Background: The present study evaluated aluminum chloride retraction cords and expasyl as gingival retraction system. Materials and Method: The present study was conducted on 40 edentulous patients. Patients were divided into 2 groups of 20 each. In group I, aluminum chloride retraction cords and in group II expasyl retraction cord was used. Results: In group I, retraction was aluminum chloride and in group II it was expasyl. The mean gingival displacement in group I was 812.2 microns and in group II was 614.2 microns. The difference was significant (P< 0.05). Conclusion: Author found that maximum gingival retraction was achieved with aluminum chloride retraction cord as compared to expasyl.
