Paste Fillers

Paste Fillers for Coating Root Canals With Endodontic Sealer

Gutta percha alone doesn’t fully seal a canal, since even a well-fitted point leaves microscopic gaps along the canal wall that sealer cement is meant to fill. Paste fillers are spiral-shaped hand instruments used to carry that sealer down the length of the canal and coat the walls evenly before the primary gutta percha point is seated and condensed into its final position.

Because the flutes are spiral-cut, spinning the filler slowly inside the canal draws sealer along the walls rather than pushing it straight to the apex all at once, which helps avoid over-extending material past the root tip. Most clinicians use a slow handpiece or a hand-driven motion rather than high speed to keep the paste under control. 3D Dental carries paste fillers as part of its endodontic instrument lineup for practices doing regular obturation work.
