From: Gingival shape analysis using surface curvature estimation of the intraoral scans
Two regions of interest (ROI), i.e., central and interdental, are displayed on a gingival margin band to facilitate focused visualisation. Corresponding histograms and boxplots are shown to display the distribution and variability of the curvature values. Local maximum values (red) are of interest for gingival shape analysis. Whiskers represent 5th and 95th percentile values, and + represents mean value
