Abstract: A training system includes a tool connected to a control module. The tool includes a tip and a grip having two or more force sensing transducers configured to enable determination of sensor force measurement data. The control module receives the sensor force measurement data. The control module includes a storage device configured to store zeroed force data, and a data processing unit including a processor and memory storing instructions that, when executed by the processor, cause the processor to obtain the sensor force measurement data and the zeroed force data; determine, based upon the sensor force measurement data and the zeroed force data, a load force magnitude that is independent of grasp forces; determine whether the load force is within a set range; and, provide a corresponding indication where the load force is within the set range and/or where the load force is outside of the set range.

Abstract: A dental ultrasonic tool configured to connect to a magnetostrictive or piezoelectric transducer of a dental instrument operating in the frequency range between 18 kHz and 50 kHz. The tool includes a tip and a singular surface marking having a minimum width of 0.5 mm disposed on the tip. The tip includes a distal point as a datum. The singular surface marking is spaced-apart from the distal point of the tip and defines at least one edge. The at least one edge is not coincident with a first flexural node of the tip at an operating frequency of the tip. Dental ultrasonic tip wear measurement tools for measuring the wear on a tip are also provided.
