Fig. 6

a The position of the teeth, craniofacial and cervical spine regions in the LCR images. The coordinates of the upper left and lower right corners of each region are specified. The coordinate system is established with the upper left corner of the LCR images as the origin, the positive direction of the x axis to the right, and the positive direction of the y axis to the down. b, c, d are the quantified ARDA of each instance of the teeth, craniofacial, and cervical spine regions, respectively. In b, c, d the three surface plots from bottom to top are the cases in which the ageing-significant region threshold is set to the median, 75-th, and 90-th percentile of average ageing salience, respectively. Source data are provided as a Source Data file.
