title: Arrest and Calcification Repair of internal root resorption with a novel treatment approach: Report of two cases.
abstract: OBJECTIVE
  We report a novel treatment option for teeth with internal root resorption (IRR) in which the lesion had perforated to the PDL and was located in the coronal aspect of the root. Arrest and calcification of IRR can be achieved by local application of calcium hydroxide without further intracanal instrumentation.
  
  
  METHODS
  Two cases of severe IRR without periapical inflammation were treated with a novel technique: The vital pulp including the granuloma was left in place and subjected to long-term disinfection with application of calcium hydroxide in the coronal aspect of the IRR. In both cases, the radiolucent areas were reduced and showed progressive calcification. Solid barriers were found in the coronal layers of the IRRs, and mineral trioxide aggregate (MTA) was placed as definitive fillings. No apical periodontitis was seen during the follow-up period of 6 years. The root canals appeared to gradually be narrowed. The results were similar to those obtained after successful cervical pulpotomy. Thus, the biological outcome was improved in comparison with pulp extirpation and conventional root canal treatment.
  A treatment option for internal root resorption without periapical inflammation.
