An ideal root canal sealer should have all the mentioned properties: 1) Fills the space between cone and canal walls - primary mechanical function, 2) Should have antibiotic properties - to eliminate residual bacteria and prevent reinfection, 3) Should be biologically acceptable - biocompatible with periapical tissues, non-toxic, and non-irritating, 4) Additional ideal properties include: dimensional stability, easy mixing and placement, radiopacity, and easy removal if retreatment needed. No current sealer meets all ideal requirements completely, but these remain the goals for sealer development.
