Aim: Gingival deflection techniques can be classified as mechanical, mechanochemical, surgical, or any combination. Comparative evaluations of gingival retraction systems are done rarely mainly because there is no consensus on the evaluation criteria. Therefore, this study aimed to evaluate the efficacy of three different gingival retraction systems, i.e., Magic Foam Cord, expasyl paste, and aluminium chloride-impregnated retraction cord. Materials and Methods: Following impressions, obtained casts were measured for gingival sulcus opening width under optical microscope (with imaging system software). The presence of bleeding after removal of material, ease of procedure, and patient's comfort were also evaluated. The data collected were tabulated and subjected to statistical analysis. Results and Conclusion: Evaluation of the clinical efficacy is relatively difficult because of the lack of appropriate measuring tool. In addition, choice of appropriate gingival retraction system is still a dilemma for the operator. Moreover, a particular clinical situation may indicate the specific technique.
