Root feature
The root feature of the tooth is a distinguishing feature for determining whether a tooth belongs to the right or left half of the jaw .
The root feature refers to the angle between the direction of the tooth root and the tooth axis.
The root generally deviates distally from the crown .
The root feature can be used to determine whether a tooth comes from the right or left half of the jaw (see forensic medicine ). The root feature is often reinforced by an additional curvature of the root tip, also distally.
The distal curvature of the root tip is attributed to the growth pressure of the additional teeth (7th, 8th) that will later erupt.
Further identification features for the side membership of a tooth are:
The crown alignment is also used to assign posterior teeth to the upper or lower jaw .
