About rubber dam sheets

A rubber dam sheet is the dam itself: a thin sheet of latex with a hole in the centre, used to isolate a tooth from fluids in the mouth during a procedure. Latex is named as a possible allergen for some patients, which is why non-latex sheets are made; one paper notes that comparative data on the non-latex versions is still limited. Colour and thickness of the membrane are named among the things that play a part in the choice, alongside operator preference.

The part that covers the mouth and carries the hole.
