The main function of a dental dam is to control what?

The primary function of a dental dam is to control moisture during dental procedures. By creating a barrier that isolates the operative site from the saliva and other fluids in the mouth, dental dams help maintain a dry working area. This is crucial for many restorative and endodontic procedures where moisture can compromise material adhesion, result in contamination, and negatively affect the overall outcome of the treatment.

Maintaining a dry field is essential not only for the effectiveness of certain dental materials but also for ensuring the precision necessary for procedures like root canals or placing fillings. Excess moisture can lead to complications such as failure of the bonding process or increased risk of infection.

While visibility, patient comfort, and access to teeth are important considerations in dental procedures, they are secondary benefits resulting from the use of a dental dam. The primary focus remains on moisture control, which is fundamental to achieving successful treatment outcomes.
