Introduction: Although calcium silicate-based cements are very successful in healing, they cause esthetic problems and dissatisfaction, especially in anterior teeth because they cause discoloration in the teeth. This study aimed to detect the color changes that occur as a result of contact of BIOfactor mineral trioxide aggregate (MTA) and biodentin with three different irrigation agents. Methods: The materials to be tested (G1: BIOfactor MTA and G2: Biodentin) were prepared as per the manufacturer's directions. The prepared materials were placed in cylindrical molds of 8 mm diameter and 3 mm height and kept in a 37°C oven for 24 h to complete their hardening. Subsequently, the samples were immersed in one of three different irrigation solutions (5% sodium hypochlorite, 17% ethylenediaminetetraacetic acid [EDTA] or saline) for 24 h. After drying, spectrophotometer was utilized to quantify color under consistent laboratory light by the same administrator. Results: Significantly, more color changes were observed in the G1 group compared to the G2 group (P = 0.05). Although color changes were detected in all subgroups of G1 and G2 groups as a result of contact with different irrigation materials, it was determined that these changes were not statistically significant (P > 0.05). The irrigation agent that caused the most discoloration was saline (12.33 ± 6.87) in G1 group and EDTA (7.05 ± 3.48) in G2 group. Conclusion: As a result of this study, significantly more color changes were found in BIOfactor MTA than biodentin. It was found that different irrigation agents did not cause statistically significant color changes.
