The impact of various irrigation solutions on the color stabilities of five calcium silicate cement: an in-vitro study

Background: This in-vitro examine aimed to determine the color changes of five calcium silicate cement [wMTA Angelus(wMTA), Biodentine (BD), Neo MTA Plus, Retro MTA, Ortho MTA] in various irrigation solutions. Methods: A total of 100 samples (n=20) were homogenously mixed and placed in cylindrical specimens (diameter of 10 mm and height of 2 mm). After setting time, the color of the samples was analyzed by using a spectrophotometer (VITA Easyshade V, Vita Zahnfabrik, Bad Sackingen, Germany). Later, each specimen was immersed in 5.25% Sodium hypochlorite (NaOCl), 2% Chlorhexidine gluconate (CHX), 17% Etilendiamin tetraacetic asit (EDTA), and Saline for 24 hours, and 20 samples were left dry. Color changes were calculated. Compliance with normal distribution was assessed using the Shapiro-Wilk test. The comparison of color values, which were not normally distributed, according to material and solution, was analyzed using a two-way robust ANOVA, and multiple comparisons were examined with the Bonferroni test. Statistical significance was p < 0.05. Results: The color change of wMTA Angelus was higher than that of the other materials when immersed with NaOCl. Neo MTA Plus revealed the highest color change when immersed in EDTA. The maximum discoloration of BD was observed when immersed in CHX. Conclusion: RetroMTA may be a better choice because of less discoloration in the clinic routine.
