title: Revitalization procedures in two traumatized incisors with different biological outcomes.
abstract: BACKGROUND
  The revitalization of a previously necrotic pulp space has been shown to be possible and even considered predictable. However, exact criteria for success are still lacking, and, in fact, some cases do not respond as predicted.
  
  
  METHODS
  In this case, the same operator treated 2 teeth similarly according to the principles laid out by Banch and Trope. The tooth that according to our expectations was more likely to be revitalized successfully failed to do so, whereas the second tooth that, in our estimation, was less likely to succeed was successful. In the tooth that failed to revitalize, auto-apexification occurred.
  
  
  CONCLUSIONS
  Complete understanding for the criteria for predictable revitalization and apexification is still lacking.
