Abstract
The eruption process is under strong genetic control, external environmental factors also significantly contribute to this process. Therefore the present study was undertaken to identify the influence of birth characteristics and feeding practices on the eruption of the first primary tooth among healthy children in Pune, Maharashtra, India. The study was undertaken among 200 children aged 3-24 months. Children with any underlying conditions, those not accompanied by their mother and with neonatal teeth/natal teeth were excluded. The birth weight, gestational age, and type of delivery were obtained from medical records of the child. Data on feeding practices and the age of eruption of the first primary tooth was recorded after a structured interview of the mother followed by oral examination of the child. Gestational age was categorized into >37 weeks and <37 weeks, birth weight was divided into three groups-<1500, 1500-2500, and >2500 gm and four groups according to feeding practice during the first 6 months of life (exclusively breastfed, exclusively bottle fed, combination of breastfeeding and bottle feeding, and spoon-feeding). The mean age of eruption in the study population was 9.17 months. A9.05 months in males and 9.44 in females. A statistically significant correlation was noted with gestational age, birth weight, and feeding practices. Infants with a gestational age of >37 weeks, higher birth weight and those who were exclusively breastfed for the first 6 months had an earlier eruption of first primary teeth. External factors seem to influence the eruption of the primary tooth. More longitudinal studies with larger sample sizes and matching confounders are needed to clearly understand the factors affecting the primary tooth eruption.
