NCT07546773
Achieving effective root canal disinfection while minimizing postoperative pain is a critical goal in endodontic therapy. Advanced irrigation protocols, such as ultrasonic activation, laser activation, negative pressure irrigation (PulpSucker device), and mechanical activation (Easy Clean device), have shown promise in enhancing bacterial reduction within the root canal system. However, their impact on postoperative pain has not been fully explored. This randomized controlled clinical trial aims to compare bacterial reduction and postoperative pain levels in infected root canals using four different irrigation protocols. The study will use metagenomic analysis to evaluate changes in bacterial community composition and the Visual Analogue Scale (VAS) to assess patient-reported pain levels at multiple time points postoperatively.
NCT05739682
The aim of this study is to compare the effect of antimicrobial-corticosteroid mixture and cryotherapy as final root canal irrigating solutions on post-instrumentation pain in single-canal teeth with necrotic pulps.

Root canal preparation is one of the most important stages in root canal treatment. Nowadays, the use of Nickel-Titanium(Ni-Ti) rotary instrument systems for root canal expansion is becoming very popular. The force required to rotate the Ni-Ti file is defined as the torque force and is considered a parameter for the stress produced within the canal. Ni-Ti rotary instruments can be used with a wide speed scale between 150 rpm (rotary per minute) and 40,000 rpm in conventional endodontic engines. Low torque and speed values mean low pressure applied by the instruments in the root canal. With low forces and vibrations, motor noise is generally negligible, and the instruments can easily shape most root canals in a reasonable amount of time and with minimal mechanical stress (in medium-easy canals). The use of lower torque values has been shown to reduce cyclic fatigue of Ni-Ti rotary tools. With reduced cyclic fatigue, the risk of instrument breakage in complex root canal morphologies is minimized and complications that may occur during root canal treatment are reduced. However, with low torque and speed values, cutting efficiency decreases and the process time increases as the instrument advances in the canal and during possible treatment. Decreasing cutting efficiency may also result in the operator applying force to move through the canal. With the applied force, the friction resistance within the canal increases and the heat produced increases. For this reason, it is thought that the risk of post-operative pain may increase during or after the procedure. The aim of this study is to investigate the incidence of post-operative pain and procedure time using the visual analog scale (VAS) among groups where low torque and speed values were applied during the use of the Ni-Ti rotary instrument system.
NCT03376984
The purpose of this study is to to compare root canal therapy success between two root canal filler materials: 1) gutta percha (GP), 2) gutta percha modified with nanodiamonds and amoxicillin (NDGX). Gutta percha is the current standard root canal filler material used during non-surgical root canal therapy (RCT). Gutta percha modified with nanodiamonds and amoxicillin is an investigational root canal filler material, not yet FDA approved for use as described in this study. The safety and usefulness of NDGX is being tested in this study in comparison to the current standard of care, gutta percha (GP).
NCT01827098
Both methods tested in this study disinfect the non-vital root canals and induce blood clot formation inside the root canal. One method places calcium hydroxide inside the root canal after disinfection and the blood clot is induced four weeks later. The other method performs disinfection and induction of blood clot in one appointment. The investigators hypothesize that both methods will obtain the same success rate in eliminating infection, increase in root length and canal walls thickness.
NCT03533231
This Study Was Made to Evaluate the Antibacterial Effect of Different Antibacterial Combinations on Revascularization Process in Permanent Anterior Immature Teeth. Immature Necrotic Permanent Maxillary Incisors (n = 40) of Patients 8-18 Years Old Were Divided Into 4 Equal Groups (Each n = 10) According to the Intracanal Medicament: Group 1 Was Treated With Triple Antibiotic Paste (TAP), Group 2 Was Treated With Ciprofloxacin + Propolis Paste (CP), Group 3 Was Treated With Ciprofloxacin + Metronidazole Paste (CM), Group 4 Was Treated With Propolis + Metronidazole Paste (PM). Cases Were Followed at Regular Intervals up to 18 Months Clinically and Radiographically.
