Abstract
Dentists use hand-held instruments such as shepherd's hooks, periodontal probes, and spoon extractors to detect, diagnose, and treat dental disease. Although several probes facilitate the application of a single repeatable force or pressure (especially important in periodontal probing), none of them measure the range of forces applied during a clinical procedure, the reproducibility of these forces, or changes in force profile. Obtaining real time data on the profile of the forces applied (e.g., peak magnitudes, frequency, duty cycle, etc.) would be useful in clinical research, clinical instruction, and classroom instruction. This study presents the development of a handheld force measuring sheath for use with standard dental instruments. During a clinical exam, the sheath measures the forces exerted by a dentist on the dental instrument. Strain gauges in the sheath measure these forces in three orthogonal directions. Analog and digital circuitry condition and display the signal for forces ranging from -250 to 250 g in all three directions. This prototype force measuring sheath will allow the establishment of a force database for interactive haptic simulations, comparison between clinical performances, and the measurement of the material properties of dental structures.
