Which usage is not commonly associated with rubber dams?

Rubber dams are primarily used in dentistry to create a dry and isolated working area, making them particularly beneficial for various procedures. In root canal treatment, they are essential as they prevent saliva and other fluids from contaminating the canal system, ensuring a cleaner working environment. Similarly, during restorations, rubber dams help in keeping the tooth dry and free from moisture, which is crucial for the adhesion of materials used in fillings.

When it comes to sealants, the use of a rubber dam can also be advantageous as it protects the treated area from saliva, enhancing the effectiveness of the sealant application.

However, oral surgery is less commonly associated with rubber dam usage. Typically, during oral surgical procedures, the focus is on access to the surgical site, and other methods for managing saliva and moisture, such as suction techniques or other isolation methods, are often preferred. Oral surgery might require wider access, making the rubber dam less practical or feasible compared to other methods. Therefore, the least common use of rubber dams within the options presented is associated with oral surgery.
