Poor Aesthetic of Existing Restoration of Tooth
Conditions
Brief summary
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.
Detailed description
On conventional technique we normally use a cord for gingival displacement. On the other hand, on cordless technique do not require this need.
Interventions
PROCEDUREGingival displacement
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.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Interleukins concentration on gingival crevicular fluid | Before and 1 day after gilgival displacement |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Periodontal indices | 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
| Measure | Time frame | Description |
|---|---|---|
| Self-reported unpleasant flavour and pain | 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. |
