Measurement of mandibular cortical width (MCW) on panoramic radiograph. A line was drawn connecting the apices from premolar to premolar, from which a perpendicular was dropped to the external cortex of the mandible. A line tangent to the outer cortex was then drawn, to which a perpendicular was drawn and the MCW was measured bilaterally using a digitometer from the corticomedullary junction to the external cortex.
