ABSTRACT
AIM: This study compared enamel defects in children born prematurely and at term. METHOD: 96 children born at term (G1), and with 96 children born prematurely (G2) were studied. RESULTS: 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. CONCLUSION: Prematurity, in conjunction with other factors, can predispose children to enamel defects.

This study aimed to validate clinical analysis of 20 pediatric dentists on occlusal groove-fossa-system of molar depth comparing to Cone-beam tomography. The 48 sound third molars were visually classified from the shallowest to the deepest. Images were taken from the Accuitomo 3DX. There was a fair correlation between clinical analysis and the tomographic scorings (rs = 0.238; P = 0.103). It was concluded that pediatric dentists were not able to classify the fissures depth by visual analysis correctly.
