A step-by-step guide to the method. (A) Le Moustier 1 LRC epoxy replica with the cusp toward the right of the image (scale = 3 mm). An LEH defect is marked by an arrow. (B) An overview image within the SensoSCAN software (S Neox, https://www.sensofar.com/metrology/products/sneox/) with a bounding box marking the crown region to be scanned. (C) The resulting digital elevation model (DEM), showing the defect as a reduction in enamel thickness. (D) The DEM is read into ImageJ software47,48 where a transect is drawn from one occlusal shoulder to the other to extract 2D coordinates for analysis. (E) Once plotted, the FindPeaks plug-in49 is used to measure maximum defect depth from the occlusal side of the defect (in µm).
