How does the use of a dental dam contribute to infection control?

Using a dental dam plays a significant role in infection control primarily because it helps isolate the area of treatment from the patient's saliva. This isolation is crucial as saliva can contain various pathogens that may pose an infection risk to both the patient and the dental team. By creating a barrier, a dental dam minimizes the chances of saliva splatter during procedures, significantly reducing the potential for cross-contamination and the spread of infectious agents.

In addition to enhancing infection control, dental dams can also improve visibility for the dental practitioner and facilitate a more efficient workflow. However, the primary benefit in the context of infection control is its ability to effectively separate the working environment from the contaminants found in saliva. This function is essential for maintaining a safe and hygienic environment during dental treatments.
