Management of Internal Root Resorption on Permanent Teeth
Figure 1
Diagnosis of an apical internal root resorption in a 16-year old patient at the end of orthodontic treatment (tooth 12). (a) Extraoral photograph: The clinical data of the examination are no pain, no crown discoloration, healthy periodontal probing, and thermic and electric pulp; vitality tests are positive (possibly false positive). (b) Panoramic radiograph: note the apical resorption of the right upper lateral incisor. (c) Periapical radiograph confirms the invasive internal resorption in the apical third: the canal disappears with perforation of radicular walls. However, the lamina dura is present. (d), (e), and (f) Sagittal, axial, and coronal CBCT cross-sections. The most likely etiological hypothesis is an inflammatory reaction of the pulp due to traumatic orthodontic procedures. Because of the absence of symptoms, the decision was the abstention with periodical clinic and radiographic controls.
