What is the name of the dental dam material located between the holes?

The section of the dental dam material that is situated between the holes is referred to as the septum. The septum serves an important function as it helps maintain the integrity of the dam, ensuring that the isolated area remains dry and free from contamination during dental procedures. This area is crucial for effective moisture control, as it minimizes saliva and other fluids from interfering with the treatment being conducted in the exposed tooth or teeth.

In contrast, the clamp is a device used to secure the dental dam in place, typically around the tooth being treated, providing stability. The stylus is not a part of the dental dam but rather an instrument used in dental procedures, such as marking or tracing. An isolator may refer to a different type of dental tool or technique used for isolation, but it does not specifically denote the section of the dam material itself. Understanding these distinctions is essential for effective dental practice, especially regarding moisture control.
