Dental compositions

A two part composition for sealing and/or filling root canals. One or more elastomeric (meth)acrylate oligomers are mixed with one or more diluent comonomers, one or more radiopaque fillers and one or more polymerization initiator systems. One or more antimicrobial agents may also be included in the composition. The components are mixed, undergo a setting reaction and are subsequently cured. In use, the composition is easily removed from the tooth structure if rework is needed, yet provides a tight and effective seal in the root canal. The composition also has a desirable flowable consistency and exhibits good adhesiveness with a tooth substrate.

Hypoxia-Selective Antitumor Agents. 3. Relationships between Structure and Cytotoxicity against Cultured Tumor Cells for Substituted N,N-Bis(2-chloroethyl)anilines

A series of aniline mustards with a wide range of electron-donating and -withdrawing substituents in the 3- and 4-positions has been synthesized and evaluated for cytotoxicity in cell culture to examine the potential of using nitro group deactivated nitrogen mustards for the design of novel hypoxia-selective anticancer drugs (Denny, W.A.; Wilson, W.R.J.Med Chem. 1986, 29, 879).Hydrolytic half-lives in tissue culture media, determined by bioassay against a cell line (UV4) defective in the repair of DNA interstrand cross-links showed the expected dependence on the Hammett electronic parameter, ?, varying from 0.13 h for the 4-amino analogue to >100 h for analogues with strongly electron-withdrawing substituents.Cytotoxic potencies in aerobic UV4 cultures showed a similar dependence on ?.This dependence predicted that the 4-nitroaniline mustard would be 7200-fold less potent than its potential six-electron reduction product, the 4-amino compound, in growth inhibition assays using a 1-h drug exposure.The measured differential was much lower (225-fold) because of the instability of the latter compound, but a differential of 17500-fold was observed in the initial rate of killing by using a clonogenic assay.The potential for formation of reactive mustards by reduction to the amine or hydroxylamine was demonstrated by the 4-nitroso compound, which had an aerobic toxicity similar to that of the amine.Although these features confirmed the original rationale, the 3-nitro- and 4-nitroaniline mustards had only minimal hypoxic selectivity against UV cells.Toxicity to hypoxic cells appears to be limited by the low reduction potentials of these compounds and consequent lack of enzymatic nitroreduction.However, this study has demonstrated that nitro groups can be used to latentiate aromatic nitrogen mustards and indicates that examples with higher reduction potentials could provide useful hypoxia-selective therapeutic agents.

Chlorinated poly(propylene carbonate) and preparation method thereof

This invention provides a chlorinated poly(propylene carbonate) and the preparation method thereof, the chlorinated poly(propylene carbonate) is as represented by formula (I). Compared to the prior poly(propylene carbonate)s, the chlorinated poly(propylene carbonate) has relatively stronger electronegativity due to the presence of chlorine atoms and the interaction of the chlorinated poly(propylene carbonate) with other polar materials can be enhanced, so that it can be widely used as a compatilizer, a binder, a paint, an ink, and the like. After the introduction of chlorine atoms, hydrogen bond interaction is generated within the chlorinated poly(propylene carbonate), so that its processability and mechanical properties are both improved. Furthermore, the chlorine atom may improve the flame retardancy of chlorinated poly(propylene carbonate) materials.

Preparation of Reinforced poly (BisGMA-UDMA) Graphene-Based Nanocomposites Via Moderate in Situ SET-LRP

In the present study, cross-linked poly (dimethacrylate- urethane dimethacrylate) [poly (BisGMA-UDMA)] functionalized-graphene oxide nanosheets were prepared via single-electron transfer living radical polymerization (SET-LRP) using the ?grafting from? strategy, under mild conditions. This method first involves the covalent attachment of Br-containing groups onto the surface of grapheme sheets to give the initiating-groups-containing graphene (G-Br). After that, the succeeding SET-LRP polymerization in DMSO in the presence of a Cu wire/Me6TREN catalytic system at room temperature leads to the grafting of poly (BisGMA-UDMA) chains onto the graphene surface. The resulting graphene-poly (dimethacrylate- urethane dimethacrylate) (G-PDMA-UDMA) nanocomposites were characterized using FT-IR, XRD, DSC, AFM, FE-SEM, and TEM analysis techniques. It was proved that polymer chains were successfully introduced to the surface of the graphene planes. After grafting with poly (BisGMA-UDMA), the dispersibility of the modified GO sheets significantly improved. When compared to G-PDMA, the resulting G-PDMA-UDMA nanocomposite revealed around 75%, 97%, and 65%, increase in compressive strength, Young’s modulus and toughness, respectively. Such smart graphene-based nanocomposites can be used as promising biomaterials in orthopaedic and dental applications with the desired mechanical properties.

CURABLE URETHANE DIMETHACRYLATES AND DENTAL RESTORATIVE COMPOSITIONS THEREOF

BisGMA is the most widely used resin in dental composites, however, it is being phased out for use due to potential long-term health effects. The present invention relates to a urethane dimethacrylate replacement candidate based on the reaction products of equal molar amounts of 2-hydroxypropylmethacrylate and 2-hydroxyethylmethacrylate with mixed-MDI. This resin is a viscous liquid at room temperature; however, formulations with reactive diluents produce low viscosity liquid with a refractive index comparable to bisGMA formulations, as well as having Young’s modulus comparable to bisGMA formulations. Unlike bisGMA this resin should have no negative health effects.
