Reciprocating Files is becoming more and more popular, however, it is more strict in student teaching.
Differ from rotary files, it is decreasing the operating sequence. It means, the most important reason is it can improve the working effiency but with the same safety.
We would like to introduce our RC gold and TF4 gold here.

1)Remove the bulk of the gutta-percha in the coronal third of the canal with an appropriate instrument, e.g. a Gates drill, or an ultrasonic instrument such as U Files. Depending on the consistency of the gutta-percha it is possible to start the retreatment directly with R25. 2) Use a drop of solvent as required. 3)Use R25 as described until working length has been reached. If resistance is encountered, do not apply pressure. Remove the instrument from the canal, re-apply solvent and try again.
