Background: The chemico- mechanical method of using a retraction cord impregnated or soaked in various chemicals is the most frequently used method. The present study was conducted to evaluate the level of gingival displacement produced by three different gingival displacement systems such as aluminum chloride retraction cords, expasyl, and tetrahydrozoline soaked retraction cord. Materials & Methods: The present study was conducted on 60 patients of both genders. Baseline impressions were made in which no gingival displacement was done (control group). Patients were divided into 3 groups of 15 each. In group I patients, aluminum chloride retraction cord was used, in group II patients, tetrahydrozoline displacement system was used and in group III patients, expasyl displacement system was used. Impressions in all patients were made. Sample was studied under a microscope with X20 magnification. The values of gingival displacement for all the specimens were recorded in μm2. Results: In control group, retraction achieved was 25814 μm2, in group II was 143452 μm2, and in group III was 49625 μm2. The difference was significant (P< 0.05). Conclusion: Authors found that aluminum chloride displacement cord showed the maximum displacement. Expasyl showed the least amount of displacement.
