摘要
本研究评估了四种硅酸钙封闭剂在超声波活化（UA）后的凝固时间、pH 值、钙离子释放量、溶解度和化学结构。共评估了五种封闭剂：Sealer Plus (SP - 对照组)、Sealer Plus BC (SPBC)、Bio C Sealers (BCS)、Endosequence BC Sealer (EBC) 和 BioRoot RCS (BR)。根据是否使用超声波活化，分为十组：SP、SP/UA、SPBC、SPBC/UA、BCS、BCS/UA、EBC、EBC/UA、BR 和 BR/UA。固化时间根据 ISO 6876:2012 和 ASTM C266-07 规范执行。根据 ISO 6876:2012，评估了 24 小时时的溶解度。在 1、24、72 和 168 小时时评估了 pH 值和钙释放量。拉曼光谱用于评估结构变化。定量数据采用单向方差分析和 Tukey 事后检验（α=5%）。对拉曼光谱结果进行了定性分析。所有封孔剂的凝固时间和溶解度都不受 UA 的影响（p>0.05）。BCS 和 BCS/UA 以及 BR 和 BR/UA 的溶解度最高（p
Effect of ultrasonic activation on setting time, pH and calcium ion release, solubility, and chemical structure of calcium silicate sealers.
This study evaluated the setting time, pH, calcium ion release, solubility, and chemical structure of four calcium silicate sealers after ultrasonic activation (UA). Five sealers were evaluated: Sealer Plus (SP - control); Sealer Plus BC (SPBC), Bio C Sealers (BCS), Endosequence BC Sealer (EBC), and BioRoot RCS (BR). Ten groups were created based on the use or not of ultrasonic activation: SP; SP/UA; SPBC; SPBC/UA; BCS; BCS/UA; EBC; EBC/UA; BR; and BR/UA. Setting time was performed based on ISO 6876:2012 and ASTM C266-07 specifications. Solubility at 24hs, based on ISO 6876:2012. pH and calcium release were evaluated at 1, 24, 72, and 168hs. Raman spectroscopy was used to evaluate structural changes. Quantitative data were analyzed using One-Way ANOVA and Tukey post-hoc test (α=5%). Raman spectroscopy results were qualitatively analyzed. Setting times and solubility of all sealers were not affected by UA (p>0.05). The highest solubility was found for BCS, BCS/UA; and BR, BR/UA (p<0.05). After 24hs, calcium silicate sealers had higher pH than SP and SP/UA (p<0.05). BR and BR/UA had the highest pH at all time points. SP and SP/UA had stable pH at all time points. SP and SP/UA had the lowest calcium release values at all time points (p<0.05). EBC and EBC/UA calcium release significantly differ at 24,72 and 168hs (p<0.05). No chemical changes were observed during Raman spectroscopy. In conclusion, ultrasonic activation affected calcium ion release only for EndoSequence BC Sealer. Ultrasonic activation did not influence the initial and final setting time, solubility, pH, and chemical structure of any investigated sealers.
