Abstract

External cervical resorption (ECR) is a pathological state that rarely causes symptoms; however, in some cases, the teeth may have to be extracted. Due to its progressive nature, appropriate diagnosis and early treatment are recommended; however, the indications are not always clear.

A 10-year-old girl with a submerged maxillary right central incisor sought orthodontic treatment. She had no history of trauma or prior orthodontic intervention. Cone beam computed tomography (CBCT) was performed on the discolored teeth, and she was diagnosed with Patel’s 3Dp. However, because of the location of the sprout, it was difficult to achieve moisture control with a rubber dam and subsequent infection. The resorptive tissue present within the root canal was excavated, a temporary root canal filling was placed, and a final root canal filling was performed under a moisture-proof rubber dam to seal the defect. Resorptive tissues were debrided using ultrasonic tips, and root canal filling was performed using the lateral condensation technique.

After root canal filling, non-surgical restorative treatment of the resorption area was performed. Although the gingival morphology was abnormal during prognosis observation, the patient was satisfied.

Orthodontic treatment and an appropriate treatment sequence ensured favorable outcomes in ECR of a submerged maxillary central incisor. Successful ECR treatment relies on prompt management. However, infection control is also important for proper root canal treatment; therefore, it is necessary to choose the treatment sequence by determining the most important factor at the right time.
