title: Leakage of teeth root-filled with GuttaFlow and a single GP cone compared to lateral condensation and warm vertical condensation.
abstract: BACKGROUND
  Root canal obturation can be time consuming and complicated. GuttaFlow is suggested for use with a simple, single cone obturating technique.
  
  
  OBJECTIVE
  The aim of this study was to evaluate whether GuttaFlow and a single GP cone would produce an effective seal.
  
  
  METHODS
  Three experimental groups were used. Group one was obturated with GP using lateral condensation, group two with GP using vertical condensation and group three using GuttaFlow and a single GP cone. Bacterial micro-leakage was tested using the two-chamber method, followed by dye penetration testing. Data was subjected to statistical analysis using the Chi Square test.
  
  
  RESULTS
  There was no significant difference between GP using lateral condensation and GuttaFlow using a single cone for bacteria (p=0.8989) or dye (p=0.7489). GP using lateral condensation performed better than GP using vertical condensation for bacteria (p=0.0003) and dye (p=0.0006). GuttaFlow using a single cone also performed better than GP using vertical condensation for bacteria (p=0.0003) and dye (p=0.0004).
  
  
  CONCLUSIONS
  The micro-leakage of GuttaFlow using a single cone technique is similar to that of GP using lateral condensation and less than that of GP using vertical condensation as used in this study.
