As we already know, ultrasonic devices 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.
