Ideal Properties of an Endodontic Sealer

1. Viscosity which enables flow to apex, without extrusion, into lateral canals and dentinal tubules.
2. Mechanical and/or chemical adhesion to root dentine.
3. Mechanical and/or chemical adhesion to gutta-percha or other core material.
4. Particle size distribution to allow flow into lateral canals and tubules but not through apex.
5. Solvent available for easy removal.
6. Insoluble in tissue fluids.
7. Non-toxic.
8. Promotes hard tissue bridge formation.
9. No discolouration of tooth.
10. As radiopaque as the core material.
11. Bacteriostatic or bacteriocidal.
12. Dimensionally stable when set.
13. Minimum setting contraction or expansion.
14. Clinically satisfactory working and setting times.
15. Impervious to bacteria and bacterial toxins.
