Rubber dam isolation is an essential method for limiting contamination in the dental operative field. Different materials and models of rubber sheet, clamps, frame and accessories are available to fit specific dental configurations. The preparation and installation of the isolation dam is subject to different methods based on the situation and the expertise of the operator. A range of variations in the isolation field and alternative manipulations are offered to dentists to adapt to different cases. Maintaining proper protocols reduces aerosol contamination and the risk of dental materials spreading loose in the oral cavity, leading to improved results and patient satisfaction.
