![]() This study revealed that applying a piezoelectric scaler with 200 g of lateral force leaves smoother surfaces than a magnetostrictive device with the same lateral force.ĭental calculus Dental scaling Tooth extraction. For root surface roughness, we only found a statistically significantly poorer result for the C200 group in comparison to the P200 group (P=0.033). The mean time needed for instrumentation for the piezoelectric and magnetostrictive devices was 50:54 and 41:10, respectively, but their difference was not statistically significant (P=0.171). he teeth were scaled and the data on the duration of scaling and the amount of surface were collected and analyzed using the t-test. A reinforced aluminum chassis provides a very durable and reliable unit. To compare, only the lateral sides of piezoelectric technology are active. Conversely, piezoelectric devices have a linear movement of the tip, no magnetic field, and only the lateral surfaces of the tip are most active.9. The lateral sides are most commonly used, but the face and back are also active. Ultrasound can be produced by magnetostriction or piezoelectricity. ![]() This combination produces a powerful and potent tool against periodontal disease. Additionally, magnetostrictive scalers have an elliptical or circular tip movement with all surfaces of the tip being active. Ultrasonic instrumentation is as effective as hand scaling for plaque and calculus removal and the successful healing of diseased periodontal tissues 5, 6. The design of the Engler Piezo scaler circuitry uses integrated computer technology along with our Time Remote Feedback Circuitry. In the other two groups (P100 and P200), the teeth were scaled with a piezoelectric device with 100 g and 200 g of lateral force, respectively. Thank you for purchasing the Engler Piezo Scaler. In two groups (C100 and C200), the teeth were scaled using a magnetostrictive device and two different lateral forces: 100 g and 200 g, respectively. This study aimed to compare the results of scaling using magnetostrictive and piezoelectric devices on extracted teeth.įorty-four human extracted teeth were assigned to four study groups (n=11). Initially they were used to cut teeth but very quickly they became established as an ultrasonic scaler which was used to remove. The effects of magnetostrictive and piezoelectric devices on tooth surfaces seem to differ with regard to the root surface roughness they produce. Ultrasonic instruments have been used in dentistry since the 1950s.
