摘要
Abstract
Objective:To observe apical sealing ability on two root canal obturators after post space preparation. Method: Forty extracted human single-rooted human teeth were mechanically prepared using the step-back technique and then assigned to 4 experimental groups randomly of 10 teeth each, filled with lateral condensation technique or vertical condensation technique respectively .Post space preparation was done on 2 groups with different fillings after 7 days. another as negative controls. Apical microleakage was evaluated with ink dye penetration. Result: There were no statistically difference between negative controls (P >0.05).More microleakage were detected after Post space preparation (P <0.01). Conclusion: Post space preparation decreases apical sealing ability ,and less microleakage were created when filled with vertical condensation technique than with lateral condensation technique.关键词
