An experimental system of laboratory infection control was tested, using 76 dentures from 40 volunteer patients. The dentures were cleansed on entering and again on leaving the laboratory. To evaluate the effectiveness of disinfection, the dentures were cultured as they were received from the patient, after the first cleansing, after polishing, and after the second cleansing. The disinfection of the prostheses involved scrubbing them with Hibiclens skin cleanser, rinsing, disinfection in one of three disinfectants (1:16 Sporicidin solution, full-strength Sporicidin solution, and 5.25% sodium hypochlorite [undiluted Clorox]), and finally rinsing. Full-strength Sporicidin solution was significantly more effective than diluted Sporicidin solution, but no statistically significant difference was found between full-strength Sporicidin solution and sodium hypochlorite, or between sodium hypochlorite and 1:16 Sporicidin solution. All three solutions were effective in reducing or eliminating culturable aerobic bacteria.
使用来自40名志愿者患者的76副假牙，对实验室感染控制的一个实验系统进行了测试。假牙在进入实验室时进行清洁，离开实验室时再次清洁。为了评估消毒效果，在从患者处收到假牙后、第一次清洁后、抛光后以及第二次清洁后对假牙进行培养。假体的消毒包括用洗必泰皮肤清洁剂擦洗、冲洗、在三种消毒剂之一（1:16的斯波立西定溶液、原液斯波立西定溶液和5.25%次氯酸钠[未稀释的高乐氏]）中消毒，最后冲洗。原液斯波立西定溶液比稀释的斯波立西定溶液显著更有效，但在原液斯波立西定溶液和次氯酸钠之间，或次氯酸钠和1:16斯波立西定溶液之间未发现统计学上的显著差异。所有三种溶液在减少或消除可培养需氧菌方面均有效。
