About this study

Official title: Influence of Apical Periodontitis on the Accuracy of Three Electronic Root Canal Length Measurement Devices: An In Vivo Study

The aim of this in vivo study is to evaluate the influence of apical periodontitis (AP) on the accuracy of Dentaport ZX, Raypex 5, and i-Root electronic root canal length measurement devices.

Read the detailed description

Thirty-two single-rooted teeth scheduled for extraction, consisting of 16 teeth with AP and 16 teeth with normal periapex (NP), were selected. Access cavity was prepared and coronal portion of the canal was flared. Electronic working length (EWL) was determined by each ERCLMD according to each manufacturer's instructions. Each tooth was extracted and actual working length (AWL) was determined by inserting a size 15 K-file until the tip could be seen at a position tangential to the major foramen and then 0.5 mm was subtracted from the measurement. The distance from the AWL to the file tip was calculated and compared between the two groups by t-test. The accuracy of each ERCLMD within ±0.5 mm was compared between the groups by Fisher's test. Statistical significance was set at P < .05.

What participants receive

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

  • Electronic Root Canal Length Measurement DeviceDevice

    Also called Dentaport ZX, Raypex, i-Root

    Electronic Apex Locator is used to find the apical foramen of the root canal. It uses a weak electrical current passed through the canal by endodontic file

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Electronic Root Canal Length Measurement Device in people with Apical Periodontitis, run by Isfahan University of Medical Sciences at 1 site in Iran.

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 3 inclusion and 4 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 22 Jul 2013. 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 Iran. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Actual working length (AWL) (time frame: 6 months). 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 22 Jul 2013.
