“…M ethacrylate-based dental composites, which usually consist of methacrylate resin matrix, photoinitiator system, and coupling agent treated inorganic fillers, have been widely used in dentistry because of their excellent esthetics and easy handling properties. Since they were first introduced into dentistry 40 years ago, dental composites have achieved great development in resin matrix, inorganic fillers, and curing method, [1][2][3] and the development is still going on with the aim to obtain a safe dental composites with low polymerization shrinkage, [4][5][6] high mechanical properties, [7][8][9] antimicrobial function, [10][11][12][13][14] and so on.…”

ABSTRACT:Tricyclododecane dimethanol diacrylate (SR833s) was used to replace triethylene glycol dimethacrylate (TEGDMA) as a diluent monomer and mixed with 1,6-bis(methacryloxy-2-ethoxy-carbonylamino)-2,4,4-trimethylhexane (UDMA) to prepare 2,2-bis[4-(2-hydroxy-3-methacryloyloxypropyl)-phenyl]propane (Bis-GMA) free dental resin system, and commonly used BaAlSiO 2 dental microfillers were added into UDMA/SR833s resin to prepare Bis-GMA free dental composites. Physicochemical properties such as double bond conversion, polymerization shrinkage, water sorption and solubility, flexural strength, and modulus of UDMA/SR833s resin and relevant composites were investigated. The results showed that UDMA/SR833s resin had better physicochemical properties than UDMA/TEGDMA and Bis-GMA/TEGDMA resins. Although UDMA/SR833s-based composites had lower flexural strength and modulus than commercial dental composite Z250, they still met the International Organization for Standardization (ISO) standard requirement (in flexural strength and modulus for resin-based dental materials). Except for the flexural strength and modulus, all the other properties of UDMA/SR833s-based composites were comparable or better than those of Z250. Therefore, UDMA/SR833s resin and its relevant composites had potential to be used in dentistry as Bis-GMA free dental materials. C

“…24 Some other authors have reported similar yields for the synthesis of new bisglycidyl methacrylates. [25][26][27][28][29] FTIR spectra of these new compounds revealed that the absorption band at 910 cm 21 , corresponding to the epoxy group of the intermediate compound disappears, and new absorption shows spectra of monomers corresponding to 1 HNMR. In these spectra, distinctive signals assigned to AC@CAH cis (6.1 ppm), C@CAH trans (5.5-5.57 ppm), and ACH3 (1.9 ppm) were observed in the three novel monomers, while the two signals between 3.3-3.4 ppm and 2.7-2.9 ppm corresponding to the epoxide ACH and ACH 2 groups of the starting material disappeared.…”

Three new bisglycidyl monomers; 1,4‐bis((2‐hydroxy‐3‐methacryloxypropoxy) methyl)benzene (MB‐Phe‐OH), 1,4‐bis(2‐hydroxy‐3‐methacryloxypropoxy)2‐cis‐butene (MB‐Cis‐OH), and 1,7‐bis(2‐hydroxy‐3‐methacryloxypropoxy)heptane (MB‐1,7‐OH); were synthesized and used as Bis‐GMA/TEGDMA (bisphenolglycidyl methacrylate/triethylene glycol dimethacrylate) composite resin additives. Flexural properties and double bond conversion of the dental resins composed of silanizated inorganic filler and organic matrices containing new monomers were evaluated. The composite resins formulated, using the monomers MB‐Cis‐OH and MB‐1,7‐OH, have mechanical properties and double bond conversion comparable with those of Bis‐GMA/TEGDMA composite resin used as control. The composite containing the new monomer MB‐Phe‐OH has better flexural properties (flexural strength 65.01 MPa and flexural modulus 5675.91 MPa) than the control composite resin (flexural strength 52.85 MPa and flexural modulus 4879.72 MPa); this could be attributed to the molecular structure of the monomer and its high double bond conversion level of 74.19%. The new bisglycidyl methacrylate monomer MB‐Phe‐OH could be potentially useful in the development of new organic matrices for dental composite resins with high double bond conversion and enhanced mechanical properties. © 2014 Wiley Periodicals, Inc.

“…Endo and Kanazawa synthesized polymers using the monomer 4-vinyl benzyl phosphonium chloride as a phosphonium salt, which can be used for dental llers and examined their antibacterial activity. 27 The activity of polymers was measured against Streptococcus mutans (S. mutans) and it was found that at 10 mmol mL À1 within 24 hours, the polymers showed higher activity compared to poly (methylmethacrylate).…”
