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).
