Rubber Dams
First reported use in ~ 1840Dr. S.C. Barnum – USA
Recommended by ALL teaching authorities and professional societies since the 19th Century for ALLendodontic procedures
And for many other dental procedures!!

“One of the most obvious departures from the accepted standard of care(during endodontic treatment)
is the failure to use rubber dam”

Dam Punch
used to create holes , needed to expose the teeth that are to be isolated. The punch’s working end is used to puncture the dam for the correct hole sizes:Size 5 is the largest size used for anterior tooth.Size 4 the next size smaller used for molars.Size 3 is for bicuspids and canines.Size 2 is for maxillary anteriors and incisiors.Size 1 is the smallest size used for mandibularanterior incisors.

Dental forceps
used to place and remove the dental dam clamp. The beaks of the forceps fit into the holes on the clamp’s jaws.The handles have a spring action that allows the forceps, when squeezed, to open up and fit over the tooth. When the handles are released, so is the clamp.

ClampsRubber Dam Equipment
Keep it Simple !!!
clamp is used to stabilize the dental dam. The dam clamp holds the dental dam secure on the end nearest the tooth thatis being treated. Clamps can be ligatedfor security and safety of the patient from swallowing if the clamp becomes dislodged during treatment.

RD placement techniquesSeveral methods: Single tooth isolation and multiple teeth
1. RD and clamp already set-up and placed on tooth together as a unitUsually requires assistance. Stretch the dam material from side to side to secure the corners of the dam on the four projections at the corner of the frame. The rubber dam material should appear baggy on the frame rather than tight to allow easier placement in the oral cavity. Pass the dam and attached frame to the dentist for placement in the oral cavity. As the dentist stretches the rubber dam material over each tooth to be isolated, the assistant uses floss to slip the septum (rubber dam material between the holes)between the teeth without tearing the material. Always place the floss on the tooth, never directly on the rubber dam itself. Placement of the floss upon the tooth assists in bringing a single thickness of the dam through the interdental area
