Unlike conventional base/catalyst sealers, BC Sealer™ utilizes the moisture natually present in the dentinal tubules to initiate its setting reaction. This highly radiopaque and Hydrophilic sealer forms hydroxyapatite upon setting and chemically bonds to both dentin and to our bioceramic points (EndoSequence® BC Points™). BC Sealer is anti-bacterial during setting due to its highly alakaline pH and unlike traditional sealers, BC Sealer exhibits absolutely zero shrinkage!
