From: RANKL deletion in periodontal ligament and bone lining cells blocks orthodontic tooth movement
Orthodontic tooth movement and PDL width measurements. a Orthodontic tooth movement was quantified by measuring the minimum distance between the maxillary first and second molar crowns. Bar = 1 mm. b The average PDL width was quantified by measuring the mean PDL space on the distal aspect of distobuccal root in sagittal micro-CT images. c The mid-root PDL width was measured on the distal aspect of the distobuccal root in horizontal micro-CT images 400 μm apical to the furcation as shown in b. MB, mesiobuccal root; DB, distobuccal root; PDL, periodontal ligament
