Conservative and Endodontics MCQ Answer 8

Wednesday, June 21, 2000

Answer is c.


The file number represents the size at D0 which is the tip of the file. The number 10 file is 0.10mm in diameter at D0, and tapers at 0.020mm for 16mm and terminates at a diameter of 0.42mm at D16 which it the end of the flutes at the shank. ISO file sizes 10 through 60 have diameters at D0 that increase by 0.05mm. From No. 60 onward to 140 D0 increases by 0.10mm. How about the No. 6 and 8 file you ask, well just think of them as in hundredths of a millimeter in that a No. 6 file is 0.06mm and No. 8 file is 0.08mm at D0. (Pathways of the Pulp 8th, p250)
