544 The Science -How Ultrasonics Actually Work: Amplitude, Frequency, and Cleaning Efficiency

In this episode of A Tale of Two Hygienists, Jessica and Dave welcome back Noel and Richard Paschke, better known as Mr. and Mrs. Ultrasonics. Together, they break down the science behind ultrasonic instrumentation, separating fact from fiction on topics like frequency, amplitude, cavitation, cleaning efficiency, and clinical technique. Rich shares an engineer's perspective on how ultrasonic devices are designed, while Noel translates the physics into practical applications for today's clinician. They also discuss common misconceptions about piezo and magnetostrictive units, how worn tips impact performance, and why understanding ultrasonic technology is essential for delivering better patient care. In this episode, you'll learn: The difference between frequency, amplitude, and cleaning efficiency Why ultrasonic scaling is about more than simply turning up the power Common myths surrounding cavitation and calculus removal Key differences between piezo and magnetostrictive systems How tip design, wear, and adaptation affect clinical outcomes The latest innovations from the Paschkes, including cordless ultrasonics and a patent-pending piezo swivel handpiece.
