An evaluation of coronal microleakage in endodontically treated teeth. Part II. Sealer types

This study compared coronal microleakage in the root canals of teeth obturated with gutta-percha and either Sealapex, AH26, or Roth's sealer. Following obturation the coronal access openings were exposed to artificial saliva for 1 wk and then placed into dye to demonstrate leakage. The specimens were decalcified and cleared and linear measurements were made from the cementoenamel junction to the point of maximum dye penetration. Statistical analysis of the data showed that the AH26 group demonstrated significantly more coronal microleakage than the other groups (p
