About

To achieve harmony between restoration and surrounding periodontium, soft tissue management plays a pivotal role. Various Gingival displacement techniques show varying results in achieving the goals of displacement. The most preferred method of displacement by dental practitioners is through conventional retraction cord made up of cotton, which besides its advantages, poses certain drawbacks, including low tear strength, high friction, and fiber remnants within the sulcus.

Polytetrafluoroethylene (PTFE) retraction cord, is a fluoropolymer, known for its high tear strength, low friction, and bio-compatibility.

This study aims to determine the difference of horizontal gingival displacement between PTFE and conventional retraction cord.

Participants inducted in this study will be assessed for eligibility. qualifying subjects will receive crown preparation for Porcelain-fused to-metal crown. subjects will then be randomly allocated to either of the two arms of intervention. After making a pre-displacement impression, Retraction cord will be applied for 3 minutes, then removed to record post-displacement impression.

the difference in pre and post-displacement mean gingival sulcus width will be assessed by a stereomicroscope using image analysis software.
