About this study

The purpose of this prospective clinical trial will be to evaluate the efficacy of an FDA approved and marketed universal dental adhesive formulation in adult noncarious cervical lesions using self-etch and selective etch approaches.

The hypothesis is that using a selective enamel etch with this universal adhesive will enhance the restoration margin performance.

Read the detailed description

The purpose of this prospective clinical trial will be to evaluate the efficacy of a newly formulated universal dental adhesive formulation in adult noncarious cervical lesions using self-etch and selective etch approaches.

Thirty-three patients with at least two non-carious cervical lesions will receive one restoration utilizing the self-etch universal adhesive with no separate enamel etching and another restoration utilizing the universal adhesive and a a selective etch protocol in which in which enamel is etched with 37% phosphoric acid.

After a screening/baseline visit at which the restorative procedures listed above will conducted, the patient will be seen at recall visits after approximately 6, 12 and 24 months to observe sensitivity, retention, marginal discoloration and marginal adaptation.

Being tested
Self etch enamel etching, selective etch protocol, Adhese Universal

What participants receive

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

  • Self etch enamel etchingProcedure or surgery

    Also called Adhese Universal, Ivoclar Vivadent

    The adhesive will be applied according to manufacturer's instructions. If the lesion is greater than 2 mm in any dimension, incremental placement of Tetric EvoCeram composite (Ivoclar Vivadent) will occur with the first increment being placed against enamel.

  • selective etch protocolProcedure or surgery

    Total Etch (37% phosphoric acid; Ivoclar) will be placed on the enamel margin with no intentional placement on the dentin within the lesion. The adhesive will then be applied as instructed by the manufacturer. Tetric EvoCeram composite will be placed, light-cured, finished, and polished in the same manner as for the self-etch group.

  • Adhese UniversalDevice

    the universal adhesive, Adhese Universal , will be applied to the selected tooth following manufacturer instructions

What is being measured

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

  1. Retention of Restorations

    The primary outcome measure will be restoration retention. In these non-retentive dental lesions, the adhesive will be the only mode of retention. Failure of the adhesive would result in loss of the restoration.

    Measured: 6, 12, 24 months

Secondary outcomes (1)
  1. Number of Restoration Margins Marked as Stained or Discolored

    The secondary outcome measure was the presence of discoloration of restoration margins as determined by blinded evaluators.

    Measured: 6, 12, 24 months

Questions about this trial

What is this clinical trial studying?

A study testing Self etch enamel etching, selective etch protocol and Adhese Universal in people with Cervical Lesions, run by Indiana University at 1 site in United States.

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 6 inclusion and 7 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 28 May 2019. 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 United States. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 28 May 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Retention of Restorations (time frame: 6, 12, 24 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 28 May 2019.
