Comparison of pressure generated by cordless gingival displacement materials.

Statement Of Problem: Because pressure generated by a displacement cord may traumatize the gingiva, cordless gingival displacement materials are available to the clinician as atraumatic alternatives. However, whether the pressures produced by the different systems are equivalent is unclear.

Purpose: The purpose of this study was to investigate the pressures generated by 4 different cordless gingival displacement materials.
