PurposeThe aim of present study was to evaluate the color stability of calcium-silicate based cements (CSC) Mineral Trioxide Aggregate (MTA) and BiodentineTM when exposed to endodontic irrigating solutions 5% Sodium hypochlorite (NaOCl) or 2% Chlorhexidine (CHX).Materials and MethodsA total of 60 (n=30) cylindrical samples (10 mm diameter, 2 mm height) were prepared by manipulating white MTA Angelus (Angelus, Londrina, PR, Brazil) and BiodentineTM (Septodent, Saint Maur, France) according to manufacturer's instructions. These samples were immersed in 5% sodium hypochlorite (Prime Dental Products Pvt. Ltd., Mumbai, India), 2% chlorhexidine gluconate (Dentochlor, Saronno VA, Italia), or distilled water for 24 hours. Color changes were measured using UV spectrophotometer (UV-1650, Shimadzu, Europe) and the values were tabulated.ResultsA significant difference was observed between group I and II with respect to both parameters A & B (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.ConclusionA significant discoloration was observed with a specific combination of calciumsilicate-based cement and irrigant. BiodentineTM exhibited significant discoloration with CHX whereas, MTA showed more discoloration with NaOCl.
