ABSTRACT:
A dental root marking and measuring instrument used for determining the position of the apex of a dental root and measuring the thickness of the alveolar bone facing the lip comprising a main body having a mounting portion, a reamer on the mounting portion with an end which may reach the apex of a dental root, an arm disposed alongside of the reamer having a base end rotatably supported on the main body and a free end rotatable toward the reamer, a positioning member on the lower portion of the arm for adjusting the distance between the main body and the arm, and an indicating pin connected to the upper portion of the arm for putting a mark on the gum having a free end alignable with the free end of the reamer. The free end of the indicating pin is aligned with that of the reamer, and the reamer is inserted into the pulp canal of a tooth so that its end may be disposed at the apex of its root. The free end of the indicating pin is pressed into contact with the gum to mark it, and the positioning member is moved so that its end facing the main body abuts the mounting portion to define a fixed distance between the arm and the main body. The arm is turned outwardly, the reamer is drawn out of the pulp canal, and the entire instrument is removed from the mouth.
