Bioceramic Sealers

About bioceramic sealers

Bioceramic sealers are hydrophilic root canal sealers based on calcium silicate and phosphate, which set using the moisture in the dentinal tubules. They are premixed, and made of zirconium oxide, calcium silicates, monobasic calcium phosphate, calcium hydroxide and a thickening agent. They set using the moisture already present in the dentinal tubules, because they are hydrophilic and insoluble. They are described as dimensionally stable, and they bond to dentine by tubular diffusion, which interlocks mechanically.

Water-based, and set by the moisture in the tooth. A meta-analysis of leakage tests found no significant difference in sealing ability between bioceramic and epoxy resin sealers.
