ABSTRACT:
A dental file is disclosed which is particularly useful in endodontia for removing dead or damaged tissue from a curved tooth root canal. The file has a flexible tapered shank which has a cutting surface on its periphery and a pilot projecting from the tapered end of the file for guiding the shank along the curved root canal preventing the cutting surface near the end of the shank from gouging into the wall of the curved root canal or penetrating too far through the apical foramen of the root canal.
