背景
大多数在放置和移除汞合金修复体过程中产生的汞合金颗粒都会被椅边捕集器以及抽吸系统捕集器和过滤器捕获。未被捕获的颗粒最终可能会进入牙科诊所排出的废水中。旨在减少向环境中排放牙科汞合金废物等含汞产品的环保举措引发了人们对使用汞合金分离器的兴趣。
方法
作者在实验室测试中使用国际标准化组织 (ISO) 汞齐分离器标准 11,143 来评估 13 种市售汞齐分离器和两种市售过滤装置（未作为汞齐分离器销售但有潜力用作汞齐分离器）的汞齐去除效率。
结果
所有 13 个汞齐分离器和两个过滤装置均超过了 ISO 标准 11,143 95% 汞齐去除效率的要求。作者发现分离器和过滤装置的效率存在统计差异。每个分离器的“空”和“满”条件之间没有发现差异。
结论和临床意义
该实验室评估表明，汞齐分离器和过滤装置去除了样品中至少 97.05% 的汞齐，其粒度分布符合 ISO 标准 11,143 的规定。
BACKGROUND
Most amalgam particles generated during placement and removal of amalgam restorations are captured by chair-side traps and suction system traps and filters. Particles not captured can end up in the wastewater discharged from the dental office. Environmental initiatives to reduce the discharge of mercury-containing products such as dental amalgam waste into the environment have sparked interest in the use of amalgam separators.
METHODS
The authors used International Organization for Standardization (ISO) Standard 11,143 for Amalgam Separators in a laboratory test to evaluate the amalgam removal efficiency of 13 commercially available amalgam separators and two commercially available filtration devices not marketed as amalgam separators but that have the potential to be used as such.
RESULTS
All 13 amalgam separators and the two filtration devices exceeded the ISO Standard 11,143 requirement of 95 percent amalgam removal efficiency. The authors found statistical differences in the efficiency of the separators and filtration devices. No differences were found between the "empty" and "full" conditions for each separator.
CONCLUSION AND CLINICAL IMPLICATIONS
This laboratory evaluation shows that amalgam separators and the filtration devices removed at least 97.05 percent of the amalgam in samples with particle-size distribution as specified in ISO Standard 11,143.
