Clinical Applications of Calcium Silicate Based Sealers


Epoxy resin-based sealers have been commonly used for decades and considered to be the gold standard sealer. However, these kinds of sealers still have limitations such as cytotoxicity, poor wettability to dentin, and host inflammatory response. In 2007, the first bioceramic endodontic sealer was introduced, and this new class of sealer is called calcium silicate-based sealer. Since then, various sealers meet ISO recommendations have been introduced, and many researches showed excellent biocompatibility, antibacterial effects, hydrophilicity and sealing ability of calcium silicate-based sealer. These kinds of sealers establish a biological point of view on the root canal obturation. The bacteria tight seal against re-infection is no longer the only goal of root canal obturation. Bioactive property of calcium silicate-based sealers promotes better apical healing and hard tissue formation and this biological concept will make new standard for the root canal sealers. Now, several premixed ready-to-use injectable calcium silicate-based sealers are on the market, and I’d like to introduce the clinical applications of these sealers in various situation. Thanks to superior wettability and ability to set in moist or blood contaminated environment, you can use these kinds of sealer for the repair of perforated root canal as well as sealing wide, irregular root canals. I’ll share my cases with calcium silicate-based sealers in this lecture.
