Comparative evaluation of rheological characteristics of giomers and other nano-flowable resin composites in vitro

Low shrinkage bulk-filled dental resin composites with non-estrogenic dimethacrylate

“…In this study, while the viscosity of all DRCs groups conformed to the viscosity range of commercial flowable resin composites, 12,13 Bis-EFMA/UDMA group of (40/60), (60/40) and (80/20) are more suitable for clinical use, according to the operation experiences during the experimental process. Tempered fluidity is conducive to releasing more polymerization shrinkage stress through flow deformation before reaching the gel point, thus reducing volume shrinkage and edge microleakage, 66,67 which also corresponds to the VS and SS results below.…”

“…6 After curing, this type has high hardness and good mechanical properties. 10 The low viscosity bulk-fill DRCs have the characteristics of high fluidity (31.8-2200 Pa s), [11][12][13] high double bond conversion rate and good self-leveling, 14 which make them indispensable in clinical operation. These materials possess good wetting ability, which favors their adaptation to the cavity walls with decreased risk for air entrapment and void inclusion 15,16 and makes it possible to place them by injection with syringes.…”

Hydroxyapatite Reinforced Polyvinyl Alcohol/Polyvinyl Pyrrolidone Based Hydrogel for Cartilage Replacement

“…As well, an oscillatory frequency sweep analysis was performed at a frequency range of 0.1–100 Hz with a 1% fixed strain. The complex modulus of the components, such as storage and loss modulus, were investigated [ 45 ].…”
