infants with normal birth weight and no systemic disorders. Data were collected through parental questionnaires and medical records and analyzed using SPSS software (version 27). Statistical tests included Chi-square, independent t-test, Mann-Whitney, and Spearman correlation. A level of 0.05 was considered significant.
Results: The mean age of eruption of the first primary tooth in the cesarean group (8.15 months) was slightly higher than that in the vaginal birth group (7.86 months); however, this difference was not statistically significant (P = 0.23). Children born via vaginal delivery were significantly more likely to be breastfed (P = 0.004). The age of eruption was not significantly correlated with birth weight and height in both birth types.
Conclusion: The results of this study showed that the delivery type does not have a significant effect on the timing of the eruption of the first deciduous tooth in children. Overall, it seems that other factors, such as nutrition and individual characteristics of the child, including gender and birth weight, have a greater effect on the timing of tooth eruption.
