The technique used to iden- tify the spatial relation of an object is called the cone or tube shift technique. Other names for this procedure are the buccal object rule, Clark’s rule, and the SLOB (same lingual, opposite buccal) rule. Proper application of the technique allows the dentist to locate additional canals or roots, to distinguish between objects that have been superimposed and between various types of resorption, to determine the buccal-lingual position of fractures and perforative defects, to locate foreign bodies, and to locate a.

Thus, for teeth with porcelain restorations ligation with dental floss is recom- mended as an alternate method to retract the dam and tis- sues, or the adjacent tooth can be clamped. In the split-dam method, two overlapping holes are punched in the dam. A cotton roll is placed under the lip in the mucobuccal fold over the tooth to be treated. The rubber dam is stretched over the tooth to be treated and over one adjacent tooth on  Conservative Dentistry and Endodontics 5 each side. The edge of the dam is carefully teased through 26. Identify the equipment shown in the color plate. the contacts on the distal sides of the two adjacent teeth. Dental floss helps carry the dam down around the gingiva.
