Evaluating the effects of vitamin C on bone preservation after tooth extraction

Official title: Evaluation of Dentin Graft and I-PRF With and Without Vitamin C for Post-extraction Socket Preservation. A Randomized Controlled Clinical Trial

Run by Cairo University · NCT06569264 · Data updated 2026-11-12

This study is testing if adding vitamin C to a bone graft after tooth extraction can help preserve bone better than just using the graft alone.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with non-restorable teeth requiring extraction and alveolar preservation prior to dental implant placement.

Probably not a fit

Patients with systemic conditions affecting healing, such as diabetes or those undergoing chemotherapy, may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to assess the impact of adding vitamin C to autogenous demineralized dentin graft and i-PRF on marginal bone loss following tooth extraction. Participants will be divided into two groups: one receiving the graft with vitamin C and the other receiving the graft without it. The study will evaluate clinical and radiographic outcomes over a six-month follow-up period. The hypothesis is that vitamin C may enhance osteoblast activity and improve soft tissue quality, leading to better socket preservation.

Why it matters

Potential benefit: If successful, this approach could lead to improved bone preservation and better outcomes for patients requiring dental implants after tooth extraction.

How similar studies have gone: While the use of vitamin C in bone preservation is promising, this specific combination of treatments has not been extensively tested in prior studies.
