title: Invasive cervical resorption Class III in a maxillary central incisor: diagnosis and follow-up by means of cone-beam computed tomography.
abstract: BACKGROUND
  Invasive cervical resorption (ICR) is a type of external resorption that begins below the epithelial attachment. The etiology of ICR is mainly caused by trauma or orthodontic treatment. In many cases, cone-beam computed tomography (CBCT) is a very useful tool to achieve proper diagnosis.
  
  
  METHODS
  This case presented with invasive cervical resorption class III (Heithersay) caused by trauma on tooth #9. CBCT was performed allowing observation of the extent of the lesion in the three spatial planes.
  
  
  RESULTS
  Treatment was combined: surgical treatment to expose the resorptive defect and nonsurgical root canal therapy to remove the necrotic pulp and disinfect the root canal system; finally, the resorptive defect was filled up with resin ionomer (Geristore; Den-Mat Corporation, Santa Maria, CA).
  
  
  CONCLUSIONS
  Follow up x-ray films showed healing of the periradicular tissues, and then a control CBCT was performed to assess the reliability of the conventional x-ray film; a small periapical lesion was observed in two of the CBCT sections.
