![]() Both have been clearly proven to be effective for calculus and stain removal. The piezoelectric ultrasonic scaler was more efficient than the magnetostrictive ultrasonic scaler in removing calculus but left the instrumented tooth surface rougher. Magnetostrictive (available from Dentsply and Parkell) and piezoelectric (available from EMS and Hu-Friedy) power scalers are the two types of ultrasonic devices seen in dental hygiene practice. There are two main types: magnetorestrictive and piezoelectric. The objective of these non-surgical procedures is to remove etiologic agents such as dental plaque and tartar, or calculus, which cause gingival inflammation. The SEM examination revealed the smoothest surfaces but, subjectively, the most tooth substance loss after the curette, followed by the magnetostrictive instrument, with the least substance loss, and then the piezoelectric instrument, with medium substance loss. The most common type of mechanical scaler in veterinary dentistry today is the ultrasonic scaler. The end Ra values were significantly worse for the piezoelectric instrument (2.02+/-0.41 p<0.05) compared to 1.42+/-0.48 for the curette and 1.36+/-0.41 for the magnetostrictive instrument. Remaining calculus was similar for all three groups. The results revealed that the time needed for instrumentation was 126.1+/-38.2 s for the curette, significantly more than for the piezoelectric ultrasonic instrument (74.1+/-27.6 s p<0.05) and 104.9+/-25.4 s for the magnetostrictive ultrasonic instrument.
