“…Candidiasis is one of the most common human oral infections, is expressed in several clinical manifestations especially in geriatric patients with poor oral hygiene, such as patients with physical or mental disabilities and has been identified as the major causative microbial agent in denture stomatitis. [13][14][15] Mesoporous ordered silicates are inorganic 5 materials synthesized in the presence of surfactants which act as templates for poly-condensation of silicic species, a source of silica, a solvent and a catalyst. [6][7][8][9] These materials show a delay in biofilm formation compared to conventional resins or composites but some of them show polymer leakage, reduced polymerization degree and loss of their effectiveness over time.…”

The complete or partial dentures made of acrylic resins or composites constitute the support for Candida biofilm with consequent onset of stomatitis and candidiasis. In this paper polymethylmethacrylate composites containing chlorhexidine are prepared. The drug was loaded inside the mesopores of the silicate MCM-41 which had been properly silanized with an acrylic coupling agent. Four different chlorhexidine loaded composites were prepared using MCM-41 silanized with four different amounts of 3-methacryloxypropyl-trimethoxisilane. The composites prepared showed a decreased resin polymerization degree in comparison to the pure resin. Anyway the composite obtained with MCM-41 with the lowest silanization degree, showed a good polymerization degree, higher than that obtained when free chlorhexidine was added to the resin. This composite was able to decrease Candida biofilm adhesion and formation and inhibitedCandida biofilm proliferation for the duration of the test (120 days).

Hybrid inorganic–organic materials are promising systems for a variety of applications due to their extraordinary properties with intricate composite architectures composed of nanoscale inorganic moieties with organic polymers synergistically intertwined to provide both useful functionality and mechanical integrity. These materials have a high potential for future applications and therefore attract considerable interest in polymer science research during the last years. Among the various explored inorganic nanostructures, the mesoporous silica has been considered as a fascinating material to construct novel ordered and well-dispersed nanocomposites due to their high surface areas, periodic and size-controllable pore channels. This review is written with the intention to give an overview of the characterization and material properties of polymer–mesoporous silica nanocomposites. Among polymer–mesoporous silica composites, various categories including polyaniline, polypyrrole, polystyrene, polypropylene, polyethylene, epoxy, rubber, and acrylate polymer were discussed in detail.

Mesoporous silicas are inorganic materials with large surface areas, uniform framework structures and readily controlled pore diameters which are synthesized in the presence of surfactants as structure-directing agents, followed by the removal of the surfactant by extraction or calcination. Due to their characteristics, such as ordered structure, high surface area, and favorable interfacial interactions between silica surface and the polymer, they have found excellent potential application for use as reinforcing agents for several engineering polymer systems. While a large number of different synthesis approaches for the preparation of mesoporous silica-polymer nanocomposites has been reported in literature, there is nevertheless a growing need for verified synthesis methods of mesoporous silica-polymer materials. This paper presents a review of the literature on the methods for synthesizing polymer-mesoporous silica nanocomposites and discusses some unique properties of these composites.
