 note = {We decided extraction of tooth because of both a distance of apical root and major arch length discrepancy. A male of 11 years old showed Angle Class I malocclusion of upper anterior crowding and missing lower lateral incisors. Upper lateral incisors extracted to reduce the arch length discrepancy and to make in our treatment plan upper canines move into the lateral incisors position. As a result, we were able to do shortening of treatment periods and to get excellent good alignment without root resorption. It was useful for diagnosis of position relation of apical root to use panoramic tomography and dental micro X-ray tomography (3DX)., application/pdf},
