About this study

The present study aims to evaluate the performance of direct restorations with bulk fill resins in molars with great structural loss, with endodontic treatment. The behavior of class II restorations in 68 molars endodontically treated with bulk fill resin and incremental technique will be evaluated by means of a randomized clinical trial with a two-year follow-up. This project aims to evaluate the performance of this new restorative strategy that can greatly contribute to restorations of posterior teeth.

Read the detailed description

Sixty-eight endodontically treated molars were restored in 54 adolescents (10-18 years old, mean= 14.0 +- 2.4). Teeth were randomly assigned to the incremental filling technique (Filtek Z230/Vitremer, 3M-ESPE, n = 31) or high viscosity bulk fill technique (Filtek Bulk Fill Posterior, 3M-ESPE, n = 37). The restorations were clinically evaluated at baseline, 12 and 24 months by two independent raters using modified United States Public Health Service criteria. Data analysis included descriptive statistics, Mann-Whitney and Friedman non-parametric tests, and Generalized Estimating Equation (GEE) analysis.

Being tested
Direct composite resin

What participants receive

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

  • Direct composite resinProcedure or surgery

    For both groups: The teeth will have the enamel surface conditioned with 37% phosphoric acid. For the restorative procedure, the same adhesive system will be used

    GROUP ACTIVE COMPARATOR

    1. Insert resin-modified glass ionomer cement into the pulp chamber;
    2. Complete the restoration by incremental technique using conventional composite resin in increments of 2mm;

    EXPERIMENTAL GROUP

    1. Insert Bulk Fill composite inside the pulp chamber to the height of 5 mm;
    2. Complete the insertion of the Bulk Fill resin to the limit of the caval surface angle in the occlusal

Questions about this trial

What is this clinical trial studying?

A study testing Direct composite resin in people with Composite Resins, run by Renata Afonso da Silva Pereira at 1 site in Brazil.

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 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 6 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 Brazil. 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?

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?

restoration failure (time frame: 2 years). 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 6 May 2019.
