instrument, formula name of,
n a method of naming and describing dental hand instruments. Measurements are in the metric system. The working point is described first; then the formula is given, in three (or sometimes four) units. The first figure denotes the width of the blade, in tenths of millimeters; the second shows the length of the blade, in millimeters; and the third indicates the angle of the blade in relation to the shaft, in centigrades or hundredths of a circle. Whenever it is necessary to describe the angle of the cutting edge of a blade with its shaft, the number is entered in brackets as the second number of the formula. Paired instruments are also designated as right or left. In lateral cutting instruments the one used to cut from right to left is termed
right; in direct cutting instruments with right and left bevels, the one having the bevel on the right side of the blade as it is held with the cutting edge down and pointing away from the observer is termed
right.
