Trial summary

Ninety asymptomatic maxillary anterior teeth with periapical lesions were treated in single versus multiple visit root canal treatment. Half of the teeth were randomly assigned to the single-visit (SV) group and received an additional final rinse with 2% CHX before obturation. Read more about this study

About this study

Official title: Efficacy of Chlorhexidine as a Final Irrigant in Single-visit Root Canal Treatment: A Prospective Comparative Study

Ninety asymptomatic maxillary anterior teeth with periapical lesions were treated in single versus multiple visit root canal treatment. Half of the teeth were randomly assigned to the single-visit (SV) group and received an additional final rinse with 2% CHX before obturation. The other teeth were treated in multiple visits (MV) with calcium hydroxide dressing. All patients were recalled and investigated clinically and radiographically for 24 months.

Read the detailed description

The aim of the study was to evaluate postoperative pain and 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. Ninety asymptomatic maxillary anterior teeth with periapical lesions were treated by a single operator using the step-back technique with manual instrumentation with 2.5% sodium hypochlorite (NaOCl) and 5% ethylenediaminetetraacetic acid (EDTA) as irrigants. Half of the teeth were randomly assigned to the single-visit (SV) group and received an additional final rinse with 2% chlorhexidine (CHX) before obturation. The other teeth were treated in multiple visits (MV), 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 24 months. Postoperative pain at 24-48 hours and changes in apical bone density indicating radiographic healing were evaluated statistically using the Mann-Whitney U-test followed by the Friedman and the Wilcoxon tests (α=.05).

What is being measured

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

  1. The rate of radiographic healing of the periapical lesion

    Follow-up visits were performed after 6, 12 and 24 months for all patients in order to evaluate radiographic status. Changes in apical bone density indicating radiographic healing was assessed by the periapical index (PAI).

    Measured: 6,12 and 24 months

Secondary outcomes (1)
  1. The level of postoperative pain

    Postoperative pain after 24 and 48 hours, was measured using a modified 4-grade visual analogue scale (VAS) ranging from 1 (no pain), 2 (mild pain), 3 (moderate pain/pain relieved by analgesics), to 4 (severe pain).

    Measured: 24 hours and 48 hours

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 8 Nov 2017. 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?

The rate of radiographic healing of the periapical lesion (time frame: 6,12 and 24 months). 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 NCT03336970, which also lists 6 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 8 Nov 2017.
