Kerr Pulp Canal Sealer EWT extended working time endodontic sealer, kit

KERR Pulp Canal Sealer™ EWT – Extended working time endodontic sealer (kit)

Pulp Canal Sealer™ EWT is the extended working time version of Kerr's iconic endodontic sealer. Based on zinc oxide and eugenol, this radiopaque sealer is specifically designed to offer consistent flow and an exceptional working time (6-8 hours). It is the product of choice for thermoplastic obturation techniques that require material stability under thermal stress.

Advanced performance for specialist endodontics

• Extended Working Time (EWT): It remains workable for 6-8 hours after mixing on the slab. This allows the clinician to work with complete calm, ideal for complex multi-canal treatments or cases involving numerous condensation steps.

• Heat stability: Unlike other sealers, the EWT formula is optimised not to accelerate setting on contact with the hot instruments used in vertical gutta-percha condensation techniques.

• Superior hermetic seal: Its balanced viscosity allows it to penetrate lateral and accessory canals, ensuring three-dimensional sealing of the root canal system and preventing apical leakage.

• Distinctive radiopacity: Ensures sharp, precise contrast in post-operative radiographs, essential for validating the quality of the endodontic obturation.

• Excellent lubrication: Helps gutta-percha cones slide, reducing friction and improving adaptation of the material to the dentine walls.

Clinical indications

• Permanent root canal obturation with gutta-percha cones.

• Warm vertical and lateral condensation techniques.

• Clinical cases with particularly long or complex canal anatomy.
