Root resorption is one of the leading complications that follows orthodontic treatment. It’s an inflammatory process involving ischemic necrosis. Therefore, it is called orthodontically induced inflammatory root resorption (OIIRR). The purpose of this report is to present a case study of a patient in her 20s who experienced internal root resorption on two maxillary central incisors as a result of orthodontic treatment. Mineral trioxide aggregates (MTAs) have been applied to the root resorption lesion to promote remineralization. Clinical and radiographic examination revealed that no radiolucency related to the resorptive lesion was found without any pathological symptoms after a 3-year follow-up.
