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.
A rubber dam is a thin sheet with a hole in the centre, used to isolate a tooth from the fluids in the mouth: the tooth is put through the hole and the sheet is stretched around it. The FDA groups the dam, the clamp, the frame and the clamp forceps as one Class I device (21 CFR 872.6300).
It has been in use since 1864 and is now described as the standard of care, particularly in endodontics. Besides an aseptic and dry working site, it is credited with better visibility, soft tissue retraction, less rinsing, a lower risk of swallowing or inhaling a small part, and protection of the soft tissues from materials.
How the sheet, the frame and the clamp differ
What to look at when choosing a rubber dam
Aerosol: studies have reported that dam isolation reduced bacterial aerosol contamination by up to 98.8 percent at one metre from the working site, and by up to 99.4 percent together with a pre-procedural antiseptic mouth rinse.
Latex: non-latex sheets are described as critical for patients with a latex allergy. Comfort: one trial found patient comfort similar between a conventional non-latex system and a prefabricated non-latex one.
