Dental Multi-Purpose Slowspeed Handpieces Test and Evaluation

摘要

This study included the test and evaluation of three air-driven operative, three electrical operative, two air-driven surgical, and three electrical surgical handpieces. Speed and torque of the handpieces were compared by the use of a hysteresis electric dynamometer. Comparisons were also made of handpiece characteristics. User evaluations were performed in U.S. Air Force dental clinics, and results are presented. The purpose of the study was to provide assistance to the base dental surgeons for selection of dental multi-purpose slowspeed handpieces.
