Purpose:
To evaluate the apical sealing ability of two root canal sealers.
Methods:
Fifty recently extracted human anterior teeth with a single canal (α<5; Schneider's method) were divided randomly into two experimental groups(twenty teeth in each group), as well as positive and negative control group (five teeth in each group). The root canals were instrumented using Protaper file to F2, and were obturated with iRoot SP with continuous wave obturation technique (group A), AH plus with continuous wave obturation technique (group B). The apical microleakage was evaluated by dye penetration method. Linear dye penetration was measured and analyzed by SPSS13.0 software package.
Results:
Mean depth of leakage for groups with the smear layer intact was (1.46±0.21) mm for group A, (1.52±0.22) mm for group B, (10.75±1.28) mm for positive control group, and 0 mm for negative control group. The value of the experimental group B was greater than group A, but there was no significant difference between the 2 groups.
Conclusion:
iRoot SP displays similar in vitro apical sealing ability to AH plus.
