Comparative evaluation of gingival displacement produced by three different gingival retraction materials

Abstract

Aim: To compare and evaluate the gingival displacement produced by three different gingival retraction materials. Materials and Methods: A study was conducted to evaluate the gingival displacement produced by three gingival retraction materials. 12 subjects were selected for the study. T-stat retraction paste system (Nexobio co.Ltd,Korea), 3M ESPE Retraction Paste (3M Deutschland GmbH, Germany), Roeko Stay- put retraction cord (Coltene Whaledent Pvt. Ltd.) were used in the study. Results: Out of the three materials used, lateral displacement was maximum with the Stay-put retraction cord followed by 3M retraction paste and least by T-Stat retraction paste. All the materials produced acceptable amount of vertical gingival retraction. When compared Stay-put retraction cord was found to be most effective among the three materials. On comparison of the cordless retraction materials, it was found that the material which was more viscous in consistency (3M retraction paste) was able to produce more lateral gingival displacement than the material having less viscosity (T-stat retraction paste) even though both the cordless materials provided almost similar amount of vertical gingival displacement. The overall gingival retraction produced by the Stay-put cord was the highest followed by 3M retraction paste and least by the T-stat retraction paste.
