Abstract

Certain health problems may appear both in dentists and dental technicians due to long periods of exposure to vibrations.
The aim of the study was to measure and compare some factors related to vibrations which affect the health of dentists and dental techicians, particularly those produced by mocromotors with drills of different shapes, made of different materials rotating at different speeds.
Vibrations were measured by an accelerometre which was placed an the technical micromotor and on various body parts of subjects. The device consists of a piezosensor, an amplifier, a filter and mobile recording device. The obtained signals were analysed by the SpectraLAB computer programme and consequently compared with presently valid international standards. Statistical data analysis was carried out by PC software, STATISTICA for Windows, Release 5.5 H and SPSS for Windows, Release 7.5.
The main factor that effects vibration is the rotation number used in the course of prosthetic replacement processing.
The obtained results point to the fact that the vibration acceleration values are within accepted standards, although the vibration values at 40000 rotations per minute approach the maximum limit of these standards. The spactral analysis of vibration revealed that the rotation number determined the frequencies of the maximum values. Since there is strong evidence to support vibration related illnes in dentists and dental technicians, it is recommended that individuals who use such devices be warned about the possible harmful effects. The obtained results may be used in prevention of such illness. They are also recommended to use rotation speeds which produce the least vibrations.
