One-visit Root Canal Treatment Using Chlorhexidine as a Final Irrigant
A study testing One visit root canal treatment and Two visit root canal treatment in people with Root Canal Infection, run by Ege University.
Trial summary
A hundred asymptomatic molar teeth with periapical lesions were treated in single versus multiple visit root canal treatment. Half of the teeth were randomly assigned to the one-visit (OV) group and received an additional final rinse with 2% CHX before obturation. Read more about this study

About this study
Official title: Comparison of One-visit Root Canal Treatment Using Chlorhexidine as a Final Irrigant and Conventional Two-visit Root Canal Treatment
A hundred asymptomatic molar teeth with periapical lesions were treated in single versus multiple visit root canal treatment. Half of the teeth were randomly assigned to the one-visit (OV) group and received an additional final rinse with 2% CHX before obturation. The other teeth were treated in two visits (TV) with calcium hydroxide dressing. All patients were recalled and investigated clinically and radiographically for 48 months
Read the detailed description
The aim of the study was to evaluate the radiographic evidence of periapical healing in teeth with apical periodontitis treated in a single visit with an additional final irrigation using 2% chlorhexidine and to compare the results with conventional multiple-visit root canal treatment (RCT) with an intracanal calcium hydroxide dressing as a control group. 100 asymptomatic molar teeth with periapical lesions were treated using engine-driven nickel-titanium (NiTi) instrumentation with 2.5% sodium hypochlorite (NaOCl) and 5% ethylenediaminetetraacetic acid (EDTA) as irrigants. Half of the teeth were randomly assigned to the one-visit (OV) group and received an additional final rinse with 2% chlorhexidine (CHX) before obturation. The other teeth were treated in two visits (TV), after completion of root canal instrumentation calcium hydroxide paste was placed into the root canal and root canal obturation was performed in second visit. All patients were recalled and investigated clinically and radiographically for 48 months. Changes in apical bone density indicating radiographic healing were evaluated.

What is being measured
The primary outcome is the main question the study is designed to answer.
Clinical healing according to presence of clinical symptoms
All patients were called for follow up visits. The clinical healing was determined by examining clinical symptoms including presence of pain, tenderness to percussion and palpation, presence of sinus tract or swelling, and mobility. If one of these symptoms occurs, it is considered as failure..
Measured: 12 months

Changes in the size and the PAI score of the periapical lesion
The rate of radiographic healing of the periapical lesion. Follow-up visits were performed for all patients in order to evaluate radiographic status. Changes in apical bone density indicating radiographic healing was assessed using Periapical Index (PAI)(Orstavik 1986) as the scoring system.

Questions about this trial
What is this clinical trial studying?
A study testing One visit root canal treatment and Two visit root canal treatment in people with Root Canal Infection, run by Ege University.
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 16 Aug 2021. Status can change between updates, so confirm with the study contact before making plans.
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?
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?
Clinical healing according to presence of clinical symptoms (time frame: 12 months). The study lists 6 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 NCT05006209, 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 16 Aug 2021.
