开发了一种连续流动系统，以评价变形链球菌ATCC 25175与填充材料（Ariston、Tetric、Dyract、Compoglass、Vitremer、Aqua Ionofil、Ketac Fil、汞合金、Galloy和陶瓷作为对照）的粘附性。将变形链球菌添加到唾液包被的测试样本中，并在48 h的时间段内永久供应营养肉汤，然后测定噬菌斑的重量、粘附于材料的细菌的数量和活力。所有充填材料上的人工菌斑重量均高于陶瓷，玻璃离子聚合物上的人工菌斑重量最高。菌斑数量与表面粗糙度相关，而表面粗糙度与S.变异人粘附的S.变形杆菌的存活能力也取决于细菌的存活能力。Ketac Fil上的菌斑含有大量活菌。玻璃离聚体的氟化物不能有效地阻止S.变异体
A continuous flow system was developed to evaluate the adhesion of Streptococcus mutans ATCC 25175 to filling materials (Ariston, Tetric, Dyract, Compoglass, Vitremer, Aqua Ionofil, Ketac Fil, amalgam, Galloy and ceramics as controls). Streptococcus mutans was added to saliva-coated test specimens, and a nutrient broth permanently supplied over a time period of 48 h and then the weight of plaque, the number and viability of the bacteria adhering to the materials were determined. The weights of artificial plaque on all filling materials tested were higher than those on ceramics, the highest values were measured on the glass-ionomers. The amount of plaque correlates with the surface roughness, whereas there was no correlation of the surface roughness with the number of colony-forming units (CFU) of S. mutans. The CFU of adhering S. mutans also depends on the viability of the bacteria. The plaque on Ketac Fil contained a high number of viable bacteria. The fluorides of glass-ionomers do not efficiently prevent the attachment and the viability of S. mutans.
