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.
Study design
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.
Conclusion
The filling materials with the monoblock concept do not seem to be superior to the conventional AH Plus gutta-percha system regarding microleakage.
