用含抗菌填料粉末（Apacider-AW, Ap-AW）的树脂复合材料制备V类空腔，并采用实验性修复体进行修复。修复后的牙齿与致龋细菌变形链球菌IFO 13955体外培养。地面部分然后准备和检查使用微距摄影。记录外壁和内壁病变，并测量病变穿透的深度。我们发现，在含有1-5 wt% Ap-AW的修复体中，龋渗透到边缘区域，而在含有10 wt% Ap-AW的修复体中，牙合侧和牙龈侧的边缘距离分别约为1.1和1.8 mm。1997爱思唯尔科学有限公司版权所有。
Class V cavities were prepared and restored with resin composite containing antibacterial filler powder (Apacider-AW, Ap-AW) using experimental restorations. The restored teeth were incubated in vitro with the cariogenic bacteria Streptococcus mutans IFO 13955. Ground sections were then prepared and examined using macrophotography. Lesions of the outer and inner wall were noted, and the depths to which the lesions penetrated were measured. We found that, in restorations containing 1-5 wt% Ap-AW, caries penetrated the marginal area, while in restorations containing 10 wt% Ap-AW the margin remained free of caries out to a distance of about 1.1 and 1.8 mm on the occlusal and gingival sides, respectively.
