Irrigation to clean and disinfect a canal is an important part of a root canal, and the different endodontic irrigation instruments accomplish this task in different ways. These instruments and systems are used following the shaping of the canals and prior to obturation. While different instruments irrigate in different ways, they are all designed to safely and efficiently deliver a cleaning solution throughout the canal. Some irrigation instruments are syringes with very small and flexible tips, while others are automated and employ negative pressure to make the irrigation process easier and more effective. Whatever style of irrigation instrument you select, be sure you are comfortable with how it is used prior to using it with a patient.
