About this study
Official title: Antimicrobial Impact of Various Root Canal Final Irrigation Activation Techniques (Clinical Study)
This randomized clinical study aims to evaluate microbial reduction in root canals after using different final irrigation activation techniques including passive ultrasonic irrigation, XP-endo Finisher file and Laser ablation with Indocyanine green dye in comparison to manual dynamic activation.
- Being tested
- manual dynamic agitaion, ultrasonic activation, xp-endo finisher, laser
- Keywords
- Irrigant activation, ultrasonic, xp-endo finisher
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
manual dynamic agitaionOther
5 mL of 2.5% NaOCl solution will be activated with a well-fitting gutta-percha cone that will be placed to full working length and then will be moved in push-pull strokes of 2 mm amplitude at a frequency of 100 strokes in about 1 min
ultrasonic activationOther
5 mL of 5.25% NaOCl solution will be activated with PUI using a #20 endosonic file that will be driven by an ultrasonic device on medium power setting for 1 minute and inserted 1 mm short of the working length
xp-endo finisherOther
5 mL of 5.25% NaOCl solution will be activated with XP-Endo Finisher which will be used in the canal for 1 minute at 800 rpm and 1 Ncm up to the working length and in slow up-and-down movements at 7-8mm length according to the manufacturer's recommendations
laserOther
First, root canals will be filled with 0.5 mL of 0.05% ICG dye and left in place for 1 minute as preirradiation time. A #20 laser fiber will be inserted into the root canals to the working length. Then infrared diode laser with a wave length of 810 nm will be used to activate the dye for 30 seconds. For activation, circular movements will be performed along with the fiber removal movement . After the first activation, dye will be reintroduced, the laser fiber will be inserted again, and a new activation cycle of 30 seconds will be performed similarly to the previous one

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Randa A Elsobky (+201019980198, dody.elsobky@yahoo.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
bacterial count (time frame: 24-48 hours). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Jul 2025; AzTrials last refreshed its copy on 6 Nov 2026.
