Abstract
STATEMENT OF THE PROBLEM: , a weak chelating agent, has been introduced to the market. However, its chelating capacity in the final irrigation protocol with different activation systems has not yet been deeply analyzed. PURPOSE: study was to evaluate the effectiveness of passive ultrasonic irrigation (PUI) and XP-endo Finisher (XP) on smear layer removal in combination with two chelating agents, ethylenediaminetetraacetic acid (EDTA) and etidronic acid (HEDP). MATERIALS AND METHOD: > 0.05 as significant. RESULTS: < 0.003). There were no statistically significant differences among the other groups. CONCLUSION: study, no activation system was able to completely remove the smear layer from the root canal walls. However, the combination of NaOCl with ultrasonically activated EDTA obtained better results than the other treatments.
