About this study

Official title: Evaluation of the Effectiveness of Dentin Hypersensitivity Treatment Using Glass Ionomer Cements: A Randomized Clinical Trial

The aim of this randomized, double-blind, split-mouth clinical trial is to evaluate and compare the desensitizing efficacies of the resin-modified glass ionomer cement ClinproTM XT (3M ESPE, Minnesota, USA) and the conventional glass ionomer cement Vidrion R (SS White, Gloucester, UK) at 2-year follow-up.

Read the detailed description

Subjects will require to have at least two teeth in different hemiarchs with dentin hypersensitivity. Teeth will be randomized into 2 groups, receiving either Clinpro XT or the conventional glass ionomer cement Vidrion R. Prior to the desensitizing treatment (baseline), painful symptoms will be assessed by tactile and air blast tests using the Visual Analogue Scale (VAS). Treatment evaluations will be conducted up to 2-year post-treatment.

What is being measured

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

  1. Pain Scores as measured by the Visual Analog Scale (VAS)

    Tactile and air blast tests to evaluate pain with VAS

    Measured: Change from Baseline in Pain Scores at 20 minutes; at 7, 15, 21, 30 days; and after 3, 6, 12, 24 months.

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Resin-modified glass ionomer cement Clinpro XT and Glass Ionomer cement Vidrion R in people with Dentin Hypersensitivity, run by Federal University of Pelotas.

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 5 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 17 Aug 2020. 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.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

Pain Scores as measured by the Visual Analog Scale (VAS) (time frame: Change from Baseline in Pain Scores at 20 minutes; at 7, 15, 21, 30 days; and after 3, 6, 12, 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 NCT02378129, 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 17 Aug 2020.
