ABSTRACT:
The pulp canal of a tooth requiring filling is hollowed out using boring bits fitted to and driven by a vibrating instrument; the bits are organized in sets, with a number of discrete sets making up the full range. The abrasive tine of the bits of each set is tapered; its length and tip diameter remain the same throughout the set, whereas the diameter at the point where it joins with the shank increases progressively from the smallest to the largest size.
