[Study of the influence of different instruments for removing dental deposits on tooth surface].

There are many contradiction literature data about different scaling and root planing instrument influence on hared dental tissues. We have tested dental enamel and cement surfaces after application of sonic, ultrasonic and hand instruments by scanning electron microscopy. The cement surface is damaged more, than a surface of enamel after scaling and root planing. The maximum damages have been produced by ultrasonic scaler surface and minimum - on hand scaler surface of the tooth. Ultrasonic scaler has removed root cement and bared dentinal tubules. Residual calculi have been found after sonic, ultrasonic, hand scaling. Scaling and root planing instrument influence on tooth enamel and cement needs further studies.
