Bulk-Fill Composite Restorations: Clinical Evaluation

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.
