“…After BPA was revealed to have estrogenic activity, the application of BPA derivatives in dentistry was doubted. Though several studies have shown that Bis-GMA and Bis-EMA do not hydrolyze into BPA because the chemical structure prevents their hydrolysis at the ether linkage, [15][16][17] BPA has still been detected to be released out of Bis-GMA and Bis-EMA containing dental composites. 15,17,18 Therefore, the best way of reducing human exposure to BPA in dentistry is using methacrylate monomers not derived from BPA.…”

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

“…5 However, the application of Bis-GMA has been doubted since Bis-GMA-based dental restorative materials was reported to have estrogenic activity in a cell culture assay in 1996. 6 Though later studies have showed that Bis-GMA does not hydrolyze into the estrogenic substance BPA, 7,8 BPA has still been detected to be release out of several commercial Bis-GMA-based dental restorative materials. 7,9-11 Therefore, to decrease the human exposure to BPA, methacrylate monomers, which are not derived from BPA, should be utilized to replace Bis-GMA as base resin in dental restorative materials.…”

ABSTRACT:Because of the estrogenic effect of bisphenol A (BPA), the application of BPA derivatives such as Bis-GMA in dentistry has been doubted. In this research, Bis-GMA-free dental resin systems were prepared by mixing 1,6-bis(2 -methacryloyoxy-ethoxycarbonyl-amino)-2,4,4-trimethylhexane (UDMA), silicon containing dimethacrylate monomer (SiMA), and triethyleneglycol dimethacrylate (TEGDMA) together with different mass fraction. Double bond conversion, polymerization shrinkage, flexural strength, flexural, water sorption, and water solubility of prepared resins were investigated. Results showed that when UDMA/SiMA/TEGDMA was present in the ratio of 9:1:10 (wt/wt/wt), the obtained resin had the best comprehensive physicochemical properties and potential to be used as Bis-GMA-free dental resin.
