“…According to the results obtained, the silicon in the silanizing agents is bound by a covalent bond to oxygen on the surface of tooth enamel. It is noteworthy that the chemical bond between the previously mentioned elements is the strongest that exists in nature, in addition to being the most abundant element in the earth's crust (10,15,16).…”

“…In the literature, there are reports on the chemical modification of intra-radicular dentine by silanization with octadecyltrichlorosilane (OTS) and octadecyltrietoxisilane (TEOS). In these studies, it was demonstrated that the dentin surface acquired a better root seal on proceeding from a hydrophilic to a hydrophobic state after silanization with OTS (15,16,18).…”

Introduction. Caries is a multifactorial disease that can negatively affect dental tissues through the demineralization process, which produces acids deriving from the metabolism of carbohydrates. Some strategies to prevent this process have been proposed, such as topical fluoride application, resin-based restorations, pit and fissures sealers, infiltrated resins, vaccines, mouthwashes, and several brushing techniques. Objective. To evaluate in vitro enamel hydrophobic modification as a method of prevention against demineralization. Materials and Methods. A descriptive and comparative study was carried out. Thirty premolars extracted for orthodontic reasons were obtained, encapsulated in epoxy resin, sectioned, and sanded to obtain specimens 3mm in thickness. The samples were pretreated with NaOCl and EDTA, incubated with 1 and 4% octadeyltrichlorosilane (OTS) or with 3 and 6% octadecyltriethoxysilane (TEOS) for 5min and for 8h. Subsequently, the samples were immersed in citric acid for 2 months. The samples were analyzed by their contact angle, infrared spectroscopy, scanning electron microscopy, atomic and confocal force, before and after treatment in citric acid. Results. The samples coated with 1 and 4% OTS for 5min and 8h kept the silanizing agent on their surface after 2 months in citric acid. The treatment with TEOS was only effective at 6% with a reaction time of 5min. Conclusions. The modification with 1 and 4% OTS protects the surface of the tooth enamel from demineralization in acidic medium. The results indicate that treatment with 4% OTS is effective from 5min, which makes it appropriate in clinical practice.

“…The FTIR spectrum of PBMA shows CAH stretching of (CH 3 ) located at 2995 cm 21 . 19,20 Comparing to the starting reagents the PS r /PBMA blend presents very low intensity of the characteristic peaks, from PBMA C@O (at 1722 cm 21 ), CAO (at 1240 cm 21 ), and CC(C@O)AO (at 1153 cm 21 ); and from PS r CAC (at 1475 cm 21 ), CH 2 (at 1475 cm 21 ), and CAH (at 749 and 687 cm 21 ). 19,20 A strong band attributed to the stretching vibration of the ester carbonyl (C@O) group occurs at 1722 cm 21 , the band at 1137 cm 21 was attributed to symmetric stretching of the AC(@CO)AOAC group and the band at 1240 cm 21 was attributed to asymmetric stretching of the AC(@CO)AOAC.…”

“…Many conditions influence phase separation and the morphology of blends; among them, type of solvent, substrate wettability, substrate affinity, evaporation rate, molecular weight, temperature, chain end group, centripetal force, thickness, surface free energy, and solution concentration. The morphology may be modified in many ways: increasing the roughness, 18 functionalizing the surface, 19,20 or by removing one of the polymers from the blend with a selective solvent, which may lead to a marked topographic structure. Depending on the interaction and the V C 2017 Wiley Periodicals, Inc. degree of entanglement between polymers the process may result in discontinuous films comprised of network structures or islands and isolated patches of polymer.…”

This article describes a technique for recycling polystyrene cups (PSr) mixed with poly(butyl methacrylate) (PBMA) to produce PSr/PBMA films and subsequently PSr films by removing PBMA with a selective solvent (acetic acid), with the benefit of a reduction in environmental pollution generated by polystyrene waste. Removal of PBMA increases roughness, which generates a significant increase ( ∼34°) in the water contact angle, reaching its highest value at 128°. By increasing the hydrophobicity of surfaces, properties with important technical applications are acquired such as those used in antifouling paints, stain‐resistant surfaces, and surfaces that avoid the formation and accretion of ice on microelectronic devices. Roughness of PSr/PBMA films is significantly affected by the concentration of both polymers and by the spin rate, reaching its highest value at 2% PSr and 3% PBMA at 2000 normalrnormalpnormalm. For optimal film deposition, a cheap spin coating unit was designed and built, with a price less than 4% of that of a commercially available spin coating unit. Lastly, it was found that the data obtained with our spin coating unit is described by the Meyerhofer model with accuracy of 88% ± 3%. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.

A natural and biocompatible extract of garlic as a support, decorated with silver nanoparticles, is a proposal to generate an effective antifungal agent against dermatophytes at low concentrations. Silver nanoparticles (AgNPs) with a diameter of 26±7 nm were synthesized and their antimycotic activity was examined against Trichophyton rubrum (T. rubrum), inhibiting 94 % of growth at a concentration of 0.08 mg ml−1. Allium sativum (garlic) extract was also obtained (AsExt), and its MIC was 0.04 mg ml−1. To increase the antifungal capacity of those systems, AsExt was decorated with AgNPs, obtaining AsExt‐AgNPs. Using an AsExt concentration of 0.04 mg ml−1 in independent experiments with concentrations from 0.01 to 0.08 mg ml−1 of AgNPs, it was possible to inhibit T. rubrum at all AgNPs concentrations; it proves a synergistic effect between AgNPs and AsExt. Even if 1 % of the minimum inhibitory concentration of AsExt (0.0004 mg ml−1) is used, it was possible to inhibit T. rubrum at all concentrations of AgNPs, demonstrating the successful antimycotic activity potentiation when combining AsExt and AgNPs.
