Injectable calcium phosphate and styrene–butadiene polymer-based root canal filling material

Background Three-dimensional obturation of the root canal system is mandatory for a successful root canal treatment. Using a filling material with optimal properties may enable the root canal to be sealed well and therefore obtain the desired obturation. Objective To develop a new injectable paste endodontic filling material using calcium phosphate powder and a styrene–butadiene emulsion polymer. Methods The powder phase comprised an equivalent...
