This study aims to evaluate the effect of the special anti-washout gel mixing agent on the color stability of mineral trioxide aggregate (MTA) Plus and NeoMTA Plus in contact with distilled water, ethylenediaminetetraacetic acid (EDTA) and sodium hypochlorite (NaOCl).
One set of three specimens was mixed using the antiwashout gel and the other set of three specimens was mixed using distilled water. Then, one specimen from each group was immersed in distilled water, 5% NaOCl or EDTA solutions for 24 hours. The color change of each specimen was assessed using spectrophotometer. The data were evaluated statistically with two-way ANOVA and post-hoc Tukey tests.
MTA Plus mixed with gel showed the highest color stability regardless of the solution type.
Mixing with MTA Plus and NeoMTA Plus powder with the special anti-washout gel within their kits contributes to the color stability of the materials.
