The main purpose of a gingival retraction cord is to provide a dentist with a clear working view of a tooth prior to making a dental impression.
What is the purpose of gingival retraction?
The goal of gingival retraction is to atraumatically displace gingival tissues to allow access for impression material to record the finish line and provide sufficient thickness of gingival sulcus so that the impression does not tear off during removal.
How is gingival retraction done?
The most common method in gingival retraction which is fast, simple and inexpensive is cord packing that can be used separately or in combination with hemostatic agents in two techniques: single cord or dual cord [14]. Retraction cord penetration depth is influenced by the sulcus depth and periodontal status.
