Abstract:

A hollow U-shaped rubber dam device which eliminates the need for a dental assistant to handle a suction tube to maintain a dry field of work and prevent water from a dental drill from running uncontrollably over the patient by providing a structure which by itself maintains a dry field for dental work. The device is constructed so as to provide a suction path through the hollow interior for connection to the standard suction coupling of a dental stand, and to accept the standard dental suction tube fitting as an easily attachable and detachable part. The hollow interior suction path includes means for cleaning out and sterilizing the interior passages formed within a portion of the body of the device. The device is suitably made of radio-transparent material, such as molded plastic, and may remain in place while X-rays are taken without producing shadows on the exposed X-ray film.
