Abstract

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.

摘要

目的

评估 BioRoot RCS（粉液型）和 BioRoot Flow（预混型）在暴露于柠檬酸（CA）和 EDTA 后的理化性能。

方法

BioRoot RCS 和 BioRoot Flow 试件（5×2mm）在 37°C 下孵育 28 天后，用测试溶液（蒸馏水、17% EDTA、10% CA、20% CA 或 40% CA）处理。评估质量变化、离子释放（电感耦合等离子体发射光谱法）、物相组成（X 射线衍射和拉曼光谱法）、表面形貌（扫描电子显微镜和能量色散光谱法）。采用 Shapiro-Wilk、Levene 和单因素方差分析，随后进行 Tukey 检验，进行统计学分析（p<0.05）。

结果

BioRoot RCS 和 BioRoot Flow 的最大质量损失、离子释放和表面形貌变化（孔和裂纹）发生在 10%和 20% CA 中。在蒸馏水中和 EDTA 中，BioRoot RCS 和 BioRoot Flow 之间没有显著差异（p>0.05），而在所有 CA 溶液中，BioRoot Flow 的溶解度明显高于 BioRoot RCS（p<0.001）。两种材料的主要相均为氧化锆，该相不受溶液影响。
