Enamel Defects in the Primary Dentition of Preterm and Full Term Children
ABSTRACT This study compared enamel defects in children born prematurely and at term.
96 children born at term (G1), and with 96 children born prematurely (G2) were studied.
A higher prevalence of enamel defects was found in the premature group, with a predominance of hypoplasia. In G1, 64 teeth displayed enamel defects (51 opacities and 13 hypoplasias). In G2, 110 defective teeth were found, (29 opacities and 81 hypoplasias). A significant correlation was found between very low birth weight (VLBW) and the presence of these defects (p < or = 0.001). The teeth most affected were the incisors, canines and molars.
Prematurity, in conjunction with other factors, can predispose children to enamel defects.
