[Influence of noise and vibrations on teeth abrasion]

The purpose of the investigation was to determine the influence of noise and vibrations on teeth abrasion in textile workers. For testing purposes a random sample of 115 workers who were exposed to 99-105 decibels of noise, was selected. After thorough investigations it was found that noise was a detrimental stress--producing factor causing quite a number of diseases. Noise can be a stress-producing factor causing parafunctions. The parafunctions are a major aetiological factor that causes teeth abrasion. These investigations proved the correlation between the duration of noise and exposure to vibrations and patological abrasion of hard teeth tissues. The teeth abrasion was more frequent in textile workers who were long exposed to high level of noise.
