This study has assessed the durability of four brands of latex gloves, Ansell Medical 'Medi-Grip', Regent 'Biogel D', Surgikos 'Microtouch' and the London Rubber Company 'Supreme', under conditions of repeated washing and re-use in a clinical dental setting. The microbiological effectiveness of 'Hibiscrub' as a decontaminating washing agent was examined simultaneously. Examination by an electrical test for micropunctures in 200 unused gloves of each brand revealed such defects in 6(3%) of Ansell 'Medi-Grip', 3(1.5%) of 'Biogel D', 14(7%) of Surgikos 'Microtouch' and 2(1%) of LRC 'Supreme' gloves. Following repeated clinical use, micropunctures were detected in 18% of Ansell 'Medi-Grip', 10% of 'Biogel D', 75% of Surgikos 'Microtouch' and 56% of LRC 'Supreme'. Microorganisms were isolated from the glove surfaces after 45% of the occasions on which the gloves were washed for 1 min in 'Hibiscrub' (ICI Dental). Eighty-five per cent of these isolates were environmental organisms, but oral streptococci were isolated from 8.4% of the pairs of gloves examined. The high rate of micropuncture development following repeated washing and re-use of latex gloves indicates that they cannot effectively perform their barrier function under such conditions. The microbiological data have also revealed the potential for cross-infection between patients through inadequate decontamination of glove surfaces. For operative dental surgery, the results suggest that heavier, surgical type gloves are to be preferred, and that multiple use of any glove type should be discouraged.
本研究评估了安塞尔医疗公司的“Medi - Grip”、丽晶公司的“Biogel D”、外科手术用品公司的“Microtouch”以及伦敦橡胶公司的“Supreme”这四个品牌的乳胶手套在临床牙科环境中反复清洗和重复使用条件下的耐用性。同时还检测了“洗必泰醇”作为去污清洗剂的微生物学效果。通过对每个品牌200只未使用手套进行微穿刺的电气测试检查发现，安塞尔“Medi - Grip”手套中有6只（3%）存在此类缺陷，“Biogel D”手套中有3只（1.5%），外科手术用品公司的“Microtouch”手套中有14只（7%），伦敦橡胶公司的“Supreme”手套中有2只（1%）。在反复临床使用后，安塞尔“Medi - Grip”手套中有18%检测到微穿刺，“Biogel D”手套中有10%，外科手术用品公司的“Microtouch”手套中有75%，伦敦橡胶公司的“Supreme”手套中有56%。在用“洗必泰醇”（帝国化学工业公司牙科产品）对手套进行1分钟清洗的45%的情况下，从手套表面分离出了微生物。这些分离出的微生物中，85%是环境微生物，但在8.4%的被检查手套对中分离出了口腔链球菌。乳胶手套在反复清洗和重复使用后微穿刺发生率很高，这表明它们在这种条件下无法有效发挥屏障功能。微生物学数据还揭示了手套表面去污不充分可能导致患者之间交叉感染的可能性。对于口腔外科手术，结果表明应首选更厚的手术用手套，并且不鼓励对任何类型的手套进行多次使用。
