What must a dental assistant initiate to prevent contact with pathogens?

The correct choice to prevent contact with pathogens is the implementation of barrier techniques. Barrier techniques involve the use of protective equipment such as gloves, masks, face shields, and gowns to create a physical separation between the dental assistant and potential infectious agents. By using these barriers, dental assistants can minimize direct exposure to blood, saliva, and other potentially infectious materials. This is a fundamental practice in infection control within dental settings, as it directly addresses the risk of pathogen transmission during patient care.

Utilizing barrier techniques is essential not only for personal protection but also for safeguarding patient health. Through proper application of these techniques, dental professionals can create a safer environment, reducing the likelihood of cross-contamination. This is particularly crucial in a clinical setting where exposure to infections is a constant concern.

While physical barriers, disinfection protocols, and isolation procedures also play significant roles in infection control, barrier techniques specifically focus on preventing direct contact with pathogens, making them the most appropriate initial step in this context.
