About this study

Official title: Evaluation of the Effect of Root Canal Shaping With TruNatomy on Postoperative Pain and Operative Torque Generated During Instrumentation: A Randomized Clinical Trial

The aim of the present study is to compare the effect of canal shaping using TruNatomy and RaCe rotary systems in bi-rooted maxillary premolars in terms of:

  • Post operative pain: incidence and intensity
  • Real time torque generated during mechanical instrumentation using real time torque motoring endodontic motor
  • Time needed for the instruments to reach to the full working length
Being tested
Root canal treatment using TruNaomy rotary files, Root canal treatment using race rotary instruments
Medical subject headings
Pain, Postoperative

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Root canal treatment using TruNaomy rotary filesProcedure or surgery

    Trunatomy rotary files will be used for the process of cleaning and shaping of the root canal system

  • Root canal treatment using race rotary instrumentsProcedure or surgery

    Race rotary files will be used for the process of cleaning and shaping of the root canal system

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Post operative pain using visual analogue scale

    pain after treatment would be measured with a VAS scale from 0-10 cm with zero representing the least amount of pain and 10 representing the worst pain possible

    Measured: at 24 hours post treatment

  2. Post operative pain using visual analogue scale

    pain after treatment would be measured with a VAS scale from 0-10 cm with zero representing the least amount of pain and 10 representing the worst pain possible

    Measured: at 48 hours post treatment

  3. Post operative pain using visual analogue scale

    pain after treatment would be measured with a VAS scale from 0-10 cm with zero representing the least amount of pain and 10 representing the worst pain possible

    Measured: at 72 hours post treatment

  4. Post operative pain using visual analogue scale

    pain after treatment would be measured with a VAS scale from 0-10 cm with zero representing the least amount of pain and 10 representing the worst pain possible

    Measured: at 1 week post treatment

Secondary outcomes (2)
  1. operative torque generated during instrumentation

    real time operative torque exerted on the instrument through out the shaping process and until the instrument reaches the full working length will be measured using a torque measuring motor in real time

    Measured: during treatment

  2. time required for the instrument to reach the full working length

    time required for the the instrument to reach the full length and complete the shaping process will be calculated using a Realtime torque motoring motor

    Measured: during treatment

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Root canal treatment using TruNaomy rotary files and Root canal treatment using race rotary instruments in people with Postoperative Pain, run by Cairo University at 1 site in Egypt.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 12 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.

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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Post operative pain using visual analogue scale (time frame: at 24 hours post treatment). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04616469, which also lists 3 linked publications.

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 17 Apr 2025.
