Comparative Evaluation of the Wear Rate of Reinforced Glass Ionomer Cement and Bulk-Fill Composite Using 3D Scan in Extracted Teeth and Its Association With Clinical Wear Rate in Class I and II Restorations: A Randomized Clinical Trial

The standardized in vitro-in vivo protocol provides a reliable framework to assess the durability and clinical relevance of reinforced GICs compared with bulk-fill composites in posterior restorations, offering insight into their long-term functional behavior under patient-related influences.
