    Statement of Problem: A gingival retraction system may be soft tissue friendly or could be easy to use or could be the tried and tested one. However, when compared to the results they produce, the clinical application is questioned. Aim: The aim of this study is to evaluate the amount of gingival retraction produced by expasyl retraction paste and plain retraction cord. Methods and Materials: This study included 39 subjects. After abutment, teeth were prepared for fixed partial denture, plain retraction cord or expasyl retraction paste was placed into the sulcus of the prepared teeth, and time taken for application was recorded and bleeding was noted after removal of retraction material. Gingival sulcus width was measured by travelling microscope. The gingival recession was measured using digital caliper. Results: The mean gingival width of retracted sulcus in both the groups showed no statistically significant difference between the two (P < 0.05). The mean time taken for application and hemorrhage of expasyl paste (99.34 min, 5.1% bleeding) was significantly less than plain retraction cord (221.89 min, 74.4% bleeding). In both phases, the gingival index and gingival recession in the cord group were significantly higher than expasyl paste group. Conclusion: From the study results, amount of gingival retraction with the use of expasyl retraction paste is almost similar in comparison to plain retraction cord; expasyl retraction system appears to produce less hemorrhage and needs less clinical time for application. The effect of retraction system on soft tissue health (plaque index, bleeding on probing, and mean gingival recession) in the expasyl paste group was significantly better than cord group. Clinical Significance: Retraction with expasyl paste producing similar amount of lateral displacement of the gingival margin, therefore based on the beneficial effects, it may be recommended for absorption of intraoral fluids and exerting moderate pressure on gingival tissue.
