Aims and Objectives: Newer gingival displacement materials such as magic foam are available now and hence, there is a need to assess those materials with the commonly used gingival retraction cord. This study aimed to evaluate the gingival displacement width obtained using plain retraction cord and magic foam cord on an unprepared mandibular molar. Materials and Methods: Twelve patients in the age group of 20-30 years satisfying the inclusion criteria were selected. For each patient, pre-and post-displacement impressions were made using regular body addition silicone. The predisplacement impression served as the control. Gingival displacement procedures were performed in the buccal gingival sulcus of unprepared 1 st mandibular molar. Both pre-and post-displacement impressions were sectioned and evaluated using a profile projector. The values were tabulated and analyzed using SPSS 16 software. Results: There was an increase of 62.4% in width of the gingival sulcus when displaced with cord and 61.6% increase using magic foam cord. The retraction cord provided 0.8% more gingival displacement when compared to the magic foam cord, which was not statistically significant. Conclusion: Weighing the pros and cons, it can be concluded that magic foam cord could be preferred over plain retraction cord as both methods provided almost the same amount of gingival retraction, and magic foam cord caused less trauma to the gingiva, was less time consuming, and easy to use.
