From: Gingival shape analysis using surface curvature estimation of the intraoral scans
Mean and standard deviation of gingival shape parameter (GS) (i.e., the 95th percentile of the curvature values)—light grey, and method error, i.e., the absolute difference in the GS between scan and rescan—dark grey, obtained for each diameter and curvature measure for a study sample represented with bar charts. The central and interdental region sample size was 78 and 88, respectively
