What is the purpose of using a dental dam during a procedure?

Using a dental dam during a procedure serves several key purposes, and one of the primary functions is to prevent contamination from saliva. By isolating the teeth that are being worked on, the dental dam creates a dry working field that minimizes the presence of saliva and blood, which can interfere with the procedure. This isolation allows for better visibility of the treatment area and helps ensure that dental materials adhere properly, thus improving the overall outcome of the treatment.

While enhancing visibility, reducing patient anxiety, and simplifying the procedure may be secondary effects or benefits of using a dental dam, they are not the primary purpose. The main intention is to maintain a clean and uncontaminated environment to protect both the patient’s health and the integrity of the dental procedure being performed.
