In an instrument formula, what does the second number represent?

Width of the blade in tenth of millimeters
Angle the cutting edge makes with the handle in degrees
Length of the blade in millimeters
Angle the entire blade makes with the handle in degrees

The correct answer is: Angle the cutting edge makes with the handle in degrees

In an instrument formula, the second number represents the angle the cutting edge makes with the handle in degrees. This is an important parameter to consider when selecting the appropriate instrument for a specific dental procedure. The angle of the cutting edge can affect the access and effectiveness of the instrument during use. Therefore, understanding and paying attention to this angle in instrument formulas is crucial for successful clinical outcomes. Regarding the other options: A. Width of the blade in tenth of millimeters: This is not the second number typically represented in an instrument formula. C. Length of the blade in millimeters: While the length of the blade can be an important factor in instrument selection, it is not what the second number in an instrument formula typically represents. D. Angle the entire blade makes with the handle in degrees: This option describes a different angle that is not commonly specified in instrument formulas.
