Abstract

This study investigates how the cavity depth of restorations influences the color adjustment potential of universal shade bulk-fill resin composites. Standard cavities, with diameters of 4 mm and depths of either 2 or 4 mm, were created at the center of artificial teeth occlusal surfaces. A structural-colored bulk-fill resin composite and two pigment-incorporated universal shade bulk-fill resin composites were used. Each resin composite was placed into the cavity to assess its color adjustment potential in relation to the artificial tooth color. Following application, the resin composites' surfaces were polished using diamond-impregnated silicone polishers. Color difference analysis revealed ΔE*ab values of 3.3-4.6 and 2.2-9.6 for structural-colored resin composites and pigment-incorporated universal shade resin composites, respectively, as well as ΔE 00 values of 2.7-3.4 and 1.7-5.8 for these resin composites, respectively. These findings suggest that the tested bulk-fill resin composites' color adjustment potential was influenced by restoration depth.

Abstract

This study aimed to evaluate the bonding performance of self-adhesive flowable resin composites (SARs) to bovine teeth. Three SARs, one experimental, and two commercially available products, were used. The study parameters were shear bond strength (SBS), microleakage, and scanning electron microscopy (SEM) evaluation of bonding interfaces. The SBS of the materials was 14.1-15.1 MPa to enamel, 22.2-23.2 MPa to etched enamel, and 7.4-10.7 MPa to dentin. Specimens with pre-etching showed lower microleakage scores than those without pre-etching. SEM images of the interfaces of the materials showed excellent adaptation regardless of the substrate or etching mode. The study results indicate that enamel pre-etching can improve the bonding performance of SARs.
