What can be a consequence of overpacking cord during dental procedures?

Overpacking the retraction cord during dental procedures can lead to multiple negative outcomes, which is reflected in the correct answer.

When the retraction cord is excessively packed, it can fail to properly displace the gingiva, resulting in inadequate retraction. This undermines the purpose of the cord, which is to create a clear working field and facilitate accurate impression-taking or preparation of the tooth.

Moreover, overpacking can distort the impression material. If the cord is too tight, it can create pressure points that lead to an inaccurate representation of the prepared teeth and adjacent structures. This distortion can compromise the fit and function of the prosthetic being created.

Lastly, repeatedly overpacking can contribute to gingival recession. The excessive pressure exerted on the gingival tissues may lead to irritation and eventual withdrawal of the gingiva away from the teeth. This not only affects aesthetics but can also lead to sensitivity and other periodontal issues.

Thus, overpacking the cord can have a cascading effect, resulting in all of the mentioned consequences, making the comprehensive impact of this action significant in dental practice.
