Abstract

Introduction: Eruption of first primary teeth is a normal physiological process. Antenatal nutritional deficiency and prenatal and neonatal factors play an important role in eruption of primary teeth. Neonatal factors, such as gestational age (GA), degree of prematurity, severity of neonatal illness, and birth weight are primarily related to eruption of primary teeth. The relation between neonatal factors and the timing of eruption of primary teeth has not been studied prospectively among Indian preterm infants. Aims: To evaluate the influence of neonatal factors on the eruption of primary teeth in children born preterm. Materials and methods: A prospective longitudinal cohort study design was adopted. A total of 150 subjects were recruited by simple random sampling. Each child was followed up from birth up to 36 months. Intraoral examination was done and the teeth present in each visit were recorded. Data were statistically analyzed and interpreted. Statistical analysis used: Descriptive statistics, t-tests for independent sample, and Pearson's chi-squared tests were applied. Tooth showing statistically significant difference in mean age of eruption between term and preterm categories was studied for the effect of maternal and neonatal characteristics on eruption using multivariate regression analysis. Results: The mandibular central incisor was the first tooth to erupt. Significant determinant of eruption of mandibular incisor in term children was found to be parity, weight for GA, and complementary feeding, whereas for preterm children, significant determinants were parity, birth weight birth length, weight for GA, and complementary feeding. Conclusion: Neonatal factors, such as birth weight, birth length, weight for GA, and introduction of complementary feeding have a strong significant association with the eruption of primary teeth. Clinical significance: The findings of this study will guide in the preventive management of oral health in preterm children.
