In this study, a gel/liquid interface is utilized for growing new (calcium-phosphate)/carrageenan garden. The hydrogels are made from carrageenan loaded with either sodium phosphate or calcium chloride, while the interfaced solution contains source of salt not used in (i. e. sodium-phosphate hydrogel calcium-chloride and vice versa). physical chemical properties tubes grown both systems same am...

Zirconium and its alloys have many applications in orthopedic medicine and compared to stainless steel, titanium and other metals used in the manufacture of implants has higher strength and corrosion resistance. Research shows that the method of preparation and surface modification before coating process has a significant impact on improving the metal implants among which include the sandblasti...

Introduction: Glass ionomer cement (GIC) is a restorative material used in pediatric dentistry, which attaches to dental hard tissues and has cariostatic properties due to the ability for fluoride release. The present study aimed to assess the fluoride release and uptake capacity of two GICs in the presence of various fluoride sources. Methods: This in-vitro study was conducted on 120 disks com...

This study compared the in vitro marginal integrity of open-sandwich restorations based on aged calcium silicate cement versus resin-modified glass ionomer cement. Class II cavities were prepared on 30 extracted human third molars. These teeth were randomly assigned to two groups (n = 10) to compare a new hydraulic calcium silicate cement designed for restorative dentistry (Biodentine, Septodon...

Background and Aim: To investigate the radiopacity of different luting, lining and filling dental cements used in prosthetic dentistry in comparison with human and bovine dental hard tissues. Material and methods: Eight cylindrical samples of each material (6 x 1 mm) were prepared from Aqualox (APC), Durelon (DE) and Adhesor Carbofine (ACF) zinc polycarboxylate cements, Cavex zinc oxide eugenol...

information about forms of phosphorus (p) is important for the evaluation of p status in soil and also understanding of the soil fertility and plant nutrition. to obtain such information and to determine the relationship between the p forms from soil characteristics, amount of different organic and inorganic p forms of 20 soil composite samples of eastern azerbaijan province, iran were determin...

objective: bioactive glass is often used as a filler material for repair of dental bone defects. in different studies osteogenic potential of this material was proved, but its dentinogenesis property is in doubt. the purpose of this study was to evaluate the histological pulp responses of calcium hydroxide and bioactive glass placed directly on exposed pulp tissues. materials and methods: twent...

Bioactive glasses have developed into a variety of items that are used in order to treat wide range medical problems. Apart from being mostly applied the healing processes hard tissues, bioactive becoming very popular materials soft tissues healing. exhibited ability accelerate skin regeneration by enhancing angiogenesis and collagen deposition proliferation stage, as well positive effects on a...
