Consepsis V-2% Chlorhexidine: Irrigation Protocol

Quick Answer

Use Consepsis V-2% Chlorhexidine Viscous Solution as a final irrigant after sodium hypochlorite to maximize antibacterial action while minimizing apical extrusion.

Step-by-Step Irrigation Protocol

1. Prepare the Canal: Complete mechanical shaping and irrigation with sodium hypochlorite. Rinse the canal with sterile saline or distilled water to remove residual hypochlorite. Common mistake: leaving hypochlorite in the canal can cause precipitation when chlorhexidine is introduced.
2. Load Consepsis V-2% into a Syringe: Use a 27-gauge or smaller side-vented irrigation needle. Attach to a Luer-lock syringe and draw up the Consepsis V solution. Prime the needle to remove air. Checkpoint: ensure the needle fits loosely in the canal to allow backflow and prevent binding.
3. Irrigate the Canal: Place the needle 1–2 mm short of the working length. Slowly express the viscous solution while moving the needle up and down. Fill the canal completely and let it dwell for 60–90 seconds. Common mistake: expressing too quickly can cause apical extrusion. Use gentle, steady pressure.
4. Agitate the Solution: Use a small ultrasonic file or manual agitation with a gutta-percha cone to disrupt the biofilm and distribute the chlorhexidine into lateral canals. Checkpoint: agitation time should not exceed 30 seconds to avoid excessive heat generation.
5. Rinse and Dry: Irrigate with sterile saline or water to remove chlorhexidine residue. Dry the canal with paper points before obturation. Common mistake: leaving chlorhexidine residue can interfere with sealer bond strength.

Product Used in This Protocol

• Consepsis™ V-2% Chlorhexidine Antibacterial Viscous Solution: The viscosity of Consepsis V solution makes it the perfect disinfectant when you want to have more control. The thick consistency keeps the solution in the canal longer and reduces the chance of inadvertent extrusion, especially in wide or apically patent canals.
