Summary A newly designed root canal filling material, prepared by coating silver cones with guttapercha, was compared with heat‐sealed gutta‐percha and amalgam to evaluate its effectiveness as a root canal sealer using a dye penetration method in vitro. The study indicated that silver‐percha cones are more effective in their sealing ability than retrograde amalgam and heat‐sealed gutta‐percha. The heat‐sealed gutta‐percha was shown to provide an inferior seal.
