Background & Objective: Gingival-displacement is carried out for successful clinical outcome of the restoration; hence the objective of the study is to investigate the clinical outcome of 3 different gingival-displacement systems in terms of (1) the amount of displacement and (2) the presence of gingival recession 14 days post-displacement, if any. Methods: 20 completely dentate male and female individuals with healthy periodontium were selected. Gingival displacement was done using Ultrapak (gingival-displacement Cord), Expasyl (15% aluminium chloride paste), and Merocel (polyvinyl acetate strips) on selected teeth as per manufacturer’s instructions. Impressions were made with Monophase addition silicone immediately before gingival-displacement, immediately after gingival-displacement and on 14th day post-displacement. Evaluation was done under a 3-D microscope, by comparing the samples of (1) before and after group, and (2) before and 14th day post-displacement group. Results and Interpretation: Tukey’s Post Hoc test revealed statistically significant results for Merocel when compared with Expasyl and Ultrapak with difference in mean value being 0.455, 0.273, and 0.286mm respectively (p-value<0.001). There was no statistically significant difference between Expasyl and Ultrapak, also between the samples of before and 14th day post-displacement group. Thus there was no trauma to gingiva as observed in 14th day post-displacement group. Conclusion: Merocel produced the maximum amount of gingival-displacement than Expasyl and Ultrapak, and also all the materials used did not affect the gingival health adversely.
