It is difficult to enlarge a root canal quickly using a hand reamer and file in a root canal stricture, a curved root canal or a molar tooth, so we experimented with mechanical equipment. We examined human extracted premolars which were preserved in physiological saline solution using a speculative root canal enlarging machine for ten, twenty or thirty seconds. After sectioning the tooth, we examined the enlarged root canal macroscopically and with an electronic microscope. Afterwards, we compared hand-instrumentation with the enlarging machine. As the result of this experiment : Observing the enlarging root canal, results obtained with the speculative machine (Type-2), were good at amplitude 2.0mm, low speed and 30seconds. This speculative apical file is useful in removing dentin splinters.
