Measuring Crown Height (CH) *Measure crown height in mm

Measuring Crown Height 1. The first step is to turn the tooth into a triangle by marking three points on a sheet of paper: A) where the crown meets the left root lobe, B) where the crown meets the right root lobe, and C) the tip of the crown (see image below). 2. Now measure a perpendicular line from the crown tip (C) to the line segment AB. This is your crown height, or X in your equation. Remember to measure the CH in millimeters.
