Note: A1B1 represents the length from the root DE represents furcation position to the apical position; C1D1 represents the length from the start point to the end point of the furcation groove; A1C1 represents the length from the root furcation position to the start point of the furcation groove; B1D1 represents the length from the apical position to the end point of the furcation groove; furcation groove depth of different levels.
