ABSTRACT
Objective To evaluate the marginal microleakage in class Ⅱ-restorations after use of targis inlay. Methods Ten extracted human molar teeth were prepared for MO(mesio-occlusal) and DO(disto-occlsa) cavities. In one type of cavity gingival margin was placed above the cemento-enamel junction (CEJ). In another type gingival margin was placed below the CEJ. Cavities were filled with targis inlays. All teeth were thermocycled 200 times between 0℃ and 56℃. Finally, all teeth were cut in mesial-distal direction with a band saw and the numbers of walls of cavities were determined under scanning electron microscope. Results There was no any microleakage in occlusal margin. The number of inlay microleakage of gingival margin placed below CEJ (30 %) was more than that of gingival margin placed above the CET (10 %) ( P
