Learn practical clinical tips for using EndoREZ root canal sealer. This guide covers preparation, application, and common mistakes to ensure successful endodontic obturation.
Quick Answer
EndoREZ is a hydrophilic, self-priming resin sealer that bonds to moist dentin. For best results, use a controlled delivery system like a NaviTip tip and a 5 ml Delivery Syringe to place the sealer precisely without voids.
Understanding EndoREZ’s Unique Properties
EndoREZ is the world’s first hydrophilic and self-priming resin sealer. Unlike traditional hydrophobic sealers, it actively wets the canal walls even in the presence of residual moisture, which improves adaptation and reduces the risk of gaps. This property makes it particularly useful in cases where complete drying is challenging.
Choosing the Right Delivery System
Precise placement of EndoREZ is critical for void-free obturation. The NaviTip Tips are designed to deliver endodontic sealers and irrigants with accuracy. When paired with the 5 ml Delivery Syringe, you get ergonomic control and leverage, allowing you to express the sealer slowly and steadily from the apex to the coronal aspect.
Step-by-Step Clinical Workflow
- Prepare the Canal: Complete cleaning and shaping to the desired master apical file size. Irrigate with sodium hypochlorite and EDTA, then dry with paper points. Leave the canal slightly moist—EndoREZ requires moisture to initiate its hydrophilic action. Checkpoint: Avoid overdrying. A visibly damp canal is acceptable.
- Mix and Load the Sealer: Dispense EndoREZ base and catalyst onto a mixing pad and mix according to the manufacturer’s instructions. Draw the mixed sealer into a 5 ml Delivery Syringe fitted with a NaviTip tip. Ensure no air bubbles are trapped in the syringe. Common mistake: Skipping the mixing step or using a dry tip can introduce voids.
- Deliver the Sealer into the Canal: Insert the NaviTip tip to within 1–2 mm of the working length. Slowly express sealer while withdrawing the tip. You should see sealer flowing back toward the orifice. Stop when the canal is filled without overflow. Checkpoint: If sealer does not flow back, the tip may be too deep or the sealer too viscous.
- Place the Master Cone: Gently insert a gutta-percha master cone coated with a thin layer of sealer. Use a pumping motion to seat it fully. The sealer will self-prime and bond as the cone is placed. Common mistake: Forcing the cone without coating can cause sealer to be pushed out of the apex.
- Complete Obturation and Cleanup: Use a heated plugger to sear off the excess cone and vertically compact the remaining gutta-percha. Wipe the access cavity with a cotton pellet to remove any residual sealer before it sets. Checkpoint: Clean up excess sealer immediately; once cured, it is difficult to remove.
Product Facts
- EndoREZ™-Root Canal Sealer: EndoREZ root canal sealer is the world’s first hydrophilic and self-priming resin sealer. It bonds to moist dentin, reducing the need for aggressive drying and improving seal quality.
- NaviTip™ Tips: NaviTip Tips easily deliver endodontic sealers, irrigants, and more. The tip design allows precise placement of EndoREZ directly into the canal, minimizing voids and excess sealer.
- 5 ml Delivery Syringe: The 5 ml Delivery Syringe has flanges positioned for optimum control and leverage. Better control during sealer injection leads to consistent flow and reduces hand fatigue during multiple procedures.
