Indian Journal of Dental Research. 2002 Jan-Mar; 13(1): 31-6http://imsear.searo.who.int/handle/123456789/51779The 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.engBismuth --chemistryColoring Agents --diagnostic useDental BondingDental Leakage --classificationDrug CombinationsEpoxy Resins --chemistryGutta-Percha --chemistryHumansMaterials TestingMethenamine --chemistryMethylene Blue --diagnostic useResin Cements --chemistryRoot Canal Filling Materials --chemistryRoot Canal ObturationRoot Canal PreparationSilver --chemistryStatistics as TopicTitanium --chemistryZinc Oxide-Eugenol Cement --chemistryComparative Study
