In 1957, DENTSPLY pioneered ultrasonic scaling with the introduction of the first standalone dental ultrasonic scaler. The unit operated at 25K, was manually tuned and operated using 3 electronic vacuum tubes. The ability of the ultrasonic scaler to use water to cool the tip and provide lavage combined with ultrasonic energy to fracture and remove hard and soft deposits of plaque and calculus made routine scaling of teeth much more efficient for clinicians At this point in time, the ultrasonic scaler was reserved only for the removal of heavy supragingival calculus. This was due to concerns of potential root surface damage and the focus of periodontal therapy on scaling and root planning to achieve root surfaces free of calculus deposit and planed to the smoothness of glass. Much has changed since 1957. Today ultrasonic instrumentation is a well-established and evidence based method for deposit removal. Ultrasonic instrumentation greatly enhances the ability of dental care providers to maximize patient therapy outcomes. For over 50 years, Cavitron® Systems have been a mainstay in the dental office. Since then, DENTSPLY Professional has continued to make improvements based on the most current research and the needs of clinicians and patients.
