Kerr Sealapex Calcium Hydroxide Root Canal Sealer
A radiopaque, non-eugenol calcium hydroxide root canal sealer in a two-paste system, built for smooth mixing, controlled placement, and dependable obturation with gutta-percha.
A root canal sealer must adapt between prepared dentin and the obturation core while remaining easy to mix, place, and control. Kerr Sealapex is a polymeric, calcium hydroxide–based sealer developed for permanent endodontic obturation with gutta-percha. It is supplied as separate base and catalyst pastes that mix to a smooth, workable consistency for controlled placement along the prepared canal walls.
The calcium hydroxide chemistry is really what sets it apart. Instead of the eugenol base found in many traditional sealers, Sealapex uses a non-eugenol polymer system built around calcium oxide in the base paste. Once mixed, it forms a clinically manageable sealer layer around the obturation material, formulated for tissue compatibility when used according to the manufacturer's protocol.
Sealapex is designed to adapt between the prepared canal walls and the gutta-percha, filling small irregularities the solid core material can't occupy on its own. That supports a more continuous obturation interface — though, as with any sealer, this isn't a guarantee of complete leakage prevention. Controlled placement still matters, and material should never be forced beyond the apical foramen.
Because it's radiopaque, both the sealer and the completed obturation show up clearly on postoperative radiographs, which makes it easier to assess the extent, density, and general distribution of the fill after treatment. And since it's a paste-paste system, you're mixing only what you need for the procedure at hand, without unnecessary waste.
The kit contains a 12 g base tube, an 18 g catalyst tube, and a mixing pad. Between the straightforward mixing system, the calcium hydroxide–based chemistry, and its compatibility with gutta-percha, Sealapex remains a practical choice for routine permanent root canal obturation.
