Summary
This trial tests three common ways to move the gums aside (gingival displacement) when taking impressions for dental crowns. 39 adults needing a single front tooth crown will receive one of three methods: a retraction cord, a retraction paste, or a cord plus hemostatic gel. Researchers will measure how well each method opens the gum sulcus and check for bleeding and pain.
