#35 K-file at D16?
A- 0.35
B- 0.41
C- 0.67
D- 0.74
ANS:C
A file has two designated points called D0 and D16. D0 is the starting point of the file and D16 is the point
where the cutting/abrasive part or in other words the flutes/blades end. Distance between these two points
is fixed at 16 mm. Doesn’t matter however long the file is, the distance between D0 and D16 is always 16 mm.
Now, the diameter at D0 is hundredth part of the size of file. So here file #35 would have diameter at D0 as
0.35 mm. If not specifically mentioned the general taper of the file is 0.02mm per mm. So as you move
upwards to D16 from D0, each mm adds 0.02 mm in diameter.
Total 16 mm adds 0.2 * 16= 0.32mm and the diameter at D0 was already 0.35mm so at D16 would be 0.35 +
0.32 = 0.67 mm.
