UV-VIS spectra and photoinitiation behaviors of acylphosphine oxide and bisacylphosphine oxide derivatives in unfilled, light-cured dental resins.
The aims of this study were to investigate the photoinitiation behaviors of acylphosphine oxide (APO) and bisacylphosphine oxide (BAPO) derivatives in comparison to D,L-camphorquinone (CQ)/tertiary amine (EDAB) system. Fifty six kinds of experimental unfilled, light-cured resins were prepared using APO, BAPO, CQ, EDAB, resin monomers, and adhesive monomers. The measurements of ultraviolet-visib...

calorimeter <photo-DSC) and degTee of conversion (DC) determination were performed. Results showed that the UV-VIS spectTa ef all APO and BAPO derivatives possessed 2max ranging between 365 and 416 nm, Their photoinitiation behaviors were not infiuenced by acidie adhesive menomers formulated in unfilled Bis-GMA-based resins (p<O.05). Although BAPO exhibited higher reactivity than CQfEDAB in unf...
متن کاملMechanical properties of light-cured composite resins cured through filters that simulate enamel.
The light-attenuating effects of enamel on the mechanical properties of light-cured composite resins were evaluated using simple experimental filters. Three filters were designed to simulate the light transmittance characteristics of 0.5, 1.0, and 1.5 mm thick human enamel. The Knoop hardness numbers (KHN) and the elastic modulus in transverse tests for twelve shades of three light-cured compos...
متن کاملContributions on the Study of the Compressive Strength of the Light-Cured Composite Resins
The mechanical properties of the light-cured composite resins are related to the material composition, but also vary according to the light-source characteristics used for polymerization. In this study we followed the compressive strength variation for a light-cured composite resin according to the time of exposure to the curing light. With that end in view,18 test pieces were made from a light...
متن کاملEffect of monomer structure on the mechanical properties of light-cured composite resins.
The effects of monomer structure on the mechanical properties of visible light-cured composite resins based on the seven types of aromatic dimethacrylates were investigated. The results of this study suggested that the mechanical properties of the composite resins were dependent upon the chemical structure of the dimethacrylate monomers employed. The composites based on dimethacrylates with hyd...
