Giải thích
Dental unit water used for nonsurgical procedures should contain no more than 500 CFU/mL of heterotrophic bacteria, the same standard applied to safe drinking water. Counts of 5,000 or 50,000 CFU/mL indicate biofilm growth in the waterlines and require treatment of the system. Sterile solutions delivered through a sterile device are used for surgical procedures instead.
