![]() To collate the research reported on the various hazards associated with the ultrasonic dental scaler and discuss possible future research areas. These include heating of the tooth during scaling, vibrational hazards causing cell disruption, possible platelet damage by cavitation, associated electromagnetic fields that can interrupt pacemakers, auditory damage to patient and clinician and the release of aerosols containing dangerous bacteria. The ultrasonic dental scaler is a valuable tool in the prevention of periodontal disease however, this equipment has a number of hazards with which it is associated. Ultrasonic dental scaler: associated hazards. Loaded probes oscillated with an elliptical pattern. Probe oscillation patterns are independent of ultrasound production mechanism and are dependent upon probe shape and generator power. ![]() Generator power increased all Slimline and P tip vibrations (p<0.0001). All TFI-3 tips were different to each other (p0.867). Unloaded, Slimline tip 1 was significantly different to tips 2 and 3 (p0.207). Loading flattened the elliptical motion along the length of the probe. Elliptical motion was demonstrated for all probes under loaded and unloaded conditions. Loads were applied to the probe tips via teeth mounted in a load-measuring device. 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. These patterns are then linked to differences in root surface debridement in vitro. ![]() It is stated that the oscillation patterns of dental ultrasonic scalers are dependent upon whether the instrument is of a magnetostrictive or piezoelectric design. Lea, Simon C Felver, Bernhard Landini, Gabriel Walmsley, A Damien Three-dimensional analyses of ultrasonic scaler oscillations. An ultrasonic scaler is a device intended for use during dental cleaning and periodontal (gum) therapy to remove calculus deposits from teeth by application of an ultrasonic vibrating scaler tip to the teeth.
