An analysis of the literature on the aggressiveness of magnetostrictive and piezoelectric ultrasonic scaling devices on tooth substances showed varying results. Tooth surface alterations produced using hand or ultrasonic instruments are of particular concern during periodontal therapy. Piezoelectric units operate in the 25 kHz to 50 kHz range and are reactivated by dimensional changes in the crystals housed within the hand-piece as electricity passes over the surface of the crystals tip movement is primarily linear in direction. Magnetostrictive units operate between 18 kHz and 45 kHz using flat metal strips in a stack or a metal rod attached to a scaling tip, and the tip movement is elliptical. Ultrasonic units in dentistry are currently available in two basic types: magnetostrictive and piezoelectric. Ultrasound can be produced by magnetostriction or piezoelectricity. Ultrasonic instrumentation is as effective as hand scaling for plaque and calculus removal and the successful healing of diseased periodontal tissues. Ultrasonic and sonic scalers differ in their efficiency in removing calculus from tooth surfaces. Ultrasonic and sonic scalers are referred to as power-driven scalers. Currently, hand instruments and sonic and ultrasonic scalers are used most frequently. The techniques used for scaling, root planning, and curettage are hand instrumentation, sonic and ultrasonic instrumentation, laser scaling, demineralization, and chemical scaling. This goal can be achieved by eliminating supra- and subgingival plaque and establishing destructive conditions because the essential characteristic in the treatment of periodontal diseases is the mechanical removal of bacterial deposits and calculus. Periodontal therapy aims at arresting periodontal infections and maintaining a healthy periodontium.
