Five commonly used types of orthodontic plier of similar design, but different manufacture were evaluated for wear and corrosion following a 6-month regime of routine use in a hospital department together with steam autoclaving in a centralized unit. Three different types of manufacture (metal finish) were evaluated: (1) a stainless steel plier; (2) a chrome plated plier; and (3) a cheaper chrome plated plier. Four identical kits for changing archwires were assembled for each of the three manufacture types. A sixth 'plier', always of chrome plated manufacture (group 2) was added to every kit and acted as an additional control. In all, 72 pliers were evaluated by three observers immediately before and after the trial. Visual analogue and rank scales were used to assess corrosion, damage, the efficiency of the plier, etc. Generally, all of the pliers stood up well to a combination of routine clinical use and steam autoclaving; however, the stainless steel pliers appeared to perform the best. It is likely that the most important factor, when setting up this type of sterilizing method for orthodontic instruments, is to establish a careful and meticulous routine for cleaning, lubricating, and steam autoclaving pliers.
对五种设计相似但制造商不同的常用正畸钳进行了评估，这些正畸钳在医院科室经过6个月的常规使用，并在中央单元进行蒸汽高压灭菌后，观察其磨损和腐蚀情况。评估了三种不同类型的制造商（金属表面处理）：（1）不锈钢钳；（2）镀铬钳；（3）较便宜的镀铬钳。针对三种制造商类型中的每一种，组装了四个相同的用于更换弓丝的套件。每个套件中都添加了第六个“钳子”，其始终为镀铬制造（第2组），作为额外的对照。总共72把钳子在试验前后由三名观察者进行了评估。使用视觉模拟量表和等级量表来评估腐蚀、损坏、钳子的效率等。总体而言，所有钳子在常规临床使用和蒸汽高压灭菌的综合作用下表现良好；然而，不锈钢钳似乎表现最佳。在为正畸器械设置这种灭菌方法时，最重要的因素可能是建立一套仔细且细致的钳子清洁、润滑和蒸汽高压灭菌程序。
