本研究旨在评价含有表面预反应玻璃离子（S-PRG）填料的实验糊剂对牙釉质脱矿的抑制作用。7组牛块每天处理2次，连用4 d；实验膏体含有0-30 wt%的S-PRG填料（S00、S01、S05、S10和S30），去离子水（DW）为阴性对照，NaF （MP）为阳性对照。表面用醋酸脱矿3天。微量计算机x射线断层扫描计算矿物质损失（ML）。最后用扫描电子显微镜（SEM）和微聚焦粒子诱导x射线发射（micro-PIXE）对处理后的表面进行了研究。S05、S10和S30的ML显著低于S00、S01和DW (p
This study aimed to evaluate the inhibitory effect of experimental pastes containing surface pre-reacted glass ionomer (S-PRG) fillers on enamel demineralization. Bovine blocks were treated twice a day for 4 days by 7 groups; experimental pastes containing 0-30 wt% S-PRG filler (S00, S01, S05, S10, and S30), deionized water (DW) as negative control, and NaF paste (MP) as positive control. The surfaces were demineralized by acetic acid for 3 days. Mineral loss (ML) was calculated by micro-computed X-ray tomography. The treated surface was finally investigated with scanning electron microscope (SEM) and micro-focused particle induced X-ray emission (micro-PIXE). S05, S10 and S30 demonstrated significantly lower ML than S00, S01 and DW (p
