title: Apical limit of root canal filling and its relationship with success on endodontic treatment of a mandibular molar: 11-year follow-up.
abstract: OBJECTIVE
  This article discusses the relationship between apical limit of root canal filling and success on endodontic treatment of a mandibular molar.
  
  
  METHODS
  A mandibular right first molar with vital pulp was endodontically treated, and 3 years later periapical lesions on mesial and distal roots were detected. The canals were retreated and obturated to the same levels as in the previous treatment.
  
  
  RESULTS
  An 8-year radiographic follow-up showed repair of the periapical lesions on both roots.
  
  
  CONCLUSIONS
  Results suggest that the apical limit of obturation seems to have no influence in the repair of periapical tissues in mandibular molars.
