Blood clot upgrade: new gel may regrow tooth tissue
NCT ID NCT07192289
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a gel made from a patient's own blood (platelet-rich fibrin) can help regenerate the inner part of infected or dead teeth in adults. 57 participants will receive either the gel or a standard blood-clot treatment. The goal is to see if the gel reduces infection and promotes healing better than the usual approach.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: Participants had a single-rooted tooth with necrotic pulp (negative response to electric pulp testing), with or without periapical pathology (acute apical periodontitis of pulpal origin, chronic periapical periodontitis, periapical abscess with sinus, periapical abscess without sinus), and gave their consent to participate in the study. Exclusion Criteria: Study samples will be excluded if any of the following criteria are met: * The tooth has had previous endodontic treatment. * The root apex is not fully developed, or there is root resorption/cracking/fracture. * The tooth has severe tooth loss and is indicated for extraction, or is indicated for restoration with a post or cast core after endodontic treatment. * The root canal is calcified. * The root canal curvature is greater than 25º. * The tooth has a periapical cyst or is associated with a jawbone cyst. * The tooth has a periodontal pocket deeper than 4 mm. * The tooth has no occlusal contact. * The patient is pregnant. * The patient has diabetes or HIV or other immunocompromised conditions.
