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.

Inclusion Criteria: Inclusion criteria: * ≥ 18 years of age. * Single extraction of non-molar teeth with periodontally healthy adjacent teeth. * Non-contributory medial history. * Non- restorable teeth indicated for extraction. * Requiring alveolar preservation after tooth extraction prior to placement of dental implant. * Participants that are eligible for immediate implantation, yet having factors that are hindering these patients from immediate placement of an implant at the time of extraction (ex: Financial related factors - psychological psychological factors - time related factors). * Cooperative patients who are willing to commit for 3 months follow up. Exclusion Criteria: * Pregnant female. * Acute infection at extraction site. * Systemic conditions affecting healing (e.g., diabetes, medications as bisphosphonates...) * A participant who had radiotherapy or chemotherapy. * Psychiatric patient, or with a learning disability, or unable to give consent.
