Comparison of Bulk-Fill Composite Resins in Class II Restorations
Sponsor: Hacettepe University
Summary
The goal of this clinical trial is to evaluate the clinical performance of Class II restorations of a thermoviscous nanohybrid materials , of a bulk-fill composite resin, and of conventional nanohyribrid bulk-fill composite resins . Class II restorations will be performed in patients using three different restorative materials.And restorations will be evaluated using modified US Public Health Service criteria Resorations will be photograped and restorations will be evaluated for 6,12 months.

Conditions
Interventions
VisCalor Bulk,VOCO,Germany
It was placed class II restorations.Before applying it, a 37% orthophosphoric acid will be injected into the cavity for 30 sec. on the enamel and 15 sec. on the dentin. Then, cavity will be rinsed with pressurized air and water for 15 sec. and Futura Bond U adhesive agent will be applied to the enamel and dentin surfaces using a disposable applicator for 20 sec. Then light air pressure will be applied for 5 sec., and then polymerization will be carried out for 10 sec. using LED light. When it comes to the application of VisCalor , the VisCalor Gun , heating device will be used. A disposable composite capsule will be placed into the device, and it will be heated by selecting program 1 (65°C) for 30 sec. The material will remain hot for 2.5 min. The nozzle of the capsule on the gun will be directly applied to the deepest part of the cavity, ensuring that the material is placed from bottom to top without exceeding 4 mm. Polymerization will be carried out with LED for 10 sec.
Admira Fusion x-tra,VOCO,Germany
Admira Fusion x-tra composite resin was placed class II restorations. Before applying it an orthophosphoric acid with a concentration of 37% will be injected into the cavity for 30 sec. on the enamel and 15 sec. on the dentin. Then, cavity will be rinsed with pressurized air and water for 20 sec. And Futura Bond U adhesive agent will be applied to the enamel and dentin surfaces using a disposable applicator for 20 sec. Following the manufacturer's recommendations, light air pressure will be applied for 5 sec, and then polymerization will be carried out for 10 sec. using LED light with a power of 1200 mW/cm². Afterwards bulk-fill composite will be placed in the cavity, ensuring that each layer does not exceed 4 mm, and appropriate occlusal shaping will be performed. Polymerization will be carried out with LED light for 20 seconds.
Filtek One Bulk,3M,Germany
Filtek One Bulk composite resin was placed class II restorations. Before applyingthe material, a 37% orthophosphoric acid will be injected into the cavity for 30 sec. on the enamel and 15 sec. on the dentin, followed by rinsing the cavity with pressurized air and water for 20 sec.Then , adhesive agent will be applied to the enamel and dentin surfaces using a disposable applicator for 20 sec. Following the manufacturer's recommendations, light air pressure will be applied for 5 sec, and then polymerization will be carried out for 10 sec using LED light . Afterwards, bulk-fill composite will be placed in the cavity, ensuring that each layer does not exceed 4 mm, and appropriate occlusal shaping will be performed. Polymerization will be carried out with LED light at a power of 1200 mW/cm² for 10 sec from all directions, following the manufacturer's recommendations.
