To reduce the risk of disease transmission in the dental office, it is recommended to

reuse instruments when possible
use disposable items whenever possible
disinfect all items regardless of use
limit patient contact

The correct answer is: use disposable items whenever possible

Using disposable items whenever possible is recommended because it reduces the risk of disease transmission in the dental office. Reusing instruments when possible (option A) can lead to cross-contamination and increase the risk of disease transmission. Disinfecting all items regardless of use (option C) is important, but using disposable items further reduces the risk. Limiting patient contact (option D) may help in reducing transmission, but it is not the most effective method compared to using disposable items.
