Top ROW: The teeth images (A) and (B) are used to illustrate 2-dimensional segmentations similar to the radiographs (C) and (D). From the top left, in image (A) illustrates the location of the CEJ on the tooth. The portion of the tooth identified as above or coronal to the dotted line is defined as the coronal portion of the tooth, and the area of the tooth below or apical to the CEJ is considered the root portion of the tooth. Image (B) depicts in 2 dimensions how the tooth is segmented to calculate DMFP by identifying the coronal portion of the tooth that is decayed (red), missing (orange), and filled (green). Image (C) shows a standard periapical radiograph without AI generated predictions. Image (D) shows the AI-analyzed image illustrating the decayed, missing and filled segmentations on this radiograph. The DMFP calculation for tooth number 30 is 0.71. Bottom Row: Image (E) illustrates the anatomical landmarks that are used to measure the interproximal alveolar bone level: CEJ and crest of bone. The distance between these two points is the reported bone level (BL). This measurement is analyzed on the mesial and distal of each tooth on the radiograph and can be seen on the bone level image (F).
