Variations in the depth of scratches in a transverse section of a premolar was studied. The scratches were produced by a Vickers diamond whose vertical deviations during scratching were measured by an inductive distance recorder and continually registered by an xy-recorder. The depth of scratches in all areas of the enamel was almost constant with only minimal variation. In the dentine, too, the variations were small, the constant being greater than in the enamel. The greatest depth was measured in interglobular dentine.
研究了前磨牙横切面上划痕深度的变化。划痕由维氏金刚石产生，划痕过程中的垂直偏差通过电感式距离记录仪测量，并由xy记录仪持续记录。牙釉质所有区域的划痕深度几乎恒定，变化极小。在牙本质中，变化也很小，其恒定程度大于牙釉质。最大深度在球间牙本质中测得。
