Examining the effects of retraction cords on gum health
The Impact of Retraction Cords Used in Fixed Prosthodontics on the Gingival Margin Level in Humans: A Clinical Study.
NA · University of Jordan · NCT05949073
This study is testing how different types of dental retraction cords affect gum health in healthy people to see if they cause any problems or help during dental procedures.

What this trial studies
This study investigates how different types of retraction cords, used for varying durations, affect the gingival margin level in healthy individuals. It aims to assess both immediate and delayed effects of these cords on gingival recession and overall periodontal health. By analyzing the impact of mechanical and chemo-mechanical displacement methods, the study seeks to fill knowledge gaps regarding the safety and efficacy of retraction cords in dental procedures. Participants will undergo specific interventions involving non-impregnated and impregnated retraction cords to determine their effects on gum tissue.
Who should consider this trial
Good fit: Ideal candidates are healthy adults aged 18-50 with a lower first molar requiring full coverage restoration and healthy periodontal conditions.
Not a fit: Patients with existing gingival or periodontal diseases, systemic health issues, or those who smoke heavily may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to improved dental practices that minimize gum recession during restorative procedures.
How similar studies have performed: While there is limited research specifically on the effects of retraction cords, similar studies on gingival displacement methods have shown varying degrees of success.
