Biomimetic apatite deposition on polymeric microspheres treated with a calcium silicate solution.
Bioactive polymeric microspheres can be prepared by means of coating them with a calcium silicate solution and subsequently soaking in a simulated body fluid (SBF). Such combination should allow for the development of bioactive microspheres for several applications in the medical field including tissue engineering carriers. Four types of polymeric microspheres, with different sizes, were used i...
متن کاملBiomimetic calcium-silicate cements aged in simulated body solutions. Osteoblast response and analyses of apatite coating.
PURPOSE Calcium-silicate cements have been recently proposed for application in dentistry as root-end filling and root-perforation repair materials. The aim of this study was to investigate the effect of ageing of experimental calcium-silicate cements on the chemistry, morphology and in vitro bioactivity of the surface, as well as on osteoblast viability and proliferation. METHODS Two experim...
متن کاملGelatin-Modified Biomimetic Apatite Coatings
Biomimetic coatings constituted of gelatin and nanocrystalline apatite were deposited on titanium substrates from a slightly supersaturated calcium phosphate (CaP) solution enriched with different amounts of gelatin. Although the biopolymer inhibits the crystallization of the inorganic phase, as shown by the reduction of the mean dimensions of the spherical aggregates and of the degree of cryst...
متن کاملThe biomimetic apatite-cefalotin coatings on modified titanium.
Dental implant failure often occurs due to oral bacterial infection. The aim of this study was to demonstrate that antibiotic efficacy could be enhanced with modified titanium. First, the titanium was modified by anodization and heat-treatment. Then, a biomimetic coating process was completed in two steps. Surface characterization was performed with scanning electron microscopy, energy dispersi...
متن کاملEffect of Different Irrigation Solutions on the Colour Stability of Three Calcium Silicate-Based Materials
STATEMENT OF PROBLEM Previous studies have shown discoloration of mineral trioxide aggregate (MTA) in contact with root canal irrigation solutions. However, there are limited data on colour stability of other calcium silicate-based materials (CSMs). OBJECTIVES This in vitro study aimed to evaluate the colour stability of three CSMs in contact with different irrigation solutions. MATERIALS A...
