Improvement of the rubber dam frame

An improvement of the rubber dam frame for obtaining the endodontic operative field is proposed. The device consists of an articulated frame that maintains the currently used standard rubber dam sheet in position. A hinge allows the frame to be folded, resulting in easier accessibility to the working area. This accessibility facilitates taking of radiographs, administration of additional doses of anesthetics, and evacuation of therapeutic liquids, which may have accidentally entered the buccal cavity. In addition, a reservoir at the bottom of the frame allows the placement of gauze compresses and an aspiration cannula to avoid leakage of fluids such as sodium hypochloride onto the patient's clothing.
