MMP-2/3 and Periapical Healing Outcomes

This prospective randomized clinical study will investigate the association between MMP-2 and MMP-3 gene polymorphisms and radiographic healing outcomes following nonsurgical root canal treatment in patients with chronic apical periodontitis. A total of 50 patients will undergo standardized endodontic treatment and will be followed for 12 months. Genotyping will be performed using baseline DNA samples, and periapical healing will be assessed using the Periapical Index (PAI). The relationship between genetic variations and treatment outcomes will be analyzed to determine whether host-related genetic factors influence healing patterns after root canal therapy.

Using Platelet-rich Fibrin in Regenerative Endodontic Treatment in Mature Permanent Teeth

This study aims to evaluate the antibacterial effects of injectable platelet-rich fibrin (i-PRF) in vitro, and to assess the clinical and radiographic outcomes of using advanced platelet-rich fibrin (A-PRF+) and i-PRF in regenerative endodontic treatment of mature permanent teeth with necrotic pulp. The study will compare the effectiveness of PRF-based treatment with conventional blood clot-based regenerative endodontics.

Sonic vs Passive Ultrasonic Irrigation for Chronic Apical Periodontitis

This randomized, controlled, double-blinded clinical trial aims to directly compare the efficacy of Sonically Activated Irrigation (SAI) versus Passive Ultrasonic Irrigation (PUI) in the root canal treatment of teeth with chronic apical periodontitis, analyze potential influencing factors, and thereby identify a highly effective and safe root canal irrigation protocol. The ultimate goal is to provide an evidence-based rationale for optimizing irrigation technique selection and overall treatment strategies for chronic apical periodontitis.

Effect of Different Root Canal Sealers on Oxidative Stress Markers

The goal of this clinical trial is to primary purpose investigate and compare oxidative stress markers in patients with chronic apical periodontitis treated with different root canal paste in a single session. The main questions it aims to answer are: Is there a change in oxidative stress markers measured from saliva after root canal treatment? Is there a difference between the change of oxidative stress markers in patients using different root canal sealers after root canal treatment? Researchers will compare bioceramic-based and epoxy resin-based root canal sealers to see if there are significant differences in oxidative stress markers measured from patients' saliva after root canal treatment. * Participants will be informed about all procedures before starting the clinical process. * Participants are expected to allow saliva sampling two times: first sample will be collected on root canal treatment session and second sample will be collected on the 30th day after root canal treatment. * Participants will be informed in writing about the treatment procedure before starting the clinical process. * Participants are expected to sign the informed consent form on a voluntary basis.
