| Abstract | Composite arch-wire (CoAW) is an arch wire formed by solder connection of nickel titanium shape memory alloy and stainless steel wire. The purpose of the present study was to investigate the biocompatibility of CoAW as an important foundation for its clinical application. The electrochemical corrosion and ion release behavior of CoAW upon immersion in solutions simulating oral cavity conditions were measured to evaluate the corrosion behavior of CoAW. Murine L-929 cells were co-cultured with CoAW extract to evaluate the cytotoxicity of the corrosion products in vitro. Polarization tests indicated that CoAW is resistant to corrosion in the tested artificial saliva (AS)-based solutions (chloric solution, simple AS, fluorinated AS, and protein-containing AS), and the amount of toxic copper ions released after immersion was lower than average daily dietary intake levels. The cytotoxicity experiments demonstrated the in vitro biocompatibility of CoAW. Based on the combined advantages of its base materials CoAW, with its resistance to biocorrosion and in vitro cytocompatibility, is a promising alternative material for use in orthodontic fixation applications. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
