Retraction CordĀ
A retraction cord is a small cord used in dentistry to temporarily push the gingival (gum) tissue away from the tooth, primarily for:
š¦· Purpose:
Ā
- Exposing the margins of a tooth before taking an impression (e.g., for crowns, bridges).
- Controlling bleeding and moisture in the area.
- ProvidingĀ access to subgingival margins (edges of tooth preparation below the gumline).
š Sizes Explained (000, 00, 0, 1, 2):
These numbers refer to the diameter or thickness of the cord. The more zeros, the smaller and thinner the cord:
| Size | Thickness | Best For |
|---|---|---|
| 000 | Ultra-fine | Extremely thin tissue, pediatric or anterior teeth |
| 00 | Very fine | Thin gingival, minimal displacement needed |
| 0 | Fine | General use in small or anterior teeth |
| 1 | Medium | Most common for general crown and bridge work |
| 2 | Thick | Deep sulcus, posterior teeth, heavy displacement |
š Other Characteristics:
Ā
- Impregnated cords: Soaked with agents like epinephrine or aluminum chloride to help with hemostasis (control of bleeding).
- Non-impregnated cords: No chemicalsāsafe for patients with sensitivities.
- Braided, knitted, or twisted: Different textures for how they compress and stay in place.
