[The variation of the depth of the cervices in the ground surface of the tooth].
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.
