Classification of the position and relationship of the IAN canal with the right mandibular third molars using the cylindrical coordinate system. This approach can be defined as follows: (1) Use the IAN bundle as the original reference point (point O); (2) find the point on the third molar (point P) closest to the IAN bundle, and draw a line (line OR) from the original reference point (point O) to point P; and (3) determine the angle between the inferior-superior axis (line OQ) and line OR
