case_images: Periapical radiographs and CBCT sections of maxillary central incisor. (A) Preoperative periapical radiograph showing extensive periapical radiolucency with open apex. (B) Preoperative CBCT scan (Sagittal view) shows 2mm open apex measurement. (C) Axial view showed the extent of bone defect.

case_images: The external walls of the root's apical third were irregular, which was a clear sign of inflammatory apical root resorption (Figure 1A). The axial view showed the radiolucency with 8.9*9.5 mm, perforating the labial cortical plate (Figure 1B and C).

case_images: Using an electronic apex locator (Root ZX, J Morita, Tokyo, Japan) and a periapical radiograph with H-file size 60, the working length was ascertained (Figure 2).

case_images: A thin homogenous layer of about 2 mm of hydraulic silicate cement MTA (MTA- Angelus, Brazil) was applied on top of the collagen matrix beneath the cemento-enamel junction (Figure 3).
case_images: Periapical radiographs and CBCT sections taken at one-year recall. (A) postoperative radiograph demonstrating slight decrease in the size of the periapical radiolucency. (B) Root thickness showed slight changed compared with the preoperative CBCT scan. (C) Axial view showed reduction in size lesion.
