About

the current study was conducted to evaluate and compare the flowable short fiber-reinforced (SFRC) and flowable bulk-fill resin composites (BFCs) regarding their 4-year clinical performance as dentin replacement materials in class II cavities.

Full description

the current study was conducted to evaluate and compare the flowable short fiber-reinforced (SFRC) and flowable bulk-fill resin composites (BFCs) regarding their 4-year clinical performance as dentin replacement materials in class II cavities. Forty patients were enrolled in the study. Each patient received three class II cavities; one of them was restored with flowable SFRC for dentin replacement, while in the other two cavities, dentin was replaced with two different flowable BFCs. The three dentin replacements were veneered with one particulate filler resin composite (PFC) (Essentia, GC). World Dental Federation (FDI) criteria were used for clinical assessment of the restorations at 1-week (baseline), 6, 12, 18-months, 2, 3, and 4-year intervals.

Enrollment: 120 patients
