Plaque material collected from margins of restorations using a sharp toothpick was streaked across one and the same plastic strip from a commercially available test kit and inoculated in a liquid medium containing bacitracin. The reproducibility of the method was good. The method is simple, inexpensive and suitable for the chairside demonstration of the colonization of mutans streptococci in localized areas of the mouth, such as margins of restorations.
使用尖锐牙签从修复体边缘采集菌斑样本，将其在市售检测试剂盒中的同一条塑料条上划线，并接种于含有杆菌肽的液体培养基中。该方法的可重复性良好。该方法简单、成本低，适用于在口腔局部区域（如修复体边缘）进行变异链球菌定植情况的椅旁演示。
