A method of labelling tools, especially root canal files with a file member and a handle member, for facilitating identification of size and differentiating different sizes from each other, whereby the handles are labelled with two colours when the size differs from the sizes taken up in the ISO or ADA Standard and thereby stipulated colour, so that the handle has the stipulated colour for the closest underlying size as well as the stipulated colour for the closest above lying size, as well as root canal file labelled with the method and a kit comprising root canal files assorted according to size. |
