Postcanine Enamel Thickness.

Units in mm. Means and where available standard deviations presented along with three measures:Average Thickness = Area of enamel cap÷Length of enamel dentine junction.Relative Thickness 1 = (√Area of enamel cap÷Length of enamel dentine junction)×100.Relative Thickness 2 = (Average Thickness÷√Area of the dentine)×100.单位：毫米（mm）。本数据集给出均值及可提供的标准差，同时包含三项计算指标： 1. 平均厚度 = 牙釉质帽（enamel cap）面积 ÷ 釉牙本质界（enamel-dentine junction）长度； 2. 相对厚度1 = (√牙釉质帽面积 ÷ 釉牙本质界长度) × 100； 3. 相对厚度2 = (平均厚度 ÷ √牙本质（dentine）面积) × 100。
