Comparison of Connective Tissue and PRF in Gingival Recession

Aim: In this study, it was aimed to comparatively investigate the clinical and biochemical effects of subepithelial connective tissue graft and coronally advanced flap (SCTG + CAF) or titanium-prepared platelet rich fibrin and coronally advanced flap (TPRF + CAF ) in the treatment of Miller class I and II gingival recessions.

The Effect of Retraction Cord on the Surrounding Periodontal Tissues in Restorative Treatment

The goal of this clinical trial is to learn whether a retraction cord affects gum health when used during tooth restoration procedures. A retraction cord is a thin thread that dentists sometimes place between the tooth and the gum surrounding it, to gently push the gum aside so the restoration can be performed in a clean surface isolated from saliva. The study includes adult teeth with tooth damage near the gumline that has not been caused by decay, yet needs a restoration. The main research question is: Does using a retraction cord make a difference for gum health as opposed to not using one? Participants will be assigned into four separate groups. Two groups will receive a restoration with one type of bonding material, either with or without a retraction cord. The other two groups will receive a restoration with a different kind of bonding material, either with or without a retraction cord. Researchers will check gum health status before the restorations and again on days 1, 7, and 28. They will observe symptoms such as swelling in the gums, bleeding of the gums, and gum margin positions. A fluid sample from the area between the gum and tooth will be collected to test for molecules of inflammation.
