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.
根尖封闭在根管治疗中一直备受重视。根管封闭剂一直与牙胶尖联合使用以增强封闭效果。采用亚甲蓝染料渗透法，将AH26/无银（AH26的改良版，一种树脂基封闭剂）的根尖封闭能力与Tubliseal（一种氧化锌丁香酚基封闭剂）进行了比较。AH26/无银表现出了卓越的封闭能力。
