The first number in a dental or medical instrument formula indicates the width of the blade or working tip in tenths of a millimeter (0.1 mm). For example, a formula starting with "10" means the blade is 1.0 mm wide. The second number typically indicates the length of the blade in millimeters, and the third number indicates the angle of the blade in degrees.

The expansion of the marrow space due to increased hematopoiesis can lead to resorption of the outer cortical bone and the formation of new bone, resulting in the characteristic "crew cut" appearance on X-rays. This appearance is due to the trabecular pattern of the skull becoming more prominent as the outer layer is resorbed.

In a patient with a suspected STEMI, the characteristic ECG findings include ST elevation in the anterolateral leads (I, aVL, V1-V6) and reciprocal ST depression in the inferior leads (II, III, aVF). The pattern of ST elevation in the anterolateral leads with reciprocal depression in the inferior leads is most indicative of a STEMI affecting the anterolateral wall of the heart.
