Expiration Date: December 31, 2019

Globally, viral, bacterial, and fungal diseases have been emerging at an alarming rate since the 1980s. Among the most worrisome are bloodborne diseases such as AIDS, caused by HIV, and viral hepatitis B, C, D, and G. Antibiotic-resistant strains of bacteria and fungus are increasing in frequency and are becoming more resistant to the currently available antimicrobial agents. The best approach to reducing the risk of infection transmissions in the dental office is the use of universal precautions. This method includes the standard precautions of hand washing, use of personal protective equipment, proper cleaning and disinfection, and injury prevention. However, even with these precautions in place, the bioaerosol generated during dental procedures is responsible for the dissemination of many organisms.

This basic-level course discusses the issue of bioaerosol and reviews interventions that can dramatically reduce bioaerosol contamination during the delivery of oral care. Dentists, dental hygienists, and dental assistants can benefit from the overview of the risks of contamination associated with bioaerosol. This course discusses management of dental unit waterline contamination and suggests appropriate dental equipment necessary for providing sterile water for oral surgical procedures. Finally, the course reviews the importance of preprocedural rinsing as a step in reducing the potential for infection for both practitioner and patient.
