An eruption pattern of deciduous teeth in children born with fetal macrosomia during the first year of life

Abstract

The paper aims at studying the effect of body overweight at birth on the dental health of 482 children in the Kharkiv City (Ukraine) during their first year of life over the 2001 and 2013 interval. The macrosomia set is comprised of the medical records of the children born with fetal macrosomia, and the normosimia set of the medical records of the children born with weight and height that correspond to the gestation age. The gestation age of all children is 37 to 42 weeks'. To determine the average time of first tooth eruption and deciduous teeth growth rate for each of the sets understudy, we have used the hypothesis about a linear dependence between the number of erupted teeth and the age of the child. Processing statistical data is performed applying the multiple linear regression analysis. The reasons for macrosomia in the children are examined. The number of pregnancies and deliveries influence the likelihood of having a child with fetal macrosomia. A greater likelihood of having a child with fetal macrosomia in the older parents is not found. The correlation between the states of a child at birth (macrosomia/normosimia) and terms of deciduous tooth eruption (the delayed/timely/early eruption) expressed in a number of teeth at the age of one year is determined. The difference in the teeth growth rate between the boys and girls within the both sets are insignificant. The children born with macrosomia have a lower rate (approximately 0.1 tooth per month) of teeth growth and a greater spread in the number of teeth that erupt by a certain age.
