Different cleaning procedures affected the mechanical characteristics of elastomeric chains. Hence, 255 samples, divided into 17 groups of 15 samples each, were tested for bacterial contamination and tensile strength using five disinfection procedures. Colonies on culture plates indicated contamination, while the universal testing machine determined ultimate tensile strength. The samples disinfected with 70% isopropyl alcohol (IPA) remained contaminated, as shown by colony growth, even though there was a statistically significant reduction in colonies compared to the controls. All samples examined after 1 and 10 cycles in the disinfectants had higher ultimate tensile strengths than controls.
不同的清洁程序会影响弹性链的机械特性。因此，将255个样本分成17组，每组15个样本，使用五种消毒程序对其进行细菌污染和拉伸强度测试。培养皿上的菌落表明存在污染，而万能试验机测定极限拉伸强度。用70%异丙醇（IPA）消毒的样本仍有污染，如菌落生长所示，尽管与对照组相比菌落数量有统计学意义的减少。在消毒剂中经过1次和10次循环后检测的所有样本的极限拉伸强度均高于对照组。
