ABSTRACT:
A dental tool for facilitating gingival retraction.
A shank coupled to a handle terminates in a working end member having a curved edge shaped to generally conform to the curvature of the root surface of a tooth at the gingival level and also to the contour of the marginal gingiva. The exact shape of the curved edge varies with the type of tooth for which the tool is designed.
The tool can also be used for shielding the gingiva from a cutting tool working close to the gingiva, and as an aid in installing a rubber dental dam.
