Abstract
A dental space and periodontal cavity measuring instrument for insertion in interdental or interproximal spaces between teeth and in periodontal cavities in both the upper and lower dental arches to determine the width of such spaces and the depth of the cavities, respectively, for appropriate treatment. The dental space and periodontal cavity measuring instrument is characterized by a centrally located handle provided with a pair of oppositely-extending single tips or multiple, elongated, graduated cylinders which terminate in graduated ends, for insertion in the interdental spaces and periodontal cavities. The calibrated cylinders and graduated ends may be extended in a straight line from the handle, or one or more cylinders in one or both of the calibrated and graduated tips may be angulated and the diameter of each cylinder may be indicated on the handle for size-identification purposes. The ends of the cylinder or stem tips may also be 'waffled' with striations for ligature tucking purposes.
