Status Not yet recruiting

Clinical Trial Summary

The goal of this observational study is to define the role of apical shaping and irrigation activation on root canal cleanliness. The main questions it aims to answer are: - does the effectiveness of irrigation activation depends on apical shaping? - can a similar success be achieved by increasing apical shaping without irrigation activation Participants will [describe the main tasks participants will be asked to do, treatments they'll be given and use bullets if it is more than 2 items].

Clinical Trial Description

The aim of this study is to evaluate the effect of apical enlargement with two different diameters on the intraradicular microbiota of teeth with chronic apical periodontitis lesion before and after passive ultrasonic irrigation activation using ddPCR analysis in vivo.The study was planned as a randomized controlled clinical trial. We are planning to include 24 patients who was referred to the Istanbul Medipol University Faculty of Dentistry Endodontic Clinic with the need for root canal treatment, with asymptomatic chronic apical periodontitis. 24 patients will randomly be assigned to two groups according to the apical shaping size during root canal treatment: 25/.04 and 35/.04. Microbiological sampling of the teeth will be done with paper cones in three steps during the root canal treatment: 1. Sterility control samples (SR1) from the tooth surface after cavity preparation, 2. The first microbiological sample (S1) from the root canal after the initial file reaches the working length. 3. The second microbiological sample (S2) from the root canal after the shaping and irrigation of the root canal is finished. 4. The third microbiological sample (S3) from the root canal after the irrigation activation in the root canal is finished.The samples will be sent to the genetic analysis laboratory for further analysis in the cold chain using a Droplet Digital PCR. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
