Technique Tips for Ultrasonic Instrumentation

By Kathleen O. Hodges, RDH, MS

The usual method of accomplishing scaling and root planing in contemporary practice is with ultrasonic and hand instrumentation. Success with ultrasonic instrumentation relies on a relationship between an appropriate insert or tip for the task at hand, power setting for the type of deposits, use of the active tip area (ie, working end), and the working end to root angle. The power setting, which controls the length of the stroke or displacement amplitude, is generally discussed using the terms low, medium, and high.
