BACKGROUND
This study evaluated the effect of nano-silica (NS) incorporation with resin infiltrant on water sorption and solubility of resin infiltrant, mineral density of demineralized enamel, and resin tags penetration.
METHODS
NS (Sigma-Aldrich, St Louis, Missouri, USA) was added into the resin infiltrant (ICON, DMG, Hamburg, Germany) at two concentrations by weight. The tested groups were: ICON (control), ICON + 0.2, and ICON + 0.5 (n = 10 per group). Water sorption and solubility were assessed using mass variation after 60 days water storage. Mineral density and surface topography were assessed using micro-Computed Tomography scans. Resin tags penetration was measured using a scanning electron microscope. Data were analyzed using one-way Analysis of Variance and Tukey's post-hoc tests (P < .05).
RESULTS
ICON revealed the highest water sorption, solubility mean values (28.90, 7.61) followed by ICON + 0.2 (14.80, 4.82) and ICON + 0.5 (12.32, 0.81) respectively, and vice versa for resin tags penetration. Mineral density of demineralized enamel significantly increased after treatment with ICON + 0.2 and ICON + 0.5.
CONCLUSION
Incorporation of NS to resin infiltrant decreased its water sorption and solubility along with enhancing the mineral density of the demineralized enamel and the penetration of resin tags.
背景
本研究评估了纳米二氧化硅（NS）与树脂渗透剂结合对树脂渗透剂的吸水性和溶解性、脱矿釉质的矿物质密度以及树脂标签渗透的影响。
方法
将NS（美国密苏里州圣路易斯市西格玛奥德里奇公司）按两种重量浓度添加到树脂渗透剂（德国汉堡DMG公司的ICON）中。测试组分别为：ICON（对照组）、ICON + 0.2和ICON + 0.5（每组n = 10）。储存60天后，通过质量变化评估吸水性和溶解性。使用微型计算机断层扫描评估矿物质密度和表面形貌。使用扫描电子显微镜测量树脂标签的渗透情况。数据采用单因素方差分析和Tukey事后检验进行分析（P < 0.05）。
结果
ICON的吸水性和溶解性平均值最高（分别为28.90、7.61），其次是ICON + 0.2（14.80、4.82）和ICON + 0.5（12.32、0.81），树脂标签渗透情况则相反。用ICON + 0.2和ICON + 0.5处理后，脱矿釉质的矿物质密度显著增加。
结论
将NS加入树脂渗透剂可降低其吸水性和溶解性，同时提高脱矿釉质的矿物质密度和树脂标签的渗透率。
