Chemical Stability and Bond Strength of Endodontic Sealers Exposed to Acidic, Alkaline and Protein‐Rich Environments: An In Vitro Investigation

Australian Endodontic Journal, Volume 52, Issue 1, Page 139-147, April 2026.
ABSTRACT The sealing performance of endodontic sealers may be influenced by environmental factors such as pH and blood‐derived proteins. This in vitro study evaluated the effects of pH variation and protein contamination on calcium ion (Ca2+) release and push‐out bond strength (BS) of a calcium silicate‐based sealer (Bio‐C Sealer) and an epoxy resin ...
