RESUMEN
The importance of apical seal has always been stressed in endodontic therapy. Root canal sealers have been used along with gutta percha to enhance the seal. The apical sealing ability of AH26/silverfree, a modified version of AH26, a resin based sealer was compared with tubliseal, a zincoxide eugenol based sealer using methylene blue dye penetration method. AH26/silverfree showed superior sealing ability.

The main objective of endodontic therapy is complete obturation of the root canal system after it has been adequately prepared and sterilised. A wide variety of root canal sealers are available for obturation of the root canal system. A number of different invitro methods have been used to evaluate the sealing ability of endodontic filling materials. By combining one or two tests it may be possible to obtain information about sealing ability of the test material. Therefore, the present invitro study compared the sealing ability of three different root canal sealers, namely Sealapex, AH-26 and ZnOE by two different methods, bacterial leakage and dye penetration. The results showed that AH-26 has the maximum sealing ability followed by Sealapex and ZnOE.
