What does the term 'septum' refer to in the context of a dental dam?

The term 'septum' in the context of a dental dam refers to the area between the holes in the dental dam. This area is essential because it helps to isolate the operative field by providing a barrier between adjacent teeth and the surrounding soft tissues. The septum allows for easier access to the tooth being treated while minimizing contamination from saliva and other fluids, which is crucial for many dental procedures.

This understanding is important for maintaining a dry field and ensuring that restorative materials bond effectively to the tooth structure. Recognizing the role of the septum can enhance the efficiency of dental procedures, making it a key concept in the use of dental dams in practice.
