Objective The purpose of this investigation was to evaluate density value on anterior of the alveolar and basal bones on children. Methods 138 cases cone beam computed tomography images were selected. The densities of these bones were measured in Hounsfield units（Hu） for the incisor, canine of the anterior area of alveolar and basal bones on the children. Results There is no significant difference on the same position of the maxillary bilateral（right and left） incisors of the density value（P>0.05）. To compare with the incisors of the density value on the same position of the mandibule on left and right, there is significant difference on the base bone on cortical bone density of lingual, P=0.012. There is no significant difference on the same position of the maxillary bilateral（right and left） canine of the density value. To compare with the canine of the density value on the same position of the mandibule on left and right, there is significant difference on the alveolar bone and basal bone cancellous density, P=0.046 and 0.002, respectively. Conclusion These might provide determinate data for anterior teeth zone when selecting sites and placement methods for microscrew implants in the dental arch.
