Supporting controlled endodontic workflows

During root canal preparation, the clinician selects the file, working parameters and irrigation sequence according to the case and file system. Adjustable speed and torque can help match the motor’s operation to the selected instrumentation protocol. The DM-1’s measurement-related alert provides additional feedback, but it does not replace established clinical length-determination methods or radiographic assessment where indicated. Before treatment, check file seating and ensure that the battery is charged. Clean and maintain the instrument as directed by VRN, and verify the charging components and supplied accessories against the product packaging.
