L'essai clinique NCT07501585 est une étude interventionnel pour Parodontite périapicale. Son statut actuel est : en recrutement. L'étude a débuté le 20 février 2026 et vise à recruter 46 participants. Dirigée par l'Université de Berne, l'étude devrait être terminée d'ici le 31 décembre 2028. Les données du site ClinicalTrials.gov ont été mises à jour pour la dernière fois le 30 mars 2026.
Résumé succinct
This randomized clinical trial (RCT) will evaluate the effectiveness of cross-linked hyaluronic acid as an adjunct to endodontic microsurgery in adult patients with apical periodontitis affecting maxillary or mandibular first molars. Participants previously treated with non-surgical endodontic therapy will be allocated to either endodontic microsurgery with cross-linked hyaluronic acid application (test group) or the...Afficher plus
Description détaillée
Background and Rationale:

Endodontic microsurgery is an established treatment for persistent apical periodontitis after non-surgical root canal treatment. Successful healing depends on appropriate surgical technique, infection control, and favorable soft and hard tissue regeneration. Cross-linked hyaluronic acid is a non-animal-origin biomaterial with hydrating, tissue-supportive, and bacteriostatic properties, and ...

ExpérimentalTest: endodontic microsurgery with hyaluronic acid
The endodontic microsurgery will be performed, then cross-linked hyaluronic acid will be added in the surgical area.
Acide hyaluronique
The endodontic surgery will be performed under the control of an operating microscope (Carl Zeiss Extaro 300). The operation will be performed under anesthesia, articaine + epinephrine. OFD (single flap approach Trombelli 2009 combined with entire papilla preservation technique Aslan et al., flap elevation, osteotomy, 3 mm root resection, the root cut will be made at an angle close to 90 degrees, the root cut will be...Afficher plus

Critère principal d'évaluation
Critères d'évaluationDescription de la mesurePériode
The healing of soft tissues will be evaluated by the Early wound healing score
The early wound healing index assesses periodontal soft tissue healing, usually around 1 week post-surgery, by evaluating flap closure, fibrin presence, and necrosis in 5 grades. It ranges from score 1 (complete healing) to score 5 (necrosis and pus)
4 days after surgery
Critère secondaire d'évaluation
Critères d'évaluationDescription de la mesurePériode
The postoperative pain will be evaluated by visual analogue scale VAS
The visual analogue scale is a mm scale from 0 (no pain) to 100 mm (maximal possible pain)
within the two first weeks after surgery
Periapical healing assessed on periapical radiographs according to the Molven's criteria
The Molven's criteria is a 2D radiographic classification system used to evaluate the healing outcome of apical endodontic surgery, four main categories exist: Complete Healing: Bone tissue is completely restored, and a normal periodontal ligament (PDL) space is visible. Incomplete Healing (Scar Tissue): The initial radiolucent area has reduced in size, but a small residual rarefaction remains, often characterized as a "scar". Uncertain Healing: A reduction in the size of the lesion has occurred, but it does not fit the criteria for complete or incomplete healing. Unsatisfactory Healing (Failures): The radiolucent lesion is unchanged, has increased in size, or appears newly developed, indicating failure.
3, 6, and 12 months post-surgery
Pericapial healing on cone beam computed tomography (CBCT) scans according to PENN's criteria
Healing of endodontic microsurgery assessed using CBCT imaging, categories: Complete Healing (Success): Full bone repair, with the periodontal space having a normal width. Limited Healing (Success): Bone regeneration, but the periodontal space over the resected root surface is slightly widened (but less than twice the width of non-involved root). Uncertain Healing (Failure): A small defect or continued radiolucency persists in the lamina dura around the root-end filling. Unsatisfactory Healing (Failure): No change or an increase in the size of the radiolucent area, with poor bone repair.
6 and 12 months post-surgery
Cortical plate healing
Cortical plate healing will be scored according to the RAC/B index: Score 0: Cortical plate not re-established. Score 1: Cortical plate is partially re-established. Score 2: Cortical plate is re-established
6 and 12 months post-surgery
