2.4. Sealer Application
PAD
Endosequence and Endoseal are available as premixed pastes whereas Sealapex is dispensed as a two-paste system. Sealapex was mixed as per the manufacturer’s instructions by dispensing equal lengths (5 mm) of base and catalyst pastes onto a mixing pad and homogeneously mixing using a cement spatula. A #25 lentulospiral (MANI, Japan) was attached to a slow-speed handpiece (Nakanishi, Japan) and used for sealer placement. The 5 mm tip of the lentulospiral was dipped twice in sealer to obtain an even coating. All lentulospiral sealer applications were performed 2 mm short of the working length to prevent extrusion.
