case_images: One month following the traumatic injury, the patient presented with discomfort, infra-occlusion, and swelling in the buccal sulcus over the apex of tooth #21 (Figure 1).
case_images: A periapical radiograph one-month following trauma illustrating a wide-open apex on tooth #11, and evidence of resorption on two-thirds of the distal aspect (arrow). There is evidence of spontaneous apexification (arrow) on tooth #21 with a radiolucent area on the distal aspect of the root close to the apical dome.

case_images: Radiographic examination revealed a wide-open apex on tooth #11 consistent with the patient's age, with evidence of resorption on the distal aspect of the root (Figure 2).

case_images: There was a detectable barrier at a working length of 20 mm, and the entire root was obturated with MTA (Dentsply Sirona, Auckland, New Zealand; Figure 3).

case_images: Excellent bone quality was noted at the marginal aspect of the tooth during extraction (Figure 9), and the site healed uneventfully.
