|Abstract||A sialolith observed in the Wharton's duct of a male patient was resected using an Nd:YAG laser. This is the first report on the resection of sialolith using laser. The resected sample was analyzed for structural details using Fourier transform infrared (FTIR), FT-Raman, and fluorescence spectroscopic techniques. Other techniques like energy dispersive X-ray analysis, scanning electron microscopy, and thermal analysis were also used for the analysis of structural details. The major peaks of the vibrational spectra are observed to be due to the vibrations of the phosphate and hydroxyl groups of the inorganic part of the sample and the proteinaceous component of the organic part. The major elements in the sample are identified as calcium and phosphorous in the ratio 7:3. The fluorescence spectra recorded at excitation wavelengths 280, 325, and 410 nm showed emission maxima corresponding to the endogenous fluorescence of structural proteins and amino acids. The inorganic part of the sialolith remained stable even at temperatures up to 1,673 K. The spectroscopic studies indicated that the structure of the sialolith is similar to that of the dentine part of the human teeth. In situ disintegration of the sialolith involves very high temperature. High calcium and phosphorous content in the food may be attributed to one of the reasons for the formation of sialoliths.|

Ministry of Human Resource Development (MHRD) under its National Mission on Education through Information and Communication Technology (NMEICT) has initiated the National Digital Library of India (NDLI) project to develop a framework of virtual repository of learning resources with a single-window search facility. Filtered and federated searching is employed to facilitate focused searching so that learners can find out the right resource with least effort and in minimum time. NDLI is designed to hold content of any language and provides interface support for leading vernacular languages, (currently Hindi, Bengali and 9 other languages are available). It is designed 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 being developed to help students to prepare for entrance and competitive examinations, 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 being developed at 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 Human Resource Development (MHRD), through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
