Early in my career I had a conversation with a doctor who had a lot of clinical experience with endo and he explained to me why the sealer is so important. If you really think about it on a microscopic level, gutta percha, even if it is heated and plasticized, cannot easily flow into all the nooks and crannies of the canal system. Even properly cleaned and shaped canals are not uniform in shape. The job of the sealer is to get into all those little areas that are in the canal system and fill them. The idea is to eliminate voids and bacteria.
The doctor explained to me that he considered the sealer to be *more* important in healing than the gutta percha. He also told me that he looked at the cone as a piston that was used to create hydraulic pressure and drive the sealer into all of those little areas that remain after instrumentation. After that conversation, I began to pay a lot more attention to what type of sealer I used.
When bioactive sealers came on the market I felt that, anecdotally, I was getting better results. Post-op pain became much less common and healing seemed better. Now I'll be the first one to say that is completely my experience and NOT a scientific study... but I do feel these new bioactive sealers give me a better result.
That's why I was really excited to see this new sealer from Vista-Apex. The company has done a great job in the last 2-3 years with their Re-Gen products so when I saw they were bringing an endo sealer to market I was excited. I have not used the material yet. It just arrived in my office yesterday, but you can bet that I will be trying it on my next case. Give me some time to get a few cases done and I will report back to you here.
Following is what the company has to say about this new product:
RE-GEN™ Bioactive Endo Sealer is a hydraulic, ready-to-use injectable bioactive paste that utilizes moisture naturally present in dentinal tubules to initiate a setting reaction. Endodontic sealers are used in the obturation of root canal systems to achieve a fluidtight seal throughout the canal including the apical foramen, canal irregularities, and minor discrepancies between the dentinal wall of the root canal and the core filling material.
• Employs Bioglass to promote bio-regenerative healing while attracting and exchanging ions that promote remineralization of hydroxyapatite and reduces inflammation
• Ready to use: Injectable, single-component, bioactive paste with smooth flow handling
• Biocompatible and Osteogenic: Bioactive root repair material that is effective on non-vital cases
• Anti-bacterial: Creates a high alkaline environment to prevent bacteria formation
• Dimensionally stable: Low solubility with high wash out resistance
• A faster set: Fast and efficient set time of under 1 hour
• Highly Radiopaque
• Cost Effective + Paired with material savings MST Visco-Tip™
