Repair of Proximal Restoration Resin Bulk Fill. Clinical Trial

November 2, 2022 updated by: Patricio Vildosola Grez, Universidad Nacional Andres Bello

Repair of Proximal Restoration With Resin Composite Bulk-Fill. Double Blind Randomized Clinical Trial

Bulk Fill" (RBF) composite resins (RC) has been on the market, with the main advantage of being applied in a single layer, faster and easier than a conventional RC. Repair of RC restorations is a validated treatment option in dentistry, which has been shown to increase the longevity of restorations by minimizing tooth damage such as complete replacement. Currently there are no clinical studies that support the actual performance of RBF repair

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Main objective: Compare the clinical performance with FDI of repairs proximal RC restorations between a conventional resin and a RBF in a period of 24 months. Hypothesis: There is not different clinical performance of proximal RC repairs done with RBF when compared to conventional RC repairs. Material and method: 80 volunteer patients will be randomly recruited to attend the clinic of the Faculty of Dentistry of the University of Chile who have two proximal RC restorations with indication of repair according to the FDI system (n per group = 80). Each patient must accept and sign an informed consent. The repairs will be randomly divided into two groups on the same patient. Control Group: Conventional RC repair (Z350 XT). Experimental Group: RBF (Tetric Evoceram Bulk Fill) Repair. For the restorative technique, a three-step adhesive with acid-etched enamel-dentin will be used. It will be evaluated at 2 weeks (Baseline), at 6, 12, 18, 24 months by two blind and calibrated evaluators (Cohen Kappa> 0.8). The data will be analyzed with the SSPS 21.0 software and the Friedman, Wilcoxon and Mann Whitney tests will be applied with a significance level of 95%.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
