Root resorption is one of the common and important complications during orthodontic treatment, which is mainly manifested as the gradual destruction of the root structure.
Its mechanism of occurrence is believed to be an inflammatory response involving the pathological process of ischemic necrosis, so it is called orthodontically induced inflammatory root resorption (OIIRR).
This complication not only affects the structural integrity of the teeth, but also may threaten the long-term stability and function of the teeth.
Recently, a clinical case report on a patient in his 20s has attracted attention. After orthodontic treatment, the patient experienced internal root resorption of two maxillary central incisors.
To address this situation, the researchers used mineral trioxide aggregate (MTA) as a treatment material and applied it directly to the root resorption lesions to promote the remineralization process of the roots.
Follow-up data showed that after 3 years of observation, no radiolucency related to root resorption lesions was found in clinical examinations and X-ray images, indicating that the root structure tended to be stable and there was no further deterioration.
At the same time, the patient did not experience any pathological symptoms such as pain or loose teeth during this period, showing a good treatment effect.
This case not only provides a new idea for the treatment of orthodontically induced root resorption, but also shows the potential of MTA in promoting root tissue repair.
In the future, with the continuous development of relevant technologies and materials, the management of orthodontic treatment complications will be more effective, and the patient’s treatment experience and efficacy will be significantly improved.
