What is the effect of gingival displacement with cord?

Gingival displacement with cord is a technique used in dentistry, particularly in preparation for making impressions for crowns and inlays. The primary purpose of using gingival retraction cord is to manage the gingival tissue effectively during the impression process.

By displacing the gingival tissue, the cord creates a space between the tooth and the gum. This enables the dental professional to gain better visibility and access to the margins of the preparation. Consequently, this technique does help in reducing the risk of injury to the gingiva during the impression-taking process. When the gingiva is retracted properly, there is less likelihood of the impression material coming into contact with the sensitive gum tissue, which can lead to trauma or irritation.

This action not only ensures a clearer view of the tooth and surrounding structures but also helps to prevent potential complications that can arise from disturbing the delicate gingival sulcus. The technique is crucial in achieving an accurate impression that contributes to the fit and longevity of the prosthetic restoration.

In summary, while the other options may touch on aspects of the gingival displacement process, they do not primarily encapsulate the main effect that displacement with cord aims to achieve, which is to reduce the possibility of gingival injuries.
