Fine aerosolised droplets and splatter generated during dental procedures influences the composition of the indoor air quality of dental care facilities and poses a potential threat to the workers' health. Therefore there is a need to assess the risks from exposure to bioaerosols and splatter and identify measures of reducing possible hazards.
A review of the literature related to occupational exposure and health hazards in dentistry was conducted. The search primarily focused on endotoxin exposure from contaminated dental unit waterlines.
This review highlights the various occupational hazards experienced by dental personnel. However, focus is directed on exposure to biological agents as a result of fine aerosol and splatter generated from dental procedures. More emphasis is on endotoxin exposure from contaminated dental unit waterlines and the negative impact it may have on dental workers. The review also aims to inform the reader of proposed endotoxin levels in both air and water and how and by whom it should be measured.
Understanding the main sources of endotoxin in dental practice and its influence on indoor air and potential threat to dental workers is pertinent to infection control strategies.
牙科诊疗过程中产生的细微雾化飞沫和飞溅物会影响牙科护理设施室内空气质量的构成，并对工作人员的健康构成潜在威胁。因此，有必要评估接触生物气溶胶和飞溅物的风险，并确定降低潜在危害的措施。
对与牙科职业暴露和健康危害相关的文献进行了综述。搜索主要集中在受污染的牙科设备水管中的内毒素暴露。
本综述强调了牙科人员所面临的各种职业危害。然而，重点关注的是牙科诊疗过程中产生的细微气溶胶和飞溅物导致的生物制剂暴露。更加强调受污染的牙科设备水管中的内毒素暴露及其可能对牙科工作人员产生的负面影响。该综述还旨在告知读者空气中和水中的内毒素建议水平，以及应如何测量以及由谁来测量。
了解牙科实践中内毒素的主要来源及其对室内空气的影响以及对牙科工作人员的潜在威胁，对于感染控制策略至关重要。
