Dental dam consisting thin sheets of vulcanized non-cellular rubber, in the form of a square (152 mm x 152 mm) with perpendicular corners. It is presented in different colours (blue, green, etc.) and have a peppermint aroma. It is used in dentistry (mainly in endodontics, fixed prosthetics and general restoration work) to isolate the site of intervention (one or more teeth) from the rest. It is held over an individual tooth or group of teeth with special clamps over the abutment tooth. The dental crown protrudes above the dental dam through individual holes in it, which isolate the target tooth from the rest of the oral cavity, so that the tooth remains dry and more protected from microorganisms. The main functions of the product are to avoid the ingress of saliva at the site or moisture ingress on the fillings during their application and to prevent the ingestion or inhalation of instruments and materials or injuries to the oral cavity
