Applying the chisel to the surface, the underminedenamel is split away, as is indicated in Fig. 56. The buccalwall is planed until it is in the axial plane, and the cavo-surface angle bevelled. It is not necessary to extend thecavity to the lingual beyond the point where sound dentineis reached, but the disintegrated enamel on the surface mustbe removed. The enamel wall is, therefore, inclined about6 centigrades lingually from the axial plane, and it is not Fig. 57
