背景：牙科手机在重复使用前要经过去污过程。彻底清洁是有效灭菌的先决条件，以保证安全和防止交叉感染。目的：为了评估专用于牙科手机的设备提供的清洁效果。方法：PID测试（C），这是由透明材料制成的专利管，旨在取代清洁设备中的手机，人工染色的污垢测试（C）（Browne/STERIS）。使用连接到四种不同受试机器中每个手柄适配器的PID测试（C）进行三次循环：X-Cid 2（C）（Micro-Mega），共9次PID测试（C）; iCare+（C）（NSK），9次PID测试（C）; DAC Universal（C）（W&H），18次PID测试（C）;以及BioDA 80（C）（VR 2 M），24次PID测试（C）。结果：在三种受试清洁器械（X-Cid 2（C）、iCare+（C）和DAC Universal（C））中，所有PID测试（C）均显示内外表面上存在污物测试（C）残留物，表明清洁无效。只有BioDA 80（C）在所有PID测试（C）和阴性双缩脲反应测试结果中显示无残留污渍，使得清洁有效。制造商应根据辛纳圆优化清洗装置参数（将影响清洁过程的有效性的补偿参数分组，例如压力、温度、时间、洗涤剂浓度），以提高清洁效率并使牙科医生能够确保安全。尽管PID测试（C）是唯一一种提供手机专用清洗消毒器清洁效果视觉指示的工具，但制造商应继续开发经改进和验证的工具，以评估清洁效果。(C)2018年，卫生保健感染协会。由爱思唯尔有限公司出版。保留所有权利。
Background: Dental handpieces undergo a decontamination process before reutilization. Thorough cleaning is a prerequisite to effective sterilization, to guarantee safety and prevent cross-infections.Aim: To assess the cleaning efficacy offered by devices dedicated to dental handpieces.Methods: PIDTests(C), which are patented tubes made of transparent material and designed to replace handpieces in cleaning devices, were artificially stained by Soil Test(C) (Browne/STERIS). Three cycles were performed with PIDTests(C) connected to every handpiece adapter in the four different machines tested: X-Cid 2(C) (Micro-Mega) with a total of nine PIDTests(C); iCare+(C) (NSK) with nine PIDTests(C); DAC Universal(C) (W&H) with 18 PIDTests(C); and BioDA 80(C) (VR2M) with 24 PIDTests(C). A visual evaluation and a biuret reaction test were performed.Findings: In three of the tested cleaning devices (X-Cid2(C), iCare+(C) and DAC Universal(C)), all of the PIDTests(C) showed Soil Test(C) residues, on the internal and external surfaces indicating cleaning was ineffective. Only the BioDA 80(C) showed no residual stains on all the PIDTests(C) and negative biuret reaction test results, making the cleaning effective.Conclusions: Manufacturers should optimize the cleaning device parameters, based on the Sinner circle (grouping compensatory parameters which influence the effectiveness of a cleaning process, such as pressure, temperature, time, detergent concentration), to improve cleaning efficacy and enable dental surgeons to ensure the safety. Although PIDTests(C) are the only tool to provide visual indications on the cleaning efficacy of washer-disinfectors dedicated to handpieces, manufacturers should continue with the development of improved and validated tools to assess cleaning efficacy.
