Find different H values for the different distances of teeth from the root of the teeth. Plot the graph between H vs Distance from the root. From the graph find the Hmean.

Three values of H found at three equidistance points (i.e. two ends and at the middle along with the height of the tooth).

H m e a n = H 1 + 4 H 2 + H 3 6

H m e a n = H 1 3 (H at 1/3 hight of the tooth from narrow end.

All of these
