Comparing Bioactive Bulk-Fill and Conventional Composites in Class II Dental Restorations A Prospective Clinical Study in Adults 18 to 50 Years

What this Trial Is About

Researchers are evaluating the clinical performance of a bioactive bulk-fill composite compared to a conventional microhybrid composite in Class II posterior dental restorations. This prospective split-mouth study includes adults aged 18 to 50 years who require at least two comparable Class II restorations. The study aims to provide evidence on the effectiveness of bioactive bulk-fill composites in improving restoration outcomes by comparing two different restorative approaches within the same individual. Participants will receive two different treatments one cavity will be restored using a bioactive bulk-fill composite Activa BioACTIVE Bulk Flow applied at the gingival base and covered with a microhybrid composite Filtek Z250, while the other cavity will be restored entirely with the microhybrid composite Filtek Z250. This split-mouth design allows direct comparison of the two materials within the same mouth, minimizing variability. Clinical performance will be assessed at baseline, 6 months, and 12 months using the FDI World Dental Federation criteria, focusing on marginal adaptation, retention, and overall clinical success of the restorations. Secondary outcomes include evaluating surface properties and marginal staining. Participants will undergo dental evaluations at these intervals to monitor outcomes and ensure safety throughout the study, which is expected to last at least 12 months per participant.
