Abstract :Purpose: The aim of present study was to evaluate the color stability of calcium-silicate based cements insert ignore into journalissuearticles values(CSC); Mineral Trioxide Aggregate insert ignore into journalissuearticles values(MTA); and BiodentineTM when exposed to endodontic irrigating solutions 5% Sodium hypochlorite insert ignore into journalissuearticles values(NaOCl); or 2% Chlorhexidine insert ignore into journalissuearticles values(CHX);. Materials and Methods: A total of 60 insert ignore into journalissuearticles values(n=30); cylindrical samples insert ignore into journalissuearticles values(10 mm diameter, 2 mm height); were prepared by manipulating white MTA Angelus insert ignore into journalissuearticles values(Angelus, Londrina, PR, Brazil); and BiodentineTM insert ignore into journalissuearticles values(Septodent, Saint Maur, France); according to manufacturer`s instructions. These samples were immersed in 5% sodium hypochlorite insert ignore into journalissuearticles values(Prime Dental Products Pvt. Ltd.,Mumbai, India);, 2% chlorhexidine gluconate insert ignore into journalissuearticles values(Dentochlor, Saronno VA, Italia);, or distilled water for 24 hours. Color changes were measured using UV spectrophotometer insert ignore into journalissuearticles values(UV-1650, Shimadzu, Europe); and the values were tabulated. Results: A significant difference was observed between group I and II with respect to both parameters A & B insert ignore into journalissuearticles values(p<0.05);. Both the calcium-silicate-based materials exhibited significant discoloration when immersed in NaOCl and CHX. Distilled water did not cause clinically perceptible discoloration of any material. Conclusions: A significant discoloration was observed with a specific combination of calcium-silicate-based cement and irrigant. BiodentineTM exhibited significant discoloration with CHX whereas, MTA showed more discoloration with NaOCl.
