Dental Dams

Definition : Dental dams are thin square or rectangular sheets used by dentists to isolate a tooth or teeth during dental or endodontic procedures. They usually range in size between 4 in. to 6 in. (10 cm to 15 cm), come in various colors, and are made of natural rubber latex or of elastic plastomers (polymer material which combines qualities of elastomers and plastics) for use with patients and staff who are sensitive to latex. To place the dental dam, a hole is punched in the dental dam to allow placement around the tooth or teeth undergoing treatment, and the dam is placed in a frame and clamped to the tooth or teeth, which holds the dam in place within the patient's mouth during the procedure. Some dental dams are manufactured with built-in flexible frames. They are used in dentists' offices to minimize the risk of contamination by bacteria from the fluids of the mouth, to provide a clean operating field, and to prevent aspiration by the patient of dental materials, irrigants, or instruments.
