Evaluation of the Clinical Performance of a Bulk Fill Resin Composite in Cuspal Coverage Restorations of Vital Posterior Teeth (RCT)

Evaluation of the Clinical Performance of a Bulk Fill Resin Composite in Cuspal Coverage Restorations of Vital Posterior Teeth (RCT)

This clinical study aims to compare bulk-fill and conventional composite resins in cuspal coverage restorations of posterior teeth. The primary outcomes include evaluating wear resistance, fracture incidence, and recurrent caries at different follow-up periods. Bulk-fill composites are designed for easier placement in thicker increments, potentially improving clinical efficiency. The study seeks to determine whether bulk-fill materials can provide comparable or superior performance to conventional composites in restoring structurally compromised teeth.
