Bioactive ceramics have received great attention in the past decades owing to their success in stimulating cell proliferation, differentiation and bone tissue regeneration. They can react and form chemical bonds with cells and tissues in human body. This paper provides a comprehensive review of the application of bioactive ceramics for bone repair and regeneration. The review systematically sum...
The use of bioactive compounds in different commercial sectors such as pharmaceutical, food and chemical industries signifies the need of the most appropriate and standard method to extract these active components from plant materials. Along with conventional methods, numerous new methods have been established but till now no single method is regarded as standard for extracting bioactive compou...
Bioactive glasses were synthesized in an inexpensive hydrothermal chemical route by the use of microwave energy irradiation. Compositional changes were carried out to synthesis bioactive glass with different Si content. Densification behavior was investigated by microwave sintering process from 700 °C to 1000 °C temperature. The powders were characterized for their physical and morphological ch...
OBJECTIVES The purpose of the present study was to evaluate bone healing in rabbit critical-sized calvarial defects using two different synthetic scaffold materials, solid biodegradable bioactive glass and tricalcium phosphate granules alongside solid and particulated autogenous bone grafts. MATERIAL AND METHODS Bilateral full thickness critical-sized calvarial defects were created in 15 New ...
BACKGROUND Bone graft procedures have been used commonly in buco-maxillo-facial surgery. For this reason, many researchers have evaluated the bone substitutes. PURPOSE The present study evaluated soft and hard tissue reactions to two different hydroxyapatites HAs (synthetic HA and natural HA) and bioactive glass implanted into the sockets immediately after extraction. MATERIALS AND METHODS ...
UNLABELLED Dental cements including the glass ionomer cement (GIC) have found widespread use in restoring tooth structures. In this study, modifications of glass ionomer cements (GICs) were made by adding bioactive glass (BAG) to GIC to obtain bioactive restorative materials. This study used polarized light microscopy (PLM) to examine the remineralization effects of the study materials on denti...
AIM The aim was to perform comparative analysis of bioactive, contemporary bulk-fill resin-based composites (RBCs) and conventional glass-ionomer materials for flexural strength (FS), diametral tensile strength (DTS), and Vickers hardness number (VHN) in the presence of thermocycling. MATERIALS AND METHODS Five restorative materials [Tetric N-Ceram Bulk Fill; smart dentin replacement (SDR) Fl...
due to the importance of the plant extracts and classification of them as gras, blending them with food packaging materials based on dietary biopolymers attracts a great attention recently. polysaccharides (eg. chitosan, alginate) and proteins (such as soy and whey protein isolate, gelatin and zein) act as polymeric carriers for transporting a variety of bio active extracts like green tea extra...
Ideally, bioactive ceramics for use in alveolar ridge augmentation should possess the ability to activate bone formation and, thus, cause the differentiation of osteoprogenitor cells into osteoblasts at their surfaces. Therefore, in order to evaluate the osteogenic potential of novel bone substitute materials, it is important to examine their effect on osteoblastic differentiation. This study e...
