摘要

目的评估 BioRoot RCS(粉液制剂)和 BioRoot Flow(预混制剂)暴露于柠檬酸(CA)和 EDTA 后的物理化学特性:将 BioRoot RCS 和 BioRoot Flow 试样(5 × 2 毫米)在 37 °C 下培养 28 天,然后用测试溶液(蒸馏水、17% EDTA、10% CA、20% CA 或 40% CA)进行处理。对质量、离子释放(电感耦合等离子体光发射光谱)、相组成(X 射线衍射和拉曼光谱)、表面形态(扫描电子显微镜和能量色散光谱)的变化进行了评估。采用 Shapiro-Wilk、Levene 和单因子方差分析以及 Tukey 检验进行统计分析(p 结果:BioRoot RCS 和 BioRoot Flow 的最大质量损失、离子释放和表面形态变化(孔隙和裂缝)出现在 10% 和 20% CA 中。在蒸馏水和 EDTA 溶液中,BioRoot RCS 和 BioRoot Flow 之间没有发现明显差异(p > 0.05),而在所有 CA 溶液中,BioRoot Flow 的溶解度明显高于 BioRoot RCS(p 结论:BioRoot RCS 和 BioRoot Flow 在所有 CA 溶液中的溶解度均高于 BioRoot RCS:在研究范围内,10% 和 20% CA 对生物根 RCS 和生物根流的溶解效果优于蒸馏水、17% EDTA 和 40% CA。BioRoot Flow 在所有 CA 溶液中的溶解度都明显高于 BioRoot RCS。临床意义:10% 和 20% 的 CA 溶液有可能在牙髓再治疗过程中用作液压硅酸钙封闭剂的溶剂。

A laboratory study to assess the physico-chemical properties of BioRoot RCS and BioRoot Flow exposed to citric acid and EDTA irrigating solutions.

Objective: To assess physico-chemical properties of BioRoot RCS (powder-to-liquid formulation) and BioRoot Flow (pre-mixed formulation) after exposure to citric acid (CA) and EDTA.

Methods: BioRoot RCS and BioRoot Flow specimens (5 × 2 mm) were incubated for 28 days at 37 °C before being treated with test solution (distilled water, 17% EDTA, 10% CA, 20% CA or 40% CA). Changes in mass, ion release (inductively coupled plasma optical emission spectroscopy), phase composition (X-ray diffraction and Raman spectroscopy), surface morphology (scanning electron microscopy and energy dispersive spectroscopy) were evaluated. The Shapiro-Wilk, Levene and one-way ANOVA, followed by Tukey's test, were used for statistical analysis (p < 0.05).

Results: The greatest mass loss, ion release and surface morphological changes (pores and cracks) of BioRoot RCS and BioRoot Flow occurred in 10% and 20% CA. No significant differences were identified between BioRoot RCS and BioRoot Flow in distilled water and EDTA (p > 0.05), whereas BioRoot Flow was significantly more soluble than BioRoot RCS in all CA solutions (p < 0.001). The main phase identified for both materials was zirconium oxide, which remained unaffected by the solutions.

Conclusions: Within the limitations of the study, 10% and 20% CA were more effective than distilled water, 17% EDTA and 40% CA in terms of dissolving BioRoot RCS and BioRoot Flow. The BioRoot Flow was significantly more soluble in all CA solutions than BioRoot RCS.

Clinical significance: 10% and 20% CA solutions may have a potential to be used as a solvent for hydraulic calcium silicate sealers during endodontic retreatment.
