title: Microleakage of various root filling systems by glucose filtration analysis.
abstract: OBJECTIVE
  The aim of this study was to evaluate the microleakage of Resilon + Epiphany, EndoRez, Activ GP, and conventional AH Plus + gutta-percha technique using the glucose filtration model.
  
  
  METHODS
  One hundred twenty maxillary incisors were divided into 5 experimental and 2 control groups. After root canal shaping, the experimental groups were filled with AH Plus + gutta-percha (lateral compaction), Resilon + Epiphany (lateral compaction), AH Plus + Protaper's proprietory cone, EndoRez + sealer, or Activ GP + sealer). The specimens were mounted on a glucose model and samples were taken for 3 weeks for leakage measurement.
  
  
  RESULTS
  No statistically significant difference was observed between the leakage of all groups at the 3 testing periods (P > .05).
  
  
  CONCLUSIONS
  The filling materials with the monoblock concept do not seem to be superior to the conventional AH Plus + gutta-percha system regarding microleakage.
