title: Mineralization defects in deciduous teeth of low birthweight infants.
abstract: A group of 91 children with birthweights below 2000 g and 48 healthy full-term children, reference group, were examined for mineralization disturbances of the enamel of deciduous teeth. Perinatal data were collected retrospectively from obstetric and neonatal records. Within the low birthweight group, children with enamel hypoplasia had on the 5% level a significantly lower intake of breast milk during the first week of life than children without disturbances. The only perinatal complication associated with development of mineralization defects was IRDS. Infants with IRDS, however, had a significantly lower intake of breast milk during the first week of life than low birthweight without IRDS. A low frequency of enamel defects was found in the growth-retarded sub-group of the low birthweight infants. These infants had a significantly higher intake of breast milk during the first week compared to the AGA-group. A seasonal variation was found, with the highest prevalence of mineralization disturbances in infants born during winter months. It is concluded that the occurrence of mineralization defects of the deciduous teeth in LBW infants seems to be dependent upon the amount of breast milk given during the early neonatal period and also possibly in which season of the year they are born.
