Regenerative endodontic treatment using demineralized dentin matrix versus RetroMTA for immature permanent single-rooted teeth.

Official title: Evaluation of Regenerative Endodontic Treatment for Immature Teeth Using Two Different Forms of Demineralized Dentin Matrix and RetroMTA: Randomized Controlled Clinical Trial

Run by Kafrelsheikh University · NCT07210359 · Data updated 2026-11-12

This trial will test whether two types of demineralized dentin matrix used as coronal barriers help immature permanent single-rooted teeth (ages 9–15) heal and continue root development better than RetroMTA.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are systemically healthy 9–15-year-olds with immature permanent single-rooted teeth diagnosed with irreversible pulpitis or pulpal necrosis who can attend scheduled follow-ups.

Probably not a fit

Patients with grossly decayed or fractured teeth needing post-and-core, large periapical lesions (>10 mm), significant root resorption, very narrow apical foramina (<1 mm), or major systemic illness are unlikely to benefit.

What this trial studies

This randomized split-mouth clinical trial will enroll 36 healthy patients aged 9–15 with immature single-rooted teeth diagnosed with irreversible pulpitis or pulpal necrosis. Participants are randomly assigned to three groups receiving revascularization with a blood clot scaffold and either RetroMTA, a DDM–TheraCal LC mixture, or TDM–Hydrogel as the coronal barrier. CBCT scans at baseline and at 3, 6, 9, and 12 months will be used to measure outcomes including root length, dentinal wall thickness, apex closure, dentin bridge formation, and lesion size. The trial is conducted at the Endodontic Department, Faculty of Dentistry, Kafrelsheikh University, under institutional ethical approval.

Why it matters

Potential benefit: If successful, DDM-based materials could provide a bioactive coronal barrier that improves root maturation and long-term tooth survival in immature teeth.

How similar studies have gone: Revascularization techniques using blood clot scaffolds and MTA-like materials have shown clinical success in promoting root development, while clinical evidence for demineralized dentin matrix as a coronal barrier remains limited and relatively novel.
