Functional dendritic compounds: potential prospective candidates for dental restorative materials and in situ re-mineralization of human tooth enamel

Abstract

This review provides a snapshot of recent progress in the synthesis and application of dendritic compounds as potential prospective candidates for dental restorative materials andin siture-mineralization of human tooth enamel.

Antibacterial and thermomechanical properties of experimental dental resins containing quaternary ammonium monomers with two or four methacrylate groups

“…In dental resins, the higher crosslink density of a multifunctional monomer provides a sufficient number of bridges between linear macromolecules, resulting in certain benets, such as a three-dimensional network, thereby improving the mechanical properties and melting temperature of the resin. 25 tan d indicates the damping and is a measure of how well a material disperses energy in its mass. A high tan d indicates a high molecular mobility of the material, whereas a low tan d indicates a low mobility.…”

“…Jaymand et al suggested that multi-functional and dendritic monomers can be used to improve the crosslinking degree and mechanical performance of the resin. [23][24][25] Compared to a linear monomer, monomers with multi-functional methacrylate groups provide an extremely high number of functional groups in a compact space with a high reactivity and can become a crosslinking center of the polymer. 26 At present, few studies have been conducted on QAS monomers with multi-functional methacrylate groups, and there remains a lack of data regarding their comparison with linear QAS monomers.…”

Co‐delivery of methotrexate and doxorubicin via nanocarriers of star‐like poly(DMAEMA‐block‐HEMA‐block‐AAc) terpolymers

“…Briefly, MCF‐7 cells were trypsinized, harvested and seeded in 96‐well plates. After overnight incubation, the cells were treated with 500 μg mL −1 terpolymer, drug‐loaded terpolymer and free drug for 24, 48 and 72 h. After 24, 48 or 72 h, the media containing drugs were removed and 50 μL of MTT solution was added to each well followed by 150 μL of cultivation medium, then placed in a cell culture incubator for 4 h. Finally, the remaining MTT solution aspirated, the formed formazan crystals were dissolved in DMSO and absorbance was measured at 570 nm using a spectrophotometric plate reader (ELx 800, Biotek, San Francisco, CA, USA) …”

Preparation of a highly crosslinked biosafe dental nanocomposite resin with a tetrafunctional methacrylate quaternary ammonium salt monomer

“…Jaymand et al suggested that multifunctional and dendritic monomers can be used to improve the crosslinking degree and performance of the resin. [33][34][35] Monomers with multifunctional methacrylate groups provide a very high number of functional groups in a compact space that has high reactivity and can become a crosslinking center of the polymer. 36 There have been few studies on QAS monomers with multifunctional methacrylate groups.…”
