 note = {P(論文), Because root canal preparation in root canal treatment takes long time, various special contraangle handpiece are developed to promote efficiency of root canal preparation. Root canal are prepared with computerized micro motor handpiece. The purpose of this study is to examine the time of root canal preparation and the difference of sealing efficiency of root canal fillings between exclusive point and other point after preparation in the cases of files Endo and motor technika vision, and to find their advantage and problem. The results obtained in the case of root canal preparation with Endo motor tecnika were as follows. 1. Time of root canal preparation was shorter than in the case of hand files. 2. Time of the preparation was almost the same irrespective of the difference in the root canal curve. 3. The tip of files tends to deviate from the root apex for root canals with great curvature. 4. Sealing efficiency was maintained without exclusive point. It is suggested that the pressure in preparation should also be taken into account and that the necessity of practices using teeth models should be taken into account.},
