Abstract

Internal root resorption may occur in cases of chronic inflammation of the dental pulp. The etiologies of internal root resorption are caries, previous dental treatment, or trauma from orthodontic treatment. Most internal root resorption occurs in the anterior teeth.

This article presents a case of a 21-year-old Thai female patient who was undergoing orthodontic treatment. The orthodontist found internal root resorption on an X-ray during treatment. An emergency root canal was performed and the patient was referred for further treatment.

          The patient underwent examination and found that the oral mucosa was normal with no sinus opening. Tooth 22 had a good restoration and no leakage. Palpation and percussion test were normal. Periapical film showed 4 x 6 mm2 internal root resorption and a 1 x 1 mm2 periapical lesion. Cone beam computed tomography (CBCT) showed the internal root resorption toward the labial side with 0.58 mm of root dentine remaining. The prognosis of this tooth was good because the root had not yet been perforated. Treatment plan was root canal treatment, repair internal root resorption with MTA, restore with a post and a core. After the orthodontic treatment was completed, this tooth will be restored with crown, in that order to receive continuous orthodontic treatment. After 3 months follow up, the results were found to be satisfactory. The patient had no any symptom and persist periapical lesion.
