Endo Sealer Solvent™: The First Irrigant That Tackles Bioceramic Sealer Retreatment Without Sacrificing Dentin

September 11, 2025

Bioceramic sealers and calcium hydroxide have been excellent for many endodontic applications — excellent sealing, favorable biocompatibility, bioactivity. But when it comes time for retreatment, many clinicians face a dilemma: how to remove the old sealer or medicament effectively without damaging dentin or over-instrumenting the canal.

That’s where Endo Sealer Solvent comes in — the first irrigant purpose-built to dissolve bioceramic sealer and calcium hydroxide while preserving the structural integrity of the tooth. VistaApex has developed a patent-pending formula of acids and surfactants that works selectively, safely, and efficiently.

What makes it different?

  • Selective Dissolution: Unlike strong solvents or aggressive mechanical removal, Endo Sealer Solvent targets bioceramic sealers and calcium hydroxide specifically, leaving dentin unharmed.
  • Versatility: Compatible with all bioceramic sealers + calcium hydroxide pastes. No need to switch products depending on your sealer.
  • Carefully engineered chemistry: The acid + surfactant blend is patent-pending, optimized for efficacy without over-erosion.
  • Procedure efficiency: Designed to streamline retreatments (especially two-visit ones), reducing time in the operatory while improving removal of old material.

Clinical Use: How to Use Endo Sealer Solvent Properly

  1. Assessment & Access: After removing gutta percha or old filling (in retreatment), establish working length.
  2. Irrigate + Soak: Use the solvent with an appropriate irrigation tip (e.g., 30ga), alternating flushing and soaking for about 30 seconds until the canal contents begin to run clear. Around 6-12 mL per canal is typical.
  3. Optional Activation: Ultrasonic activation can help reach irregularities or hard to access areas.
  4. Rinse thoroughly before any strong oxidizers (e.g. sodium hypochlorite), to avoid chemical interactions.
  5. Dry and obturate: Once clean, proceed with usual obturation protocol.

Applications / Ideal Scenarios

  • Retreatment of canals sealed with bioceramic sealers
  • Removal of calcium hydroxide used as interim medicament
  • Cases where dentin preservation is crucial (e.g., thin roots, retreatment in challenging anatomy)
  • Any retreatment where time efficiency and cleanliness are high priorities

Benefits for Practices & Patients

  • Cleaner, more predictable retreatments → fewer failures, less need for aggressive instrumentation
  • Shorter chair-time → better scheduling, more satisfied patients
  • Preservation of tooth structure → better longevity of teeth
  • Distinction in your practice: being equipped for modern bioceramic sealer cases, both new and retreatments

Conclusion

If you’ve wondered whether replacing or removing bioceramic sealers is even feasible without compromising dentin — now you have an answer. Endo Sealer Solvent from VistaApex offers a new, efficient, safe tool for retreatments. The next time you face a bioceramic sealer retreatment or calcium hydroxide removal, you can do so with confidence, precision, and care.
