A color coded elastomeric ring is fit onto a dental instrument. The elastomeric ring includes axial and circumferential formations for increased traction of a dental practitioner's finger to manipulate the instrument. Advantageously, two elastomeric rings are provided, one at each end of the instrument. Each elastomeric ring preferably has an outside profile with a decreasing diameter toward the adjacent end of the instrument. The ring is located adjacent to a receiving port for a tool insert or point.
