Abstract
Aim: This study is done to evaluate clinical efficacy of Expasyl and medicated retraction in subgingivally prepared teeth. This is done by evaluating vertical displacement of gingiva. Method: In the present study, total 30 subjects were selected. Clinical efficacy of Expasyl retraction system and medicated cord retraction system were studied for adequate vertical gingival displacement by direct assessment of the sulcus dilation on the prepared teeth with help of flexible measuring strip pre and post retraction, which includes paired abutments of any one segment of either maxillary or mandibular arch. Statistical analysis was done to compare two systems.
Result: Expasyl retraction technique was more effective in vertical gingival retraction (mean- 0.32 mm) than medicated retraction cord technique (mean-0.30mm) with a t value at 1.175 and P - value of 0.25 mm. conclusion: The amount of vertical gingival retraction obtained by Expasyl and medicated cord was significantly similar but Expasyl retraction system is not cost effective when compared with cord system.
