A clinical study on the effects of cordless and conventional retraction techniques on the gingival and periodontal health.

Aim: To investigate the influence of two cordless techniques on the periodontium in comparison with conventional cords.

Material And Methods: Dental students (n=60) with healthy gingival conditions were recruited - an expanding poly vinyl siloxane material (Magic Foam Cord), a paste-like material (Expasyl), and a conventional retraction cord (Ultrapak) were applied on the buccal aspects of three premolars of each subject. Probing depth, clinical attachment level, gingival index (GI), plaque index, mobility, bleeding, and sensitivity were assessed at baseline, and at 1 and 7 days after application.
