Respiratory protection in dentistry.

Respiratory protection in the dental setting has become more important to protect healthcare professionals, their household members and their patients. As dental practices become increasingly independent in managing their respiratory protection requirements, the need for an in-depth understanding of the principles of respiratory protection is warranted. This article aims to enhance the awareness of dental professionals about the principles of respiratory protection and equipment, including designs, classification and levels of protection afforded to wearers. Determining the adequacy and suitability of respiratory protection, along with ensuring safe selection of appropriate equipment for protection of both wearer and patient, is described. Moreover, a detailed review of fit testing principles, procedures and governance are described. This comprehensive review should ensure that dental professionals are ideally placed to understand the implications of respiratory protection and safely apply it in their workplaces.
