Clinical Trial of Two Techniques for Gingival Displacement

Regardless of the selected technique for dental impression, gingival displacement is an essential procedure specially when making impressions of subgingival finishing lines, because a moisture-free sulcus is a requirement for an effective impression.

The objective of this randomized clinical study is to evaluate the efficacy of the conventional and cordless gingival displacement (GD) techniques.

About this study

On conventional technique we normally use a cord for gingival displacement. On the other hand, on cordless technique do not require this need.

Treatment and study plan

Gingival displacement

Procedure

Gingival displacement is a dental procedure that allows exposure of the finishing line of a dental cavity in order to produce a well-adapted restoration.

Primary outcomes

  1. Interleukins concentration on gingival crevicular fluid

    Time frame: Before and 1 day after gilgival displacement

Secondary outcomes

  1. Periodontal indices

    Time frame: Before, 1 day after and 10 day after gingival displacement

    Periodontal indices (attachment level, gingival bleeding and plaque index) were evaluated before and after gingival displacement by the both techniques.

Other outcomes

  1. Self-reported unpleasant flavour and pain

    Time frame: Immediatelly after interventions

    Also were evaluated subjective parameters (unpleasant flavor and pain) self-reported by the volunteers during gingival displacement. These subjective outcomes were collected using the visual analogic scale.
