What's being measured

Primary outcomes are the specific endpoints the trial is designed to prove or disprove.

• Horizontal Gingival Displacement
  Time frame: Baseline and 1 week post-displacement
  The amount of tissue movement away from the tooth surface (laterally). Measured by comparing stereomicroscopic images of polyvinyl siloxane (PVS) impressions taken before and after displacement. The horizontal gap is measured in millimeters.
• Vertical Gingival Displacement
  Time frame: Baseline and 1 week post-displacement
  The amount of tissue movement in the vertical direction (apically) after using each gingival displacement method.

Sponsor's own description

This clinical study is being conducted to compare four different methods used to temporarily push the gums away from the teeth during dental procedures. This process, called gingival displacement, is important for dentists to clearly see and work around the tooth when placing crowns or taking impressions. The four methods being studied include: A retraction cord soaked in a special solution, A retraction paste in a capsule, A retraction paste applied with a cap, A soft tissue laser (called a diode laser). Each method is applied to teeth that need crown treatment. The goal is to find out which method moves the gum tissue the most effectively, and which one causes the least bleeding. Fifty-two teeth in total were treated using one of these four methods. Before and after treatment, gum measurements were taken to evaluate how much the gums moved and how much bleeding occurred. By studying these methods, the researchers hope to help dentists choose the most effective and least invasive technique for each patient's needs.
