Changing concepts in Class I and II cavity preparation. From the time G V Black, father of Operative Dentistry outlined the principles of cavity preparation, and stressed on "extension for prevention", dentistry has taken long strides. Contact area carious lesion Proximal view Vertical section - Columbia CTL CLASS II CAVITY PREPARATION CHARACTERISTICS OF AN IDEAL CLASS II Contact area carious lesion Proximal view Vertical section - Buccal view Class II carious lesions are diagnosed using bitewing radiographs. In reading a bitewing radiograph, it is important to know that a proximal lesion that appears to be 2/3 or more through enamel toward the DEJ has actually penetrated the DEJ. It is also important to remember that even if caries have slightly penetrated DEJ, they can still be remineralized ...

Initial Tooth Preparation. The general concept of the initial tooth preparation is presented in Chapter 14, and it applies to the pin-retained complex amalgam restorations described here. When caries is extensive, reduction of one or more of the cusps for capping may be indicated.
