Abstract
A dental instrument comprising a metal shaft having a resilient extension at one end and a further functionally closely related instrument such as a periodontal probe or mirror at the other end. The resilient extension has two deformable surfaces which can be pressed against a tooth to test its mobility. The periodontal probe is color-coded, so that the depth to which the projection has been inserted into the gingival sulcus and any existing periodontal pocket is readily apparent to the dentist. The dental instrument can include a percussive hammer adjacent the resilient section.
Claims10
A dental instrument comprising a metal shaft having an extension at one end thereof including a resilient, deformable surface thereon adapted to be pressed against a tooth to test the mobility of said tooth, and a periodontal probe at the other end of the metal shaft which includes a color-coded depth gauge.
A dental instrument comprising a metal shaft having an extension at one end thereof including a resilient, deformable surface thereon adapted to be pressed against a tooth to test the mobility of said tooth and wherein the resilient, deformable surface is serrated.
A dental instrument comprising a metal shaft having an extension at one end thereof including a resilient, deformable surface thereon adapted to be pressed against a tooth to test the mobility of said tooth and wherein the resilient, deformable surface has a pair of sections, the second section thereof inclined approximately 45.degree. from the first section whereby mobility of teeth in different locations can be readily tested.
A dental instrument comprising a metal stem having a sharply pointed projection at one end forming a periodontal probe, said projection divided into transverse color-coded sections, whereby the depth to which the projection has been inserted in periodontal tissue is readily apparent, and wherein the color-coded sections are progessively coded from the tip in shades of green, yellow and red to provide a traditional progressive warning indicator.
A dental instrument comprising a metal shaft having an extension at one end thereof including a resilient, deformable surface thereon adapted to be pressed against a tooth to test the mobility of said tooth, a transverse projection on the metal shaft adjacent to said extension and adapted to be used as a percussive hammer, and a periodontal probe at the other end of the metal shaft having a color-coded depth gauge so that the depth to which the projection has been inserted in periodontal tissue is readily apparent.
