In congregate living settings when active coronavirus disease 2019 (COVID-19) transmission is present, limiting the scope of dental care to urgent and emergent treatment minimizes exposure risk for patients and staff. Engineering controls to mitigate aerosol production during dental procedures, including enhanced high-volume evacuation, high-efficiency particulate absorbing air filtration, and the use of a dental dam provide additional protection for dental providers and staff. Properly fitted N-95 respirators are of particular importance to limit COVID-19 transmission when SARS-CoV-2 containing aerosols may be present. When patients are known to be COVID-19 positive, the use of powered air-purifying respirators is appropriate. Further protection against the spread of disease among patients and staff may be provided by point-of-care testing for patients prior to dental procedures during outbreaks.

国家监狱系统牙科治疗期间 COVID-19 的缓解。

在存在活动性冠状病毒病 2019 (COVID-19) 传播的聚集生活环境中，将牙科护理的范围限制为紧急和急诊治疗可最大限度地降低患者和工作人员的接触风险。减少牙科手术过程中气溶胶产生的工程控制，包括加强大容量疏散、高效微粒吸收空气过滤和使用牙科屏障，为牙科提供者和工作人员提供额外保护。当可能存在含有 SARS-CoV-2 的气溶胶时，正确安装的 N-95 呼吸器对于限制 COVID-19 的传播尤为重要。当已知患者为 COVID-19 阳性时，使用电动空气净化呼吸器是合适的。
