The objective of the present study is to evaluate bone loss at implant abutments coated with a soda-lime glass containing silver nanoparticles subjected to experimental peri-implantitis. Five beagle dogs were used in the experiments, 3 implants were installed in each quadrant of the mandibles. Glass/n-Ag coted abutments were connected to implant platform. Cotton floss ligatures were placed in a submarginal position around the abutment necks and the animals were subject to a diet which allowed plaque accumulation, and after 15 weeks the dogs were sacrificed. Radiographs of all implant sites were obtained at the beginning and at the end of the experimentally induced peri-implantitis. The radiographic examination indicated that significant amounts of additional bone loss occurred in implants without biocide coating, considering both absolute and relative values of bone loss. Percentages of additional bone loss observed in implants dressed with a biocide coated abutment were about 3 times lower (p<0.006 distal aspect; and p<0.031 at mesial aspect) than the control ones. Within the limits of the present study it seems promising the use of soda-lime glass/nAg coatings on abutments to prevent peri-implant diseases.

“…Nano silver is one such example, which is known to attack a broad range of biological processes in microorganisms and disrupt the cell membrane structure and functions (McDonnell and Russell 1999 ;Sondi and Salopek-Sondi 2004 ). It also inhibits gene expression for the proteins associated with ATP production (Yamanaka et al 2005 Gajbhiye et al 2009 ;Esteban-Tejeda et al 2010 ). Besides this, the nano-based products have been used for the control of pumpkin disease and powdery mildew (Lamsal et al 2011 ).…”

“…Nanoparticles have shown to be effective against a verity of plant pathogens and insect pests. Several different formulations of insecticides, pesticides and insect-repelling chemicals are reported (Esteban-Tejeda et al 2010 ;Zahir et al 2012 ). It is now possible to deliver any desired chemical into the plant tissues for eliciting the host plant defence against the pest insects (Torney 2009 ).…”

Nanotechnology offers immense opportunities for improvement in the quality of life through applications in agriculture and the food systems. Development of nanotechnology-based novel agro-products, viz., nanosensors, nano-fertilizers, nano-pesticides and nanoformulations of biocontrol agents, is currently a subject of intense investigation. A variety of nanomaterials has been recommended for use in agriculture, in order to help reduce the consumption of agrochemicals by use of smart delivery systems, minimize the nutrient losses and increase the yield through optimized water and nutrients management. Nanotechnology-derived devices have also been explored in the areas of plant breeding and genetics. Additionally, the agricultural products and/or by-products can be utilized as a source for developing bio-nanocomposites. Nevertheless, the potential advantages of nanotechnology applications in the agricultural sector are still marginal, and have not been commercialized to a signifi cant extent, as compared to other industrial sectors. Researches in the area of agricultural nanotechnology are being extensively pursued in quest for the solutions to the agricultural and environmental challenges, such as sustainability, increased productivity, disease management and crop protection through innovative techniques for monitoring, assessing and controlling the agricultural practices. This chapter provides a basic knowledge about the role of nanotechnology in developing sustainable agriculture and environment, and eventually in the welfare of human society, at large, in the near future.

“…Finally, it has to be mentioned that silver has been also used in its metallic form as coating on glass particles (Wren et al , 2012), or as the dispersed phase within glass matrices (Cabal et al , 2011;Esteban-Tejeda et al , 2010;Claxton et al , 2002;Troczynski and Nicholson, 1990). …”
