||Vibration of dental handpieces
||July-Aug. 2001, Vol.62, No.4, p.477-481. Illus. 10 ref.
||The vibration of new and used dental hand pieces was tested in three directions during idling. Work was simulated by drilling on plastic plate. An analysis was performed of the weighted vibration and the total acceleration of high-frequency vibration ("ultra vibration"). Neither the water and air injection nor the grip force of fingers had any significant effect on the vibration level. The weighted accelerations were well below hazardous levels. The vibration spectra of the hand pieces contained powerful vibration at high frequencies, but the effects of this ultra vibration and exposure during work are not well known.
