Abstract: One of an important problem during orthodontic treatment is root resorption. Mainly, the root resorption is evaluated by using two-dimensional images. However, the incorrect way for taking the x-ray and magnification is main problem that affect the way for diagnosis of root resorption. The purpose of this study will three-dimensional evaluation of external root resorption during orthodontic treatment. The cone bean computed tomography (Cbct) was used to evaluate the rate of root resorption in maxillary teeth before and after orthodontic treatment. The standardization criteria were used for both treatment, material and Cbct. The results showed significant change in root dimension in three dimensions, length, apical, middle and cervical diameter. The 2nd premolars showed less significantly than other teeth. The anterior teeth were more resorption than posterior one. The overall the results showed all the type of resorption were happened within the normal resorption rate
