Orthodontic anchorage has been cause of concern to orthodontists since the specialty beginnings. It is no exaggeration to say that its control is a determining factor regarding the success or failure of orthodontically treated cases. With the advent and popularization of orthodontic mini-implants, anchorage problems were minimized and, often, eliminated. The popularization of mini-implants occurred due to favorable characteristics such as: effectiveness, facility for insertion and removal, reduced size, low cost, etc. However, despite many positive aspects, complications may occur when using it. The possibility of root injury is specially mentioned. However, what would be the real repercussions of these lesions on the healthiness of the injured teeth? In search of an answer to this question, Brazilian researchers1 developed a systematic review aiming at assessing root repair after contact of the miniimplant with the root of adjacent teeth. The results revealed that the quality of root repair depends on the damage caused during mini-implant insertion. According to the authors, when the root injury is limited to the dentin and cement area, complete periodontal repair can occur. It is worth emphasizing that, although the results are favorable to repair, we must be careful to avoid injuries to the periodontium, considering the lack of long term studies.
