Class II Cavity Prep

A Class II carious lesion develops apical to the contact area on the proximal surfaces of posterior teeth. The procedure for the removal of the carious lesion is the same as that of a class I. The first step is the development of the ideal cavity preparation. By doing an ideal cavity preparation, the extent of the carious lesion on the pulpal, lateral, and axial walls is seen. If there is any remaining carious lesion, it is removed. Any remaining carious lesion is removed only after establishment of the ideal internal and external outline forms.
