Study Details

Study Description

Brief Summary

ABSTRACT Objective The aim of this study was to evaluate the clinical performance of one microhybrid and two bulk-fill resin composites in Class II cavities for up to two years.

Materials and methods In total, 75 Class II restorations were made in 25 patients, using three restorative materials: two nanohybrid bulk-fill resin composites, Sonic Fill (SF) and x-tra fil (XF), and a microhybrid composite, Filtek Z-250 (FZ). The restorations were blindly evaluated by two examiners at baseline and at 6, 12, and 24 months, using U.S. Public Health Service (USPHS) criteria. The restoration groups for each category were compared using the Pearson chi-square test, and the Cochran Q-test was used to compare the changes across different time points within each restorative material (p <0.05).

    Primary Outcome Measures

    1. Clinical Acceptability [Twenty-Four-Month]

      One week after restoration placement (baseline), patients were recalled and restorations were examined clinically. Direct clinical evaluation of restorations was performed using the USPHS criteria by two independent investigators using mirrors, probes, and bitewing radiographs and scored as Alpha, Bravo, or Charlie. Alpha corresponded to excellent, Bravo to clinically acceptable, and Charlie to clinically unacceptable results. Patients were recalled at 6, 12, and 24 months for assessments of the restorations, using the same criteria as at baseline. At each recall, the same two calibrated evaluators, who were blinded to the restoratives used for cavities and patients, examined the restorations. To ensure a double-blind study, the evaluators were not informed about which filling material had been used on which teeth.
