Influence of the Gingival Condition on the Performance of Different Gingival Displacement Methods-A Randomized Clinical Study.

This randomized clinical study examined the influence of the gingival condition-healthy versus mild inflammation-on sulcus representation and possible gingival recession for two gingival displacement procedures prior to conventional impression making. The interventions double cord technique or a kaolin paste containing aluminum chloride were applied to 40 probands. The opposite quadrant served as intrapersonal reference (split-mouth design).
