The Effect of Using Different Scaffolds in Retreated Teeth on The Clinical and Radiological Success of Regenerative Endodontic Treatment

This clinical study aims to compare the clinical and radiographic outcomes of four different scaffolds used in regenerative endodontic treatment of previously root canal-treated permanent teeth requiring retreatment. Participants will be randomly assigned to one of four groups based on the scaffold used: induced blood clot, injectable platelet-rich fibrin (i-PRF), advanced platelet-rich fibrin (A-PRF), or advanced platelet-rich fibrin plus (A-PRF+). All participants will receive the same root canal disinfection and restorative procedures, with the scaffold type differing between the groups. Participants will be evaluated clinically and radiographically at 3, 6, and 12 months after treatment. The study will compare the groups in terms of the resolution of clinical signs and symptoms and changes observed on radiographic and cone-beam computed tomography images.

Endodontic Success of Coronally Sealed Non-obturated Canals, Regeneration-based Canals

Statement of problem: Limitations and drawbacks associated with root canal obturation have the potential to impair periapical healing especially in the absence or delay of a proper coronal seal. Aim of the study: Evaluate the endodontic treatment success in terms of resolution of signs and symptoms and periapical status using conventional periapical radiographs following two different treatment modalities, Coronally Sealed Non-obturated Canals, Regeneration-based Non-obturated Canals and comparing them to a control group of gutta percha obturated canals. Materials and methods: Forty-eight Patients with mature, double canal, vital upper first premolars with irreversible pulpitis. In a single visit, the tooth is to be anesthetized, isolated and an access cavity is to be performed. Mechanical preparation of root canals is to be performed using the standardized technique reaching apical canal preparation to size #35 with taper of 4%. The patients will then be divided into three groups (n=16). Group One (Control group) will be conventionally obturated with gutta percha and resin sealer, and coronally sealed with glass ionomer and composite restoration. Group Two will be left unobturated and will receive a seal of MTA 2-3 mm below the CEJ then coronal restoration of glass ionomer and composite restoration. In Group Three, an induction of bleeding will be performed by apical violation and the tooth will receive a seal of MTA 2-3 mm below the CEJ then coronal seal of glass ionomer and composite restoration.

Maximum Occlusal Bite Force of Necrotic Permanent Teeth Treated by Regenerative Technique: Randomized Clinical Trial

Further investigation is warranted to ascertain whether the regaining of sensibility and nerve function in regenerated teeth leads to the re-establishment of the proprioceptive protective mechanism inherent in vital teeth. Hence, the primary objective of this prospective randomized clinical trial is to conduct a comparative analysis of the potential effects of pulp revascularization in comparison to conventional endodontic treatments, either RCT or apexification on the Maximum occlusal bite force (MBF) in both immature and mature necrotic permanent teeth. Methods: Upon satisfying the predetermined criteria for inclusion, a total of 184 patients will be recruited for this prospective clinical trial. The study will consist of two groups, specifically Group I: Mature teeth and Group II: Immature teeth, with a sample size of 92 participants in each group. The participants will be assigned randomly to one of the two treatment modalities per group. Group I: will undergo treatment with RCT/revascularization, while Group II will receive MTA plug/revascularization encompassing both mature (n=92) and immature teeth (n=92). MBF will be measured on the selected necrotic teeth prior to clinical intervention, this measurement will be conducted using a portable occlusal force gauge (GM10). Following the completion of therapy, MBF measurements will be repeated at 6 and 12 months to assess long-term outcomes. Subsequently, the collected data will undergo comprehensive analysis.
