In modern dentistry, Rubber Dam is a must in every dental surgery. Its routine use will greatly contribute to success in many dental treatments. Rubber Dam takes a few minutes to apply but the benefits easily compensate. Rubber Dam is essential for complete moisture control, will improve visibility and protect the buccal, labial and lingual areas in the oral cavity. Increased visibility and protection enable the procedure to be carried out effectively and efficiently. For optimum performance and to avoid reduced strength from perishing, Rubber Dam material should be kept in a closed box or tin and preferably refrigerated.
