Abstract

PROBLEM TO BE SOLVED: To dispense with an auxiliary tool and reduce an error in measurement accuracy and a bacterial infection pathway in root canal treatment by providing a bar-like body and a scale for measuring the length of a blade part inserted in the pulp root canal of a tooth on the cutting blade. SOLUTION: A reamer file has a handle part 1 and a blade part, and the blade part is formed by a bar-like body with a scale 8 and a cutting blade 3. In this case, the reamer file is inserted in the pulp root canal 7 of a tooth 9. The scale 8 visually confirmed from the outside of the pulp root canal 7 is read to measure the insert length into the pulp root canal 7. In measurement, direct measurement can be made to reduce the probability of bacterial infection due to contact and decrease a measurement error.

た。In the conventional reamer file, the insertion length of the blade 2 into the root canal 7 of the tooth 9 is determined by using the rubber stop 5 as shown in FIG. The length from the tip to the rubber stop 5 is measured using the measure 6. However, there has been a problem that a measurement accuracy error is likely to occur, and the possibility that the number of bacterial infection routes due to contact increases due to an auxiliary device such as a measure.
