NCT06212141

Brief 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.

Outcome Measures

Primary Outcomes (5)

  • Marginal Adaptation

    Observers evaluated the restorations was performed using the modified United State Public Health Service criteria regarding marginal adaptation. Marginal adaptation was evaluated by an independent clinician. Visual inspection with a mirror was performed . Scores; Alfa: Closely adapted, no visible crevice. Bravo: Visible crevice, explorer will penetrate. Charlie: Crevice in which dentin is exposed

    From baseline to 18 month

  • Marginal Staining

    Observers evaluated the restorations was performed using the modified United State Public Health Service criteria regarding marginal staining. Marginal staining was evaluated by an independent clinician. Visual inspection with a mirror was performed . Scores: Alfa: No discoloration. Bravo: Discoloration without. Charlie: Discoloration with penetration in pulpal direction

    From baseline to 18 month

  • Retention

    Observers evaluated the restorations was performed using the modified United State Public Health Service criteria regarding retention rate. Retention rate was evaluated by an independent clinician. Scores: Alfa: No loss of restorative material. Charlie: Any loss of restorative material

    From baseline to 18 month

  • Seconder caries

    Observers evaluated the restorations was performed using the modified United State Public Health Service criteria regarding retention rate. Retention rate was evaluated by an independent clinician. Scores: Alfa: No caries present. Charlie: Caries present

    From baseline to 18 month

  • Postoperative sensitivity

    Observers evaluated the restorations was performed using the modified United State Public Health Service criteria regarding retention rate. Retention rate was evaluated by an independent clinician. Scores: Alfa: Not present. Bravo: sensitive but diminishing in intensity. . Charlie:constant sensitivity, not diminishing in intensity

    From baseline to 18 month

Study Arms (3)

VisCalor Bulk

ACTIVE COMPARATOR

Thermoviscous Bulkfill composite resin Warming of the material makes it flowable for the application and then sculptable immediately afterwards (thermoviscous technology) Optimal flowing to margins and undercut regions One universal and three aesthetic shades Cannula form

Device: VisCalor Bulk,VOCO,Germany

Admira Fusion x-tra

ACTIVE COMPARATOR

Ormocer based bulkfill composite Purely ceramic-based, bulk fill restorative material Reliable curing of 4 mm layersby far the lowest polymerisation shrinkage (1.25 % by volume) and particularly low level of shrinkage stress, providing optimal marginal integrity. inert, so excellent biocompatible and extremely resistant to discolouration Easy handling, simple high-lustre polishing procedure coupled with high surface hardness guarantee first-class long-term results Universal shade with chameleon effect

Device: Admira Fusion x-tra,VOCO,Germany

Filtek One Bulk

ACTIVE COMPARATOR

Conventional bulkfill compositeFocused options powered by 3M technology help you complete posterior restorations in a single bulk placement. 5 shades avaible : A1, A2, A3, B1, and C2. Excellent adaptation and sculptability for fast, easy placement. One-step placement : Tackle deep cavities with up to 5 mm depth of cure

Device: Filtek One Bulk,3M,Germany

Interventions

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.

VisCalor Bulk

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.
