摘要

The root canal file has integrated channel inlet dental drill for the simplification of the channel Instrumentation. A conical dental drill with handle for manual instrument (1) is attached at a shaft (2) of the root canal file. The conical dental drill is large enough to extend around the channel input so that the introduction of the file force is simplified. The dental drill portion is wide enough to allow a clear and conical expansion of the root canal input. A working portion (4) of the root canal file is approximately 10-15 millimeter long.
