case_images: Radiographs taken before orthodontic treatment did not reveal any radiolucency in this tooth (Figure 1A), but in the recent panoramic radiograph, a resorptive lesion was visibly observed (Figure 1B). The intraoral examination did not reveal any discoloration, pain, or swelling (Figure 1C). The probing depth was within a normal limit (Figure 1D). The periapical radiograph revealed an irregular radiolucency in the cervical and middle third of the root canal area (Figure 1E). A CBCT was recommended to better define and visualize the lesion (Figure 1F,G).

case_images: At the first visit, local anesthesia (xylopen2%, Exsir, Iran) was administered and a conservative access cavity was prepared (Figure 2A). A master apical cone (MAC) with a size of 35 (6%) was then inserted into the working length of the canal and confirmed by radiography (Figure 2C). The MAC was placed in the canal using ENDO Seal MTA sealer (Marruci EndoSeal MTA, USA) and was cut off with a heat carrier at the 3 mm from the apex (Figure 2D,E). Following root canal therapy, the remaining portion of the canal was filled with cold ceramic (Monsefteb, Yazd, Iran) (Figure 2F).
case_images: (A) Tooth was restored with composite resin adhesive. (B) 3-month follow-up, (C) 6-month follow-up, (D) 20-month follow-up.

case_images: The affected tooth was restored using a composite resin adhesive (Figure 3A). Follow-Up: During the 3-, 6-, and 20-month follow-up visits (Figure 3B-D), the patient reported no complications.
