Decalcification is a routinely carried out procedure by oral pathologists, as the lesions involving the pulp can only be seen and identified through decalcified sections. The present methods involve usage of chemical agents, either with inorganic acids which dissolves the calcium to form soluble calcium salts or with chelating agents. Even though the chelating agents preserve the tissue morphology and show excellent microscopic picture, it has less diagnostic efficacy, as the time taken for it to decalcify the specimens is considerably high. It becomes important for us to develop a decalcification technique which will be faster and will maintain the balance between decalcification speed and tissue morphology. Hence, the aim of this study was to develop a portable rapid decalcification unit and compare the efficacy among all the three-decalcification procedure using teeth and bone specimens, namely the conventional method, microwave method and electrolytic method
