ABSTRACT:
The end of an instrument for the treatment of dental root-canals is coated with a layer of anti-friction material. The low coefficient of friction of the antifriction material and the fact that it renders the end of the instrument non cutting or non abrasive facilitates greatly the penetration of the instrument in the dental root-canal, especially when the canal is curved, and has the result that the instrument does not bite into the wall of the canal and does not exert thereon an action which is greater on the outside of the curve than on the inside thereof.
