It has been suggested that gloved hands could be washed between patient treatments in the dental surgery and gloves re-used, provided they are undamaged. A series of experiments are described, which evaluate the effectiveness of four handwashing agents at removing defined bacterial inoculae from two types of latex rubber glove, a dedicated dental procedure glove (Regent Biogel D) which has a rough surface and a smooth-surfaced examination glove (Microtouch). The four agents tested were povidone iodine (Betadine), chlorhexidine (Hibiscrub), 60% iso-propyl alcohol, and a detergent triclosan preparation (Kleenex washcream). The Biogel D gloves required slightly shorter washing times to eradicate organisms than the Microtouch gloves. It was found that washing with water alone reduced the organisms on gloves by 300-1000-fold, but a minimum washing time of 20 seconds with povidone iodine or chlorhexidine was required to eradicate all the organisms inoculated, except bacterial spores, from both glove surfaces. Povidone-iodine and chlorhexidine were more effective washing agents than iso-propyl alcohol and triclosan soap.
有人提出，在牙科手术中，若手套未破损，可在治疗不同患者期间对手套进行清洗并重复使用。本文描述了一系列实验，评估了四种洗手剂从两种乳胶手套上去除特定细菌接种物的效果，这两种手套分别是表面粗糙的专用牙科手术手套（Regent Biogel D）和表面光滑的检查手套（Microtouch）。所测试的四种试剂分别是聚维酮碘（碘伏）、氯己定（洗必泰）、60%异丙醇和一种含三氯生的洗涤剂制剂（舒肤佳洗手膏）。与Microtouch手套相比，Biogel D手套清除微生物所需的洗涤时间略短。结果发现，仅用水冲洗可使手套上的微生物数量减少300 - 1000倍，但要从两种手套表面根除所有接种的微生物（细菌芽孢除外），用聚维酮碘或氯己定至少需洗涤20秒。聚维酮碘和氯己定作为洗手剂比异丙醇和三氯生肥皂更有效。
