title: Long-term sealing ability of GuttaFlow versus Ah Plus using different obturation techniques.
abstract: OBJECTIVE
  To compare the long-term sealing ability of GuttaFlow® using different obturation techniques.
  
  
  METHODS
  Three hundred teeth, prepared with a crown-down technique, were divided into thirty experimental groups (n=10) to evaluate the apical and coronal leakage, at 3, 30 and 120 days, of lateral compaction gutta-percha+AH Plus TM, lateral compaction gutta-percha+GuttaFlow®, single cone+AH Plus TM, single cone+GuttaFlow®, and GuttaFlow® only.
  
  
  RESULTS
  Both coronal and apical leakage, at the three times of measurement, no significant differences were found among GuttaFlow®+lateral compaction gutta-percha and GuttaFlow®+single cone groups, whereas the only GuttaFlow® reached the highest leakage values at 30 and 120 days. AH Plus TM, using both techniques, showed high levels of leakage after 120 days to the coronal leakage and after 30 days to the apical leakage when compared silicon based sealer.
  
  
  CONCLUSIONS
  GuttaFlow®, using with lateral compaction and single cone techniques, shows a greater apical and coronal sealing ability than AH Plus TM over time. GuttaFlow® when used as only creates a poorer sealing when used with lateral compaction gutta-percha or single cone techniques.
