case_images: Preoperative radiographs. Short root, thin hard tissue, and enlarged pulp cavity was evident in teeth 31, 41, and 42. Pulp cavity of 41 was filled with radiopaque material. (a) Tooth 42 merely erupted, and periapical radiolucency was noticed. (b) Tooth 31 fully erupted, and periapical radiolucency was seen.

case_images: Radiopaque material was observed in the pulp cavity of 41 (Figure 1).
case_images: Immediate postoperative panoramic radiograph. Tooth 31 was treated with RET. Tooth 41 had been treated with apexification. Permanent mandibular incisors and canines exhibited poor formation of dental hard tissue.

case_images: In order to examine the position of the blood clot and iRoot BP plug, while in concern that other permanent teeth might also be affected by dentinogenesis imperfecta, a panoramic radiograph was taken (Figure 2).
case_images: Recall radiographs of the case. (a) One-month postoperative radiograph showed alleviation of periapical radiolucency. (b) Three-month postoperative radiograph demonstrated healing of periapical lesion. Maturation of root was not evident. (c) Twelve-month postoperative recall radiograph clearly showed elongation of root and thickening of dentinal canal walls, especially when compared with tooth 41, which was treated with apexification. Dentinal bridge and closure of root apex were also obvious.

case_images: X-ray examination revealed significant decrease of periapical radiolucency (Figure 3(a)). Radiographic examination was performed at 3-month and 12-month postoperative recall, which revealed complete healing of periapical lesion, elongation of the root, closure of the root apex, and obvious dentinal bridge beneath iRoot BP plug (Figures 3(b) and 3(c)).
