This study aimed to evaluate the color stability and solubility of Biodentine and NeoPutty in contact with different irrigation solutions.
Biodentine and NeoPutty were set in cylindrical molds with 7 mm diameter and 1.5 mm high and immersed in distilled water, 17% ethylenediaminetetraacetic acid (EDTA), 2% chlorhexidine (CHX), 9% 1-hydroxyethylidene 1,1-diphosphonate (HEDP), and 5% sodium hypochlorite (NaOCl) solutions for 24 hours. The color change was measured with a spectrophotometer. The solubility values were calculated as the mass loss was expressed as a percentage of the original mass using an analytical balance with 10 g accuracy. Data were analyzed with Kruskal-Wallis followed by Mann-Whitney tests, and 2-way analysis of variance test followed by Bonferroni corrections for pairwise comparisons for solubility and color stability with a 5% significance threshold, respectively.
Biodentine exhibited higher color changes compared to the NeoPutty contact with all solutions except distilled water ( < 0.05). Both hydraulic cements (HCs) showed higher discoloration values immersion in CHX followed by NaOCl. No statistically significant difference was found between Biodentine and NeoPutty regardless of irrigation solution in terms of solubility ( > 0.05). Solubility values were lower in the distilled water group compared to EDTA and CHX ( < 0.05).
Tested HCs showed solubility and color changes at various rates. NeoPutty could be an appropriate material in aesthetic areas. The usage of HEDP as an irrigant solution can be considered suitable for various endodontic treatments due to its relatively lower solubility and discoloration values.
本研究旨在评估生物陶瓷（Biodentine）和新型根管封闭剂（NeoPutty）与不同冲洗液接触时的颜色稳定性和溶解性。
将生物陶瓷和新型根管封闭剂置于直径7mm、高1.5mm的圆柱形模具中，分别浸泡于蒸馏水、17%乙二胺四乙酸（EDTA）、2%氯己定（CHX）、9% 1-羟基亚乙基二膦酸（HEDP）和5%次氯酸钠（NaOCl）溶液中24小时。用分光光度计测量颜色变化。溶解度值通过使用精度为10g的分析天平，将质量损失表示为原始质量的百分比来计算。数据采用Kruskal-Wallis检验，随后进行Mann-Whitney检验，以及双向方差分析，随后分别对溶解度和颜色稳定性进行Bonferroni校正以进行两两比较，显著性阈值为5%。
与新型根管封闭剂相比，除蒸馏水外，生物陶瓷与所有溶液接触时颜色变化更大（P<0.05）。两种水硬性水泥（HCs）浸泡于CHX后变色值更高，其次是NaOCl。无论冲洗液如何，生物陶瓷和新型根管封闭剂在溶解度方面均无统计学显著差异（P>0.05）。蒸馏水组的溶解度值低于EDTA和CHX组（P<0.05）。
测试的水硬性水泥显示出不同速率的溶解度和颜色变化。新型根管封闭剂可能是美学区域的合适材料。由于其相对较低的溶解度和变色值，HEDP作为冲洗液可被认为适用于各种根管治疗。
