title: Periapical lesions accidentally filled with calcium hydroxide.
abstract: OBJECTIVE
  To evaluate the effect of accidental and voluminous calcium hydroxide overextensions into periradicular lesions and tissues on the prognosis of periapical healing.
  
  
  CONCLUSIONS
  Eleven cases with periapical lesions and voluminous calcium hydroxide overextension are presented. Despite literature reports on the deleterious effects of calcium hydroxide extension in the periapical area, none of the endodontic treatments failed and surgical intervention was not indicated.
  
  
  CONCLUSIONS
  Extensive extrusion of calcium hydroxide into the periapical tissues does not appear to comprise periapical healing. Despite this finding, the deliberate extrusion of dental materials into the apical tissues is not advocated.
