Comparing two methods for preserving bone after tooth extraction

Evaluation of Post Extraction Hard Tissue Changes Following Ridge Preservation Using Partially Demineralized Dentin Block Versus L- PRF Block in the Esthetic Zone: A Randomized Controlled Pilot Trial

Not applicable Interventional Cairo University · NCT06275490

This study is testing two different ways to keep the bone strong after a tooth is taken out to see which method works better for patients with a tooth that can't be saved.

What this trial studies

This study evaluates the effectiveness of two different techniques for ridge preservation following tooth extraction in the esthetic zone: partially demineralized dentin block and L-PRF block. Patients with a single non-restorable tooth will undergo a thorough periodontal and radiographic examination before extraction. The study will measure post-extraction hard tissue changes using various dental imaging techniques and clinical assessments. The goal is to determine which method better maintains bone structure after tooth removal.

Who should consider this trial

Good fit: Ideal candidates are healthy adults aged 18 and older with a single non-restorable tooth in the esthetic zone.

Not a fit: Patients with systemic diseases affecting bone metabolism, heavy smokers, or those with infections at the extraction site may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve outcomes for patients needing tooth extractions by enhancing bone preservation, which is crucial for future dental implants.

How similar studies have performed: Previous studies have shown varying success with similar ridge preservation techniques, but this specific comparison is novel.
