Figure 1 Radiographic method for measuring crown height and root length in the assessment of the root/crown (R/C) ratio. a – apical level, i – incisal/occlusal reference line, RL – root length, Crh – crown height, m – the midpoint of the line connecting the mesial and distal proximal bone. Root length in mm=measured perpendicular from point m to point a. Crown height in mm=measured perpendicular from point m to i.
