ABSTRACT:
This application relates to the field of Dentistry, and in more particular to the use of root canal excavating implements such as files, broaches, reamers, or probes employed for the use of clearing tissue and removing dentin from the nerve canal of teeth. An introduced bent tip of 45 degrees to the angle of the implement, at a distance as close as a half of one millimeter from the leading tip, is cited as an improved means to get the tip of the implement to the desired working length.
