Abstract

Purpose: To evaluate the radiopacity produced by seven commercially available (AH Plus, Epiphany, Sealapex, Acroseal, Sealer 26, Endomethasone and Endofill) and one experimental (MBP) root canal sealers. Methods: Sealer radiopacity testing was performed according to ANSI/ADA Specification No. 57. Specimens were radiographed with an aluminum stepwedge, and the resulting images were digitalized. Radiographic densities expressed in Aluminum mm (mm Al) were compared using an ANOVA and Tukey’s test (α=0.05). Results: AH Plus (10 mm Al) and Epiphany (9.0 mm Al) were the most radiopaque root canal sealers, followed by Sealapex (8 mm Al), Endofill (7 mm Al), Endomethasone (7 mm Al), MBP (7 mm Al) and Sealer 26 (6 mm Al). Acroseal (5 mm Al) showed the smallest radiopacity among the tested sealers (P<0.05). Conclusion: The radiopacities of the tested sealers were above the minimum level recommended by ANSI/ADA Specification No. 57.
