Experimental apical sealing with a new canal obturation system.
Twenty-seven root canals were obturated by the Thermafil system after conventional preparation. The lateral condensation technique was used as a control in 11 other canals. All specimens were immersed passively in India ink for 3 days at 37 degrees C. After rendering all roots transparent, no statistically significant differences (p < 0.4) were seen in apical leakage as determined stereomicroscopically. Like-wise, no relationship was noted between leakage and the last apical file size used to prepare and clean the canals.
