1.Id, specimen number; δ/δsd, mean/standard deviation of occlusal enamel thickness; δst standard occlusal minimum enamel thickness; Γ, occlusal relief index of OES (first column) and EDJ (second column); ψc, number of patch for OES (first column) and EDJ (second column); φbi, blunting index; φp, relative crest area for OES (first column) and EDJ; φmci, maximum convexity index for OES (first column) and EDJ.
