Bulk-Fill Composite Restorations: Clinical Evaluation

Summary

This randomized controlled clinical study aims to evaluate the clinical performance of five different bulk-fill composite materials representing distinct technological approaches according to the World Dental Federation (FDI) criteria. The materials include a thermoviscous bulk-fill composite applied with preheating, a sonic-activated bulk-fill composite, a flowable bulk-fill composite, an ORMOCER-based bulk-fill composite, and a conventional bulk-fill composite. Restorations will be clinically assessed at baseline, 1 month, 6 months, and 12 months for esthetic, functional, and biological outcomes.

Conditions

• Composite Resins
• Dental Caries Class II

Interventions

OTHER

Thermoviscous bulk-fill composite restoration

Posterior restorations in this group will be performed using a thermoviscous bulk-fill composite material applied after preheating according to the manufacturer's instructions.

OTHER

Sonic-activated bulk-fill composite restoration

Posterior restorations in this group will be performed using a sonic-activated bulk-fill composite material with reduced viscosity during placement, according to the manufacturer's instructions.

OTHER

Flowable bulk-fill composite restoration

Posterior restorations in this group will be performed using a flowable bulk-fill composite material according to the manufacturer's instructions.

OTHER

ORMOCER-based bulk-fill composite restoration

Posterior restorations in this group will be performed using an ORMOCER-based bulk-fill composite material according to the manufacturer's instructions.

OTHER

Conventional bulk-fill composite restoration

Posterior restorations in this group will be performed using a conventional bulk-fill composite material according to the manufacturer's instructions.
