ABSTRACT:
An improved dental treatment tool includes a rotation shaft with an eccentric rotation plate having a drive pin thereon, and a vertically moving rotation cylinder for allowing a dental drill to move in vertical and horizontal directions. The rotation plate and the drive pin are engaged respectively with two portions of the vertically moving rotation cylinder so that the vertically moving rotation cylinder is automatically caused to rotate horizontally and move up and down, to thereby provide an excellent dental treating operation.
