Abstract

<p><b>Abstract : </b>A new technique using K files with modified tips has been developed for the penetration of constricted canals. The tip of a #10 K file was sliced diagonally to make it thinner. Since this modified K file has an especially fine tip and an appropriate stiffness, it followed constricted or sharply curved canals well and had a high penetration potential.</p><p> The author attempted to penetrate to the apical foramen in all 1884 canals of 977 teeth treated from 1987 to 1994. In 264 canals (14.3%) which could not be penetrated with conventional #10 K files, further attempts were made with the modified K files. As a result, the number of the non-penetrated canals was reduced to 75 (4.1%). There were 7 file breakages and 14 accidental perforations.</p>
