Tissue engineering is a multi-disciplinary field, which aims to apply innovative biomaterials to replace or restore ill or damaged tissues of the human body, such as skin and bones. In particular, porous scaffolds are used as temporary 3D templates to support cell attachment and proliferation during the spontaneous regeneration of natural tissues and this approach is particularly promising for ...
OBJECTIVES The aim of the present study was to test cutting efficiency of different materials against conventional alumina in an air abrasion system. MATERIALS AND METHODS The powder samples were divided into three groups: Group 1 - alumina (control), Group 2 - 45S5 bioactive glass, and Group 3 - hydroxyapatite. 30 microscope glass slides of 0.5 mm thickness were used as an alternative of hum...
Bioactive glasses have been shown to stimulate osteogenesis both in vivo and in vitro. However, the molecular mechanisms underlying this process are still poorly understood. In this study, we have investigated the behaviour of osteoblast-like cells (MG63), cultured in the presence of bioglass particles. Three types of granules were used: 45S5 bioactive glass, 45S5 granules preincubated in tris ...
