Evaluation of microleakage of Ionoseal filling material as a fissure sealant agent
Introduction: Sealing pits and fissures was introduced as an approach to prevent occlusal caries for more than two decades. The aim of this study was to compare the microleakage of flow able resin reinforced glass ionomer (Ionoseal) with other materials used as fissure sealants. Methods: In this in vitro study, 50 premolar teeth of human free of any caries were selected. Fissurotomy was done...
متن کاملPlatelet-rich plasma as filling material in open sinus lift surgery
Background Many biomaterials are used during the open sinus lift surgery, beneath the elevated scheniderian membrane and maxillary sinus bony floor but the search for Ideal material continues. Methods In the maxillary posterior atrophic ridges with the bone height less than four millimeters the open sinus lift surgery performed. The autologous Platelet-rich plasma (PRF) was used as the sol...
متن کاملCoconut shells as filling material for anaerobic filters
In rural areas of developing countries, there is a lack of sanitation services and the installation of such infrastructure is hampered by the high investment costs for initial implementation and by the limited availability of qualified personnel. An alternative to traditional sanitation services include an anaerobic filter, but the high cost of appropriate filling material can be an obstacle to...
متن کاملNovel inorganic tin phosphate gel: multifunctional material.
Here, we report a remarkable 15 Å nanolayered tin phosphate, Sn(HPO4)2·3H2O (SnP-H+ or SnP), and its clay-like gel, which are multifunctional and are prepared using earth-abundant Sn and P chemicals by a facile, environmentally benign and potentially cost-effective process. This new energy material is discovered here as the best proton conductor among all the known layered phosphates with a ver...
متن کاملIndium tin oxide as a semiconductor material in efficient p-type dye-sensitized solar cells
Indium tin oxide (ITO) is a well-known n-type degenerate semiconductor with a wide variety of electronic and optoelectronic applications. Herein ITO is utilized as a photocathode material in p-type dye-sensitized solar cells in place of the commonly applied and highly colored nickel oxide (NiO) semiconductor. The application of mesoporous ITO photocathodes, [Fe(acac)3] as a redox mediator and a...
