Technical features to take into account for an ultrasonic scaler
As we already know, dental ultrasonic scaler are used in endodontics and periodontics for the removal of subgingival and supragingival plaque, the cleaning of tartar and surface stains, as well as in the surgical process. Years ago these procedures were performed manually with instruments such as curettes, sickles or chisels, which required much more effort for clinicians and stress for the patients, hence favouring a progressive switch to mechanical instruments. A) Handpiece The ultrasonic scaler handpiece is a fundamental element in an ultrasound device as it is essential that it is compatible with the tips we use. As we already know, these components work directly in the patient's mouth so it is important that they are self-cleaning at a temperature of 135 ยบ C for proper disinfection. Two other relevant aspects related to handpieces are their frequency and amplitude. For good cavitation, the frequency must be between 21-32 kHz. However, the frequency does not dir
