Mikrobielle Belastung nach apikaler Vergrößerung bei asymptomatischen Zähnen mit periapikaler Läsion
Die Auswirkung der apikalen Vergrößerung auf die mikrobielle Belastung vor und nach der passiven Ultraschallaktivierung bei asymptomatischen periapikalen Zahnläsionen
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].

Detaillierte Beschreibung
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.

Studienpopulation
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, witj clinical and radiographic findings. The study will be carried out in Istanbul Medipol University Faculty of Dentistry Endodontic Clinic, and patients with appropriate criteria will be informed about the treatment to be performed and their consent will be obtained. In this observational type study, patients treated by the same physician will be followed.

Group 1- One Curve Mini 25/0.4
Root canal shaping will be completed with a heat-treated nickel titanium OneCurve Mini #25/0.4 rotary file (Micro-Mega, Besancon, France) after reaching the apical region with #10 K stainless steel files (Dentsply Maillefer, Ballaigues, Switzerland). The irrigation solution will be used by adapting an ultrasonic tip (IRRI S 21/25; VDW, Munich, Germany) to an ultrasonic device (VDW Ultra; VDW, Munich, Germany). The tip will be activated a total of three times, each cycle lasting 20 s and involving the use of 1 ml of 3% NaOCl. Then 2 ml of 17% EDTA solution will be activated for 1 minute as described above. The ultrasonic tip will be placed 2 mm shorter than the working length without touching the canal walls. |

does apical shaping size affect the microbial load in the root canal after shaping and irrigation finishes? microbial load after two different apical shaping size will be compared between two groups. Droplet Digital PCR will be used to measure and compare the microbial load within the root canal before and after irrigation protocol in each group to measure this outcome. |

does irrigation activation affect the microbial load in the root canal? microbial load after chemomechanical cleaning of the root canal and after the irrigation activation will be compared. Droplet Digital PCR will be used to measure microbial load before after irrigation activation in each canal to see its effect on reduction fo microbial load within the root canal. |

does apical size affect the irrigation activation? the microbial load after chemomechanical cleaning of the root canal and after irrigation activation will be compared between two groups (with different apical shaping size) to analyse the effect of apical shaping on irrigation activation. Droplet Digital PCR results before and after irrigation activation in root canals with different apical size will be compared to measure this outcome. |
