• Bioactive: Contains calcium hydroxide to stimulate secondary dentin and hard tissue formation.

• Non-Eugenol: Compatible with composite resins and bonding agents; won't cause discoloration.

• Radiopaque: Highly visible on X-rays for easy post-operative verification.

• Long Working Time: Remains usable on the mixing pad for up to 2 hours, even in humid conditions.

• Low Shrinkage: Provides excellent dimensional stability for a reliable seal.

• Easy Handling: Smooth consistency for effortless delivery into the canal.

Kerr Sealapex is the original non-eugenol, polymeric calcium hydroxide root canal sealer. It is designed to provide a fluid-tight seal while actively promoting the formation of hard tissue (cementum) and rapid healing at the apex. Because it is eugenol-free, it does not inhibit the polymerization of resin-based restorative materials.

• Chemical Type: Polymeric Calcium Hydroxide.

• Working Time: Approximately 2 hours on the mixing pad at room temperature ($23^\circ\text{C}$).

• Setting Time: Sets in approximately 45 minutes after placement in the root canal (accelerated by body heat and moisture).

• Film Thickness: $< 50\mu\text{m}$ (meets ISO 6876 standards).

• Solubility: Low solubility once fully set to maintain the integrity of the fill.

The standard kit (Part No. 18432) typically includes:

• 1 x Base Tube (12g)

• 1 x Catalyst/Accelerator Tube (18g or 12g depending on regional SKU)

• 1 x Mixing Pad

• Preparation: Thoroughly clean and dry the instrumented root canal.

• Mixing: Extrude equal lengths of Base and Catalyst onto the mixing pad.

• Spatulation: Mix the two pastes for about 30 seconds until a uniform, streak-free color is achieved.

• Application: Use a Lentulo spiral or a gutta-percha point to carry the sealer into the canal.

• Obturation: Insert the primary gutta-percha cone and proceed with your preferred obturation technique (lateral or warm vertical condensation).

• Manufacturer: Kerr Endodontics (formerly SybronEndo).

• Indications: Permanent obturation of the root canal system in combination with root canal points (Gutta Percha).

• Warranty: Typically covered by the standard manufacturer’s warranty against defects at the time of purchase.

• Storage: Store at room temperature ($15^\circ\text{C}$ to $30^\circ\text{C}$). Keep tubes tightly capped when not in use to prevent moisture contamination.
