Background:Marginal adaptation plays an important role in the long-term success of the restoration, and failure to achieve the same can result in ill-fitting crowns. The present study determined the gingival displacement resulted from different gingival displacement systems. Materials & Methods: 40 patients were divided into 4 groups of 10 each. In group I patients, aluminum chloride retraction cord was used, in group II patients, tetrahydrozoline displacement system and in group III patients, expasyl displacement system and in group II no displacement system was used (control). Impressions in all patients were made. Sample was studied under a microscope with X20. Results: In group I retraction achieved was 142125 μm2 , in group II was 142104 μm2 , in group III was 49321 and in group IV was 25432 μm. 2 The difference was significant (P< 0.05). Conclusion: Aluminum chloride displacement cord showed the maximum displacement as compared to other retraction system.
