title: [Needles in dental practice. Clinical evaluation and experiments on deformation and siliconization].
abstract: The authors have considered: a) the rate of the deformation of three different needles (Groups B, V, R) when used in different clinical conditions; b) the modification of the surface silicon of the needles after in vivo and in vitro stress. The results have shown a good behaviour of all the groups when employed through the mucous membrane, but a progressively increased deformation after contacts with an osseous surface, significantly higher for groups B and V than group R. No difference in the surface silicon, both among the groups and in relation to the technique of utilization.
