Clinical Performance of Three Different Restorative Materials

The clinical performance of a bioactive composite (alkasite-based), a nanohybrid resin composite and a bulk-fill resin composite in class II restorations will be evaluated and compared. After recruiting participants with at least 3 approximal caries lesions, all restorations will be placed by a single clinician. All caries lesions will be removed before restoring. Cavities will be divided into three groups: a bioactive composite \[Cention Forte Ivoclar Vivadent, Schaan, Liechtenstein\], a nanohybrid resin composite \[Tetric N-Ceram2 (Ivoclar Vivadent, Schaan, Liechtenstein)\] and a bulk-fill resin composite \[Tetric N-PowerFill2 (Ivoclar Vivadent, Schaan, Liechtenstein)\], All restorative procedures will be conducted according to manufacturers' instructions. Restorations will be scored using FDI criteria after a week (baseline) 6, 12, 24, 36 and 48 months. Descriptive statistics will be performed using chi-square tests.
