In a dental instrument with a formula of 10-85-8-14, what does the number 10 refer to?

Width of blade in tenths of a millimeter
Length of blade in millimeters
Primary cutting edge angle
Blade angle

The correct answer is: Width of blade in tenths of a millimeter

The number 10 in this formula refers to the width of the blade in tenths of a millimeter. This means that the blade is 1 millimeter wide, making it a fairly narrow blade. The other options are incorrect because they do not match the format of the formula. Option B refers to the length of the blade in millimeters, which is not indicated by this formula. Option C and D refer to angles, while this formula solely contains numerical measurements.
