About

The aim of this study is to evaluate the clinical performance of three different bulk-fill restorative resin materials; a bulk fill resin composite, a flowable bulk fill resin composite and a fiber-reinforced resin in Class II restorations over a period of 24 months.

Full description

The objective of this study is to evaluate the 24-month clinical performance of three different bulk-fill restorative resin materials in Class II restorations. Forty patients with at least three approximal lesions in premolar and molar teeth will be participated in the study. A total of 120 Class II cavities will be restored using Tetric EvoCeram Bulk Fill (n=40), SureFil SDR flow + Ceram X mono (n=40), and everX Posterior + G-aenial Posterior (n=40) with their respective adhesives according to the manufacturers' instructions. All restorations will be placed by one operator. The restorations will be evaluated at baseline and at 6, 12, 18, and 24 months using modified USPHS criteria by one examiner. The restoration groups for each category will be compared using Pearson's chi-square test, while Cochran's Q test will be used to compare the changes across different time points within each restorative material (p<0.05).
