Your first weeks in the dental office
This primer explains the dental office in plain words: the tools on the tray and how to tell them apart, the machines in the operatory and the sterilization room, the liquids and chemicals you will handle, and the steps that make an instrument safe to use again. It is written for dental assistants, including anyone who also helps in sterilization. Any technical word links to a plain-English definition.
Every fact is sourced. Always follow your office's written protocols, the manufacturer's instructions and your state's rules; this page explains them, it doesn't replace them.
