Bone grafts are currently the major family of treatment options in modern reconstructive dentistry. As an alternative, stem cell-scaffold constructs seem to hold promise for bone tissue engineering. However, feasibility encapsulating dental-derived mesenchymal cells scaffold biomaterials such as alginate hydrogel remains be tested. The objectives this study were, therefore, to: (1) develop injectable based on oxidized microbeads periodontal ligament (PDLSCs) and gingival (GMSCs); (2)...
The host immune system is known to influence mesenchymal stem cell (MSC)‐mediated bone tissue regeneration. However, the therapeutic capacity of hydrogel biomaterial modulate interplay between MSCs and T‐lymphocytes unknown. Here it shown that encapsulating affects this when used encapsulate for implantation by hindering penetration pro‐inflammatory cells and/or cytokines, leading improved viability encapsulated MSCs. This combats effects T‐lymphocyte‐induced nuclear factor kappaB pathway,...
Abstract Three series of neat resins, based on methacrylates or dimethacrylates modified with 1‐[3‐(methacryl)propyl]‐3,5,7,9,11,13,15‐heptacyclopentylpentacyclo[9.5.113,9.15,15.17,13]octasiloxane (Methacryl‐POSS POSS‐MA), were evaluated. Incorporation POSS‐MA into the polymeric matrix was accomplished in three ways: ( a ) resins I formulated one‐pot copolymerization bis‐GMA/diluent monomer POSS‐MA; b copolymer 2‐hydroxylethyl methacrylate (HEMA) and POSS‐MA, weight ratio 1 : 1, first made,...

The aim of this study was to compare the integrity zirconia, lithium disilicate, and zirconia-reinforced silicate CAD-CAM crowns after being subjected cyclic loading then static until fracture.Zirconia (Zirkonzahn), disilicate (LDS, Ivoclar Vivadent AG), glass ceramic (ZLS) (Vita Suprinity, Vita Zahnfabrik) monolithic were milled (n = 6). bonded using composite resin cements under wet conditions. Three specimens from each group loaded for 10 000 cycles, other three 50 cycles with 250 N....
The adhesive interactions of block copolymers composed poly(methyl methacrylate) (PMMA)/poly(acrylic acid) (PAA) and methacrylate)/poly(2-hydroxyethyl (PHEMA) with the proteins fibronectin, bovine serum albumin collagen were studied by atomic force microscopy. Adhesion experiments performed both at physiological pH a slightly more acidic condition (pH 6.2) to model polymer-protein under inflammatory or infectious conditions. PMMA/PAA found be sensitive buffer environment than PMMA/PHEMA...

This article describes two synthetic strategies of biodegradable multi-arm star polymers with a polyhedral oligomeric silsesquioxane (POSS) core. The goal is to develop towards reinforced that can potentially be used in hard tissue engineering. were characterized including preliminary evaluation the cytotoxicity POSS-hybrid and POSS A core first strategy employed ring opening polymerization ϵ–caprolactone and/or L-lactide using Sn(Oct)2 as catalyst octa hydroxy silsequioxane initiating arm...
The purpose of this research is to demonstrate the usefulness synthesized hyperbranched multi-methacrylates (H-MMAs) in dental applications. We three multi-methacrylate oligomers and evaluated them as modifiers for use resin system: bisphenol A glycidyl dimethacrylate (BisGMA)/tri(ethylene glycol) (TEGDMA). Their photo-polymerization activities, viscosity, mechanical properties, such compression, diametral tensile, flexural strength, were evaluated. H-MMAs (10%) modified resins have lower...
This study evaluates two mechanical properties, tensile strength and tear strength, of maxillofacial materials reinforced with functional polyhedral silsesquioxane (POSS) nanoparticles at 0.0, 0.5, 1.0, 2.0, 5.0% (mass/mass) loading. Adding POSS was found to significantly affect the overall extensibility material. Significant differences were in mean peak load (p = .050) extension before failure .050), respectively, between concentrations 0% 5%. For resistance, a significant difference...
We have previously shown that hyperbranched multi-methacrylate (H-MMA)-modified dental resins VLC activities, lower polymerization shrinkage, and improved mechanical properties, compared to the 2,2-bis[4-(2-hydroxy-3-methacryloyolxypropoxy)phenyl]propane/triethyleneglycol dimethacrylate (BisGMA/TEGDMA) neat resin. The results are due unique molecular structure high weight of H-MMA intermediates. purpose this study was evaluate biocompatibility H-MMA-modified resins. cell proliferation three...
