Final answer:
Inverting rubber dams is a dental procedure to isolate a tooth, keeping it dry and free from contaminants during treatment, not to interact with antibodies or interstitial fluids.
Step-by-step explanation:
The purpose of inverting rubber dams is not to allow antibodies to enter infected cells or to prevent the diffusion of fluid into the interstitial space. Typically, in dental procedures, rubber dams are inverted to create a seal around the tooth to isolate it from the rest of the mouth.
This isolation helps to keep the area clean, free from saliva, and clear of other contaminants during dental procedures, such as fillings or root canals. It's critical for maintaining a sterile field and ensuring that the treatment area remains dry.
