ABSTRACT

The aim of this study was to examine and compare the apical sealing ability of AH26, AH Plus and AH Plus Jet using the fluid filtration model. In this experimental study, 70 single-rooted teeth were dissected from the cement-enamel junction. Canals were prepared with ProTaper rotary system and hand K-files and irrigated with 5.25% NaOCl and 17% EDTA. Ten teeth were assigned to the control group and divided into 5 positive and 5 negative controls. Remaining specimens were divided into 3 groups of 20 samples each and filled with gutta percha by lateral condensation technique. Each sample group was filled with either AH26, AH Plus or AH Plus Jet. Microleakage was assessed on the 2[nd] and 30[th] day by the amount of air bubble movement within the capillary glass tube connected to the root. One-way ANOVA test was used for analysis. AH Plus Jet had the least microleakage value and AH Plus presented the highest rate; however, the differences were not statistically significant. Under the conditions of this study, all three studied sealers provided satisfactory seal within the two time intervals. AH Plus Jet demonstrated slightly lower microleakage values; therefore, its application can be recommended in endodontic therapy
