Abstract
Lea SC, Felver B, Landini G, Walmsley AD. Three-dimensional analyses of ultrasonic scaler oscillations. J Clin Periodontol 2008; doi: 10.1111/j.1600-051X.2008.01339.x. Abstract Background: It is stated that the oscillation patterns of dental ultrasonic scalers are dependent upon whether the instrument is of a magnetostrictive or piezoelectric design. These patterns are then linked to differences in root surface debridement in vitro. Material and Methods: Piezoelectric (A, P) and magnetostrictive (Slimline, TFI-3) ultrasonic scalers (three of each) were evaluated, loaded (100 g/200 g) and unloaded with a 3D laser vibrometer. Loads were applied to the probe tips via teeth mounted in a load-measuring device. Results: Elliptical motion was demonstrated for all probes under loaded and unloaded conditions. Loading flattened the elliptical motion along the length of the probe. Unloaded, Slimline tip 1 was significantly different to tips 2 and 3 (p0.207). All TFI-3 tips were different to each other (p0.867). Generator power increased all Slimline and P tip vibrations (p
