Sterilization pouches make sure that dental instruments and other tools are stored in a sterile environment. These pouches keep contaminants and infections from spreading during handling and storage. After being washed, instruments must be placed in the pouches to ensure that they remain clean until their next use. No patient wants dusty tools to be placed in their mouth. To use, fold the perforation back and crease with the protective strip still in place. Fold back into place. Using clean gloves and other personal protective equipment, load the cleaned instruments into the pouch. Make sure they are dry, and ensure that the bag is not overfilled.
