case_images: A screening panoramic radiograph (Planmeca Promax 6114 Helsinki, Finland) (Figure 1) was captured to evaluate the dentition and to determine if further diagnostic images are necessary.
case_images: Progress panoramic radiograph eleven months into orthodontic treatment, # A still retained.

case_images: After repeated failure by the patient to exfoliate tooth #A, a progress panoramic radiograph (Figure 2) was captured.
case_images: Progress panoramic radiograph, twelve months after extraction of #A.

case_images: After an additional twelve months of failure to naturally erupt, a second progress panoramic radiograph (Figure 3) was captured to determine the etiology.
case_images: Initial CBCT: (a) coronal section, advanced ECR at apex, (b) axial section arrows indicating lateral extensions, and (c) sagittal section showing lateral extensions.

case_images: At twenty-seven months of treatment, a CBCT scan (Figure 4) (J Morita 3D Accuitomo system at 90.0 kVp, 8.0 mA, 17.5 seconds, resolution 0.08 mm, and field of view 40.2 mm x 40.2 mm x 24.8 mm) was captured for ideal surgical orientation and identification of anatomical structures.
case_images: Enlarged follow-up periapical radiograph tooth #4, 6 months postsurgical exposure.

case_images: At six months postsurgery, a periapical radiograph (Figure 5) (Progeny 60kv, 7 mA, 0.125 s) revealed evidence of ECR progression.
case_images: Follow-up CBCT eight months after surgical exposure. Tooth #4 eruption near to occlusal plane: (a) coronal, (b) axial, and (c) sagittal. Significant progression of resorption. (d) Initial intraoral images and (e) final intraoral image.

case_images: At eight months postsurgery, a follow-up CBCT (same settings as previous CBCT) (Figure 6) and endodontic consultation were repeated. Progression of ECR is evident in the progress CBCT (Figure 6).
